+The Mono runtime is licensed under the terms of the GNU 
+Library General Public License, version 2.
+		  
+		GNU LIBRARY GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+                    675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL.  It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+  Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs.  This
+license, the GNU Library General Public License, applies to certain
+designated libraries.  This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+  The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it.  Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program.  However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+  Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+  However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.)  The hope is that this
+will lead to faster development of free libraries.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+  Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+		  GNU LIBRARY GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License").  Each licensee is
+addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    c) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    d) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+     Appendix: How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Library General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Library General Public License for more details.
+
+    You should have received a copy of the GNU Library General Public
+    License along with this library; if not, write to the Free
+    Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990

+
+2002-05-05  Daniel Morgan <danmorg@sc.rr.com>
+
+	* doc/ado-net: updated to include installation of

+
+2002-03-18  Dick Porter  <dick@ximian.com>
+
+	* configure.in: Only look for libgc on the system.  Default to not

+
+2002-03-17  Miguel de Icaza  <miguel@ximian.com>
+
+	* configure.in: Add support for building the included boehm GC.
+
+Thu Mar 7 17:19:44 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* configure.in: detect Boehm GC libs and add --with-gc switch.

+2002-02-27  Dietmar Maurer  <dietmar@ximian.com>

+
+	* acconfig.h: #undef USE_MONO_MUTEX
+

+
+2001-12-21  Dietmar Maurer  <dietmar@ximian.com>
+

+
+2001-12-21  Aaron Weber  <aaron@ximian.com>

+	current exception handling implementation.
+
+2001-11-13  Dick Porter  <dick@ximian.com>
+
+	* configure.in: Some more tests for pthread features
+	(specifically, glibc 2.1 doesnt define pthread_mutex_timedlock but
+	still needs _GNU_SOURCE for PTHREAD_MUTEX_RECURSIVE)
+
+2001-11-09  Dick Porter  <dick@ximian.com>
+
+	* configure.in: Try and get large file support, but it's not fatal
+	if it's not there (the io-layer just ignores the high word in that
+	case.)
+
+	Check for windows builds, and only bother to look for pthreads and
+	large files if we're not building for cygwin or native win32.  Not
+	having pthread support on Posix systems is now a fatal error.
+
+	* autogen.sh: Fix ACLOCAL_FLAGS - it wasn't being passed to

+	* mono/tests/Makefile.am (testjit): a new target to test the JITer
+
+	* mono/tests/jit-*: added some test for the JITer
+
+2001-09-23  Dick Porter  <dick@ximian.com>
+
+	* configure.in: Arrange to compile dummy thread support routines
+	if pthread isnt available
+	
+2001-09-23  Dick Porter  <dick@ximian.com>
+
+	* configure.in: Check for pthread.h, so that we can check for the
+	HAVE_PTHREAD_H define in config.h
+
+2001-09-21  Dick Porter  <dick@ximian.com>
+
+	* configure.in: Check for libpthread

+
+2001-09-05  Dick Porter  <dick@ximian.com>
+
+	* autogen.sh: Fixed the section that adds $ACLOCAL_FLAGS to the
+	aclocal invocation, so putting aclocal files in /usr/local works
+
+2001-08-30  Dietmar Maurer  <dietmar@ximian.com>
+
+	* *: removed the libffi dependency, mono now compiles on cygwin 
+
+	* mono/wrapper/build-dll: new file.
+
+2001-08-28  Dietmar Maurer  <dietmar@ximian.com>
+
+	* mono/tests/console.cs: impl.
+
+	* mono/tests/box.cs: impl.
+
+	* mono/tests/stream-writer.cs: impl.
+
+Mon Aug 27 20:24:26 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* mono/tests/*: New test cases, mostly for virtual method dispatch.
+	Use make testb for the slow benchmarking programs,
+	make test for the usual regression test checks.
+
+2001-08-22  Rodrigo Moya <rodrigo@ximian.com>
+
+	* mono/cil/Makefile.am:
+	* mono/wrapper/Makefile.am: use correct variables for installation
+	directories

+
+2001-08-20  Dietmar Maurer  <dietmar@ximian.com>
+
+	* mono/tests/stream.cs: new tests for the Stream class
+
+	* configure.in: I really need LIBTOOL for libmonowrapper.so, so I
+	added it again.
+
+2001-08-16  Alex Graveley  <alex@ximian.com>
+
+	* configure.in: Replace AM_PROG_LIBTOOL with AC_PROG_RANLIB. This
+	removes libtool dependency on all of Mono.
+
+2001-08-10  Dietmar Maurer  <dietmar@ximian.com>
+

+	* doc/c-sharp: removed bit about compiling

+	parameters are provided.
+
+	* status/makefile: made targets to dump info.
+	
+2001-07-15  Joe Shaw  <joe@ximian.com>
+

+* ADO.NET
+
+	The coordinator for the ADO.NET implementation is <a
+	href="mailto:rodrigo@ximian.com">Rodrigo Moya</a>, with
+	the collaboration of <a href="mailto:danmorg@sc.rr.com">Daniel
+	Morgan</a> and <a href="mailto:tim@timcoleman.com">Tim Coleman</a>.
+	
+
+* Action plan
+
+	The current plan to implement ADO.NET is as follows:
+
+	<b>Step 1:</b> Initial <a href="http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemdatasqlclient.asp?frame=true">System.Data.SqlClient</a> Provider:
+
+	<ul>
+		* Initial implementation of System.Data.SqlClient is based on
+		  the <a href="http://www.postgresql.org/idocs/">PostgreSQL C API</a> which is a
+		  client API to the PostgreSQL DBMS.  PostgreSQL was chosen so we could quickly
+		  create and test the System.Data classes.
+		  
+		* Once the <a href="http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemdatasqlclient.asp?frame=true">System.Data.SqlClient</a>
+		  code is functional and is usable by other people, we willl move it to
+		  Mono.Data.PostgreSQL, and will convert the existing
+		  System.Data.SqlClient to be just a wrapper around
+		  Mono.Data.PostgreSQL.  
+
+	</ul>
+
+	<b>Step 2:</b> <a href="http://msdn.microsoft.com/library/en-us/cpref/html/frlrfSystemDataOleDb.asp?frame=true">System.Data.OleDb</a> Provider:
+		
+	<ul>
+		* <p>On Unix systems: System.Data.OleDb will use the
+		<a href="http://www.gnome-db.org/">LibGDA</a>
+		 engine. 
+
+		  <p>LibGDA is a data access engine like ADO/OLE-DB, but for Unix.  The 
+		  GDA in libGDA stands for GNU/GNOME Data Access, but it does not require GNOME.
+		  It only requires glib2 and libxml2.  LibGDA is used by 
+		  libgnomedb, GNOME-DB, and gaSQL.  
+		  
+		  <p>There is work under way to get libgda working under 
+		  Windows using Cygwin by the GNOME-DB developers.
+		  
+		  <p>LibGDA has providers for MySQL, PostgreSQL, XML, ODBC,
+		  and MDB Tools (MS Access support).
+
+		* On Windows systems: System.Data.OleDb will use OLE-DB as
+		  its engine.  It may have the option of using libgda too.
+	</ul>
+
+	<b>Step 3:</b> <a href="http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemdatasqlclient.asp?frame=true">System.Data.SqlClient</a> Provider:
+
+	<ul>
+		* <p>System.Data.SqlClient will then become a managed
+		  provider for Microsoft SQL Server, both on Windows and
+		  Linux, to be compatible with applications written
+		  for the Microsoft .NET Development Framework.
+		  
+		  <p>Once Step 1 has been completed and the PostgreSQL
+		  provider support has been moved to its own place at 
+		  System.Data.PostgreSQL, we will use 
+		  <a href="http://www.freetds.org/">FreeTDS</a> as the basis
+		  for providing access to Microsoft SQL Server databases.
+		  
+		  <P>FreeTDS is a C API for Unix and Windows that implements 
+		  the TDS (Tabular Data Stream) protocol used in accessing 
+		  Microsoft SQL Server and Sybase databases.  A .NET Data Provider could be
+		  created for Sybase databases as well, but this would be put in Mono.Data.Sybase.
+	</ul>
+
+	<b>Step 4:</b> <a href="http://msdn.microsoft.com/downloads/sample.asp?url=/MSDN-FILES/027/001/668/msdncompositedoc.xml&frame=true">System.Data.Odbc</a> Provider:
+	
+	<ul>
+		* We will create a .NET Managaed Provider for ODBC
+		  in System.Data.Odbc for those using ODBC.
+		  On Unix and Windows, <a href="http://www.unixodbc.org/">unixODBC</a> mabye used.
+		  iODBC is an alternative to using unixODBC.
+		  
+		  <p>unixODBC works on Unix and Windows.  Well, I have not actually 
+		  used it on Cygwin, but it does build and install without problems.  
+		  
+		  <p>unixODBC has providers for:
+		  Oracle, Microsoft SQL Server and Sybase via FreeTDS, 
+		  MySQL, PostgreSQL, Informix, IBM DB2 (Universal Database), 
+		  Interbase, miniSQL (mSQL), AdabasD, Empress, YARD SQL, and others.
+		  
+	</ul>
+
+	<b>Step 5:</b> Other System.Data providers:
+
+	<ul>
+		* <p>The idea in Microsoft .NET System.Data is to have
+		  a managed provider for each supported DBMS.  System.Data.SqlClient
+		  for Microsoft SQL Server.  
+		  System.Data.OracleClient for Oracle 8i and 9i.
+
+		  <p>We will need to have Mono.Data.MySQL, Mono.Data.PostgreSQL,
+		  Mono.Data.DB2, and Mono.Data.miniSQL. Others,
+		  of course, are welcomed.
+		  		  
+		  <p>System.Data has been designed so 
+		  non-database providers can be created too.		  
+	</ul>
+	
+* Current Status
+
+	<p>We are working on Steps 1, 2, and 5.  We have only just begun on
+	steps 2 and 5 though.  We still have tons and tons of stuff to do.
+	If you have any ideas, let us know.
+	
+	<p>For Step 1, the PostgreSQL is starting to come together - it 
+	still needs a lot of work.
+	
+	<p>For Step 2, Rodrigo Moya has begun System.Data.OleDb which will use libgda
+	which is an OLE-DB/ADO data access for Unix.  The C-Sharp bindings to libgda
+	currently work - meaning they can compile, run, and you can connect to a
+	PostgreSQL database via libgda via the C-Sharp bindings to libgda.  He has also
+	added class stubs for System.Data.OleDb to cvs.
+	
+	<p>For Step 3, we need someone to start the FreeTDS .NET Data Provider so
+	we can have data access to Microsoft SQL Server and Sybase databases, or either
+	add the support in libgda.
+	
+	<p>For Step 4, we need someone to start the unixODBC .NET Data Provider, or add
+	the support in libgda.
+	
+	<p>For Step 5, we have just begun creating a Mono.Data .NET Provider - a MySQL
+	.NET Provider that uses the MySQL C Client Library.  This provider is 
+	found in Mono.Data.MySql.  We can currently connect and do a SQL INSERT and insert
+	a row into a MySQL database.  However, it currently only works on Cygwin because
+	the MySQL client library libmySQL.dll is different 
+	from the library on Linux libmysqlclient.dll.  Another problem, mysql thread functions
+	do not load for some reason.  Also, the provider only runs if you use "mint" (the Mono
+	runtime interpreter).  It does not work on "mono" (the Mono Just-In-Time compiler).
+	The C# Bindings to MySQL are thanks to Brad Meril.
+		
+	<p>We are able to do simple CREATE TABLE, DROP TABLE, UPDATE, INSERT, and
+	DELETE SQL commands using the ExecuteNonQuery method in SqlCommand.  
+	
+	<p>We can execute multiple queries and do a NextResult() in SqlDataReader()
+	to get the next result set.  
+	
+	<p>We are also able to do simple aggregate functions, 
+	ie, count(), sum(), min(), and max() 
+	in a simple SELECT SQL query using the ExecuteScalar() now.  
+	
+	<p>We are also able to retrieve data with a simple SELECT SQL query 
+	using ExecuteReader() which returns a SqlDataReader.  We are able to
+	use GetSchemaTable() to get the meta data about the table columns.  
+	We are able	to Read() to get each row from the result set.  
+	
+	<p>Here is a sample of code that is based on PostgresTest.cs and
+	TestSqlDataReader.cs tests:
+<pre>
+ 
+ static void SelectData (IDbConnection cnc) {
+	
+	IDbCommand selectCommand = cnc.CreateCommand();
+	IDataReader reader;
+
+	selectCommand.CommandType = CommandType.Text;
+	selectCommand.CommandText = 
+		"select * from pg_user;" + 

+		"select * from pg_tables;" + 

+		"select * from pg_database";

+
+	reader = selectCommand.ExecuteReader ();
+
+	do {

+		// get the DataTable that holds

+		// the schema

+		DataTable dt = rdr.GetSchemaTable();

+

+		if(rdr.RecordsAffected != -1) {

+			// Results for 

+			// SQL INSERT, UPDATE, DELETE Commands 

+			// have RecordsAffected >= 0

+			Console.WriteLine("Result is from a SQL Command (INSERT,UPDATE,DELETE).  Records Affected: " + rdr.RecordsAffected);

+		}

+		else if (dt == null)

+				Console.WriteLine("Result is from a SQL Command not (INSERT,UPDATE,DELETE).   Records Affected: " + rdr.RecordsAffected);

+		else {

+			// Results for

+			// SQL not INSERT, UPDATE, nor DELETE

+			// have RecordsAffected = -1

+			Console.WriteLine("Result is from a SQL SELECT Query.  Records Affected: " + rdr.RecordsAffected);

+		

+			// Results for a SQL Command (CREATE TABLE, SET, etc)

+			// will have a null reference returned from GetSchemaTable()

+			// 

+			// Results for a SQL SELECT Query

+			// will have a DataTable returned from GetSchemaTable()

+

+			results++;

+			Console.WriteLine("Result Set " + results + "...");

+                        			

+			// number of columns in the table

+			Console.WriteLine("   Total Columns: " +

+				dt.Columns.Count);

+

+			// display the schema

+			foreach (DataRow schemaRow in dt.Rows) {

+				foreach (DataColumn schemaCol in dt.Columns)

+					Console.WriteLine(schemaCol.ColumnName + 

+						" = " + 

+						schemaRow[schemaCol]);

+				Console.WriteLine();

+			}

+

+			int nRows = 0;

+			string output, metadataValue, dataValue;

+			// Read and display the rows

+			Console.WriteLine("Gonna do a Read() now...");

+			while(rdr.Read()) {

+				Console.WriteLine("   Row " + nRows + ": ");

+					

+				for(c = 0; c < rdr.FieldCount; c++) {

+					// column meta data 

+					DataRow dr = dt.Rows[c];

+					metadataValue = 

+						"    Col " + 

+						c + ": " + 

+						dr["ColumnName"];

+						

+					// column data

+					if(rdr.IsDBNull(c) == true)

+						dataValue = " is NULL";

+					else

+						dataValue = 

+							": " + 

+							rdr.GetValue(c);

+				

+					// display column meta data and data

+					output = metadataValue + dataValue;					

+					Console.WriteLine(output);

+				}

+				nRows++;

+			}

+			Console.WriteLine("   Total Rows: " + 

+				nRows);

+		}	

+	} while(rdr.NextResult());

+	Console.WriteLine("Total Result sets: " + results);

+			

+	rdr.Close();

+ }
+
+</pre>
+	
+	<p>We are able to get 
+	String data (char, character, text, varchar), Int16 (smallint),
+	Int32 (integer), Int64 (bigint), DateTime (time, date, timestamp),
+	Boolean (boolean), Single (float), and Double (double).
+	More data types will come later.  Note, the types that do work still 
+	need thorough testing.
+	
+	<p>Rows that are returned which contain columns that are NULL are handled now. 
+	The SqlDataReader method IsDBNull() needs to be called to determine 
+	if a field IS NULL before trying to read data from that field.
+	
+	<p>Calling PostgreSQL stored procedures works.  It does not work perfectly.  It may not
+	even work to specification - yet.  If you want to test it yourself, look at
+	TestSqlDataReader.cs or PostgresTest.cs in
+	mcs/class/System.Data/Test.  
+	
+	<p>Below, I have some sample code you can
+	use to call a PostgreSQL stored procedure named "version".  This stored
+	procedure returns a string containing the PostgreSQL server version.  Notice
+	the CommandType is StoredProcedure and the method ExecuteScalar() is called.
+	
+	<p>ExecuteScalar() is a lightweight method in class SqlCommand that only returns
+	one row and one column as one object - even if there is more than row or column.
+	
+<pre>
+ static string GetDatabaseServerVersion (SqlConnection cnc) 
+ {			 
+	SqlCommand cmd = cnc.CreateCommand ();
+	string data;
+
+	cmd.CommandType = CommandType.StoredProcedure;
+	cmd.CommandText = "version";
+							
+	data = (string) cmd.ExecuteScalar ();
+
+	return data;
+ }
+</pre>
+			
+	<p>We have the beginnings of Parameters support PostgreSQL.  Only
+	Input Parameters are currently supported.  Output, Input/Output,
+	and Return parameters still need to be done.
+	
+	<p>A lot of functionality in System.Data is missing, but the 
+	infrastructure is starting to come together.
+	
+	<p>A lot of Exceptions need to be thrown for various exceptions.  However,
+	SqlException, SqlErrorCollection, and SqlError have been partially
+	implemented.
+	
+	<p>Tim Coleman and Rodrigo Moya got the beginnings of the
+	SqlDataAdapter/DataSet/DataTable/DataRow to work.  Currently, 
+	the SqlDataAdapter can Fill() relational data into a DataTable in a DataSet.
+	See the test mcs/class/System.Data/Test/TestSqlDataAdapter.cs to see it in action.
+	Below, I show a snippets from the test:
+	
+<pre>
+ string connectionString;
+ string sqlQuery;
+ SqlDataAdapter adapter;
+ DataSet dataSet = null;
+
+ connectionString =
+	"host=localhost;" +
+	"dbname=test;" +
+	"user=postgres";
+						
+ sqlQuery = "select * from pg_tables";
+
+ adapter = new SqlDataAdapter (sqlQuery, 
+			connectionString);
+ 				
+ dataSet = new DataSet ();
+
+ adapter.Fill (dataSet);
+			
+ if (dataSet != null) {
+	foreach (DataRow row in dataSet.Tables["Table"].Rows)
+		Console.WriteLine("tablename: " + row["tablename"]);
+ }
+</pre>	
+	
+	<p>We do need help on the DataSet/DataAdaptor/DataTable/DataRelation/XML 
+	functionality so we	can integrate with 
+	the ASP.NET controls and Windows.Forms controls by allowing the controls to bind 
+	to a data source.  Gonzalo, Gaurav, Leen, Patrik, Duncan, and others are 
+	working very hard on the ASP.NET support. If you want to help, 
+	contact <a href="mailto:gonzalo@ximian.com">Gonzalo Paniagua Javier</a>
+	
+	<P>Need to add XML support in System.Data.  This involves working on
+	the classes: DataSet and XmlDataDocument and the ExecuteXmlReader() in SqlCommand.
+	
+	<p>The System.Data.dll gets built with the rest of the class library.
+	To compile the System.Data.dll assembly separately, you need:
+
+	<b>On Unix</b>
+
+	<ul>
+		* update your mono sources. Be sure you have latest mcs.exe
+		  and .dll's, since there have been many fixes needed for
+		  compilation on Linux.
+
+		* compile System.Data.dll:
+<pre>
+ cd mcs/class/System.Data<br>
+ mcs --target library -o System.Data.dll @list
+</pre>
+	</ul>
+
+	<b>On Windows</b>
+
+	<ul>
+		* update your mono sources. Be sure you have latest mcs.exe
+		  and .dll's.  You can use the same method as Linux, 
+		  or you can use NAnt.
+
+		* To use NAnt:
+
+<pre>
+ cd mcs/class/System.Data
+ ../../nant/NAnt.exe
+</pre>
+			
+			This will automatically copy the System.Data.dll to Test.
+			If you need to do a clean for the System.Data.dll assembly,<br><br>
+
+<pre>			
+ cd mcs/class/System.Data
+ ../../nant/NAnt.exe clean
+</pre>
+	</ul>
+
+* Testing
+
+	<p>In order to test System.Data.SqlClient, you will need to have
+	access to a remote PostgreSQL DBMS, or you will have to install 
+	one locally.  PostgreSQL is the DBMS used for the initial 
+	implementation of System.Data.SqlClient.
+		
+	<p>Why?  Because it is open source, has a client 
+	library that is easy to use, PostgreSQL is easy to install on
+	Unix and Windows (using the Cygwin install program), not difficult to setup after
+	installation, and it runs under: Linux, 
+	Windows (via cygwin and ipc-daemon), Unix, and
+	others.  This allowed us to create the
+	System.Data functionality in Mono much quicker.
+		
+	<p>If you plan on using a remote PostgreSQL DBMS Server,
+	than you will need to have the PostgreSQL client software on your
+	local computer that includes libpq.so (pq.dll on Windows).
+	
+	<p>The System.Data tests use this connection string to connect
+	to the PostgreSQL database named "test" at host "localhost" as
+	user "postgres".
+
+<pre>
+"host=localhost;dbname=test;user=postgres"
+</pre>
+		
+	<p>Installation instructions for PostgreSQL DBMS:
+
+	<b>On Unix</b>
+
+	<ul>
+		* Read the PostgreSQL Installation Instructions 
+		at \usr\doc\postgresql-x.x.x\html\installation.html
+		
+		* Depending on your Unix system, 
+		PostgreSQL maybe already installed, a database user 'postgres' created, 
+		a linux user 'postgres' created and initdb ran.  Or maybe not.
+
+<pre>
+ su

+ adduser postgres

+ mkdir /usr/local/pgsql/data

+ chown postgres /usr/local/pgsql/data

+ su - postgres

+ initdb -D /usr/local/pgsql/data

+ postmaster -i -D /usr/local/pgsql/data

+ createdb test

+ psql test
+</pre>
+	
+		* Make sure you have a database user named postgres.  It is best to install
+		the PostgreSQL DBMS under linux user postgres.  When you run the postmaster,
+		run it under the user postgres as well.  If this was not done, then you
+		will need to create a user named postgres for the System.Data tests.
+
+		* If you already installed PostgeSQL and you do not have a database
+		user named postgres, then you can create user postgres using psql:
+		
+<pre>		
+psql test
+create user postgres with password 'fun2db';
+</pre>
+				
+		* The postmaster must be run with -i option.
+		
+		* In the /usr/local/pgsql/data/pg_hba.conf file, you need
+		to have the AUTH_TYPE set to md5.  You can read more on this at
+		/usr/doc/postgresql-7.2.1/html/client-authentication.html 
+		or wherever your
+		PostgreSQL html docs are located.  See the 2nd line below,
+		host 127.0.0.1 has an AUTH_TYPE md5 in pg_hba.conf.
+		
+<pre>
+ # TYPE     DATABASE    IP_ADDRESS    MASK               AUTH_TYPE
+
+ local      all                                          trust
+ host       all         127.0.0.1     255.255.255.255    md5
+</pre>
+
+	* If you can not find your PostgreSQL documentation locally or you 
+	did not install it, then you 
+	can get it <a href="http://www.postgresql.org/idocs/">here</a>.
+
+	</ul>
+
+	<b>On Windows</b>
+
+	<ul>
+		* Use the <a href="http://www.cygwin.com/">Cygwin</a> installer to 
+		  install the PostgreSQL DBMS.  It is
+		  found in the database category.
+		  
+		* <p>Read the file postgres-x.x.README at /usr/doc/Cygwin and read 
+		  the requirements to install PostgreSQL.  Those requirements
+		  are included with cygwin except cygipc.  A default installtion
+		  of cygwin does not install everything you will need, so on the 
+		  safe side, just include everything when installing cygwin.
+		
+		* <p>The -x.x in postgres-x.x is the version of your PostgreSQL DBMS.
+		
+		* <p>Once Cygwin has installed the PostgreSQL DBMS on your computer,
+		  read the file FAQ_MSWIN which is available 
+		  in /usr/doc/postgres-x.x 
+				  
+		* <p>Important notes from this file are:
+		  
+		  <ul>
+				<p><b>2.</b> - Install the latest <a href="http://www.neuro.gatech.edu/users/cwilson/cygutils/OBSOLETE/V1.1/cygipc/index.html">CygIPC</a> package.
+			  			  
+				<p>The cygipc package contains the ipc-daemon you will need 
+				to run before you can
+				run the PostgreSQL DBMS Server daemon (postmaster) or run
+				initdb which initializes the PostgreSQL database.
+			  
+				<p><b>3.</b>  The Cygwin bin directory has to be placed in 
+				the path before the Windows program directories, 
+				for example, C:\cygwin\bin 
+			  
+				<p><b>My own note.</b>  In the Windows control panel, I set
+				the environment variables PATH to my cygwin /usr/local/bin,
+				/usr/bin, and /bin.  I also set my LD_LIBRARY_PATH to 
+				/usr/local/lib and /usr/lib.  For example:
+			  
+				<p>
+<pre>
+PATH=c:\cygwin\usr\local\bin;c:\cygwin\usr\bin;c:\cygwin\bin;
+LD_LIBRARY_PATH=c:\cygwin\usr\local\lib;c:\cygwin\usr\lib;
+</pre>
+							  
+				<p><b>4.</b> Start the ipc-daemon that came with the cygipc 
+				package.  There
+				are two ways to do this: run it from the command line as:
+			  
+				<p>
+<pre>
+ipc-daemon &
+</pre> 			  
+				<p>or you can set it up as a Windows service.  See the 
+				file cygrunsrv.README at /usr/doc/Cygwin on how to do this
+				for ipc-daemon and postmaster.  Note the
+				troubleshooting section at the end of 
+				the cygrunsrv.README file.
+			  
+				<p>To install ipc-daemon as a service, 
+				you just have to run
+			  
+				<p>
+<pre>
+ipc-daemon --install-as-service' (--remove-as-service) 
+</pre>
+			  
+				<p>and then run
+			  
+<pre>
+net start ipc-daemon
+</pre>
+			</ul>

+mkdir /usr/local/pgsql/data

+initdb -D /usr/local/pgsql/data

+	<p>In the path mcs/class/System.Data/Test
+	there is a PostgreSQL test program named
+	PostgreTest.cs.  Thanks goes to Gonzalo for creating the original
+	PostgreSQL test.
+	
+	<p>To use it to test System.Data, you
+	modify the file to your PostgreSQL database
+	connection requirements:
+
+	<p>
+	<ul>
+		<li><b>dbname</b> database, ie., test</li>
+		<li><b>host</b> hostname of the PostgreSQL DBMS Server to connect to, ie., localhost</li>
+		<li><b>user</b> username, ie., someuser</li>
+		<li><b>password</b> password, ie., mypass1234</li>
+	</ul>
+	
+	<p>The connection string is in OLE-DB connection string format.  Internally,
+	SqlConnection converts this to the PostgreSQL connection string format.
+	
+	<p>
+<pre>
+    OLE-DB: "host=localhost;dbname=test;user=joe;password=smoe"
+PostgreSQL: "host=localhost dbname=test user=joe password=smoe"
+</pre>
+
+	<p>
+	Note that OLE-DB includes the semicolons while PostgreSQL's connection
+	string does not.
+
+	<p>
+    To compile the PostgresTest.cs program, do:
+    
+    <p>
+<pre>
+mcs PostgresTest.cs -r System.Data.dll
+</pre>
+    
+    <p>
+    To run using mint, do:

+	export CVSROOT=:pserver:anonymous@anoncvs.go-mono.com:/mono
+	cvs login
+	cvs -z3 co mcs mono gtk-sharp
+</pre>
+
+	That will get you the compiler and class libraries (mcs), the
+	interpreter and JITer (mono) and the Gtk# bindings.
+
+	The server is located in Spain.
+
+** Updating the sources
+
+	To update your sources every day, you use this command:

+* ASP.NET
+
+	ASP.NET support is divided in two pieces:
+	<ul>
+		* Web Forms (Web Applications infrastructure).
+
+		* Web Services (the SOAP-based rpc system).
+	</ul>
+
+	There is work underway for both systems.  The Web Forms
+	support is more advanced at this point, and various ".aspx"
+	programs can be run using the Mono runtime and the XSP page
+	parser.
+
+	Tim started work on the Web Services early this week.
+	Although we have a SoapFormatter as part of the remoting
+	infrastructure already (contributed by Jesus), most people
+	will be using the ASP.NET Web-services support.  Work for the
+	supporting class libraries just started recently.
+
+* Web Forms: The pieces
+
+	There are a couple of components to the puzzle:
+
+	<ul>
+		* .aspx page parser (converts .aspx to C# code).
+	
+		* System.Web.HttpRuntime support.
+	
+		* Web controls (System.Web.UI.HtmlControls and
+		  System.Web.UI.WebControls).
+	
+		* Underlying infrastructure for the controls (System.Web.UI).
+	
+		* HttpRuntime.ProcessRequest is the core of the ASP.NET
+		  implementation.
+	</ul>
+
+
+	Gonzalo has been working on an ASP.NET parser that takes .aspx
+	files and generated the code required to run them (the code lives in
+	module `xsp' along with a little web server for testing).
+
+	Most of the runtime support was mostly written by Patrik Torstensson
+	(now at Intel).  This was interesting, because in order to implement
+	some of its features, Patrik had to go into the runtime/JIT engine and
+	he spent a few weeks doing work there.
+
+	The classes for running ASP.NET are being actively written.
+	Gaurav, Leen and Patrik worked in the core of the classes
+	required to run ASP.NET web application as well as a small
+	embeddable web server.
+
+	Duncan got our System.Web assembly to compile.
+
+** HttpRuntime
+
+	Patrik has authored most of the HttpRuntime support (both on
+	the System.Web and on the foundation) but it is still not
+	ready to run.
+
+** XSP
+
+	Currently XSP provides the .aspx compiler to C#.  It would be
+	interesting to see if it makes sense to extend the ASP.NET
+	syntax to make it simpler to develop applications.
+
+	Gonzalo is in charge of the compiler.
+
+** Controls
+
+	A lot of work has been put in the various classes that
+	implement the controls (UI.HtmlControls and UI.WebControls),
+	but they have been coded mostly in the dark, and without being
+	able to test them in real life: Gaurav and Leen worked very
+	hard on this namespace, but needs to be finished.
+
+	We can now render all HtmlControls and some WebControls. Work is
+	ongoing to make all WebControls render HTML.
+
+** Extending ASP.NET
+
+	Currently you have to reference in your ASP.NET the control
+	and all of its properties, which works fine if you have a GUI
+	designer, but is harder for people used to develop using text
+	editors.
+
+	Since we have a parser, we could extend this parser to allow
+	people to still use ASP.NET controls, using a simpler syntax.
+	For example people doing blogs and editing their templates
+	over the web probably do not want to use direct ASP.NET but a
+	wrapper around it.
+
+** Roadmap
+
+        1. The Parser.
+
+        2. Get the parser to generate output compatible with ASP.NET.
+
+        3. Run the sample output with the real Microsoft runtime
+           but using our generated page.   
+
+        4. Run the sample with our classes with the .NET runtime.
+	<b>We are here</b>.
+
+        5. Finish HttpRuntime.
+	
+        6. Running our sample code with our classes with our runtime.
+
+** How to Help
+
+        Currently we are testing and fixing HtmlControls, WebControls and
+        validators.
+
+        In the CVS module XSP you can find the aspx to C# page parser,
+        a little web server used for testing and a directory containing
+        sample aspx pages.
+
+        You have some documentation under doc directory and in the README
+        file of each directory. They explain how to test our System.Web.
+        Testing is really easy!

+* MCS: The Ximian C# compiler
+
+	MCS is currently able to compile itself and many more C#
+	programs (there is a test suite included that you can use).
+
+	We are in feature completion mode right now.  There are still
+	a couple of areas that are not covered by the Mono compiler, but
+	they are very very few at this point.
+
+	MCS was able to parse itself on April 2001, MCS compiled itself
+	for the first time on December 28 2001.  MCS became self hosting
+	on January 3rd, 2002. 
+
+	The Mono Runtime and the Mono execution engine were able to make
+	our compiler self hosting on March 12, 2002.
+
+	A test suite is maintained to track the progress of
+	the compiler and various programs are routinely compiled and
+	ran.
+
+** Obtaining MCS
+
+	The Mono C# compiler is part of the `mcs' module in the Mono CVS
+	you can get it from our <a href="anoncvs.html">Anonymous CVS</a> server,
+	or you can get nightly <a href="download.html">download page</a>.
+
+** Running MCS
+
+	MCS is written in C# and uses heavily the .NET APIs.  MCS runs
+	on Linux (with the Mono runtime) and Windows (with the .NET
+	framework runtime)
+
+** Reporting Bugs in MCS
+
+	When you report a bug, try to provide a small test case that would
+	show the error so we can include this as part of the Mono C# regression
+	test suite.
+
+	If the bug is an error or a warning that we do not flag, write
+	a sample program called `csXXXX.cs' where XXXX is the code number
+	that is used by the Microsoft C# compiler that illustrates the 
+	problem.  That way we can also do regression tests on the invalid
+	input.  
+
+** Phases of the compiler
+
+	The compiler has a number of phases:
+
+	<ul>
+		* Lexical analyzer: hand-coded lexical analyzer that
+		  provides tokens to the parser.
+
+		* The Parser: the parser is implemented using Jay (A
+		  Berkeley Yacc port to Java, that I ported to C#).
+		  The parser does minimal work and syntax checking,
+		  and only constructs a parsed tree.
+
+		  Each language element gets its own class.  The code
+		  convention is to use an uppercase name for the
+		  language element.  So a C# class and its associated
+		  information is kept in a "Class" class, a "struct"
+		  in a "Struct" class and so on.  Statements derive
+		  from the "Statement" class, and Expressions from the
+		  Expr class.
+
+		* Parent class resolution: before the actual code
+		  generation, we need to resolve the parents and
+		  interfaces for interface, classe and struct
+		  definitions.
+
+		* Semantic analysis: since C# can not resolve in a
+		  top-down pass what identifiers actually mean, we
+		  have to postpone this decision until the above steps
+		  are finished.
+
+		* Code generation: The code generation is done through
+		  the System.Reflection.Emit API.
+	</ul>
+
+** CIL Optimizations.
+
+	The compiler performs a number of simple optimizations on its input:
+	constant folding (this is required by the C# language spec) and 
+	can perform dead code elimination.
+
+	Other more interesting optimizations like hoisting are not possible
+	at this point since the compiler output at this point does not
+	generate an intermediate representation that is suitable to
+	perform basic block computation.  
+
+	Adding an intermediate layer to enable the basic block
+	computation to the compiler should be a simple task, but we
+	are considering having a generic CIL optimizer.  Since all the
+	information that is required to perform basic block-based
+	optimizations is available at the CIL level, we might just skip
+	this step altogether and have just a generic IL optimizer that
+	would perform hoisting on arbitrary CIL programs, not only
+	those produced by MCS.  
+
+	If this tool is further expanded to perform constant folding
+	(not needed for our C# compiler, as it is already in there)
+	and dead code elimination, other compiler authors might be
+	able to use this generic CIL optimizer in their projects
+	reducing their time to develop a production compiler. 
+
+<a name="tasks">
+** Current pending tasks
+
+	Simple tasks:
+
+	<ul>
+		* Redo the way we deal with built-in operators.
+	</ul>
+
+	Larger tasks:
+	<ul>
+
+		* Jay does not work correctly with `error'
+		  productions, making parser errors hard to point.  It
+		  would be best to port the Bison-To-Java compiler to
+		  become Bison-to-C# compiler. 
+		  
+		  Nick Drochak has started a project on SourceForge for this.
+		  You can find the project at: <a href="http://sourceforge.net/projects/jb2csharp/">
+		  http://sourceforge.net/projects/jb2csharp/</a>
+
+		* Semantic Analysis: Return path coverage and
+		  initialization before use coverage are two great
+		  features of C# that help reduce the number of bugs
+		  in applications.  It is one interesting hack.
+
+	</ul>
+
+** Questions and Answers
+
+Q: Why not write a C# front-end for GCC?
+
+A: I wanted to learn about C#, and this was an exercise in this
+   task.  The resulting compiler is highly object-oriented, which has
+   lead to a very nice, easy to follow and simple implementation of
+   the compiler.
+
+   I found that the design of this compiler is very similar to
+   Guavac's implementation.
+
+   Targeting the CIL/MSIL byte codes would require to re-architecting
+   GCC, as GCC is mostly designed to be used for register machines.
+   
+   The GCC Java engine that generates Java byte codes cheats: it does
+   not use the GCC backend; it has a special backend just for Java, so
+   you can not really generate Java bytecodes from the other languages
+   supported by GCC. 
+
+Q: If your C# compiler is written in C#, how do you plan on getting
+   this working on a non-Microsoft environment.
+
+   We will do this through an implementation of the CLI Virtual
+   Execution System for Unix (our JIT engine). 
+
+   Our JIT engine is working for the purposes of using the compiler.
+   The supporting class libraries are being worked on to fully support
+   the compiler.
+
+Q: Do you use Bison?
+
+A: No, currently I am using Jay which is a port of Berkeley Yacc to
+   Java that I later ported to C#.  This means that error recovery is
+   not as nice as I would like to, and for some reason error
+   productions are not being caught.  
+
+   In the future I want to port one of the Bison/Java ports to C# for
+   the parser.
+
+Q: Should someone work on a GCC front-end to C#?
+
+A: I would love if someone does, and we would love to help anyone that
+   takes on that task, but we do not have the time or expertise to
+   build a C# compiler with the GCC engine.  I find it a lot more fun
+   personally to work on C# on a C# compiler, which has an intrinsic
+   beauty.
+
+   We can provide help and assistance to anyone who would like to work
+   on this task.
+
+Q: Should someone make a GCC backend that will generate CIL images?
+
+A: I would love to see a backend to GCC that generates CIL images.  It
+   would provide a ton of free compilers that would generate CIL
+   code.  This is something that people would want to look into
+   anyways for Windows interoperation in the future.
+
+   Again, we would love to provide help and assistance to anyone
+   interested in working in such a project.
+
+Q: What about making a front-end to GCC that takes CIL images and
+   generates native code?
+
+A: I would love to see this, specially since GCC supports this same
+   feature for Java Byte Codes.  You could use the metadata library
+   from Mono to read the byte codes (ie, this would be your
+   "front-end") and generate the trees that get passed to the
+   optimizer.
+
+   Ideally our implementation of the CLI will be available as a shared
+   library that could be linked with your application as its runtime
+   support. 
+
+   Again, we would love to provide help and assistance to anyone
+   interested in working in such a project.
+   
+Q: But would this work around the GPL in the GCC compiler and allow
+   people to work on non-free front-ends?
+
+A: People can already do this by targeting the JVM byte codes (there
+   are about 130 compilers for various languages that target the JVM).
+
+Q: Why are you writing a JIT engine instead of a front-end to GCC?
+
+A: The JIT engine and runtime engine will be able to execute CIL
+   executables generated on Windows.

+* CVS Access
+
+	If you are an active Mono developer, you can get a CVS account
+	that hosts the Mono source code.  
+
+	If you are not a developer, but want to track the development, please
+	see the <a href="anoncvs.html">AnonCVS</a> instructions.
+
+	Send an e-mail to miguel with your public SSH key for this
+	purpose.  Please specify if the key was generated with SSH1 or SSH2.
+
+	If you are using SSH2, please generate your key using:
+
+<pre>
+	ssh-keygen -t rsa
+</pre>
+
+	And mail me the id_rsa.pub file.
+
+	If you are using SSH1, run:
+<pre>
+	ssh-keygen
+</pre>
+
+	And mail me your identity.pub file.
+
+	You will need CVS and SSH.  Windows users can get both by
+	installing Cygwin (<a
+	href="http://www.cygwin.com">http://www.cygwin.com</a>)
+
+	Unix users will probably have those tools installed already.
+
+** Checking out the sources
+
+	To check out the sources for the first time from the
+	repository, use this command:
+
+<pre>
+	export CVS_RSH=ssh
+	export CVSROOT=username@mono-cvs.ximian.com:/cvs/public
+	cvs -z3 co mcs mono
+</pre>
+
+** Updating your sources
+
+	Every day people will be making changes, to get your latest
+	updated sources, use:
+
+<pre>
+	cvs -z3 update -Pd mcs mono
+</pre>
+
+	Note: The '-z3' enables compression for the whole cvs action.
+	The '-Pd' makes the update operation (P)rune directories that
+	have been deleted and get new (d)irectories added to the
+	repository.
+
+** Making patches
+
+	Usually you will want to make a patch to contribute, and let
+	other people review it before commiting it.  To obtain such a
+	"patch", you type:
+	
+<pre>
+	cd directory-you-want-to-diff
+	cvs -z3 diff -u > file.diff
+	mail mono-list@ximian.com < file.diff
+</pre>
+
+** Keeping track of changes.
+
+	We provide two e-mail based mechanisms to keep track of
+	changes to the code base:
+	
+	<ul>
+		* <a href="mailto:mono-patches-request@ximian.com">
+		  mono-patches@ximian.com</a>: This mailing list receives
+		  in patch form all the changes that are being made to the
+		  CVS.
+
+		* <a href="mailto:mono-cvs-list-request@ximian.com">
+		  mono-cvs-list@ximian.com</a>: This mailing list only
+		  receives the CVS commit logs with a list of files
+		  modified.
+	</ul>
+
+	We hope to offer LXR and Bonsai in the future as well.
+
+** Commiting your work
+
+	Once you get approval to commit to the CVS, or if you are
+	commiting code that you are the maintainer of, you will want
+	to commit your code to CVS. 
+
+	To do this, you have to "add" any new files that you created:
+
+<pre>
+	cvs add new-file.cs
+</pre>
+
+	And then commit your changes to the repository:
+
+<pre>
+	cvs commit file-1.cs file-2.cs
+</pre>
+
+** The Mailing List
+
+	To keep track of the various development and changes to the
+	CVS tree, you can subscribe to the mono-cvs-list@ximian.com.
+	To subscribe, send an email message to
+	mono-cvs-list-request@ximian.com and in the body of the
+	message put `subscribe'.
+
+	This will send you an email message every time a change is
+	made to the CVS repository, together with the information that
+	the author of the changes submitted.
+	
+** Recommendations
+
+	Please do not commit code that would break the compile to the
+	CVS, because that normally wastes everybody's time.  Two things 
+	are important in this step: trying to build your sources and making 
+	sure that you add all the new files before you do a commit.
+
+	To build the sources, most of the type trying the `make' command
+	is enough.  In some cases (the class libraries) we use nant, so
+	you need to run nant manually.
+
+	Use ChangeLog entries so we can keep textual descriptions of
+	your work, and use the contents of your ChangeLog file as the
+	CVS commit message (ie, paste the contents of this into the
+	editor buffer).
+
+	If you are making changes to someone else's code, please make
+	sure you get in touch with the maintainer of that code before
+	applying patches.  You want to avoid commiting conflicting
+	work to someone else's code.

+* The Class Library
+
+	The Class Library should be compatible with Microsoft's .NET
+	implementation.
+
+	Please see the <a href="class-status.html">Class Status</a>
+	page for a status of who is working on which classes.
+	
+	We will write as much code as possible in C#. We may need to
+	interface with code written in C to gain access to the
+	functionality of libraries like libart, Gtk+, and libc.
+
+** Contributing
+
+	We welcome contributions to the the Class Library.  To get
+	started, check the status page for information about which
+	APIs are being worked on, and how to get in touch with 
+	individual maintainers.  
+
+	If you want to work on a class, first check the <a
+	href="download.html">Classes Distribution</a> to see if it is
+	not implemented yet, if not, check the <a
+	href="class-status.html">Class Status</a> to see if someone is
+	already working on it, and maybe contact them.
+
+	If nobody is working on it, mail <a
+	href="mailto:mono-list@ximian.com">mono-list@ximian.com</a>
+   	with the class you want to implement and CC <a
+	href="mailto:miguel@ximian.com">miguel@ximian.com</a>.
+
+	You can also track live the activities of the Mono CVS module
+	by subscribing to the <a
+	href="http://lists.ximian.com/mailman/listinfo/mono-cvs-list">mono-cvs-list</a>
+
+
+** Missing features
+
+	Our class libraries miss some features, for example, most classes
+	do not implement the serialization bits at all, it would be a good
+	contribution to add this to each class.
+
+	This is a simple task, but it needs to be done in a compatible way
+	with the Microsoft.NET classes: using the same arguments to serialize
+	and reincarnate data.
+
+** Layout
+
+	The Class Library resides in the `mcs' module in the directoy
+	`class'.
+	
+	Each directory in the directory represents the assembly where
+	the code belongs to, and inside each directory we divide the
+	code based on the namespace they implement.
+
+	There are two cases when we should consider portability: when
+	we are dealing with a couple of classes only that differ from
+	system to system (Consider System.Net and System.IO for Win32
+	and Unix).  In those cases we will just place the files for
+	example on <t>corlib/System/System.IO/Unix-Console.cs</t> and
+	<t>corlib/System/System.IO/Win32-Console.cs</t>.
+
+	For classes that might differ more (for example, the
+	implementation of Windows.Forms), we might have different
+	directories altogether: <t>System.Windows.Forms/Win32</t>,
+	<t>System.Windows.Forms/Gtk+</t> and
+	<t>System.Windows.Forms/Cocoa</t>.
+
+** Using existing components from GNOME.
+
+	Our current plan is to implement the GUI tools on top of
+	Gtk+.  The only obstacle here is that applications from Windows
+	might expect to be able to pull the HWND property from the
+	widgets and use PInvoke to call Windows functions.
+
+** Class Library and Win32 dependencies.
+
+	There are a few spots where the Win32 foundation is exposed to
+	the class library (for example, the HDC and HWND properties in
+	the GDI+). Casual inspection suggests that these can be
+	safely mapped to Gdk's GC and GdkWindow pointers without
+	breaking anything.
+
+	The only drawback is that support for PInvoke of Win32 code
+	won't be available.  An alternate solution would be to use
+	portions of Wine, or even to use Wine as our toolkit.
+
+*** Initial GDI+ and WinForms implementation
+
+	The initial implementation will use Gtk+ as the underlying
+ 	toolkit. Since GTK+ has already been ported to many windowing
+	systems other than X (including frame buffer, Win32, and BeOS)
+	its use should cover most applications for most users. 
+	
+*** Database access
+
+	We will implement ADO.NET functionality by reusing <a
+	href="http://www.gnome-db.org">GNOME-DB</a>. This is an ideal
+	choice, since GNOME-DB was implemented precisely to provide an
+	ADO-like system for GNOME.
+
+*** Component Integration
+
+	We will provide a new namespace to use GNOME specific features
+	as well as a namespace to host Bonobo interfaces and classes
+	in Mono.  
+
+** Licensing
+
+	The class library is being licensed under the terms of the 
+	<a
+	href="http://www.opensource.org/licenses/mit-license.html">MIT
+	license.</a>  This is the same license used by the X11 window
+	system.
+
+** Class Library testing
+
+	We need to write regression tests that will verify
+	the correctness of the class library, compiler, and JIT
+	engine.
+
+	Please write your regression tests using <a
+	href="http://nunit.sourceforge.net">NUnit</a>
+
+** Coding conventions
+
+	Please follow the conventions on the ECMA specification (On
+	the Annex Partition) for your coding your libraries. 
+
+	Use 8 space tabs for writing your code (hopefully we can keep
+	this consistent).  If you are modifying someone else's code, try
+	to keep the coding style similar.
+
+	For a rationale on 8 space tabs, read Linus Torvald's Coding
+	Style guidelines in the Linux kernel source for a rationale. 
+
+*** Missing implementation bits
+
+	If you implement a class and you are missing implementation bits,
+	please put in the code the word "TODO" and a description of what
+	is missing to be implemented.
+
+*** Tagging buggy code
+
+	If there is a bug in your implementation tag the problem by using
+	the word "FIXME" in the code, together with a description of the 
+	problem.
+
+	Do not use XXX or obscure descriptions, because otherwise people
+	will not be able to understand what you mean.
+
+*** Tagging Lame specs
+
+	Sometimes the specification will be lame (consider Version.ToString (fieldCount)
+	where there is no way of knowing how many fields are available, making the API
+	not only stupid, but leading to unreliable code).
+
+	In those cases, use the keyword "LAMESPEC".
+
+** Namespaces
+
+	We are using a number of namespaces in the class libraries for
+	private classes when we need them, you are encouraged to use these:
+
+<pre>
+Mono
+ .Languages     // General Compiler classes
+   .CSharp      // Specific C# parsing/tokenizing classes
+   .MonoBASIC   // Specific VB.NET/MonoBASIC parsing/tokenizing classes
+   .Python      // Specific Python parsing/tokenizing classes
+ .Runtime
+   .LateBind    // General latebinding-support for MonoBASIC/Python
+   .MonoBASIC   // Specific runtime classes for MonoBASIC programs
+   .Python      // Specific runtime classes for Python programs
+ .Web
+   .UI
+     .Utils     // Gaurav utility classes
+</pre>
+
+** FAQ
+
+Frequently asked questions about the class library:
+
+Q: I am writing a new class that overrides one of the system classes,
+   and I am getting a 1595 warning from the compiler.  Should we use a
+   different namespace?
+
+A: There is a quick solution to the problem, you can pass the command
+   line argument /nowarn:1595 and this will effectively let you use
+   your implementation of the code, while overriding the ones from the
+   system assemblies.

+* Class Library Documentation
+
+** Summary
+
+	<em>
+	[This documentation is in progress.  Comments to
+	<a href="mailto:jbarn@httcb.net">jbarn@httcb.net</a>.]
+	</em>
+	
+	While using inline XML tags to document classes is certainly
+	convenient, properly verbose documentation quickly overwhelms
+	the code, making the source quite difficult to read.  Furthermore,
+	multilingual documentation makes for significant additional text.
+	
+	With these considerations in mind, Mono will use external XML files
+	for type documentation, rather than documenting the source inline.
+	
+	Several tools will be created for managing, verifying, generating,
+	and updating class library documentation, including:
+	
+	<ul>
+		<li><a href="#docstub">docstub</a></li>
+		<li><a href="#docverify">docverify</a></li>
+		<li><a href="#docconv">docconv</a></li>
+		<li><a href="#docgen">docgen</a></li>
+		<li><a href="#monodoc">monodoc</a></li>
+	</ul>
+	
+** XML Documentation Files and Formats
+
+	
+*** Monodoc XML
+	This XML is similar to the XML documentation described in the
+	C# standard, with added tags for internationalization and a
+	slightly different structure.  Documentation and a DTD/Schema
+	for Monodoc XML is forthcoming.
+	
+	Monodoc XML does not contain any definitive type information,
+	and is only useful in conjunction with the Type definition for
+	whatever is being documented.
+	
+	This XML could be generated by hand, by monostub, or by monodoc.
+	
+*** Assembly XML
+	This XML is generated by combining runtime type information for
+	an Assembly with a collection of Monodoc XML files.  The resultant
+	XML (in the best of cases) contains both complete type and
+	documentary information for each type in the assembly.
+	
+	This XML contains enough information to be transformed into
+	user-accessible documentation.  It is likely that scripts
+	will be created to generate reference docs as HTML and other
+	formats.
+	
+	Documentation and a DTD/Schema for Assembly XML is forthcoming.
+	
+** Documentation Tools
+
+*** <a name="docstub">docstub</a>
+	Given a type name and an assembly, generates stub Monodoc XML
+	documentation for the type.  Optionally, docstub can attempt to
+	populate initial documentation from an XML file in the format
+	published along with the ECMA standard.
+	
+*** <a name="docverify">docverify</a>
+	Given a Monodoc XML file and an assembly, verifies that the
+	documentation matches the compiled type.  Checks signatures,
+	parameters, et cetera.
+	
+*** <a name="docconv">docconv</a>
+	Converts from Monodoc XML to the standard C# compiler-emitted
+	XML format and vice versa.
+	
+*** <a name="docgen">docgen</a>
+	Given an assembly and a collection of Monodoc XML files, creates
+	an Assembly XML file containing all documentation and type information
+	available.  This output is suitable for transforming into user
+	documentation.
+	
+*** <a name="monodoc">monodoc</a>
+	A GUI tool for documentation and translation, this encapsulates
+	the capabilities of docstub, docverify, docconv, and docgen in
+	a friendly user interface.  In addition, monodoc provides features
+	to ease translation, such as side-by-side editing and coverage
+	statistics.
+	
+** Status and Roadmap
+
+*** 2 January 2002
+
+	As I write the initial version of this document, very little has been
+	implemented.  Currently, there is a:
+	
+	<ul>
+	<li>Preliminary version of the Monodoc XML format</li>
+	<li>Preliminary version of the docstub utility</li>
+	</ul>
+	
+	Here's hoping for frequent, productive updates.
+

+* Contributing to the Mono project
+
+	There are many ways in which you can help in the Mono project:
+
+	<ul>
+		* <b>Programmers:</b> You can work on a free
+		  implementation of the <a
+		  href="class-library.html">class libraries</a>, the
+		  <a href="runtime.html">runtime engine</a>, <a
+		  href="tools.html">the tools</a>, the <a

+
+		* <b>Writers:</b> You can help us bywriting <a
+		  href="documentation.html">documentation</a>.
+	</ul>
+
+	Those are just broad things that need to be worked on, but
+	something that would help tremendously would be to help with
+	small duties in the project that need to be addressed. 
+
+	You can see what needs to be done in the class libraries <a href="class-status.html">here</a>
+
+* IRC Channel
+
+	Many developers get together on the <b>#mono</b> irc channel
+	on the <b>irc.gnome.org</b> server.  
+
+** To start contributing
+
+	As a programmer, you can contribute in three different scenarios to Mono:
+
+	<ul>
+		* If you only have Linux/Unix.
+		* If you only have Windows.
+
+		* If you have both Linux and Windows.
+	</ul>
+
+	You might also want to check our <a href="#setup">common
+	setups</a> section that describes some common setups that people
+	use while working on Mono.
+
+*** Contributing to the class library, regression tests or the compiler
+
+	This only requires Windows currently.
+
+	To start developing classes or to contribute to the compiler,
+	you only need Windows and the .NET Framework 1.0 SDK.  Please notice
+	that you do not need Visual Studio (although you can use it if
+	you want).  The .NET Framework SDK requires some version of
+	Windows XP or Windows NT.  If you are running Windows 98, 95
+	or Me, you could use instead the <a
+	href="http://msdn.microsoft.com/downloads/default.asp?url=/downloads/sample.asp?url=/msdn-files/027/001/829/msdncompositedoc.xml">.NET Redist package</a>, but it
+	lacks the documentation browser and the ildasm program (C#, VB, JScript and IL 
+	assembler are included).
+
+	You can get it <a href="http://msdn.microsoft.com/downloads/default.asp?url=/downloads/sample.asp?url=/msdn-files/027/000/976/msdncompositedoc.xml&frame=true">here</a>
+
+	If you are new to .NET, writing regression tests is a good way
+	of starting to contribute: it will help you get used to C# as
+	well as getting comfortable with the .NET APIs.  
+
+	This helps because at this point you might be the best
+	qualified person to fix a problem found by the regression
+	test, or you might have a new class to implement in the .NET
+	world that only has a test suite.  
+	
+	To get started writing tests see the <a href="testing.html">Test Suite</a>
+	section. <a href="mono-contribution-howto.html">Here</a> there is a good All-In-One introduction to the art of writing tests.
+
+
+*** Contributing to the runtime engine
+
+	This only requires Linux, currently some tasks are easier if you
+	have access to Windows as well.
+
+	Here are a few things you can do:
+	<ul>
+		* Port the runtime to other architectures.
+		* Port the runtime to other operating systems.
+		* Finish the IL code verifier in the runtime.
+		* Hack the JIT, improve the code generator, add new
+		  pattern rules, improve the register allocator.
+		* Implement the debugging interfaaces
+	</ul>
+
+** Bug reporting
+
+	If you find bugs in Mono, please make sure you enter a bug
+	report so we can keep track of problems in Mono.
+
+	To enter bug reports go to <a href="http://bugzilla.ximian.com">
+	http://bugzilla.ximian.com</a> and enter bug reports against
+	your favorite component (Mono, Runtime, C# compiler).
+
+	You can review the list of current bugs by going <a href="http://bugzilla.ximian.com/buglist.cgi?product=Mono%2FClass+Libraries&product=Mono%2FMCS&product=Mono%2FRuntime&bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&email1=&emailtype1=substring&emailassigned_to1=1&email2=&emailtype2=substring&emailreporter2=1&changedin=&chfieldfrom=&chfieldto=Now&chfieldvalue=&short_desc=&short_desc_type=substring&long_desc=&long_desc_type=substring&bug_file_loc=&bug_file_loc_type=substring&keywords=&keywords_type=anywords&op_sys_details=&op_sys_details_type=substring&version_details=&version_details_type=substring&cmdtype=doit&order=%27Importance%27&form_name=query">here</a>

+	A few smaller tasks are here, dropped in no particular order:
+	<ul>
+		* <b>Mono/doc and web site:</b> They need to be
+		  packaged up in the official `distribution'
+
+		* Adding serialization support to all the classes.
+

+* Common Setups
+
+	People running both Linux and Windows while contributing to
+	Mono use a number of tricks to increase their productivity.
+
+	Scenarios:
+
+	<ul>
+		* <b>Linux host and Windows host</b>
+
+		  The Windows file system is shared (right click on
+		  your hard drive icon, and select sharing, allow this
+		  to be shared).  
+
+		  The Windows machine has the required build tools
+		  (cygwin, and the .NET framework).  On the Windows
+		  machine, you want to setup the ssh server (run the
+		  ssh-host-config program to configure your ssh) and
+		  run it (from a cygwin terminal, type: /usr/sbin/sshd).
+
+		  From the Linux side, you want to mount the Windows
+		  file system, using something like this:
+
+<tt><pre>
+	mount -t smbfs -o uid=miguel,username="Miguel de Icaza" "//quack/c$" /mnt
+</pre></tt>
+
+		  In the above example, my Linux user name is
+		  `miguel', and this will allow this user to have
+		  read/write access to the share.  
+
+		  The host name is `quack', and the name of the share
+		  is `c$' (that is the C: partition).  
+
+		  The file system is accessible on /mnt.
+
+		  You can perform your cvs update and cvs commits from
+		  the /mnt directory, and run Emacs or your favorite
+		  Linux text editor on the Unix side in this way.
+
+		  Then from another terminal, you can ssh into your
+		  Windows box using ssh, like this: ssh "Miguel de Icaza@quack"
+	</ul>
+
+* Special Note
+
+	If you have looked at Microsoft's implementation of .NET or
+	their shared source code, you may not be able to contribute
+	to Mono.  Details will follow when we know more about this.
+
+	In general be careful when you are implementing free software
+	and you have access to proprietary code.  We need to make sure
+	that we are not using someone else's copyrighted code
+	accidentally. 
+
+	Please do not use the <b>ildasm</b> program to disassemble
+	proprietary code when you are planning to reimplement a class
+	for Mono.  If you have done this, we might not be able to use
+	your code.
+
+	Please stick to published documentation for implementing any
+	classes.

+* Developer FAQ
+
+** New classes
+
+Q: Should we write classes which are not part of the .NET or ECMA specs?
+
+A: Yes.  The ECMA and .NET specifications are far from complete, and
+   to produce a complete platform we will need a number of other
+   classes and components.
+
+   Any new classes that are not part of .NET or ECMA should be
+   designed to be reusable on anyone's CLI implementation.  So that
+   Windows developers can also use any new classes that we come up
+   with.
+
+   We have a few existing <a href="ideas.html">Ideas on missing
+   classes</a> 
+
+** Language Compatibility
+
+Q: What is the magic that allow multiple languages to co-exist?
+
+A: From Fergus Henderson:
+
+<i><blockquote>
+There are different levels of interoperability.
+The ECMA spec defines different categories of
+CLS (Common Language Specification) conformance.
+There are also some useful categories that don't
+correspond to any of the levels defined in the ECMA spec.
+In increasing degree of difficulty, your language implementation
+can
+
+	<ul>
+	* (a) just generate IL
+
+	* (b) be a CLS "consumer", which means that it can read in
+	  meta-data describing component interfaces,
+	  and that it provides a way to declare variables of
+	  CLS-complaint types and to call CLS-complaint methods.
+
+	* (c) be a CLS "extender", which means that it can in addition
+	  derive from CLS-compliant classes
+	  and implement CLS-compliant interfaces
+
+	* (d) be able to produce components with *any* CLS-compliant
+	component interface.
+	</ul>
+
+Supporting some of these may require extending your language.  However,
+you can get quite a lot of interoperability by just putting appropriate
+functionality in your compiler, without extending your language.
+
+For some things, e.g. ASP.NET, your language implementation also needs to be
+able to
+
+	<ul>
+	* (e) consume CodeDom trees.  CodeDom trees are an abstract
+	representation of programs in a form similar to a C# parse
+	tree, with embedded code snippets (unparsed strings).
+	Given a CodeDom tree, with the snippets in your language,
+	your language implementation needs to generate a (i) .NET
+	assembly and possibly also (ii) a source file in your language.
+
+	* (f) produce CodeDom trees.  For some applications,
+	your language implementation also needs to be able to
+	round-trip from CodeDom -> your language -> CodeDom.
+	</ul>
+
+and for some things it needs to
+
+	<ul>
+	* (g) generate *verifiable* IL
+	</ul>
+
+So when you hear all the hype about how language XYZ is a
+".NET language", make sure you ask which of these different
+things are supported.
+
+[For the record, Mercury currently supports (a).  We're working on
+(b) and (g), and on parts of (c) and (e).  We're never going to do (f), I very
+strongly doubt we'll ever do (d), and for (c) we might only ever support
+implementing interfaces, not deriving from classes.]
+
+</blockquote></i>
+
+** PInvoke 
+
+Q: What are the two major initiatives to implement PInvoke?
+
+A: Fergus Henderson answers:
+
+<i><blockquote>
+Many of the .NET APIs will need to be implemented using code that calls C/Unix
+APIs, such as stat().  The standard way of interfacing with native code from
+.NET code is to use "PInvoke".  However, there is a difficulty: many of
+these APIs are defined in terms of types such as C's `long' or `size_t'
+or the Posix `struct stat' whose representation varies depending on the
+platform (architecture/OS/C compiler).  There's no *portable* way of
+accessing those from .NET managed code.
+
+So, there are a couple of different approaches.
+One possibility is to access such routines by writing a wrapper, e.g. in C,
+that provides the same functionality without using types with a system-dependent
+representation.  The wrapper can then be directly accessed from portable
+.NET code.  The .NET code remains both source- and binary-portable;
+the wrapper code is source-portable, but needs to be compiled
+seperately for each target platform.  The drawback of this approach is
+that you have to write a lot of cumbersome wrapper code.
+
+Another possibility is to extend the .NET VM with support for an
+additional custom attribute, e.g. "[PosixType]".  The VM would then
+represent types tagged with this attribute in the same way that the
+underlying system represents those types.  With this approach, no
+wrapper code would be needed.  A drawback of this approach is that it
+pushes quite a bit of complexity into the VM; the VM would have to know
+the native representation of all types annotated with this attribute.
+Another drawback is that code using this extension might not work on
+different VMs.
+
+There have also been some other suggestions, but those are the two that
+I think are the best.
+</blockquote></i>
+
+Q: What is the problem implementing PInvoke?
+
+A: Again, from Fergus Henderson:
+
+<i><blockquote>
+There's no problem implementing PInvoke as specified in the ECMA
+specs and/or MS documentation.  It's just that PInvoke by itself
+doesn't solve all of the problems; in particular it doesn't solve
+the problem of C types whose representation is different on different
+systems.
+</blockquote></i>
+
+** CVS use
+
+Q: Why do we keep ChangeLogs and make the CVS commit messages be the
+   same?  One could be generated from the other
+
+A: There are a number of reasons for keeping ChangeLog files as well as
+   CVS commit files:
+
+   <ul>
+	* Offline programming: when people are traveling, CVS logs are
+          not available.
+
+	* Slow CVS access: Many people work over modem lines (very
+          typical for contributors in Europe, Asia, Latin America)
+          using CVS is slow and might not be available to you (cvs
+          server down, no anoncvs server available).
+
+	* ChangeLogs travel in a released tarball package, so it is
+	  possible to study the rationale of changes even after a
+	  project is long "released", or you only have the sources for
+	  the code. 
+
+	* ChangeLog are not metadata for each file, they are live
+          files that you can browse in the package that is being
+          distributed. 
+   </ul>
+
+Making the CVS commit message be the same as the ChangeLog has other
+benefits:
+
+   <ul>
+	* You can track down with `cvs log' what things were changed,
+          and match those to meaningful reports on the intentions of
+          the commit.
+
+	* When reading the commits-list, you can get a glimpse of the
+          changes without having to diff out or cvs update your tree.
+
+	* You can read off-line the changes that are being made
+          (asyncrouns operation).
+   </ul>
+
+This mechanism works very well for GNOME and other projects.
+
+Q: Should I use any of the special RCS keywords like $Id: devel-faq,v 1.1 2001/07/31 21:13:05 miguel Exp $, $Author: miguel $,
+   $Date: 2001/07/31 21:13:05 $, or $Revision: 1.1 $?
+
+A: Please avoid using those in the source code in the CVS.  They
+   are not really useful, and they cause a lot of conflicts when
+   people have separate CVS trees.
+
+   It was a nightmare with the Linux kernel when two people had their
+   private CVS trees and were submitting patches to the core.

+* Documentation
+
+	Although most of the concepts from Microsoft.NET can
+	be applied to the completed Mono platform, we do need to
+	have a complete set of free documentation written specifically
+	for Mono.
+
+	The documentation license we have chosen is the GNU Free
+	Documentation License (FDL), the standard for most documents
+	in the free software world. 
+
+	We need documentation on a number of topics:
+
+	<ul>
+
+		* The development tools (compilers, assembler tools,
+		  language reference, design time features).
+
+		* Frequently Asked Question compilations.
+
+		* HOWTO documents.
+
+		* The Class Libraries
+
+		* Tutorials on Mono and the specifics of running it. 
+
+		* A guide to Mono as compared to the Microsoft.NET
+		  Framework SDK
+
+	</ul>
+
+** Class Library documentation
+
+	We are moving to a new setup for documenting the class libraries, 
+	and you can read about it <a href="classlib-doc.html">here</a>.
+
+        A few words of warning and advice for class documentors:
+
+        A well-documented API can ease hours of frustration; as Mono
+        matures, robust and complete class library documentation will
+        become increasingly important.  As you write API documentation,
+        whether it is embedded in source files or in external Monodoc XML,
+        please keep the following in mind:
+
+        Plagarism, even if it's unintentional, is a Bad Thing(TM).
+        Microsoft's .NET Framework Class Library documentation is an
+        excellent resource for understanding the behavior and properties of
+        a type, and a lot of hard work went in to creating this (copyrighted)
+        resource.  Please don't copy from Microsoft's reference when
+        documenting a type.
+
+        To avoid this, I (<a href="mailto:jbarn@httcb.net">jbarn@httcb.net</a>)
+        suggest that you read the complete Microsoft documentation for a type,
+        ponder it for a while, and write the Mono documentation in your own
+        words.  While it's certainly okay to refer to the Microsoft
+        documentation to clarify your understanding of behavior or properties,
+        please don't open the Microsoft docs and refer to them for each member
+        you document.
+
+        There's a lot of domain expertise among the class library contributors;
+        let's put the same personal stamp on the class library documentation
+        that we have on the class libraries themselves.

+	SDK</strong>, <strong>GLIB 2.0</strong> and 
+	<strong>pkg-config</strong>.  
+
+        When installing Cygwin, don't forget to include

+	These scripts automate the installation of GLIB and pkgconfig
+	(building from source on Unix, and using binary packages

+	the script, follow these simple steps:
+
+	<ul>
+		* Save the script for your platform somewhere (e.g. /usr/local/bin)
+		* Make the script executable (i.e chmod 755 /usr/local/bin/mono-build.sh)
+		* Create a directory to hold the mono source, and the compiled binaries (e.g. mkdir ~/mono)
+		* Change to the new directory (i.e. cd ~/mono)
+		* run the script (i.e. /usr/local/bin/mono-build.sh)
+	</ul>
+
+	The script requires wget on either platform, and building the
+	software requires make, gcc, automake, autoconf, and libtool.
+	You should install these packages from your distribution or
+	with the cygwin installer.
+
+	The script will download required packages from
+	www.go-mono.com and do a cvs checkout of mono in the current

+** Basics
+
+Q: What is Mono exactly?
+
+A: The Mono Project is an open development initiative sponsored by
+   Ximian that is working to develop an open source, Unix
+   version of the Microsoft .NET development platform.  Its objective
+   is to enable Unix developers to build and
+   deploy cross-platform .NET Applications.  The project will
+   implement various technologies developed by Microsoft that have now
+   been submitted to the ECMA for standardization.
+
+Q: What is the difference between Mono and the .NET Initiative?
+
+A: The ".NET Initiative" is a somewhat nebulous company-wide effort by
+   Microsoft, one part of which is a cross-platform development
+   framework.  Mono is an implementation of the development framework,
+   but not an implementation of anything else related to the .NET
+   Initiative, such as Passport, software-as-a-service, or
+   corporate rebranding.
+
+Q: What technologies are included in Mono?
+
+A: Mono contains a number of components useful for building new
+   software:
+
+	<ul>
+		* A Common Language Infrastructure (CLI) virtual
+		  machine that contains a class loader, Just-in-time
+		  compiler, and a garbage collecting runtime.
+
+		* A class library that can work with any language
+		  which works on the CLR.
+
+		* A compiler for the C# language.  In the future we
+		  might work on other compilers that target the Common
+		  Language Runtime.
+	</ul>
+
+
+   Windows has compilers that target the virtual machine from <a
+   href="http://msdn.microsoft.com/net/thirdparty/default.asp#lang">a
+   number of languages:</a> Managed C++, Java Script, Eiffel,
+   Component Pascal, APL, Cobol, Oberon, Perl, Python, Scheme,
+   Smalltalk, Standard ML, Haskell, Mercury and Oberon.
+
+   The CLR and the Common Type System (CTS) enables applications and
+   libraries to be written in a collection of different languages that
+   target the byte code
+
+   This means for example that if you define a class to do algebraic
+   manipulation in C#, that class can be reused from any other
+   language that supports the CLI.  You could create a class in C#,
+   subclass it in C++ and instantiate it in an Eiffel program. 
+
+   A single object system, threading system, class libraries, and
+   garbage collection system can be shared across all these languages.
+   
+Q: Where can I find the specification for these technologies?
+
+A: You can find the work-in-progress documentation from the T3G ECMA
+   group here:
+ 
+   <a href="http://www.dotnetexperts.com">http://www.dotnetexperts.com</a>
+
+Q: Will you implement the .NET Framework SDK class libraries?
+
+A: Yes, we will be implementing the APIs of the .NET Framework SDK
+   class libraries. 
+
+Q: Will you offer an ECMA-compliant set of class libraries?
+
+A: Eventually we will.  Our current focus is on interoperating
+   with the Microsoft SDK, but we will also offer an ECMA compliant
+   set of libraries. 
+
+Q: What does the name "Mono" mean?
+
+A: Mono is the word for `monkey' in Spanish. We like monkeys.
+
+Q: Is Mono usable?
+
+A: The JIT engine is usable on Intel x86 machines.  An interpreter
+   can be used on other non-Intel x86 machines.  
+
+   The class libraries are mature enough to run some real applications
+   (the compiler for instance, and every day more and more applications
+   are natively developed with Mono).
+
+Q: When will you ship it?
+
+A: Different parts of Mono will achieve usability at different stages,
+   once we are comfortable with the compiler, we will release "Mono Core",
+   which contains everything needed to develop applications with the base
+   class libraries.  This should be available at some point during 2002.
+
+   Other higher level class libraries (ASP.NET, ADO.NET, Windows.Forms) will
+   be released when they become stable. 
+
+Q: What major components will you include in Mono?
+
+A: Hopefully everything that Microsoft ships on their Framework
+   (ADO.NET, ASP.NET, Windows.Forms), and
+   we encourage third party developers to create reusable components that
+   work on both Mono and Windows.
+
+Q: How can I contribute?
+
+A: Check the <a href="contributing.html">contributing</a> section. 
+
+Q: Aren't you just copying someone else's work?
+
+A: We are interested in providing the best tools for programmers to
+   develop applications for Free Operating Systems.  We also want to help
+   provide the interoperability that will allow those systems to fit in
+   with other standards.
+
+   For more background, read the <a href="http://www.go-mono.com/rationale.html">Mono
+   Project white paper</a>.
+   the project.
+
+Q: Miguel said once that Mono was being implemented in COBOL. Is that true?.
+
+A: No. It was a joke.
+
+

+
+** The Ximian Role in the Mono Project
+
+Q: Why is Ximian working on .NET?
+
+A: Ximian is interested in providing the best tools for programmers to
+   develop applications for Free Operating Systems.  
+
+   For more information, read the project <a
+   href="rationale.html">rationale</a> page.
+
+Q: Will Ximian be able to take on a project of this size?  
+
+A: Of course not. Ximian a supporter of the Mono project, but the only way
+   to implement something of this size is for the entire free software
+   community to get involved. Visit the <a href="contributing.html">contributing</a> 
+   page if you'd like to help out.
+
+Q: What pieces will Ximian be working on?
+
+A: We will devote most of our resources to work on the pieces which are
+   on the critical path to release a development and execution
+   environment. Once the project is at a stage where it is useful in
+   the real world, it will achieve a critical mass of developers to
+   improve it further.
+
+Q: Will Ximian offer Mono commercially?
+
+A: When Mono is ready to be shipped Ximian will offer a commercial
+   support and services for Mono. 
+
+Q: Does Ximian provide consulting services around Mono?
+
+A: Yes, Ximian does provide consulting services around Mono to
+   make it suitable to your needs.  Porting the runtime engine,
+   customizing it, working on specific classes or tuning the code
+   for your particular needs. 
+
+Q: Will you wait until Mono is finished?
+
+A: Mono will ship on various stages as they mature.  Some people
+   require only a subset of the technologies, those will ship first.
+
+   More advanced features will take more time to develop.  A support
+   timeline will be available in June 2002.
+
+<a name="gnome"></a> 
+** Mono and GNOME
+
+Q: How is Mono related to GNOME?
+
+A: In a number of ways.  This project was born out of the need of
+   providing improved tools for the GNOME community, and will use
+   existing components that have been developed for GNOME when they
+   are available.  For example, we plan to use Gtk+ and Libart to
+   implement Winforms and the Drawing2D API and are considering
+   GObject support.
+
+Q: Has the GNOME Foundation or the GNOME team adopted Mono?
+
+A: Mono is too new to be adopted by those groups. We hope that the
+   tools that we will provide will be adopted by free software
+   programmers including the GNOME Foundation members and the GNOME
+   project generally.
+
+Q: Should GNOME programmers switch over to Mono now?
+
+A: It is still far to early for discussions of "switching over."  No
+   pieces of Mono will be ready within the next six months, and a
+   complete implementation is roughly one year away.
+
+   We encourage GNOME developers to continue using the existing tools,
+   libraries and components.  Improvements made to GNOME will have an
+   impact on Mono, as they would be the "backend" for various classes.
+
+Q: Will Mono include compatibility with Bonobo components? What is the
+   relationship between Mono and Bonobo?
+
+A: Yes, we will provide a set of classes for implementing and using
+   Bonobo components from within Mono.  Mono should allow you to write
+   Bonobo components more easily, just like .NET on Windows allows you
+   to export .NET components to COM.
+
+Q: Does Mono depend on GNOME?
+
+A: No, Mono does not depend on GNOME.  We use a few packages produced by
+   the GNOME team like the `glib' library.  
+
+Q: But will I be able to build GNOME applications?
+
+A: Yes, we will enable people to write GNOME applications using Mono.
+
+<a name="gui"></a>
+** GUI applications
+
+Q: Will Mono enable GUI applications to be authored?
+
+A: Yes, you will be able to build GUI applications.  Indeed, that is our
+   main focus.  We will provide both the Windows.Forms API and the Gtk# API.
+
+Q: What is the difference between Gtk# and System.Windows.Forms?
+
+A: Gtk# is a set of bindings for the Gtk+ toolkit for C# (and other
+   CIL-enabled languages).  System.Windows.Forms is an API defined
+   by Microsoft to build GUI applications.
+
+Q: Will I be able to run my smart clients on systems powered by Mono?
+
+A: As long as your applications are 100% .NET and do not make use
+   of P/Invoke to call Win32 functions, your smart client applications
+   will run on Mono platforms.
+
+Q: Where can I learn mora about Gtk#?
+
+A: The following <a href="http://gtk-sharp.sourceforge.net>link</a> sends you to the page of the project.
+
+Q: What can I do with Gtk#?. 
+
+A: Gtk# is becoming very usable and you can create applications and
+   applets like those you see in a GNOME desktop environment. It's 
+   easy to install so it's worth a try. 
+
+Q: How can I compile my HelloWorld.cs which uses Gtk#?.
+
+A: Try: mcs --unsafe -o HelloWorld.exe -r glib-sharp -r pango-sharp -r
+        atk-sharp -r gdk-sharp -r gtk-sharp -r gdk-imaging-sharp
+        HelloWorld.cs
+
+<a name="winforms"></a>
+** Mono and WinForms
+
+Q: Can you tell me why aren't you implementing WinForms?. 
+
+A: (This is based in an original mail to mono-list written by Miguel de
+   Icaza. You should read it for completion, but the core part is here).
+   
+   First, Windows.Forms is packed with quirks and is not that great of a 
+   toolkit in the first place. Up to the point of the unconfirmed rumor 
+   that Microsoft is working on a replacement for it. 
+
+   Once the runtime is done, we will very likely start contributing to
+   the Gtk# project ourselves, and we will likely start doing feasibility
+   work on getting Mono used by Gnome developers: full gnome apps and
+   extending existing applications.
+
+   Those interested in hacking on Windows.Forms are welcome to do so,
+   but Ximian will not likely look at it in the near future; if there is
+   enough demand, or I can be convinced that Windows.Forms is useful for
+   something Ximian might re-evaluate our resource allocation for this
+   task.
+
+   By doing native ports, we could use the same API on all those systems. 
+   Also, Gtk is mature enough, we know this because we have built an entire
+   desktop (and all sorts of very window system-specific hacks), and we
+   have built a bunch of productivity applications with it. 
+
+Q: What about VCL?.
+
+   Someone mentioned VCL. The only problem with the VCL is that it can
+   only be used for GPL applications (or I guess you could license it from
+   Borland for your app), and would have to be ported from Delphi to C# 
+   (or someone would have to write a CIL compiler for it).
+
+Q: What about doing something like the eclipse project (www.eclipse.org)? 
+
+A: The Eclipse toolkit is not a general purpose toolkit.  It will require a
+   lot of work before it is such a thing.  It is a toolkit used to
+   implement a development environment.
+
+
+<a name="msft"></a>
+** Mono and Microsoft
+
+Q: Is Microsoft helping Ximian with this project?
+
+A: No. Ximian CTO Miguel de Icaza had a friendly conversation with
+   Microsoft software architect David Stutz, but that's about the
+   extent of the contact. Microsoft is interested in other
+   implementations of .NET and are willing to help make the ECMA spec
+   more accurate for this purpose.
+
+   Ximian representatives have also spoken with Sam Ruby at the ECMA
+   TG3 committee to discuss the same issues.
+
+Q: Is Microsoft or Corel paying Ximian to do this?
+
+A: No.
+
+Q: Do you fear that Microsoft will change the spec and render Mono
+   useless?
+
+A: No.  Microsoft proved with the CLI and the C# language that it was
+   possible to create a powerful foundation for many languages to
+   interoperate.  We will always have that.  
+
+   Even if changes happened in the platform which were undocumented,
+   the existing platform would a value on its own.
+
+Q: Are you writing Mono from the ECMA specs?
+
+A: Yes, we are writing them from the ECMA specs and the published
+   materials in print about .NET.
+
+Q: If my applications use Mono, will I have to pay a service fee?
+
+A: No.  Mono is not related to Microsoft's initiative of
+   software-as-a-service.
+
+Q: Is the Mono Project is related to the Microsoft Hailstorm effort?  Is
+   Ximian endorsing Hailstorm?  
+
+A: No.  The Mono Project is focused on providing a compatible set of
+   tools for the Microsoft .NET development platform.  It does not
+   address, require, or otherwise endorse the MS Passport-based
+   Hailstorm single sign-on system that is part of Windows XP and
+   other services.
+
+Q: Will Mono or .NET applications depend on Microsoft Passport?
+
+A: No. MS Passport is unrelated to running .NET compatible applications
+   produced with the Mono tools.  The only thing you will need is a
+   just-in-time compiler (JIT).
+
+Q: What is a 100% .NET application?
+
+A: A `100% .NET application' is one that only uses the APIs defined
+   under the System namespace and does not use PInvoke.  These
+   applications would in theory run unmodified on Windows, Linux,
+   HP-UX, Solaris, MacOS X and others. 
+
+Q: If Microsoft will release a port of their .NET platform under the
+   `Shared Source' license, why should I bother with anything else?
+
+A: The Shared Source implementation will be expensive and its uses
+   will be tightly restricted, especially for commercial use. We are
+   working towards an implementation that will grant a number of
+   important rights to recipients: use for any purpose,
+   redistribution, modification, and redistribution of modifications.
+
+   This is what we call <a
+   href="http://www.gnu.org/philosophy/free-sw.html">Free Software</a>
+
+Q: Is Mono a free implementation of Passport?
+
+A: No. Mono is just a runtime, a compiler and a set of class
+   libraries.
+
+Q: Will the System.Web.Security.PassportIdentity class mean
+   that my software will depend on Passport?
+   
+A: No.  Applications may use that API to contact a Passport site, but
+   are not required to do so.
+
+   As long as your application does not use Passport, you will not
+   need Passport.  
+
+Q: Will Mono running on Linux make Passport available for Linux?
+
+A: No.  However, the Passport toolkit for Linux-based web servers is
+   available from Microsoft.
+
+Q: Will Mono allow me to run Microsoft Office on Linux?
+
+A: No, it will not.  Microsoft Office is a Windows application.  To
+   learn more about running Windows applications on Intel Unix systems
+   refer to <a href="http://www.winehq.com">the Wine Project</a>.
+
+<a name="pnpproject"></a>
+** Mono and Portable.NET
+
+Q: What are the differences between Mono and Portable.NET?
+
+A: Most of Mono is being written using C#, with only
+   a few parts written in C (The JIT engine, the runtime, the
+   interfaces to the garbage collection system).  
+
+   It is easier to describe what is unique about Mono:
+   <ul>
+     <li> A self-hosting C# compiler written in C#, which is clean, easy
+          to maintain.
+
+     <li> A multi-platform runtime engine: both a JIT engine and an
+          interpreter exist.  The JIT engine runs currently on x86
+          systems, while the interpreter works on Sparc, StrongARM and
+          PowerPC systems.  
+
+     <li> Supports Linux, Windows and Solaris at this point.
+
+     <li> The JIT engine is written using a portable instruction
+          selector which not only generates good code (we are told
+          that we are faster than Rotor, but it is hard to tell) but
+          is also the foundation to retarget the JIT engine to other
+          systems.  
+
+          The system employed is described in various compiler
+          books and it is very similar to what is described in the 
+          book that covers LCC, the Ansi C retargetable C compiler.
+
+     <li> The JIT engine supports inlining, constant folding and propagation,
+
+     <li> Full support for remoting in the runtime, but the class 
+          libraries are still behind.
+
+     <li> The C# compiler, the JIT engine and the class libraries are
+          mature enough that the whole system is self-hosting, ie, that
+          it can be fully developed with itself at this point.
+
+     <li> We are not yet done, and there is a lot of work left to be
+          done
+
+     <li> We have a great community of developers, without which Mono
+          would not be possible.
+
+     <li> We will provide an ahead of time compilation mode in the 
+          future.
+   </ul>
+
+<a name="webservices"></a>
+** Web Services
+
+Q: How is Mono related to Web Services?
+
+A: Mono is only related to Web Services in that it will implement the
+   same set of classes that have been authored in the .NET Framework
+   to simplify and streamline the process of building Web Services.
+
+   But most importantly, Mono is an Open Source implementation of the
+   .NET Framework.
+
+Q: Can I author Web Services with Mono?
+
+A: You will be able to write Web Services on .NET that run on Mono and
+   viceversa. 
+
+Q: If Mono implements the SDK classes, will I be able to write and
+   execute .NET Web Services with it?
+   
+A: Yes.  When the project is finished, you will be able to use the
+   same technologies that are available through the .NET Framework SDK
+   on Windows to write Web Services.
+
+Q: What about Soup?  Can I use Soup without Mono?
+
+A: Soup is a library for GNOME applications to create SOAP servers and
+   SOAP clients, and can be used without Mono.  You can browse the
+   source code for soup using <a
+   href="http://cvs.gnome.org/bonsai">GNOME's Bonsai</a>.
+
+Q: Can I use CORBA?
+
+A: Yes. The CLI contains enough information about a class that
+   exposing it to other RPC systems (like CORBA) is really simple, and
+   does not even require support from an object.  
+
+   We will be implementing CORBA interoperation as an extension to the
+   Mono classes so that we can integrate with Bonobo, just like
+   Microsoft provides COM interoperation classes and support
+   mechanisms. 
+
+Q: Can I serialize my objects to other things other than XML?
+
+A: Yes, although the serializing tools have not yet been planned, and
+you would probably have to implement them yourself.
+
+Q: Will Mono use ORBit?
+
+A: No. Mono will be using a new implementation of CORBA that isn't still started.

+** Development Tools and Issues
+
+Q: Will it be possible to use the CLI features without using bytecodes
+   or the JIT?
+
+A: Yes. The CLI engine will be made available as a shared library.
+   The garbage collection engine, the threading abstraction, the
+   object system, the dynamic type code system and the JIT will be
+   available for C developers to integreate with their applications if
+   they wish to do so. 
+
+Q: Will you have new development tools?
+
+A: With any luck, Free Software enthusiasts will contribute tools to
+   improve the developer environment.  These tools could be developed
+   initially using the Microsoft implementation of the CLI and then
+   executed later with Mono.
+
+Q: What kind of rules make the Common Intermediate Language useful for
+   JITers?
+
+A: The main rule is that the stack in the CLI is not a general purpose
+   stack.   You are not allowed to use it for other purposes than
+   computing values and passing arguments to functions or return
+   values.  
+
+   At any given call or return instruction, the types on the stack
+   have to be the same independently of the flow of execution of your
+   code. 
+
+Q: Is it true that the CIL is ideal for JITing and not efficient for
+   interpreters?
+
+A: The CIL is better suited to be JITed than JVM byte codes, but you
+   can interpret them as trivially as you can interpret JVM byte
+   codes. 
+
+Q: Isn't it a little bit confusing to have the name of "XSP" (the same 
+   as in the Apache Project) for the ASP.NET support in Mono?.
+
+A: In Mono, xsp is just the name of the C# code generator for ASP.NET 
+   pages. In the Apache Project, it is a term for the "eXtensible Server 
+   Pages" technology so as they are very different things, they don't 
+   conflict.
+
+Q: What about using something like Jabber instead of the System.Messaging 
+   namespace?.
+
+A: In short, MSMQ is not something like Jabber, but asynchronous messaging 
+   through queues. Usefull queues do more than serialize messages, they are 
+   also platform bridges.
+
+Q: Are you supporting XMLDocument and relatives?.
+
+A: Currently, we aren't implementing them yet. It would require updates to 
+   most of the XmlNode derivatives so it's not a trivial task. We are 
+   currently focusing on getting XPath support working. 
+
+Q: Is there any plan to develop an aspx server for Mono?.
+
+A: The webserver turned out to be very simple compared to the rest of the 
+   work. Gonzalo has got the page generator mostly done (a module called 
+   xsp, who has nothing to do with the XSP term used in the Apache Project).
+   Patrik has done a lot of the work to get the ProcessRequest to work.
+   You can try to help in the final touches to the System.Web classes and
+   writing regression tests for the widgets we have.
+
+Q: Is there any way I can develop the class libraries using linux yet?
+
+A: Yes. Some class libraries can be developed on Linux. Search for
+   Paolo's post (he lists which classes can be compiled fine now).
+
+Q: Is there any way I can install a known working copy of mono in /usr, 
+   and an experimental copy somewhere else, and have both copies use 
+   their own libraries? (I'm still not very good at library paths in 
+   linux)
+
+A: Yes. Just use two installation prefixes.
+
+
+<a name="asp">
+** Mono and ASP.NET
+
+Q: Is Mono supporting ASP.NET?
+
+A: Yes. The development of the support for ASP.NET comes in various stages, 
+   here is what Gonzalo has been working on: 1. The Parser. 2. Getting the 
+   parser to generate output compatible with ASP.NET. 3. Running the sample 
+   output with the real Microsoft runtime but using our generated page. 4. 
+   Running the sample with our classes with the .NET runtime. 5. Running 
+   our sample code with our classes with our runtime. This is the process 
+   we are following. Currently Gonzalo has reached point 5.
+
+<a name="java">
+** Mono and Java
+   
+Q: Why don't you use Java?  After all, there are many languages that
+   target the Java VM.
+
+A: You can get very good tools for doing Java development on free
+   systems right now.  <a href="http://www.redhat.com">Red Hat</a> has
+   contributed a <a href="http://gcc.gnu.org">GCC</a> <a
+   href="http://gcc.gnu.org/java">frontend for Java</a> that can take
+   Java sources or Java byte codes and generate native executables; <a
+   href="http://www.transvirtual.com">Transvirtual</a> has implemented
+   <a href="http://www.kaffe.org">Kaffe</a> a JIT engine for Java;
+   Intel also has a Java VM called <a
+   href="http://www.intel.com/research/mrl/orp">ORP</a>.
+
+   The JVM is not designed to be a general purpose virtual machine.
+   The Common Intermediate Language (CIL), on the other hand, is
+   designed to be a target for a
+   wide variety of programming languages, and has a set of rules
+   designed to be optimal for JITers.
+
+Q: Could Java target the CLI?
+
+A: Yes, Java could target the CLI.  We have details on a <a
+   href="ideas.html#guavac">project</a> that someone could take on to
+   make this happen.  
+
+   Microsoft has an implemenation of the Java language called J# that
+   can target the CIL execution engine. 
+
+Q: Is it possible to write a JVM byte code to CIL convertor?
+
+A: Yes, it is possible.  Here are a few starting point:
+
+	<ul>
+        	* A byte code representation is really a flattened forest of
+          	  trees.  Look at the Mono JIT engine to see how we compute
+          	  the basic blocks (this is used to figure out the "trees").
+
+          	  The forest is just an array of trees.
+
+          	  Indeed, run the JIT engine with -d (mono -d prog.exe) and
+          	  you will see how these trees look like.
+
+            	  You will have to do something similar for Java.
+
+        	* Each "forest of trees" has a meaning.  This meaning can now
+          	  be translated into the equivalent "meaning" in CLR-land.
+	</ul>
+
+Q: Could mono become a hybrid cil/java platform?
+
+A: No. It is quite far from the philosophy of the project. The idea of Mono 
+   is, to have only _one_ VM, on which all can run. And if there existing a 
+   binary-converter from Java-.class to IL and if there existing something 
+   like J-Sharp on Mono, you can write programs in Java, which than can run 
+   on Mono. You do not need two bindings (like your example: GTK-Sharp _and_ 
+   Java-Gnome). You need only _one_ of it (GTK-Sharp). Thats the idea of Mono.
+   An other point is, that there are no people, who use OpenSource-JVMs. They 
+   all prefer Suns original. But for Unix there don't exist a .NET-Framework. 
+   So it is possible, that in the future Mono is the standard .NET for unixes.
+
+<a name="extending"></a>
+** Extending Mono
+
+Q: Would you allow other classes other than those in the
+   specification?
+
+A: Yes.  The Microsoft class collection is very big, but it is by no
+   means complete.  It would be nice to have a port of `Camel' (the
+   Mail API used by Evolution inspired by Java Mail) for Mono
+   applications.  
+
+   You might also want to look into implementing CORBA for Mono.  Not
+   only because it would be useful, but because it sounds like a fun
+   thing to do, given the fact that the CLI is such a type rich
+   system. 
+
+   For more information on extending Mono, see our <a
+   href="ideas.html">ideas</a> page.
+
+Q: Do you plan to Embrace and Extend .NET?
+
+A: Embracing a good technology is good.  Extending technologies in
+   incompatible ways is bad for the users, so we do not plan on 
+   extending the technologies.
+
+   If you have innovative ideas, and want to create new classes, we 
+   encourage you to make those classes operate correctly well in both
+   Mono and .NET.
+
+Q: Is there any way I can develop the class libraries using linux yet?
+
+A: Yes. Some class libraries can be developed on Linux. Search for
+   Paolo's post (he lists which classes can be compiled fine now).
+
+Q: Is there any way I can install a known working copy of mono in /usr, 
+   and an experimental copy somewhere else, and have both copies use 
+   their own libraries? (I'm still not very good at library paths in 
+   linux)
+
+A: Yes. Just use two installation prefixes.
+
+
+<a name="portability"></a>
+** Portability
+
+Q: Will Mono only work on Linux?
+
+A: Currently, we are doing our work on Linux-based systems and
+   Windows.  We do not expect many Linux-isms in the code, so it
+   should be easy to port Mono to other UNIX variants.   
+
+Q: What about Mono on non Linux-based systems?
+
+A: Our main intention at Ximian is to be able to develop GNOME
+   applications with Mono, but if you are interested in providing a
+   port of the Winform classes to other platforms (frame buffer or
+   MacOS X for example), we would gladly integrate them, as long
+   they are under an open source license.  
+
+Q: What operating systems/CPUs do you support
+
+A: Mono currently runs on Linux, Windows, Solaris and FreeBSD.
+   There is a JIT engine available for x86 processors that can
+   generate code and optimizations tailored for a particular CPU.
+
+   Interpreters exist for the SPARC, PowerPC and StrongARM cpus.
+
+Q: Does Mono run on Windows?
+
+A: Yes.   The Compiler and the runtime both run on Windows.
+
+Q: When will mono and mcs compile on Linux?.
+
+A: That happend a long time ago. Know you can download and compile 
+   them or even install them from already made binary packages for 
+   Windows and for Linux (RPM/DEB).
+
+Q: Will I require Cygwin to run mono?
+
+A: No.  While you'll need it to compile it, it runs without cygwin and does not even require cygwin1.dll
+
+Q: Will Mono depend on GNOME?
+
+A: It will depend only if you are using a particular assembly (for
+   example, for doing GUI applications).  If you are just interested
+   in Mono for implementing a `Hello World Enterprise P2P Web
+   Service', you will not need any GNOME components.
+
+Q: Is anyone working on porting Mono to IA-64?
+
+A: Nobody is working on such port.
+
+Q: If I were about to start a Mono port to IA-64,would the same lburg code 
+   generator work for IA-64 also? or anything else need to be used for code 
+   generation(as the processor architecture is totally different from IA32)
+
+A: The lburg approach can be use for any processor architecture. But you might
+   think in another better approach.
+
+<a name="reuse"></a>
+** Reusing Existing Code
+
+Q: What projects will you reuse or build upon?
+
+A: We want to get Mono in the hands of programmers soon.  We are
+   interested in reusing existing open source software.
+
+Q: What about Intel's research JIT framework, ORP?
+
+A: At this time, we are investigating whether we can use elements of
+   ORP for Mono.   ORP is a research JIT engine that has a clearly
+   defined API that splits the JIT from the GC system and the actual
+   byte code implementation.
+
+   We are using some pieces of ORP (Their code generation interface)
+   and we use it as a source of inspiration for optimizations.  Paolo
+   and Dietmar consider ORP as being one of the best JIT engines out
+   there (and their research work and papers are very useful if you are
+   interested in JIT technology).
+
+Q: What about using GNU Lightning?
+
+A: We are not using GNU Lightning.  Our JIT is using an instruction
+   selector based on tree-pattern matching, and a code generation
+   interface that is very tied to the current architecture.
+
+Q: Will I be able to use Microsoft SQL Server 2000 or will I need to switch
+   to a specific Open Source Database. Will I need to recode?
+
+A: There should not be any need to recode.
+
+Q: What do I need to watch out for when programming in VB.NET so that I'm
+   sure to be able to run those apps on Linux?
+
+A: Not making any PInvoke or DLL calls should and not using anything in
+   the Microsoft.* namespaces should suffice. Also do not use any 
+   Methods/Classes marked as "This type/method supports the .NET Framework 
+   infrastructure and is not intended to be used directly from your code." 
+   even if you know what these classes/methods do.
+
+Q: Will built-in reporting be supported for crystal reports? This is a
+   heavily used part of our system.
+
+A: Probably not. Crystal Reports are propriety. Someone may try to emulate
+   the behaviour, but no-one has yet volunteered.
+
+Q: Who about writing to the registry? As I understand it, Linux does not have
+   a counterpart to the registry. Should I avoid relying on that feature?
+
+A: Try to avoid it. Although there would be a emulation for registry in
+   Mono too. GNOME does have a registry like mechanism for configuration. But
+   Even if gnome has a configuration system similar to the registry, the keys 
+   will not be equal, so you will probably end up having to do some runtime 
+   detection, and depending on this load an assembly that has your 
+   platform-specific hacks.
+
+Q: System.Data.SqlClient with FreeTDS, will you port parts of these to C# and 
+   use them?
+
+A: if their license is compatible with mono's, yes, we'd think about porting 
+   them. If not, we'll continue with the plan of using FreeTDS.
+
+<a name="gcc"></a>
+** Mono and GCC
+
+Q: Are you working on a GCC front-end to C#? A GCC backend that will
+   generate CIL images? What about making a front-end to GCC that
+   takes CIL images and generates native code?
+
+A: We are currently seeking volunteers for those projects.
+   Visit the <a href="contributing.html">contributing</a> section if
+   you are interested.
+
+Q: But would this work around the GPL in the GCC compiler and allow
+   people to work on non-free front-ends?
+
+A: People can already do this by targeting the JVM byte codes (there
+   are about 130 compilers for various languages that target the JVM).
+
+Q: Why are you writing a JIT engine instead of a front-end to GCC?
+
+A: We want the JIT engine and runtime engine because they will be able
+   to execute CIL executables generated on Windows, and so no recompilation 
+   will be necessary.
+
+<a name="performance"></a>
+** Performance
+
+Q: How fast will Mono be?
+
+A: We can not predict the future, but a conservative estimate is that
+   it would be at least `as fast as other JIT engines'.
+
+   We would like to ship various JIT engines with Mono, just like
+   Microsoft has done with their .NET development platform. We could
+   provide a faster, JIT for fast load times but lower performance,
+   and an and an optimizing JIT that would be slower at generating
+   code but produce more optimal output.
+
+   The CIL has some advantages over the Java byte code:  it is really
+   an intermediate representation and there are a number of
+   restrictions on how you can emit CIL code that simplify creating
+   better JIT engines.
+
+   For example, on the CIL, the stack is not really an abstraction
+   available for the code generator to use at will.  Rather, it is a
+   way of creating a postfix representation of the parsed tree.  At
+   any given call point or return point, the contents of the stack are
+   expected to contain the same object types independently of how the
+   instruction was reached.
+
+<a name="licensing"></a>
+** Licensing
+
+Q: Will I be able to write proprietary applications that run with
+   Mono?
+
+A: Yes.  The licensing scheme is planned to allow proprietary
+   developers to write applications with Mono.
+   
+Q: What license or licenses are you using for the Mono Project?
+
+A: The C# Compiler is released under the terms of the <a 
+   href="http://www.opensource.org/licenses/gpl-license.html">GNU GPL</a>.  The runtime
+   libraries are under the <a
+   href="http://www.opensource.org/licenses/lgpl-license.html">GNU
+   Library GPL</a>.  And the class libraries are released
+   under the terms of the <a
+   href="http://www.opensource.org/licenses/mit-license.html">MIT X11</a>
+   license.
+
+Q: I would like to contribute code to Mono under a particular
+   license. What licenses will you accept?
+
+A: We will have to evaluate the licenses for compatibility first,
+   but as a general rule, we will accept the code under the same
+   terms of the "container" module. 
+
+<a name="patents></a>
+** Patents
+
+Q: Could patents be used to completely disable Mono (either submarine
+   patents filed now, or changes made by Microsoft specifically to
+   create patent problems)?
+
+A: No.  First, its basic functional capabilities have pre-existed too
+   long to be held up by patents.  The basic components of Mono are
+   technologically equivalent to Sun's Java technology, which has been
+   around for years.  Mono will also implement multi-language and
+   multi-architecture support, but there are previous technologies
+   such as UCSD p-code and ANDF that also support multiple languages
+   using a common intermediate language.  The libraries are similar
+   to other language's libraries, so again, they're too similar to
+   be patentable in large measure.
+
+   However, if Microsoft does patent some technology, then our plan is
+   to either (1) work around it, (2) chop out patented pieces, (3) 
+   find prior art that would render the patent useless.
+ 
+   Not providing a patented capability would weaken the
+   interoperability, but it would still provide the free software /
+   open source software community with good development tools, which
+   is the primary reason for developing Mono.  
+
+<a name="etc"></a> 
+** Miscellaneous Questions
+
+Q: You say that the CLI allows multiple languages to execute on the
+   same environment.  Isn't this the purpose of CORBA?
+
+A: The key difference between CORBA (and COM) and the CLI is that the
+   CLI allows "data-level interoperability" because every
+   language/component uses the same data layout and memory management.
+
+   This means you can operate directly upon the datatypes that someone
+   else provides, without having to go via their interfaces.  It also
+   means you don't have to "marshall" (convert) parameters (data
+   layouts are the same, so you can just pass components directly) and
+   you don't have to worry about memory managment, because all
+   languages/components share the same garbage collector and address
+   space.  This means much less copying and no need for reference
+   counting.
+
+Q: Will you support COM?
+
+A: The runtime will support XPCOM on Unix systems and COM on Windows.
+   Most of the code for dynamic trampolines exists already.
+
+Q: Will Ximian offer certifications on Mono or related technologies?. 
+
+A: It's possible. But there is no plan about this. So the short answer is no.
+
+Q: Are there any Boehm's gc binaries?
+
+A: Yes. You can find them <a href="http://java.thn.htu.se/~toor/">here</a>
+
+Q: I have get into trouble when trying to build the site in my Linux box, what
+   can I do?.
+
+A: Try to change the line "./mono-rss.exe ../index deploy/index.rss" for
+   "mono ./mono-rss.exe ../index deploy/index.rss"
+
+Q: How can I report a bug?
+
+A: The best thing is to track down the bug and provide a simple test to
+   reproduce the bug. You can then add the bug to bugzilla:
+   http://bugzilla.ximian.com/enter_bug.cgi or simply send it to 
+   mono-list@ximian.com.
+
+Q: Does mcs support the same command line options as the MS C# 
+   compiler?
+
+A: The Mono C# compiler on CVS now supports the same command line
+   arguments as the Microsoft C# compiler does.

+
+	The Mono runtime can now be embedded into your application
+	(also known as "CLR hosting").  See the sample in
+	mono/samples/embed.  This allows your application to link with
+	the Mono runtime, then your C code can call into the C#/CIL
+	universe and back.
+
+	Peter Williams and Martin contributed some Makefiles to

+
+	Paolo today got mono to complete host itself on Linux.  This
+	means that we can now compile the `corlib' using the Mono C#
+	compiler and the Mono runtime.
+
+	Compiling the corlib was rather tricky, because the types that
+	the compiler uses during the compilation process will come
+	from the source code it is compiling.  
+
+	After a few months of work, we have finally fleshed out all
+	the remaining bugs.  Now the next step is to update the makefiles
+	to compile with the Mono tool-chain.
+
+	A recapitulation:
+	<ul>
+		* The Mono C# compiler was able to compile itself on December 28th, 2001.
+		  The resulting image contained errors though.
+
+		* The Mono C# compiler was able to self-compile in on
+		  January 3rd, 2002.  Becoming a self-hosting compiler on Windows.
+
+		* The Mono runtime matured enough by March 12, 2002 that it
+		  was able to bootstrap the Mono C# compiler on Linux using our interpreter.
+		  This means that our development tool was self sufficient.
+
+		* On March 26th, the JIT engine was fixed, so we could use this to
+		  run the compiler on Linux.
+
+		* Martin fixed the remaining bugs in the compiler that stopped it from
+	 	  compiling the `corlib'.  The resuling image still contained errors though.
+
+		* On July 8th, Radek got the PowerPC port to bootstrap
+		  the C# compiler.  This is important, because it exposed
+	  	  various tricky issues in a big-endian system.
+
+		* Today: we can bootstrap the compiler using libraries
+		  and the compiler compiled with itself on Linux.  The process is complete.
+	</ul>
+
+	In the meantime, Dietmar has quietly implemented the remaining
+	pieces of Marshalling in the Mono runtime.   This is very
+	important for the Gtk# guys to move on with their bindings.
+
+	To make things more interesting, he replaced most of the
+	architecture specific code generation for trampolines
+	(delegates, invocations, function and p/invoke trampolines) to
+	use CIL.  This CIL is then compiled on the flight by the JIT
+	Compiler engine.  By doing this, we have reduced the burden to
+	port the JITer to new architectures, and that our trampoline
+	code is cross platform.
+
+@item Looking for volunteers
+
+	We are looking for volunteers to help complete various pieces
+	of Mono and help move the project forward, we need
+	contributions to:
+
+	<ul>
+		* More tests to the existing class libraries.
+	
+		* Finish existing class libraries, check our <a
+		href="class-status.html">class status</a> pages to see
+		all the missing things.  There are open tasks all over
+		the place: XML, Database access, enterprise services,
+		configuration, ASP.NET, Drawing APIs, and more.
+
+		* Since we have now ASP.NET running, we would like to 
+		create an ASP.NET application to maintain our class
+		library documentation.
+
+		We have some special needs (read them <a
+	 	href="classlib-doc.html">here</a>).     There is a
+		prototype written using Windows.Forms, but we believe
+		it will be faster to have this done using ASP.NET (and
+		it is also a nice way of stress testing it).
+
+		* Support for the VB runtime: we need contributions
+		to make our VB runtime mature enough to host
+		applications compiled with the VB.NET to run with
+		Mono.
+
+		* We need people to help write the documentation: you
+		can start editing our XML files by hand, and once we
+		have the ASP.NET tool, upgrade to that. 
+	</ul>

+
+	Ajay was the first to notice <a
+	href="http://lists.ximian.com/archives/public/mono-list/2002-July/000641.html">
+	Mono's first birthday</a>.
+
+	In a year, we have achieved plenty:
+	<ul>
+		* 94 contributors with CVS access (84 non-Ximian developers).
+		* A complete CLI implementation:
+		<ul>
+			<li> A fast and performing x86 JIT engine (inlining, constant propagation).
+			<li> An interpreter for other systems (PPC, Sparc, StrongArm).
+		</ul>
+		* A self-hosting C# compiler, which can compile its class libraries.
+		* 37,140 file changes in CVS.
+		* 92,000 lines of C code.
+		* 437,000 lines of C# code (compiler, classes, tests)
+		* A working core for ASP.NET and ADO.NET.
+		* Major subsystems are functional: RegularExpressions,
+		  System.XML, XML.Schema, System.Data, System.Web.
+		* The Gtk# project, which is maturing rapidly.
+	</ul>
+
+	Thanks to everyone who has made Mono possible with their
+	feedback, regression tests, their comments, their help on the mailing
+	list, code contributions, complete classes, bug reporting, the
+	countless hours of bug hunting.  This project would not have
+	been possible without every contribution.  
+
+	It has been a great year for everyone involved in the
+	project.  I think we have built a new and exciting community.
+
+	Now we have a solid foundation to build on, so this next year
+	looks even more exciting: not only because we will see more
+	Mono applications, but we will begin using Mono as an
+	`library' to be linked with applications that want to get
+	scripting-like features; Gtk# is our ticket to create nice
+	GNOME applications; And we will be developing CORBA bindings
+	to integrate with other object systems.
+
+	Also, for those interested in optimizations and tuning, this
+	year we will get to play with more advanced optimizations and
+	all kinds of interesting research ideas for improving Mono
+	code generation.
+
+	A special thanks to the Mono developers at Ximian for managing
+	to survive their manager and a special thanks to our
+	regression test marshal Nick Drochak, who has been hunting
+	down, and fixing code in our class libraries and keeping us on
+	track for so long.
+

+
+	Radek today fixed the last bugs to get Mono to self host on
+	Linux/PowerPC.
+
+	Alp Toker has released version 0.5 of <a
+	href="http://www.atoker.com/phonic/">Phonic</a>, a media
+	player for .NET. Phonic makes extensive use of Mono-developed
+	technologies such as Gtk# and csvorbis (Ogg player ported by
+	Mark). Hopefully we will be seeing many more exciting
+	applications like these in the near future.
+
+	Dietmar has been moving a lot of the architecture specific
+	code in the JIT engine to our internal representation.  This
+	means that porting the JIT is simpler now, as there is less
+	architecture-specific code to maintain.  The inliner, constant
+	folder and constant propagation are also done at the
+	architecture independent layer.
+
+	Gonzalo is now running the sample ASP.NET applications on
+	Linux with the Mono runtime.  It still needs polishing though,
+	and help with the various ASP.NET controls would be
+	appreciated.  The ASP.NET community seems more poor than the
+	PHP community, we need to have a few open source controls to
+	do things dynamic rendering (libart+gdk-pixbuf again can do
+	most of the work), charts and components like the kind of
+	thing you see in the PHP universe: to bring nice GPL code to
+	the masses of Windows developers, lure them into the world of
+	Linux.
+
+	Dick has also got us the new Process implementation that
+	implements the Win32 semantics.  Now only redirection is
+	missing.

+
+	Martin Baulig fixed the remaining bugs that prevented MCS to
+	compile our corlib.  The compilation was tricky because of the way
+	MCS bootstraps the compile (internally mcs uses the types that are
+	being defined at that point to perform compares).
+
+	Martin and Paolo have been working hard on fixing the
+	remaining issues.  Currently 102 test pass and 15 fail with
+	our resulting corlib.
+
+	Jesus' SoapFormatter classes are now in CVS.
+
+	I have been redoing the type lookup system for MCS.  The
+	interesting bit is that I did most of this work on an airplane

+	now a good development tool.

+
+	Some updates from the hacking lines:
+
+	<b>The web:</b> Patrik Torstensson last week contributed the
+	http runtime support and started work on thread pools.  This
+	is part of the ASP.NET support.
+
+	<b>Docs:</b> John Barnette, John Sohn and Adam Treat have been
+	hacking on MonoDoc.
+
+	<b>ADO.NET:</b> Daniel Morgan and Rodrigo Moya have been
+	working on the <a href="ado-net">ADO.NET</a> support, and got
+	the first signs of life this week (we can connect, insert
+	rows; do transactions: commit/rollback; SQL errors and
+	exceptions work).  Check <a
+	href="mailing-lists.html">mono-patches</a> for all the
+	goodies.
+
+	<b>Optimizations:</b> A number of optimizations in the runtime
+	made the compiler twice as fast this week:
+
+	Early this week Patrik started the string
+	rewrite in the runtime.  Today Dietmar finished the
+	constructors and deployed the new layout. 
+
+	Paolo got the JIT engine to generate profiles, which were in
+	turn used to find hot spots in Reflection, which he improved.
+
+	Daniel Lewis (of Regex fame) noticed the performance issues
+	with our current array layout, and contributed a new array
+	representation.
+
+	At the same time Dietmar started the the JIT inline code and
+	implemented constant propagation.  These two optimizations
+	together are very powerful.
+
+	<b>Bug fixing:</b> And of course everyone has been helping out
+	with the bug fixing (Duncan, Gonzalo, Jonathan, Miguel, Nick,
+	Ravi, Sergey)
+
+
+@item Apr 18, 2002
+
+	Dietmar's inlining for the JIT engine just landed into

+		* The C# compiler is being worked on and can compile

+* Java
+
+	It would be interesting to support the Java language as part
+	of the Mono project.  
+
+	You have to think of Java as various pieces: Java the
+	language and Java the virtual machine.  
+
+	It is possible to compile Java to .NET, as shown by the
+	Microsoft J# compiler.   We could then allow the migration of
+	Java applications to the Mono runtime. 
+
+** Native compiler
+
+	Although a native compiler can be built, and probably should be
+	built using an existing compiler, a short term solution is to 
+	build a translator from Java class files to the ECMA CIL images.
+
+	This has the advantage that we can use an existing and tested
+	Java compiler to generate the code, and then we can use an automated
+	code compiler that compiles Java VM bytecodes to CIL bytecodes.
+
+** The translator.
+
+	It would be interesting to write a semantic translator that
+	converts java byte codes into CIL opcodes.  This is possible
+	because the Java byte codes are a subset of the CIL ones.
+
+	A semantic tree needs to be constructed (very much in the
+	spirit of what is done in mono_analize_stack in
+	<tt>mono/mono/jit/jit.c</tt>.  Once such a semantic tree is
+	constructed, we could generate the equivalent Java code.
+
+	This has a number of interesting side effects: people can
+	continue to use their existing Java compilers to compile their
+	code, and a simple tool that converts their .class files into
+	a .NET assembly can be used.
+
+** Libraries
+
+	We could translate the GNU Classpath libraries with the above
+	tools to provide the Java runtime required to host into the
+	Mono runtime.  Some special treatment would be required for
+	core data types like integers, arrays and strings, and of
+	course reuse where possible existing classes from .NET to make
+	them compatible.
+
+** JILC - Java to IL Compiler
+
+	This is an attempt to make the java bytecode available for the
+	.NET environment.
+
+	The project attempts to generate the IL code / bytecode from the
+	compiled java class files. It has reached the stage of code-generation.
+	The issues that needs to be addressed is the mapping of java objects
+	to the IL objects, eg: java.lang.String to System.String.
+
+	Gaurav Vaish and Abhaya Agarwal are currently leading this project.
+	The project is currently hosted at <a href="http://sourceforge.net/projects/jilc">SourceForge.Net</a>.
+	The official home page of the project is 
+	<a href="http://jilc.sourceforge.net">http://jilc.sourceforge.net</a>.

+* How to debug your C# application with the JIT engine 
+
+	To debug a C# application you need to run the JIT in your debugger.
+
+	Before you can do anything useful in a debugger, you need a symbol
+	file which tells your debugger about functions, types, line numbers
+	and such. Unfortunately, this symbol file needs to be recreated each
+	time the JIT compiles a new method since it doesn't know anything
+	about this method (especially not its memory address) before actually
+	compiling it.
+
+	You have two ways of creating a symbol file:
+
+** Letting the JIT dynamically create the symbol file
+
+	This'll give you a symbol file which is suitable for debugging IL byte
+	code - you won't see your C# source code.
+
+	However, this method has the advantage that it works with every assembly,
+	no matter whether it has been compiled with Mono's C# compiler (MCS) or
+	with any other compiler. It's currently the only way to debug
+	<tt>corlib.dll</tt> or any other library which cannot be compiled with
+	our compiler yet.
+
+	All that you need is a dump of the IL bytecode for each assembly (including
+	all assemblies this assembly is referencing). This is done by using the
+	<tt>monodis</tt> utility:
+
+	<pre>
+	monodis /home/export/martin/MONO-LINUX/lib/corlib.dll > corlib.il<br>
+	monodis /home/export/martin/MONO-LINUX/lib/System.dll > System.il<br>
+	monodis /home/export/martin/MONO-LINUX/bin/mcs.exe > mcs.il
+	</pre>
+
+	Make sure that all the .il files have the same name as their corresponding
+	assembly and that they're all created in the current directory.
+
+	The JIT supports two different debugging file formats:
+
+	<ul>
+	* STABS: This is a very simple debugging format, but it may be the only one
+	which is supported on your system. It is limited to source files of no more
+	than 65.535 lines and it's type support is also very limited. You should only
+	use this if your debugger doesn't support DWARF 2.
+
+	To generate STABS output, use the <tt>--stabs</tt> command line argument.
+
+
+	* DWARF 2: The DWARF 2 debugging format is a very powerful debugging format
+	which can handle source files of arbitrary size and has a highly sophisticated
+	type support. It's the recommended format unless you need to use STABS because
+	your debugger doesn't support DWARF 2.
+
+	To generate DWARF 2 output, use the <tt>--dwarf</tt> command line argument.
+	</ul>
+
+
+	You need to regenerate the symbol file each time the JIT compiled a new
+	method and each time you restart the JIT. You cannot reuse your symbol file
+	if you start the JIT a second file, not even if you're running the same
+	application with the same input data a second time.
+
+	Regenerating the symbol file is done by calling the JIT's
+	<tt>mono_debug_make_symbols ()</tt> function from within your debugger and
+	then reloading the symbol files. This function creates a <tt>filename-dwarf.s</tt>
+	(or <tt>filename-stabs.s</tt>) assembler input file in the current directory and
+	an object file in <tt>/tmp/filename.o</tt> - you need to tell your debugger to
+	add this object file as symbol file.
+
+	If you're using the GNU debugger, this is done like this:
+
+	<pre>
+	call mono_debug_make_symbols ()
+	add-symbol-file /tmp/corlib.o
+	add-symbol-file /tmp/mcs.o
+	add-symbol-file /tmp/Mono.CSharp.Debugger.o
+	</pre>
+
+	You can also write a GDB macro like this:
+
+	<pre>
+	define reload
+	  call mono_debug_make_symbols ()
+	  add-symbol-file /tmp/corlib.o
+	  add-symbol-file /tmp/mcs.o
+	  add-symbol-file /tmp/Mono.CSharp.Debugger.o
+	end
+	</pre>
+
+	Then you can just say <tt>reload</tt> to have GDB recreate the symbol file.
+
+	There's also an <a href="jit-debug-sample.html">example debugging session</a> using
+	the GNU debugger.
+
+** Using a symbol file which have been created by the Mono C# compiler
+
+	If you compiled your application with Mono's C# compiler (MCS), you can tell it to
+	create a symbol file which is then processed and rewritten by the JIT engine.
+
+	To do this, you must give MCS the <tt>-g</tt> option:
+
+	<pre>
+	$ mcs -g Foo.cs
+	</pre>
+
+	This creates a <tt>Foo-debug.s</tt> assembler input file.
+
+	To use this in the JIT, you must first copy it to the target machine (the machine
+	where you want to run the JIT to debug your application) and run it through the
+	assembler to produce an object file <tt>Foo-debug.o</tt>. This object file must be
+	in the current directory.
+
+	Then start the JIT in your debugger and give it the <tt>--dwarf-plus</tt> command
+	line argument.
+
+	Each time you call <tt>mono_debug_make_symbols ()</tt> from withing your debugger,
+	the JIT will read this <tt>Foo-debug.o</tt>, fix some machine dependent things like
+	memory addresses etc. in it and write it back to disk.
+
+	If you're using the GNU debugger, you'll want to use a macro like this:
+
+	<pre>
+	define relocate
+	  call mono_debug_make_symbols ()
+	  add-symbol-file /tmp/corlib.o
+	  add-symbol-file mcs-debug.o
+	  add-symbol-file Mono.CSharp.Debugger-debug.o
+	end
+	</pre>
+
+	If there is no <tt>assembly-debug.o</tt> file, but an <tt>assembly.il</tt> one, the
+	JIT will fall back to normal DWARF 2 (in the example above, <tt>corlib.dll</tt> was
+	compiled with Microsoft's compiler and the JIT is thus using DWARF to debug it).
+
+	This debugging method only works if you compiled your assembly with MCS, but it'll
+	allow you to actually debug your C# source code :-)
+
+	Here's an <a href="jit-debug-sample2.html">example debugging session</a> using
+	the GNU debugger.
+
+** Breakpoints and single stepping
+
+	The JIT has a <tt>--debug</tt> command line argument to insert a breakpoint at the
+	beginning of this method. It takes a <tt>Namespace.Class:Method</tt> argument which
+	is the method. This argument can be given multiple times.
+
+	However, once your application is stopped in GDB you may want to insert a breakpoint
+	the next time the JIT compiles a method. There's a global variable
+	<tt>mono_debug_insert_breakpoint</tt> which you can modify in your debugger.
+
+	If this variable is set to a non-zero value, the JIT's <tt>arch_compile_method</tt>
+	will insert a breakpoint the next time it is called, ie. at the top of the next
+	method it compiles. If this value has a positive value, it acts as a counter and is
+	decremented after inserting the breakpoint - setting it to a negative value will let
+	the JIT insert the breakpoint each time it compiles a new method.
+
+	There's also global variable <tt>mono_debug_last_breakpoint_address</tt> which always
+	contains the address of the last inserted breakpoint. You may manually override this
+	address with a <tt>nop</tt> instruction to delete the breakpoint.
+
+	For instance, I have a GDB macro called <tt>enter</tt> which I use to enter a method
+	rather than stepping over it:
+
+	<pre>
+	define enter
+	set mono_debug_insert_breakpoint = 1
+	continue
+	set *mono_debug_last_breakpoint_address = 0x90
+	relocate
+	frame
+	</pre>
+
+	Btw. speaking of single stepping - you should use your debuggers <tt>next</tt> command,
+	not its <tt>step</tt> command for single stepping unless you compiled the JIT without
+	debugging support. The reason for this is that the JIT creates machine code which contains
+	calls to JIT methods such as <tt>mono_object_new_wrapper</tt> at places where you don't
+	expect them - so unless the JIT is compiled at least without line numbers, your debugger
+	will enter such methods if you use <tt>step</tt> rather than <tt>next</tt>.

+	href="http://www.mozilla.org/rhino/">Rhino</a>.
+
+	You could port this code from Java to C#.
+
+	Note that since JavaScript allows for evaluation at runtime,
+	the compiler has to be built as a class that can be invoked at
+	runtime.
+
+<a name="c">
+* C
+
+	Ideally GCC could be modified to generate CIL, but it is a 
+	big task.  That would give us various compilers in one pass.
+
+	Rumor is that the next version of the LCC compiler will
+	include an IL backend.  We do not know how extensive the support
+	for integration with .NET will be, but it would be an interesting
+	excercise to add an extension to C to call into .NET code.
+
+	LCC is not an open source compiler, but it is free as long as you
+	do not profit from selling it. 
+
+<a name="Java">
+* Java
+
+	We have a <a href="java.html">separate page</a> for Java.

+<title>Introduction</title>
+
+<para>
+Mono is an open source implementation of the Common Language Infrastructure
+(CLI) specified in ECMA standard 335. It comes with a C# compiler and
+provides an extensible platform to develop and run applications that
+are interoperable with Microsoft .NET.
+</para>
+
+<para>
+Mono is not finished--it is a project still under development. As a
+result, installation and configuration may not be as smooth as you
+will be used to from other Linux applications. Nevertheless, mono is
+in a state that will allow you to get it up and running and gain
+experience with it--which is, I would suggest, a very smart thing to do.
+</para>
+
+<para>
+This document is limited in the following sense: it describes how to
+download a 'stable' version of mono as a 'tarball' and get it to run on
+your computer. I'm also assuming you run mono on Linux rather than
+on Windows. All the examples have been tested on a 'vanilla' Red Hat 7.3 
+installation.
+</para>
+
+<para>
+There are two items this document will <emphasis>not 
+</emphasis> cover: the first is how to self host the mcs compiler 
+under linux and the second is the graphical user environment 
+which is implemented as GTK#. These two interesting topics 
+are the subject of two more howto's that I'm planning.
+</para>
+
+<para>
+This document is also less useful for two types of people.
+</para> 
+<itemizedlist> 
+<listitem> 
+<para> 
+If you are a very inexperienced linux user and want to know what mono is
+all about, there is an easier way to install mono. Go to mono.baselabs.org
+and download the rpm's ready for installation on your system. This site also
+runs a tutorial that is worth reading.
+</para> 
+</listitem> 
+<listitem> 
+<para> 
+If you are a very experienced user wanting to contribute to the mono code,
+you should probably regularly do a CVS download. At the moment, the mono
+code grows very fast, and the 'stable' releases still appear too slowly.
+</para>
+</listitem>
+
+</itemizedlist>
+
+<para>
+This document is aimed at the mono beginner, and aims to present a complete
+view of a minimal installation, which will allow you to experiment with
+mono to some degree. It also describes some of those experiments. We
+expect that after reading this document you'll go on to do either of
+two things:
+</para>
+<orderedlist>
+<listitem>
+<para>
+Continue to contribute to the mono project in some shape or form. The
+website has some ideas and suggestions under the heading 'Contributing'.
+</para>

+<listitem>
+<para>
+Continue to write applications that run in mono.

+This document is expected to grow into a full 'running mono howto' over time.
+As of yet, it does not really discuss some of the excellent efforts of others
+to package mono into an rpm or deb and prepare it for easy installation.
+It is our aim to include this in future versions of this document.

+To compile mono on your system, you will also have to satisfy 
+some dependencies on other software. A list of these are given 
+on the mono download page. Read through this list to see if 
+you've got all components.

+There are several ways to get Mono running on your computer. This
+document will discuss only one of those: downloading the source tarball
+and utilising the make utilities to get mono up and running.  There is
+only one mono package to worry about if you are just after a 'base' install
+of mono: the mono runtime. This package, found under the name "mono-x.xx"
+has got a compiled version of the compiler built in.
+</para>
+
+<para>
+You'll be able to complete everything in this document if you just install
+the runtime, but taking a look at the compiler package is well worth the
+effort. The compiler is written in C# and is 'self hosting' which means it
+is able to compile itself. 
+</para>
+
+<para>
+As of this moment, it is my understanding that there are still some issues
+with the 'self hosting' bit of the compiler on linux, although this is 
+expected to work in later versions of mono. If you are just interested in
+finding out how mono will work under linux, I would not worry about the
+self-hosting bit for now. The self-hosting of the compiler will be the
+topic of a future howto.
+</para>
+
+<para> 
+See <ulink url="http://www.go-mono.com/download">the mono download
+site</ulink> for the source of the tarballs.  
+</para>
+
+<para>
+This page also lists the current versions of the software 
+mono depends on. Make sure that your system has all the 
+required versions, otherwise mono won't compile.
+</para>
+
+<para>
+At a minimum for mono 0.12, you'll need to:

+
+<para> 
+Installing the tarballs is done via GNU autoconf and
+automake. The general upshot of running autoconf and automake is that you
+can type <command>./configure</command> and then <command> make</command>
+to do the build.  
+Typing <command>make install</command> completes the installation of mono
+on your system.
+</para>
+
+<para>
+To build the mono runtime package, unzip the tarball to some useful
+location.  I tend to use <command>/usr/src</command> as the location,
+but you could really do it anywhere. For the install process, it is
+also a good idea to be 'root'.  The installation process will shuttle
+some executables into <command>/usr/local/bin</command> (more about
+that later).
+</para>
+
+<para>
+Unzipping the tarballs will have created two directories in <command>
+/usr/src/</command>, one called something like mono-x.xx and the other 
+mcs-x.xx. The one called 'mono' is the runtime environment, and this contains
+all that is initially needed to run mono and investigate its inner workings.
+</para>
+
+<para>
+To start building the mono runtime, first type <command>./configure</command>.

+You are now ready to start the mono "build" process. To kick

+about these.
+</para>
+<para>
+To finally install mono, you can type <command>make install</command> 
+to get a working version of mono. This command will copy the

+<sect2 id="garbage_collection">
+<title> Garbage Collection</title>
+<para>
+To make the mint interpreter work with garbage collection, you first need to
+install a garbage collection package on your system. Mono works with
+Boehm Garbage collection, which is found at 
+<ulink url="http://www.hpl.hp.com/personal/Hans_Boehm/gc/">
+http://www.hpl.hp.com/personal/Hans_Boehm/gc/
+</ulink>.
+</para>
+
+<para>
+To get garbage collection to work, I downloaded the source tarball 
+into <command>/usr/src/</command> and typed <command>./configure</command>
+followed by <command>make</command> and <command>make install</command>.
+</para>
+
+<para>
+There is one glitch to work around. The header file for the garbage collection
+<command>gc.h</command> is found in the <command>/usr/src/gc6.0/include
+</command> directory (at least on my system). The mono build process will break
+on this location: it is looking for the header file in some other place called
+<command>/usr/include/gc/</command> and won't be able to find the correct
+header file.
+</para>
+
+<para>
+The solution is to build a symbolic link between these two locations as 
+follows
+</para>
+
+<programlisting>
+[root@taurus include]# ln -s /usr/src/gc6.0/include/ /usr/include/gc
+</programlisting>
+

+To work with mono, you first have to create a C# program. Open up 
+your favourite editor, and type in the following code:
+</para>
+<programlisting>
+using System;
+
+class Hello
+{
+public static void Main(String[] args)
+	{
+	Console.WriteLine("mono:: is alive and well...");
+

+		Console.WriteLine("Argument {0} = {1}", i, args[i]);
+	}
+}
+</programlisting>
+
+<para>
+Save the file as hello.cs. To compile this into a working program, 
+type mcs hello.cs. If you get the following:
+</para>
+<programlisting>
+[hinne@taurus hello]$ mcs hello.cs
+RESULT: 0
+[hinne@taurus hello]$
+</programlisting>
+<para>
+you know the compile worked fine. If you see some strange error
+messages including the word 'parser' somewhere, you made a mistake in
+your program. Fix this up first.
+</para>
+
+<para>
+You are now ready to execute your first mono program.  To execute 
+the code, type
+</para>
+
+<programlisting>
+[hinne@taurus hello]$ mono hello.exe arg1 arg2 arg 3
+</programlisting>
+<para>
+(where we have given some arguments just for fun) and you'll 
+see the following:
+</para>
+
+<programlisting>
+mono:: is alive and well...
+Argument 0 = arg1
+Argument 1 = arg2
+Argument 2 = arg
+Argument 3 = 3
+RESULT: 0
+</programlisting>
+<para>
+As you can see, mono printed the line "mono:: is alive and well" 
+and printed the list of arguments. This completes the creation 
+and execution of your first mono program.
+</para>
+</sect2>
+
+<sect2 id="interpreter">
+<title>Interpreter</title>
+<para>
+But mono will allow you to do more. First of all, mono is the 
+compiled mono execution environment which uses the Just in 
+Time (JIT) compiler. Mono also comes with an interpreted 
+environment, which can be accessed using the command 'mint' 
+as follows
+</para>
+<programlisting>
+[hinne@taurus hello]$ mint hello.exe arg1 arg 2
+mono:: is alive and well...
+Argument 0 = arg1
+Argument 1 = arg
+Argument 2 = 2
+[hinne@taurus hello]$
+</programlisting>
+<para>
+As you can see, it makes no difference to mono output which 
+environment you use, but what happens under the hood is very 
+different. If you use 'mono' as the command line tool, you 
+call the 'production' execution environment which will read 
+your portable executable (PE) file, and call the just in 
+time (JIT) compiler to compile the PE code down to machine 
+level code (in my case, an x86 architecture) after which 
+it is executed.
+</para>
+<para>
+If you use mint, the JIT is not used, and the PE code is 
+interpreted into x86 instructions for execution. In fact, 
+for our simple 'hello' mint is slightly faster. The point 
+is that the JIT compiler will take some time to compile the 
+code of our program and store it in some location in memory, 
+but the subsequent execution of the code is faster with mono.
+</para>
+<para>
+
+You can see what happens below (the thing to look for is the 
+'user' time: 0.1 seconds with mono and 0.06 seconds with mint):
+
+</para>
+<programlisting>
+[hinne@taurus hello]$ time mono hello.exe arg1 arg 2

+Argument 1 = arg

+After this simple run of mono, it is time to play with some options.

+Mono supports a debugging option when you specify the "-d" flag while running
+the runtime. Utilising this flag will get you a significant amount of output,
+and it may be an idea to specify an output file as well. The interesting aspect

+
+<para>The purpose of this License is to make a manual, textbook,
+    or other written document "free" in the sense of freedom: to assure
+    everyone the effective freedom to copy and redistribute it, with
+    or without modifying it, either commercially or noncommercially.
+    Secondarily, this License preserves for the author and publisher
+    a way to get credit for their work, while not being considered
+    responsible for modifications made by others.</para>
+
+<para>This License is a kind of "copyleft", which means that
+    derivative works of the document must themselves be free in the
+    same sense.  It complements the GNU General Public License, which
+    is a copyleft license designed for free software.</para>
+
+<para>We have designed this License in order to use it for manuals
+    for free software, because free software needs free documentation:
+    a free program should come with manuals providing the same freedoms
+    that the software does.  But this License is not limited to software
+    manuals; it can be used for any textual work, regardless of subject
+    matter or whether it is published as a printed book.  We recommend
+    this License principally for works whose purpose is instruction
+    or reference.</para>
+</sect3>
+
+<sect3 id="gfdl-1"> <title>APPLICABILITY AND DEFINITIONS</title>
+
+<para>This License applies to any manual or other work that
+    contains a notice placed by the copyright holder saying it can be
+    distributed under the terms of this License.  The "Document", below,
+    refers to any such manual or work.	Any member of the public is a
+    licensee, and is addressed as "you".</para>
+
+<para>A "Modified Version" of the Document means any work
+    containing the Document or a portion of it, either copied verbatim,
+    or with modifications and/or translated into another language.</para>
+
+<para>A "Secondary Section" is a named appendix or a front-matter
+    section of the Document that deals exclusively with the relationship
+    of the publishers or authors of the Document to the Document's overall
+    subject (or to related matters) and contains nothing that could fall
+    directly within that overall subject.  (For example, if the Document
+    is in part a textbook of mathematics, a Secondary Section may not
+    explain any mathematics.)  The relationship could be a matter of
+    historical connection with the subject or with related matters, or
+    of legal, commercial, philosophical, ethical or political position
+    regarding them.</para>
+
+<para>The "Invariant Sections" are certain Secondary Sections
+    whose titles are designated, as being those of Invariant Sections,
+    in the notice that says that the Document is released under this
+    License.</para>
+
+<para>The "Cover Texts" are certain short passages of text that
+    are listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+    that says that the Document is released under this License.</para>
+
+<para>A "Transparent" copy of the Document means a
+    machine-readable copy, represented in a format whose specification
+    is available to the general public, whose contents can be viewed and
+    edited directly and straightforwardly with generic text editors
+    or (for images composed of pixels) generic paint programs or
+    (for drawings) some widely available drawing editor, and that is
+    suitable for input to text formatters or for automatic translation
+    to a variety of formats suitable for input to text formatters.
+    A copy made in an otherwise Transparent file format whose markup
+    has been designed to thwart or discourage subsequent modification
+    by readers is not Transparent.  A copy that is not "Transparent"
+    is called "Opaque".</para>
+
+<para>Examples of suitable formats for Transparent copies include
+    plain ASCII without markup, Texinfo input format, LaTeX input format,
+    SGML or XML using a publicly available DTD, and standard-conforming
+    simple HTML designed for human modification.  Opaque formats include
+    PostScript, PDF, proprietary formats that can be read and edited
+    only by proprietary word processors, SGML or XML for which the
+    DTD and/or processing tools are not generally available, and the
+    machine-generated HTML produced by some word processors for output
+    purposes only.</para>
+
+<para>The "Title Page" means, for a printed book, the title page
+    itself, plus such following pages as are needed to hold, legibly,
+    the material this License requires to appear in the title page.
+    For works in formats which do not have any title page as such,
+    "Title Page" means the text near the most prominent appearance of the
+    work's title, preceding the beginning of the body of the text.</para>

+
+<sect3 id="gfdl-2"> <title>VERBATIM COPYING</title>
+
+<para>You may copy and distribute the Document in any medium,
+    either commercially or noncommercially, provided that this License,
+    the copyright notices, and the license notice saying this License
+    applies to the Document are reproduced in all copies, and that
+    you add no other conditions whatsoever to those of this License.
+    You may not use technical measures to obstruct or control the
+    reading or further copying of the copies you make or distribute.
+    However, you may accept compensation in exchange for copies.  If you
+    distribute a large enough number of copies you must also follow the
+    conditions in section 3.</para>
+
+<para>You may also lend copies, under the same conditions stated
+    above, and you may publicly display copies.</para>
+</sect3>
+
+<sect3 id="gfdl-3"> <title>COPYING IN QUANTITY</title>
+
+<para>If you publish printed copies of the Document numbering more
+    than 100, and the Document's license notice requires Cover Texts, you
+    must enclose the copies in covers that carry, clearly and legibly,
+    all these Cover Texts: Front-Cover Texts on the front cover, and
+    Back-Cover Texts on the back cover.  Both covers must also clearly
+    and legibly identify you as the publisher of these copies.	The front
+    cover must present the full title with all words of the title equally
+    prominent and visible.  You may add other material on the covers
+    in addition.  Copying with changes limited to the covers, as long as
+    they preserve the title of the Document and satisfy these conditions,
+    can be treated as verbatim copying in other respects.</para>
+
+<para>If the required texts for either cover are too voluminous to
+    fit legibly, you should put the first ones listed (as many as fit
+    reasonably) on the actual cover, and continue the rest onto adjacent
+    pages.</para>
+
+<para>If you publish or distribute Opaque copies of the Document
+    numbering more than 100, you must either include a machine-readable
+    Transparent copy along with each Opaque copy, or state in or with each
+    Opaque copy a publicly-accessible computer-network location containing
+    a complete Transparent copy of the Document, free of added material,
+    which the general network-using public has access to download
+    anonymously at no charge using public-standard network protocols.
+    If you use the latter option, you must take reasonably prudent steps,
+    when you begin distribution of Opaque copies in quantity, to ensure
+    that this Transparent copy will remain thus accessible at the stated
+    location until at least one year after the last time you distribute
+    an Opaque copy (directly or through your agents or retailers) of
+    that edition to the public.</para>
+
+<para>It is requested, but not required, that you contact the
+    authors of the Document well before redistributing any large number
+    of copies, to give them a chance to provide you with an updated
+    version of the Document.</para>

+
+<sect3 id="gfdl-4"> <title>MODIFICATIONS</title>
+
+<para>You may copy and distribute a Modified Version of the
+    Document under the conditions of sections 2 and 3 above, provided
+    that you release the Modified Version under precisely this License,
+    with the Modified Version filling the role of the Document, thus
+    licensing distribution and modification of the Modified Version
+    to whoever possesses a copy of it.	In addition, you must do these

+    of Front-Cover Text and one of Back-Cover Text may be added by (or

+    modified versions, provided that you include in the combination all of
+    the Invariant Sections of all of the original documents, unmodified,

+    section unique by adding at the end of it, in parentheses, the
+    name of the original author or publisher of that section if known,
+    or else a unique number.  Make the same adjustment to the section
+    titles in the list of Invariant Sections in the license notice of

+<para>A compilation of the Document or its derivatives with other
+    separate and independent documents or works, in or on a volume
+    of a storage or distribution medium, does not as a whole count
+    as a Modified Version of the Document, provided no compilation
+    copyright is claimed for the compilation.  Such a compilation is
+    called an "aggregate", and this License does not apply to the other
+    self-contained works thus compiled with the Document, on account
+    of their being thus compiled, if they are not themselves derivative
+    works of the Document.</para>
+
+<para>If the Cover Text requirement of section 3 is applicable to
+    these copies of the Document, then if the Document is less than
+    one quarter of the entire aggregate, the Document's Cover Texts

+
+<sect3 id="gfdl-8"> <title>TRANSLATION</title>
+
+<para>Translation is considered a kind of modification, so you may
+    distribute translations of the Document under the terms of section 4.
+    Replacing Invariant Sections with translations requires special
+    permission from their copyright holders, but you may include
+    translations of some or all Invariant Sections in addition to the
+    original versions of these Invariant Sections.  You may include
+    a translation of this License provided that you also include the
+    original English version of this License.  In case of a disagreement
+    between the translation and the original English version of this
+    License, the original English version will prevail.</para>
+</sect3>
+
+<sect3 id="gfdl-9"> <title>TERMINATION</title> <para>You may not copy,
+modify, sublicense, or distribute the
+    Document except as expressly provided for under this License.
+    Any other attempt to copy, modify, sublicense or distribute the
+    Document is void, and will automatically terminate your rights under
+    this License.  However, parties who have received copies, or rights,
+    from you under this License will not have their licenses terminated
+    so long as such parties remain in full compliance.</para>

+<sect3 id="gfdl-10"> <title>FUTURE REVISIONS OF THIS LICENSE</title>
+
+<para>The Free Software Foundation may publish new, revised
+    versions of the GNU Free Documentation License from
+    time to time.  Such new versions will be similar
+    in spirit to the present version, but may differ in
+    detail to address new problems or concerns.  See <ulink
+    url="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</ulink>.</para>
+
+<para>Each version of the License is given a distinguishing
+    version number.  If the Document specifies that a particular
+    numbered version of this License "or any later version" applies
+    to it, you have the option of following the terms and conditions
+    either of that specified version or of any later version that has
+    been published (not as a draft) by the Free Software Foundation.
+    If the Document does not specify a version number of this License,
+    you may choose any version ever published (not as a draft) by the
+    Free Software Foundation.</para>
+</sect3>
+
+<sect3 id="gfdl-11"> <title>How to use this License for your
+documents</title>
+
+<para>To use this License in a document you have written, include

+
+<para>If you have no Invariant Sections, write "with no Invariant

+			<Mono newbie coders start file>
+	<h1> A little help for mono newbie coders </h1>
+
+
+	For those who are new to Mono and are impatient to contribute
+	with code (uhh... you are brave!!) here is the document you 
+	should read.
+
+	
+	You will see all Mono hackers say the same (great minds have
+	similar way of thinking): First, DO WRITE TESTS!!!. In order
+	to do that:
+	
+	<ul>
+		* Start with the NUnit Tests Guidelines.  In the cvs
+	    	  they are located at: mcs/class/doc/NUnitGuideli...
+
+		* But wait, this is a document for impatient
+	    	  people. So EVERYTHING should be here. Well, it is. 
+	</ul>
+
+
+	<h2> The NUnit Tests Guidelines document </h2>
+
+	Mono NUnit Test Guidelines and Best Practices
+
+	Authors: Nick Drochak  <ndrochak@gol.com>
+	Martin Baulig  <martin@gnome.org>
+	Last Update: 2002-03-02
+	Rev: 0.3
+
+ <b> Purpose </b>
+
+	This document captures all the good ideas people have had 
+	about writing NUnit tests for the mono project. This document 
+	will be useful for anyone who writes or maintains unit tests.
+
+ <b> Other resources </b>
+
+	- mcs/class/README has an explanation of the build process and
+	  how it relates to the tests.
+	- http://nunit.sourceforge.net is the place to find out about 
+	  NUnit
+
+ <b> Getting Started </b>
+
+	If you are new to writing NUnit tests, there is a template 
+	you may use to help get started. The file is:
+
+	mcs/class/doc/TemplateTest.cs
+
+
+	(2.- This is the point two!. This file is just after the end 
+	of the guidelines. Copy/paste it in another buffer. And keep 
+	reading.)
+
+	Save a copy of this file in the appropriate test subdirecty 
+	(see below), and replace all the [text] markers with 
+	appropriate code. Comments in the template are there to guide 
+	you. You should also look at existing tests to see how other 
+	people have written them. 
+
+	mcs/class/corlib/Test/System.Collections/CollectionBaseTest.cs 
+
+	is a small one that might help.
+
+	(3.- You reached the third point. And as expected, it's just 
+	here to tell you that the content of CollectionBaseTest.cs is 
+	after the TemplateTest.cs code at the end of these 
+	guidelines.)
+
+	The directory that will contain your new file depends on the
+	assembly/namespace of the class for which you are creating the
+	tests. Under mcs/class there is a directory for each assembly. 
+	In each assembly there is a Test directory, e.g. 
+	mcs/class/corlib/Test. In the Test directory there are 
+	sub-directories for each namespace in the assembly, e.g. 
+	mcs/class/corlib/Test/Sytem. Put your new test file in the 
+	appropriate sub-directory under Test for the class you are
+	testing.
+
+	Once your test class is complete, you need to add it to the
+	AllTests.cs file in the same directory as your new test. Add a 
+	call to "suite.AddTest()" passing the name of your new test 
+	class's suite property as the parameter.  You will see examples 
+	in the AllTests.cs file, so just copy and paste inside there.
+
+	Once all of that is done, you can do a 'make test' from the top 
+	mcs directory.  Your test class will be automagically included 
+	in the build and the tests will be run along with all the 
+	others.
+
+ <b> Tips </b>
+
+ <b> Provide an unique error message for Assert() </b>
+
+	Include an unique message for each Assert() so that when the 
+	assert fails, it is trivial to locate the failing one. 
+	Otherwise, it may be difficult to determine which part of the 
+	test is failing. A good way to ensure unique messages is to use 
+	something like #A01, #A02 etc.
+
+    	Bad:
+<pre>
+	AssertEquals("array match", compare[0], i1[0]);
+	AssertEquals("array match", compare[1], i1[1]);
+	AssertEquals("array match", compare[2], i1[2]);
+	AssertEquals("array match", compare[3], i1[3]);
+</pre>
+    	Good:
+<pre>
+	AssertEquals("#A01", compare[0], i1[0]);
+	AssertEquals("#A02", compare[1], i1[1]);
+	AssertEquals("#A03", compare[2], i1[2]);
+	AssertEquals("#A04", compare[3], i1[3]);
+</pre>
+	Once you used such a number in an Assert(), don't change it 
+	later on - people might use it it identify the test in bug 
+	reports or in mailing lists.
+
+ <b> Use AssertEquals() to compare things, not Assert(). </b>
+
+	Never compare two values with Assert() - if the test fails, 
+	people have no idea what went wrong while AssertEquals() 
+	reports the failed value.
+
+    	Bad:
+<pre>
+        Assert ("A01", myTicks[0] == t1.Ticks);
+</pre>
+    	Good:
+<pre>
+        AssertEquals ("A01", myTicks[0], t1.Ticks);
+</pre>
+
+ <b> Constructors </b>
+
+	When writing your testcase, please make sure to provide a 
+	constructor which takes no arguments:
+
+<pre>
+        public class DateTimeTest : TestCase
+        {
+
+                public DateTimeTest() : base ("[MonoTests.System.DateTimeTest]") {}
+                public DateTimeTest (string name): base(name) {}
+
+        	public static ITest Suite
+                {
+                        get {
+                                TestSuite suite = new TestSuite ();
+        			return suite;
+        		}
+        	}
+        }
+</pre>
+
+ <b> Namespace </b>
+
+	Please keep the namespace within each test directory
+	consistent - all tests which are referenced in the same
+	AllTests.cs must be in the same namespace. Of course you can
+	use subnamespaces as you like - especially for subdirectories
+	of your testsuite.
+	
+	For instance, if your AllTests.cs is in namespace "MonoTests"
+	and you have a subdirectory called "System", you can put all
+	the tests in that dir into namespace "MonoTests.System".
+
+ <b> Test your test with the microsoft runtime </b>
+
+	If possible, try to run your testsuite with the Microsoft
+	runtime on Windows and make sure all tests in it pass. This is
+	especially important if you're writing a totally new testcase
+	- without this check you can never be sure that your testcase
+	contains no bugs ....
+	
+	Don't worry if you're writing your test on Linux, other people
+	can test it for you on Windows.
+	
+	Sometimes you may discover that a test doesn't show the
+	expected result when run with the Microsoft runtime - either
+	because there is a bug in their runtime or something is
+	misleading or wrong in their documentation. In this case,
+	please put a detailed description of the problem to
+	mcs/class/doc/API-notes and do also report it to the list -
+	we'll forward this to the Microsoft people from time to time
+	to help them fix their documentation and runtime.

+* MonoDoc XML Tag Reference
+
+** Introduction
+
+<em>
+[This documentation is in progress.  Comments to
+<a href="mailto:jbarn@httcb.net">jbarn@httcb.net</a> and/or
+<a href="mailto:mono-docs-list@ximian.com">mono-docs-list@ximian.com</a>.]
+</em>
+
+MonoDoc XML, our format for multilingual API documentation stored outside of
+source files, is very similar to the output of Microsoft's csc /doc.  Minor
+alterations have been made to ease human parsing and hand-editing, but
+the majority of the tags are identical.  In fact, many of the descriptions
+and examples below are taken from the ECMA C# Language Specification with
+little or no alteration.
+
+This document provides a list of all available MonoDoc XML tags, with
+syntax and examples.  A complete example can be found in
+<a href="#appendix-a">Appendix A</a>, and both a <a href="#">DTD</a> and
+<a href="#">XSD schema</a> will be available very shortly.

+** Definitions and Examples
+
+*** <a name="c">&lt;c&gt;</a>
+
+This tag can be used to mark short, inline fragments of text that should 
+be considered source code or program output.  User agents should render 
+this tag in a special -- likely monospace -- font.  For larger sections, 
+use <a href="#code"><code>&lt;code&gt;</code></a>.
+
+**** Syntax
+
+<pre>
+&lt;c&gt;code or output text&lt;/c&gt;
+</pre>
+
+**** Example
+
+<pre>   
+&lt;remarks&gt;
+    Class &lt;c&gt;Point&lt;/c&gt; models a point in two-dimensional space.
+&lt;/remarks&gt;
+</pre>
+
+*** <a name="code">&lt;code&gt;</a>
+
+This tag can be used to mark one or more lines of text as source code or 
+program output.  User agents should render this tag in a special (likely 
+monospace) font, and preserve both whitespace and newlines.
+
+**** Syntax
+
+	<code>&lt;code&gt;source or program output&lt;/code&gt;</code>
+
+**** Example
+
+<pre>
+&lt;summary&gt;
+    This method changes the point's location by the given
+    x- and y-offsets.
+    &lt;example lang="C#"&gt;
+        A C# example:
+        &lt;code&gt;
+            Point p = new Point(3, 5);
+            p.Translate(-1, 3);
+            // p == (2, 8);
+        &lt;/code&gt;
+    &lt;/example&gt;
+&lt;/summary&gt;
+</pre>
+
+*** <a name="doc">&lt;doc&gt;</a>
+
+This tag is the root element of the documentation file.  It can contain 
+any number of &lt;type&gt; elements.
+
+**** Syntax
+
+<code>&lt;doc lang="language" assembly="assembly"&gt;typedocs&lt;/doc&gt;</code>
+
+<blockquote>
+<em>lang="language"</em><br />
+The two-letter ISO code that specifies what language the contained
+documentation is written in.
+</blockquote>
+
+**** Example
+
+<pre>
+&lt;doc lang="en"&gt;
+    &lt;type name="Graphics.Point"&gt;
+        &lt;!-- ... --&gt;
+    &lt;/type&gt;
+&lt;/doc&gt; 
+</pre>
+
+*** <a name="event">&lt;event&gt;</a>

+The name of the event being documented.
+</blockquote>
+		
+**** Example
+
+<pre>
+&lt;event name="Click"&gt;
+    &lt;summary&gt;
+        Occurs when the control is clicked.
+    &lt;/summary&gt;
+    &lt;data&gt;
+        The event handler receives an argument of type EventArgs
+        containing data related to this event.
+    &lt;/data&gt;
+    &lt;remarks&gt;
+        &lt;para&gt;The ControlStyles.StandardClick style must be set 
+        for this event to be raised.&lt;/para&gt;
+        &lt;para&gt;For more information about handling events, see 
+        Consuming Events.&lt;/para&gt;
+    &lt;/remarks&gt;
+&lt;/event&gt;
+</pre>
+
+*** <a name="example">&lt;example&gt;</a>
+
+This tag marks a section of text as an example, and optionally specifies 
+what programming language <code><a href="#code">&lt;code&gt;</a></code> portions of the example are written in.
+
+**** Syntax
+
+<code><example lang="language">example text and code</example></code>
+
+<blockquote>
+<em>lang="language"</em><br />
+(optional) The name of the programming language <code><a href="#code">&lt;code&gt;</a></code> blocks in this example
+use.  This information can be used by user agents to provide

+	x-coordinate.
+    &lt;/summary&gt;
+&lt;/field&gt;
+</pre>
+
+*** <a name="list">&lt;list&gt;</a>
+
+This tag is used to create a list or table of items.  It may contain a 
+<code>&lt;listheader&gt;</code> block to define the heading row of either a table or 
+definition list.  (When defining a table, only an entry for 'term' in the 
+heading need be supplied.)
+
+Each item in the list is specified with an <code>&lt;item&gt;</code> block.  When creating a 
+definition list, both <code>&lt;term&gt;</code> and <code>&ltdescription&gt;</code> must be specified.  
+However, for a table, bulleted list, or numbered list, only <code>&lt;description&gt;</code>
+need be specified.
+
+**** Syntax
+
+<pre>
+&lt;list type="bullet" | "number" | "table"&gt;
+   &lt;listheader&gt;
+       &lt;term&gt;term&lt;/term&gt;

+Either an item in a bullet or numbered list, or the definition of a <code>&lt;term&gt;</code>.
+</blockquote>
+
+**** Example
+
+<pre>
+&lt;list type="bullet"&gt;
+    &lt;item&gt;
+        &lt;description&gt;Item 1&lt;/description&gt;

+
+*** <a name="method">&lt;method&gt;</a>
+
+This tag is the overall containing tag for documenting a method.
+
+**** Syntax

+<code>&lt;method name="methodname"&gt;documentation&lt;/method&gt;</code>
+
+**** Example
+
+<pre>
+&lt;method name="op_Equality(Graphics.Point,Graphics.Point)"&gt;
+    &lt;summary&gt;
+        This operator determines whether two points have

+
+*** <a name="para">&lt;para&gt;</a>
+
+
+This tag is for use inside other tags such as <code>&lt;remarks&gt;</code> or <code>&lt;returns&gt;</code>, and 
+allows text to be structured into paragraphs.
+
+**** Syntax
+
+<code>&lt;para&gt;text&lt;/para&gt;</code>
+
+**** Example
+
+<pre>
+&lt;summary&gt;
+    &lt;para&gt;
+    This is the entry point of the &lt;c&gt;Point&lt;/c&gt; class testing 
+    program.
+    &lt;/para&gt;
+    &lt;para&gt;
+    This program tests each method and operator, and
+    is intended to be run after any non-trivial maintenance has
+    been performed on the &lt;c&gt;Point&lt;/c&gt; class.
+    &lt;/para&gt;
+&lt;/summary&gt;
+</pre>
+
+*** <a name="param">&lt;param&gt;</a>
+
+This tag is used to describe a parameter for a method, constructor, or

+
+<code>&lt;param name="name"&gt;description&lt;/param&gt;</code>
+	
+<blockquote>
+<em>name</em><br />

+&lt;summary&gt;
+    This constructor initializes the new Point to
+    (&lt;paramref name="xor" /&gt;,&lt;paramref name="yor" /&gt;).

+&lt;/property&gt;
+</pre>
+
+
+*** <a name="remarks">&lt;remarks&gt;</a>
+
+This tag contains extended discussion and information about a member or

+portions of Microsoft's documentation, but seems consistent with both 
+common usage, and, more importantly, NDoc convention.]</em>
+
+**** Syntax
+
+<code>&lt;remarks&gt;description&lt;/remarks&gt;</code>
+	
+**** Example
+
+<pre>
+&lt;type name="Graphics.Point"&gt;
+    &lt;summary&gt;
+        Models a point in a two-dimensional plane.
+    &lt;/summary&gt;
+    &lt;remarks&gt;
+        Herein I might have an extended discussion of
+        the validity of Cartesian coordinate systems,
+        with examples pro and con, and perhaps
+        some code.

+
+*** <a name="returns">&lt;returns&gt;</a>
+
+This tag is used to describe the return value of a method.
+
+**** Syntax

+<code>&lt;returns&gt;description&lt;/returns&gt;</code>
+
+**** Example
+
+<pre>
+&lt;method name="op_Inequality(Graphics.Point,Graphics.Point)"&gt;

+    &lt;/returns&gt;
+&lt;/method&gt;
+</pre>
+
+*** <a name="see">&lt;see&gt;</a>
+
+This tag allows a link to be specified within documentation text.  (Use 
+<code>&lt;seealso&gt;</code> to indicate links that should appear in a 'See Also' section.)
+
+**** Syntax
+
+<code>&lt;see cref="destination" /&gt;</code>
+
+<blockquote>
+<em>cref="destination"</em><br />
+A destination, such as a type or a member of a type.
+</blockquote>
+
+**** Example
+
+<pre>
+&lt;summary&gt;
+    This method changes the point's location to the given
+    coordinates.  This is an asinine way to insert a link,
+    but &lt;see cref="Equals(Object)" /&gt; to understand
+    how points are compared.
+&lt;/summary&gt;
+</pre>	
+
+*** <a name="seealso">&lt;seealso&gt;</a>
+
+This tag allows an entry to be generated for the 'See Also' section.  (Use

+
+This tag contains a short summary of a member or type, 
+often one sentence. <em>[jbarn: This differs from both the ECMA docs and

+common usage, and, more importantly, NDoc convention.]</em>
+
+**** Syntax
+
+<code>&lt;summary&gt;description&lt;/summary&gt;</code>

+* Updates
+
+	<b>Sep 20, 2001:</b> Microsoft has just announced some changes
+	to passport that are rather interesting.  This document
+	reflects the Passport system without taking into account the
+	new changes.
+
+	Read about it <a href="http://www.microsoft.com/presspass/features/2001/sep01/09-20passport.asp">here</a>.
+
+	For an analysis of security problems with passport, check <a
+	href="http://avirubin.com/passport.html">http://avirubin.com/passport.html</a>.
+	The bottom line is that you should not put any sensitive
+	information on passport.
+
+	I have received many comments from people, and I have updated
+	the page accordingly.  From removing incorrect statements, to
+	fixing typos, to include mentions to other software pieces.
+
+	I also corrected my statement about IIS and a trojan horse, I
+	should read a more educated press in the future.  My apologies
+	to Microsoft and its employees on this particular topic.  IIS
+	did not have a trojan horse built in.
+
+* Microsoft Hailstorm and Passport
+
+	Microsoft Passport is a centralized database hosted by
+	Microsoft that enhances the consumer experience with the Web
+	by providing a single logon system that they can use across a
+	number of participant web sites.
+
+	As you might know by now from our extensive <a
+	href="faq.html">FAQ</a>, the Mono project has nothing to do
+	with Microsoft Hailstorm or <a
+	href="http://www.passport.com">Microsoft Passport.</a>
+
+	Still a lot of people have asked us our opinion on them.
+
+** Passport
+
+	Passport is important not because of it being a breakthrough
+	technologically speaking, but because the company is in a
+	position to drive most people toward being suscribers of it.
+
+	At the time of this writing passport is required to use the
+	free mail service <a href="http://www.hotmail.com">Hotmail</a>
+	to get customized support for the <a
+	href="http://www.msn.com">MSN portal</a>, <a
+	href="http://msdn.microsoft.com">Microsoft Developers
+	Network</a> and according to the original announcement from
+	Microsoft <a href="http://www.americanexpress.com">American
+	Express</a> and <a href="http://www.ebay.com">EBay</a> will be
+	adopting it. 
+
+	There is already a <a
+	href="http://www.passport.com/Directory/Default.asp?PPDir=C&lc=1033">Large
+	list</a> of participating sites.
+
+	There are many current users of it and Microsoft will be
+	driving more users towards Passport as it <a
+	href="http://news.cnet.com/news/0-1003-200-6343275.html">integrates
+	it</a> in their upcoming release of Windows.  
+
+	Microsoft has also <a
+	href="http://www.passport.com/Business/JoinPassportNetwork.asp?lc=1033">developed
+	a toolkit</a> to enable current web merchants to integrate
+	their services with passport.
+
+	To the end user, there is a clear benefit: they only have to
+	log into a single network and not remember multiple passwords
+	across sites on the internet.  Companies that adopt passport
+	will have a competition advantage over those that dont.
+	Microsoft lists a list of <a
+	href="http://www.passport.com/Business/Default.asp?lc=1033">benefits</a>
+	to companies. 
+
+
+** The problems of Passport
+
+	There are a number of concerns that different groups have over
+	Passport.  Sometimes I have some, sometimes I do not.  But
+ 	overall, consumers and businesses can have better solutions.
+
+	<ul>
+		* <b>Single Point of Failure:</b> As more services and
+	 	components depend on remote servers, functionality can
+	 	grind to a halt if there is a failure on the
+	 	centralized Passport system.  
+
+		Such a failure was predicted, and we recently <a
+		href="http://news.cnet.com/news/0-1005-200-6473003.html">witnessed</a> 
+		got a lot of people worried.  
+
+		The outgage lasted for seven days.  Think what this
+	 	could do to your business.
+
+		* <b>Trust:</b> Not everyone trusts Microsoft to keep
+	 	their information confidential.  Concerns are not only
+	 	at the corporate level policy, but also the fact that
+	 	the source code for Microsoft products is not
+	 	available, means that trojans or worms could be built
+	 	into the products by malicious engineers.  
+
+		* <b>Security:</b> With a centralized system like
+	 	Passport, imagine the repercussions of a malicious
+	 	hacker gaining access to the Passport database.
+	 	Personal information and credit card information about
+	 	almost everyone using a computer could be stored there.
+
+		Hackers have already <a
+	 	href="http://slashdot.org/articles/00/10/27/1147248.shtml">broken
+	 	into Microsoft</a> in the past.  And the company was
+	 	unable to figure out for how long their systems had
+		been hacked. 
+
+		Security holes have been found in <a
+		href="http://slashdot.org/articles/00/04/14/0619206.shtml">IIS
+		in the past.</a>  If all the world's data is stored on
+		a central location, when a single security hole is
+		detected, it would allow an intruder to install a
+		backdoor within seconds into the corporate network
+		without people ever noticing. 
+
+		Microsoft itself has been recently hit by worms,
+		imagine if all your business depended on a single
+		provider for providing all or your authentication
+		needs
+	</ul>
+
+	Microsoft might or might not realize this.  The idea behind
+	Passport is indeed a good one (I can start to get rid of my
+	file that keeps track of the 30 logins and passwords or so
+	that I use across the various services on the net myself).
+
+** Alternatives to Microsoft Passport
+
+	An alternative to Microsoft Passport needs to take the above
+	problems into consideration.  Any solution of the form `We
+	will just have a competing offering' will not work.
+
+	The system thus has to be:
+
+	<ul>
+		* <b>Distributed:</b>  The entire authentication
+		system should not create an internet `blackout' in the
+		case of failure.
+
+	 	A distributed system using different software
+		platforms and different vendors would be more
+		resistent to an attack, as holes in a particular
+		implementation of the server software would not affect
+		every person at the same time.  
+
+		A security hole attack might not even be relevant to
+		other software vendors software.
+
+		* <b>Allow for multiple registrars:</b> Users should
+		be able to choose a registrar (their banks, local
+		phone company, service provider, Swiss bank, or any
+		other entity they trust.
+
+		* <b>Mandate good security measures:</b> As a
+		principle, only Open Source software should be used
+		for servers in the registrar, and they should conform
+		to a standard set of tools and software that can be
+		examined by third parties.
+	</ul>
+
+	An implementation of this protocol could use the DNS or a
+	DNS-like setup to distribute the information of users with the
+	possibility of replicating and caching public information
+	about the user.  
+
+	For instant messaging (another piece of the Hailstorm bit),
+	you want to use a non-centralized system like Sun's <a
+	href="http://www.jxta.org">JXTA</a>.  Some people mailed me to
+	mention Jabber as a messaging platform and other people
+	pointed out to the <a
+	href="http://java.sun.com/products/jms/">Java Message
+	Service</a>.   The JMS does support a number of very
+	interesting features that are worth researching.
+
+	It could also just use the user e-mail address as the `key' to
+	choose the registrar (msn.com, hotmail.com -> passport.com;
+	aol.com -> aol.passport.com; you get the idea).
+
+	The <a
+	href="http://www.soapware.org/xmlStorageSystem">xmlStorage</a>
+	idea from <a href="http://www.scripting.com">Dave Winer</a>
+	could be used to store the information.
+
+	A toolkit for various popular web servers could be provided,
+	authenticated and should be open sourced (for those of you who
+	think that a binary program would give more security and would
+	prevent people from tampering: you are wrong.  You can always
+	use a proxy system that "behaves" like the binary, and passes
+	information back and forth from the real program, and snoops
+	in-transit information).
+
+	Good cryptographers need to be involved in this problem to
+	figure out the details and the possible insecure pieces of a
+	proposal like this.
+
+** Implementation: In short
+
+	To keep it short: <b>DNS, JXTA, xmlStorage.</b>
+
+
+** Deploying it
+
+	The implementation of such a system should be a pretty
+	straightforward task once security cryptographers have
+	designed such a beast.  
+
+	The major problems are:
+
+	<ul>
+		* <b>People might just not care:</b> In a poll to US
+		citizens a couple of decades ago, it was found that
+		most people did not care about the rights they were
+		given by the Bill of Rights, which lead to a number of
+		laws to be passed in the US that eliminated most of
+		the rights people had.  
+
+		* <b>The industry will move way too slow:</b>
+		Microsoft's implementation is out in the open now: it
+		is being deployed, and soon it will be insinuated to
+		many, many users.  The industry needs to get together
+		soon if they care about this issue.
+
+		By the time the industry reacts, it might be too
+		late. 
+	</ul>
+
+** Passport and Mono
+
+	The .NET class libraries include a Passport class that
+	applications might use to authenticate with Passport.  Since
+	we do not have information at this point on the exact protocol
+	of Passport, it is not even feasible to implement it.
+
+	If at some point the information is disclosed, it could be
+	implemented.  
+
+	If a competing system to Passport existed, we could probably
+	hide all the authentication information to use a number of
+	different passport-like systems.
+
+	If a user does not want to use Passport at all, he could
+	always turn it off (or completely remove the class from the
+	library).  After all, this is free software.
+
+	Currently, we are too far from the point where this is a real
+	issue. 
+
+** Passport and endangering Open Source.
+
+	A few people have said: `Mono will allow Passport to be
+	available for Linux and that is bad'.  This is plain
+	misinformation.
+
+	Currently, you can obtain Passport for Linux from Microsoft
+	itself and deploy it today on your Web server.  Mono does not
+	even enter the picture here.  Go to passport.com and download
+	the toolkit and you will see with your own eyes that passport
+	is <B>already</b> available for Linux. 
+
+** Disclaimer
+
+	This is just a group of personal thoughts of mine that I have
+	placed here because I get asked this question a lot lately.
+	The views of this page are not a statement from my employer
+	(Ximian, Inc).
+
+	This is not part of Mono.  We are not trying to deal with this
+	problem. 
+
+	Nat Friedman (Ximian's co-founder) has his own ideas on how a
+	competing system to Passport could be designed, but I will let
+	<a href="http://www.nat.org/">him</a> post his own story.

+* How to port Mono to your preferred architecture
+
+** Endian, 64 bits and unaligned access issues
+
+	The first thing to do is to check that the metadata handling
+	library works on your target processor. You may use the disassembler
+	on simple programs and check that you get sensible results
+	(assuming it compiles at all on your system:-).
+
+	The main issue is to write macros that read unaligned
+	little endian shorts/ints/longs/float/doubles: look into
+	mono/metadata/endian.h. There may be other spots in the code that are
+	unsafe at reading/writing to some datatypes that require special
+	alignment, but there should be few such issues and they need to be fixed.
+
+	Once this stuff is sorted out, you should be able to run the interpreter
+	on simple programs that don't require delegates, P/Invoke functions etc..
+
+** Generating assembly bytecodes for the target processor
+
+	Next, you need to provide the support code for generating assembly bytecode
+	for your target platform (in mono/arch/{ppc,sparc,alpha,*}).
+	The code should be more or less like the code in x86-codegen.h:
+	macros that produce fast in-line code. You don't need to provide
+	code to create every possible code, at first, just the code to
+	create trampolines and execute them is fine (you'll need to research
+	how the call convention works on your platform): that would be, for
+	example, the prolog and epilog code in a function, code to pass function
+	parameters and deal with the return value and so on.
+
+	libffi in gcc or the xptcall sources in mozilla may be helpful to
+	understand how the calling convention works, if you can't find a specification.
+	You'd need a processor manual to know how to create the assembly binary data.
+	This requires a lot of reading if you're not familiar with the assembly for your
+	target platform. Manuals for many processors are available as PDF files on the
+	web site of the respective vendors. Note that some processors require you to
+	flush the I-cache before executing the code: have a look at how the same thing is
+	done in GNU lightning.
+
+** Getting the interpreter to work
+
+	Once you can generate binary code, you can start working on a
+	mono_create_trampoline() function for your platform: this function will receive
+	a MonoMethod that describes the arguments and the return type of a C function
+	and will create the code to call such function. When this function is complete
+	you'll be able to run more sample programs, that use System.IO, P/Invoke
+	functions etc.
+
+	To support delegates you'll need to write a mono_create_method_pointer()
+	function that creates a native function: this can be used to call the
+	method using the runtime's calling convention (it's basically the reverse
+	of mono_create_trampoline()).
+
+** The final step: porting the JIT
+
+	At this point you'd need to have a more complete code generation header file
+	and you can start writing the machine description file for the monoburg
+	system. This code (jit/tesjit.c) will require some machine specific tweaks,
+	but hopefully all you have to do is create the grammar that emit assembly
+	code from the IR tree. Work is at the early stages also for x86 on this stuff
+	as we are still testing various solutions: you'd want to read about burg-like
+	code-generator generators (the LCC book is a good starting point).

+
+* The Mono Project
+
+** Background.
+
+	The GNOME project goal was to bring missing technologies to
+	Unix and make it competitive in the current market place for
+	desktop applications.  We also realized early on that language
+	independence was important, and that is why GNOME APIs were
+	coded using a standard that allowed the APIs to be easily
+	wrapped for other languages.  Our APIs are available to most
+	programming languages on Unix (Perl, Python, Scheme, C++,
+	Objective-C, Ada). 
+
+	Later on we decided to use better methods for encapsulating
+	our APIs, and we started to use CORBA to define interfaces to
+	components. We complemented it with policy and a set of
+	standard GNOME interfaces for easily creating reusable,
+	language independent components, controls and compound
+	documents.  This technology is known as <a
+	href="http://developer.ximian.com/tech/bonobo.html">Bonobo</a>.
+	Interfaces to Bonobo exist for C, Perl, Python, and
+	Java.
+
+	CORBA is good when you define coarse interfaces, and most
+	Bonobo interfaces are coarse.  The only problem is that
+	Bonobo/CORBA interfaces are not good for small interfaces.
+	For example, an XML parsing Bonobo/CORBA component would be
+	inefficient compared to a C API.
+
+** Another explanation
+
+	I recently explained our motivations to Dave Winer, and he posted
+	it <a
+	href="http://scriptingnews.userland.com/stories/storyReader$1275">here</a>
+
+** Microsoft's .NET
+
+	The Microsoft .NET initiative is confusing because it is a
+	company wide effort that ranges from development tools to end
+	user applications.  .NET is a branding formative that
+	has been applied to:
+
+	<ul>
+		* The .NET development platform, a new platform for
+		  writing software.
+
+		* Web services.
+
+		* Microsoft Server Applications.
+
+		* New tools that use the new development platform.
+
+		* Hailstorm, the Passport centralized single-signon
+		  system that is being integrated into Windows XP.
+
+	</ul>
+
+	Mono is an implementation of the .NET development platform.
+
+** The Common Language Infrastructure platform. 
+
+	Microsoft has created a new development platform.  The
+	highlights of this new development platform are:
+
+	<ul>
+		* A runtime environment that provides garbage
+		  collection, threading and a virtual machine
+		  specification (The Virtual Execution System, VES)
+
+		* A comprehensive class library.  
+
+		* A new language, C#.  Very similar to Java,  C#
+		  allows programmers to use all the features available
+		  on the .NET runtime.
+
+		* A language specification that compilers can
+		  follow if they want to generate classes and code
+		  that can interoperate with other programming
+		  languages (The Common Language Specification: CLS)
+	</ul>
+
+	The Common Language Infrastructure platform is similar to the
+  	goals we had in GNOME of giving language independence to
+  	programmers.  It is more mature, documented, larger in scope,
+  	and has a consistent design.
+
+	Any API that is written using a CLS provider language can be
+  	used by any language that is a CLS consumer.  Compilers
+  	generate code in a format called Common Intermediate Language
+  	(CIL) which is an intermediate representation of a compiled
+  	program and is easy to compile to native code or compiled
+  	using Just-in-Time (JIT) engines.  The restrictions placed by
+  	the runtime on the CIL byte codes ensures that it is possible
+  	to do a good job at optimizing the code in a JIT compiler.
+
+	There is not really a lot of innovation in this platform: we
+	have seen all of these concepts before, and we are all
+	familiar with how these things work.
+
+	What makes the Common Language Infrastructure development
+  	platform interesting is that it is a good mix of technologies
+  	that have been nicely integrated.
+
+	The .NET development platform is essentially a new foundation
+	for program development that gives Microsoft a room to grow
+  	for the coming years. 
+
+** ECMA standards.
+
+	Microsoft has submitted the
+  	specifications of C#, the runtime, the metadata and the
+  	other various bits of the .NET development platform to the
+  	<a href="http://www.ecma.ch">ECMA</a> for standarization.
+
+	You can get a copy of the specifications submitted to ECMA
+	from: <a href="http://www.dotnetexperts.com/ecma">http://www.dotnetexperts.com/ecma</a>
+
+** Mono: an Open Source Common Language Infrastructure implementation. 
+
+	Ximian has begun work on Mono, a project that aims to bring
+  	the Common Language Infrastructure platform to free systems.  
+
+	When the GNU project was launched, they picked the best
+  	operating system that was available out there, and they
+  	began to clone it: Unix.
+
+	The .NET development platform is a very rich, powerful, and
+  	well designed platform that would help improve the free
+  	software development platform.  Just like the GNU project
+  	began to clone Unix sixteen years ago, we will be cloning the
+  	.NET development platform because it is a great platform to
+  	build on.
+
+** What makes up Mono?
+
+	There are various pieces that will make up Mono:
+
+	<ul>
+		* A C# compiler.
+
+		* The Virtual Execution System: that will have the
+  		  Just-in-Time compiler, garbage collector, loader,
+  		  threading engine.
+
+		  A byte code interpreter will be provided for quickly
+  		  porting Mono to new systems and debugging the JIT
+		  purposes, but it is not intended to be the ideal
+		  execution environment.
+
+		* An implemenation of the .NET class library.
+
+		* Visual development tools. 
+
+		* A CIL GCC frontend.
+	</ul>
+
+** Why use GNOME components?
+
+	GNOME is an umbrella project that consists of infrastructural
+	components (GUI toolkit, XML libraries, CORBA implementation,
+	printing architecture, imaging system), a desktop environment,
+	and productivity applications.
+
+	The GNOME infrastructural components can be used to quickly
+	implement various pieces of the class libraries without reinventing
+	the wheel, and since all those components are licensed under
+	the terms of the GNU LGPL it is a perfect fit.  
+
+	Libart will be used to implement the Drawing.2D API; Gtk+ and
+	the GNOME libraries will be used to implement the WinForms
+	API and of course Glib and libxml will be used in various
+	places.

+
+Hey!
+
+   July 12 snapshots of class libraries, the compiler and the mono
+runtime are available.
+
+New on this release:
+
+    * Runtime (module: mono)
+
+	The beginning of a simple interpreter that Paolo started
+	workign on (can run really simple .NET programs).
+
+	Disassembler copes with more elements of the binary format and
+	more tokens are decoded.  Paolo is working now on moving some
+	of these to the metadata library. 
+
+	More tables are dumped.
+
+    * Class libraries (module: mcs/class)
+
+	Many new more classes are in from Joe, Vladimir, Jeff, Sean
+	and yours truly.
+
+	Sean fixed the build process, and it is now possible to
+	compile with a single command the assemblies.  We will be
+	revisiting this mechanism in the future to compile per-OS
+	assemblies (ie, Unix, Windows, MacOS, etc).
+
+     * Compiler (module mcs/mcs)
+
+	Not much done this week, just a few fixes here and there, and
+	more work to make it easy to compiler.
+
+     * Documentation (module: mono/doc)
+
+	All the changes to the web site are there for your browsing
+	pleasure.  We still need to integrate the status system in
+	there.

+* The Mono runtime
+
+	The Mono runtime implements a JIT engine for the CIL virtual
+	machine (as well as a byte code interpreter, this is to
+	quickly port it to new systems), the class loader, the garbage
+	collector, threading system and metadata access libraries.
+
+	We currently have two runtimes:
+
+	<ul>
+		* <b>mono:</b> The Just In Time compiler implemented
+	 	  using a BURS instruction selector.  We only support
+		  x86 machines in the JIT engine at this point.
+	
+		* <b>mint:</b> The Mono interpreter.  This is an
+		  easy-to-port runtime engine.
+	</ul>
+
+	Currently we are using the Bohem conservative garbage
+	collector, but we working on incorporating the ORP GC engine. 
+
+** Executing MSIL/CIL images
+
+	The code will load an executable and map the references to
+	external assemblies to our own version of the assemblies on
+	Linux.
+
+	Our roadmap looks like this, this has been updated as of
+	<b>Dec 18, 2001</b>:
+
+	<ul>
+
+		* Milestone 1: <b>Done</b> Fully read and parse all CIL byte-codes
+		  and metadata tokens (ie, a disassembler).  
+
+		* Milestone 2: <b>Done</b> Complete an interpreter for CIL byte
+		  codes.  This interpreter can be used temporarly to
+		  run CIL byte code on a system where no JIT is
+		  available.
+
+		* Milestone 3: <b>Done</b>Define an <i>lburg</i>-like
+		  instruction selector for the JITer for Intel.
+
+		* Milestone 4: <b>Done</b> Implement JITer.  This is where our
+		  current efforts are focused on, the JITer currently runs
+		  all of the code we have tested on it.  The major limitation
+		  is that our class libraries are not complete, and hence not
+		  every application can be ran.
+
+		* Milestone 5: Port of the JITer to non IA32 systems.
+	</ul>
+
+	A setup similar to the Kaffe JIT engine will be used to
+	layout the code to support non-IA32 architectures.  Our work
+	will be focused on getting a IA32 version running first.  
+
+	The JIT engine works on Linux and Win32, although you
+	will need to install the CygWin32 development tools to get a
+	Unix-like compilation environment (mostly we use GNU make in 
+	a few of the makefiles).
+
+** JIT Engine (<b>updated, July 8th, 2002</b>)
+
+	The JIT engine uses a code-generator generator approach for
+	compilation.  Given the properties of CIL byte codes, we can
+	take full advantage of a real instruction selector for our
+	code generator. 
+
+	The JIT engine implements a number of optimizations:
+
+	<ul>
+		* Opcode cost estimates (our architecture allows
+	 	  us to generate different code paths depending
+		  on the target CPU dynamically).
+		  
+		* Inlining.
+
+		* Constant folding.  
+
+		  Although compilers typically do
+		  constant folding, the combination of inlining with
+		  constant folding gives some very good results.
+
+		* Linear scan register allocation.  In the past,
+		  register allocation was our achilles heel, but now 
+		  we have left this problem behind.
+	</ul>
+
+	There are a couple of books that deal with this technique: "A
+	Retargetable C Compiler" and "Advanced Compiler Design and
+	Implementation" are good references.  You can also get a
+        technical description of <a
+        href="http://research.microsoft.com/copyright/accept.asp?path=http://www.research.microsoft.com/~drh/pubs/iburg.pdf&pub=ACM">lbrug</a>.
+
+	A few papers that describe the instruction selector:
+
+	<ul>
+		* <a href="http://research.microsoft.com/copyright/accept.asp?path=http://www.research.microsoft.com/~drh/pubs/interface.pdf&pub=wiley">A code generation interface for ANSI C</a>
+
+
+		* <a href="http://research.microsoft.com/copyright/accept.asp?path=http://www.research.microsoft.com/~drh/pubs/iburg.pdf&pub=ACM">Engineering efficient code generators using tree matching and dynamic programming.</a>
+
+	</ul>
+
+** Future plans
+
+	We are evaluating the future directions for the JIT engine:
+	both from our needs (optimizations like inlining, better register allocation,
+	instruction scheduling, and porting to other CPUs).
+
+	We have not yet decided how we will evolve the JIT engine.  We
+	might just upgrade our current architecture, and provide optimizations as
+	an extra layer.
+
+** Garbage Collection
+
+	Currently we are using the Boehm conservative GC.  Although our plans 
+	are to move to the Intel ORP GC engine, our plans on a next generation
+	dual-JIT engine have to be taken into account.
+
+	We will be using the Intel ORP GC engine as it provides a precise
+	garbage collector engine, similar to what is available on the
+	.NET environment. 
+
+	Although using a conservative garbage collector like Bohem's
+	would work, all the type information is available at runtime,
+	so we can actually implement a better collector than a
+	conservative collector.

+	</ul>
+
+** IO and threading
+
+	The ECMA runtime and the .NET runtime assume an IO model and a
+	threading model that is very similar to the Win32 API.  
+
+	Dick Porter has been working on the Mono abstraction layer
+	that allows our runtime to execute code that depend on this
+	behaviour.

+	</ul>
+
+** PInvoke
+
+	PInvoke is the mechanism we are using to wrap Unix API calls
+	as well as talking to system libraries.
+
+	Initially we used libffi, but it was fairly slow, so we have
+	reused parts of the JIT work to create efficient PInvoke trampolines. 
+
+** Remoting
+
+	Mono has support for remoting and proxy objects, just like
+	.NET does.  The runtime provides these facilities.
+
+** Porting
+
+	If you are interested in porting the Mono runtime to other
+	platforms, you might find the pre-compiled <a
+	href="archive/mono-tests.tar.gz">Mono regression test
+	suite</a> useful to debug your implementation.
+
+* COM and XPCOM
+
+	We plan on adding support for XPCOM on Unix and COM on Microsoft
+	Windows later in our development process.

+* Testing
+
+	Testing is an important part of the Mono project: every one of its
+	three major components has a test suite tailored for its needs.  This
+	is very helpful, because in the course of developing the software it
+	is very common to introduce bugs in existing code.  A test suite
+	helps us fix the bugs as soon as they are introduced.
+
+** Class Library Tests
+
+	All classes in Mono libraries should have comprehensive unit test
+	suites to go with them. Unit testing is a software engineering
+  	methodology that makes it easier to build correct code. Every
+  	method in every class should have a set of tests to verify
+  	that they work correctly. Mono also needs a testing framework
+	to make it easy to write and run lots of tests. 
+
+	Try <a href="http://nunit.sourceforge.net">NUnit</a>
+
+	Why do unit testing? It becomes simple to run automated tests
+	for the whole library. Unit tests are a safety net - you can
+	change part of the code and verify that you haven't broken
+	anything. Ideally, tests are written before the actual library
+	code itself. And every time a bug is discovered, a test should
+	be written to demonstrate the bug and its fix. Then, if
+	you ever reintroduce the bug, you will know immediately. For
+	more info, read <a
+	href="http://junit.sourceforge.net/doc/testinfected/testing.htm">
+	JUnit Test Infected: Programmers Love Writing Tests</a>.
+
+
+** Getting Started
+
+	We welcome all contributions to the Class Libary Test Suite.
+
+	There is information to help you get started in CVS at
+	mcs/class/doc/NUnitGuidelines. Once you have written your test, please
+	post it to <a href="mailing-lists.html">mono-list</a>.
+
+	Someone will make sure to add the file or apply the patch as
+	appropriate. If you plan to be an on-going contributor and
+	would like to get cvs account, email <a href="mailto:miguel@ximian.com">miguel</a>.
+
+	Normally, after you send a couple of well-written new files
+	and/or patches to the list, you will be given cvs access.

+* Tools
+
+	We need a number of tools to make people productive using a
+	Mono-based solution.  Some of these tools can be developed on
+	Windows before Mono is fully finished.
+
+	All of these tools should be written using C#.  
+
+	For the tools that are typically command line tools: Try to
+	write these as components that could load their input from
+	streams or collections of streams, and implement the command
+	line tools as wrappers around those classes.
+
+	For example, we will be making the C# compiler a component
+	that could be reused by applications that might have a use for
+	the various bits of the compiler (either to embed the
+	compiler, or reuse the code generator part of it).  
+
+	This is important so that these components (compiler,
+	assembler, linker, etc) can be integrated later into the
+	visual development environment (hopefully with the help of the
+	SharpDevelop hackers). 
+
+TODO=ilasm,IL Assembler
+** IL Assembler.
+
+	This assembler should basically take as input a file
+	containing IL bytecodes as specified in the `Partition II' of
+	the ECMA spec, and produce a binary file.
+
+TODO=al,Assembly Linker
+** Assembly Linker.
+
+	This tool is used to construct assemblies, which are basically
+	deployment units for CLI executables.
+
+TODO=debugger,Debugger
+** Debugger
+
+	We will need a debugging API to debug CLI applications and
+	then a debugger component that can be used in an IDE
+	environment.
+
+TODO=ide,Integrated Development Environment
+** Integrated Development Environment
+
+	There is already a project to create a C# development
+	environment: <a
+	href="http://www.icsharpcode.net/OpenSource/SD/default.asp">SharpDevelop</a>.
+	People should work with the SharpDevelop hackers to produce a
+	unified development environment.
+
+	Please work with the SharpDevelop hackers to build a good IDE.
+	We will work on creating an embedable compiler component and
+	an embeddable debugger component that can be used withing
+	SharpDevelop
+
+TODO=hbrowser,Help Browser
+** Help Browser
+
+	We need a good help browser that can be used to browse
+	documentation.  Ideally this help browser can accept as input
+	XML Docbook input and an assorted set of file formats
+	(Microsoft Help, Unix manual pages, Unix Info pages)
+
+	Look at the GNOME DevHelp for a good set of ideas on how to
+	implement this.

+* System.Windows.Forms
+
+	System.Windows.Forms eventually will support multiple
+	toolkits.  Ximian will be delivering a product that will allow
+	for System.Windows.Forms applications to integrate with GNOME
+	through Gtk and MacOS X using Cocoa.
+
+	There are no current plans to support embedded devices, but
+	Gtk/FrameBuffer is an option.  If you have suggestions or
+	recommendations, please let us <a
+	href="mailto:mono-hackers-list@ximian.com">let us know</a>
+
+* Contributing
+
+	Currently Ximian developers are busy making our JIT engine
+	feature complete, and dealing with the low-level details of
+	the Mono runtime.
+
+	If you are interested in contributing, you can start stubbing
+	out classes and providing enumerations.  That will help us
+	significantly when we start working on the actual bindings.  
+
+	Christian Meyer is currently organizing this effort.
+
+* System.Drawing
+
+	Using existing libraries to implement some of the functionality required
+
+	<ul>
+		* gdk-pixbuf is a generic image loader that loads an image
+		  and leaves it into an RGB buffer.  It hides all the details
+		  about what image file format is being loaded.
+
+		* Libart is a general framework for rendering RGB/RGBA
+		  buffers into RGB buffers and rendering postscript-like paths into
+		  RGB/RGBA buffers.
+	</ul>
+
+	We want to use gdk-pixbuf as the image loader for the image
+	classes, and then we need operations to render that into the
+	windowing system (Gtk+, MacOS, etc).  But notice how there is
+	very little dependnecies in Gdk-pixbuf on gtk, and libart has
+	none.
+
+	They are pretty independent from a windowing system
+	(gdk-pixbuf comes with some "helper" routines for rendering
+	data into a pixmap and to load pixmaps into RGB buffers).
+
+	A few things to keep in mind:
+	
+	<ul>
+	
+		* gdk-pixbuf can be used to load images for Gtk+,
+		  MacOS X and Windows, it should be pretty portable,
+		  although we might need in the future to back-port
+		  some new features from Gtk head. 
+
+		* Libart is probably only going to be used with X11,
+		  as the MacOS X provides the same features in Quartz,
+		  and Win32 *probably* has that in GDI+.  If not, we
+		  should use libart in Win32 as well (or for older
+		  Windows systems).
+	</ul>
+
+* Directory Layout
+
+        System.Drawing  (assembly directory)
+                System.Drawing.Blah
+                        Common code for "Blah"
+                        Stubs for "Blah" to ease ports.
+
+                Gtk
+                        System.Drawing.Blah.
+                                Gtk ports of "System.Drawing.Blah"
+                MacOS
+                        System.Drawing.Blah
+                                MacOS ports of "System.Drawing.Blah"
+                Win32
+                        System.Drawing.Blah
+                                Win32 ports of "System.Drawing.Blah"
+
+	Then we use nant targets to include/exclude the right set of
+	files to create the assembly.
+
+* Open questions:
+
+	I believe that the graphics contexts that are used to render
+	can accept either libart-like rendering operations and
+	X11-like rendering operations.  This complicates matters, but
+	I am not sure.  Someone needs to investigate this.

+Exception implementation (jit):
+===============================
+
+Stack unwinding:
+================
+
+We record the code address (start_address, size) of all methods. That way it is
+possible to map an instruction pointer (IP) to the method information needed
+for unwinding the stack:
+
+We also save a Last Managed Frame (LMF) structure at each call from managed to
+unmanaged code. That way we can recover from exceptions inside unmanaged code.
+
+void handle_exception ((struct sigcontext *ctx, gpointer obj)
+{
+        if (ctx->bp < mono_end_of_stack) {
+	        /* unhandled exception */
+	        abort ();
+	}
+
+	info = mono_jit_info_table_find (mono_jit_info_table, ctx->ip);
+
+	if (info) { // we are inside managed code
+
+		if (ch =  find_catch_handler ())
+			execute_catch_handler (ch, ctx, obj); 
+		
+		execute_all_finally_handler ();
+
+		// restore register, including IP and Frame pointer
+		ctx = restore_caller_saved_registers_from_ctx (ji, ctx);
+
+		// continue unwinding
+		handle_exception (ctx, obj);
+
+	} else {
+
+	        lmf = get_last_managed_frame ();
+		
+		// restore register, including IP and Frame pointer
+		ctx = restore_caller_saved_registers_from_lmf (ji, lmf);
+		
+		// continue unwinding
+		handle_exception (ctx, obj);
+	}
+}
+
+
+Code generation:
+================
+
+leave: is simply translated into a branch to the target. If the leave
+instruction is inside a finally block (but not inside another handler)
+we call the finally handler before we branch to the target.
+
+finally/endfinally: is translated into subroutine ending with a "return"
+statement. The subroutine does not save EBP/ESP, because we need access to the
+local variables of the enclosing method. We have to use a "call"
+instruction to execute such finally handlers. This makes it possible to
+execute them inside the stack unwinding code.
+
+throw: we first save all regs into a sigcontext struct (we pass the
+exception object in register ECX), and then call the stack unwinding
+code.
+
+catch handler: receives the exception object in ECX. They store that
+object into a local variable, so that rethrow can access the object.

+* GC issues you need to be careful about when hacking on the mono runtime.
+
+mono currently uses the Boehm garbage collection library. This is a conservative
+GC package: this means that the memory is searched for possible memory references
+to chunks allocated with the GC. Not all the memory is searched, but only the memory
+allocated with the GC itself (unless you use the 'atomic' variant of the allocation 
+routines), the stack and global variables. Also, if the last reference to an object 
+is stored in an area of themory that is not searched, the object may be freed resulting 
+in memory corruption ind segfaults.
+
+In particular, memory allocated with system's malloc() is not searched, so you need to be
+careful NOT to store object references in memory allocated with malloc() (unless you are sure
+that the object reference will be live at the same time in some other area under the control 
+of the GC (on the stack or in a global variable, for example). Since g_malloc()
+ultimately calls system malloc() the data structures in GLib are not safe to
+use to store object references.
+
+Occasionally, you'll need to store some object reference from C code: in this case, 
+you must make sure that the store location is searched by the GC. You can safely
+use thread local storage areas, global variables, stack variables. If you need a more 
+complicated data structure, you can use a hash table: MonoGHashTable.
+This hash table has the same interface as GHashTable from GLib, just stick the "mono_"
+prefix in function calls and the "Mono" prefix in the hash table type name.
+This hash table ensures that object references stored in it are tracked by the GC, as long
+as the pointer to the hash is tracked itself.
+
+Other data structures that are allocated with the GC and are safe to use to store pointers
+to GC-allocated memory, are MonoDomain (keeps track of many domain specfic objects)
+and MonoVTable (referenced by MonoDomain: keeps track of the static data of a type
+since that can hold references to objects).

+Any other type that has a matching C structure representation, should use
+a pointer to the struct instead of a generic MonoObject pointer.
+
+Instance methods that are internal calls will receive as first argument
+the instance object, so you must account for it in the C method signature:
+
+	[MethodImplAttribute(MethodImplOptions.InternalCall)]
+	public extern override int GetHashCode ();
+
+becaomes:
+
+	gint32 ves_icall_System_String_GetHashCode (MonoString *this);
+
+
+
+* How to hook internal calls with the runtime
+
+Once you require an internal call in corlib, you need to create a C
+implementation for it and register it in a static table in metadata/icall.c.
+Add an entry in the table like:
+
+	"System.String::GetHashCode", ves_icall_System_String_GetHashCode,
+
+Note that you need to include the full namespace.name of the class.
+If there are overloaded methods, you need also to specify the signature
+of _all_ of them:
+
+	[MethodImplAttribute(MethodImplOptions.InternalCall)]
+	public extern override void DoSomething ();
+	[MethodImplAttribute(MethodImplOptions.InternalCall)]
+	public extern override void DoSomething (bool useful);
+
+should be mapped with:
+
+	"Namespace.ClassName::DoSomething()", ves_icall_Namespace_ClassName_DoSomething,
+	"Namespace.ClassName::DoSomething(bool)", ves_icall_Namespace_ClassName_DoSomething_bool,

+Register Allocation
+===================
+
+The current JIT implementation uses a tree matcher to generate code. We use a
+simple algorithm to allocate registers in trees, and limit the number of used
+temporary register to 4 when evaluating trees. So we can use 2 registers for
+global register allocation.  
+
+Register Allocation for Trees
+=============================
+
+We always evaluate trees from left to right. When there are no more registers
+available we need to spill values to memory. Here is the simplified algorithm.
+
+gboolean 
+tree_allocate_regs (tree, exclude_reg)
+{
+	if (!tree_allocate_regs (tree->left, -1))
+	        return FALSE;
+  
+	if (!tree_allocate_regs (tree->right, -1)) {
+	  
+		tree->left->spilled == TRUE;
+
+		free_used_regs (tree->left);
+
+		if (!tree_allocate_regs (tree->right, tree->left->reg))
+			return FALSE;
+	}
+
+	free_used_regs (tree->left);
+	free_used_regs (tree->right);
+
+	/* try to allocate a register (reg != exclude_reg) */
+	if ((tree->reg = next_free_reg (exclude_reg)) != -1)
+	        return TRUE;
+  
+	return FALSE;
+}
+
+The emit routing actually spills the registers:
+
+tree_emit (tree)
+{
+
+	tree_emit (tree->left);
+
+	if (tree->left->spilled)
+		save_reg (tree->left->reg);
+
+	tree_emit (tree->right);
+	
+	if (tree->left->spilled)
+		restore_reg (tree->left->reg);
+
+
+	emit_code (tree);
+}
+
+
+Global Register Allocation

+TODO.

+Just some thoughts for the JITer:
+
+General issues:
+===============
+
+We are designing a JIT compiler, so we have to consider two things:
+
+- the quality of the generated code
+- the time needed to generate that code
+
+The current approach is to keep the JITer as simple as possible, and thus as
+fast as possible. The generated code quality will suffer from that.
+
+Register Allocation:
+====================
+
+With lcc you can assign a fixed register to a tree before register
+allocation. For example this is needed by call, which return the value always
+in EAX on x86. The current implementation works without such system, due to
+special forest generation.
+
+Different Register Sets:
+========================
+
+Most processors have more that one register set, at least one for floating
+point values, and one for integers. Should we support architectures with more
+that two sets? Does someone knows such an architecture?
+
+64bit Integer Values:
+=====================
+
+I can imagine two different implementation. On possibility would be to treat
+long (64bit) values simply like any other value type. This implies that we
+call class methods for ALU operations like add or sub. Sure, this method will
+be be a bit inefficient.
+
+The more performant solution is to allocate two 32bit registers for each 64bit
+value. We add a new non terminal to the monoburg grammar called "lreg". The
+register allocation routines takes care of this non terminal and allocates two
+32 bit registers for them.
+
+Forest generation:
+==================
+
+Consider the following code: 
+
+OPCODE:		STACK		LOCALS
+LDLOC.0		(5)		[5,0]
+LDC.1		(5,1)		[5,0]
+STLOC.0		(5)		[1,0]
+STLOC.1		()		[1,5]
+
+A simple forest generation generates: 
+
+STLOC.0(LDC.1)
+STLOC.1(LDLOC.0)
+
+Which is wrong, since it stores the wrong value (1 instead of 5). Instead we
+must generate something like:
+
+STLOC.TMP(LDLOC.0)
+STLOC.0(LDC.1)
+STLOC.1(LDLOC.TMP)
+
+Where STLOC.TMP saves the value into a new temporary variable. 
+
+We also need a similar solution for basic block boundaries when the stack depth
+is not zero. We can simply save those values to new temporary values. Consider
+the following basic block with one instruction:
+
+LDLOC.1 
+This should generate a tree like: 
+
+STLOC.TMP(LDLOC.1) Please notice that an intelligent register allocator can
+still allocate registers for those new variables.
+
+DAG handling:
+=============
+
+Monoburg can't handle DAGs, instead we need real trees as input for
+the code generator. So we have two problems:
+
+1.) DUP instruction: This one is obvious - we need to store the value
+into a temporary variable to solve the problem.
+
+2.) function calls: Chapter 12.8, page 343 of "A retargetable C compiler"
+explains that: "because listing a call node will give it a hidden reference
+from the code list". I don't understand that (can someone explain that?), but
+there is another reason to save return values to temporaries: Consider the
+following code:
+
+x = f(y) + g(z); // all functions return integers
+
+We could generate such a tree for this expression: STLOC(ADD(CALL,CALL))
+
+The problem is that both calls returns the value in the same register,
+so it is non trivial to generate code for that tree. We must copy one
+register into another one, which make register allocation more complex.
+The easier solution is store the result of function calls to
+temporaries. This leads to the following forest:
+
+STLOC(CALL)
+STLOC(CALL)

+
+Possible Optimisations:
+=======================
+
+Miguel said ORP does some optimisation on IL level, for example moving array
+bounds checking out of loops:
+
+for (i = 0; i < N; i++) { check_range (a, i); a [i] = X; }
+
+id transformed to:
+
+if (in_range (a, 0, N)) { for (i = 0; i < N; i++) a[i] = X; }  
+else for (i = 0; i < N; i++) { check_range (a, i); a [i] = X; }
+
+The "else" is only to keep original semantics (exception handling).
+
+We need loop detection logic in order to implement this (dominator tree).
+
+AFAIK CACAO also implements this.

+Howto trigger JIT compilation
+=============================
+
+The JIT translates CIL code to native code on a per method basis. For example
+if you have this simple program:
+
+public class Test {
+	public static void Main () {		
+		System.Console.WriteLine ("Hello");
+	}
+}
+
+the JIT first compiles the Main function. Unfortunately Main() contains another
+reference to System.Console.WriteLine(), so the JIT also needs the address for
+WriteLine() to generate a call instruction.
+
+The simplest solution would be to JIT compile System.Console.WriteLine()
+to generate that address. But that would mean that we JIT compile half of our
+class library at once, since WriteLine() uses many other classes and function,
+and we have to call the JIT for each of them. Even worse there is the
+possibility of cyclic references, and we would end up in an endless loop.
+
+Thus we need some kind of trampoline function for JIT compilation. Such a
+trampoline first calls the JIT compiler to create native code, and then jumps
+directly into that code. Whenever the JIT needs the address of a function (to
+emit a call instruction) it uses the address of those trampoline functions.
+
+One drawback of this approach is that it requires an additional indirection. We
+always call the trampoline. Inside the trampoline we need to check if the
+method is already compiled or not, and when not compiled we start JIT
+compilation. After that we call the code. This process is quite time consuming
+and shows very bad performance.
+
+The solution is to add some logic to the trampoline function to detect from
+where it is called. It is then possible for the JIT to patch the call
+instruction in the caller, so that it directly calls the JIT compiled code
+next time.
+
+Implementation for x86
+======================
+
+emit-x86.c (arch_create_jit_trampoline): return the JIT trampoline function
+
+emit-x86.c (x86_magic_trampoline): contains the code to detect the caller and
+patch the call instruction.
+
+emit-x86.c (arch_compile_method): JIT compile a method

+
+=head1 Internal design document for the mono_handle_d
+
+This document is designed to hold the design of the mono_handle_d and
+not as an api reference.
+
+=head2 Primary goal and purpose
+
+The mono_handle_d is a process which takes care of the (de)allocation
+of scratch shared memory and handles (of files, threads, mutexes,
+sockets etc. see L<WapiHandleType>) and refcounts of the
+filehandles. It is designed to be run by a user and to be fast, thus
+minimal error checking on input is done and will most likely crash if
+given a faulty package. No effort has been, or should be, made to have
+the daemon talking to machine of different endianness/size of int.
+
+=head2 How to start the daemon
+
+To start the daemon you either run the mono_handle_d executable or try
+to attach to the shared memory segment via L<_wapi_shm_attach> which
+will start a daemon if one does not exist.
+
+=head1 Internal details
+
+The daemon works by opening a socket and listening to clients. These
+clients send packages over the socket complying to L<struct
+WapiHandleRequest>.
+
+=head2 Possible requests
+
+=over
+
+=item WapiHandleRequest_New
+
+Find a handle in the shared memory segment that is free and allocate
+it to the specified type. To destroy use
+L</WapiHandleRequest_Close>. A L<WapiHandleResponse> with
+.type=WapiHandleResponseType_New will be sent back with .u.new.handle
+set to the handle that was allocated. .u.new.type is the type that was
+requested.
+
+=item WapiHandleRequestType_Open
+
+Increase the ref count of an already created handle. A
+L<WapiHandleResponse> with .type=WapiHandleResponseType_Open will be sent
+back with .u.new.handle set to the handle, .u.new.type is set to the
+type of handle this is.
+
+=item WapiHandleRequestType_Close
+
+Decrease the ref count of an already created handle. A
+L<WapiHandleResponse> with .type=WapiHandleResponseType_Close will be
+sent back with .u.close.destroy set to TRUE if ref count for this
+client reached 0.
+
+=item WapiHandleRequestType_Scratch
+
+Allocate a shared memory area of size .u.scratch.length in bytes. A
+L<WapiHandleResponse> with .type=WapiHandleResponseType_Scratch will be
+sent back with .u.scratch.idx set to the index into the shared
+memory's scratch area where to memory begins. (works just like
+malloc(3))
+
+=item WapiHandleRequestType_Scratch
+
+Deallocate a shared memory area, this must have been allocated before
+deallocating. A L<WapiHandleResponse> with
+.type=WapiHandleResponseType_ScratchFree will be sent back (works just
+like free(3))
+
+=back
+
+=head1 Why a daemon
+
+From an email:
+
+Dennis: I just have one question about the daemon... Why does it
+exist? Isn't it better performancewise to just protect the shared area
+with a mutex when allocation a new handle/shared mem segment or
+changing refcnt? It will however be a less resilient to clients that
+crash (the deamon cleans up ref'd handles if socket closes)
+
+Dick: It's precisely because with a mutex the shared memory segment
+can be left in a locked state. Also, it's not so easy to clean up
+shared memory without it (you can't just mark it deleted when creating
+it, because you can't attach any more readers to the same segment
+after that).  I did some minimal performance testing, and I don't
+think the daemon is particularly slow.

+Object and VTable layout
+========================
+
+The first pointer inside an Object points to a MonoVtable structure. Objects
+also contains a MonoThreadsSync structure which is used by the mono Thread
+implementation. 
+ 
+typedef struct {
+	MonoVTable *vtable;
+	MonoThreadsSync synchronisation;
+	
+	/* object specific data goes here */
+} MonoObject;
+
+The MonoVtable contains the vtable, interface offsets and a pointer to static
+class data. Each object/vtable belongs to exactly one AppDomain.
+
+typedef struct {
+	MonoClass  *klass;
+	MonoDomain *domain;  
+        gpointer   *interface_offsets;   
+	/* a pointer to static data */
+        gpointer    data;
+	/* the variable sized vtable is included at the end */
+        gpointer    vtable [0];	
+} MonoVTable;
+
+The MonoClass contains domain independent Class infos.
+
+typedef struct {
+	/* various class infos */
+	MonoClass  *parent;
+	const char *name;
+	const char *name_space;
+	...
+} MonoClass;
+
+
+Calling virtual functions:
+==========================
+
+Each MonoMethod (if virtual) has an associated slot, which is an index into the
+VTable. So we can use the following code to compute the address of a virtual
+function: 
+ 
+method_addr = object->vtable->vtable [method->slot];
+
+
+Calling interface methods:
+==========================
+
+Each interface class is associated with an unique ID. The following code
+computes the address of an interface function:
+
+method_addr = *(object->vtable->interface_offsets [interface_id] + method->slot*4);

+
+More about PInvoke and Internal calls
+=====================================
+
+1.) What is PInvoke
+
+PInvoke stands for Platform Invoke. It is possible to call functions contained
+in native shared libraries, for example you can declare:
+
+	[DllImport("cygwin1.dll", EntryPoint="puts"]
+	public static extern int puts (string name);
+
+If you then call "puts(...)" it invokes the native "puts" functions in
+"cygwin1.dll". It is also possible to specify several marshalling attributes
+for the arguments, for example you can specify that they puts() function expect
+ts the string in Ansi encoding by setting the CharSet attribute field:
+
+	[DllImport("cygwin1.dll", EntryPoint="puts", CharSet=CharSet.Ansi)]
+	public static extern int puts (string name);
+
+2.) What are internal calls
+
+Some class library functions are implemented in C, because it is either not
+possible to implement them in C# or because of performance gains. Internal
+functions are contained in the mono executable itself. Here is an example form
+our array implementation:
+
+	[MethodImplAttribute(MethodImplOptions.InternalCall)]
+	public extern int GetRank ();
+
+If you call this GetRank() function it invokes
+ves_icall_System_Array_GetRank() inside the mono runtime.
+
+If you write your own runtime environment you can add internal calls with
+mono_add_internal_call(). 
+
+
+2.) Runtime considerations
+
+Invoking native (unmanaged) code has several implications:
+
+- We need to handle exceptions inside unmanaged code. The JIT simply saves some
+  informations at each transition from managed to unmanaged code (in a linked
+  list), called Last Managed Frame (LMF). If an exception occurs the runtime
+  first looks if the exception was inside managed code. If not there must be a
+  LMF entry which contains all necessary information to unwind the stack. 
+
+  Creation of those LMF structure clearly involves some overhead, so calling
+  into unmanaged code is not as cheap as it looks like at first glance. Maybe
+  we can introduce a special attribute to avoid the creation of LMF on internal
+  call methods that cant raise exceptions.
+
+- PInvoke has the possibility to convert argument types. For example Strings
+  are marshalled as Char*. So each String argument is translated into a
+  char*. The encoding is specified in the CharSet of the DllImport attribute.
+  
+
+3.) When/how does the runtime call unmanaged PInvoke code
+
+- LDFTN, CALLI, Delegate::Invoke, Delegate::BeginInvoke: We must generate
+  wrapper code when we load the function with LDFTN, so that all arguments are
+  marshalled in the right format. We also need to save/restore the LMF.
+
+- MethodBase::Invoke (runtime invoke): We need to marshal all arguments in
+  they right format and save/restore the LMF
+
+- CALL: We need to marshal all arguments in they right format and save/restore
+  the LMF
+
+The easiest way to implement this is to always create a wrapper function for
+PInvoke calls, which takes care of argument marshalling and LMF save/restore.
+
+4.) When/how does the runtime call unmanaged internal calls
+
+We don't need to convert any arguments, so we need only take care of the LMF
+structure. 
+
+- LDFTN, CALLI, Delegate::Invoke, Delegate::BeginInvoke: We must generate
+  wrapper code when we load the function with LDFTN which saves/restores the
+  LMF.
+
+- MethodBase::Invoke (runtime invoke): We need to save/restore the LMF.
+
+- CALL: We need to save/restore the LMF.
+
+- CALLVIRT (through the vtable): We must generate wrapper code to save/restore
+  the LMF.
+
+Please notice that we can call internal function with CALLVIRT, i.e. we can
+call those function through a VTable. But we cant know in advance if a vtable
+slot contains an internal call or managed code. So again it is best to generate
+a wrapper functions for internal calls in order to save/restore the LMF.
+
+Unfortunately we need to push all arguments 2 times, because we have to save
+the LMF, and the LMF is currently allocated on the stack. So the stack looks
+like:
+
+    --------------------
+    | method arguments |
+    --------------------
+    | LMF              |
+    --------------------
+    | copied arguments |
+    --------------------
+
+AFAIK this is the way ORP works. Another way is to allocate the LMF not on the
+stack, but then we have additional overhead to allocate/free LMF structures
+(and another call to arch_get_lmf_addr).
+
+Maybe it is possible to avoid this addiotional copy for internal calls by
+including the LMF in the C function signature. Lets say we hav a puts()
+function which is a internal call:
+
+ves_icall_puts (MonoString *string);
+
+If we simply modify that to include the LMF we can avoid to copy all arguments:
+
+ves_icall_puts (MonoLMF lmf, MonoString *string);
+
+But this depends somehow on the calling conventions, and I don't know if that
+works on all plattforms? 
+
+
+5.) What is stored in the LMF
+
+- all caller saved registers (since we can trust unmanaged code)
+- the instruction pointer of the last managed instruction
+- a MonoMethod pointer for the unmanaged function
+- the address of the thread local lfm_addr pointer (to avoid another call to
+  arch_get_lmf_addr when restoring LMF)
+
+The LMF is allocated on the stack, so we also know the stack position for
+stack unwinding.

+.TH mcs 1 "6 January 2001"
+.SH NAME 
+mcs \- Mono Compiler Suite.
+.SH SYNOPSIS
+.B mcs 
+[option] [source-files]
+.SH DESCRIPTION
+mcs is the Mono C# compiler, an implementation of the ECMA-334
+language specification.  You can pass one or more options to drive the
+compiler, and a set of source files.  Extra options or arguments can
+be provided in a response file.  Response files are referenced by
+prepending the @ symbol to the response file name.
+.PP
+C# source files must end with a ".cs" extension.  Compilation of C#
+source code requires all the files that make up a library, module or
+executable to be provided on the command line.  There is no support
+for partial compilation.  To achieve the benefits of partial
+compilation, you should compile programs into their own assemblies,
+and later reference them with the "-r" flag.
+.PP
+The Mono C# compiler generates images (.exe files) that contain CIL
+byte code that can be executed by any system that implements a Common
+Language Infrastructure virtual machine such as the Microsoft .NET
+runtime engine on Windows or the Mono runtime engine on Unix systems.
+Executables are not bound to a specific CPU or operating system.
+.PP
+.SH OPTIONS
+.TP
+.I \-\-about
+Displays information about the Mono C# compiler
+.TP
+.I \-\-checked
+Sets the default compilation mode to `checked'.  This makes all
+the math operations checked (the default is unchecked).
+.TP
+.I \-\-define SYMBOL
+Defines a symbol named SYMBOL.  This can be tested in the source code
+by the pre-processor.
+.TP
+.I \-\-debug or \-g
+Generate debugging information.  
+.TP
+.I \-\-fatal 
+This is used for debugging the compiler.  This makes the error emission
+generate an exception that can be caught by a debugger.
+.TP
+.I \-\-stacktrace
+Generates a stack trace at the time the error is reported, useful for
+debugging the compiler.
+.TP
+.I \-L PATH
+Directs the compiler to look for libraries in the specified path.
+Multiple paths can be provided.
+.TP
+.I \-\-nostdlib
+Use this flag if you want to compile the core library.  This makes the
+compiler load its internal types from the assembly being compiled.
+.TP
+.I \-\-noconfig
+Disables the default compiler configuration to be loaded.  The
+compiler by default has references to the system assemblies. 
+.TP
+.I \-\-nowarn XXX
+Makes the compiler ignore warning XXX.
+.TP
+.I \-o FNAME
+Names the output file to be generated.
+.TP
+.I \-\-optimize
+Turns on optimizations in the compiler.  
+.TP
+.I \-\-parse
+Used for benchmarking.  The compiler will only parse its input files.
+.TP
+.I \-\-probe X L
+Probes for the code to generate an error named `X' in line `L'.  This
+is only used by the test suite.
+.TP 
+.I /linkres:RESOURCE
+Links to the given resources
+.TP
+.I \-\-recurse PATTERN
+Does recursive compilation using the specified pattern.  In Unix the
+shell will perform globbing, so you migth want to use it like this:
+.PP
+.nf
+		bash$ mcs --recurse '*.cs' 
+.fi
+.TP
+.I \-\-linkres FILE
+Links FILE as a resource of the resulting assembly.
+.TP
+.I \-\-target KIND
+Used to specify the desired target.  The possible values are: exe,
+winexe, library and module.  
+.TP
+.I \-\-timestamp
+Another debugging flag.  Used to display the times at various points
+in the compilation process.
+.TP
+.I \-\-unsafe
+Enables compilation of unsafe code.
+.TP
+.I \-\-werror
+Treat warnings as errors.
+.TP
+.I \-\-wlevel LEVEL
+Sets the warning level.  0 is the lowest warning level, and 4 is the
+highest.  The default is 2.
+.TP
+.I \-r ASSEMBLY
+Reference the named assembly.  Use this to use classes from the named
+assembly in your program.  The assembly will be loaded from either the
+system directory where all the assemblies live, or from the path
+explicitly given with the -L option.
+.TP
+.I \-v 
+Debugging. Turns on verbose yacc parsing.
+.TP
+.I \-\-
+Use this to stop option parsing, and allow option-looking parameters
+to be passed on the command line.
+.PP
+.SH SPECIAL DEFINES
+The 
+.B TRACE
+and
+.B DEBUG
+defines have a special meaning to the compiler.
+.PP
+By default calls to methods and properties in the
+System.Diagnostics.Trace class are not generated unless the TRACE
+symbol is defined (either through a "#define TRACE") in your source
+code, or by using the
+.I "--define TRACE"
+in the command line.
+.PP
+By default calls to methods and properties in the
+System.Diagnostics.Debug class are not generated unless the DEBUG
+symbol is defined (either through a "#define DEBUG") in your source
+code, or by using the
+.I "--define DEBUG"
+in the command line.
+.PP
+Note that the effect of defining TRACE and DEBUG is a global setting,
+even if they are only defined in a single file.
+.PP
+.SH DEBUGGING SUPPORT
+When use the "--debug" or "-g" flag, MCS will create an assembler file
+FILE-debug.s containing debugging information where FILE is the name of
+the generated assembly. You need to run this file through the assembler
+to get a object file FILE-debug.o.  See mono's "--dwarf-plus" argument
+for details on how to use this file.
+.SH NOTES
+During compilation the MCS compiler defines the __MonoCS__ symbol,
+this can be used by pre-processor instructions to compile Mono C#
+compiler specific code.

+.SH DESCRIPTION
+The \fImono\fP program is a Just in Time compiler for ECMA CLI byte
+codes.  It translates dynamically a CIL stream into native code. 
+.I program.exe
+and optionally passes
+the
+.I arguments
+to it. 
+.SH OPTIONS
+The following options are supported:
+.TP
+.I "--help", "-h"
+Displays usage instructions.
+.I "--share-code"
+This mode makes the LoaderOptimization for Application Domains default
+to sharing code.  This results in slower code, but enables code
+sharing across application domains.  The default is to maximize for
+speed, but disallow JITed code sharing across domains.  See
+System.LoaderOptimization for more information
+.TP
+.I "--config filename"
+Load the specified configuration file instead of the default one(s).
+The default files are /etc/mono/config and ~/.mono/config or the file
+specified in the MONO_CONFIG environment variable, if set.
+.TP
+.I "--noinline"
+Disables the code inliner.
+.SH DEBUGGING OPTIONS
+The following options are used to debug, or perfomance test the JIT
+compiler:
+.TP
+.I "--trace-calls"
+Shows method names as they are invoked.
+.TP
+.I "--dump-asm"
+Displays the generated code as methods are invoked.
+.TP
+.I "--dump-forest"
+Displays the basic blocks and the forest of trees that is 
+created from a stream of CIL opcodes.
+.TP
+.I "--compile name"
+Compiles the method on the given class (namespace.name:methodname) or
+all classes in the given image (@imagename).
+.TP
+.I "--ncompile"
+Compiles the method a number of times.  If no argument is specified,
+the method will be compiled a thousand times.
+.SH DEVELOPMENT OPTIONS
+The following options are used to debug a JITed application.  They're
+only useful when running the JIT in a debugger:
+.TP
+.I "--debug=[format]"
+Writes out debug information in the given format or in the default format.
+See DEBUGGING FORMATS for details.
+.TP
+.I "--debug-args args"
+Comma-separated list of additional arguments for the symbol writer.
+See DEBUGGING FORMATS for details.
+.TP
+.I "--break method"
+Inserts a breakpoint before the method whose name is `method'
+(namespace.class:methodname).
+.TP
+.I "--precompile name"
+Compiles the given class (namespace.name), method (namespace.name:methodname)
+or all classes in the given image (@imagename) before executing the main
+application.
+.TP
+.I "--profile"
+Collect profiling information and dump it at the end of the process.
+.SH DEBUGGING FORMATS
+The following debugging formats are currently supported:
+.TP
+.I "stabs"
+Writes out stabs debug information.
+.TP
+.I "dwarf"
+Writes out dwarf debug information.
+.TP
+.I "dwarf-plus"
+Uses an extended debugging information file which has been generated
+by MCS.  This extended debugging information will allow you to debug
+C# source code rather than IL code.  To use it, just run the JIT in
+your debugger and call "mono_debug_make_symbols" each time the program
+stops.
+.PP
+The "stabs" and "dwarf" formats support the following options:
+.TP
+.I "filename=FILENAME"
+Write debugging information into FILENAME.  This file must be run through
+the assembler to create an object file.
+.TP
+.I "objfile=FILENAME"
+When automatically assembling the symbol file, write the resulting object
+file into FILENAME.
+.TP
+.I "dont_assemble"
+Normally, the symbol file is automatically assembled to an object file
+when you call "mono_debug_make_symbols".  Use this option to disable this
+behaviour.
+.TP
+.I "install_il_files"
+Put the generated *.il files in the same directory than the assembly they
+came from.  The default is to put them into the current working directory.
+.TP
+.I "dont_update_il_files"
+Normally, the *.il files are recreated if their assemblies have changed
+when you call "mono_debug_make_symbols".  Use this option to disable this
+behaviour.
+.TP
+.I "dont_create_il_files"
+Update the *.il files if their assemblies have changed, but only if the
+file already exists.
+.PP
+The "dwarf-plus" format supports the following options:
+.TP
+.I "dont_fallback"
+Don't fallback to normal dwarf2 if the symbol file cannot be found.
+.PP
+.SH FILES
+On Unix assemblies are loaded from the installation lib directory.  If you set
+`prefix' to /usr, the assemblies will be located in /usr/lib.  On
+Windows, the assemblies are loaded from the directory where mono and
+mint live.
+.PP
+/etc/mono/config, ~/.mono/config
+.IP
+Mono runtime configuration file.  See the mono-config(5) manual page
+for more information.

+Basic Installation
+==================
+
+The Mono project has developed mono, an x86-specific CL JIT compiler and
+mint, a portable CLI interpreter. The build process of each of these
+depends on nothing more than a C compiler, glib2 and libgc.
+
+However, to provide a working runtime environment, these programs must
+be supplemented by corlib, a CLR assembly to which they are closely
+tied. This package provides the C# sources for corlib as well as some
+additional assemblies and mcs, the Mono C# compiler.
+
+To build this package, you must already have a C# compiler installed.
+Build instructions for *NIX and Microsoft Windows follow.
+
+Building mcs on *NIX
+====================
+
+mcs provides a set of makefiles which make it easy to build and install
+mcs on *NIX systems like Linux or FreeBSD where mcs is already
+installed.
+
+To build the compiler and class libraries, run:
+
+    make -f makefile.gnu
+
+The libraries will be placed in the directory class/lib/ and the mcs
+compiler executable in mcs/.
+
+To install them, run:
+
+    make -f makefile.gnu install
+
+You can also specify a prefix into which the files will be installed:
+
+    make -f makefile.gnu install prefix=/opt
+
+If you are tracking Mono's development, you may sometimes need to share
+the compiled libraries with others. If you want to produce an easily
+distributable tarball, run:
+
+    make -f makefile.gnu dist
+
+Building mcs on Windows
+=======================
+
+It is also possible to build mcs on Windows using the Microsoft .NET
+framework. This may be convenient if you do not have access to a working
+mcs setup. To build the compiler and class libraries, run:
+
+    make
+
+The libraries will be placed in the directory class/lib/ and the mcs compiler
+executable in mcs/. They can then be copied to /usr/lib and /usr/bin or
+wherever desired on the target system.

+2002-07-05  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs: Added support for types in referenced assemblies.
+
+2002-07-05  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs: Added support for arrays.
+
+	* gdb-csharp-support.patch: Updated.
+
+2002-06-29  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs (DieInheritance): Make this actually work.
+
+2002-06-29  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs, MonoSymbolWriter.cs: Put all TAG_subprogram's into their
+	corresponding struct/class declarations.
+
+2002-06-28  Martin Baulig  <martin@gnome.org>
+
+	* gdb-csharp-support.patch: Updated.
+
+2002-06-28  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs: Use a TAG_string_type when we're using GNU extensions.
+	Make static struct/class fields actually work.  Provide a TAG_typedef for struct's
+	and classes.
+
+2002-05-30  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter (IMonoSymbolWriter): Added custom `Initialize' method.
+
+	* MonoSymbolWriter.cs (Initialize): The ISymbolWriter's `Initialize' method
+	is no longer supported and throws an exception.
+	(Initialize (string, string[])): New custom initialization function.
+
+	* MonoDwarfFileWriter.cs (DwarfFileWriter): Added `string[] args' argument
+	to the constructor to pass command line arguments.
+
+	* gdb-csharp-support.patch: Updated for GDB 5.2.
+
+2002-05-30  Martin Baulig  <martin@gnome.org>
+
+	* MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now get's the
+	AssemblyBuilder's `methods' array as third argument.
+	(OpenMethod): Use this array to get the method builder rather than using an
+	interncall for it.
+	(get_method_builder): Removed this interncall.
+
+2002-05-25  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs: Finished the type rewrite, put back strings and arrays.
+
+2002-05-24  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter.cs (ISourceMethod): Added `FullName' and `Parameters'.
+	(ITypeHandle): New interface.
+
+	* DwarfFileWriter.cs: Largely reorganized the type writing code.  Types are
+	now represented by ITypeHandle objects which are stored in a per-dwarf-writer
+	hash table.  At the moment, all types still need to be in one compile unit due
+	to lacking support in gdb - but this new type code here already supports this.
+
+	* MonoSymbolWriter.cs: Moved all the subclasses to the top-level and made them
+	public, cleaned up the code, put everything into one compile unit.
+	(DefineLocalVariable): Added a version of this function which takes useful args.
+
+2002-05-22  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter.cs (IMonoSymbolWriter): Added `Sources' and `Methods'
+	properties.
+
+	* MonoDwarfFileWriter.cs (WriteSymbolTable): New public method.  Moved the
+	code that writes the "mono_line_numbers" section here from the LineNumberEngine.
+
+2002-05-22  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter.cs (IVariable): Replaced Token with `ISourceMethod Method'.
+
+	* MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now has an additional
+	ModuleBuilder argument.
+	(OpenMethod): Immediately call the `get_method' interncall to get the MethodBase
+	from the token, then store the MethodBase instead of the token.  The token may
+	still change during the metadata library's fixup process.
+	(DoFixups): When the image has been written to disk, call the GetToken () method
+	on all MethodBuilders and all ConstructorBuilders to get the final metadata tokens.
+
+2002-05-22  Martin Baulig  <martin@gnome.org>
+
+	* AssemblerWriterI386.cs: Don't use GNU extensions and produce assembler
+	output which is free of comments and extra whitespaces so that it's suitable
+	for `as -f'.
+
+2002-05-22  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter.cs (ISourceMethod): Replaced `MethodInfo MethodInfo' with
+	`MethodBase MethodBase' and added `Type ReturnType'.  We're now correctly
+	dealing with constructors and not crashing anymore.
+
+2002-05-21  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs: Write a special line number table which can be read
+	in by the metadata library to get line number information in backtraces.
+
+2002-05-06  Martin Baulig  <martin@gnome.org>
+
+	* MonoSymbolWriter.cs (MonoSymbolWriter.Close): Use Assembly.LoadFrom (), not
+	AppDomain.Load () to load the assembly.
+
+2002-04-26  Martin Baulig  <martin@gnome.org>
+
+	* gdb-csharp-support.patch: A patch for GDB (against the latest CVS version)
+	to implement C# support.
+
+	* csharp-lang.c, csharp-lang.h, csharp-mono-lang.c: Copy these into your GDB
+	source directory after applying the patch.
+
+2002-04-26  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs (DieInternalString): Removed.
+
+2002-04-25  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs: Reflect latest MonoString changes.
+
+2002-04-13  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter.cs (ISourceBlock): Added `Blocks' property and `AddBlock'
+	method to support nested blocks.
+
+	* MonoSymbolWriter.cs: Correctly handle nested blocks.
+
+	* MonoDwarfFileWriter.cs (DieMember): Provide info for all fields, not just for
+	public ones; also added DW_AT_accessibility.
+	(DieVariable): Reflected latest debug-symfile.c changes.
+
+2002-04-12  Martin Baulig  <martin@gnome.org>
+
+	* gdb-variable-scopes.patch: A patch for GDB (against the latest CVS version)
+	to implement variable lifetimes.
+
+2002-04-12  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs (DieVariable): Provide info about the variable's
+	lifetime using DW_AT_begin_scope and a new baulig extension DW_AT_end_scope.
+
+2002-03-29  Martin Baulig  <martin@gnome.org>
+
+	* AssemblerWriterI386.cs: Rewrote most of the string output function, do the
+	number->string conversion manually. It's now taking about 15 seconds to write
+	a symbol file for MCS, no longer more than a minute.
+
+	* MonoDwarfFileWriter.cs: Added some profiling code, speeded things up, fixed
+	a few bugs.
+
+2002-03-25  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs (CreateType): Return a `DieType'.
+	(RegisterType): Add the type to the type hash before creating dependency types
+	so we don't get recursion loops.
+	(RegisterPointerType): New func to register a "pointer to type" type.
+	(DieTypeDef, DiePointerType, DieArrayType, DieStringType, DieClassType): New
+	types; added support for strings, arrays and basic support for classes.
+	
+2002-03-24  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter.cs: Killed all methods in this interface, no longer needed.
+
+	* MonoSymbolWriter.cs (MonoSymbolWriter): The constructor now takes a string
+	argument which is the full pathname of the assembly - you must call Close()
+	after the assembly has been written to disk since the symbol writer needs to
+	load the finished assembly to get its metadata.
+
+	* MonoDwarfFileWriter.cs: Added support for enums and structs.
+	
+2002-03-24  Martin Baulig  <martin@gnome.org>
+
+	* MonoDwarfFileWriter.cs: Added support for method parameters.
+
+2002-03-24  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter.cs (IMonoSymbolWriter): Removed my custom OpenMethod(),
+	we're now using the ISymbolWriter's method.
+	(IVariable): Added `byte[] Signature' property.
+
+	* MonoSymbolWriter.cs (SetAssembly): New method. This must be called before
+	Close(); the assembly parameter is the already-written assembly, ie. it must
+	contain the full metadata.
+	(OpenMethod): Only take the token argument and set MethodInfo later in DoFixups.
+	(SetMethodSourceRange): You must call this function to tell the symbol writer
+	in which source file the method is defined.
+	(DefineLocal): Store the signature in the local.
+	(DoFixups): Use two new interncalls to set the SourceMethod's MethodInfo field
+	and the LocalVariable's Type field.
+
+2002-03-23  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter.cs (ISourceBlock): New interface.
+	(ILocalVariable): Renamed this interface to IVariable.
+	(IVariable): Added Line, Type, Token.
+	(ILocalVariable, IMethodParameter): New interfaces, derive from IVariable.
+	(ISourceMethod): Added Blocks. Renamed FirstLine and LastLine to Start and End,
+	changed their type to ISourceLine. Removed CodeSize.
+	(ISourceLine): Renamed Line to Row, added Column. Added OffsetType and Offset.
+
+	* MonoDwarfFileWriter.cs (MonoDwarfFileWriter.DieLexicalBlock): New class.
+	(MonoDwarfFileWriter.DieMethodVariable): New class.
+
+	* MonoSymbolWriter.cs (OpenScope, CloseScope): Implemented.
+	Reflected latest IMonoSymbolWriter interface changes.
+
+2002-03-20  Martin Baulig  <martin@gnome.org>
+
+	* IAssemblerWriter.cs: New interface.
+
+	* AssemblerWriterI386.cs: New class.
+
+	* MonoDwarfFileWriter.cs: Use the IAssemblerWriter interface to make this class
+	platform and assembler independent.
+
+2002-03-20  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter.cs (ISourceMethod): Added FirstLine, LastLine, CodeSize and
+	Token properties.
+
+	* MonoDwarfFileWriter.cs: Implemented line number support.
+
+2002-03-19  Martin Baulig  <martin@gnome.org>
+
+	* IMonoSymbolWriter.cs (ISourceFile, ISourceMethod, ISourceLine, ILocalVariable):
+	New interfaces.
+
+	* IMonoSymbolWriter.cs (OpenMethod): Take a System.Reflection.MethodInfo, not
+	a string.
+
+2002-03-19  Martin Baulig  <martin@gnome.org>
+
+	This is an implementation of the System.Diagnostics.SymbolStore.SymbolWriter
+	interface. It's still work in progress and not yet used anywhere.
+
+	There is some preliminary documentation in the source files and some more
+	docu in the README and README.relocation-table files.
+
+	* IMonoSymbolWriter.cs: New file.
+	* MonoDwarfFileWriter.cs: New file.
+	* MonoSymbolDocumentWriter.cs: New file.
+	* MonoSymbolWriter.cs: New file.
+
+	* README, README.relocation-table: Documentation.

+This is an implementation of the System.Diagnostics.SymbolStore.ISymbolWriter
+interface which writes a dwarf debugging information file.
+
+Unfortunately there are several major problems with this interface and I'm
+unsure how to solve them:
+
+1.) The interface contains a constructor method `Initialize' which has an
+    'IntPtr' emitter argument which seems to be a pointer to the actual
+    symbol writer which resides in a proprietary, undocumented DLL (I spent
+    almost 3 hours browsing the ".NET Framework SDK Documentation" and
+    msdn.microsoft.com - without success.
+
+    A short test showed me that mscorlib doesn't like passing zero, this
+    won't give you the system's default implementation.
+
+    To solve this problem, I created a derived interface IMonoSymbolWriter
+    which contains an additional constructor which only takes the name of
+    the symbol file as argument.
+
+        void Initialize (string filename);
+
+2.) You seem to get an instance of a class implementing this interface by
+    creating a new instance of System.Reflection.Emit.ModuleBuilder (with the
+    `bool createSymbolFile' argument) and then calling GetSymWriter() on
+    the returned object.
+
+    So far so good, but how does this method find out which symbol writer
+    to use ?
+
+3.) According to the documentation, some of the methods of
+    System.Reflection.Emit.ILGenerator and System.Reflection.Emit.LocalBuilder
+    seem to use the symbol writer to emit symbol debugging information.
+
+    But again, how do these objects get the symbol writer ?
+
+Currently, there are two ways to use this assembly:
+
+a.) Fix the problems outlined above and dynamically load this assembly
+    (Mono.CSharp.Debugger.dll) when a new symbol writer is created.
+
+b.) Reference this assembly in your application and manually create the
+    symbol writer using the constructor.

+This is an implementation of the System.Diagnostics.SymbolStore.ISymbolWriter
+interface which writes a symbol file in the dwarf format.
+
+The output is an assembler input file containing dwarf data with an
+additional ELF section called ".mono_reloc_table". This section is
+read by the JIT engine to map IL offsets and such to machine
+addresses.
+
+The mono relocation table contains of
+
+1. A 2-byte unsigned integer containing a version number, currently 2.
+
+2. A 1-byte unsigned integer containing a flag specifying whether the
+   object file containing this section has already been relocated.
+
+   The symbol writer sets this flag to zero, you must change it to 1
+   if you write the relocated file back to disk.
+
+3. A 4-byte unsigned integer containing the total size of the
+   relocation table, but not including the size field itself.
+
+4. One or more relocation entries.
+
+Each entry in the relocation table has the following form:
+
+1. A 1-byte unsigned integer specifying the type of this entry.
+
+2. A 4-byte unsigned integer containing the size of this entry, but
+   not including the size field itself.
+
+3. A 1-byte unsigned integer specifying the ELF section of this entry.
+
+4. A 4-byte unsigned offset from the beginning of the ELF section to
+   the location which needs to be relocated. This is called the target.
+
+5. Optional additional data depending on the type of the entry.
+
+The following entry types are currently defined:
+
+a) TARGET_ADDRESS_SIZE - 0x01
+
+   The target is a 1-byte unsigned integer containing the size in
+   bytes of an address on the target machine.
+
+b) IL_OFFSET - 0x02
+
+   The target is an integer of appropriate size to hold an address on
+   the target machine (the assembler ensures that the object has the
+   correct size) and contains an IL offset from the beginning of the
+   current method which needs to be replaced with the corresponding
+   machine address.
+
+   This entry has a 4-byte unsigned integer argument containing the
+   metadata token of the current method and a 4-byte unsigned integer
+   argument containing the IL offset.
+
+c) METHOD_START_ADDRESS - 0x03
+d) METHOD_END_ADDRESS - 0x04
+
+   The target is an integer of appropriate size to hold an address on
+   the target machine (the assembler ensures that the object has the
+   correct size).
+
+   This entry has a 4-byte unsigned integer argument containing the
+   metadata token of the current method.
+
+To use the generated object file, the JIT must:
+
+* Check whether the file contains a ".mono_reloc_table" section.
+  If not, the file cannot be used (you need to change the address size
+  field in each compilation unit header).
+
+* Check whether the flag field of the relocation table (the 3rd byte
+  of the relocation table) is zero. If it is 1, the file has already
+  been relocated. In this case, it's best to reject the file.
+
+* Set the flag field to 1.
+
+* Process all relocation entries.
+
+* Write the modified file back to disk.
+
+To do the relocation, the JIT can assume that:
+
+1.) All the relevant ELF sections are physically contiguous
+    (a requirement from the DWARF 2 specification).
+
+2.) All relocation targets holding addresses are suitable of holding
+    an address on the target machine.
+
+    This means that you can do something like
+
+	* (void **) ptr = map_to_machine (* (void **) ptr)
+
+3.) There are no other changes needed in the object file - so you can
+    just write it back to disk once you're done with the relocation.

+
+	* Mono.Data.MySql.build: modified
+	need to copy Mono.Data.MySql.dll to mcs/class/System.Data/Test
+	so the SqlSharpCli test program can use MySql too
+
+2002-05-30  Daniel Morgan <danmorg@sc.rr.com>
+	
+	* Test/TestMySqlInsert.cs: added test
+	to do an SQL INSERT to insert a row into table.
+	Works on cygwin compiled using mcs and mono and
+	runs on mint, but it fails running on mono.
+	
+	* Mono.Data.MySql/MySqlCommand.cs
+	* Mono.Data.MySql/TODOAttribute.cs
+	* Mono.Data.MySql/MySqlConnection.cs: added
+	
+	* list: added
+	so can build with mcs/mono on linux
+	I only tested it on Cygwin though.
+	To work on linux, the library name in the pinvokes
+	in MySql.cs will need to be changed.
+	
+	* Mono.Data.MySql.build: modified
+	exclude files from build.  also copy Mono.Data.MySql.dll
+	to Mono.Data.MySql so you can build and run Test.cs
+	
+	* Mono.Data.MySql/MySql.cs: modified
+	tweaks to compile under mcs/mono and run under mint or mono.
+	Runs under mint, but not mono. Had to comment out 
+	mysql_thread_begin/mysql_thread_end functions because they refused
+	to load in mono.  Until this is fixed, a memory leak will occur.
+	Can not retrieve field data from MySQL because the PtrToStructure()
+	needs to be implemented in System.Runtime.InteropServices.Marshal class.
+	However, this will be very complicated to do.  So, we connect to
+	MySQL and execute SQL Commands,	but we can not do Queries yet.
+		
+	* Mono.Data.MySql/Test.cs: modified
+	tweaks to test C# bindings with compiling mcs/mono and
+	running on mint and mono.  Runs on mint, but not mono.
+
+2002-05-28  Daniel Morgan <danmorg@sc.rr.com>
+
+	* Mono.Data.MySql
+	* Mono.Data.MySql/Mono.Data.MySql: add directories
+	for the Mono.Data.MySql assembly and namespace.  This
+	will contain the MySql .NET Data Provider which will use
+	C# bindings to libMySQL
+	
+	* Mono.Data.MySql/Test.cs: added file to
+	test the C# bindings to MySQL
+	
+	* Mono.Data.MySql/MySql.cs
+	* Mono.Data.MySql/Field.cs: added files
+	for the beginnings of C# bindings to MySQL
+	
+	* Mono.Data.MySql/makefile: added file
+	to build the MySQL C# bindings on csc/Microsoft.NET
+	
+	These C# bindings to the MySQL libMySQL.dll were created by
+	Brad Merrill <zbrad@cybercom.net> 
+	and can be downloaded from
+	http://www.cybercom.net/~zbrad/DotNet/MySql/
+	and put into the Mono Class Library under the X11/MIT License
+	with Brad Merril's permission.

+//       This is so we can retrieve Field data from MySQL.
+//
+// TODO: more functions in the MySQL C Client API
+//       (libmysqlclient.so on linux and libmySQL.dll on cygwin)
+//       need to be added here as C# pinvoke methods.
+//       Other data structures may need to be added as well.

+The class libraries are grouped together in the assemblies they belong.
+
+Each directory here represents an assembly, and inside each directory we
+divide the code based on the namespace they implement.
+
+In addition, each assembly directory contains a Test directory that holds the
+NUnit tests for that assembly. 
+
+The nant build file for an assembly creates two versions of the dll for that
+assembly. One version is a "full" dll.  The full dll contains (almost) all 
+of the classes, regardless of how complete the classes are. The name of this
+dll is the normal name you would expect, like "corlib.dll" or "System.dll".
+These full dll's are created in the /mcs/class/lib directory.
+
+The other dll which is built is a "restricted" dll.  The restricted dll
+omits incomplete classes that would prevent the NUnit testrunner from actually
+running the tests. These restricted dll's are created in the Test directory
+of their respective assembly and named with a "_res" suffix.  So, for example,
+the NUnit-testable dll for corlib is /mcs/class/corlib/Test/corlib_res.dll.
+
+The final dll which is built is the one which houses the actual NUnit tests.
+This dll is built from all of the classes in the Test directory and below, and
+is named with a "_test" suffix. So, for example, the NUnit tests for corlib
+are in /mcs/class/corlib/Test/corlib_test.dll. This dll is also linked with 
+the restricted dll found in the same directory.
+
+
+* Missing implementation bits
+
+	If you implement a class and you are missing implementation bits,
+	please use the attribute [MonoTODO].  This attribute can be used
+	to programatically generate our status web pages:
+
+	[MonoTODO]
+	int MyFunction ()
+	{
+		throw new NotImplementedException ();
+	}
+
+* Tagging buggy code
+
+	If there is a bug in your implementation tag the problem by using
+	the word "FIXME" in the code, together with a description of the 
+	problem.
+
+	Do not use XXX or obscure descriptions, because otherwise people
+	will not be able to understand what you mean.
+
+* Tagging Problematic specs.
+
+	If the documentation and the Microsoft implementation do
+	differ (you wrote a test case to prove this), I suggest that you edit
+	the file `mcs/class/doc/API-notes' so we can keep track of these problems
+	and submit our comments to ECMA or Microsoft and seek clarification.
+
+	Sometimes the documentation might be buggy, and sometimes the implementation
+	might be buggy.  Lets try to identify and pinpoint which one
+	is the correct one.
+
+	Sometimes the specification will be lame (consider Version.ToString (fieldCount)
+	where there is no way of knowing how many fields are available, making the API
+	not only stupid, but leading to unreliable code).
+
+	In those cases, use the keyword "LAMESPEC".
+	
+
+* Coding considerations and style.
+
+	In order to keep the code consistent, please use the following
+	conventions.  From here on `good' and `bad' are used to attribute
+	things that would make the coding style match, or not match.  It is not
+	a judgement call on your coding abilities, but more of a style and 
+	look call.  Please try to follow these guidelines to ensure prettiness.
+
+	Use 8 space tabs for writing your code (hopefully we can keep
+	this consistent).  If you are modifying someone else's code, try
+	to keep the coding style similar.
+
+	Since we are using 8-space tabs, you might want to consider the Linus
+	Torvals trick to reduce code nesting.  Many times in a loop, you will
+	find yourself doing a test, and if the test is true, you will nest.
+	Many times this can be changed.  Example:
+
+
+		for (i = 0; i < 10; i++) {
+			if (something (i)) {
+				do_more ();
+			}
+		}
+
+	This take precious space, instead write it like this:
+
+		for (i = 0; i < 10; i++) {
+			if (!something (i))
+				continue;
+			do_more ();
+		}
+
+	A few guidelines:
+
+		* Use a space before an opening parenthesis when calling
+		  functions, or indexing, like this:
+
+			method (a);
+			b [10];
+
+		* Do not put a space after the opening parenthesis and the 
+		  closing one, ie:
+
+			good: method (a);	array [10];
+
+			bad:  method ( a );	array[ 10 ];
+
+		* Inside a code block, put the opening brace on the same line
+	  	  as the statement:
+
+			good:
+				if (a) {
+					code ();
+					code ();
+				}
+
+			bad:
+				if (a) 
+				{
+					code ();
+					code ();
+				}
+
+		* Avoid using unecessary open/close braces, vertical space
+		  is usually limited:
+
+			good:
+				if (a)
+					code ();
+
+			bad:
+				if (a) {
+					code ();
+				}
+
+		* When defining a method, use the C style for brace placement, 
+		  that means, use a new line for the brace, like this:
+
+			good:
+				void Method ()
+				{
+				}
+
+			bad:
+				void Method () {
+				}
+
+		* Properties and indexers are an exception, keep the
+		  brace on the same line as the property declaration.
+		  Rationale: this makes it visually
+		  simple to distinguish them.
+
+			good:
+				int Property {
+					get {
+						return value;
+					}
+				}
+
+			bad:
+				int Property 
+				{
+					get {
+						return value;
+					}
+				}
+
+		  Notice how the accessor "get" also keeps its brace on the same
+		  line.
+
+		  For very small properties, you can compress things:
+
+			ok:
+				int Property {
+					get { return value; }
+					set { x = value; }
+				}
+
+		* Use white space in expressions liberally, except in the presence
+		  of parenthesis:
+
+			good:
+
+				if (a + 5 > method (blah () + 4))
+
+			bad:
+				if (a+5>method(blah()+4))
+
+		* For any new files, please use a descriptive introduction, like
+		  this:
+
+			//
+			// System.Comment.cs: Handles comments in System files.
+			//
+			// Author:
+			//   Juan Perez (juan@address.com)
+			//
+			// (C) 2002 Address, Inc (http://www.address.com)
+			//
+
+		* If you are modyfing someone else's code, and your contribution
+		  is significant, please add yourself to the Authors list.
+
+		* Switch statements have the case at the same indentation as the
+		  switch:
+
+			switch (x) {
+			case 'a':
+				...
+			case 'b':
+				...
+			}
+
+		* Argument names should use the camel casing for
+		  identifiers, like this:
+
+		 	good:
+				void Method (string myArgument)
+
+			bad:
+				void Method (string lpstrArgument)
+				void Method (string my_string)
+
+	Here are a couple of examples:
+
+class X : Y {
+
+	bool Method (int argument_1, int argument_2)
+	{
+		if (argument_1 == argument_2)
+			throw new Exception (Locale.GetText ("They are equal!");
+
+		if (argument_1 < argument_2) {
+			if (argument_1 * 3 > 4)
+				return true;
+			else
+				return false;
+		}
+
+		//
+		// This sample helps keep your sanity while using 8-spaces for tabs
+		// 
+		VeryLongIdentifierWhichTakesManyArguments (
+			Argument1, Argument2, Argument3,
+			NestedCallHere (
+				MoreNested));
+	}
+
+	bool MyProperty {
+		get {
+			return x;
+		}
+
+		set {
+			x = value;
+		}
+	}
+
+	void AnotherMethod () 
+	{
+		if ((a + 5) != 4) {
+		}
+
+		while (blah) {
+			if (a)
+				continue;
+			b++;
+		}
+	}
+}
+

+	- ExecuteNonQuery(), ExecuteScalar(), and ExecuteReader()
+	should handle the results from SQL Commands and Queries.
+	- Internal class SqlResult should not create schema Table
+	for the result from a SQL Command.  Also, set the RecordsRetrieved
+	property for SqlDataReader.
+	- Closing the SqlDataReader should Close() the SqlConnection for
+	a CommandBehavior.CloseConnection.
+	- Set defaults for SqlResult
+	
+	* System.Data.SqlClient/SqlConnection.cs: modified - 
+	when SqlDataReader is Close()
+	should Close() the SqlConnection for
+	a CommandBehavior.CloseConnection.  Changed internal Property
+	from OpenReader get/set to IsReaderOpen get and created
+	internal methods OpenReader()/CloseReader() for SqlCommand to call.
+	SqlConnection needs to be prevented from doing while SqlDataReader
+	is being used.
+	
+	* System.Data.SqlClient/SqlDataReader.cs: modified -
+	call SqlCommand's OpenReader() internal method.  get
+	RecordsRetrieved from SqlResult.  set/reset default
+	values for SqlDataReader.
+	
+	* Test/PostgresTest.cs
+	* Test/TestExecuteScalar.cs
+	* Test/TestSqlDataReader.cs: modified
+	for the Execute...() methods in SqlCommand
+	to test SQL Queries and Commands
+	
+	* Test/System.Data_test.build: modified
+	exclude new file Test/SqlSharpCli.cs from 
+	test build
+	
+2002-05-24  Tim Coleman <tim@timcoleman.com>
+	* System.Data.Common/DbDataAdapter.cs: remove IDbCommands, except
+	for get accessors.  These should be implemented in derived classes.  See
+	SqlDataAdapter for clues.
+	* System.Data.SqlClient/SqlDataAdapter.cs: implement IDbDataAdapter
+	* System.Data.Common/DataAdapter.cs:
+	* System.Data.Common/DataTableMappingCollection.cs:
+	* System.Data.Common/DataTableMapping.cs:
+	* System.Data.Common/DataColumnMappingCollection.cs:
+	* System.Data.Common/DataColumnMapping.cs:
+	Properly (I hope!) implement all of the appropriate interfaces
+	for these classes.  
+
+
+2002-05-23  Tim Coleman <tim@timcoleman.com>
+	* System.Data.SqlClient/SqlCommand.cs: include
+	the BaseColumnName in the schema table.  Was missed before.
+	* System.Data.Common/DbDataAdapter.cs: Use DataTable
+	mappings so that the DataSet and DataTable are more closely tied.
+	Get schema information from the DataTable using GetSchemaTable ()
+	Various other little fixes
+	* System.Data.Common/DataColumnMappingCollection.cs:
+	* System.Data.Common/DataTableMapping.cs:
+	* System.Data.Common/DataTableMappingCollection.cs: Some
+	implementation, enough to be used by DbDataAdapter.
+
+2002-05-23  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.SqlClient/SqlCommand.cs: set
+	the "ProviderType" to the PostgreSQL type oid
+	
+	* System.Data.SqlClient/SqlDataReader.cs: fix
+	for various properties and methods that 
+	return meta data: Item indexers this[name] and this[index],
+	GetFieldType, GetName, and GetOrdinal.  SqlDataAdapter
+	should work again.
+
+2002-05-22  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data/DataRow.cs: change suggested
+	by tim: in Item indexer, do an EndEdit()
+	
+	* System.Data.SqlClient/SqlCommand.cs: more
+	fixes to SqlResult.  After setting each item in
+	the DataRow, do an AcceptChanges() to commit
+	the changes in the DataRow.  For DataType, use a Type
+	of System.String since System.Type nor System.Object
+	seems to work.
+	
+	* Test/TestSqlDataReader.cs
+	* Test/PostgresTest.cs: updated to to be on
+	the way schema table is suppose to work
+
+2002-05-22  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.SqlClient/SqlCommand.cs: more work on 
+	building the schema table
+
+2002-05-22  Tim Coleman <tim@timcoleman.com>
+	* System.Data.SqlClient/SqlCommand.cs: preliminary work
+	on getting the schema table correctly built.
+
+2002-05-21  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.SqlClient/ParmUtil.cs: added file - to
+	provide utility for conversion of input parameters
+	
+	* System.Data.SqlClient/PostgresTypes.cs: added file - 
+	moved the PostgreHelper class to here.  May eventually
+	move the internal class PostgresTypes that's inside the 
+	SqlConnection to here as well.  
+	Handling of PostgreSQL <-> .NET types need to be though
+	out more. Also, the PostgreHelper has a method to convert
+	from .NET types to a string which can be put into used in
+	an SQL statement to execute against a PostgreSQL database.
+	This is the beginnings of parameters support.  It currently
+	only supports input parameters.  Still need to do output,
+	input/output, and return parameters.
+	
+	* Test/TestSqlParameters.cs: new test to test the input
+	parameters in System.Data.SqlClient against a 
+	PostgreSQL db.
+	
+	* System.Data.SqlClient/PostgresLibrary.cs: moved 
+	PostgresHelper class to file PostgresTypes.cs.  Also 
+	moved struct PostgresType there too.
+	
+	* System.Data.SqlClient/SqlCommand.cs: added input 
+	parameters support
+	
+	* System.Data.SqlClient/SqlParameter.cs: got 
+	SqlParameter to work
+	
+	* System.Data.SqlClient/SqlParameterCollection.cs: got 
+	SqlParameterCollection to work
+	
+	* Test/System.Data_test.build: added files to exclude 
+	from test build
+	
+	* System.Data.SqlClient/SqlConnection.cs: release resources
+	no longer used
+
+2002-05-18  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Xml: added directory for classes with namespace
+	System.Xml to go into the System.Data.dll assembly
+	
+	* System.Xml/XmlDataDocument: added file
+	for stubbed concrete class XmlDataDocument which 
+	inherits from XmlDocument.  Its purpose is to provide
+	a W3C XML DOM Document for relational data and interacting
+	with a DataSet
+
+2002-05-18  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.SqlClient/SqlCommand.cs: handle CommandTypes
+	Text, TableDirect, and StoredProcedure
+	
+	* Test/PostgresTest.cs: changed call to version() 
+	stored procedure to use the CommandType of StoredProcedure
+	
+	* Test/TestSqlDataReader.cs: test all the CommandTypes
+
+2002-05-18  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.build: took out all excluded
+	files except the ones in the Test directory
+	because all files compile now.  It does not
+	mean they all work or have implementations
+	though.
+	
+	* System.Data/DataRelationCollection.cs
+	* System.Data/DataTableRelationCollection.cs
+	* System.Data/InternalDataCollectionBase.cs
+	* System.Data.Common/DbDataPermission.cs
+	* System.Data.SqlClient/SqlInfoMessageEventArgs.cs
+	* System.Data.SqlClient/SqlClientPermission.cs
+	* System.Data.SqlClient/SqlClientPermissionAttribute.cs: changes
+	to get all System.Data* files to compile.
+	
+	* System.Data.SqlClient/SqlCommand.cs: started coding
+	to prevent SqlConnection and SqlCommand from doing
+	anyting while fetching data using SqlDataReader.  Also,
+	started coding to undo this prevention once the 
+	SqlDataReader is closed.
+	
+	* System.Data.SqlClient/SqlConnection.cs: get database server
+	version.  Started coding to prevent connection from 
+	doing anything while fetching data and undo once the reader 
+	is closed.  Include events SqlInfoMessage and StateChange.
+	
+	* System.Data.SqlClient/SqlDataReader.cs: start coding to
+	prevent connection and command from doing anything while
+	fetching data, and undo when closed.
+	
+	* Test/PostgresTest.cs: added test to get ServerVersion
+	property from SqlConnection
+
+2002-05-18  Tim Coleman <tim@timcoleman.com>
+	* System.Data/DataRow.cs: More implementation,
+	as well as boundary checks and small semantic
+	repairs
+
+2002-05-18  Tim Coleman <tim@timcoleman.com>
+	* System.Data/DataRow.cs: Try to reduce memory
+	usage by only creating the original and proposed
+	arrays as required in BeginEdit, and then destroying
+	proposed during EndEdit, and original during AcceptChanges.
+	* System.Data.Common/DbDataAdapter.cs: Make the
+	startRecord and maxRecords parameters work correctly.
+
+2002-05-18  Tim Coleman <tim@timcoleman.com>
+	* System.Data/DataRow.cs: Move the null check in
+	ItemArray set to above the Invalid Cast check, so
+	that we don't get null reference exceptions.
+
+2002-05-17  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.SqlClient/PostgresLibrary.cs: handle
+	data value from database being NULL
+	
+	* System.Data.SqlClient/SqlCommand.cs: for ExecuteReader, 
+	allow multiple result sets.  Added new internal class
+	SqlResult to pass result set data from SqlCommand
+	to SqlDataReader.
+	
+	* System.Data.SqlClient/SqlDataReader.cs: allow
+	multiple result sets.
+	
+	* System.Data.SqlClient/SqlConnection.cs: moved 
+	things around.  Implement IDisposable.
+	
+	* Test/TestSqlDataReader.cs: test for execution
+	of multiple result sets and display the results
+	of these multiple results sets
+	
+	* Test/TestSqlDataAdapter.cs: tweaks
+
+2002-05-17  Tim Coleman <tim@timcoleman.com>
+	* System.Data.Common/DbDataAdapter.cs:
+		- More implementation of Fill methods
+		- Get rid of isDirty flag, because we can just check
+			if the table exists
+		- Do *not* remove DataTables before Filling them
+		- Implicitly open the connection before doing a Fill
+			if it does not exist.
+	* System.Data.SqlClient/SqlDataAdapter.cs:
+		- Minor fixup
+	* System.Data/DataTableCollection.cs:
+		- Add DataSet to internal, undocumented constructor
+		- When a table is created, set its DataSet property
+		- Default table name for creation is "Table1" (see .NET)
+		- Inherit the ArrayList list from InternalDataCollecitonBase
+			and maintain a hashtable between table names and
+			DataTables
+	* System.Data/DataTable.cs:
+		- Add internal dataSet field.  This is used by 
+			DataTableCollection when the DataTable is constructed.
+	* System.Data/DataSet.cs:
+		- Pass a reference to the DataSet when constructing the
+			DataTableCollection.
+
+2002-05-16  Tim Coleman <tim@timcoleman.com>
+        * System.Data.Common/DbDataAdapter.cs:
+                Use table.Rows.Add (itemArray) instead of
+                table.Rows.Add (thisRow) to provide better
+                abstraction.
+        * System.Data/DataRowCollection.cs:
+                Some implementation of this class.
+        * System.Data/InternalDataCollectionBase.cs:
+                Some implementation.  Most notably, this now
+                has an enumerator so we can use foreach (DataRow row in table.Rows)
+                in the test classes.
+        * System.Data/DataTable.cs:
+                Since DataRowCollection now accepts a DataTable in
+                its internal constructor, we must pass one in.
+
+2002-05-16  Daniel Morgan <danmorg@sc.rr.com>
+
+	* Test/TestSqlDataAdapter.cs: added new test 
+	for SqlDataAdapter, DataSet, DataTableCollection, DataTable, 
+	DataRowCollection, and DataRow.  It tests retrieving data
+	based on a SQL SELECT query.  This test is based on Tim Coleman's
+	test he sent to me.
+
+2002-05-16  Tim Coleman <tim@timcoleman.com>
+	* System.Data.Common/DbDataAdapter.cs:
+		Use table.Rows.Add (thisRow) instead of 
+		table.ImportRow (thisRow)
+	* System.Data/DataRowCollection.cs:
+		Construct the ArrayList before using it
+
+2002-05-16  Tim Coleman <tim@timcoleman.com>
+	* System.Data/DataTable.cs:
+		Construct the DataRowCollection in the DataTable
+		constructor.  Otherwise, it's a null reference.
+
+2002-05-16  Tim Coleman <tim@timcoleman.com>
+	* System.Data.SqlClient/SqlDataReader.cs:
+		Modify GetValues to use Array.Copy() to copy
+		the results from fields to values, rather than
+		an assignment, which results in loss of data.
+
+2002-05-16  Tim Coleman <tim@timcoleman.com>
+	* System.Data/DataRow.cs:
+		More implementation and documentation.  It should
+		work more like expected, although there is no way
+		to demonstrate this well yet.  DataTable requires
+		more work.
+
+2002-05-15  Tim Coleman <tim@timcoleman.com>
+        * System.Data/DataRow.cs:
+	                Minor tweaks as I determine exactly how to
+			                implement this class.
+
+
+2002-05-14  Duncan Mak  <duncan@ximian.com>
+
+	* System.Data/DataTable.cs (NewRow): Added missing paren to fix build.
+
+2002-05-14  Tim Coleman
+	* System.Data/DataRow.cs:
+	* System.Data/DataRowBuilder.cs:
+	* System.Data/DataTable.cs:
+		More implementation of these classes.  DataRow
+		can now (possibly) do some useful things.
+		Still not sure what DataRowBuilder is all about,
+		other than passing a DataTable in.
+
+2002-05-14  Tim Coleman
+	* System.Data/DataRowBuilder.cs:
+		Add stubb for this internal class.
+
+2002-05-13  Tim Coleman
+	* System.Data.Common/DbDataAdapter.cs:
+		The maxRecords check was not correct.
+
+2002-05-13  Tim Coleman
+	* System.Data/DataTableCollection.cs:
+		Fix an issue when adding a DataTable and size == 0.
+		Now explicitly checks if size > 0 before doing Array.Copy ()
+	* System.Data.Common/DbDataAdapter.cs:
+		Move closer to a working implementation.
+		Make the IDbCommand fields protected so that they can
+		be inherited.
+	* System.Data.SqlClient/SqlDataAdapter.cs:
+		This should inherit the IDbCommands instead of having its
+		own.  An explicit cast is used to force conversion between
+		IDbCommand and SqlCommand
+
+2002-05-13  Tim Coleman
+	* System.Data.Common/DataTableMappingCollection.cs:
+		Some implementation to allow progress with DbDataAdapter
+
+2002-05-13  Tim Coleman
+	* System.Data.Common/DbDataAdapter.cs:
+		Modify to not break compile.
+
+2002-05-13  Tim Coleman
+	* System.Data.build:
+		include SqlDataAdapter, SqlRowUpdatedEventArgs,
+		SqlRowUpdatingEventArgs, SqlRowUpdatedEventHandler,
+		SqlRowUpdatingEventHandler in the build.
+
+2002-05-13  Tim Coleman
+	* System.Data.Common/DbDataAdapter.cs:
+		More implementation.
+	* System.Data.Common/DataAdapter.cs:
+		Correction of some of the stubbing, as well as a
+		little bit more implementation
+
+2002-05-11  Tim Coleman
+	* System.Data.SqlClient/SqlDataAdapter.cs:
+	* System.Data.Common/DbDataAdapter.cs:
+		Moved methods that weren't supposed to 
+		be in SqlDataAdapter out.  They should be implemented
+		in DbDataAdapter.
+	
+
+2002-05-11  Tim Coleman
+        * System.Data.SqlClient/SqlDataAdapter.cs:
+                some implementation of this class.  Note
+                that none of the functionality has been
+                tested yet, but I felt it should be checked
+                in at this point as it compiles.
+        * System.Data.SqlClient/SqlRowUpdatingEventArgs.cs:
+        * System.Data.SqlClient/SqlRowUpdatedEventArgs.cs:
+                Modified so that they will compile properly.
+                Needed to include SqlDataAdapter in the build.
+
+2002-05-11  Rodrigo Moya <rodrigo@ximian.com>
+
+	* System.Data/DataTable.cs (Clear): implemented.
+	(DataTable): removed repeated code in constructors, and call the
+	basic constructor from the others.
+
+	* System.Data/DataColumn.cs: some tweaks.
+
+	* System.Data/DataRow.cs (RowState): implemented.
+	(CancelEdit): set rowState property back to Unchanged.
+	(RejectChanges): call CancelEdit.
+	(Delete): set rowState to Deleted.
+
+2002-05-11  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.build: added copy of System.Data.dll to Test directory
+	for easy testing.  Also, added clean for it too.
+	
+	* System.Data.SqlClient/PostgresLibrary.cs: changed setting of boolean
+	from PostgreSQL data type to .NET type.
+	
+	* System.Data.SqlClient/SqlDataReader.cs: beginnings
+	handling of a NULL value from the database
+	
+	* Test/PostgresTest.cs: added tests for NULL values retrieved
+	from the database
+	
+	* Test/ReadPostgresData.cs
+	* Test/TestExecuteScalar.cs
+	* Test/TestSqlDataReader.cs
+	* Test/TestSqlException.cs
+	* Test/TestSqlIsolationLevel.cs: updated tests to use databas user
+	"postgres".  These tests may eventually be removed since they
+	are not flexible.
+
+2002-05-10  Rodrigo Moya <rodrigo@ximian.com>
+
+	* System.Data.build: removed reference to non-existant
+	TestDataColumn.cs file.
+
+	* System.Data/DataSet.cs: added some implementation.
+
+2002-05-09  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.SqlClient/PostgresLibrary.cs: got
+	PostgreSQL data types time, date, timestamp (DateTime like)
+	mapped to .NET System.DateTime working based 
+	on ISO DateTime formatting "YYYY-MM-DD hh:mi:ss.ms"
+	Also mapped pg type boolean to .net Boolean
+	
+	* SqlClient/SqlConnection.cs: run SQL command to set
+	Date style to ISO
+	
+	* Test/PostgresTest.cs: added test for an UPDATE SQL command,
+	added tests for aggregates min(), max(), sum(), count().  could
+	not get avg() to work due to some formatting error; someone claimed
+	that it was my locale settings.  added tests for SELECT of columns
+	of type boolean, float, double, date, time, and timestamp.  They
+	have not been fully tested, but its a start.
+
+2002-05-09  Tim Coleman <tim@timcoleman.com>
+	* System.Data.SqlTypes/SqlDecimal.cs: Implementations of 
+	addition, subtraction, and multiplication for the
+	SqlDecimal type, as well as modification of some other
+	operations.  More to come on this one.
+
+2002-05-08  Rodrigo Moya <rodrigo@ximian.com>
+
+	* Test/System.Data_test.build: excluded TestDataColumn, which
+	should be replaced with a nunit test.
+
+	* Test/TestDataColumn.cs: added basic test for DataColumn.cs.
+
+2002-05-07  Tim Coleman <tim@timcoleman.com>

+
+2002-05-07  Tim Coleman <tim@timcoleman.com>
+	* SqlString.cs:
+		Fix a symantic error I made in SqlString
+		Equals where I copied and pasted wrongly
+
+2002-05-07  Tim Coleman <tim@timcoleman.com>
+	* INullable.cs:

+	* SqlSingle.cs:
+	* SqlString.cs:
+		Implement CompareTo, Equals, and String conversions 
+		for many types
+
+2002-05-05  Daniel Morgan <danmorg@sc.rr.com>
+
+	* Test/PostgresTest.cs: modified to run completely.  There
+	are many TODOs in System.Data, so not all data types are
+	included in the SELECT SQL query.  Also, I made it to where
+	it would connect 
+	using "host=localhost;dbname=test;user=postgres"
+	instead of my userid and password.  When more types are included,
+	update this test.
+
+2002-05-05  Daniel Morgan <danmorg@sc.rr.com>
+
+	* Test/PostgresTest.cs: added - ported
+	libgda postgres-test.c originally by 
+	Gonzalo Paniagua Javier <gonzalo@gnome-db.org>
+	to C#.
+
+2002-05-05  Tim Coleman <tim@timcoleman.com>

+	* System.Data.SqlTypes/SqlMoney.cs:
+	* System.Data.SqlTypes/SqlSingle.cs:
+	* System.Data.SqlTypes/SqlString.cs:
+		More implementation, and code clean-up for consistency.
+		Also, I had implemented many conversions as explicit
+		that should have been implicit.  This should remove
+		many of the red X's and green pluses from the 
+		System.Data.SqlTypes namespace.
+
+2002-05-05  Miguel de Icaza  <miguel@ximian.com>
+
+	* System.Data/DataSet.cs: Remove [Serializable] attributes from
+	methods, those only apply to structs or classes.
+
+	Stub out ISerializable, ISupportInitialize, and IListSource methods 
+	
+	* System.Data/DataRowView.cs: Stub out interface methods for
+	IEditableObject, ICustomTypeDescriptor and IDataErrorInfo
+
+	* System.Data/DataView.cs: Comment out non-implemented
+	interfaces. 
+
+	* System.Data/DataViewSettingsCollection.cs: Type cast variables
+	to the correct type to make it compile.
+
+	* System.Data/DataViewSettings.cs: remove reference to
+	non-existance type ApplyDefaultSort, it is a boolean.
+

+                Various fixes, including adding the SqlNullValueException
+                when trying to retrieve the value of a null SqlType,
+                and when casting values, a Null of type A converts to a

+
+2002-05-04  Daniel Morgan <danmorg@sc.rr.com>
+	
+	* System.Data.SqlClient/PostgresLibrary.cs
+	* System.Data.SqlClient/SqlCommand.cs
+	* System.Data.SqlClient/SqlConnection.cs
+	* System.Data.SqlClient/SqlDataReader.cs
+	oid should not be hard coded because they
+	can change from one version of PostgreSQL
+	to the next.  Use the typname's instead.
+	The PostgreSQL type data retrieves
+	at database connection time.  Any unimplemented
+	types just default to string.  These were things
+	suggested by Gonzalo.
+	
+	* Test/ReadPostgresData.cs - stuff
+	* Test/TestSqlDataReader.cs - stuff
+	
+	* System.Data.SqlTypes/SqlInt32.cs - added a using

+
+	* Test/TestExecuteScalar.cs: added test for 
+	method ExecuteScalar in class SqlCommand.
+	
+	* System.Data/DataColumnCollection.cs - it should

+	
+	* System.Data/DataColumn.cs
+	* System.Data/DataTable.cs: tweaks to retrieve
+	meta data from the database

+	
+	* System.Data.SqlClient/SqlCommand.cs: implemented

+	varchar ==> String.  Other types
+	will come later.
+	
+	* System.Data.SqlClient/SqlConnection.cs: added comment
+	
+	* System.Data.SqlClient/SqlDataReader.cs: implemented

+2002-05-02  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.SqlClient/PostgresLibrary.cs: included new 
+	internal class that will be a helper class in using
+	PostgreSQL.  PostgresLibrary is used for the 
+	pinvoke methods to the PostgreSQL Client
+	native C library libpq while the class PostgresHelper 
+	is used for	wrapper or helper methods.  It currently only
+	has one static method OidTypeToSystem in converting
+	PostgreSQL types to .NET System.<type>s, such as,
+	a PostgreSQL int8 becomes a .NET System.Int64.
+	Only a few types have been added, such as, int2,
+	int4, int8, varchar, text, bool, and char.  Other types
+	will come later.
+	
+	* System.Data.SqlClient/SqlCommand.cs: implemented
+	method ExecuteScalar which allows us to do aggregate
+	functions, such as, count, avg, min, max, and sum.  We
+	also are able to retrieve the result, convert it to the .NET type
+	as an object.  The user of the returned object must explicitly cast.
+	
+	* Test/ReadPostgresData.cs: updated sample
+	to help us learn to retrieve data in System.Data.SqlClient
+	classes
+
+2002-05-01  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.build: added /nowarn: nnnn arguments 
+	so you will not get a ton of warnings.  The warnings
+	being excluded are: 1595, 0067, 0109, 0169, and	0649
+
+2002-05-01  Daniel Morgan <danmorg@sc.rr.com>
+

+
+	* System.Data.build: excluded new files from build.
+
+2002-04-29  Daniel Morgan <danmorg@sc.rr.com>
+
+	* Test/ReadPostgresData.cs: added - Uses the 
+	PostgresLibrary to retrieve a recordset.
+	This is not meant to be used in Production, but as a
+	learning aid in coding 
+	class System.Data.SqlClient.SqlDataReader.
+	This sample does work.
+	
+	* Test/TestSqlDataReader.cs: added - used
+	to test SqlDataReader (does not work yet)
+	Forgot to add to ChangeLog on last commit.
+
+2002-04-28  Rodrigo Moya <rodrigo@ximian.com>

+2002-04-28  Rodrigo Moya <rodrigo@ximian.com>
+
+	* System.Data/DataViewManager.cs: new class.

+
+	* System.Data.SqlTypes/SqlInt32.cs:
+	* System.Data.SqlTypes/SqlString.cs:
+	* System.Data.SqlTypes/SqlBoolean.cs: removed destructor, since
+	these are strctures.
+
+	* System.Data.SqlClient/SqlClientPermissionAttribute.cs: added
+	missing 'using's.
+	
+2002-04-28  Rodrigo Moya <rodrigo@ximian.com>
+	
+	* System.Data/DataTableRelationCollection.cs: use 'new' keyword
+	for correctly hiding parent class' members.
+	(AddRange): use 'override' keyword on overriden method.

+	* System.Data/ForeignKeyConstraint.cs
+	* System.Data/UniqueConstraint.cs: added more stubs
+	
+	* System.Data/DataTableRelationCollection.cs: added back to cvs
+	and modified for compile errors.  DataRelationCollection is an
+	abstract class and there must be a class that implements for
+	DataTable/DataSet.  DataTableRelationCollection was changed
+	to an internal class.
+	
+	* System.Data.build: modified - new files added
+	also wanted to include files/classes in the build 
+	so we can get a compilable forward read only result set.
+	It compiles now using csc/nant with warnings, but this 
+	is a start for adding functionality for the result set.  
+	Classes associated with/and DataSet are still excluded.

+	
+	* System.Data/DataTable.cs: modified - temporarily commented

+	DataTable, and dependencies for a forward read-only result set.
+	SqlDataAdapter, DataSet, and DataView will come later once we can get
+	a forward read only result set working.
+	
+	* System.Data/IDataRecord.cs: modified - source code lines should
+	not be > 80
+	
+	* System.Data/InternalDataCollectionBase.cs: modified - started 
+	implementing this base class for collection of data rows,
+	columns, tables, relations, and constraints
+	
+	* System.Data.SqlClient/SqlException.cs: modified -
+	call base(message) so a unhandled exception displays
+	the message of a SQL error instead of the 
+	default SystemException message
+	
+	* Test/TestSqlException.cs: modified - 
+	handle the rollback properly for a SqlException on a
+	failure to connect

+	Also, got rid of compile warnings for hostaddr and port.
+
+	* System.Data.SqlClient/SqlErrorCollection.cs: modified - got

+System.Data TODO List
+=====================
+
+Update this file as needed...
+
+* To get ExecuteReader() in a SqlCommand object to return 
+  a SqlDataReader object which can Read() data and get a String or
+  Int32 from the database.  Other types can be done later.
+  
+  A class (SqlDataReader) that implements IDataReader/IDataRecord
+  only has one row in memory at a time.
+
+In order to do this, we need to compile and edit these classes:
+	SqlDataReader	DataTable	DataRowCollection		DataRow
+								DataColumnCollection	DataColumn
+								DataConstraintCollection DataConstraint
+								DataRelationCollection	DataRelation
+								DataTableCollection
+	and dependencies...
+
+System.Data.Common classes that need to be implemented:
+ - implement DataAdapter.cs
+ - implement DataColumnMapping.cs
+ - implement DataColumnMappingCollection.cs
+ - implement DataTableMapping.cs
+ - implement DataTableMappingCollection.cs
+ - implement DbDataAdapter.cs
+ - implement DbDataPermission.cs
+ - implement DbDataPermissionAttribute.cs
+ - implement RowUpdatedEventArgs.cs
+ - implement RowUpdatingEventArgs.cs
+
+The following classes implement InternalDataCollectionBase:
+	* DataRowCollection
+	* DataColumnCollection
+	* DataTableCollection
+	* DataRelationCollection - an abstract class used by DataTable and DataSet
+	* ConstraintCollection
+
+DataTableRelationCollection is an internal class that implements DataRelationCollection
+and is used by DataTable for parent/child relations.  Don't know if it will/will not
+be used by DataSet.
+
+Other classes, structs, etc. that are missing:
+	DataRowView
+	DataSysDescriptionAttribute
+	DataViewManager
+	DataViewSetting
+	FillErrorEventArgs
+	MergeFailedEventArgs
+	TypedDataSetGenerator
+ 
+The additional System.Data.SqlTypes classes need to be implemented:
+	SqlByte
+	SqlDataTime
+	SqlDecimal
+	SqlDouble
+	SqlGuid
+	SqlInt16
+	SqlInt64
+	SqlMoney
+	SqlSingle
+
+* provide a standard scheme for storing
+  connection string data
+
+* allow Execute methods in SqlCommand to
+  call a stored procedure
+
+* Create a script for testing System.Data:
+  - calls script to create 
+    a test database named monotestdb
+  - set up nunit for testing System.Data
+  - set up System.Data.Config or some other 
+    file to hold connection strings and other
+    configuration settings for the testing System.Data
+  - any other stuff needed...
+
+* get SqlParameter/SqlParameterCollection
+  working so you can:
+  - for queries/commands that have parameters:
+    o  input 
+    o  output 
+    o  return
+    o  input/output
+  - call a stored procedure with parameters
+ 
+* be able to return a XmlReader from
+  using method ExecuteXmlReader of
+  a SqlCommand object
+
+* get SqlDataAdapter/DataSet working
+
+* Create Library for PInvoking into libgda
+  This will be used by System.Data.OleDb classes
+
+* Begin System.Data.OleDb classes:
+  - OleDbConnection
+  - OleDbCommand
+  - OleDbTransaction
+
+* Do more of the OleDb classes to
+  retrieve a OleDbDataReader object
+  from a query (SELECT FROM):
+  - OleDbDataReader
+  - others...
+
+* Do more OleDb classes for DataSet:
+  - OleDbDataAdapter
+  - others...
+  
+* Security Audit of System.Data
+
+* Create a MySQL ADO.NET Provider
+
+* Create an Oracle ADO.NET Provider
+
+* Create an Interbase ADO.NET Provider
+
+* Create a Sybase ADO.NET Provider (TDS?)
+
+* Create an IBM UDB DB2 ADO.NET Provider
+
+* Create other ADO.NET providers...
+
+Integration
+===========
+
+* get System.Data to work with ASP.NET's
+  System.Web.UI.WebControls.DataGrid
+
+* get System.Data to work with GUI
+  System.Windows.Forms.DataGrid
+

+
+2002-05-11  Daniel Morgan <danmorg@sc.rr.com>
+
+	* Test/PostgresTest.cs: added call to PostgreSQL stored procedure
+	version() which returns the version of the PostgreSQL DBMS you

+	goes to Gonzalo.
+
+2002-05-11  Daniel Morgan <danmorg@sc.rr.com>
+
+	* AllTests.cs: needed a using for System.Data and System.Data.SqlClient,

+
+2002-05-06  Daniel Morgan <danmorg@sc.rr.com>
+
+	* System.Data.SqlTypes.SqlInt32Test.cs: missing

+//                    Currently, only working on a command line interface for SqlSharp
+//
+//                    However, once GTK# and System.Windows.Forms are good-to-go,
+//                    I would like to create a SqlSharpGui using this.
+//
+//                    It would be nice if this is included as part of Mono
+//                    extra goodies under Mono.Data.SqlSharp.
+//
+//                    Also, this makes a good Test program for Mono System.Data.
+//                    For more information about Mono::, 
+//                    visit http://www.go-mono.com/
+//
+// To build SqlSharpCli.cs:
+// $ mcs SqlSharpCli.cs -r System.Data.dll -r Mono.Data.MySql.dll
+//
+// To run with mono:
+// $ mono SqlSharpCli.exe
+//
+// To run with mint:
+// $ mint SqlSharpCli.exe
+//
+// To run batch commands and get the output, do something like:
+// $ cat commands.txt | mono SqlSharpCli.exe > results.txt

+// Test/ExecuteScalar.cs

+//

+// Test the ExecuteScalar method in the 

+// System.Data.SqlClient.SqlCommand class

+//

+// ExecuteScalar is meant to be lightweight

+// compared to ExecuteReader and only

+// returns one column and one row as one object.

+//

+// It is meant for SELECT SQL statements that

+// use an aggregate/group by function, such as,

+// count(), sum(), avg(), min(), max(), etc...

+// 

+// The object that is returned you do an

+// explicit cast.  For instance, to retrieve a

+// Count of rows in a PostgreSQL table, you

+// would use "SELECT COUNT(*) FROM SOMETABLE"

+// which returns a number of oid type 20 which is 

+// a PostgreSQL int8 which maps to 

+// the .NET type System.Int64.  You

+// have to explicitly convert this returned object

+// to the type you are expecting, such as, an Int64

+// is returned for a COUNT().

+// would be:

+//      Int64 myCount = (Int64) cmd.ExecuteScalar(selectStatement);

+2002-07-18  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* Color.cs: implemented SystemColors and NamedColors properties that
+	are used by ColorConverter, removed public constructor, use
+	SystemColors, and misc. fixes to make it behave as MS (ToString,
+	parsing names, FromKnownColor,...).
+
+	* ColorConverter.cs: use NamedColors and SystemColors from Color when
+	trying to get the color from its name.
+
+	* SystemColors.cs: new file.
+
+2002-07-16  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* Color.cs: changed static properties to use FromArgbNamed. Also
+	modified the program included in comments that get the values for
+	static properties.
+
+	(FromArgbNamed): build named colors.
+	(FromKnownColor): fixed.
+	(FromName): use a hash to look up colors by name.
+	(FillColorNames): create the hash of colors.
+	(Equals): compare values and name.
+	(ToString): improved.
+
+	* ColorTranslator.cs: implemented ToHtml.
+
+2002-06-20  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* Color.cs: added TypeConverter attribute.
+	
+	* ColorConverter.cs: added constructor.
+
+2002-06-15  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* ColorConverter.cs: implemented minimal set of features needed by xsp.
+
+2002-05-03  Mike Kestner <mkestner@speakeasy.net>
+
+	* Bitmap.cs : using System.IO
+	* ColorTranslator.cs : Stubbed off build breakers.
+	* Image.cs : Stub off IDisposable and ICloneable.
+	
+2002-04-27  Christian Meyer  <Christian.Meyer@cs.tum.edu>
+
+	* Bitmap.cs: Ximian is the new copyright holder now.
+	* Image.cs: ditto
+
+2002-04-05  Christian Meyer  <Christian.Meyer@cs.tum.edu>
+
+	* Uppercased several files.
+
+2002-04-05  Christian Meyer  <Christian.Meyer@cs.tum.edu>
+
+	* color.cs: Fixed a typo in GetSaturation ().
+
+2002-02-26  Christian Meyer  <Christian.Meyer@cs.tum.edu>
+
+	* Bitmap.cs: Added method headers.
+
+2002-02-25  Christian Meyer  <Christian.Meyer@cs.tum.edu>
+
+	* Bitmap.cs: Added, no implementation's done, yet.
+
+2001-12-15  Mike Kestner <mkestner@speakeasy.net>

+2002-07-23  Tim Coleman <tim@timcoleman.com>
+	* WebService.cs: 
+		Change Description to WebServicesDescription
+	* WebServicesDescriptionAttribute.cs:
+		Add back constructor as MS build doesn't
+		seem to like it missing.  Now calls base()
+		with the string.  Also remove the sealed
+		modifier and change the attribute targets.
+
+2002-07-23  Tim Coleman <tim@timcoleman.com>
+	* WebServicesDescriptionAttribute.cs:
+		Removed the "guts" because they are defined in
+		System.ComponentModel.DescriptionAttribute.
+	* WebService.cs:
+		Added attributes which were missing based on the
+		class status page.  Also added an HttpApplication
+		object and modified the properties to use that
+		object.
+
+2002-07-22 Tim Coleman <tim@timcoleman.com>
+	* WebServicesDescriptionAttribute.cs:
+		Added for build in System.Web.Services.Protocols
+
+2002-07-22  Tim Coleman <tim@timcoleman.com>
+	* WebMethodAttribute.cs: 
+		Remove comments around TransactionOption bits
+		because I added that enum.
+	* WebServiceAttribute.cs:
+	* WebServiceBindingAttribute.cs:
+		Added "sealed" to protection level, which I missed
+		before.

+	* RepeaterItem.cs          - Completed.
+	
+	 Oh God! Mercy! I will die applying attributes. I look at the missing
+	  part in the class-status - daemon! Kyrie eleison!
+
+2002-03-19      Gaurav Vaish <gvaish@iitk.ac.in>
+

+
+2002-03-17      Gaurav Vaish <gvaish@iitk.ac.in>
+
+	Finally, I have made it. Today I did a second build for the
+	 System.Web assembly. It compiled 195 classes today.
+	I am waiting eagerly for the runtime to come up so that the objects
+	 may be tested to their last levels. Several of the methods are still
+	 under the tag of "TODO" throwing NotImplementedException. Well, I
+	 hope to remove them soon, but how far is this soon - even I don't
+	 know, though I am happy to make the build a success even before
+	 the vacations to come.
+
+2002-03-07      Gaurav Vaish <gvaish@iitk.ac.in>
+
+	Yesterday and today I tried to do some building of the aseembly,
+	 but was dumped with uncoutably infinite errors. ;-)
+	I have put the copies of the recent errors on my home page, want
+	 to have a look at them? See:
+	  http://mastergaurav.virtualave.net/mono/
+	I don't know what to do with these errors. Oh! The buggy me! How
+	 will I overcome myself. Hopefully, by when my vacations over, I
+	 should have made a repository where the build will not fail.
+
+2002-03-05      Gaurav Vaish <gvaish@iitk.ac.in>
+
+	I am now going to do a build that will include the
+	 System.Web.UI.WebControls namespace. Hoping that I will make it
+	 soon. My exams are coming near and I have to pack up soon.
+
+
+2002-03-04      Gaurav Vaish <gvaish@iitk.ac.in>
+
+Comments:
+	And with this, ie, today's work, all the objects mentioned in the
+	namespace appear in the implementation. But it may not be worth
+	trying to go for a build because of dependence of several of the
+	internal methods that may clash with already available assembly
+	System.Web.
+	
+	Also, the classes lack possible attributes, like those informing
+	about child-controls etc. But I have to first create the attribute
+	classes before I attach the attributes to the classes.
+
+	* CustomValidator.cs          - Completed. In process realized that
+	             I have to complete / rejuvinate BaseValidator class.
+	* BaseValidator.cs            - Complete rejuvination. Completed 80%
+	            of the job. All that is left is Render(HtmlTextWriter),
+	            DetermineRenderUplevel(), RegisterValidatorCommonScript()
+	            RegisterValidatorDeclaration()
+	* DataGridPagerStyle.cs       - Completed. That adds one more missle
+	            in my artillery.
+	* DataKeyCollection.cs        - Completed. Petty small.
+	* Repeater.cs                 - Work started off. This is a quite
+	            heavy class. Hooh!
+	* DataGridItemEventArgs.cs,
+	* DataGridShortCommandEventArgs.cs,
+	* DataListItemEventArgs.cs,
+	* MonthChangedEventArgs.cs,
+	* RepeaterItemEventArgs.cs,
+	* ServerValidateEventArgs.cs,
+	* DataGridPageChangedEventArgs.cs
+	                              - Damn, I marked them "*", while they
+	            did not exist.
+	* Repeater.cs                 - Done all except for an undocumented
+	            method CreateControlHierarchy(bool). Though the method
+	            is quite clear by its name, but it will take some time
+	            for me to come with some material to flush in.
+
+2002-03-03      Gaurav Vaish <gvaish@iitk.ac.in>
+
+	* SelectedDatesCollection.cs  - Completed.
+	* PagedDataSource.cs          - Completed. Pathetically nice class.
+	* RegularExpressionValidator.cs
+	                              - Completed. Ridiculously small and
+	            annoyinglyc crazy-driving class, basically the method
+	            EvaluateIsValid().
+	* RangeValidator.cs           - Completed.
+	* DataGridColumn.cs           - Completed.
+	* EditCommandColumn.cs        - All is complete except for the
+	            InitializeCell(TableCell, int, ListItemType) method.
+	* DataListItem.cs             - All done except for a longish method
+	            RenderItem(HtmlTextWriter, bool, bool)
+
+2002-03-02      Gaurav Vaish <gvaish@iitk.ac.in>
+
+	* RepeaterItemCollection.cs   - Completed.
+	            I love *Collection classes. I am planning to make a
+	            program that will generate a *Collection class. It's so
+	            simple and the same. ;-)
+	* DataGridColumnCollection.cs - Completed.
+	            ... except probably for *ColumnCollection classes, where
+	            you have to put in some more effort. Still, these class
+	            generation can be automated.
+	* DataListItemCollection.cs   - Completed.
+	            See, how easily, in less than a quarter of a minute, I
+	            completed this class - manually. Copy-Paste/Cut-Replace.
+

+	         Addded support for properties:
+	           GridLines, HeaderStyle, HeaderTemplate, ItemStyle, ItemTemplate,

+	           PrepareControlHierarchy(), InitializeItem(DataListItem)

+
+

+
+	* RepeaterInfo.cs             - Initial Implementation. Done all

+
+	* ControlCollection.cs:

+

+	Probably also needed in HtmlContainerControl derived classes.
+

+	Invoke Page_Init and/or Page_Load if the user supplied them (though 
+	this should depend on AutoEventWireUp attribute of Page directive).
+
+2002-06-04  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* Control.cs: don't throw exception in ControlID. By now, it returns ID.

+//notes: view state only tracks changes after OnInit method is executed for the page request. You can read from it at any time, but cant write to it during rendering.

+//even more notes: view state info in trackviewstate method description. read later.

+//Ok, enough notes: what the heck is different between enable view state, and track view state.

+//Well, maybe not. How does the ViewState know when to track changes? Does it look at the property

+//on the owning control, or does it have a method/property of its own that gets called?

+// I think this last question is solved in the Interface for it. Look into this.

+

+//cycle:

+//init is called when control is first created.

+//load view state ic called right after init to populate the view state.

+//loadpostdata is called if ipostbackdatahandler is implemented.

+//load is called when control is loaded into a page

+//raisepostdatachangedevent if ipostbackdatahandler is implemented.

+//raisepostbackevent if ipostbackeventhandler is implemented.

+//prerender is called when the server is about to render its page object

+//SaveViewState is called.

+//Unload then dispose it apears. :)

+2002-01-03  Nick Drochak  <ndrochak@gol.com>

+

+	* FileChangesMonitor.cs: remove redundant using statement; use int

+	for MAXLEN; capitalize correctly 'WebHashCodeProvider';

+	fix typo rsLock -> rwLock; Change IsRooted to IsPathRooted;

+	set out parameter value where needed

+	* FilePathParser.cs: qualify method GetPathRoot() with 'Path.'

+	* IISVersionInfo.cs: initialize static member to avoid compile error.

+	* WebEqualComparer.cs: static member defC shouldn't be readonly;

+	the string comparer had some typos (fixed)

+	* WebHashCodeProvider.cs: needed System.Globalization; static member

+	defHcp shouldn't be readonly; remove double equal typo.

+

+2002-01-02  Nick Drochak  <ndrochak@gol.com>

+

+	* FileAction.cs: Use 0x7FFFFFFF as enum value for error.  0xFFFFFFFF

+	is too big for Int32.

+	* FileChangeEventHandler.cs: put missing 'void' return type on delegate

+	FileChangeEventHandler()

+	* FileChangedEventArgs.cs: ditto for FileChangedEvent()

+	* NativeFileChangeEventHandler.cs: ditto for NativeFileChangeEventHandler()

+	* FileChangesMonitor.cs: add needed namespaces and comment out imcomplete

+	code.

+Found another namespace not listed. System.Web.Hosting.
+HttpRuntime.ProcessRequest and HttpWorkerRequest seems to be the key. 
+
+ASP maintains a pool of HttpApplication objects dirived from Global.asax.
+One is used per request, then reclamed after the request is totally
+complete.
+
+Read:
+http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguidnf/html/cpconaspnetapplications.asp
+
+
+Request notes:
+It apears each http request has its own thread. Need to figure out how to deal with this with apache.
+
+Session notes:
+When a request is finished, the contents of Request.Session are serialized and dumped to the State Server.
+When a request is started, a new Request.Session is created, data is deserialized from the State Server, and the objects are placed back into Request.Session.
+The State Server is accessed via the SessionStateModule which is used for both session ID and state data management.
+HttpApplicationState instance is created the first time a url within the applications virtual directory is accessed. Its accessable through HttpContext.Application.
+HttpApplicationState needs to use lock/unlock explicitly.
+Not shared across machines or multiple processes.

+BUGS in MS Implementation of XmlSchema:

+

+1. Does not allow duplicate values in lists for final* and block* attributes. 

+   For example "restriction restriction" is not allowed even though its a valid

+   value for blockDefault.

+

+2. Resets the minOccurs to 0 if maxOccurs="0", whereas it should raise an error.

+

+3. Allows abstract="true" in the a localElement whereas it is not allowed.

+Bugs in Implementation:

+

+// None of the XmlSchemaObjects except the XmlSchema populate XmlSerializerNamespaces.

+//2. Non schema attributes are not being handled. Need an internal XmlAttribute constructor.

+//3. Documentation and appInfo's Markup is not being read in the Read() Method.

+2002-07-23  Duncan Mak  <duncan@ximian.com>
+
+	* XmlSchemaException.cs: Partiall implement the ISerializable
+	methods. It's not clear now SourceSchemaObject should be deserialized.
+
+2002-07-22  Tim Coleman  <tim@timcoleman.com>
+	* XmlSchema.cs: Removed isCompiled which is defined as internal
+		in XmlSchemaObject.
+
+2002-06-18  Dwivedi, Ajay kumar <adwiv@yahoo.com>
+	
+	* XmlSchema: Started work on Validate methods
+
+2002-06-18  Dwivedi, Ajay kumar <adwiv@yahoo.com>
+	* XmlSchema: The Read and Write methods are no more [MonoTODO] :)
+	
+	* XmlSchemaAppInfo: Xml Markup is now being read.
+	
+	* XmlSchemaDocumentation: Xml Markup is now being read.
+
+	* All: Unhandled attributes are being handled properly.
+	       
+	* All: Reordered the properties in all cs files to match with MS
+	       Implementation. This was required since the order is importatnt
+	       for the XmlSerializer.
+	
+2002-06-14  Dwivedi, Ajay kumar <adwiv@yahoo.com>
+	* General: Fixed a few more Bugs
+
+2002-06-10  Dwivedi, Ajay kumar <adwiv@yahoo.com>
+	* XmlSchemaReader: A Wrapper class around XmlReader with customized
+	  methods to suit reading a schema.
+	* General: Implemented Read() method for the schema. There are only
+	  a few minor bugs remaining.
+
+2002-05-25  Dwivedi, Ajay kumar <adwiv@yahoo.com>
+	* BUGS.txt: New file to keep track of bugs
+
+	* ALL: All classes are initialized exactly as in .NET except
+	       1. inclusion of language attribute in schema
+	       2. ComplexContent's Particle is initialized to null whereas .NET 
+	          to some internal implementation. IMO Null is more appropriate
+
+	* ALL: Changed the Compile methods to return the count of errors.
+
+	* ALL: Complile methods are almost complete. Pass 1453 of 3061 tests.
+	       This number should shoot up if we write a parser to read the
+	       Schema instead of using reflection (which is slower too)
+
+2002-05-04  Dwivedi, Ajay kumar <adwiv@yahoo.com>
+	* XmlSchemaUtil.cs: New file added. 
+	
+	* Parser.cs: New file Added. Unused at the moment.
+
+	* XmlSchemaObjectCollection: Fixed GetEnumerator
+	
+	* General: Preprocessing for Attributes and SimpleTypes completed.
+
+2002-04-26  Duncan Mak  <duncan@ximian.com>
+
+	* ValidationHandler.cs: New file.
+
+	* XmlSchemaInfo.cs: New file.
+
+	* *.cs: More updates from Ajay.

+	* XPathNodeType.cs:
+	* XPathResultType.cs:

+
+	* XmlDataType.cs, XmlSortOrder.cs, XPathNodeType.cs: Added files.

+2002-07-26  Tim Coleman <tim@timcoleman.com>
+	* XmlTextWriter.cs:
+		When given a textwriter, check to see if it has a
+		null encoding. This was being done for other inputs
+		than a textwriter.
+
+Wed Jul 24 13:16:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* XmlTextReader.cs: rough line/column support.
+
+2002-07-23  Duncan Mak  <duncan@ximian.com>
+
+	* XmlConvert.cs: Implement the ToDateTime method. ToDateTime
+	(string, string []) is particularly strange.
+
+	* XmlException.cs: Remember to call the base serialization
+	constructor.
+
+	* XmlNodeReader.cs: Keep a new variable to store the Depth. 
+
+2002-07-14  Jason Diamond  <jason@injektilo.org>
+
+	* XmlAttribute.cs: Removed ownerElement field since we can reuse 
+	parentNode field.
+
+	* XmlDocumentNavigator.cs: MoveToParent now moves to the OwnerElement
+	if the current node is an attribute.
+
+	* XmlElement.cs: SetAttributeNode now sets the new attribute's
+	owner element.
+
+2002-07-12  Jason Diamond  <jason@injektilo.org>
+
+	* XmlDocument.cs: If null was passed in for prefix or namespaceURI when
+	creating an element, use String.Empty instead.
+
+2002-07-12	Piers Haken <piersh@friksit.com>
+
+	* XmlAttributeCollection.cs: implement some ItemOf indexers
+	* XmlNamedNodeMap.cs: add internal 'Nodes' accessor for the nodeList field
+	* XmlNode.cs: SelectNodes: return empty XmlNodeList, not null
+
+2002-07-06  Ajay kumar Dwivedi <adwiv@yahoo.com>
+
+	* XmlTextWriter: Fixed Indentation. IndentationOverridden should
+		not be set when inside a attribute.
+
+2002-07-06  Ajay kumar Dwivedi <adwiv@yahoo.com>
+
+	* XmlTextWriter: In WriteStartElement, if namespace is null and 
+		prefix is null|empty do not write out xmlns=""
+	
+	* XmlWriter: WriteStartElement calls the virtual method with null
+		argument instead of empty string.
+
+2002-07-05  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* XmlTextReader.cs: implemented .ctor (Stream).
+
+2002-06-26  Duncan Mak  <duncan@ximian.com>
+
+	* XmlNodeReader.cs: Implementation of most of the properties, and

+2002-01-31  Duncan Mak  <duncan@ximian.com>
+
+	* ConfigurationException.cs: Rewrote most of the file and added
+	serialization bits.
+
+2002-01-06  Ravi Pratap  <ravi@ximian.com>
+
+	* ConfigurationSettings.cs, IgnoreSectionHandler.cs : MonoTODO decoration
+
+	* SingleTagSectionHandler.cs, DictionarySectionHandler.cs, 
+	NameValueSectionHandler.cs : Ditto.
+
+2001-08-28  Christopher Podurgiel <cpodurgiel@msn.com>
+	* IConfigurationSectionHandler.cs: Added reference to System.Xml.
+	
+	* SingleTagSectionHandler.cs: Added Implementation of Create() method.
+	
+	* NameValueSectionHandler.cs: Added Implementation of Create() method.
+	
+	* ConfigurationException.cs: Now returns proper message rather than "System Exception".
+
+2001-08-26  Christopher Podurgiel <cpodurgiel@msn.com>
+
+	* ConfigurationSettings.cs: No longer references the NameValueSectionHandler 	  directly.  Instead it uses System.Reflection to call the Create() method 		  for the appropriate SectionHandler as defined in the .config file.

+
+	* IPAddress.cs: Fix constructor bug, properly name Address property,
+	and use triple-slash for comments.
+
+2001-11-20  Miguel de Icaza  <miguel@ximian.com>
+
+	* IPAddress.cs: Updated to contain Any, Broadcast, Loopback and
+	None as suggested by Phillip.
+
+2001-09-26  Mads Pultz <mpultz@get2net.dk>
+	* Dns.cs: Initial work on BeginGetHostByName and EndGetHostByName implemented.
+
+2001-09-24  Mads Pultz <mpultz@get2net.dk>

+	//

+	// Flags:	[Negate, IgnoreCase, RightToLeft]

+	// LO:		lowest character in set

+	// LEN:		number of words in set

+	// SET:		bit array representing characters in set

+	//

+	// Notes:

+	//

+	// Each word in the set represents 16 characters, so the first word

+	// defines membership for characters LO to LO + 15, the second for

+	// LO + 16 to LO + 31, and so on up to LO + (LEN * 16 - 1). It is

+	// up to the compiler to provide a compact representation for sparse

+	// unicode sets. The simple way is to use Set 0 4096. Other methods

+	// involve paritioning the set and placing the components into an

+	// In block.

+

+	// In SKIP

+	//

+	// SKIP:	relative address of tail expression

+	//

+	// Usage:	[expr]

+	// Usage:	[^expr]

+	//

+	//	In :1

+	//		<expr>

+	//		False

+	// :1	<tail>

+	//

+	// Notes:

+	//

+	// The In instruction consumes a single character, using the flags

+	// of the first instruction in the subexpression to determine its

+	// IgnoreCase and RightToLeft properties. The subexpression is then

+	// applied to the single character as a disjunction. If any instruction

+	// in the subexpression succeeds, the entire In construct succeeds

+	// and matching continues with the tail.

+

+	// Position POS

+	//

+	// POS:		position to match (see Position enum)

+

+	// Open GID

+	//

+	// GID:		number of group to open

+TODO:
+
+* Need to go through everything and square it with RightToLeft matching.
+  The support for this was built into an early version, and lots of things built
+  afterwards are not savvy about bi-directional matching. Things that spring to
+  mind: Regex match methods should start at 0 or text.Length depending on
+  direction. Do split and replace need changes? Match should be aware of its
+  direction (already applied some of this to NextMatch logic). The interpreter
+  needs to check left and right bounds. Anchoring and substring discovery need
+  to be reworked. RTL matches are going to have anchors on the right - ie $, \Z
+  and \z. This should be added to the anchor logic. QuickSearch needs to work in
+  reverse. There may be other stuff.... work through the code.
+
+* Add ECMAScript support to the parser. For example, [.\w\s\d] map to ECMA
+  categories instead of canonical ones [DONE]. There's different behaviour on
+  backreference/octal disambiguation. Find out what the runtime behavioural
+  difference is for cyclic backreferences eg (?(1)abc\1) - this is only briefly 
+  mentioned in the spec. I couldn't find much on this in the ECMAScript
+  specification either.
+
+* Octal/backreference parsing needs a big fix. The rules are ridiculously complex.
+
+* Add a check in QuickSearch for single character substrings. This is likely to
+  be a common case. There's no need to go through a shift table. Also, have a
+  look at just computing a relevant subset of the shift table and using an
+  (offset, size) pair to help test inclusion. Characters not in the table get
+  the default len + 1 shift.
+
+* Improve the perl test suite. Run under MS runtime to generate checksums for
+  each trial. Checksums should incorporate: all captures (index, length) for all
+  groups; names of explicit capturing groups, and the numbers they map to. Any
+  other state? RegexTrial.Execute() will then compare result and checksum.
+
+* The pattern (?(1?)a|b). It should fail: Perl fails, the MS implementation
+  fails, but I pass. The documentation says that the construct (?(X)...) can be
+  processed in two ways. If X is a valid group number, or a valid group name,
+  then the expression becomes a capture conditional - the (...) part is
+  executed only if X has been captured. If X is not a group number or name, then
+  it is treated as a positive lookahead., and (...) is only executed if the
+  lookahead succeeds. My code does the latter, but on further investigation it
+  appears that both Perl and MS fail to recognize an expression assertion if the
+  first character of the assertion is a number - which instead suggests a
+  capture conditional. The exception raised is something like "invalid group
+  number". I get the feeling the my behaviour seems more correct, but it's not
+  consistent with the other implementations, so it should probably be changed.

+2002-07-10  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* list:
+	* unix.args: added IObjectHandle.cs.
+
+2002-06-20  Martin Baulig  <martin@gnome.org>
+
+	* unix.args: New file.  This is a mcs response file to compile
+	corlib on GNU/Linux (which doesn't work yet).
+
+2002-04-30  Daniel Stodden  <stodden@in.tum.de>
+
+	* System/Delegate.cs: Implemented Remove()
+	* System/MulticastDelegate.cs: Implementation of RemoveImpl()
+	done. Plus a fix for Equals().
+	* Test/System/MulticastDelegate.cs: Added. Should reflect above
+	changes.
+	
+2002-04-27  Martin Baulig  <martin@gnome.org>
+
+	* corlib.build: Added new "mcs-build" target to compile corlib
+	with mcs. This doesn't work yet - it's just to test mcs to find
+	and fix the remaining bugs.
+
+2002-03-27  Dan Lewis  <dihlewis@yahoo.co.uk>
+
+	* corlib.build: removed seperate windows/linux builds. excluded
+	wrapper and PAL classes from all builds.
+
+2002-03-03  Nick Drochak  <ndrochak@gol.com>
+
+	* corlib.build: Exclude a bunch of interfaces from corlib_res.dll
+	that were preventing the tests from running on Windows.
+
+2002-01-25  Mark Crichton  <crichton@gimp.org>
+
+	* System.Security.Cryptography/RijndaelManaged.cs: added
+	
+	* System.Security.Cryptography/Rijndael.cs: changed constructor
+	to set default values.  Hopefully I did it correctly.
+
+2002-01-23  Miguel de Icaza  <miguel@ximian.com>
+
+	* Unix/Errno.cs: Added
+
+	* Unix/Wrapper.cs: Updated to new Wrapper
+
+2002-01-19  Nick Drochak  <ndrochak@gol.com>
+	
+	* corlib.build: exclude Delegate from corlib_cmp.
+
+2002-01-09  Nick Drochak  <ndrochak@gol.com>
+
+	* corlib.build: Exclude Security Attribute classes that need mcs
+	magic to get them to compile.
+
+2002-01-06  Duco Fijma <duco@lorentz.xs4all.nl>
+	* corlib.build: Removed <excludes> for System.Resources
+
+2002-01-05  Nick Drochak  <ndrochak@gol.com>
+
+	* corlib.build: Have the clean target remove any .pdb files that
+	might be around if we compiled with debug on.
+
+2002-01-05  Nick Drochak  <ndrochak@gol.com>
+
+	* corlib.build: Make new build of corlib_cmp.dll.  This is the same
+	as corlib.dll without Object and ValueType.  It is used by 
+	/mcs/tools/corcompare.exe to compare with mscorlib.
+
+2002-01-03  Nick Drochak  <ndrochak@gol.com>
+
+	* corlib.build: Put the linux target at the top.  I keep changing the 
+	build for windows 'cause it's at the top.  Then when I do make, nothing
+	changes.  It seems like it always takes me half a day to remember
+	that the linux target comes second.  Old age I guess.
+
+	* .cvsignore: ignore corlib.pdb for times when it's built with debug on.
+
+2002-01-02  Nick Drochak  <ndrochak@gol.com>
+
+	* corlib.build: Removed "exclude CodeAccessPermission.cs"
+
+2001-12-11  Duncan Mak  <duncan@ximian.com>
+
+	* ChangeLog: Added "System.Resources" to the exclude list.
+
+2001-12-05  Nick Drochak <ndrochak@gol.com>
+
+	* ChangeLog: Add the change log to this directory
+
+	* corlib.build: Add dependancy on linux target to test target. Need to have the dll before we can test it, right?  Plus is encourages other to try 'make test'.

+2002-07-22  Tim Coleman  <tim@timcoleman.com>
+	* CaseInsensitiveHashCodeProvider.cs: Added missing constructor
+		which was breaking System.Web build on linux
+
+2002-07-05  Sergey Chaban <serge@wildwestsoftware.com>
+
+	* SortedList.cs: Implemented thread-safe wrapper. Changed some
+	args to camelCase.
+
+2002-07-02  Nick Drochak  <ndrochak@gol.com>
+
+	* SortedList.cs: Constructors should use the capacity given regardless 
+	how small. After a Clear() the Capacit should be 16. Since a Dictionary
+	might be used in the constructor, make sure we trap exceptions thrown
+	by the Comparer, like in Add().
+
+2002-06-30  Nick Drochak  <ndrochak@gol.com>
+
+	* SortedList.cs: Many fixed. A lot of checking for null and throwing
+	exceptions.  A few logic bugs fixed as well
+
+2002-06-25   Nick Drochak  <ndrochak@gol.com>
+
+	* Queue.cs (CopyTo): Fix logic for copying the circular array.
+	(Enqueue): Use actual length of array to determine when to grow
+	(QueueEnumerator) Fixed Current to use array length, not capacity, and
+	fixed off-by-one errror in MoveNext().
+
+Tue Jun 4 13:08:43 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* ArrayList.cs: fixed RemoveAt() implementation.
+
+2002-05-27  Nick Drochak  <ndrochak@gol.com>
+
+	* ArrayList.cs (LastIndexOf): Return -1 if searching for null, also
+	fix check of parameters sent to make sure we don't search beyond the
+	beginning of the list.
+	(ListWrapper): Throw exception if called with null.
+	We now pass all unit tests.
+
+2002-05-23  Duncan Mak  <duncan@ximian.com>
+
+	* ArrayList.cs (Wrapper): Preliminary implementation of
+	ArrayList.Wrapper (IList).
+
+2002-05-22  Martin Baulig  <martin@gnome.org>
+
+	* ArrayList.cs: Made count, capacity and dataArray the first three
+	fields in the class.  They're read by the reflection library.
+
+2002-05-21  Lawrence Pit  <loz@cable.a2000.nl>
+
+	* ArrayList.cs: Fixed bug where a capacity of 0 could be reached, 
+	thereby causing problems when trying to add elements.
+
+2002-05-06  Duncan Mak  <duncan@ximian.com>
+
+	* Queue.cs (TrimToSize): Implemented.
+	
+2002-05-05  Nick Drochak  <ndrochak@gol.com>
+
+	* ArrayList.cs: Throw RankException when constructing from a 
+	multi-dimensional array. Confirmed behavior from MS.NET
+
+Thu May 2 15:18:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* ArrayList.cs: make mcs compile again: it's allowed to
+	call arraylist.CopyTo(array, 0) when the length of the array
+	is also 0.
+
+Wed May 1 17:05:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* SortedList.cs: fix RemoveAt () to use the correct length in
+	Array.Copy.
+
+2002-05-01  Nick Drochak  <ndrochak@gol.com>
+
+	* ArrayList.cs (Add & AddRange) : Throw exceptions where needed.

+	pointed out by Jakk Simm's test suite.
+
+2002-03-14  Nick Drochak  <ndrochak@gol.com>
+
+	* ArrayList.cs (FixedSize(ArrayList)): should return an ArrayList. The

+
+2002-03-13  Duncan Mak  <duncan@ximian.com>
+
+	* ArrayList.cs (FixedSize): Changed the return type to IList if

+
+	* Hashtable.cs: Fixed ToPrime () bug. Removed ALLOC_GRAIN.

+
+2002-02-07  Duncan Mak  <duncan@ximian.com>
+

+
+Sat Jan 5 15:56:54 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* Hashtable.cs: the IDictionaryEnumerator returns DictionaryEntries.
+

+
+	* Correct name to MonoTODO everywhere.
+
+2002-01-04  Ravi Pratap  <ravi@ximian.com>

+
+	* CaseInsensitiveHashcodeProvider.cs: Ditto.

+	I changed the build file to include Queue.cs as well.
+
+2001-11-04 Nick Drochak <ndrochak@gol.com>
+	* ArrayList.cs: Fixed "off by one" error when shifting left the array when
+	items are removed.
+
+	* CollectionBase.cs: Added OnValidate(), OnRemove() and OnRemoveComplete()
+	hook methods to the RemoveAt() method.
+
+2001-11-04 Nick Drochak <ndrochak@gol.com>
+	* ArrayList.cs: Added private enumerator class and make GetEnumerator()
+	methods return an instance of it.
+
+Tue Sep 25 18:52:48 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* ArrayList.cs: fix Insert () to check capacity, not count.
+
+Tue Sep 25 16:54:54 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* DictionaryEntry.cs: added.
+
+2001-08-10  Dietmar Maurer  <dietmar@ximian.com>
+
+	* common.src: removed duplicate entries
+
+2001-08-08 Nick Drochak <ndrochak@gol.com>
+
+         * ReadOnlyCollectionBase.cs: Initialized private member.
+         * CollectionBase.cs: Initialized private member.
+	 * common.src : Added ReadOnlyCollectionBase.cs and CollectionBase.cs
+	 * /mcs/class/makefile: Used $(SYSTEMROOT) instead of hard coded //c/winnt
+	 * /mcs/makefile: Used $(SYSTEMROOT) instead of hard coded //c/winnt
+
+2001-08-08 Nick Drochak <nick@jobdragon.com>
+
+         * CollectionBase.cs: Add
+         * ReadOnlyCollectionBase.cs: Add
+         * CollectionBaseTest.cs: Add
+         * ReadOnlyCollectionBaseTest.cs: Add
+
+2001-07-31 Garrett Rooney <rooneg@electricjellyfish.net>
+
+	* StackTest.cs: Add Test case for System.Collections.Stack.  
+	Contributed by Chris Hynes <chrish@assistedsolutions.com>
+
+2001-07-30 Garrett Rooney <rooneg@electricjellyfish.net>
+
+	* Stack.cs: Clone() doesn't need to check if it's synchronized, since 
+	we override it in SyncStack anyway...  
+
+	* Stack.cs: Pop() now shrinks the array if we drop below 1/4 full, to 
+	avoid using massive amounts of memory that are not necessary.  We only 
+	drop to half the current size, which I hope will avoid the 'ping-pong' 
+	effect.
+
+	* Stack.cs: SyncStack.IsReadOnly should return stack.IsReadOnly 
+	instead of just returning false, since we may have a ReadOnly wrapper 
+	in the future (although i can't imagine why).  Thanks to David 
+	Menestrina <dmenest@yahoo.com> for pointing this out.
+
+2001-07-23  Sergey Chaban <serge@wildwestsoftware.com>
+
+	*  Hashtable.cs: Fixed bug in Clear(), the Count wasn't zeroed.
+           From now, Clear() increases modification count.
+           Fixed HCP bug in GetHash(object) - hcp.GetHashCode() was used
+           instead of hcp.GetHashCode(key). This was resulted in the
+           insanely long lookup times when HashCodeProvider was used to
+           construct Hashtable. Added thread-safe wrapper.
+
+2001-07-16  David Menestrina <dmenest@yahoo.com>
+
+         * BitArray.cs: Add
+         * BitArrayTest.cs: Add
+
+2001-07-18  Miguel de Icaza  <miguel@ximian.com>
+
+	* IDictionary.cs (Collections): IDictionary implements ICollection
+	as well.  Thanks Sergey!
+
+2001-07-18  Garrett Rooney  <rooneg@electricjellyfish.net>
+
+	* Stack.cs Removed unnecessary locking from many methods of 
+	SyncStack, removed SyncEnumerator because it was unnecessary, 
+	added a modCount member to Stack and Stack.Enumerator, to 
+	ensure that the Stack has not been modified out form under the 
+	Enumerator, and changed the Enumerator to use a reference to the 
+	stack rather than copying over the contents array.
+
+2001-07-17  David Menestrina  <dmenest@yahoo.com>
+
+        * Added implementation of BitArray.
+
+2001-07-17  Miguel de Icaza  <miguel@ximian.com>
+
+	* Hashtable.cs: Removed call to d.Count in the Hashtable
+	constructor that takes an IDictionary as IDictionary does not
+	provide a Count field.
+
+2001-07-15  Sean MacIsaac  <macisaac@ximian.com>
+
+	* IDictionary.cs: Clear was clear.
+
+2001-07-13  Miguel de Icaza  <miguel@ximian.com>
+
+	* All files: Renamespace things to System.
+
+2001-07-05  Vladimir Vukicevic  <vladimir@ximian.com>
+
+	* ArrayList.cs: initial checkin and implementation
+
+	* ICollection.cs, IComprarer.cs, IDictionary.cs,
+	  IDictionaryEnumerator.cs, IEnumerable.cs, IHashCodeProvider.cs,

+
+	* StackTrace.cs: impl. remaining constructors.
+
+2002-06-18  Dietmar Maurer  <dietmar@ximian.com>
+
+	* StackTrace.cs: use new internal call for constructors, use MS like
+	trace format.
+
+	* StackFrame.cs: impl. constructors using a new internal call.
+
+2002-05-01  Duncan Mak  <duncan@ximian.com>
+
+	* DebuggableAttribute.cs: Added missing AttributeUsage attribute.
+
+2002-04-08  Jonathan Pryor  <jonpryor@vt.edu>
+
+	* Debugger.cs: Added [MonoTODO] attribute to methods; modified IsLogging() 
+		and Log() so that System.Diagnostics.DefaultTraceListener could use them
+		without having NotImplementedException's thrown, as the functionality
+		DefaultTraceListener is using is non-critical.
+
+2002-04-08  Nick Drochak  <ndrochak@gol.com>
+
+	* ConditionalAttribute.cs: Add AttributeUsage attribute for methods.
+
+2002-01-23  Duncan Mak  <duncan@ximian.com>
+
+	* DebuggerStepThroughAttribute.cs:
+	* DebuggerHiddenAttribte.cs: Add to CVS.
+
+2002-01-04  Ravi Pratap <ravi@ximian.com>
+
+	* StackFrame.cs : Use the MonoTODO attribute to mark
+	incomplete code.
+
+	StackTrace.cs : Ditto.
+
+2002-01-04  John R. Hicks <angryjohn69@nc.rr.com>
+	* Moved TraceListener, TextWriterTraceListener, and
+	DefaultTraceListener to System assembly....oops.
+
+2002-01-04  John R. Hicks  <angryjohn69@nc.rr.com>
+
+	* Added TextWriterTraceListener.cs, TraceListener.cs, and 
+	DefaultTraceListener.cs to the build.
+
+2002-01-04  John R. Hicks  <angryjohn69@nc.rr.com>
+
+	* Added Debugger.cs to the build.
+
+2001-09-02  Miguel de Icaza  <miguel@ximian.com>
+
+	* Moved BooleanSwitch, Switch, TraceLevel and TraceSwitch to the
+	System assembly.
+
+	* Added StackFrame.cs and StackTrace.cs to the build.
+
+2001-08-21  Nick Drochak <ndrochak@gol.com>
+
+	* Implemented ConditionalAttribute.cs and DebuggableAttribute.cs
+	
+2001-08-29  Alexander Klyubin <klyubin@aqris.com>
+  
+	* Skeletal implementation of StackFrame and StackTrace classes.
+	The classes must be somehow connected to runtime environment in
+	order to generate proper traces.

+2002-03-23  Martin Baulig  <martin@gnome.org>
+
+	* StreamReader.cs: Always do buffered reading, use 4k blocks.
+	(Read (char[], int, int)): Implemented.
+	(DiscardBufferedData): Implemented.
+
+2002-03-21  Mike Kestner <mkestner@speakeasy.net>
+
+	* StreamReader.cs : Fill out, add buffering, and use encoding.
+
+2002-03-19  Martin Baulig  <martin@gnome.org>
+
+	* StreamWriter.cs (StreamWriter (string)): The default is to override
+	the file, not to append to it.
+	(StreamWriter (string path, bool append)): When appending, seek to the
+	end of the file, otherwise truncate the file to zero length.
+	(Dispose (bool)): Close the internalStream.
+	(Flush): Flush the interalStream.

+	* Stream.cs (NullStream): Do not track position, this beast does
+	nothing in practice.
+
+2002-03-15  Dan Lewis <dihlewis@yahoo.co.uk>
+
+	* SearchPattern.cs: New class. Glob matching code for Directory.
+	* Directory.cs: Changed to use SearchPattern instead of mono_glob_*()
+
+2002/03/15 Nick Drochak <ndrochak@gol.com>
+
+	* DirectoryInfo.cs: Fixed the overloaded GetDirectories and GetFiles.
+	This code seemed to be copied from somewhere, and it was close,
+	but didn't match the docs.  This was the last bit needed to get
+	NAnt to compile with our class libs.
+
+2002-03-12  Duncan Mak  <duncan@ximian.com>
+
+	* EndOfStreamException.cs:
+	* FileLoadException.cs:

+
+	* IOException.cs: Added missing constructors.
+	
+2002-03-07  Nick Drochak  <ndrochak@gol.com>
+
+	* FileMode.cs: Docs don't say this should be explicitly derived from
+	int, so just make it a normal Enum.
+
+2002-03-02  Jason Diamond  <jason@injektilo.org>
+
+	* StringReader.cs: Fixed off-by-one error in Peek() and Read().
+

+Tue Mar 26 20:10:24 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* AssemblyBuilder.cs: use FileMode.Create.
+	* ILGenerator.cs: optimize localbuilder related opcodes.
+	Track parameters to adjust maxstack.
+	* LocalBuilder.cS: use unsigned for position.
+
+2002-03-23  Miguel de Icaza  <miguel@ximian.com>
+
+	* LocalBuilder.cs: Drop the symbol_writer as LocalBuilder fields.
+	Do this lazily in SetLocalSymInfo.
+	
+2002-03-24  Martin Baulig  <martin@gnome.org>
+
+	* ModuleBuilder.cs (GetSymbolWriter): The MonoSymbolWriter's constructor
+	now takes a `string assembly_filename' argument, pass it our fully
+	qualified assembly name.
+
+2002-03-24  Nick Drochak  <ndrochak@gol.com>
+
+	* ILGenerator.cs: Use #if-#endif instead of if(false){} to disable
+	code.  This way there is no compiler warning.
+
+	* TypeBuilder.cs: Removed the returns that came after the throws.
+	This removes a few more compiler warnings. Also marked with MonoTODO
+	all places where we throw NotImplemented exceptions.
+
+2002-03-23  Martin Baulig  <martin@gnome.org>
+
+	* SignatureHelper.cs (GetFieldSignatureHelper, GetLocalSignatureHelper):
+	Implemented.
+
+	* LocalBuilder.cs (LocalBuilder): This internal constructor now takes
+	a ModuleBuilder argument instead of a ISymbolWriter one.

+2002-03-23  Martin Baulig  <martin@gnome.org>
+
+	* ILGenerator.cs (BeginScope, EndScope): Implemented.
+
+2002-03-20  Martin Baulig  <martin@gnome.org>
+
+	* ModuleBuilder.cs (GetSymbolWriter): New internal function. Dynamically
+	loads the default symbol writer, catch all possible exceptions and return
+	null on failure.
+	(ModuleBuilder): Added `bool emitSymbolInfo' argument to this internal
+	constructor; if set, call GetSymbolWriter ().
+	(GetSymWriter): Implemented.
+
+	* LocalBuilder.cs (LocalBuilder): Added ISymbolWriter argument to this
+	internal method.
+	(SetLocalSymInfo): Implemented, call ISymbolWriter.DefineLocalVariable ()
+	if the symbol writer is not null.
+
+	* ILGenerator.cs (ILGenerator): Call ModuleBuilder.GetSymWriter () to get
+	and store the symbol writer.
+	(DeclareLocal): Pass the symbol writer to LocalBuilder's constructor.
+	(MarkSequencePoint): Implemented, call ISymbolWriter.DefineSequencePoints ()
+	if the symbol writer is not null.
+
+	* AssemblyBuilder.cs (DefineDynamicModule): Pass the `bool emitSymbolInfo'
+	to ModuleBuilder's constructor.
+

+
+	* ModuleBuilder.cs: handle modified types correctly.
+
+Thu Mar 7 17:10:42 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* AssemblyBuilder.cs: allow saving bigger assemblies.
+	* ILGenerator.cs: add fixup table for fields and methods, since
+	at the end of the compile they may end up with a different table
+	index.
+	* ModuleBuilder.cs: add cache for type names to speed up the type
+	lookups from the compiler.
+	* TypeBuilder.cs: GetInterfaces () returns only interfaces in the
+	current type, not in parents (the docs are wrong).
+
+Tue Mar 5 18:09:34 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* EventBuilder.cs: implemented.

+Mon Mar 4 20:34:52 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* ILGenerator.cs: make enough room in the byte array for string
+	tokens.
+	* TypeBuilder.cs: fixed GetInterfaces().
+
+Mon Mar 4 11:30:40 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* TypeBuilder.cs: implemented GetConstructors(), GetFields(),
+	GetMethods(), GetProperties().
+
+Thu Feb 28 19:15:10 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* AssemblyBuilder.cs: call into the runtime to init some basic
+	assembly stuff. Reserve slot 1 of typedef table for .<Module>.
+	* ModuleBuilder.cs: call into the runtime if we need to create a
+	modief type, such as arrays, byref etc.

+2002-03-12  Duncan Mak  <duncan@ximian.com>
+
+	* MissingManifestResourceException.cs: This should inherit from
+	SystemException, not Exception.
+
+2002-01-26  Nick Drochak  <ndrochak@gol.com>
+
+	* ResourceReader.cs: Finsished reading resource files with just strings
+	in them.  Need to figure out other types, and also resources with
+	multiple types in the same file.
+
+2002-01-24  Nick Drochak  <ndrochak@gol.com>
+
+	* ResourceReader.cs: Implemented constructors. Started on the 
+	GetEnumerator() method.  Not done yet, but comitting for 
+	'disaster recovery' purposes.
+
+2002-01-19  Duncan Mak  <duncan@ximian.com>
+
+	* *.cs: Fixed indentation. There was a stupid bug in my .emacs file.
+
+2002-1-17  Duncan Mak  <duncan@duncan@ximian.com>
+
+	* ResourceSet.cs: Implemented GetObject (string, bool) and GetString
+	(string, bool). ResourceSet has no more MonoTODOs! Also added in the
+	Serializable attribute.
+	
+	* *.cs: convert to Miguel's brace style.
+
+2002-01-17  Duncan Mak  <duncan@ximian.com>
+
+	* ResourceManager.cs: Fixed GetNeutralResourcesLanguage () and added
+	new attributes documented in 1.0 SDK.
+
+2002-01-17  Duncan Mak  <duncan@ximian.com>
+
+	* ResourceWriter.cs: Added MonoTODO decorations.
+
+	* SatelliteContractVersionAttribute.cs: added new attributes in 1.0 SDK.
+
+	* NeutralResoucesLanguageAttribute.cs: added new attributes in 1.0 SDK
+	
+2002-01-16  Duncan Mak  <duncan@ximian.com>
+
+	* ResourceReader.cs: Fixed some typos.
+
+	* ResourceManager.cs: After reading the tutorial from the SDK,
+	finished all the ResourceManager constructors and removed those
+	MonoTODO tags.
+	
+	Removed MonoTODO from GetNeutralResourcesLanguage (Assembly)
+	because Miguel just implemented the whole class, including the
+	constructor that I needed (CultureInfo (string)).
+
+	Updated fields after reading the new docs from the final SDK.
+
+	* ResXFileRef.cs, ResXResourceReader.cs: Removed. They are part of
+	Windows.Forms and require System.Xml, which we don't have access to.
+
+2002-01-13  Duncan Mak  <duncan@ximian.com>
+
+	* ResourceManager.cs: Added more MonoTODOs and cleaned up some 
+	indenting.
+
+2002-01-09  Duncan Mak  <duncan@ximian.com>
+
+	* ResourceManager.cs: Fixed the GetSatelliteContractVersion()
+	method. It was missing a cast before. Removed MonoTODO
+	attribute. ;-) It was tested by John Barnette, so this shouldn't break
+	the build.
+
+	* ResourceManager.cs: Removed MonoTODO attribute on GetString
+	(string), as I believe it's correct. However, GetString
+	(string, CultureInfo) is definitely broken, so I'm marking it with
+	MonoTODO there. I also added MonoTODO to IntenalGetResourceSet().
+
+2002-01-06  Duco Fijma <duco@lorentz.xs4all.nl>
+	* Finalizing IResourceReader and IResourceWriter interfaces: 
+          Added "new"-modifier to IResourceReader.GetEnumerator
+	* Fixed compilation issues in other *.cs, so that the 
+          System.Resources namespaces can be included in the corlib build.
+
+2002-01-05  Ravi Pratap  <ravi@ximian.com>
+
+	* ResourceManager.cs : MonoTODO attribute decoration.
+	
+Tue Dec 18 13:18:32 CET 2001 Paolo Molaro <lupus@ximian.com>
+
+	* *.cs: fixed some of the compilation issues: missing
+	using directives, typos.
+
+2001-12-11  Duncan Mak  <duncan@ximian.com>
+
+	* Checked in to CVS.
+
+2001-12-10  Duncan Mak  <duncan@ximian.com>
+
+	* ResourceManager.cs (GetNeutralResourcesLanguage):
+	(GetSatelliteContractVersion): Implemented.
+	
+2001-12-09  Duncan Mak  <duncan@ximian.com>
+
+	* ResXResourceReader.cs: Initial attempt.
+
+	* ResXFileRef.cs: Initial attempt.
+

+
+2001-11-27  Duncan Mak <duncan@ximian.com>
+
+	* ResourceSet.cs:

+2002-07-22  Tim Coleman <tim@timcoleman.com>

+	* ReflectionPermission.cs:

+	* EnvironmentPermission.cs:

+		bad place for an override keyword :(

+

+2002-07-22  Tim Coleman <tim@timcoleman.com>

+	* ReflectionPermission.cs:

+	* EnvironmentPermission.cs:

+		Stubbs added because these are referenced

+		in System.Web.

+

+2002-07-13  Jonathan Pryor  <jonpryor@vt.edu>

+	* ResourcePermissionBase.cs: Stubbed out

+	* ResourcePermissionBaseEntry.cs: Implemented.

+

+2002-03-12  Duncan Mak  <duncan@ximian.com>

+

+	* SiteIdentityPermissionAttribute.cs: 

+	* UIPermissionAttribute.cs: These should inherit from

+	CodeAccessSecurityAttribute, not IsolatedStoragePermissionAttribute.

+

+2002-02-17  Duncan Mak  <duncan@ximian.com>

+

+	* FileDialogPermissionAccess.cs: Add in namespace declaration, so

+	that this one little unique enum wouldn't show up in the System

+	namespace when we ildasm corlib.dll ;-) Oops, my bad.

+

+2002-02-13  Dan Lewis	<dihlewis@yahoo.co.uk>

+

+	* SecurityPermission.cs,

+	IsolatedStoragePermissionAttribute.cs: New files

+

+2002-01-23  Duncan Mak  <duncan@ximian.com>

+

+	* FileDialogPermissionAccess.cs: Add to CVS.

+

+2002-01-20  Duncan Mak  <duncan@ximian.com>

+

+	* *Attribute.cs: Implemented all the properties in the attributes

+	and removed the relevent MonoTODO attributes.

+

+	* *Attribute.cs: Fixed indentation.

+

+2002-01-18  Duncan Mak  <duncan@ximian.com>

+

+	* EnvironmentPermissionAttribute.cs: 

+	* FileDialogPermissionAttribute.cs: 

+	* FileIOPermissionAttribute.cs: 

+	* IsolatedStorageAttribute.cs: 

+	* IsolatedStorageFilePermissionAttribute.cs: 

+	* PermissionSetAttribute.cs:

+	* SiteIdentityPermissionAttribute.cs: 

+	* StrongNamePermissionAttribute.cs: 

+	* UIPermissionAttribute.cs: 

+	* UrlIdentityPermissionAttribute.cs: 

+	* ZoneIdentityPermissionAttribute.cs: New files. Stubbed out with MonoTODOs

+

+	* Note: These are all the Attributes in the

+	System.Security.Permissions namespace. The only missing one is

+	PublishIdentityPermissionAttribute.cs because we don't have

+	anything for the X509Certificate class.

+

+2002-01-14  Nick Drochak  <ndrochak@gol.com>

+

+	* FileIOPermission.cs: New file.  Implemented.

+

+2002-01-08  Nick Drochak  <ndrochak@gol.com>

+

+2002-07-13  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* StringBuilder.cs: updated comments. MaxCapacity always returns
+	Int32.MaxValue.
+
+2002-06-21  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* StringBuilder.cs: implemented AppendFormat methods using
+	String.Format. Thanks Paolo!
+
+	This makes xsp generate correct C# output in linux :-). I still need
+	to do more testing, though.
+
+Mon Jun 3 12:58:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* ASCIIEncoding.cs: fixed handling of 0 bytecount.
+
+2002-05-19  Martin Baulig  <martin@gnome.org>
+
+	* Encoder.cs (IConvEncoder.GetByteCount, IConvEncoder.GetBytes):
+	Added exception handling.
+
+	* Decoder.cs (IConvDecoder.GetCharCount, IConvDecoder.GetChars):
+	Added exception handling.
+
+2002/04/02  Nick Drochak <ndrochak@gol.com>
+
+	* StringBuilder.cs (Append): Removed obsolete overload.
+
+2002-03-21  Mike Kestner  <mkestner@speakeasy.net>
+
+	* ASCIIEncoding.cs : Fix off by one error in Get(Char|Byte)Count.
+
+Thu Mar 21 17:38:19 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* StringBuilder.cs: no need to intern the string returned by ToString().
+
+2002-03-17  Mike Kestner  <mkestner@speakeasy.net>
+
+	* ASCIIEncoding.cs: Implement all the overridden methods. No longer
+	  dependent on iconv icalls.
+	* Encoding.cs: Fix count bugs in GetBytes and GetChars. Add virtual
+	  to GetBytes.
+
+Wed Mar 13 00:26:29 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* StringBuilder.cs: make ToString() return a interned string, this
+	seems to be required to make switch on string work.
+
+Fri Mar 8 17:29:58 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* StringBuilder.cs: make Append(char) do the smart thing.
+
+2002-01-05  Ravi Pratap  <ravi@ximian.com>
+
+	* ASCIIEncoding.cs, Encoding.cs, UTF7Encoding.cs, 
+	UnicodeEncoding.cs: MonoTODO attribute marking.
+
+	* StringBuilder.cs : Ditto.
+	
+Wed Nov 14 17:05:22 CET 2001 Paolo Molaro <lupus@ximian.com>
+
+	* Encoding.cs: renamed some fields.
+	* StringBuilder.cs: CLSCompliant updates.
+
+2001-10-29  Nick Drochak  <ndrochak@gol.com>
+
+	* StringBuilder.cs: Throw exceptions when constructor paramter(s) are
+		invalid. Just like MS does (as best as I can tell).
+
+	Tests for these exceptions are now added to the unit tests as well.
+
+2001-10-25  Nick Drochak  <ndrochak@gol.com>
+
+	* StringBuilder.cs: Throw exception if they try to make a StringBuilder
+		whose capacity is greater than the MaxCapacity.
+
+	I added some tests for the constructors and the above exception. More
+	coming soon.
+
+2001-10-23  Nick Drochak  <ndrochak@gol.com>
+
+	* StringBuilder.cs: Refactored constructor code into just one
+	constructor. All the other construtors call it. Also supplied missing
+	constructors so the class has all those in the spec.
+
+	Added the MaxCapacity property as well, however this needs to be 
+	completed to return a value is related to the available system memory.
+
+2001-10-07  Miguel de Icaza  <miguel@ximian.com>
+
+	* Encoding.cs, UTF8Encoding.cs, UTF7Encoding.cs, ASCIIEncoding.cs,
+	UnicodeEncoding.cs: Corrected API.
+
+	* UTF8Encoding.cs: Checked in changes from Rafael.
+
+2001-08-28  Dietmar Maurer  <dietmar@ximian.com>
+
+	* UTF8Encoding.cs: impl. clumsy GetBytes
+
+2001-07-16  Marcin Szczepanski <marcins@zipworld.com.au>
+
+	* StringBuilder.cs (Text): Fixed.
+
+	* StringBuilderTest.cs: Implement Test suite.
+
+2001-07-12  Marcin Szczepanski <marcins@zipworld.com.au>
+
+	* StringBuilder.cs: Implemented.
+
+	The only methods left unimplemented are the AppendFormat( ... )
+	ones just because it's probably better to wait until some of the
+	Format related classes are implemented.  I've put that as a TODO
+	comment at the top and created the methods with a "nop" body.
+
+2001-06-26  Sean MacIsaac  <macisaac@ximian.com>
+
+	* UnicodeEncoding.cs: Members added so that a clean compile is
+	possible.
+
+	* ASCIIEncoding.cs: Members added so that a clean compile is
+	possible.
+
+	* UTF7Encoding.cs: Members added so that a clean compile is
+	possible.
+
+	* UTF8Encoding.cs: Members added so that a clean compile is
+	possible.
+
+	* Encoding.cs: All public members included.  Most members
+	unimplemented.

+2002-04-30  Dick Porter  <dick@ximian.com>
+
+	* Thread.cs: If LocalDataStoreSlot already has data set, remove it

+
+	Use the Thread object destructor to tell the runtime to close the
+	thread handle.
+
+2002-04-14 Patrik Torstensson <patrik.torstensson@labs2.com>
+
+	* Interlocked.cs: made all methods icalls.

+
+	* IOCompletionCallback.cs: added attributes to the delegate
+	(CLSCompliant(false) and Serializable).
+
+2002-04-14 Patrik Torstensson <patrik.torstensson@labs2.com>
+	* Thread.cs: Fixed IsThreadPoolThread to use a internal property instead of extending 
+				 the threadstate enum.
+	* ThreadPool.cs: Now using the internal Isthreadpoolthread property
+	* ThreadState.cs: removed non-standard enum (ThreadPoolThread)
+
+2002-04-14 Patrik Torstensson <patrik.torstensson@labs2.com>
+
+	* ThreadState.cs: Added enum for threadpool thread
+	* Thread.cs: changed the set/clr_state to be internal (used from threadpool)

+
+Wed Feb 13 21:51:30 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* Thread.cs: implement CurrentCulture property needed by
+	Convert.ChangeType() (used when compiling enums).
+
+2002-01-23  Dick Porter  <dick@ximian.com>
+
+	* ManualResetEvent.cs: 
+	* AutoResetEvent.cs: Fixed DOS line endings
+
+2002-01-22  Veronica De Santis <veron78@interfree.it>   
+        
+	* NativeEventCalls : Class that contains internal calls shared by Auto 
+	  		     and Manual Reset Events
+	* AutoResetEvents.cs : Added class AutoResetEvents and its implementation

+	* WaitHandle.cs : Renamed handle to os_handle and make it protected
+	                  instead of private.
+	* Mutex.cs : Write the System.Threading.Mutex methods ( constructors 
+	             and the ReleaseMutex)
+
+2002-01-15  Dick Porter  <dick@ximian.com>
+
+	* WaitHandle.cs:

+	internal calls using the new IO library, and the newly-supported
+	bool returns from internal calls.

+
+	* Int32.cs:
+	* Int64.cs:
+	* UInt32.cs:
+	* UInt64.cs: fixed bug #28050. May be a MS bug?
+
+Thu Jul 18 14:47:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* MonoType.cs: fix IsArrayImpl.
+
+2002-07-13  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* String.cs: make ToLower (culture) and ToUpper (culture) use the
+	default ToLower and ToUpper and don't throw NotImplemented.
+
+Sat Jul 13 15:09:01 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* Type.cs: make GettTypeCode an icall. Test implementation of
+	GetMember().
+
+2002-07-13  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* AppDomainSetup.cs: implemented LoaderOptimization.
+
+2002-07-10  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* Activator.cs: some more intermediate results checking in
+	in CreateInstance and CreateInstanceFrom and use GetConstructor and
+	Invoke only with Type [] until the other overloaded versions work.
+
+2002-07-09  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* Activator.cs: reformatted. Implemented CreateInstance* methods
+	that return ObjectHandle.
+
+	* AppDomain.cs: implemented CreateInstance*AndUnwrap methods.
+
+2002-07-03  Nick Drochak  <ndrochak@gol.com>
+
+	* Decimal.cs (Divide): Short cut the case where the dividend is 0 (and
+	the divisor is not) and avoid the icall, which seems to have a bug.
+
+2002-07-03  Nick Drochak  <ndrochak@gol.com>
+
+	* Double.cs (CompareTo): Correctly handle the case where the instance
+	is NaN. Also return 0 if the values are equal.
+
+2002/07/03  Nick Drochak <ndrochak@gol.com>
+
+	* MissingMethodException: Add missing Message property
+	* MissingMemberException: Add missing Message property
+
+2002-06-30  Nick Drochak  <ndrochak@gol.com>
+
+	* Double.cs (CompareTo): Just see which is bigger.  Don't use the
+	subtraction trick, it doesn't work when the values have a diference of
+	less than one.
+
+	* Single.cs (CompareTo): same
+
+2002-06-27  Martin Baulig  <martin@gnome.org>
+
+	* UIntPtr.cs (UIntPtr.Zero): Use an explicit `u' suffix in the
+	constructor argument.  [FIXME: The implicit conversion to an
+	unsigned integer doesn't work with mcs.]
+
+2002-06-26  Martin Baulig  <martin@gnome.org>
+
+	* DecimalFormatter.cs: Removed MSTEST stuff, use `System',
+	not `S = System'.  This file now compiles with mcs.
+
+	* String.cs: Removed the already ifdef-outed __arglist Concat function
+	to make it compile with mcs.
+
+2002-06-24  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* IntegerFormatter.cs:
+	(FormatParse.FormatNumber): fixed custom format for negative numbers.
+
+2002-06-21  Martin Baulig  <martin@gnome.org>
+
+	* Double.cs: Replace the private `enum State' with constants since this
+	will avoid some bigger headaches in mcs.
+
+Thu Jun 20 17:51:44 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* TimeSpan.cs: do not pollute the namespace with the
+	System.Parser name.
+
+2002-06-18  Nick Drochak  <ndrochak@gol.com>
+
+	* ArgumentException.cs: Use the message given in the constructor when
+	accessing the Message property.  Thanks to Dietmar for the help with 
+	"base".
+
+2002-06-17  Dietmar Maurer  <dietmar@ximian.com>
+
+	* MonoType.cs: GetField is now a InternalCall
+
+2002-06-13  Nick Drochak  <ndrochak@gol.com>
+
+	* DateTime.cs: (Parse): Accept dates that have no hour,min,sec. in the
+	sortable format(s), e.g. "2002-02-25"
+
+2002/06/12  Nick Drochak <ndrochak@gol.com>
+
+	* Random.cs (Next): Fix math error.  Return a number within the range.
+
+2002-06-12  Nick Drochak  <ndrochak@gol.com>
+
+	* String.cs (IndexOf): Return -1 if start index is equal to string
+	length.
+
+2002-06-10  Duncan Mak  <duncan@ximian.com>
+
+	* Convert.cs (ToDouble): Remove rounding in ToDouble (float).
+	(ToType): Added null field in conversionTable to avoid

+	
+2002-06-11  Nick Drochak  <ndrochak@gol.com>
+
+	* Int64.cs (Parse): Added unique strings to the messages where we throw
+	a FormatException. Needed these to debug, so just left them in since
+	they might be useful later. Fixed Currency parsing where we weren't
+	looking at CurrencyDecimalSeparator, etc.
+
+2002-06-09  Lawrence Pit  <loz@cable.a2000.nl>

+

+	* DateTime.cs: fixes to pass tests M0 to M6:

+		if yy pattern then year values >= 30 are in 20th century

+		rfc1123 pattern is always in GMT, therefor useutc must be false

+	made GetNow() internal static so it can be called from TimeZone.

+	* TimeZone.cs: removed dependency on year 2002 from initialization of 

+	current timezone.

+

+2002-06-09  Duncan Mak  <duncan@ximian.com>

+
+2002-06-08  Martin Baulig  <martin@gnome.org>
+
+	* Enum.cs (IsDefined): `value' may be of the enum's type itself, it
+	doesn't necessarily need to be of the enum's underlying type.
+
+2002/06/07  Nick Drochak <ndrochak@gol.com>
+
+	* String.cs: Add [Serializable] to class

+
+2002-06-04  Nick Drochak  <ndrochak@gol.com>
+
+	* Double.cs (Parse): Recognize the group separator string, but still we
+	don't check the format for the proper number of digits between
+	separators. Also throw OverflowException when we get Pos or Neg
+	Infinity from runtime.
+
+2002-06-03  Duncan Mak  <duncan@ximian.com>
+
+	* Convert.cs (ToDouble): Fixed ToDouble (byte value).
+
+Mon Jun 3 12:18:18 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* Type.cs: fixed GetTypeCode.
+
+2002-06-02  Duncan Mak  <duncan@ximian.com>
+
+	* Convert.cs (ToInt16): use Convert.ToInt16 (int) instead of a direct
+	cast from an int so that we throw OverFlowException correctly.
+	
+	(ToInt64): Use a new 64bit version of ConvertToBase.
+	
+	(ConvertToBase): Add checks for overflow (checks Int32.MinValue
+	and Int32.MaxValue).
+
+	(ConvertFromBase64): New 64-bit version of ConvertFromBase.
+
+2002-06-02  Nick Drochak  <ndrochak@gol.com>

+
+2002-06-02  Duncan Mak  <duncan@ximian.com>
+
+	* Convert.cs (DBNull): Point it to DBNull.Value.
+	(IsDBNull): Instead of checking typecodes, just check to see if
+	it's the same as the DBNull field.
+
+2002-06-02  Nick Drochak  <ndrochak@gol.com>
+
+	* Convert.cs (ConvertFromBase): Detect bad digits correctly.
+
+2002-06-02  Duncan Mak  <duncan@ximian.com>
+

+
+	* Convert.cs (ToType): Rearranged to fit the new layout of
+	conversionTable.
+
+	(conversionTable): Rearranged to fit the layout of the
+	System.TypeCode enum.
+
+	This should fix bug 25075.
+	
+2002-05-21  Duncan Mak  <duncan@ximian.com>
+
+	* Convert.cs (ToString): Fixed the ToString methods. Previously I had
+	mixed up the two code paths, one for converting to a specific base
+	(this case), another from converting from a foreign base to base10
+	(used by ToInt16|32|64 (string, int)). This fixes bug 25068.
+
+	* Convert.cs (ToByte)
+	(ToSByte): Fixed bug 25074. Added more bits to ConvertFromBase so
+	that we won't confuse FormatException with OverflowException.
+
+2002-05-22  Lawrence Pit  <loz@cable.a2000.nl>
+
+	* Environment.cs: CommandLine missed spaces between arguments.
+	Implemented StackTrace. Returning MachineName in UserDomainName

+	and then passing to strtof in the mono runtime.
+

+	float. 
+
+2002-05-21  Nick Drochak  <ndrochak@gol.com>

+
+2002-05-19  Martin Baulig  <martin@gnome.org>

+
+2002-05-14  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* ChangeLog: removed empty entry at the top of the file.
+
+	* Int32.cs: made static functions used by Parse internal.
+

+2002-05-12  Daniel Morgan <danmorg@sc.rr.com>
+
+	* IServiceProvider.cs: added using System
+
+2002-05-09  Daniel Morgan <danmorg@sc.rr.com>
+
+	* Single.cs: copied ToString() and Parse() methods from 
+	Double to Single and modified a tiny bit for Single.  
+	There is still a FIXME for Double and Single about
+	passing the format and provider info to the icall too.

+
+2002-05-02  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* Int32.cs:
+	* Int64.cs:
+	* UInt32.cs:

+
+2002-04-27  Nick Drochak  <ndrochak@gol.com>

+	MS.NET does.
+
+2002-04-26  Duncan Mak  <duncan@ximian.com>
+
+	* MissingMemberException.cs: Made the message variable 'protected'
+	instead of 'private', so that we can see it in

+	buf fix in Concat.
+
+Thu Apr 18 17:16:15 CEST 2002 Paolo Molaro <lupus@ximian.com>

+
+Thu Apr 18 12:38:32 CEST 2002 Paolo Molaro <lupus@ximian.com>

+
+	* Int32.cs:
+	* UInt32.cs:

+	* UInt64.cs: fixed error when testing for validity of flags.
+
+2002-04-11  Nick Drochak  <ndrochak@gol.com>
+
+	* Double.cs: Use an internal call for ToString(). This is just a simple
+	implementation to get away from throwing a NotImplementedException.
+
+2002-04-10  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* Int32.cs:
+	* UInt32.cs:

+	string.
+
+2002-04-09  Nick Drochak  <ndrochak@gol.com>
+
+	* IntegerFormatter.cs: Don't use a format character to indicate a
+	custom format was passed in. It was using 'z' to indicate a custom
+	format, but really it should throw a format exception if the user
+	tries to use "z" as the format string. Now it does.
+
+	* Activator.cs: New File.
+
+2002-04-08  Nick Drochak  <ndrochak@gol.com>
+
+	* Enum.cs (ToString): Big ugly fix for the case where [Flags] is
+	applied to an enum. Need to handle the different possible integer
+	types of an enum somehow.  Can anyone say generics?
+
+Mon Apr  8 06:22:42  2002 Piers Haken <piersh@friskit.com>
+
+	* Convert.cs: switched the To*(object) methods to use

+
+	* ValueType.cs: make Equals() an internalcall.
+

+
+2002-04-05  Nick Drochak  <ndrochak@gol.com>
+
+	* Enum.cs (Parse): Handle different underlying types.
+
+2002/04/04 Nick Drochak <ndrochak@gol.com>
+
+	* Enum.cs (IsDefined): Throw exception when type of value to look for
+	is not the correct one.  Attempt to have it work with string values
+	too, but not sure if the unit tests are getting that far yet.
+
+2002-04-04  Nick Drochak  <ndrochak@gol.com>
+
+	* Decimal.cs: Fix a couple of typos.
+
+Wed Apr 3 19:46:00 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* Enum.cs: the values array is of the enum and not of the underlying
+	type. Updates and some bug fixes.
+	* MonoType.cs: make the internalcall return FullName instead of the
+	assembly qualified name.
+	* Type.cs: make ToString () simply return FullName.
+
+2002-04-03  Nick Drochak  <ndrochak@gol.com>
+
+	* Type.cs (GetTypeCode): provide some of the implementation for this
+	method.  It's still too simplistic to be considered complete.
+
+2002-04-02  Dietmar Maurer  <dietmar@ximian.com>
+
+	* Object.cs: fixed FieldGetter/FieldSetter signature
+
+2002-04-02  Nick Drochak  <ndrochak@gol.com>

+	* Environment.cs: add MonoTODO's on parts that should have it.
+
+2002-04-01  Nick Drochak  <ndrochak@gol.com>
+
+	* Enum.cs: added reality checks (check parameters to most methods that

+
+2002-03-30  Dietmar Maurer  <dietmar@ximian.com>
+
+	* Object.cs: added FieldGetter/FieldSetter
+
+2002-03-28  Gonzalo Paniagua Javier <gonzalo@ximian.com>

+
+2002-03-28  Gonzalo Paniagua Javier <gonzalo@ximian.com>

+2002/03/28  Nick Drochak <ndrochak@gol.com>
+
+	* IntegerFormatter.cs: Change class from internal to public.  Add

+
+2002-03-27  Dan Lewis  <dihlewis@yahoo.co.uk>

+	* Environment.cs: removed PAL dependencies.
+
+2002-03-25  Miguel de Icaza  <miguel@ximian.com>
+
+	* String.cs (System): Removed internal enumeration, because
+	bootstrapping the corlib at this point does not support
+	enumerations. 
+
+	* IntPtr.cs: Temporary work-around until I fix the assembly
+	attributes bug.
+
+2002-03-24  Martin Baulig  <martin@gnome.org>
+
+	* Enum.cs (GetValues): According to the docu this is sorted after
+	values, not names.
+
+	* String.cs (System): Removed enumeration, because it is pretty
+	hard to support enumerations in /nostdlib mode for the core types.
+
+Tue Mar 19 18:18:49 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* Array.cs: move error handling in the catch block.
+	* MulticastDelegate.cs: remove == and != operators that were
+	removed with the delegate changes (when you add stuff, please do not
+	remove existing functionality!).

+	in the parent types, too.
+
+2002-03-18  Dan Lewis <dihlewis@yahoo.co.uk>
+	
+	* Math.cs: changed to use icall instead of PAL.

+	* Double.cs: added check for NaN (Bug [22082])
+
+2002-03-19  Nick Drochak  <ndrochak@gol.com>
+
+	* Enum.cs (Equals): check for null and throw if it is.
+	* Enum.cs (Format): check for null parameters and throw if necessary.
+	This method still needs more argument checking.
+
+2002-03-18  Dietmar Maurer  <dietmar@ximian.com>
+
+	* Enum.cs (Equals): check if Enums are of the same type
+
+2002-03-18  Nick Drochak  <ndrochak@gol.com>
+
+	* Double.cs: Explicitly handle comparisons in CompareTo() for
+	Positive/Negative Infinity and NaN. Unit Test now passes on Linux.
+
+	* Enum.cs(CompareTo): Check types of values before trying to compare.
+	Throw exceptions if types are invalid or don't match.
+
+2002-03-14  Miguel de Icaza  <miguel@ximian.com>
+
+	* Array.cs: Add some extra debugging information.
+
+2002-03-15  Nick Drochak  <ndrochak@gol.com>

+	NonCLSCompliant. 
+
+2002-03-14  Dietmar Maurer  <dietmar@ximian.com>
+
+	* Delegate.cs (Equals): also compare method_ptr 
+	(GetHashCode): returm method_ptr as hash
+
+2002-03-13  Duco Fijma  <duco@lorentz.xs4all.n>
+	* TimeSpan.cs: removed the use of Custom Numeric Format Strings,
+	such as 42.ToString("0000000"), as these are (currently) not implemented
+	in System.IntegerFormatter. TimeSpan luckely can do with Standard
+	Numeric Format Strings, such as 42.ToString("D7").
+
+2002-03-12  Duncan Mak  <duncan@ximian.com>
+
+	* FieldAccessException.cs: 
+	* MethodAccessException.cs: 
+	* PlatformNotSupportedException.cs: Inherit from
+	MemberAccessException, not SystemException.
+
+	* ObsoleteAttribute.cs: Made Message and IsError properties
+	instead of fields.
+
+Tue Mar 12 19:21:18 CET 2002 Paolo Molaro <lupus@ximian.com>

+	runtime that goes with this patch.
+
+2002-03-10  Martin Baulig  <martin@gnome.org>
+

+
+2002-03-08  Martin Baulig  <martin@gnome.org>
+
+	* String.cs (Split): Really fix it this time. Also adding several new
+	testcase to the testsuite.	 
+
+2002-03-08  Martin Baulig  <martin@gnome.org>
+
+	* Array.cs (Copy): Optimized: removed duplicate null check, removed
+	two duplicate GetLowerBound() calls and one duplicate IsValueType.
+
+Fri Mar 8 18:49:19 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* Object.cs: commit my hacked GetHashCode(): it's good enough for now.
+	* String.cs: use the dumb code for IndexOf(string): this is worth
+	15-20 % speedup in mcs compile with mint.
+
+Fri Mar 8 12:45:44 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* String.cs: revert change to Split() that broke the compiler (hi martin!:-).
+
+2002-03-07  Martin Baulig  <martin@gnome.org>
+
+	* String.cs (Join): Throw an ArgumentNullException.
+	(LastIndexOf (string,int,int)): This method does a backwards search,
+	so startIndex points to the end of value, not to its beginning. Don't
+	throw an exception if startIndex equals this.Length. Always return -1
+	if startIndex is smaller than the length of value.
+	(Replace (string,string)): Replace all occurences of oldValue.
+	If newValue is null, all occurences of oldValue are to be removed.
+	(Split (char[],int)): Return an empty array if maxCount is zero, throw
+	an ArgumentOutOfRangeException if it's less than zero. Return maxValue
+	elements, not maxValue+1.
+
+Thu Mar 7 17:16:06 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* MonoType.cs: make GetEvents() an internal call.
+	* MulticastDelegate.cs: copy the passed in array.
+
+2002-03-06  Martin Baulig  <martin@gnome.org>
+
+	* Array.cs (Copy): Use FastCopy when appropriate and do correct
+	exception handling.
+
+2002-03-06  Duco Fijma  <duco@lorentz.xs4all.nl>
+	* CharEnumerator.cs: fixes to CharEnumertor.MoveNext, fixing 
+	some of the failures found be new tests (see ChangeLog in 
+	Test/System). Comments added to this method, based on
+	the representation invariant of this class, that (try to) explain
+	why it now should be correct.
+
+2002-03-06  Dietmar Maurer  <dietmar@ximian.com>
+
+	* Int64.cs (Parse): bug fix for max. negative value. 
+
+2002-03-07  Nick Drochak  <ndrochak@gol.com>
+
+	* RuntimeTypeHandle.cs: Add Serializable attribute as the docs say.
+	I need to understand what the difference between the attribute and
+	the interface is.
+
+2002-03-06  Martin Baulig  <martin@gnome.org>
+
+	* Array.cs (Copy): Always throw an ArrayTypeMismatchException, not
+	an InvalidCastException if the widening conversion failed. See
+	testcases #M94-#M96.
+
+	* Array.cs (CopyTo): Bug fix from Ajay Dwivedi, correctly handle
+	arrays with non-zero lower bounds. Also adding testcases #F10-#F13
+	for this.
+
+	* Array.cs (CopyTo): Reverted my last change, it was incorrect.
+	(Copy): Actually allow copying multi-dimensional arrays.
+
+2002-03-05  Duncan Mak  <duncan@ximian.com>
+
+	* Convert.cs:
+	(DBNull) Added the missing field.
+	(IsDBNull) Fixed typo.
+	(ToByte (string, int)) Implemented.
+	(ToString (byte, int)) Implemented.
+	(ConvertToBase)
+	(BuildConvertedString) internal functions used for converting values to
+	a specific base.
+
+	* Int16.cs: 
+	* Int32.cs:
+	* Int64.cs:
+	* Single.cs:
+	* UInt16.cs: 
+	* UInt32.cs: Implemented the IConvertible interface.	
+
+	* CharEnumerator.cs: Renamed to variables to be clearer and
+	changed some of the tests to conform to the 1.0 spec.
+
+2002-03-06  Martin Baulig  <martin@gnome.org>
+
+	* Array.cs (Copy): Calculate absolute array position here and use
+	GetValueImpl() and SetValueImpl() with that position. We can now
+	copy multi-dimensional arrays.
+	(CopyTo): Small bug fix.
+
+2002-03-05  Duco Fijma  <duco@lorentz.xs4all.nl>
+
+	* Version.cs: CompareTo changed according the LAMESPEC discovered by 
+	Nick (See VersionTest.cs).
+	* CharEnumerator.cs: fixed two bugs in MoveNext. It had an off-by-one
+	error comparing the current position (idx) against the length of the
+	string iterated and it set idx to an unrecognized special value (-2)
+
+Tue Mar 5 17:34:14 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* SByte.cs, UInt64.cs: implement IConvertible interface. Nobody wants
+	to do this dirty work, but someone has to do it (and I need it to pass
+	the "200 sample tests compiled on linux" mark).
+
+2002-03-06  Nick Drochak  <ndrochak@gol.com>
+
+	* Attribute.cs
+	* DecimalFormatter.cs
+	* Delegate.cs
+	* Double.cs
+	* GC.cs
+	* Int16.cs
+	* Int32.cs
+	* MonoType.cs
+	* RuntimeMethodHandle.cs
+	* RuntimeTypeHandle.cs
+	* String.cs
+	* Type.cs:
+		Add [MonoTODO]'s to places where we currently throw a
+		NotImplementedException.
+
+2002-03-05  Dietmar Maurer  <dietmar@ximian.com>

+	checking.
+
+2002-03-04  Duco Fijma  <duco@lorentz.xs4all.nl>
+	* Version.cs: many fixes to failures found by the newly created
+	test cases for this class. Specifically, the CompareTo member
+	returned wrong values due to the use of Int32.MaxValue as a special
+	value indicating an "undefined" version component. Also implemented the
+	missing operators (==, <, >, etc.), one missing constructor and
+	and some exception throwing.
+
+2002-03-04  Nick Drochak  <ndrochak@gol.com>
+
+	* IServiceProvider.cs: Add missing attribute: ComVisible(false)
+	* Attribute.cs: Add missing attributes: Serializable and
+	AttributeUsage(AttributeTargets.All)

+
+	* MonoType.cs: implemented GetConstructors(), GetFields(),
+	GetMethods(), GetProperties().
+	* Object.cs: added debugging icall obj_address().
+	* Type.cs: fixed the binding flags for some Get* methods.
+	Implemented FindMembers() as calls to the specific GetMember
+	methods.
+
+2002-03-01  Duco Fijma  <duco@lorentz.xs4all.nl>
+	* BitConverter.cs: fixed one little bug: ToString(s, n, 0) 
+	should give an exception for n>=s.Length.
+
+2002-03-01  Martin Baulig  <martin@gnome.org>
+
+	* Array.cs: More argument checking and bug fixing.
+
+2002-03-01  Miguel de Icaza  <miguel@ximian.com>
+

+
+	* AppDomain.cs: Added MonoTODOs to this too.
+

+
+Fri Mar 1 15:20:00 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* MulticastDelegate.cs: implement operators so mcs3 can be used on linux.
+
+2002-03-01  Nick Drochak  <ndrochak@gol.com>
+
+	* BitConverter.cs: Throw ArgumentException like mscorlib, instead of
+	ArgumentOutOfRangeException like the docs say.
+
+2002-03-01  Martin Baulig  <martin@gnome.org>
+
+	* Enum.cs (CompareTo): Correctly override this method from IComparable.
+
+	* Console.cs (setIn, setOut, setError): It's called SetIn, SetOut, SetError.
+
+2002-02-28  Martin Baulig  <martin@gnome.org>
+
+	* String.cs: This file now passes the testsuite on Linux :-)
+	
+	* String.cs (Intern, IsInterned): The interncalls are now called _Intern and _IsInterned;
+	make them private and provide C# wrappers which do proper argument checking.
+
+	* String.cs (Format): Correctly handle escaped brackets.
+
+	* String.cs (_CompareChar): New internal function which compares two chars.
+	(_Compare): Provide an internal compare method which can do all sorts of
+	comparision and call it from all the Compare() methods. Also fixed a lot of
+	bugs here, this code now actually passes the testsuite.
+
+2002-02-28  Duncan Mak  <duncan@ximian.com>
+
+	* Convert.cs: Added the missing methods. The new class status page
+	kicks ass, it even found my typos! Woohoo!
+	(ConvertFromBase): Moved the Exception throwing in here and
+	removed the other occurances so it's all centralized now.
+	(ISDBNull): Implemented.
+	(GetTypeCode): Implemented.
+
+2002-02-27  Duco Fijma  <duco@lorentz.xs4all.nl>
+	* Guid.cs: Guid.ToString("") and Guid.ToString(null) is now understood as Guid.ToString("D") 
+	just as in mscorlib. There is (probably) a documentation bug in the MS FrameWork SDK, which
+        states that a lacking format should be interpreted as "N".  
+	Also added [Serializable] attribute
+	* TimeSpan.cs: some formatting and added the [Serializable] attribute
+
+2002-02-26  Duncan Mak  <duncan@ximian.com>
+
+	* WeakReference.cs: Committed for Ajay Kumar Dwivedi.	
+
+2002-02-26  Martin Baulig  <martin@gnome.org>
+
+	* TimeZone.cs: Use an internal enum rather than magic numbers to access the
+	fields of the interncall GetTimeZoneData.
+
+	* DateTime.cs: Implemented Parse and fixed a few bugs.
+
+	* String.cs (TrimStart): Small fix.
+
+2002-02-26  Martin Baulig  <martin@gnome.org>
+
+	* DateTime.cs: ParseExact is now fully functional.
+
+	* String.cs (TrimEnd): Small fix.
+
+2002-02-26  Duco Fijma <duco@lorentz.xs4all.nl>
+	* TimeSpan.cs: Added method TimeSpan.FromMilliseconds, mysteriously 
+	missing for about six months.
+
+Tue Feb 26 14:21:19 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* UInt64.cs: fixed Parse method () to handle some of the NumberStyle flags.
+
+2002-02-26  Martin Baulig  <martin@gnome.org>
+
+	* DateTime.cs: Miguel already committed this, but there was still a
+	ChangeLog entry for this missing ....
+	We're now reusing functionality from TimeSpan, printing dates is
+	fully implemented, currently working on parsing.
+
+	* TimeZone.cs: Fully implemented this. There's a new InternCall in the
+	runtime for this.
+
+Fri Feb 22 18:47:08 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* MonoType.cs: disable constructor.
+	* Object.cs: make GetType() an internalcall.
+	* Type.cs: added correct bindingflags to GetMethods ().
+	All such calls should be reviewed to use the correct flags.
+
+Thu Feb 21 19:23:46 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* Type.cs, MonoType.cs: type_is_subtype_of () changed to include extra
+	argument.
+
+Thu Feb 21 16:56:51 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* Type.cs: implemented IsAssignableFrom.
+
+2002-02-21  Duco Fijma <duco@lorentz.xs4all.nl>

+	"{0xdddddddd,0xdddd,0xdddd,{0xdd},{0xdd},{0xdd},{0xdd},{0xdd},{0xdd}}" 
+	to "{0xdddddddd,0xdddd,0xdddd,{0xdd,0xdd,0xdd,0xdd,0xdd,0xdd}}" 
+	The former is documented by Microsoft. The latter is how they
+	actually implemented it in mscorlib:-)
+

+
+	* MonoCustomAttrs.cs: hooks to get the custom attributes from the
+	runtime.

+	new private method ConvertFromBase.

+2002-02-19  Dietmar Maurer  <dietmar@ximian.com>
+
+	* String.cs: impl. IConvertible interface
+

+2002-02-18  Duncan Mak  <duncan@ximian.com>
+
+        * Convert.cs: Changed from using Type.GetType (string) to just
+        typeof (). Probably will speed things up a bit?		
+
+2002-02-18  Ajay Kumar Dwivedi <AjayKumar.Dwivedi@dresdner-bank.com>
+
+	* Array.cs:         
+	1. Fix for GetUpperBound to return correct values
+        2. made some Properties virtual
+        3. Adds IsFixedSize and IsReadOnly properties.
+        4. changes CreateInstance(Type,int[],int[]) to throw Exception

+
+2002-02-17  Duncan Mak  <duncan@ximian.com>
+
+        * TimeZone.cs:	Applied the rest of Ajay's patch for	
+        IsDaylightSavingTime. Thanks a lot for the nice explanation of how
+        it works!
+
+2002-02-17  Duco Fijma  <duco@lorentz.xs4all.nl>
+	* Guid.cs: added stub for Guid(string) ctor
+
+2002-02-17  Duncan Mak  <duncan@ximian.com>
+
+	* Convert.cs: Near-complete implementation of Convert.cs

+	(object, IFormatProvider) as parameters.
+
+	Added [CLSCompliant (false)] attributes to methods dealing with
+	unsigned types.
+
+	Added the missing section on converting to and from DateTime. Only
+	6 missing methods, all marked with MonoTODOs. Will tackle them later.		
+
+2002-02-16  Duncan Mak  <duncan@ximian.com>
+
+	* TimeZone.cs: patch from Ajay Kumar Dwivedi (adwiv@yahoo.com) to
+	make IsDaylightSavingTime (DateTime) call

+
+Fri Feb 8 18:06:20 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* MarshalByRefObject.cs: add ToString () method
+	(apparently needed by nunit).
+	* _AppDomain.cs: uncomment ToString(): dietmar fixed the bug triggered
+	by it in the runtime.
+
+2002-02-08  Dan Lewis <dihlewis@yahoo.co.uk>
+	
+	* String.cs (Format): implemented
+
+2002-02-07  Duncan Mak  <duncan@ximian.com>

+
+	* Enum.cs (Parse,  GetHashCode): impl. 
+
+2002-02-05  Duncan Mak  <duncan@ximian.com>
+
+	* DBNull.cs: This is my first crack at the DBNull class. I think I
+	actually got most of the IConvertible methods right, but I haven't
+	done the research to test whether or not this is the correct
+	behavior. IConvertible.ToType () is the most iffy of all, IMHO.
+
+	* DllNotFoundException.cs: Inherits from TypeLoadException, not SystemException.
+
+2002-02-05  Dietmar Maurer  <dietmar@ximian.com>
+

+
+Tue Jan 29 22:32:36 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* _AppDomain.cs: remove ToString() method: it doesn't seem right 
+	to have it in this interface and it screws up the method vtable setup.
+
+2002-01-28  Andrei Zmievski <andrei@php.net>
+
+	* Double.cs: implemented IConvertible interface.
+
+2002-01-28  Miguel de Icaza  <miguel@ximian.com>

+	(AppDomain.AppDomain): Prime the loaded assemblies with the
+	assemblies loaded by the runtime in our behalf.
+
+	* AppDomainSetup.cs: Remove private keyword, that is the default.
+	Add a new property DisallowPublisherPolicy.
+
+	* AppDomain.cs (AppDomain.GetAssemblies): Implement.
+
+Tue Jan 22 22:51:48 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* MonoType.cs, Type.cs: many updates, corrected implementation,
+	completed stubs.
+
+2002-01-20  Andrei Zmievski <andrei@php.net>
+
+	* Byte.cs:
+	* Char.cs: implemented IConvertible interface.
+
+	* Boolean.cs: use our own ToString() method directly.
+
+2002-01-20  Duncan Mak  <duncan@ximian.com>
+
+	* Files I commited recently: Fixed indentation style.
+
+2002-01-20 Nick Drochak  <ndrochak@gol.com>

+
+2001-08-02  Marcel Narings  <marcel@narings.nl>
+	
+	* DateTime.cs: Cleaned up a bit. Added the Add* family members.
+	Added exceptions. Added IConvertible. Still needs some platform 
+	dependend stuff, the Parse and ToString members
+
+2001-08-01  Dietmar Maurer  <dietmar@ximian.com>
+
+	* Type.cs (GetTypeFromHandle): added placeholder 
+
+2001-07-24  Derek Holden  <dholden@draper.com>
+
+	* Boolean.cs: Formatted to code style standard. Added GetTypeCode

+
+	* Byte.cs: Added a missing Parse method. Put in Parse and ToString
+	behavior, still need to do the main Parse and ToString.
+
+	* Char.cs: Added a bunch of missing ECMA methods. Commented a
+	specification discrepency. Still didn't any unicode stuff, though

+
+2001-07-18  Michael Lambert <michaellambert@email.com>
+
+        * AttributeTargets.cs: Add.
+
+2001-07-19  Jeffrey Stedfast  <fejj@ximian.com>
+
+	* Char.cs: Made ToUpper and ToLower public methods.
+
+	* String.cs: Lots and lots of compile fixes - just need to write
+	DateTime.cs and this should build completely now.
+
+2001-07-19  Bob Smith (bob@thestuff.net)
+
+	* Math.cs: Implemented. 
+
+2001-07-19  Miguel de Icaza  <miguel@ximian.com>
+
+	* String.cs: Removed tolower and toupper.
+
+	* Char.cs: Moved ToLower and ToUpper from string to here. 
+
+	* Convert.cs ToByte (float value), ToByte (double value) Use IsNan
+	instead of comparing the value to Nan.
+
+2001-07-19  Duco Fijma (duco@lorentz.xs4all.nl)
+
+	* TimeSpan.cs: New implementation.
+
+2001-07-18  Scott Sanders <scott@stonecobra.com>
+
+         * UriFormatExcpetion.cs: Add - 85% complete
+
+2001-07-17  Jeffrey Stedfast  <fejj@ximian.com>
+
+	* String.cs (IndexOf): Slight optimization that allows skipping
+	over a few chars here and there. This isn't as good as using my
+	Boyer-Moore implementation, however, Boyer-Moore is only really
+	good for long strings (I plan on making the code decide which
+	string search algorithm it should use on-the-fly at some point).
+	(LastIndexOf): Fix to work correctly.
+	(BoyerMoore): Took out some unneeded code and fixed an edge-case.
+
+2001-07-16  Michael Lambert <michaellambert@email.com>
+
+	* EventArgs.cs: Add.
+	
+2001-07-16  Miguel de Icaza  <miguel@ximian.com>
+
+	* Version.cs: Remove my buggy comment.
+
+2001-07-15  Sean MacIsaac  <macisaac@ximian.com>
+
+	* String.cs: Spelling error of IComparable, object's
+	MemberwiseClone cannot be overridden.  Made indexer valid for now,
+	but not sure what to do about this in the long run.  Seems to be a
+	couple bugs in csc.exe having to do with multiple pointer defs in
+	the same statement, and returning subclasses of a class in the
+	return type of an interface function implementation.  Also moved
+	operators inside of class definition.
+
+2001-07-14  Jeffrey Stedfast  <fejj@ximian.com>
+
+	* String.cs: A tom of compile fixes, although we still don't compile.
+
+	* IConvertible.cs: The To*Int64() methods return *Int64's, not
+	*Int32's. Also, it's ToDateTime() not ToDateType().
+
+2001-07-14  Jeffrey Stedfast  <fejj@ximian.com>
+
+	* String.cs: Apparently I needed to at least write stubs for the
+	IConvertible interfaces. *sigh*
+
+2001-07-14  Jeffrey Stedfast  <fejj@ximian.com>
+
+	* String.cs: Many logic/other fixes and better usage of the
+	features of c#
+	(tolower): New convenience method to help condense code.
+	(toupper): Another new helper method.
+	(Compare): Use the new helper methods.
+	(ToLower): use tolower().
+	(ToUpper): use toupper().
+	(LastIndexOfAny): Implemented.
+	(BoyerMoore): New private helper method that implements a modified
+	version of the Boyer-Moore search algorithm. Noothing uses it yet
+	as I'm not 100% sure it even works properly with unicode strings
+	not to mention it uses a huge lookup-table :-)
+	(Split): Implemented.
+
+2001-07-13  Jeffrey Stedfast  <fejj@ximian.com>
+
+	* TODO: Added things that need to be finished in System.String
+
+	* String.cs: New source file implementing the System.String class
+
+2001-07-12  Sean MacIsaac  <macisaac@ximian.com>
+
+	* TypeCode.cs: UInt64 was UInt63.
+
+	* Object.cs: Fixed a numer of compiler errors.
+
+	* Array.cs: Fixed some compiler errors.
+
+	* IComparable.cs: Fixed some compiler errors.
+

+	error.
+
+	* ApplicationException.cs: Removed a ; that was causing a compiler
+	error.

+
+2001-07-12  Joe Shaw  <joe@ximian.com>
+
+	* Array.cs: Fix backwards parameters to Array.SetValue()
+	throughout.
+	(BinarySearch): Fix backward logic surrounding whether to call
+	value.CompareTo or comparer.Compare.
+	(LastIndexOf): Stop being stupid. I am so not used to strongly
+	bounded arrays...
+	(Sort): Implement a quicksort.
+
+2001-07-11  Joe Shaw  <joe@ximian.com>
+
+	* Array.cs: Change all instances of trying to access an array with
+	the index operator to calls to GetValue and SetValue, and add
+	InternalGetValue and InternalSetValue which are internal calls
+	into the runtime. Ew.
+
+2001-07-10  Joe Shaw  <joe@ximian.com>
+
+	* Array.cs: Implemented everything but Sort().
+
+2001-07-09  Jeffrey Stedfast  <fejj@ximian.com>
+
+	* Object.cs (Object::Equals): Object variable name is `o'.
+
+2001-07-06  Joe Shaw  <joe@ximian.com>
+
+	* Int16.cs, Int32.cs, Int64.cs, UInt16.cs, UInt32.cs, UInt64.cs:
+	Implement the IComparable and IFormattable interfaces. Fix a typo
+	(publig -> public)
+
+	* ApplicationException.cs, ArgumentException.cs,
+	ArgumentNullException.cs, ArgumentOutOfRangeException.cs,
+	ArtithmeticException.cs, ArrayTypeMismatchException.cs,
+	DivideByZeroException.cs, DuplicateWaitObjectException.cs,
+	ExecutionEngineException.cs, FormatException.cs,

+
+2001-07-06  Miguel de Icaza  <miguel@ximian.com>
+
+	* Int64.cs, Int32.cs: Put.  Parsing and ToString missing.  Should
+	do a generic routine all of these guys use.
+
+	* Int16.cs: identified missing methods.
+
+	* UInt16.cs, UInt32.cs, UInt64.cs: Add.
+
+2001-06-26  Miguel de Icaza  <miguel@ximian.com>
+

+// System.Convert class. This was written word for word off the 

+// Library specification for System.Convert in the ECMA TC39 TG2 

+// and TG3 working documents. The first page of which has a table

+// for all legal conversion scenerios.

+//

+// This header and the one above it can be formatted however, just trying

+// to keep it consistent w/ the existing mcs headers.

+//

+// This Convert class could be written another way, with each type 

+// implementing IConvertible and defining their own conversion functions,

+// and this class just calling the type's implementation. Or, they can 

+// be defined here and the implementing type can use these functions when 

+// defining their IConvertible interface. Byte's ToBoolean() calls 

+// Convert.ToBoolean(byte), or Convert.ToBoolean(byte) calls 

+// byte.ToBoolean(). The first case is what is done here.

+//

+// See http://lists.ximian.com/archives/public/mono-list/2001-July/000525.html

+//

+// There are also conversion functions that are not defined in

+// the ECMA draft, such as there is no bool ToBoolean(DateTime value), 

+// and placing that somewhere won't compile w/ this Convert since the

+// function doesn't exist. However calling that when using Microsoft's

+// System.Convert doesn't produce any compiler errors, it just throws

+// an InvalidCastException at runtime.

+//

+// Whenever a decimal, double, or single is converted to an integer

+// based type, it is even rounded. This uses Math.Round which only 

+// has Round(decimal) and Round(double), so in the Convert from 

+// single cases the value is passed to Math as a double. This 

+// may not be completely necessary.

+//

+// The .NET Framework SDK lists DBNull as a member of this class

+// as 'public static readonly object DBNull;'. 

+//

+// It should also be decided if all the cast return values should be

+// returned as unchecked or not.

+//

+// All the XML function comments were auto generated which is why they

+// sound someone redundant.

+// Format integer types. Completely based off ECMA docs

+//
+// If you make any changes, please make sure to check the
+// boundry format precisions (0, 99) and the min / max values
+// of the data types (Int32.[Max/Min]Value).
+//
+// Using int as an example, it is currently set up as
+//
+// Int32 {
+//   int value;
+//   public string ToString (string format, NumberFormatInfo nfi) {
+//      return IntegerFormatter.NumberToString (format, nfi, value);

+//        case 'R' throw Exception("Invalid blah blah");
+//        case 'C' FromatCurrency(value, precision, nfi);
+//        etc...
+//      }
+//   }
+// }
+//
+// There is a property in NumberFormatInfo for NegativeSign, though the 
+// definition of IFormattable just uses '-' in context. So all the 
+// hardcoded uses of '-' in here may need to be changed to nfi.NegativeSign
+//
+// For every integral type.
+//
+// Before every Format<Format Type> block there is a small paragraph
+// detailing its requirements, and a blurb of what I was thinking
+// at the time.
+//
+// Some speedup suggestions to be done when after this appears
+// to be working properly:
+//
+//   * Deal w/ out of range numbers better. Specifically with
+//     regards to boundry cases such as Long.MinValue etc.
+//     The previous way of if (value < 0) value = -value;
+//     fails under this assumption, since the largest
+//     possible MaxValue is < absolute value of the MinValue.
+//     I do the first iteration outside of the loop, and then
+//     convert the number to positive, then continue in the loop.
+//
+//   * Replace all occurances of max<Type>Length with their 
+//     numerical values. Plus the places where things are set
+//     to max<Type>Length - 1. Hardcode these to numbers.
+//
+//   * Move the code for all the NumberToString()'s into the
+//     the main ToString (string, NumberFormatInfo) method in
+//     the data types themselves. That way they'd be throwing
+//     their own exceptions on error and it'd save a function
+//     call.
+//
+//   * For integer to char buffer transformation, you could
+//     implement the calculations of the 10's and 100's place
+//     the same time w/ another table to shorten loop time.
+//
+//   * Someone smarter can prolly find a much more efficient 
+//     way of formatting the exponential notation. It's still
+//     done in pass, just may have too many repositioning
+//     calculations.
+//   
+//   * Decide whether it be better to have functions that
+//     handle formatting for all types, or just cast their
+//     values out and format them. Just if library size is
+//     more important than speed in saving a cast and a 
+//     function call.

+		//  CurrencyDecimalSeparator members of a NumberFormatInfo supply
+		//  the currency symbol, size and separator for digit groupings, and
+		//  decimal separator, respectively.
+		//  CurrencyNegativePattern and CurrencyPositivePattern determine the
+		//  symbols used to represent negative and positive values. For example,
+		//  a negative value may be prefixed with a minus sign, or enclosed in
+		//  parentheses.
+		//  If the precision specifier is omitted
+		//  NumberFormatInfo.CurrencyDecimalDigits determines the number of
+		//  decimal places in the string. Results are rounded to the nearest
+		//  representable value when necessary.
+		//
+		//  The pattern of the NumberFormatInfo determines how the output looks, where
+		//  the dollar sign goes, where the negative sign goes, etc.
+		//  IFormattable documentation lists the patterns and their values,
+		//  I have them commented out in the large switch statement

+		//  a negative value may be prefixed with a minus sign, or enclosed in
+		//  parentheses.
+		//  If no precision is specified, the number of decimal places in the result
+		//  is set by NumberFormatInfo.PercentDecimalDigits. Results are
+		//  rounded to the nearest representable value when necessary.
+		//  The result is scaled by 100 (.99 becomes 99%).
+		//
+		//  The pattern of the number determines how the output looks, where
+		//  the percent sign goes, where the negative sign goes, etc.

+System.Object:

+System.ValueType:
+	Need to lock memory and "scan" the actual contents to compute
+	hash code and do comparissions.  Should be simple to do with
+	C#, the problem is figuring out the size of the object.
+
+System.String:
+	Need to implement the Format() and CompareOrdinal() methods 
+	as we all implement all of the methods that take into account 
+	CultureInfo or Encoding stuff.
+
+System.Array:
+	It's not possible to test to see if the whole thing works, as
+	GetValue() and SetValue() make calls into the runtime. However,
+	I've tried my implementations of things like BinarySearch() and
+	Sort() on the MS-provided System.Array and they seem to work fine.
+	According to the spec, System.Array implements the IList interface.
+	The spec doesn't have the methods for those interfaces, however,
+	the class doesn't (yet) implement that interface and those methods
+	are not (yet) written.

+2002-07-24  Duncan Mak  <duncan@ximian.com>
+
+	* corlib_linux_test.args: Add Cesar's BufferTest to the list.
+
+2002-07-19  Martin Baulig  <martin@gnome.org>
+
+	* makefile.gnu: Added makefile for self-hosting compile on GNU/Linux.
+	Don't add this to the top-level makefile.gnu, this must be run after
+	everything is compiled.
+
+2002-07-19  Martin Baulig  <martin@gnome.org>
+
+	The test suite now compiles with MCS on GNU/Linux :-)
+
+	* corlib_linux_test.args: Added MCS command file to compile this.
+
+2002-07-11  Nick Drochak  <ndrochak@gol.com>

+

+	* .cvsignore: Ignore temp files too.

+

+2002-06-19  Nick Drochak  <ndrochak@gol.com>

+

+	* AllTests.cs: Add missing test: System.Runtime.Serialization.

+

+2002-06-01  Nick Drochak  <ndrochak@gol.com>

+

+	* corlib_test.build: Change the order of the builds.  Just makes it a 

+	bit faster for my testing since I need the linux dll.

+

+2002-05-19  Martin Baulig  <martin@gnome.org>
+
+	* Added System.Security.Cryptography.FromBase64TransformTest.cs.
+
+2002-05-19  Martin Baulig  <martin@gnome.org>
+
+	* TheTests.cs: Removed.
+
+	* MartinTests.cs: Removed.
+
+	* corlib_test.build: Don't create Runtest.corlib.exe anymore.
+
+2002/05/07  Nick Drochak <ndrochak@gol.com>

+

+	* AllTests.cs: Do not run the System.Net tests from here, they belong

+	in the System assembly tests.

+

+2002-04-27  Lawrence Pit <loz@cable.a2000.nl>

+

+	* System.Security/: added directory

+	* AllTests.cs: added Syste,Security suite.

+

+2002-04-15  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* System.Net/: added directory.
+	* AllTests.cs: added System.Net suite.
+
+2002/04/04 Nick Drochak <ndrochak@gol.com>

+

+ 	* corlib_test.build: Again; disable running of NUnit tests against mono 

+	corlib.  There are so many icalls now, that these tests need

+	to be run inside mint and mono.  Will change this soon to run

+	the tests using both.  It still runs the tests against the mscorlib

+	to validate the tests themselves.

+

+2002-03-31  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* corlib_test.build: don't exclude IntegerFormatterTest.
+
+	* System/AllTests.cs: added IntegerFormatterTest suite.
+
+	* System/IntegerFormatterTest.cs: totally reworked to use NUnit. Right
+	now it fails cause I haven't implemented Parse () methods yet. With
+	corlib_reference.dll runs ok.
+
+2002/03/28  Nick Drochak <ndrochak@gol.com>

+

+	* corlib_test.build: Re-exclude it in a couple of places where it was

+	breaking the build.  This test is not an NUnit test.  So, it doesn't 

+	belong in these dll's until it's made a proper NUnit test.

+

+2002-03-28  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* corlib_test.build: remove two more lines that excluded
+	IntegerFormatterTest.
+
+2002/03/28  Nick Drochak <ndrochak@gol.com>

+

+	* corlib_test.build: Don't exclude IntegerFormatterTest any more.

+

+2002-03-20  Nick Drochak  <ndrochak@gol.com>

+

+	* corlib_test.build: On 'clean' remove all the dll's and pdb's

+

+2002/03/19  Nick Drochak <ndrochak@gol.com>

+

+	* corlib_test.build: Re-include tests into the build.

+

+2002-03-18  Nick Drochak  <ndrochak@gol.com>

+

+	* corlib_test.build: build RunTests.corlib.exe with only mono class

+	libs. This tells what we are missing to run the tests.

+

+2002/03/18  Nick Drochak <ndrochak@gol.com>

+

+	* corlib_test.build: disable running of NUnit tests against mono 

+	corlib.  There are so many icalls now, that these tests need

+	to be run inside mint and mono.  Will change this soon to run

+	the tests using both.  It still runs the tests against the mscorlib

+	to validate the tests themselves.

+

+2002/03/07  Nick Drochak <ndrochak@gol.com>

+

+	* corlib_test.build: resolve chicken and egg problem. Only build and 

+	execute test assemblies when 'make test' is specified. Need to do a

+	'make' first now before 'make test'.

+

+2002-03-03  Nick Drochak  <ndrochak@gol.com>

+

+	* corlib_test.build: Turn on debug flag for complier so that...well...

+	debugging is easier.

+

+2002-03-01  Duncan Mak  <duncan@ximian.com>
+
+	* System.Runtime.Serialization/ObjectIDGeneratorTests.cs: Added
+	test for System.Runtime.Serialization.ObjectIDGenerator.
+
+2002-02-27  Martin Baulig  <martin@gnome.org>
+
+	* RunTests.cs: Removed. This is now in the nant directory.
+
+	* corlib_test.build: Don't link TheTests.cs into the dlls, renamed
+	RunTests.exe to RunTests.corlib.exe and link it against NUnitBase.dll.
+
+2002-02-27  Martin Baulig  <martin@gnome.org>
+
+	* scan-tests.pl: Moved to ../../../tools/.
+
+2002-02-26  Martin Baulig  <martin@gnome.org>
+
+	* MartinTests.cs: New file. This contains all the tests which already
+	work on Linux.
+
+	* RunTests.cs: A small custom testrunner to run the tests on Linux.
+
+	* scan-tests.pl: Call this perl script with either MartinTests.cs or
+	AllTests.cs as argument and redirect the output the TheTests.cs - it'll
+	create a file which calls all the tests.
+
+	* TheTests.cs: This is automatically generated from scan-tests.pl but
+	needs some manual editing, so it's in CVS.
+
+	* corlib_test.build: In addition to the libraries, create an executable
+	called RunTests.exe which contains all the tests and the custom test
+	runner. You can run this executable on Windows to test things with
+	mscorlib or on Linux using the mono runtime.
+
+2002-02-26  Martin Baulig  <martin@gnome.org>
+
+	* */*.cs: added zero-args constructors for all the test classes.
+
+2002-02-21  Mark Crichton <crichton@gimp.org>
+
+	* System.Security.Cryptography.RNGCryptoServiceProviderTest.cs:
+	Fixed typo
+
+2002-02-21  Mark Crichton <crichton@gimp.org>
+
+	* Addded System.Security.Cryptography.RNGCryptoServiceProviderTest.cs
+	* System.Security.Cryptography/AllTests.cs: Added
+	RNGCryptoServiceProviderTest.
+
+2002-02-17  Duco Fijma <duco@lorentz.xs4all.nl>

+	* Added System/GuidTest.cs

+

+2002-02-10  Nick Drochak  <ndrochak@gol.com>

+

+	* corlib_test.build: Remove duplicate excludes for 

+	* AllTests.cs: Add System.Security.Policy tests.  However, commented

+	this out because NUnit is throwing an exception.  Need to figure

+	that out first.

+	

+2002-02-09  Nick Drochak  <ndrochak@gol.com>

+

+	* corlib_test.build: compile with mscorlib to test the tests.  This

+	will be our "reference" check to make sure the tests work.

+

+2002-01-25  Nick Drochak  <ndrochak@gol.com>

+

+	* AllTests.cs: Add System.Resources.AllTests.Suite

+

+2002-01-14  Nick Drochak  <ndrochak@gol.com>

+

+	* AllTests.cs: Add System.Security.Permissions.AllTests.Suite

+

+2002-01-05  Nick Drochak  <ndrochak@gol.com>

+

+	* .cvsignore: ignore the debug files *.pdb

+

+2002-01-04   Duco Fijma <duco@lorentz.xs4all.nl>

+	* Added System/TimeSpanTest.cs

+

+2002-01-04  John R. Hicks <angryjohn69@nc.rr.com>

+	* Added DebugTest to System.Diagnostics tests.

+2001-11-08  Nick Drochak  <ndrochak@gol.com>

+

+	* corlib_test.build: Include test for Queue in the dll

+

+2001-10-15  Martin Weindel <martin.weindel@t-online.de>

+

+        * added System/DecimalTest.cs and System/DecimalTest2.cs

+

+2001-10-11  Jeffrey Stedfast  <fejj@ximian.com>

+

+	* System/StringTest.cs: Added.

+

+2001-10-10  Thomas Neidhart <tome@sbox.tugraz.at>

+

+	* added directory System.Security.Cryptography 

+	* added TestSuite for all Crypto classes 

+	* added tests for System.Security.Cryptography.AsymmetricAlgorithm 

+	and System.Security.Cryptography.SymmetricAlgorithm

+    

+2001-10-02  Martin Weindel <martin.weindel@t-online.de>

+

+	* added directory System 

+	* added tests for System.Int64

+

+2001-08-29  Alexander Klyubin <klyubin@aqris.com>

+  

+	* Added tests for System.Diagnostics.StackFrame and

+	System.Diagnostics.StackTrace. The tests only run against

+	Microsoft's implementation as StackTrace and StackFrame classes in

+	Mono are not yet properly implemented.

+    

+	Note that StackFrameTest runs properly only if compiled with

+	/debug switch.

+
+	* FileTest.cs: Delete temporary files after each test method; Catch
+	unexpected exceptions and report them; Make some Assert messages
+	unique; Make sure temp files exist before trying Move and Delete, etc.

+
+	* FileTest.cs: Adding better tests for File.Delete, File.Move
+

+	and File.Copy
+
+2002-05-12  Nick Drochak  <ndrochak@gol.com>
+
+	* StringTest.cs: Add a couple more tests.
+	* PathTest.cs: Make tests work a bit better on W32 and Linux.
+
+2002/05/10  Nick Drochak <ndrochak@gol.com>
+
+	* StreamWriterTest.cs: Use "resources" directory and use OS friendly
+	directory separator characters.  This makes the tests run correctly

+	what exception is being thrown when it shouldn't.
+
+2002-05-07  Nick Drochak  <ndrochak@gol.com>
+
+	* FileTest.cs: Added TestOpen() from Mike Gray.
+	* AllTests.cs: Added missing FileTest.Suite as pointed out by Mike 
+	as well.
+
+2002-05-05  Nick Drochak  <ndrochak@gol.com>
+
+	* StreamReaderTest.cs: Change location of sample file. In some places,
+	use memory stream instead of file stream to eliminate reliance on file 
+	io for now.  That area is still a bit immature. Added a bunch of 
+	markers to tell where errors were occuring.

+	* resources: New directory to hold files open/read, etc. by unit
+	tests.
+
+2002-05-01  Nick Drochak  <ndrochak@gol.com>
+
+	* StreamReaderTest.cs:
+	* StreamWriterTest.cs: Catch and display exception info where it wasn't
+	being caught before.
+
+2002-03-02  Jason Diamond  <jason@injektilo.org>
+
+	* StringReader.cs: Added test for peeking and reading at the end of
+	a string.
+
+2002-02-28  Nick Drochak  <ndrochak@gol.com>
+
+	* MemoryStreamTest.cs 
+	* StreamWriterTest.cs 
+	* StringReaderTest.cs: Fix test bugs found by running against mscorlib.
+	AssertEquals() requires the expected and atual values to be the same
+	type if they are to be considered equal.
+
+2002-02-05  Duncan Mak  <duncan@ximian.com>
+
+	* FileTest.cs: Added to CVS. However, this portion of the code
+	can't be tested right now.
+
+2002-01-20 Nick Drochak  <ndrochak@gol.com>
+
+	* AllTests.cs: removed duplicate MemoryStream test
+	* MemoryStreamTest.cs: wrapped try-catch blocks around read/write/seek
+	tests. These were throwing exceptions that NUnit wasn't catching.  I 
+	don't think it used to behave this way before .NET.1.0.

+	* ArrayTest.cs: Disable a test for now.  Bugzilla'd this one.
+	* ConvertTest.cs: Make message unique for this mistaken duplicate.
+
+2002-07-04  Nick Drochak  <ndrochak@gol.com>
+
+	* DateTimeTest.cs: Made tests pass on ms.net.  Well, they pass in
+	timezone JST.  Need to test in others.  Maybe I'll fly over to GMT
+	and see how they work.  Supposed to be eaiser there.
+
+2002-07-04  Nick Drochak  <ndrochak@gol.com>
+
+	* ConvertTest.cs: Make the test generate the overflow exceptions on
+	mono on Linux.
+	* DecimalTest2.cs: Report exception thrown during subtraction.
+
+2002-07-03  Nick Drochak  <ndrochak@gol.com>
+
+	* DoubleTest.cs: Fix some Assert/AssertEquals usage.
+
+2002-07-03  Nick Drochak  <ndrochak@gol.com>
+
+	* ArrayTest.cs: Re-enable some tests.  Let's see what's broken still.
+
+2002-06-20  Nick Drochak  <ndrochak@gol.com>
+
+	* DecimalTest2.cs: Make tests pass against ms.net.
+
+2002-06-19  Nick Drochak  <ndrochak@gol.com>
+
+	* AllTests.cs: Add missing test: DecimalTest2
+	* DecimalTest2.cs: Convert Console.Writeline() into a Fail()
+
+2002/06/14  Nick Drochak <ndrochak@gol.com>
+
+	* Int64Test.cs: Make currency symbol test more culturally sensitive.
+
+2002-06-14  Nick Drochak  <ndrochak@gol.com>
+
+	* DateTimeTest.cs: Make some of the tests a bit more timezone neutral.
+
+2002-06-12   Nick Drochak  <ndrochak@gol.com>
+
+	* ConvertTest.cs: Punt bug in DateTime.Parse() over to that test.
+	* DateTimeTest.cs: Add test for date format of yyyy-mm-dd which mono
+	doesn't handle automagically like ms.net does.  This smells like a 
+	LAMESPEC, however.
+
+2002/06/12  Nick Drochak <ndrochak@gol.com>
+
+	* RandomTest.cs: Exercise Next(min,max) a little more, especially
+	boundary conditions.
+
+2002-06-11  Nick Drochak  <ndrochak@gol.com>
+
+	* StringTest.cs: Check for "end of string" conditions for IndexOf() and
+	Substring().
+
+2002-06-11  Nick Drochak  <ndrochak@gol.com>
+
+	* DoubleTest.cs: Add some more detail to failure message.

+	* TimeZoneTest.cs: Same.
+
+2002-06-11  Nick Drochak  <ndrochak@gol.com>
+
+	* Int64Test.cs: Set the culture to en-US for testing.
+	* MathTest.cs: mono is more precise in Log2, so change test to compare
+	values within a slightly larger margin of error.
+
+2002/06/10  Nick Drochak <ndrochak@gol.com>
+
+	* DecimalTest.cs: More culture indepenence. Fixes the problems we were
+	having with tests failing against MS.NET.
+	* Int64Test.cs: Same plus some formatting fixes.
+	* RandomTest.cs: Split Assert into two to figure out which one part is
+	failing.
+
+2002-06-09  Lawrence Pit  <loz@cable.a2000.nl>

+

+	* DateTimeTest.cs: Making tests culture independent

+

+2002-06-07  Nick Drochak  <ndrochak@gol.com>
+
+	* DecimalTest.cs: Catch unexpected exception and report it.
+
+2002/06/04  Nick Drochak <ndrochak@gol.com>
+

+	value.  Try to be more culture-diverse.
+
+2002/06/03  Nick Drochak <ndrochak@gol.com>
+
+	* DecimalTest.cs: Fix some errors that were showing up when run against
+	ms.net.
+
+2002-06-02  Nick Drochak  <ndrochak@gol.com>
+
+	* ConvertTest.cs: Use en-US culture since that's all we support in our
+	corlib right now. Change constants accordingly.  Also added a bunch of
+	try-catch blocks to show which Assert is failing.
+
+2002-06-02  Duncan Mak  <duncan@ximian.com>
+
+	* ConvertTest.cs (TestToDecimal): Fixed typo in case #H11.
+
+2002-06-01  Nick Drochak  <ndrochak@gol.com>
+
+	* BugTest.cs: Remove, bug fixed.  Yay!
+	* AllTests.cs: Remove BugTest from suite.
+
+2002-05-31  Nick Drochak  <ndrochak@gol.com>
+
+	* BugTest.cs: Small file to show NullReferenceException bug
+	* AllTests.cs: Include BugTest.cs in the suite.
+
+2002-05-29  Nick Drochak  <ndrochak@gol.com>

+2002-05-29  Lawrence Pit  <loz@cable.a2000.nl>

+

+	* DateTimeTest.cs: Added tests M01 to M03 to TestParseExact, 

+	passing typeof this class as arg in property Suite.

+

+2002-05-22  Lawrence Pit  <loz@cable.a2000.nl>

+

+	* ConsoleTest.cs: Added test writing null.

+

+2002-05-21  Nick Drochak  <ndrochak@gol.com>
+
+	* MathTest.cs:
+		(TestPow): Add try-catch to determine where we are throwing.
+		(TestLog): Re-enable failing test
+		(TestLog2): same although this test still fails on mono. Not
+		sure what the proper value	to use here. It works on MS.NET
+
+2002-05-21  Nick Drochak  <ndrochak@gol.com>
+
+	* MathTest.cs: Better reporting of failures
+	* Int64Test.cs: Add try-catch to determine where we are throwing.
+
+2002-05-20  Nick Drochak  <ndrochak@gol.com>

+

+	* StringTest.cs: Added test for replace function

+

+2002-04-30  Nick Drochak  <ndrochak@gol.com>
+
+	* UInt32Test.cs: More verbose on unexepected exception to eliminate
+	compiler warning.
+
+2002-04-28  Nick Drochak  <ndrochak@gol.com>
+
+	* StringTest.cs: Mark Assert() messages with unique identifiers.
+	* DecimalTest2.cs: Write out more info in the Report method.  Need this
+	to determine why op_Subtraction() is failing in the next line.
+	* MathTest.cs:
+	* DoubleTest.cs:
+	* UInt32Test.cs: Add try-catch blocks to find out where the test is
+	failing.
+
+2002-04-28  Nick Drochak  <ndrochak@gol.com>
+
+	* ArrayTest.cs (TestIList_IndexOf): Display exception details if we get
+	an unexpected one.
+
+2002/04/24  Nick Drochak <ndrochak@gol.com>
+
+	* IntegerFormatterTest.cs: Remove Console.WriteLines and use 
+	AssertEquals() instead.
+
+2002-04-22  Nick Drochak  <ndrochak@gol.com>
+
+	* StringTest.cs: Add unique markers to Assert messages.
+
+2002-04-09  Nick Drochak  <ndrochak@gol.com>
+
+	* ArrayTest.cs: Remove BinarySearch test on unsorted arrays. The
+	behavior is undefined if the array isn't sorted.
+
+2002/04/09  Nick Drochak <ndrochak@gol.com>
+
+	* DecimalTest.cs: Use AssertEquals() for better diagnostic message.
+
+2002-04-09  Nick Drochak  <ndrochak@gol.com>
+
+	* ByteTest.cs: Use AssertEquals() for better diagnostic message.
+
+2002-04-08  Nick Drochak  <ndrochak@gol.com>
+
+	* EnumTest.cs: Add a few tests for differently underlying types and
+	the [Flags] attribute to test ToString().
+
+2002-04-08  Nick Drochak  <ndrochak@gol.com>
+
+	* EnumTest.cs: Add test for ToString for the case where the enum
+	has [Flags] on it, and a mask value is used.
+
+2002-04-04  Nick Drochak  <ndrochak@gol.com>
+
+	* EnumTest.cs: Change one Assert() message string so the two are 
+	unique. And clean up exception catching logic.
+
+2002/03/28  Nick Drochak <ndrochak@gol.com>
+
+	* IntegerFormatterTest.cs: Eliminate warnings about unused exception
+	variables.
+
+2002-03-28  Nick Drochak  <ndrochak@gol.com>
+
+	* EnumTest.cs(TestFormat): Use Fail() instead of AssertEquals() in
+	try-catch blocks. Add test to check if correct exception is being 
+	thrown.
+
+2002/03/18  Nick Drochak <ndrochak@gol.com>
+
+	* ByteTest.cs:
+	* Int64Test.cs:
+	* SByteTest.cs: Do not hard code the "$" as the currency symbol to
+	use for Parse tests. This isn not really the fix we need. These
+	number formats vary wildly depending on the culture the system
+	runs with.  We need a much better strategy here for testing this.
+	* Int32Test.cs: Use #if NOTYET-#endif to disable a test.  This removes
+	an annoying compile warning.
+
+2002-03-18  Nick Drochak  <ndrochak@gol.com>
+
+	* DoubleTest.cs:
+	* EnumTest.cs: Add unique identifier to Assert()'s. Needed to find
+	which one was faling on Linux.
+
+2002-03-12  Nick Drochak  <ndrochak@gol.com>
+
+	* ArrayTest.cs: Add tests for IList methods and for enumerator on
+	an array with non-zero lower bounds.
+
+2002-03-09  Nick Drochak  <ndrochak@gol.com>
+
+	* ArrayTest.cs: Enable the enumerator test and include test for
+	Multi-dimensional array enumerator.  Also include test for
+	mutation _not_ invalidating the enumerator.
+
+2002-03-09  Martin Baulig  <martin@gnome.org>
+
+	* Int16Test.cs, Int32Tests.cs, UInt16Tests.cs: Use "en-US" culture and
+	don't let the user override.
+
+	* Int32Tests.cs: Cleanup. Use unique names in Assert()s, use AssertEquals()
+	where appropriate etc.
+
+2002-03-08  Martin Baulig  <martin@gnome.org>
+
+	* StringTest.cs: More String.Split tests.
+
+2002-03-07  Martin Baulig  <martin@gnome.org>
+
+	* StringTest.cs: Added a few more tests for the bug fixes I just
+	committed to String.cs.
+
+2002-03-07  Martin Baulig  <martin@gnome.org>
+
+	* ArrayTest.cs: Fixed the FIXME in test #E05.
+
+2002-03-06  Duco Fijma  <duco@lorentz.xs4all.nl>
+	* CharEnumeratorTest.cs: made test regarding out-of-bounds checking
+	a bit stronger (new failures fixed in CharEnumerator.cs).
+
+2002-03-06  Martin Baulig  <martin@gnome.org>
+
+	* ArrayTest.cs (TestSetValue4): Added testcases #M94-#M96 for Array.Copy.
+
+	* ArrayTest.cs (TestCopyTo): Added testcases #F10-#F13 for arrays with
+	non-zero lower bounds.
+
+	* ArrayTest.cs (TestCopyTo): Added test for copying an empty array
+	to an empty array.
+
+2002-03-06  Martin Baulig  <martin@gnome.org>
+
+	* ArrayTest.cs: Use unique labels for all the tests.
+	(TestSetValue4): A big new testcase.
+
+2002-03-06  Nick Drochak  <ndrochak@gol.com>

+

+	* VersionTest.cs: Fix for mscorlib behavior vs. docs. CompareTo(null)

+	is legal.

+	* UInt16Test.cs:

+	* UInt32Test.cs:

+	* UInt64Test.cs: Use NumberFormatInfo.InvariantInfo.CurrencySymbol

+	where "$" was used. Should help suppress false negatives on systems

+	where "$" is not the currency symbol.

+

+2002-03-04  Duco Fijma  <duco@lorentz.xs4all.nl>
+	* VersionTest.cs: created test cases for System.Version
+
+2002-03-03  Duco Fijma  <duco@lorentz.xs4all.nl>
+	* CharEnumeratorTest.cs: completed the test cases
+
+2002-03-03  Nick Drochak  <ndrochak@gol.com>

+

+	* DateTimeTest.cs: make static member non-static -- wouldn't work on 

+	Windows if it was static. Doesn't _need_ to be static anyway.

+

+2002-03-01  Duco Fijma  <duco@lorentz.xs4all.nl>
+	* AttributeTest.cs: created, far from complete. 
+	* CharEnumeratorTest.cs: created. Contains just the basic case.
+	* AllTests.cs: added the two new tests above
+
+2002-03-01  Duco Fijma  <duco@lorentz.xs4all.nl>
+	* BitConverterTest.cs: added one test for bug fix made to BitConverter
+	* class.
+
+2002-03-01  Martin Baulig  <martin@gnome.org>
+
+	* ArrayTest.cs: Commented out a few bits which are not yet implemented and
+	marked them with FIXME's.
+
+	* DecimalTest.cs, DecimalTest2.cs: Added zero-arg constructors.
+
+	* MartinTests.cs: Enabled ArrayTests.cs.
+
+2002-03-01  Duco Fijma <duco@lorentz.xs4all.nl>
+
+	* BitConverterTest.cs: completed test cases
+
+2002-03-01  Martin Baulig  <martin@gnome.org>
+
+	* MartinTests.cs: 15 tests currently work on Linux, call them all and
+	provide comments for the non-working tests.
+
+2002-02-28  Duncan Mak  <duncan@ximian.com>
+
+	* MathTest.cs: Committed for Jon Guymon <gnarg@slackworks.com>.
+
+2002-02-28  Martin Baulig  <martin@gnome.org>
+
+	* String.cs (TestCompare): Added a few tests.
+	(TestFormat): Please don't compare two strings with Assert (... == ...),
+	use AssertEquals instead - this gives you a better idea what went wrong
+	if the test fails.
+
+2002-02-28  Nick Drochak  <ndrochak@gol.com>
+
+	* BitConverterTest.cs: Test was trying to catch the wrong Exception.
+	The MSDN docs clearly say ArgumentOutOfRangeException, but that's
+	not what get's thrown.
+
+	* DoubleTest.cs: Get working against mscorlib reference.
+
+2002-02-27  Duco Fijma <duco@lorentz.xs4all.nl>
+	* GuidTest.cs: changed to reflect new meaning of Guid.ToString("")
+	and Guid.ToString(null)
+
+2002-02-26  Martin Baulig  <martin@gnome.org>
+
+	* MartinTests.cs: New file. This contains all the test which already
+	work on Linux.
+
+	* String.cs: Added two testcases to TestTrim(), TestTrimStart() and
+	TestTrimEnd().
+
+2002-02-26  Martin Baulig  <martin@gnome.org>
+
+	* DateTimeTest.cs: Added testcases for the parsers. Use the invariant
+	culture to run this test suite.
+
+	* TimeZoneTest.cs: Use the invariant culture to run this test suite.
+
+2002-02-26  Duco Fijma <duco@lorentz.xs4all>
+	* TimeSpanTest.cs: added test from TimeSpan.FromMilliseconds
+
+2002-02-26  Martin Baulig  <martin@gnome.org>
+
+	* DateTimeTest.cs: New test.
+
+	* TimeZoneTest.cs: New test.
+
+2002-02-25  Duco Fijma <duco@lorentz.xs4all.nl>
+	* GuidTest.cs: all methods of System.Guid are now covered
+	* BitConverterTest.cs: created, not yet complete
+
+2002-02-21  Duco Fijma <duco@lorentz.xs4all.nl>
+	* GuidTest.cs: changed according to fix in System.Guid
+
+2002-02-20  Nick Drochak  <ndrochak@gol.com>

+

+	* Int64Test.cs: One array was giving us trouble.  Not sure why, but

+	it's related to the number of elements in an Array.  For short Arrays

+	the compiler doesn't use the PrivateImplmentationDetails struct,

+	but for longer ones it does.  That's when our corlib fails. I paired

+	down the array for now.

+

+2002-02-19  Duco Fijma <duco@lorentz.xs4all.nl>

+	* GuidTest.cs: added a few cases

+

+2002-02-18  Nick Drochak  <ndrochak@gol.com>

+

+	* GuidTest.cs: Fix compile error.  Needed to cast the null in the call to

+	constructor to avoid ambiguity.

+

+2002-02-11  Nick Drochak  <ndrochak@gol.com>

+

+	* Int64Test.cs: Various fixes to make tests work against the ms corlib.

+	Currency Symbol tests seem to be system dependant.  Not sure if this

+	will work on other systems, so please test it if you can. The most

+	disturbing one is negative numbers.  Should they be (n) or -n ?

+

+2002-02-10  Nick Drochak  <ndrochak@gol.com>

+

+	* AllTests.cs: Add Int64Test to the Suite

+	* Int64Test.cs: Change static member to instance member. This was

+	causing NUnitConsole some grief.  Should be instance member anyway.

+

+2002-02-09  Nick Drochak  <ndrochak@gol.com>

+

+	* ByteTest.cs:

+	* Int16Test.cs:

+	* Int32Test.cs:

+	* SByteTest.cs:

+	* UInt16Test.cs:

+	* UInt32Test.cs:

+	* UInt64Test.cs: Fixed tests where a "$" was hard coded.  Change it to

+	use NumberFormatInfo.CurrentInfo.CurrencySymbol.  Also used

+	NumberFormatInfo.InvariantInfo.CurrencySymbol where appropriate. These

+	tests all pass now with mscorlib.

+

+2002-01-06  Nick Drochak  <ndrochak@gol.com>

+

+	* ResolveEventArgsTest.cs: New test.

+	* AllTests.cs: Added new test to suite.

+

+2001-12-27  Nick Drochak <ndrochak@gol.com>

+

+	* UInt32Test.cs: Added messages to Asserts()'s to find out which one was faliing.

+

+2001-12-21  Miguel de Icaza  <miguel@ximian.com>

+

+	* UInt32Test.cs: Added tests for UInt32.Parse.

+

+	* Int32Test.cs: Added tests for Int32.Parse for various cases.

+

+2001-12-08  Nick Drochak  <ndrochak@gol.com>

+

+	* ByteTest.cs: Added messages to Assert()'s to find out which one was failing.

+

+2001-11-28  Nick Drochak <ndrochak@gol.com>

+

+	* Int16Test.cs Int32Test.cs SByteTest.cs: Surgically removed tests that rely on culture of system.  These need to be crafted a bit differently.

+

+2001-11-27  Nick Drochak  <ndrochak@gol.com>

+

+	* SByteTest.cs: Add messages to Assert()'s so we can tell where the tests fail.

+

+2002-02-21  Bob Doan  <bdoan@sicompos.com>

+

+	* BooleanTest.cs: Added New test suite

+	* AllTests.cs: Added new Boolean test to suite.

+

+2002-02-24  Bob Doan  <bdoan@sicompos.com>

+

+	* BooleanTest.cs: Use correct argument order in AssertEquals

+	* AllTests.cs: Added new Double test to suite.

+	* DoubleTest.cs: Add new test suite

+

+2002-02-24  Bob Doan  <bdoan@sicompos.com>

+

+	* DoubleTest.cs: Added parse tests to Double test suite, removed GetHashCodeTests

+
+* Abstract
+
+	The Mono C# compiler is a C# compiler written in C# itself.
+	Its goals are to provide a free and alternate implementation

+
+	The compilation process is managed by the compiler driver (it
+	lives in driver.cs).
+
+	The compiler reads a set of C# source code files, and parses
+	them.  Any assemblies or modules that the user might want to
+	use with his project are loaded after parsing is done.
+
+	Once all the files have been parsed, the type hierarchy is
+	resolved.  First interfaces are resolved, then types and
+	enumerations.
+
+	Once the type hierarchy is resolved, every type is populated:
+	fields, methods, indexers, properties, events and delegates
+	are entered into the type system.  
+
+	At this point the program skeleton has been completed.  The
+	next process is to actually emit the code for each of the
+	executable methods.  The compiler drives this from
+	RootContext.EmitCode.
+
+	Each type then has to populate its methods: populating a
+	method requires creating a structure that is used as the state
+	of the block being emitted (this is the EmitContext class) and
+	then generating code for the topmost statement (the Block).
+
+	Code generation has two steps: the first step is the semantic
+	analysis (Resolve method) that resolves any pending tasks, and
+	guarantees that the code is correct.  The second phase is the
+	actual code emission.  All errors are flagged during in the
+	"Resolution" process. 
+
+	After all code has been emitted, then the compiler closes all
+	the types (this basically tells the Reflection.Emit library to
+	finish up the types), resources, and definition of the entry
+	point are done at this point, and the output is saved to
+	disk. 
+
+* The parsing process
+
+	All the input files that make up a program need to be read in
+	advance, because C# allows declarations to happen after an
+	entity is used, for example, the following is a valid program:
+
+	class X : Y {
+		static void Main ()
+		{
+			a = "hello"; b = "world";
+		}
+		string a;
+	}
+	
+	class Y {
+		public string b;
+	}
+
+	At the time the assignment expression `a = "hello"' is parsed,
+	it is not know whether a is a class field from this class, or
+	its parents, or whether it is a property access or a variable
+	reference.  The actual meaning of `a' will not be discvored
+	until the semantic analysis phase.
+
+** The Tokenizer and the pre-processor
+
+	The tokenizer is contained in the file `cs-tokenizer.cs', and
+	the main entry point is the `token ()' method.  The tokenizer
+	implements the `yyParser.yyInput' interface, which is what the
+	Yacc/Jay parser will use when fetching tokens.  
+
+	Token definitions are generated by jay during the compilation
+	process, and those can be references from the tokenizer class
+	with the `Token.' prefix. 
+
+	Each time a token is returned, the location for the token is
+	recorded into the `Location' property, that can be accessed by
+	the parser.  The parser retrieves the Location properties as
+	it builds its internal representation to allow the semantic
+	analysis phase to produce error messages that can pin point
+	the location of the problem. 
+
+	Some tokens have values associated with it, for example when
+	the tokenizer encounters a string, it will return a
+	LITERAL_STRING token, and the actual string parsed will be
+	available in the `Value' property of the tokenizer.   The same
+	mechanism is used to return integers and floating point
+	numbers. 
+
+	C# has a limited pre-processor that allows conditional
+	compilation, but it is not as fully featured as the C
+	pre-processor, and most notably, macros are missing.  This
+	makes it simple to implement in very few lines and mesh it
+	with the tokenizer.
+
+	The `handle_preprocessing_directive' method in the tokenizer
+	handles all the pre-processing, and it is invoked when the '#'
+	symbol is found as the first token in a line.  
+
+	The state of the pre-processor is contained in a Stack called
+	`ifstack', this state is used to track the if/elif/else/endif
+	nesting and the current state.  The state is encoded in the
+	top of the stack as a number of values `TAKING',
+	`TAKEN_BEFORE', `ELSE_SEEN', `PARENT_TAKING'.
+
+** Locations
+
+	Locations are encoded as a 32-bit number (the Location
+	struct) that map each input source line to a linear number.
+	As new files are parsed, the Location manager is informed of
+	the new file, to allow it to map back from an int constant to
+	a file + line number. 
+
+	The tokenizer also tracks the column number for a token, but
+	this is currently not being used or encoded.  It could
+	probably be encoded in the low 9 bits, allowing for columns
+	from 1 to 512 to be encoded.
+
+* The Parser
+
+	The parser is written using Jay, which is a port of Berkeley
+	Yacc to Java, that I later ported to C#. 
+
+	Many people ask why the grammar of the parser does not match
+	exactly the definition in the C# specification.  The reason is
+	simple: the grammar in the C# specification is designed to be
+	consumed by humans, and not by a computer program.  Before
+	you can feed this grammar to a tool, it needs to be simplified
+	to allow the tool to generate a correct parser for it. 
+
+	In the Mono C# compiler, we use a class for each of the
+	statements and expressions in the C# language.  For example,
+	there is a `While' class for the the `while' statement, a
+	`Cast' class to represent a cast expression and so on.
+
+	There is a Statement class, and an Expression class which are
+	the base classes for statements and expressions. 
+
+** Namespaces
+	
+	Using list.
+
+* Internal Representation
+
+** Expressions
+
+	Expressions in the Mono C# compiler are represented by the
+	`Expression' class.  This is an abstract class that particular
+	kinds of expressions have to inherit from and override a few
+	methods.
+
+	The base Expression class contains two fields: `eclass' which
+	represents the "expression classification" (from the C#
+	specs) and the type of the expression.
+
+	Expressions have to be resolved before they are can be used.
+	The resolution process is implemented by overriding the
+	`DoResolve' method.  The DoResolve method has to set the
+	`eclass' field and the `type', perform all error checking and
+	computations that will be required for code generation at this
+	stage. 
+
+	The return value from DoResolve is an expression.  Most of the
+	time an Expression derived class will return itself (return
+	this) when it will handle the emission of the code itself, or
+	it can return a new Expression.
+
+	For example, the parser will create an "ElementAccess" class
+	for:
+
+		a [0] = 1;
+
+	During the resolution process, the compiler will know whether
+	this is an array access, or an indexer access.  And will
+	return either an ArrayAccess expression or an IndexerAccess
+	expression from DoResolve.
+
+
+
+*** The Expression Class
+
+	The utility functions that can be called by all children of
+	Expression. 
+
+** Constants
+
+	Constants in the Mono C# compiler are reprensented by the
+	abstract class `Constant'.  Constant is in turn derived from
+	Expression.  The base constructor for `Constant' just sets the
+	expression class to be an `ExprClass.Value', Constants are
+	born in a fully resolved state, so the `DoResolve' method
+	only returns a reference to itself.
+
+	Each Constant should implement the `GetValue' method which
+	returns an object with the actual contents of this constant, a
+	utility virtual method called `AsString' is used to render a
+	diagnostic message.  The output of AsString is shown to the
+	developer when an error or a warning is triggered.
+
+	Constant classes also participate in the constant folding
+	process.  Constant folding is invoked by those expressions
+	that can be constant folded invoking the functionality
+	provided by the ConstantFold class (cfold.cs).   
+
+	Each Constant has to implement a number of methods to convert
+	itself into a Constant of a different type.  These methods are
+	called `ConvertToXXXX' and they are invoked by the wrapper
+	functions `ToXXXX'.  These methods only perform implicit
+	numeric conversions.  Explicit conversions are handled by the
+	`Cast' expression class.
+
+	The `ToXXXX' methods are the entry point, and provide error
+	reporting in case a conversion can not be performed.
+
+** Constant Folding
+
+	The C# language requires constant folding to be implemented.
+	Constant folding is hooked up in the Binary.Resolve method.
+	If both sides of a binary expression are constants, then the
+	ConstantFold.BinaryFold routine is invoked.  
+
+	This routine implements all the binary operator rules, it
+	is a mirror of the code that generates code for binary
+	operators, but that has to be evaluated at runtime.
+
+	If the constants can be folded, then a new constant expression
+	is returned, if not, then the null value is returned (for
+	example, the concatenation of a string constant and a numeric
+	constant is deferred to the runtime). 
+
+** Side effects
+
+	a [i++]++ 
+	a [i++] += 5;
+
+** Statements
+
+* The semantic analysis 
+
+	Hence, the compiler driver has to parse all the input files.
+	Once all the input files have been parsed, and an internal
+	representation of the input program exists, the following
+	steps are taken:
+
+		* The interface hierarchy is resolved first.
+	 	  As the interface hierarchy is constructed,
+		  TypeBuilder objects are created for each one of
+		  them. 
+
+		* Classes and structure hierarchy is resolved next,
+		  TypeBuilder objects are created for them.
+
+		* Constants and enumerations are resolved.
+
+		* Method, indexer, properties, delegates and event
+		  definitions are now entered into the TypeBuilders. 
+
+		* Elements that contain code are now invoked to
+		  perform semantic analysis and code generation.
+
+* Output Generation
+
+** Code Generation
+
+	The EmitContext class is created any time that IL code is to
+	be generated (methods, properties, indexers and attributes all
+	create EmitContexts).  
+
+	The EmitContext keeps track of the current namespace and type
+	container.  This is used during name resolution.
+
+	An EmitContext is used by the underlying code generation
+	facilities to track the state of code generation:
+
+		* The ILGenerator used to generate code for this
+		  method.
+
+		* The TypeContainer where the code lives, this is used
+		  to access the TypeBuilder.
+
+		* The DeclSpace, this is used to resolve names through
+	 	  RootContext.LookupType in the various statements and
+	 	  expressions. 
+	
+	Code generation state is also tracked here:
+
+		* CheckState:
+
+		  This variable tracks the `checked' state of the
+		  compilation, it controls whether we should generate
+		  code that does overflow checking, or if we generate
+		  code that ignores overflows.
+		  
+		  The default setting comes from the command line
+		  option to generate checked or unchecked code plus
+		  any source code changes using the checked/unchecked
+		  statements or expressions.  Contrast this with the
+		  ConstantCheckState flag.
+
+		* ConstantCheckState
+		  
+		  The constant check state is always set to `true' and
+		  cant be changed from the command line.  The source
+		  code can change this setting with the `checked' and
+		  `unchecked' statements and expressions.
+		  
+		* IsStatic
+		  
+		  Whether we are emitting code inside a static or
+		  instance method
+		  
+		* ReturnType
+		  
+		  The value that is allowed to be returned or NULL if
+		  there is no return type.
+		  
+		  
+		* ContainerType
+		  
+		  Points to the Type (extracted from the
+		  TypeContainer) that declares this body of code
+		  summary>
+		  
+		  
+		* IsConstructor
+		  
+		  Whether this is generating code for a constructor
+
+		* CurrentBlock
+
+		  Tracks the current block being generated.
+
+		* ReturnLabel;
+		
+		  The location where return has to jump to return the
+		  value
+
+	A few variables are used to track the state for checking in
+	for loops, or in try/catch statements:
+
+		* InFinally
+		
+		  Whether we are in a Finally block
+
+		* InTry
+
+		  Whether we are in a Try block
+
+		* InCatch
+		  
+		  Whether we are in a Catch block
+
+		* InUnsafe
+		  Whether we are inside an unsafe block
+		
+* Miscelaneous
+
+** Error Processing.
+
+	Errors are reported during the various stages of the
+	compilation process.  The compiler stops its processing if
+	there are errors between the various phases.  This simplifies
+	the code, because it is safe to assume always that the data
+	structures that the compiler is operating on are always
+	consistent.
+
+	The error codes in the Mono C# compiler are the same as those
+	found in the Microsoft C# compiler, with a few exceptions
+	(where we report a few more errors, those are documented in
+	mcs/errors/errors.txt).  The goal is to reduce confussion to
+	the users, and also to help us track the progress of the
+	compiler in terms of the errors we report. 
+
+	The Report class provides error and warning display functions,
+	and also keeps an error count which is used to stop the
+	compiler between the phases.  
+
+	A couple of debugging tools are available here, and are useful
+	when extending or fixing bugs in the compiler.  If the
+	`--fatal' flag is passed to the compiler, the Report.Error
+	routine will throw an exception.  This can be used to pinpoint
+	the location of the bug and examine the variables around the
+	error location.
+
+	Warnings can be turned into errors by using the `--werror'
+	flag to the compiler. 
+
+	The report class also ignores warnings that have been
+	specified on the command line with the `--nowarn' flag.
+
+	Finally, code in the compiler uses the global variable
+	RootContext.WarningLevel in a few places to decide whether a
+	warning is worth reporting to the user or not.

+and are not available in the version of NAnt (0.6) in our CVS tree.
+As I really don't want to go through the hell of getting the newer version

+            Microsoft ResX Schema 

+        

+            Version 1.3

+                

+            The primary goals of this format is to allow a simple XML format 

+            that is mostly human readable. The generation and parsing of the 

+            various data types are done through the TypeConverter classes 

+            associated with the data types.

+        

+            Example:

+        

+                ... ado.net/XML headers & schema ...

+                <resheader name="resmimetype">text/microsoft-resx</resheader>

+                <resheader name="version">1.3</resheader>

+                <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>

+                <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>

+                <data name="Name1">this is my long string</data>

+                <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>

+                <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">

+                    [base64 mime encoded serialized .NET Framework object]

+                </data>

+                <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">

+                    [base64 mime encoded string representing a byte array form of the .NET Framework object]

+                </data>

+        

+            There are any number of "resheader" rows that contain simple 

+            name/value pairs.

+            

+            Each data row contains a name, and value. The row also contains a 

+            type or mimetype. Type corresponds to a .NET class that support 

+            text/value conversion through the TypeConverter architecture. 

+            Classes that don't support this are serialized and stored with the 

+            mimetype set.

+                     

+            The mimetype is used for serialized objects, and tells the 

+            ResXResourceReader how to depersist the object. This is currently not 

+            extensible. For a given mimetype the value must be set accordingly:

+        

+            Note - application/x-microsoft.net.object.binary.base64 is the format 

+                   that the ResXResourceWriter will generate, however the reader can 

+                   read any of the formats listed below.

+        

+            mimetype: application/x-microsoft.net.object.binary.base64

+            value   : The object must be serialized with 

+                    : System.Serialization.Formatters.Binary.BinaryFormatter

+                    : and then encoded with base64 encoding.

+        

+            mimetype: application/x-microsoft.net.object.soap.base64

+            value   : The object must be serialized with 

+                    : System.Runtime.Serialization.Formatters.Soap.SoapFormatter

+            Microsoft ResX Schema 

+        

+            Version 1.3

+                

+            The primary goals of this format is to allow a simple XML format 

+            that is mostly human readable. The generation and parsing of the 

+            various data types are done through the TypeConverter classes 

+            associated with the data types.

+        

+            Example:

+        

+                ... ado.net/XML headers & schema ...

+                <resheader name="resmimetype">text/microsoft-resx</resheader>

+                <resheader name="version">1.3</resheader>

+                <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>

+                <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>

+                <data name="Name1">this is my long string</data>

+                <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>

+                <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">

+                    [base64 mime encoded serialized .NET Framework object]

+                </data>

+                <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">

+                    [base64 mime encoded string representing a byte array form of the .NET Framework object]

+                </data>

+        

+            There are any number of "resheader" rows that contain simple 

+            name/value pairs.

+            

+            Each data row contains a name, and value. The row also contains a 

+            type or mimetype. Type corresponds to a .NET class that support 

+            text/value conversion through the TypeConverter architecture. 

+            Classes that don't support this are serialized and stored with the 

+            mimetype set.

+                     

+            The mimetype is used for serialized objects, and tells the 

+            ResXResourceReader how to depersist the object. This is currently not 

+            extensible. For a given mimetype the value must be set accordingly:

+        

+            Note - application/x-microsoft.net.object.binary.base64 is the format 

+                   that the ResXResourceWriter will generate, however the reader can 

+                   read any of the formats listed below.

+        

+            mimetype: application/x-microsoft.net.object.binary.base64

+            value   : The object must be serialized with 

+                    : System.Serialization.Formatters.Binary.BinaryFormatter

+                    : and then encoded with base64 encoding.

+        

+            mimetype: application/x-microsoft.net.object.soap.base64

+            value   : The object must be serialized with 

+                    : System.Runtime.Serialization.Formatters.Soap.SoapFormatter

+                    : and then encoded with base64 encoding.

+            mimetype: application/x-microsoft.net.object.bytearray.base64

+            value   : The object must be serialized into a byte array 

+                    : using a System.ComponentModel.TypeConverter

+                    : and then encoded with base64 encoding.

+[assembly: AssemblyTitle("")]

+//

+//      Major Version

+//      Minor Version 

+//      Build Number

+//      Revision

+//

+// You can specify all the values or you can default the Revision and Build Numbers

+

+[assembly: AssemblyVersion("1.0.*")]

+

+//

+// In order to sign your assembly you must specify a key to use. Refer to the

+//

+// Use the attributes below to control which key is used for signing. 

+//

+// Notes: 

+//   (*) If no key is specified, the assembly is not signed.

+//   (*) KeyName refers to a key that has been installed in the Crypto Service

+//       Provider (CSP) on your machine. KeyFile refers to a file which contains

+//       a key.

+//   (*) If the KeyFile and the KeyName values are both specified, the 

+//       following processing occurs:

+//       (1) If the KeyName can be found in the CSP, that key is used.

+//       (2) If the KeyName does not exist and the KeyFile does exist, the key 

+//           in the KeyFile is installed into the CSP and used.

+//   (*) In order to create a KeyFile, you can use the sn.exe (Strong Name) utility.

+//       When specifying the KeyFile, the location of the KeyFile should be

+//       relative to the project output directory which is

+//       %Project Directory%\obj\<configuration>. For example, if your KeyFile is

+//       located in the project directory, you would specify the AssemblyKeyFile 

+//       attribute as [assembly: AssemblyKeyFile("..\\..\\mykey.snk")]

+//   (*) Delay Signing is an advanced option - see the Microsoft .NET Framework

+//       documentation for more information on this.

+	* cs0176.cs: Method has to be public for correct test
+	* cs0196.cs, cs0242.cs: Do 'return' to stop null statement warning.
+	* cs0255.cs: Add assignment to stop 'unused variable' warning.

+     Berkeley Yacc owes much to the unflagging efforts of Keith Bostic.
+His badgering kept me working on it long after I was ready to quit.
+
+     Berkeley Yacc is based on the excellent algorithm for computing LALR(1)
+lookaheads developed by Tom Pennello and Frank DeRemer.  The algorithm is
+described in their almost impenetrable article in TOPLAS 4,4.
+
+     Finally, much of the credit for the latest version must go to those
+who pointed out deficiencies of my earlier releases.  Among the most
+prolific contributors were
+
+	  Benson I. Margulies
+	  Dave Gentzel
+	  Antoine Verheijen
+	  Peter S. Housel
+	  Dale Smith
+	  Ozan Yigit
+	  John Campbell

+     The -r option has been implemented.  The -r option tells Yacc to
+put the read-only tables in y.tab.c and the code and variables in
+y.code.c.  Keith Bostic asked for this option so that :yyfix could be
+eliminated.
+
+     The -l and -t options have been implemented.  The -l option tells
+Yacc not to include #line directives in the code it produces.  The -t
+option causes debugging code to be included in the compiled parser.
+
+     The code for error recovery has been changed to implement the same
+algorithm as AT&T Yacc.  There will still be differences in the way
+error recovery works because AT&T Yacc uses more default reductions
+than Berkeley Yacc.
+
+     The environment variable TMPDIR determines the directory where
+temporary files will be created.  If TMPDIR is defined, temporary files
+will be created in the directory whose pathname is the value of TMPDIR.
+By default, temporary files are created in /tmp.
+
+     The keywords are now case-insensitive.  For example, %nonassoc,
+%NONASSOC, %NonAssoc, and %nOnAsSoC are all equivalent.
+
+     Commas and semicolons that are not part of C code are treated as
+commentary.
+
+     Line-end comments, as in BCPL, are permitted.  Line-end comments
+begin with // and end at the next end-of-line.  Line-end comments are
+permitted in C code; they are converted to C comments on output.
+
+     The form of y.output files has been changed to look more like
+those produced by AT&T Yacc.
+
+     A new kind of declaration has been added.  The form of the declaration
+is
+
+	  %ident string
+
+where string is a sequence of characters begining with a double quote
+and ending with either a double quote or the next end-of-line, whichever
+comes first.  The declaration will cause a #ident directive to be written
+near the start of the output file.
+
+     If a parser has been compiled with debugging code, that code can be
+enabled by setting an environment variable.  If the environment variable
+YYDEBUG is set to 0, debugging output is suppressed.  If it is set to 1,
+debugging output is written to standard output.

+Berkeley Yacc reflects its origins.  The reason so many routines
+use exactly six register variables is that Berkeley Yacc was
+developed on a VAX using PCC.  PCC placed at most six variables
+in registers.  I went to considerable effort to find which six
+variables most belonged in registers.  Changes in machines and
+compilers make that effort worthless, perhaps even harmful.
+
+The code contains many instances where address calculations are
+performed in particular ways to optimize the code for the VAX.

+test			removed
+yacc.1 -> jay.1		adapted
+yyfix.*			removed
+
+Types: there is a significant difference. yacc uses %union to cast the value
+stack and <tag> to select alternatives. This works for l- and r-values alike.
+jay uses Object as the value stack and <tag> to set a class. l-values must not
+be cast. $n should not be assigned to, but $$ usually is. $n is referenced,
+but $$ usually is not. Consequently jay casts $n and $<tag>$ but not $<>n
+and $$. This makes assignment to $n references to $$ kludgily possible.
+As another kludge, to prevent 'untyped' messages and to avoid unnecessary
+casts, casts to "Object" are not emitted.

+.TH JAY 1 "May 24, 1993 / July 8, 1998"
+.UC 6
+.SH NAME
+jay \- an LALR(1) parser generator for Java and C#
+.SH SYNOPSIS
+.B jay [ -tv ] [ -c ] [ -b
+.I file_prefix
+.B ] [ -V
+.I yyValue
+.B ]
+.I filename
+.B <
+.I skeleton
+.SH DESCRIPTION
+.I Jay
+reads the grammar specification in the file
+.I filename
+and generates an LR(1) parser for it.
+The parsers consist of a set of LALR(1) parsing tables and a driver routine
+from the file
+.I skeleton
+written in the Java programming language.
+.I Jay
+writes the parse tables and the driver routine to standard output.
+.PP
+The following options are available:
+.RS
+.TP
+\fB-b \fIfile_prefix\fR
+The
+.B -b
+option changes the prefix prepended to the output file names to
+the string denoted by
+.IR file_prefix.
+The default prefix is the character
+.IR y.
+.TP
+.B -c
+The
+.B -c 
+option makes jay generate C# code instead of the default Java.
+.TP
+.B -t
+The
+.B -t
+option arranges for
+debugging information to be incorporated in the compiled code.
+.TP
+.B -v
+The
+.B -v
+option causes a human-readable description of the generated parser to
+be written to the file
+.IR y.output.
+.RE
+.PP
+If the environment variable TMPDIR is set, the string denoted by
+TMPDIR will be used as the name of the directory where the temporary
+files are created.
+.SH FILES
+.IR skeleton
+.br
+.IR y.output
+.br
+.IR /tmp/yacc.aXXXXXX
+.br
+.IR /tmp/yacc.tXXXXXX
+.br
+.IR /tmp/yacc.uXXXXXX
+.SH DIAGNOSTICS
+If there are rules that are never reduced, the number of such rules is
+reported on standard error.
+If there are any LALR(1) conflicts, the number of conflicts is reported
+on standard error.
+.SH HISTORY
+.I Jay
+is derived from Berkeley
+.I yacc .
+Input conventions closely follow those of
+.I yacc ;
+for details,
+consult the parser
+.I skeleton
+file and the commented example included with the sources.

+2002-07-25  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs: Rename --resource to --linkres, because that is what
+	we do currently, we dont support --resource yet.
+
+	* cs-tokenizer.cs: Fix test for reporting endif mismatches.
+
+2002-07-25  Martin Baulig  <martin@gnome.org>
+
+	* class.cs (MethodData): New public class.  This is a `method builder'
+	class for a method or one accessor of a Property/Indexer/Event.
+	(MethodData.GetMethodFlags): Moved here from MemberBase.
+	(MethodData.ApplyAttributes): Likewise.
+	(MethodData.ApplyObsoleteAttribute): Likewise.
+	(MethodData.ApplyConditionalAttribute): Likewise.
+	(MethodData.ApplyDllImportAttribute): Likewise.
+	(MethodData.CheckAbstractAndExternal): Likewise.
+	(MethodData.Define): Formerly knows as MemberBase.DefineMethod().
+	(MethodData.Emit): Formerly known as Method.Emit().
+	(MemberBase): Moved everything which was specific to a single
+	accessor/method to MethodData.
+	(Method): Create a new MethodData and call Define() and Emit() on it.
+	(Property, Indexer, Event): Create a new MethodData objects for each
+	accessor and call Define() and Emit() on them.
+
+2002-07-25  Martin Baulig  <martin@gnome.org>
+
+	Made MethodCore derive from MemberBase to reuse the code from there.
+	MemberBase now also checks for attributes.
+
+	* class.cs (MethodCore): Derive from MemberBase, not MemberCore.
+	(MemberBase.GetMethodFlags): Moved here from class Method and marked
+	as virtual.
+	(MemberBase.DefineAccessor): Renamed to DefineMethod(), added
+	`CallingConventions cc' and `Attributes opt_attrs' arguments.
+	(MemberBase.ApplyAttributes): New virtual method; applies the
+	attributes to a method or accessor.
+	(MemberBase.ApplyObsoleteAttribute): New protected virtual method.
+	(MemberBase.ApplyConditionalAttribute): Likewise.
+	(MemberBase.ApplyDllImportAttribute): Likewise.
+	(MemberBase.CheckAbstractAndExternal): Likewise.
+	(MethodCore.ParameterTypes): This is now a property instead of a
+	method, it's initialized from DoDefineParameters().
+	(MethodCore.ParameterInfo): Removed the set accessor.
+	(MethodCore.DoDefineParameters): New protected virtual method to
+	initialize ParameterTypes and ParameterInfo.
+	(Method.GetReturnType): We can now simply return the MemberType.
+	(Method.GetMethodFlags): Override the MemberBase version and add
+	the conditional flags.
+	(Method.CheckBase): Moved some code from Define() here, call
+	DoDefineParameters() here.
+	(Method.Define): Use DoDefine() and DefineMethod() from MemberBase
+	here to avoid some larger code duplication.
+	(Property.Emit, Indexer.Emit): Call CheckAbstractAndExternal() to
+	ensure that abstract and external accessors don't declare a body.
+
+	* attribute.cs (Attribute.GetValidPieces): Make this actually work:
+	`System.Attribute.GetCustomAttributes (attr.Type)' does a recursive
+	lookup in the attribute's parent classes, so we need to abort as soon
+	as we found the first match.
+	(Attribute.Obsolete_GetObsoleteMessage): Return the empty string if
+	the attribute has no arguments.
+
+	* typemanager.cs (TypeManager.AddMethod): Now takes a MemberBase instead
+	of a Method.
+
+2002-07-24  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* cs-parser.jay: reverted previous patch.
+
+2002-07-24  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* cs-parser.jay: fixed bug #22119.
+
+2002-07-24  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* attribute.cs: fixed compilation. The error was:
+	"attribute.cs(571,17): error CS0177: The out parameter 'is_error' must 
+	be assigned to before control leaves the current method."
+	[FIXME:  Filed as bug #28186: MCS must report this error.]
+
+2002-07-25  Martin Baulig  <martin@gnome.org>
+
+	* attribute.cs (Attribute.Conditional_GetConditionName): New static
+	method to pull the condition name ouf of a Conditional attribute.
+	(Attribute.Obsolete_GetObsoleteMessage): New static method to pull
+	the obsolete message and error flag out of an Obsolete attribute.
+
+	* class.cs (Method.GetMethodFlags): New public method to get the
+	TypeManager.MethodFlags for this method.
+	(Method.ApplyConditionalAttribute, Method.ApplyObsoleteAttribute): New
+	private methods.
+	(Method.Define): Get and apply the Obsolete and Conditional attributes;
+	if we're overriding a virtual function, set the new private variable
+	`parent_method'; call the new TypeManager.AddMethod().
+
+	* typemanager.cs (TypeManager.AddMethod): New static method.  Stores
+	the MethodBuilder and the Method in a PtrHashtable.
+	(TypeManager.builder_to_method): Added for this purpose.
+	(TypeManager.MethodFlags): Added IsObsoleteError.
+	(TypeManager.GetMethodFlags): Added `Location loc' argument.  Lookup
+	Obsolete and Conditional arguments in MethodBuilders.  If we discover
+	an Obsolete attribute, emit an appropriate warning 618 / error 619 with
+	the message from the attribute.
+
+2002-07-24  Martin Baulig  <martin@gnome.org>
+
+	* cs-tokenizer.cs: Eat up trailing whitespaces and one-line comments in
+	preprocessor directives, ensure that the argument to #define/#undef is
+	exactly one identifier and that it's actually an identifier.
+
+	Some weeks ago I did a `#define DEBUG 1' myself and wondered why this
+	did not work ....
+
+2002-07-24  Martin Baulig  <martin@gnome.org>
+
+	* statement.cs (Foreach.ForeachHelperMethods): Added `Type element_type',
+	initialize it to TypeManager.object_type in the constructor.
+	(Foreach.GetEnumeratorFilter): Set `hm.element_type' to the return type
+	of the `hm.get_current' method if we're using the collection pattern.
+	(Foreach.EmitCollectionForeach): Use `hm.element_type' as the source type
+	for the explicit conversion to make it work when we're using the collection
+	pattern and the `Current' property has a different return type than `object'.
+	Fixes #27713.
+
+2002-07-24  Martin Baulig  <martin@gnome.org>
+
+	* delegate.cs (Delegate.VerifyMethod): Simply return null if the method
+	does not match, but don't report any errors.  This method is called in
+	order for all methods in a MethodGroupExpr until a matching method is
+	found, so we don't want to bail out if the first method doesn't match.
+	(NewDelegate.DoResolve): If none of the methods in the MethodGroupExpr
+	matches, report the 123.  Fixes #28070.
+
+2002-07-24  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (ArrayAccess.EmitStoreOpcode): Moved the
+	TypeManager.TypeToCoreType() to the top of the method so the
+	following equality checks will work.  Fixes #28107.
+
+2002-07-24  Martin Baulig  <martin@gnome.org>
+
+	* cfold.cs (ConstantFold.DoConstantNumericPromotions): "If either
+	operand is of type uint, and the other operand is of type sbyte,
+	short or int, the operands are converted to type long." -
+	Actually do what this comment already told us.  Fixes bug #28106,
+	added test-150.cs.
+
+2002-07-24  Martin Baulig  <martin@gnome.org>
+
+	* class.cs (MethodBase): New abstract class.  This is now a base
+	class for Property, Indexer and Event to avoid some code duplication
+	in their Define() and DefineMethods() methods.
+	(MethodBase.DoDefine, MethodBase.DefineAccessor): Provide virtual
+	generic methods for Define() and DefineMethods().
+	(FieldBase): Derive from MemberBase, not MemberCore.
+	(Property): Derive from MemberBase, not MemberCore.
+	(Property.DefineMethod): Moved all the code from this method to the
+	new MethodBase.DefineAccessor(), just call it with appropriate
+	argumetnts.
+	(Property.Define): Call the new Property.DoDefine(), this does some
+	sanity checks and we don't need to duplicate the code everywhere.
+	(Event): Derive from MemberBase, not MemberCore.
+	(Event.Define): Use the new MethodBase.DefineAccessor() to define the
+	accessors, this will also make them work with interface events.
+	(Indexer): Derive from MemberBase, not MemberCore.
+	(Indexer.DefineMethod): Removed, call MethodBase.DefineAccessor() insstead.
+	(Indexer.Define): Use the new MethodBase functions.
+
+	* interface.cs (InterfaceEvent.InterfaceEvent): Added `Location loc'
+	argument to the constructor.
+	(Interface.FindMembers): Added support for interface events.
+	(Interface.PopluateEvent): Implemented.
+
+	Added test-149.cs for this.  This also fixes bugs #26067 and #24256.
+
+2002-07-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (TypeContainer.AddMethod): Adding methods do not use IsValid,
+	but this is required to check for a method name being the same as
+	the containing class.  
+
+	Handle this now.
+
+2002-07-22  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* interface.cs: initialize variable.
+
+2002-07-23  Martin Baulig  <martin@gnome.org>
+
+	Implemented the IndexerName attribute in interfaces.
+
+	* class.cs (TypeContainer.DefineIndexers): Don't set the indexer
+	name if this is an explicit interface implementation.
+	(Indexer.InterfaceIndexerName): New public variable.  If we're
+	implementing an interface indexer, this is the IndexerName in that
+	interface.  Otherwise, it's the IndexerName.
+	(Indexer.DefineMethod): If we're implementing interface indexer,
+	set InterfaceIndexerName.  Use the new Pending.IsInterfaceIndexer
+	and Pending.ImplementIndexer methods.
+	(Indexer.Define): Also define the PropertyBuilder if we're
+	implementing an interface indexer and this is neither an explicit
+	interface implementation nor do the IndexerName match the one in
+	the interface.
+
+	* pending.cs (TypeAndMethods): Added `MethodInfo [] need_proxy'.
+	If a method is defined here, then we always need to create a proxy
+	for it.  This is used when implementing interface indexers.
+	(Pending.IsInterfaceIndexer): New public method.
+	(Pending.ImplementIndexer): New public method.
+	(Pending.InterfaceMethod): Added `MethodInfo need_proxy' argument.
+	This is used when implementing interface indexers to define a proxy
+	if necessary.
+	(Pending.VerifyPendingMethods): Look in the `need_proxy' array and
+	define a proxy if necessary.
+
+	* interface.cs (Interface.IndexerName): New public variable.
+	(Interface.PopulateIndexer): Set the IndexerName.
+	(Interface.DefineIndexers): New private method.  Populate all the
+	indexers and make sure their IndexerNames match.
+
+	* typemanager.cs (IndexerPropertyName): Added support for interface
+	indexers.
+
+2002-07-22  Martin Baulig  <martin@gnome.org>
+
+	* codegen.cs (EmitContext.HasReturnLabel): New public variable.
+	(EmitContext.EmitTopBlock): Always mark the ReturnLabel and emit a
+	ret if HasReturnLabel.
+	(EmitContext.TryCatchLevel, LoopBeginTryCatchLevel): New public
+	variables.
+
+	* statement.cs (Do.Emit, While.Emit, For.Emit, Foreach.Emit): Save
+	and set the ec.LoopBeginTryCatchLevel.
+	(Try.Emit): Increment the ec.TryCatchLevel while emitting the block.
+	(Continue.Emit): If the ec.LoopBeginTryCatchLevel is smaller than
+	the current ec.TryCatchLevel, the branch goes out of an exception
+	block.  In this case, we need to use Leave and not Br.
+
+2002-07-22  Martin Baulig  <martin@gnome.org>
+
+	* statement.cs (Try.Emit): Emit an explicit ret after the end of the
+	block unless the block does not always return or it is contained in
+	another try { ... } catch { ... } block.  Fixes bug #26506.
+	Added verify-1.cs to the test suite.
+
+2002-07-22  Martin Baulig  <martin@gnome.org>
+
+	* statement.cs (Switch.TableSwitchEmit): If we don't have a default,
+	then we do not always return.  Fixes bug #24985.
+
+2002-07-22  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (Invocation.OverloadedResolve): Do the BetterFunction()
+	lookup on a per-class level; ie. walk up the class hierarchy until we
+	found at least one applicable method, then choose the best among them.
+	Fixes bug #24463 and test-29.cs.
+
+2002-07-22  Martin Baulig  <martin@gnome.org>
+
+	* typemanager.cs (TypeManager.ArrayContainsMethod): Don't check the
+	return types of the methods.  The return type is not part of the
+	signature and we must not check it to make the `new' modifier work.
+	Fixes bug #27999, also added test-147.cs.
+	(TypeManager.TypeToCoreType): Added TypeManager.type_type.
+
+	* expression.cs (Invocation.DoResolve): Call TypeManager.TypeToCoreType()
+	on the method's return type.
+
+2002-07-21  Martin Baulig  <martin@gnome.org>
+
+	* assign.cs: Make this work if the rightmost source is a constant and
+	we need to do an implicit type conversion.  Also adding a few more tests
+	to test-38.cs which should have caught this.
+
+	* makefile.gnu: Disable debugging, there's already the mcs-mono2.exe
+	target in the makefile for this.  The makefile.gnu is primarily intended
+	for end-users who don't want to debug the compiler.
+
+2002-07-21  Martin Baulig  <martin@gnome.org>
+
+	* assign.cs: Improved the Assign class so it can now handle embedded
+	assignments (X = Y = Z = something).  As a side-effect this'll now also
+	consume less local variables.  test-38.cs now passes with MCS, added
+	a few new test cases to that test.
+
+2002-07-20  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (Binary.EmitBranchable): Emit correct unsigned branch
+	instructions.  Fixes bug #27977, also added test-146.cs.
+
+2002-07-19  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* cs-tokenizer.cs: fixed getHex ().
+
+2002-07-19  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (Invocation.EmitParams): Use TypeManager.LookupType(),
+	not Type.GetType() to lookup the array type.  This is needed when
+	we're constructing an array of a user-defined type.
+	(ArrayAccess.EmitDynamicInitializers): Only emit the Ldelema for
+	single-dimensional arrays, but also for single-dimensial arrays of
+	type decimal.
+
+2002-07-19  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (New.DoEmit): Create a new LocalTemporary each time
+	this function is called, it's not allowed to share LocalBuilders
+	among ILGenerators.
+
+2002-07-19  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (Argument.Resolve): Report an error 118 when trying
+	to pass a type as argument.
+
+2002-07-18  Martin Baulig  <martin@gnome.org>
+
+	* ecore.cs (Expression.ImplicitNumericConversion): Don't emit a
+	Conv_R_Un for the signed `long' type.
+
+2002-07-15  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (MemberAccess.DoResolve): Do not reuse the field
+	`expr' for the temporary result, as that will fail if we do
+	multiple resolves on the same expression.
+
+2002-07-05  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (SimpleNameResolve): Use ec.DeclSpace instead of
+	ec.TypeContainer for looking up aliases. 
+
+	* class.cs (TypeContainer): Remove LookupAlias from here.
+
+	* decl.cs (DeclSpace); Move here.
+
+2002-07-01  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (FindMembers): Only call filter if the constructor
+	bulider is not null.
+
+	Also handle delegates in `NestedTypes' now.  Now we will perform
+	type lookups using the standard resolution process.  This also
+	fixes a bug.
+
+	* decl.cs (DeclSpace.ResolveType): New type resolution routine.
+	This uses Expressions (the limited kind that can be parsed by the
+	tree) instead of strings.
+
+	* expression.cs (ComposedCast.ToString): Implement, used to flag
+	errors since now we have to render expressions.
+
+	(ArrayCreation): Kill FormElementType.  Use ComposedCasts in
+	FormArrayType. 
+
+	* ecore.cs (SimpleName.ToString): ditto.
+
+	* cs-parser.jay: Instead of using strings to assemble types, use
+	Expressions to assemble the type (using SimpleName, ComposedCast,
+	MemberAccess).  This should fix the type lookups in declarations,
+	because we were using a different code path for this.
+
+	* statement.cs (Block.Resolve): Continue processing statements
+	even when there is an error.
+
+2002-07-17  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Event.Define): Also remove the `remove' method from
+	the list of pending items.
+
+	* expression.cs (ParameterReference): Use ldarg.N (0..3) to
+	generate more compact code. 
+
+2002-07-17  Martin Baulig  <martin@gnome.org>
+
+	* const.cs (Const.LookupConstantValue): Add support for constant
+	`unchecked' and `checked' expressions.
+	Also adding test case test-140.cs for this.
+
+2002-07-17  Martin Baulig  <martin@gnome.org>
+
+	* statement.cs (Foreach.GetEnumeratorFilter): When compiling corlib,
+	check whether mi.ReturnType implements the IEnumerator interface; the
+	`==' and the IsAssignableFrom() will fail in this situation.
+
+2002-07-16  Ravi Pratap  <ravi@ximian.com>
+
+	* ecore.cs (SimpleName.SimpleNameResolve) : Apply Gonzalo's fix 
+	here too.
+
+2002-07-16  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* expression.cs: fixed bug #27811.
+
+2002-07-14  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (ParameterReference.AddressOf): Patch from Paolo
+	Molaro: when we are a ref, the value already contains a pointer
+	value, do not take the address of it.
+
+2002-07-14 Rafael Teixeira <rafaelteixeirabr@hotmail.com>
+	* removed mb-parser.jay and mb-tokenizer.cs
+
+Sat Jul 13 19:38:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* expression.cs: check against the building corlib void type.
+
+Sat Jul 13 19:35:58 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* ecore.cs: fix for valuetype static readonly fields: when 
+	initializing them, we need their address, not the address of a copy.
+
+Sat Jul 13 17:32:53 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* typemanager.cs: register also enum_type in corlib.
+
+Sat Jul 13 15:59:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* class.cs: allow calling this (but not base) initializers in structs.
+
+Sat Jul 13 15:12:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* ecore.cs: make sure we compare against the building base types
+	in GetTypeSize ().
+
+Sat Jul 13 15:10:32 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* typemanager.cs: fix TypeToCoreType() to handle void and object
+	(corlib gets no more typerefs after this change).
+
+2002-07-12  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (ArrayCreation.EmitArrayArguments): use
+	Conv.Ovf.U4 for unsigned and Conv.Ovf.I4 for signed.
+
+	(ArrayAccess.LoadArrayAndArguments): Use Conv_Ovf_I and
+	Conv_Ovf_I_Un for the array arguments.  Even if C# allows longs as
+	array indexes, the runtime actually forbids them.
+
+	* ecore.cs (ExpressionToArrayArgument): Move the conversion code
+	for array arguments here.
+
+	* expression.cs (EmitLoadOpcode): System.Char is a U2, use that
+	instead of the default for ValueTypes.
+
+	(New.DoEmit): Use IsValueType instead of
+	IsSubclassOf (value_type)
+	(New.DoResolve): ditto.
+	(Invocation.EmitCall): ditto.
+
+	* assign.cs (Assign): ditto.
+
+	* statement.cs (Unsafe): Ok, so I got the semantics wrong.
+	Statements *are* currently doing part of their resolution during
+	Emit.  
+
+	Expressions do always resolve during resolve, but statements are
+	only required to propagate resolution to their children.
+
+2002-07-11  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs (CSCParseOption): Finish the /r: and /lib: support.
+
+	(LoadAssembly): Do not add the dll if it is already specified
+	
+	(MainDriver): Add the System directory to the link path at the end,
+	after all the other -L arguments. 
+
+	* expression.cs (ArrayAccess.EmitLoadOpcode): I was using the
+	wrong opcode for loading bytes and bools (ldelem.i1 instead of
+	ldelem.u1) and using the opposite for sbytes.
+
+	This fixes Digger, and we can finally run it.
+
+	* driver.cs (UnixParseOption): Move the option parsing here.  
+	(CSCParseOption): Implement CSC-like parsing of options.
+
+	We now support both modes of operation, the old Unix way, and the
+	new CSC-like way.  This should help those who wanted to make cross
+	platform makefiles.
+
+	The only thing broken is that /r:, /reference: and /lib: are not
+	implemented, because I want to make those have the same semantics
+	as the CSC compiler has, and kill once and for all the confussion
+	around this.   Will be doing this tomorrow.
+
+	* statement.cs (Unsafe.Resolve): The state is checked during
+	resolve, not emit, so we have to set the flags for IsUnsfe here.
+
+2002-07-10  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (MemberAccess.ResolveMemberAccess): Since we can
+	not catch the Error_ObjectRefRequired in SimpleName (as it is
+	possible to have a class/instance variable name that later gets
+	deambiguated), we have to check this here. 	
+
+2002-07-10  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (TypeContainer.GetFieldFromEvent): Move away from here,
+	make static and put into Expression.
+
+	(Event.Define): Register the private field of the event with the 
+	TypeManager so that GetFieldFromEvent can get at it.
+
+	(TypeManager.RegisterPrivateFieldOfEvent): Implement to
+	keep track of the private field associated with an event which
+	has no accessors.
+
+	(TypeManager.GetPrivateFieldOfEvent): Implement to get at the
+	private field.
+
+	* ecore.cs (GetFieldFromEvent): RE-write to use the above methods.
+	
+2002-07-10  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (Binary.EmitBranchable): this routine emits the
+	Binary expression in a branchable context.  This basically means:
+	we need to branch somewhere, not just get the value on the stack.
+
+	This works together with Statement.EmitBoolExpression.
+
+	* statement.cs (Statement.EmitBoolExpression): Use
+	EmitBranchable. 
+
+2002-07-09  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (For): Reduce the number of jumps in loops.
+
+	(For): Implement loop inversion for the For statement.
+
+	(Break): We can be breaking out of a Try/Catch controlled section
+	(foreach might have an implicit try/catch clause), so we need to
+	use Leave instead of Br.
+
+	* ecore.cs (FieldExpr.AddressOf): Fix for test-139 (augmented
+	now).  If the instace expression supports IMemoryLocation, we use
+	the AddressOf method from the IMemoryLocation to extract the
+	address instead of emitting the instance.
+
+	This showed up with `This', as we were emitting the instance
+	always (Emit) instead of the Address of This.  Particularly
+	interesting when This is a value type, as we dont want the Emit
+	effect (which was to load the object).
+	
+2002-07-08  Miguel de Icaza  <miguel@ximian.com>
+
+	* attribute.cs: Pass the entry point to the DefinePInvokeMethod
+
+	* statement.cs (Checked): Set the CheckedState during the resolve
+	process too, as the ConvCast operations track the checked state on
+	the resolve process, and not emit.
+
+	* cs-parser.jay (namespace_member_declaration): Flag that we have
+	found a declaration when we do.  This is used to flag error 1529
+
+	* driver.cs: Report ok when we display the help only.
+
+2002-07-06  Andrew Birkett  <adb@tardis.ed.ac.uk>
+
+	* cs-tokenizer.cs (xtoken): Improve handling of string literals.
+
+2002-07-04  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-tokenizer.cs (define): We also have to track locally the
+	defines.  AllDefines is just used for the Conditional Attribute,
+	but we also need the local defines for the current source code. 
+
+2002-07-03  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (While, For, Do): These loops can exit through a
+	Break statement, use this information to tell whether the
+	statement is the last piece of code.
+
+	(Break): Flag that we break.
+
+	* codegen.cs (EmitContexts): New `Breaks' state variable.
+
+2002-07-03  Martin Baulig  <martin@gnome.org>
+
+	* class.cs (TypeContainer.MethodModifiersValid): Allow override
+	modifiers in method declarations in structs.  Otherwise, you won't
+	be able to override things like Object.Equals().
+
+2002-07-02  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Method, Property, Indexer): Do not allow the public
+	modifier to be used in explicit interface implementations.
+
+	(TypeContainer.MethodModifiersValid): Catch virtual, abstract and
+	override modifiers in method declarations in structs
+
+2002-07-02   Andrew Birkett <adb@tardis.ed.ac.uk>
+
+	* cs-tokenizer.cs (adjust_int, adjust_real): Do not abort on
+	integer or real overflow, report an error
+
+2002-07-02  Martin Baulig  <martin@gnome.org>
+
+	* typemanager.cs (TypeManager.InitCoreTypes): When compiling
+	corlib, dynamically call AssemblyBuilder.SetCorlibTypeBuilders()
+	to tell the runtime about our newly created System.Object and
+	System.ValueType types.
+
+2002-07-02  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (This): Use Stobj/Ldobj when we are a member of a
+	struct instead of Ldarg/Starg.
+
+2002-07-02  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (Indirection.Indirection): Call
+	TypeManager.TypeToCoreType() on `expr.Type.GetElementType ()'.
+
+2002-07-02  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (ArrayAccess.EmitStoreOpcode): If the type is a
+	ValueType, call TypeManager.TypeToCoreType() on it.
+	(Invocations.EmitParams): Call TypeManager.TypeToCoreType() on
+	the OpCodes.Newarr argument.
+
+2002-07-02  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (Invocation.EmitCall): When compiling corlib,
+	replace all calls to the system's System.Array type to calls to
+	the newly created one.
+
+	* typemanager.cs (TypeManager.InitCodeHelpers): Added a few more
+	System.Array methods.
+	(TypeManager.InitCoreTypes): When compiling corlib, get the methods
+	from the system's System.Array type which must be replaced.
+
+Tue Jul 2 19:05:05 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* typemanager.cs: load unverifiable_code_ctor so we can build
+	corlib using the correct type. Avoid using GetTypeCode() with
+	TypeBuilders.
+	* rootcontext.cs: uses TypeManager.unverifiable_code_ctor and
+	TypeManager.object_type to allow building corlib.
+
+Tue Jul 2 19:03:19 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* ecore.cs: handle System.Enum separately in LoadFromPtr().
+
+2002-07-01  Martin Baulig  <martin@gnome.org>
+
+	* class.cs: Make the last change actually work, we need to check
+	whether `ifaces != null' to avoid a crash.
+
+Mon Jul 1 16:15:03 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* class.cs: when we build structs without fields that implement
+	interfaces, we need to add the interfaces separately, since there is
+	no API to both set the size and add the interfaces at type creation
+	time.
+
+Mon Jul 1 14:50:47 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* expression.cs: the dimension arguments to the array constructors
+	need to be converted if they are a long.
+
+Mon Jul 1 12:26:12 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* class.cs: don't emit ldarg.0 if there is no parent constructor
+	(fixes showstopper for corlib).
+
+2002-06-29  Martin Baulig  <martin@gnome.org>
+
+	MCS now compiles corlib on GNU/Linux :-)
+
+	* attribute.cs (Attribute.ApplyAttributes): Treat Accessors like Method,
+	ie. check for MethodImplOptions.InternalCall.
+
+	* class.cs (TypeContainer.DefineType): When compiling corlib, both parent
+	and TypeManager.attribute_type are null, so we must explicitly check
+	whether parent is not null to find out whether it's an attribute type.
+	(Property.Emit): Always call Attribute.ApplyAttributes() on the GetBuilder
+	and SetBuilder, not only if the property is neither abstract nor external.
+	This is necessary to set the MethodImplOptions on the accessor methods.
+	(Indexer.Emit): Call Attribute.ApplyAttributes() on the GetBuilder and
+	SetBuilder, see Property.Emit().
+
+	* rootcontext.cs (RootContext.PopulateTypes): When compiling corlib, don't
+	populate "System.Object", "System.ValueType" and "System.Attribute" since
+	they've already been populated from BootCorlib_PopulateCoreTypes().
+
+2002-06-29  Martin Baulig  <martin@gnome.org>
+
+	* ecore.cs (Expression.ImplicitReferenceConversionExists): If expr
+	is the NullLiteral, we also need to make sure that target_type is not
+	an enum type.	
+
+2002-06-29  Martin Baulig  <martin@gnome.org>
+
+	* rootcontext.cs (RootContext.ResolveCore): We must initialize
+	`TypeManager.multicast_delegate_type' and `TypeManager.delegate_type'
+	before calling BootstrapCorlib_ResolveDelegate ().
+
+2002-06-27  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* statement.cs: fixed build-breaker. All tests passed ok.
+
+2002-06-27  Martin Baulig  <martin@gnome.org>
+
+	* typemanager.cs (TypeManager.VerifyUnManaged): Added explicit check
+	for System.Decimal when compiling corlib.
+
+2002-06-27  Martin Baulig  <martin@gnome.org>
+
+	* statement.cs (Switch.TableSwitchEmit): Make this work with empty
+	switch blocks which contain nothing but a default clause.
+
+2002-06-26  Andrew  <adb@tardis.ed.ac.uk>
+
+       * ../errors/cs1501-3.cs: Added new test for struct ctr typechecks.
+
+2002-06-27  Martin Baulig  <martin@gnome.org>
+
+	* ecore.cs (PropertyExpr.PropertyExpr): Call
+	TypeManager.TypeToCoreType() on the `pi.PropertyType'.
+
+	* typemanager.cs (TypeManager.TypeToCoreType): Return if the type
+	is already a TypeBuilder.
+
+2002-06-27  Martin Baulig  <martin@gnome.org>
+
+	* ecore.cs (Expression.ImplicitReferenceConversionExists): Use
+	`target_type == TypeManager.array_type', not IsAssignableFrom() in
+	the "from an array-type to System.Array" case.  This makes it work
+	when compiling corlib.
+
+2002-06-27  Martin Baulig  <martin@gnome.org>
+
+	* ecore.cs (Expression.SimpleNameResolve): If the expression is a
+	non-static PropertyExpr, set its InstanceExpression.  This makes
+	the `ICollection.Count' property work in System/Array.cs.
+
+2002-06-25  Andrew Birkett  <adb@tardis.ed.ac.uk>
+
+	* driver.cs: Made error handling more consistent.  Errors now
+	tracked by Report class, so many methods which used to return int
+	now return void.  Main() now prints success/failure and 
+	errors/warnings message.
+
+	Renamed '--probe' compiler argument to '--expect-error'.  Removed
+	the magic number return values (123 and 124).  Now, if the
+	expected error occurs, the compiler exits with success (exit value
+	0).  If the compilation completes without seeing that particular
+	error, the compiler exits with failure (exit value 1).  The
+	makefile in mcs/errors has been changed to handle the new behaviour.
+
+	* report.cs: Made 'expected error' number a property and renamed
+	it from 'Probe' to 'ExpectedError'.
+
+	* genericparser.cs: Removed error handling support, since it is
+	now all done by Report class.
+
+	* cs-parser.jay, mb-parser.jay: Errors are tracked by Report
+	class, so parse() no longer returns an int.
+
+	* namespace.cs: Use Report.Error instead of GenericParser.error
+
+2002-06-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (TypeContainer.AddMethod, TypeContainer.AddIndexer,
+	TypeContainer.AddOperator): At the front of the list put the
+	explicit implementations, so they get resolved/defined first. 
+
+2002-06-21  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (TypeContainer.VerifyImplements): Verifies that a given
+	interface type is implemented by this TypeContainer.  Used during
+	explicit interface implementation.
+
+	(Property.Define, Indexer.Define, Method.Define): Validate that
+	the given interface in the explicit implementation is one of the
+	base classes for the containing type.
+
+	Also if we are explicitly implementing an interface, but there is
+	no match in the pending implementation table, report an error.
+
+	(Property.Define): Only define the property if we are
+	not explicitly implementing a property from an interface.  Use the
+	correct name also for those properties (the same CSC uses,
+	although that is really not needed).
+	
+	(Property.Emit): Do not emit attributes for explicitly implemented
+	properties, as there is no TypeBuilder.
+
+	(Indexer.Emit): ditto.
+
+	Hiding then means that we do not really *implement* a pending
+	implementation, which makes code fail.
+
+2002-06-22  Martin Baulig  <martin@gnome.org>
+
+	* ecore.cs (Expression.Constantify): Call TypeManager.TypeToCoreType() on
+	the return value of Object.GetType().  [FIXME: we need to do this whenever
+	we get a type back from the reflection library].
+
+Fri Jun 21 13:37:57 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* typemanager.cs: make ExpandInterfaces() slip duplicated interfaces.
+
+2002-06-20  Miguel de Icaza  <miguel@ximian.com>
+
+	* attribute.cs: Return null if we can not look up the type.
+
+	* class.cs (TypeContainer.GetClassBases): Use ExpandInterfaces on
+	the interface types found.
+
+	* interface.cs (Interface.GetInterfaceBases): Use ExpandInterfaces on the
+	interface types found.
+
+	* typemanager.cs (GetInterfaces): Make this routine returns alll
+	the interfaces and work around the lame differences between
+	System.Type and System.Reflection.Emit.TypeBuilder in the results
+	result for GetInterfaces.
+	
+	(ExpandInterfaces): Given an array of interface types, expand and
+	eliminate repeated ocurrences of an interface.  This expands in
+	context like: IA; IB : IA; IC : IA, IB; the interface "IC" to
+	be IA, IB, IC.
+	
+2002-06-21  Martin Baulig  <martin@gnome.org>
+
+	* typemanager.cs (TypeManager.EnumToUnderlying): It's now safe to call this function
+	on System.Enum.
+
+2002-06-21  Martin Baulig  <martin@gnome.org>
+
+	* typemanager.cs (TypeManager.TypeToCoreType): New function.  When compiling corlib
+	and called with one of the core types, return the corresponding typebuilder for
+	that type.
+
+	* expression.cs (ArrayAccess.DoResolve): Call TypeManager.TypeToCoreType() on the
+	element type.
+
+2002-06-21  Martin Baulig  <martin@gnome.org>
+
+	* ecore.cs (Expression.ExplicitReferenceConversionExists): Use
+	`target_type.IsArray' instead of `target_type.IsSubclassOf (TypeManager.array_type)'.
+	(Expression.ConvertReferenceExplicit): Likewise.
+
+	* expression.cs (ElementAccess.DoResolve): Likewise.
+	(ElementAccess.DoResolveLValue): Likewise.
+
+2002-06-10  Martin Baulig  <martin@gnome.org>
+
+	* interface.cs (Interface.PopulateIndexer): When creating the setter, we need to
+	add the "value" parameter to the parameter list.
+
+	* statement.cs (Fixed.Emit): Pass the return value of the child block's Emit()
+	to our caller.
+
+2002-06-19  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (ArrayCreation.ExpressionToArrayArgument): Convert
+	the argument to an int, uint, long or ulong, per the spec.  Also
+	catch negative constants in array creation.
+
+Thu Jun 20 17:56:48 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* class.cs: do not allow the same interface to appear twice in
+	the definition list.
+
+Wed Jun 19 22:33:37 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* ecore.cs: don't use ldlen with System.Array.
+
+Wed Jun 19 20:57:40 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* ecore.cs: stobj requires a type argument. Handle indirect stores on enums.
+
+Wed Jun 19 20:17:59 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* modifiers.cs: produce correct field attributes for protected
+	internal. Easy fix so miguel can work on ther harder stuff:-)
+
+2002-06-18  Miguel de Icaza  <miguel@ximian.com>
+
+	* pending.cs: New file.  Move the code from class.cs here.
+	Support clearning the pending flag for all methods (when not doing
+	explicit interface implementation).
+
+Tue Jun 18 10:36:22 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* rootcontext.cs: added a couple more types needed to bootstrap.
+
+2002-06-17  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs (GetConstructor): Use DeclaredOnly to look the
+	constructor in the type, instead of any constructor in the type
+	hierarchy.  Thanks to Paolo for finding this bug (it showed up as
+	a bug in the Mono runtime when applying the params attribute). 
+
+2002-06-16  Rafael Teixeira  <rafaelteixeirabr@hotmail.com>
+	* changed namespace.cs to use "GenericParser.error(...)" instead of "CSharpParser.error(...)"
+
+2002-06-14  Rachel Hestilow  <hestilow@ximian.com>
+
+	* expression.cs (Unary.ResolveOperator): Use TypeManager
+	to resolve the type.
+	
+2002-06-13  Ravi Pratap  <ravi@ximian.com>
+
+	* cs-parser.jay (enum_member_declaration): Pass in the attributes
+	attached.
+
+	* enum.cs (AddEnumMember): Add support to store the attributes associated 
+	with each member too.
+
+	* attribute.cs (CheckAttribute, ApplyAttributes): Update to handle
+	field builders too - this takes care of the enum member case.
+
+2002-06-10  Rachel Hestilow  <hestilow@ximian.com>
+
+	* typemanager.cs (TypeManager.VerifyUnManaged): Allow
+	address-of operator on both value types and pointers.
+	
+2002-06-10  Martin Baulig  <martin@gnome.org>
+
+	* interface.cs (Interface.PopulateIndexer): Add the indexer's
+	PropertyBuilder to the `property_builders' list.
+
+	* expression.cs (Indexers.GetIndexersForTypeOrInterface): New private method.
+	(Indexers.GetIndexersForType): Call GetIndexersForTypeOrInterface() on the
+	`lookup_type' and all its interfaces.  Unfortunately, Type.FindMembers() won't
+	find any indexers which are inherited from an interface.
+
+2002-06-09  Martin Baulig  <martin@gnome.org>
+
+	* const.cs (Const.LookupConstantValue): Convert `Expr' to a literal of
+	the same type as the constant if necessary.  There's also a test-130.cs
+	for this.
+
+	* enum.cs (Enum.ChangeEnumType): Moved to typemanager.cs and made public.
+
+	* typemanager.cs (TypeManager.ChangeType): Previously known as
+	Enum.ChangeEnumType().
+
+2002-06-09  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (Cast.TryReduce): Added support for consts.
+
+2002-06-08  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (Accessor): Hold attributes information so we can pass
+	it along.
+
+	* cs-parser.jay (get_accessor_declaration, set_accessor_declaration):
+	Modify to pass in attributes attached to the methods.
+
+	(add_accessor_declaration, remove_accessor_declaration): Ditto.
+
+	* attribute.cs (ApplyAttributes, CheckAttribute): Update accordingly
+	to handle the Accessor kind :-)
+
+	* class.cs (Property.Emit, Event.Emit): Apply attributes to the accessors
+	
+2002-06-08  Martin Baulig  <martin@gnome.org>
+
+	* expression.cs (Unary.TryReduceNegative): Added support for
+	ULongConstants.
+
+2002-06-08  Martin Baulig  <martin@gnome.org>
+
+	* enum.cs (Enum.LookupEnumValue): Don't report an error if the
+	name can't be found in the `defined_names' - the caller will do a
+	MemberLookup in this case and thus find methods in System.Enum
+	such as Enum.IsDefined().
+
+2002-06-08  Martin Baulig  <martin@gnome.org>
+
+	* enum.cs (Enum.ChangeEnumType): This is a custom version of
+	Convert.ChangeType() which works with TypeBuilder created types.
+	(Enum.LookupEnumValue, Enum.Define): Use it here.
+
+	* class.cs (TypeContainer.RegisterRequiredImplementations): Added
+	`TypeBuilder.BaseType != null' check.
+	(TypeContainer.FindMembers): Only lookup parent members if we
+	actually have a parent.
+	(Method.EmitDestructor): Added `ec.ContainerType.BaseType != null' check.
+	(ConstructorInitializer.Resolve): Likewise.
+
+	* interface.cs (Interface.FindMembers): Added
+	`TypeBuilder.BaseType != null' check.
+
+	* rootcontext.cs (RootContext.ResolveCore): Added
+	"System.Runtime.CompilerServices.IndexerNameAttribute" to
+	classes_second_stage.
+
+	* typemanager.cs (TypeManager.InitCoreTypes): Don't initialize
+	debug_type and trace_type when compiling with --nostdlib.	
+
+2002-06-07  Martin Baulig  <martin@gnome.org>
+
+	* class.cs (TypeContainer): Added `have_nonstatic_fields' field.
+	(AddField): Set it to true when adding a non-static field.
+	(DefineType): Use `have_nonstatic_fields' to find out whether we
+	have non-static fields, not `Fields != null'.
+
+2002-06-02  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (SimpleNameResolve): Removed simple bug (we were
+	dereferencing a null on the static-field code path)
+
+2002-05-30  Martin Baulig  <martin@gnome.org>
+
+	* codegen.cs (InitMonoSymbolWriter): Added `string[] args' argument
+	to take command line arguments.  Use reflection to call the new
+	custom `Initialize' function on the symbol writer and pass it the
+	command line arguments.
+
+	* driver.cs (--debug-args): New command line argument to pass command
+	line arguments to the symbol writer.
+
+2002-05-28  Miguel de Icaza  <miguel@ximian.com>
+
+	* assign.cs (DoResolve): Forgot to do the implicit conversion to
+	the target type for indexers and properties.  Thanks to Joe for
+	catching this.
+
+2002-05-27  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs (MethodFlags): returns the method flags
+	(Obsolete/ShouldIgnore) that control warning emission and whether
+	the invocation should be made, or ignored. 
+
+	* expression.cs (Invocation.Emit): Remove previous hack, we should
+	not do this on matching a base type, we should do this based on an attribute
+
+	Only emit calls to System.Diagnostics.Debug and
+	System.Diagnostics.Trace if the TRACE and DEBUG defines are passed
+	on the command line.
+
+	* rootcontext.cs: Global settings for tracing and debugging.
+
+	* cs-tokenizer.cs (define): New utility function to track
+	defines.   Set the global settings for TRACE and DEBUG if found.
+
+2002-05-25  Ravi Pratap  <ravi@ximian.com>
+
+	* interface.cs (Populate*): Pass in the TypeContainer as well as
+	the DeclSpace as parameters so that we can create EmitContexts and
+	then use that to apply attributes etc.
+
+	(PopulateMethod, PopulateEvent, PopulateProperty)
+	(PopulateIndexer): Apply attributes everywhere.
+
+	* attribute.cs (CheckAttribute): Include InterfaceMethod, InterfaceEvent
+	etc.
+
+	(ApplyAttributes): Update accordingly.
+
+	We now apply interface attributes for all members too.
+
+2002-05-26  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Indexer.Define); Correctly check if we are explicit
+	implementation (instead of checking the Name for a ".", we
+	directly look up if the InterfaceType was specified).
+
+	Delay the creation of the PropertyBuilder.
+
+	Only create the PropertyBuilder if we are not an explicit
+	interface implementation.   This means that explicit interface
+	implementation members do not participate in regular function
+	lookups, and hence fixes another major ambiguity problem in
+	overload resolution (that was the visible effect).
+
+	(DefineMethod): Return whether we are doing an interface
+	implementation. 
+	
+	* typemanager.cs: Temporary hack until we get attributes in
+	interfaces (Ravi is working on that) and we get IndexerName
+	support in interfaces.
+
+	* interface.cs: Register the indexers as properties.
+
+	* attribute.cs (Attribute.Resolve): Catch the error, and emit a
+	warning, I have verified that this is a bug in the .NET runtime
+	(JavaScript suffers of the same problem).
+
+	* typemanager.cs (MemberLookup): When looking up members for
+	interfaces, the parent of an interface is the implicit
+	System.Object (so we succeed in searches of Object methods in an
+	interface method invocation.  Example:  IEnumerable x;  x.ToString
+	()) 
+
+2002-05-25  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Event): Events should also register if they do
+	implement the methods that an interface requires.
+
+	* typemanager.cs (MemberLookup); use the new GetInterfaces
+	method. 
+
+	(GetInterfaces): The code used to lookup interfaces for a type is
+	used in more than one place, factor it here. 
+
+	* driver.cs: Track the errors at the bottom of the file, we kept
+	on going.
+
+	* delegate.cs (NewDelegate.Emit): We have to emit a null as the
+	instance if the method we are calling is static!
+
+2002-05-24  Miguel de Icaza  <miguel@ximian.com>
+
+	* attribute.cs (ApplyAttributes): Make this function filter out
+	the IndexerName attribute (as that attribute in reality is never
+	applied) and return the string constant for the IndexerName
+	attribute. 
+
+	* class.cs (TypeContainer.Emit): Validate that all the indexers
+	have the same IndexerName attribute, and if so, set the
+	DefaultName attribute on the class. 
+
+	* typemanager.cs: The return value might contain other stuff (not
+	only methods).  For instance, consider a method with an "Item"
+	property and an Item method.
+
+	* class.cs: If there is a problem with the parameter types,
+	return. 
+
+2002-05-24  Ravi Pratap  <ravi@ximian.com>
+
+	* ecore.cs (ImplicitConversionExists): Wrapper function which also
+	looks at user defined conversion after making a call to 
+	StandardConversionExists - we need this for overload resolution.
+
+	* expression.cs : Update accordingly the various method calls.
+
+	This fixes 2 bugs filed against implicit user defined conversions 
+
+2002-05-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs: Track the result of the assignment.
+
+2002-05-21  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (MemberAccess): Improved error reporting for
+	inaccessible members.
+
+2002-05-22  Martin Baulig  <martin@gnome.org>
+
+	* makefile (mcs-mono2.exe): New target.  This is mcs compiled with
+	itself with debugging support.
+
+2002-05-22  Martin Baulig  <martin@gnome.org>
+
+	* typemanager.cs ("System.Runtime.InteropServices.StructLayoutAttribute"):
+	Removed, this isn't needed anymore.
+
+2002-05-20  Martin Baulig  <martin@gnome.org>
+
+	* typemanager.cs (InitEnumUnderlyingTypes): "System.Char" can't
+	be underlying type for an enum.
+
+2002-05-20  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs (InitEnumUnderlyingTypes): New helper function
+	that splits out the loading of just the core types.
+
+	* rootcontext.cs (ResolveCore): Split the struct resolution in
+	two, so we can load the enumeration underlying types before any
+	enums are used.
+
+	* expression.cs (Is): Bandaid until we fix properly Switch (see
+	bug #24985 for details).
+
+	* typemanager.cs (ImplementsInterface): The hashtable will contain
+	a null if there are no interfaces implemented.
+
+2002-05-18  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay (indexer_declarator): It is fine to have array
+	parameters
+
+2002-05-17  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs: (RegisterBuilder): New function used to register
+	TypeBuilders that implement interfaces.  Since
+	TypeBuilder.GetInterfaces (as usual) does not work with lame
+	Reflection.Emit. 
+	(AddUserType): register interfaces.
+
+	(ImplementsInterface): Use the builder_to_ifaces hash if we are
+	dealing with TypeBuilder.  Also, arrays are showing up as
+	SymbolTypes, which are not TypeBuilders, but whose GetInterfaces
+	methods can not be invoked on them!
+
+	* ecore.cs (ExplicitReferenceConversionExists): Made public.
+	(ImplicitReferenceConversionExists): Split out from
+	StandardConversionExists. 
+
+	* expression.cs (As): We were only implementing one of the three
+	cases for the as operator.  We now implement them all.
+	(Is): Implement the various other cases for Is as well.
+
+	* typemanager.cs (CACHE): New define used to control if we want or
+	not the FindMembers cache.  Seems to have a negative impact on
+	performance currently
+
+	(MemberLookup): Nested types have full acess to
+	enclosing type members
+
+	Remove code that coped with instance/static returns for events, we
+	now catch this in RealFindMembers.
+
+	(RealFindMembers): only perform static lookup if the instance
+	lookup did not return a type or an event.  
+
+2002-05-17  Miguel de Icaza  <miguel@ximian.com>
+
+	* assign.cs (CompoundAssign): We pass more semantic information
+	now to Compound Assignments than we did before: now we have all
+	the information at hand, and now we resolve the target *before* we
+	do the expression expansion, which allows the "CacheValue" method
+	to have the effect we intended (before, a [x] += 1 would generate
+	two differen ArrayAccess expressions from the ElementAccess,
+	during the resolution process).
+
+	(CompoundAssign.DoResolve): Resolve target and original_source here.
+
+2002-05-16  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (ArrayAccess): dropped debugging information. 
+
+	* typemanager.cs: Small bug fix: I was always returning i_members,
+	instead of one of i_members or s_members (depending on which had
+	the content).
+
+	* assign.cs (IAssignMethod.CacheTemporaries): New method.  This
+	method is invoked before any code generation takes place, and it
+	is a mechanism to inform that the expression will be invoked more
+	than once, and that the method should use temporary values to
+	avoid having side effects
+
+	(Assign.Emit): Call CacheTemporaries in the IAssignMethod.
+	
+	* ecore.cs (Expression.CacheTemporaries): Provide empty default
+	implementation.
+
+	* expression.cs (Indirection, ArrayAccess): Add support for
+	CacheTemporaries in these two bad boys. 
+
+	* ecore.cs (LoadFromPtr): figure out on our own if we need to use
+	ldobj or ldind_ref.  
+	(StoreFromPtr): Handle stobj as well.
+
+	* expression.cs (UnaryMutator): Share more code.
+	
+	* typemanager.cs (FindMembers): Thanks to Paolo for tracking this
+	down: I was not tracking the Filter function as well, which
+	was affecting the results of the cache.
+
+2002-05-15  Miguel de Icaza  <miguel@ximian.com>
+
+	* attribute.cs: Remove the hack to handle the CharSet property on
+	StructLayouts. 
+
+2002-05-14  Miguel de Icaza  <miguel@ximian.com>
+
+	* attribute.cs (DoResolve): More uglyness, we now only try to
+	resolve the attribute partially, to extract the CharSet
+	information (only if we are a StructLayout attribute).  Otherwise 
+
+	(GetExtraTypeInfo): Add some code to conditionally kill in the
+	future this.   I am more and more convinced that the .NET
+	framework has special code to handle the attribute setting on
+	certain elements.
+
+	* expression.cs (IsParamsMethodApplicable): Revert my previous
+	foreach change here, it was wrong.
+
+2002-05-13  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-tokenizer.cs: (pp_primary): Eat the ')' at the end.
+	(pp_expr): do not abort on unknown input, just return.
+	(eval): abort if there are pending chars.
+
+	* attribute.cs (Attribute.Resolve): Positional parameters are
+	optional.  Deal with that case.
+
+	* class.cs (DefineType): Call Attribute.GetExtraTypeInfo to fetch
+	the Ansi/Unicode/Auto information for the type.
+
+	(TypeContainer.DefineType): instantiate the EmitContext here, as
+	we will be using it during the type definition (to resolve
+	attributes) and during the emit phase.
+
+	* attribute.cs (Attribute.GetExtraTypeInfo): This routine is used
+	to pull type information out of the attributes
+
+	(Attribute.Resolve): track the constructor builder, and allow for
+	multiple invocations (structs and classes will use this).
+
+	* ecore.cs (MemberLookupFinal): new version with all the
+	parameters customizable.
+
+	* expression.cs (New.DoResolve): Use MemberLookupFinal to locate
+	constructors.  Return if the result value is null (as the error
+	would have been flagged already by MemberLookupFinal)
+
+	Do not allow instances of abstract classes or interfaces to be
+	created.
+	
+	* class.cs: (MethodSignature.InheritableMemberSignatureCompare):
+	We have to compare the assembly property here when dealing with
+	FamANDAssem and Assembly access modifiers, because we might be
+	creating an assembly from *modules* (that means that we are not
+	getting TypeBuilders for types defined in other modules that are
+	part of this assembly).
+
+	(Method.Emit): If the method is marked abstract and has a body,
+	emit an error. 
+
+	(TypeContainer.DefineMembers): If both the defined member and the
+	parent name match are methods, then do not emit any warnings: let
+	the Method.Define routine take care of flagging warnings.  But if
+	there is a mismatch (method overrides something else, or method is
+	overriwritten by something, then emit warning).
+
+	(MethodSignature.MemberSignatureCompare): If the sig.ret_type is
+	set to null, this means `do not check for the return type on the
+	signature'. 
+
+	(Method.Define): set the return type for the method signature to
+	null, so that we get methods with the same name and parameters and
+	different return types.  This is used to flag warning 114 (you are
+	hiding a method, and you probably want to use the new/override
+	keywords instead).
+
+	* typemanager.cs (MemberLookup): Implemented proper access
+	control, closing a long standing set of bug reports.  The problem
+	was that the Framework only has two bits: Public and NonPublic,
+	and NonPublic includes private and protected methods, but we need
+	to enforce the FamANDAssem, FamOrAssem and Family. 
+
+2002-05-11  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (GotoCase): Return true: Ammounts to giving up
+	knowledge on whether we return or not, and letting the other case
+	be responsible for it.
+
+2002-05-10  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs: Do not load directories for each file processed, only
+	do it if there is a pattern.
+
+	* ecore.cs: Report readonly assigns here as well, as we might have
+	been resolved only by MemberAccess.
+
+	(SimpleName.SimpleNameResolve): Also be useful for LValue
+	resolution.   We need this to propagate assign to local readonly variables
+
+	* typemanager.cs: Use a ptrhashtable for the criteria, because we
+	do not want to reuse potential criteria memory.
+
+	* class.cs (MyEventBuilder): Set reflected_type;
+
+	* ecore.cs (Constantify): Added support for constifying bools.
+
+	(RootContext.LookupType): Added a cache for values looked up in
+	the declaration space.
+
+	* typemanager.cs (FindMembers): Now is a front-end to
+	RealFindMembers, and provides a two-level hashtable-based cache to
+	the request.  
+
+	15% performance improvement: from 22.5 to 19.2 seconds.
+
+	* expression.cs (IsParamsMethodApplicable): use foreach.
+	(Invocation.DoResolve): ditto.
+	(New.DoResolve): ditto.
+	(ArrayCreation.DoResolve): ditto.
+
+	* ecore.cs (FindMostEncompassingType): use foreach.
+
+	* delegate.cs (NewDelegate.DoResolve): Use foreach
+
+	* ecore.cs (Expression.FindMostSpecificSource): Use foreach.
+	(RemoveMethods): use foreach.
+
+	* expression.cs (Invocation.MakeUnionSet): Optimization: Use two
+	nested foreach statements instead of for, and also break out of
+	the inner loop once a match is found.
+	
+	(Invocation.OverloadResolve): Use foreach, simplify the code. 
+
+2002-05-08  Miguel de Icaza  <miguel@ximian.com>
+
+	* cfold.cs (BinaryFold): During an enumeration evaluation context,
+	we actually unwrap the expression to allow for extra information
+	to be extracted. 
+
+	* expression.cs: Use Shr_Un on unsigned operations. 
+
+2002-05-08  Ravi Pratap  <ravi@ximian.com>
+
+	* ecore.cs (FindMostEncompass*): Fix trivial bug where the set of 
+	applicable operators was not being considered correctly. This closes
+	the bug Miguel reported.
+
+Wed May 8 16:40:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* attribute.cs: check that the type derives from System.Attribute
+	and report the correct error in that case (moved the duplicate code to
+	its own method, too).
+
+Wed May 8 11:50:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* attribute.cs: lookup attribute type name as the spec says: first the
+	bare attribute name and then name + "Attribute" (nant compiles with
+	mcs after this fix).
+
+2002-05-07  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (Unary.TryReduceNegative): Ah!  Tricky!  Tricky!
+	Because of the way we parse things, we should try to see if a
+	UIntConstant can fit in an integer.
+
+2002-05-07  Ravi Pratap  <ravi@ximian.com>
+
+	* ecore.cs (GetConversionOperators): Do not pick up op_True operators
+	when we are in an explicit context.
+
+	(ConvertReferenceExplicit): When converting from Iface type S to Class
+	T make sure the rules are implemented as an OR.
+
+	* parameter.cs (ParameterType): Make it a property for now although the
+	purpose really isn't anything immediate.
+	
+	* expression.cs (Is*Applicable): Do better checking on the parameter type
+	of a ref/out parameter. The ones from the system assemblies are already 
+	marked with the correct type so we don't need to do any correction.
+
+	* ecore.cs (StandardConversionExists): Conversion from Interface types to 
+	the object type is standard too so include that.
+
+2002-05-06  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (StandardConversionExists): Augment with missing code:
+	deal with IntConstant, LongConstants and Enumerations.
+
+	* assign.cs: Report the error, instead of failing silently
+
+	* rootcontext.cs (AddGlobalAttributes): Track attributes on the
+	typecontainer that they are declared, because the
+	typecontainer/namespace will have the list of using clauses that
+	need to be applied.
+
+	Assembly Attributes were escaping the normal registration
+	mechanism. 
+
+	(EmitCode): Apply attributes within an EmitContext that represents
+	the container they were declared on.
+	
+	* cs-parser.jay: Track bases for structs.  How did I get this wrong?
+
+2002-05-06  Ravi Pratap  <ravi@ximian.com>
+
+	* ecore.cs (FindMostEncompassingType, FindMostEncompassedType):
+	Revamp completely - make much cleaner as we now operate only
+	on a set of Types.
+
+	(FindMostSpecificSource, FindMostSpecificTarget): New methods
+	to implement the logic detailed in the spec more correctly.
+
+	(UserDefinedConversion): Update accordingly.
+
+2002-05-06  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs: Return flow analysis information up.
+
+	* cs-tokenizer.cs (adjust_real): Share code between LITERAL_DOUBLE
+	and the default.
+
+	(token): Do not consume an extra character before calling
+	decimal_digits.
+
+2002-05-06  Piers Haken	<piersh@friskit.com>
+
+	* cs-parser.jay: add 'override' attribute to System.Object.Finalize
+
+2002-05-06  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Constructor.Emit): Set the IsStatic flag in the
+	EmitContext during the instance constructor initializer
+	resolution, to stop access to instance variables.
+
+	This is mandated by the spec, last paragraph of the `constructor
+	initializers' section. 
+
+2002-05-05  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay, class.cs (Accessor): new class used to represent
+	an accessor (get or set).  In the past we used `null' to represent
+	a missing accessor.  But this is ambiguous because there was no
+	way to tell in abstract indexers/properties if one of them was
+	specified.
+
+	Now there is a way of addressing that.
+
+	* expression.cs (Indexers.GetIndexersForType): Use TypeManager.MemberLookup
+	instead of FindMembers.
+
+	* class.cs (TypeContainer.EmitFieldInitializer): Do not typecast
+	the result of Assign.Resolve as Assign, but rather as ExpressionStatement.
+
+	* attribute.cs: Treat indexers and properties as the same in terms
+	of applying attributes
+
+	* ecore.cs (FindMostEncompassedType): Use statically initialized
+	EmptyExpressions()s like we do elsewhere to avoid creating useless
+	objects (and we take this out of the tight loop).
+
+	(GetConversionOperators): Move the code to extract the actual
+	operators to a separate routine to clean things up.
+
+2002-05-04  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (FieldExpr): Remove un-needed tests for null, since now
+	events are always registered FieldBuilders.
+	
+	* class.cs (FieldBase): New class shared by Fields 
+
+	* delegate.cs: If we are a toplevel delegate, use our full name.
+	If we are a nested delegate, then only use our tail name.
+
+2002-05-02  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (IsApplicable): Ensure that we add the "&" to
+	ref/out types before comparing it with the type of the argument.
+
+	(IsParamsMethodApplicable): Ditto.
+
+	(Argument.Type): Use TypeManager.LookupType instead of Type.GetType - 
+	silly me ;-)
+
+	* delegate.cs : Handle the case when we have more than one applicable
+	method. Flag an error only when we finish checking all.
+
+2002-05-02  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs: Add support for boolean static initializers.
+
+2002-05-01  Miguel de Icaza  <miguel@ximian.com>
+
+	* attribute.cs: Use proper cast for Events, since we use a MyEventBuilder.
+
+	* parameter.cs (ComputeParameterTypes,
+	ComputeAndDefineParameterTypes): Better error handling: now we
+	clear the `types' cache if we fail during any of the type lookups.
+	We also return the status code correctly to our caller
+
+	* delegate.cs: If we fail to define a delegate, abort the extra
+	steps. 
+
+	* expression.cs (Binary.ResolveOperator): for
+	operator==(object,object) and operator !=(object, object) we also
+	have to verify that there is an implicit conversion from one to
+	the other.
+
+	(ArrayAccess.DoResolve): Array Access can operate on
+	non-variables. 
+
+2002-04-30  Miguel de Icaza  <miguel@ximian.com>
+
+	* assign.cs (CompoundAssign): A new class used as a "flag" that
+	the assignment actually is happening as part of a compound
+	assignment operator.
+
+	During compound assignment, a few new rules exist to enable things
+	like:
+
+	byte b |= 1 + 2
+
+	From the spec:
+	
+	x op= y can be evaluated as x = (T) (x op y) (ie, an explicit cast
+	to the type of x) if y is implicitly convertible to the type of x,
+	and the operator is a builtin operator and the return type of the
+	operator is explicitly convertible to the type of x. 
+
+	* rootcontext.cs: Reset warning level to 2.  4 catches various
+	"interesting" features in mcs, we must clean this up at some
+	point, but currently am trying to kill other bugs ;-)
+
+	* ecore.cs (SimpleName.SimpleNameResolve): Perform member lookups
+	in container classes as well.  
+
+	* expression.cs (Binary.ResolveOperator): Handle string case
+	before anything else (as operator overloading does emit an error
+	before doing anything else).
+
+	This code could go away when we move to a table driven model, but
+	i could not come up with a good plan last night.
+	
+2002-04-30  Lawrence Pit <loz@cable.a2000.nl>
+
+	* typemanager.cs (CSharpName): reimplementation using regex.
+	* class.cs: added null check for fields in Emit
+	* rootcontext.cs: set warninglevel to 4
+
+2002-04-29  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs (CSharpName): reimplemented with Lupus
+	suggestion.
+
+2002-04-28  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (If): correclty implement Resolve, because we were
+	not catching sem errors in there.  The same process is needed
+	everywhere else. 
+	(Return, StatementExpression, For, While, Do, Throw, Lock): Implement Resolve
+	
+
+	(Statement.Warning_DeadCodeFound): Factorize code.
+	(While): Report dead code here too.
+
+	(Statement): Added Resolve virtual method to allow
+	for resolution split from the emit code.
+
+2002-04-26  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (EmitBoolExpression): No longer try to resolve the
+	expression here.    
+	(MakeBoolean): New utility function that resolve, implicitly
+	converts to boolean and tags the expression. 
+	
+
+	(If, Do): Implement dead code elimination.
+	(While): Implement loop inversion
+
+	(Do, While, For, If): Resolve the expression prior to calling our
+	code generation.
+
+2002-04-22  Lawrence Pit <loz@cable.a2000.nl>
+
+	* class.cs:
+	  - added method Report28 (warning: program has more than one entry point)
+	  - added method IsEntryPoint, implements paragraph 10.1 of the spec
+	  - modified method Method.Define, the part at the end of the method
+
+	* rootcontext.cs: added static public Location EntryPointLocation;
+	  
+	* ../errors/cs0028.cs : Add test case for the above warning.		  
+
+	* typemanager.cs:
+	  - modified method CSharpName to allow arrays of primitive type to
+	    be printed nicely (e.g. instead of System.Int32[][] it now prints
+	    int[][])
+	  - added method CSharpSignature: returns the signature of a method
+	    in string format to be used in reporting errors, warnings, etc.
+
+	* support.cs: InternalParameters.ParameterDesc variable tmp initialized
+	with String.Empty.
+	
+2002-04-26  Ravi Pratap  <ravi@ximian.com>
+
+	* delegate.cs (Define): Fix extremely silly bug where I was
+	setting the type of the 'object' parameter of the BeginInvoke
+	method to System.IAsyncResult instead of System.Object ;-)
+
+2002-04-26  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (ConstructorInitializer.Resolve): Also use DeclaredOnly
+	here. 
+
+	(Constructor.Emit): return if we fail to initialize the
+	constructor.  Another door closed!  
+
+	* expression.cs (New.DoResolve): Improve error message (from -6 to
+	1501).  Use DeclaredOnly lookup to find the exact constructor.
+
+	* typemanager.cs (MemberLookup): If DeclaredOnly is set, do not
+	loop.  This is useful.
+
+	* cs-parser.jay: Adjust the default parameters so that destructors
+	have the proper signature.
+
+2002-04-26  Martin Baulig  <martin@gnome.org>
+
+	* driver.cs (LoadAssembly): If `assembly' contains any characters
+	which are only valid in path names and not in assembly names
+	(currently slash, backslash and point), use Assembly.LoadFrom ()
+	instead of Assembly.Load () on the `assembly' (before iteration
+	over the link_paths).
+
+2002-04-26  Martin Baulig  <martin@gnome.org>
+
+	* cs-tokenizer.cs (is_hex): Correctly handle lowercase chars.
+
+2002-04-25  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Property): use the new typemanager.MemberLookup
+
+	(TypeContainer.MemberLookup): Implement using the
+	TypeManager.MemberLookup now. 
+	
+	* typemanager.cs: Make MemberLookup a function of the TypeManager,
+	and return MemberInfos, so that these can be used without an
+	EmitContext (what we had before).
+
+2002-04-24  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs: Fix the case where the argument to params if the
+	type of the params.  I omitted handling this before.   Fixed
+
+2002-04-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs: Call BootCorlib_PopulateCoreType
+
+	* class.cs (Property.CheckBase): Check for properties only, not
+	for all members. 
+
+	* interface.cs: Temporary hack: try/catch around the
+	CustomAttributeBuilder, because I am getting an exception that I
+	do not understand.
+
+	* rootcontext.cs (BootCorlib_PopulateCoreType): Populate some
+	types whose definitions are required to be there (attributes are
+	defined before standard types).
+
+	Compute definitions as we boot the various types, as they are used
+	immediately (value_type class will need object_type, but if we do
+	not initialize object_type, we will pass a null, which will let
+	the runtime pick the System.Object from the existing corlib, which
+	is not what we want).
+
+2002-04-22  Patrik Torstensson <totte@labs2.com>
+
+	* cs-tokenizer.cs: fixed a number of trim() issues.
+
+2002-04-22  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (Argument.Type): Ensure that we return the correct
+	type when we have out or ref parameters [in which case we 
+	append a "&"].
+	
+2002-04-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Property, Indexer): Allow extern modifier in there. 
+
+	* typemanager.cs (InitBaseTypes): Initializes object_type and
+	value_type, since those will be used early on during the bootstrap
+	process to compile corlib.
+
+	(InitCoreTypes): Move code from here to InitBaseTypes.
+
+2002-04-21  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (PropertyExpr): Optimize calls to Array::get_Length on
+	single-dimension arrays as using the ldlen opcode.  
+
+	Daniel Lewis discovered this optimization.  
+
+	* typemanager.cs: Add signature for System.Array::get_Length
+
+2002-04-20  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* statement.cs: report the error when the foreach does not apply to an
+	array nor a collection.
+
+2002-04-19  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs: Add implicit conversions to the operator ~.
+
+	* constant.cs (DecimalConstant.Emit): Emit decimal value.
+
+	* typemanager.cs: Locate the decimal constructor.
+
+2002-04-17  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* attribute.cs: use the new property of TypeOf.
+	* expression.cs: added 'get' property around typearg.
+
+	These changes fix a build breaker reported by NickD. Is this the
+	correct way to fix?  If not, please, revert my changes and make it
+	work :-).
+
+2002-04-17  Miguel de Icaza  <miguel@ximian.com>
+
+	* attribute.cs: Add support for typeof in attribute invocations.
+	I am not sure that this is right though.
+
+2002-04-14  Duncan Mak  <duncan@ximian.com>
+
+	* cfold.cs (BinaryFold): Catch DivideByZeroException in the
+	Binary.Operator.Division case.
+
+2002-04-13  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (DefineType): Ensure that we do a proper check on
+	attribute types and also register it with the TypeManager.
+
+	(TypeContainer.Targets): The default for attribute types is
+	AttributeTargets.All.
+	
+	* attribute.cs (ApplyAttributes): Registering the attribute type
+	is done elsewhere, not when we discover we have a Usage attribute.
+
+2002-04-12  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (VerifyArgumentsCompat): Implement Miguel's suggestion
+	and get rid of is_delegate parameter.
+
+	* everywhere : update.
+	
+2002-04-12  Ravi Pratap  <ravi@ximian.com>
+
+	* cs-parser.jay (compilation_unit): Revamp completely to use
+	some new ideas that I got from Rhys' grammar to solve the problems
+	with assembly level attributes.
+
+	(outer_declaration): New grammar production.
+
+	(attribute_sections): Add.
+
+	(opt_attributes): Base on attribute_sections
+
+	(namespace_declaration): Allow opt_attributes to tackle the case
+	when we have assembly level attributes - we are clever in this
+	regard now ;-)
+
+	* attribute.cs (ApplyAttributes): Do not worry about assembly 
+	attributes in the non-global context.
+
+	* rootcontext.cs (AddGlobalAttributes): Go back to using this
+	instead of SetGlobalAttributes.
+
+	* class.cs, rootcontext.cs : Ensure we define and generate 
+	attribute types before anything else.
+
+	* attribute.cs (CheckAttribute and GetValidPlaces): Handle the exception
+	and flag the new error -20 for the case when the attribute type
+	does not have valid targets specified. csc does not catch this.
+
+	* ../errors/errors.txt : update for error # -20
+
+2002-04-11  Ravi Pratap  <ravi@ximian.com>
+
+	* support.cs (InternalParameters.ParameterModifier): Do some null
+	checking and return sane values.
+
+	* class.cs (Method.Define): If we are a PInvoke method, ensure
+	that we are static and extern. Report error # 601
+
+	* ../errors/cs0601.cs : Add test case for the above error.
+
+2002-04-07  Ravi Pratap  <ravi@ximian.com>
+
+	* rootcontext.cs (attribute_types): We need to keep type of
+	all attribute types separately and emit code for them first.
+
+	(RegisterAttribute) : Implement.
+
+	* class.cs (DefineType): Check if the current Type is a custom
+	attribute type and register it accordingly.
+
+	* rootcontext.cs (AddGlobalAttributes): Fix silly bug where we were
+	adding the first attribute twice and rename to
+
+	(SetGlobalAttributes): this.
+
+	* rootcontext.cs (NamespaceLookup): Run through the aliases too and perform
+	lookups.
+
+	* attribute.cs (ApplyAttributes): Take an additional argument telling us
+	if we are processing global arguments. Hmm, I am unsure of this.
+
+2002-04-12  Gonzalo Paniagua Javier <gonzalo@ximian.com>
+
+	* expression.cs: added static array of strings to avoid calling
+	Enum.ToString () for Operator in Binary. Significant recover of
+	performance.
+
+2002-04-10  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (FindMembers): Allow the Builders of the various
+	members to be null.  If they are skip them.  This only happens
+	during the PInvoke declaration.
+
+2002-04-09  Miguel de Icaza  <miguel@ximian.com>
+
+	* parameter.cs (Parameters.ComputeParameterTypes): Flag the
+	failure, so we do not keep going afterwards.
+
+	* expression.cs: (Invocation.OverloadResolve): I believe Ravi
+	wanted to pass `false' as the `is_delegate' argument.  If this is
+	the case, why not use delegate_type == null to mean `is_delegate =
+	false' and anything else as is_delegate = true.
+
+Tue Apr  9 05:40:12  2002 Piers Haken <piersh@friskit.com>
+
+	* statement.cs: fixed SimpleSwitchEmit to make 'goto case' goto the
+	code for the section, not the beginning of the tests.
+
+2002-04-08  Miguel de Icaza  <miguel@ximian.com>
+
+	* cfold.cs: Handle operator + (Enum x, Underlying x) 
+
+	* expression.cs (Binary): same.  Warn about errors where we have
+	Enum/Enum in operator + as well.
+
+Mon Apr  8 06:29:03  2002 Piers Haken <piersh@friskit.com>
+
+	* statement.cs:
+		- added support for switch(bool)
+		- optimize loading of I8/U8 constants (ldc.i4, iconv_i8)
+		- add TableSwitchEmit() to handle table-based switch statements
+
+2002-04-05  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (Invocation.OverloadResolve): Factor out code which
+	does parameter compatibility checking with arguments so that we can 
+	re-use the code even from Delegate.VerifyApplicability
+
+	(VerifyArgumentsCompat): Move above code here.
+
+	* delegate.cs (VerifyApplicability): Get rid of duplicate code
+	and instead make a call to the above method.
+
+2002-03-31  Ravi Pratap  <ravi@ximian.com>
+
+	* typemanager.cs (attribute_type): Corresponds to System.Attribute.
+	We use it to keep track of classes which are attribute types.
+
+2002-04-02  Miguel de Icaza  <miguel@ximian.com>
+
+	* delegate.cs (Delegate.Define): Correctly define the types in the
+	presence of fixed and array parameters.
+
+	* class.cs (TypeContainers.FindMembers): Use NonPublic flag while
+	doing FindMembers.
+
+	* ecore.cs (Expression.MemberLookup): Reset binding flags to not
+	include NonPublic after the first iteration.
+
+	* class.cs (Indexer.CheckBase): Only check if both parents are
+	non-null. 
+	
+	* cs-parser.jay (accessor_body): If empty, set to null.
+
+	* ecore.cs (SimpleName.SimpleNameResolve): We did not have the
+	same code path here to resolve constants names that we did have in
+	MemberAccess.DoResolve.  There is too much code duplicated here.
+
+2002-04-01  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs, makefile: Drop Statementcollection and just use ArrayLists
+
+	* ecore.cs: Optimize UserDefinedConversion by minimizing the calls
+	to MakeUnionSet.
+
+	* cs-tokenizer.cs: Reuse a single StringBuilder for assembling
+	tokens, numbers and strings.
+
+	* ecore.cs (MethodGroupExpr): Make Emit warn about missing
+	parenthesis.
+
+	* delegate.cs: Use ComputeAndDefineParameterTypes for both the
+	asyncronous parameters and the regular parameters.  
+
+	* codegen.cs (CodeGen.Init): Use the constructor that allows us to
+	specify the target directory.
+
+	* expression.cs: (This.DoResolve): Simplify
+	(As.Emit): Optimize, do not generate IsInst if the expression is
+	always of the given type.
+
+	(Is.DoResolve): Bug fix, we were reporting both always/never for
+	the is expression.
+
+	* (Invocation.MakeUnionSet): Simplify vastly and optimize, we were
+	creating too many unnecessary arrays.
+
+2002-03-31  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (EmitFieldInitializer): Use Assign expression to assign
+	fields instead of rolling our own initializer.   Takes care of all
+	implicit conversions, and drops unnecessary static checks/argument.
+
+2002-03-31  Dick Porter  <dick@ximian.com>
+
+	* driver.cs: use the GetDirectories() return values properly, and
+	use "/" as path separator.
+
+2002-03-30  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (Unary): Optimize - - expr into expr.
+	(Binary): Optimize a + (-b) into a -b.
+
+	* codegen.cs (CodeGen): Made all methods static.
+
+2002-03-29  Miguel de Icaza  <miguel@ximian.com>
+
+	* rootcontext.cs: 
+
+	* decl.cs: Rename `definition' into `TypeBuilder' and drop the
+	TypeBuilder property.
+
+	* cs-parser.jay: Drop the use of RecordXXX and use RecordDecl
+	instead. 
+
+	* tree.cs: Removed the various RecordXXXX, and replaced with a
+	single RecordDecl.  Removed all the accessor methods, and just
+	left a single access point Type 
+
+	* enum.cs: Rename DefineEnum to DefineType.
+
+	* decl.cs: New abstract method `DefineType' used to unify the
+	Defines for Enumerations, Interfaces, TypeContainers and
+	Delegates.
+
+	(FindType): Moved LookupInterfaceOrClass here.  Moved the
+	LookupBaseClasses method that used to live in class.cs and
+	interface.cs here, and renamed to FindType.
+	
+	* delegate.cs: Implement DefineType.  Take advantage of the
+	refactored pattern for locating the parent builder without taking
+	the parent_builder argument (which we know does not work if we are
+	nested, and triggering a toplevel definition).
+
+2002-03-28  Miguel de Icaza  <miguel@ximian.com>
+
+	* decl.cs (MemberCore.CheckMethodAgainstBase): Test if the
+	accessibility of a member has changed during override and report
+	an error if so.
+
+	* class.cs (Method.Define, Property.Define): Only complain on
+	overrides if the method is private, any other accessibility is
+	fine (and since we just checked the permission is the same, we are
+	good to go).
+
+	* cs-tokenizer.cs: only line, region, endregion, if, endif, else
+	and elif are processed always.  The other pre-processing
+	directives are only processed if we are "taking" the path
+
+2002-03-29  Martin Baulig  <martin@gnome.org>
+
+	* class.cs (Method.Emit): Only emit symbolic debugging info if the
+	current location is not Null.
+
+	* codegen.cs (CodeGen.SaveSymbols): Split out symbol writing code into
+	a separate method so we can profile it.
+
+	* driver.cs (ShowTime): We need to use `(int) span.TotalSeconds' since
+	`span.Seconds' are just seconds, but no minutes or hours.
+	(MainDriver): Profile the CodeGen.SaveSymbols calls.
+
+2002-03-28  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Method.Define), (Property.Define), (Indexer.Define):
+	Remove the gratuitous set of Final:
+
+				// If an interface implementation, then we can set Final.
+				if (((flags & MethodAttributes.Abstract) == 0) &&
+				    implementing.DeclaringType.IsInterface)
+					flags |= MethodAttributes.Final;
+
+        I do not know what I was smoking when I used that.
+	
+
+	* cs-parser.jay, delegate.cs: Make Delegate be a DeclSpace, first
+	step into fixing the name resolution issues for delegates and
+	unifying the toplevel name resolution.
+
+2002-03-28  Martin Baulig  <martin@gnome.org>
+
+	* class.cs (Method.Emit): If we have a symbol writer, call its
+	OpenMethod(), CloseMethod() and SetMethodSourceRange() methods to
+	tell it about the current method.
+
+	* codegen.cs (EmitContext.Mark): New public method. Tell the symbol
+	writer that we're going to emit the first byte of IL code for a new
+	statement (a new source line).
+	(EmitContext.EmitTopBlock): If we have a symbol writer, call
+	EmitContext.Mark() before emitting any code.
+
+	* location.cs (SymbolDocument): Return null when we're Null.
+
+	* statement.cs (Statement): Moved the `Location loc' variable here.
+	(Statement.EmitBoolExpression): If we have a symbol writer, call
+	ec.Mark() before emitting any code to tell it that we're at the
+	beginning of a new statement.
+	(StatementExpression): Added `Location' argument to the constructor.
+	(Block): Added public readonly variable `StartLocation' and public
+	variable `EndLocation'.  The latter is to be set using SetEndLocation().
+	(Block): Added constructor which takes a start and end location.
+	(Block.SetEndLocation): New method. This sets the end location.
+	(Block.EmitMeta): If we have a symbol writer, tell it the names of the
+	local variables we create.
+	(Block.Emit): If we have a symbol writer, call ec.Mark() before emitting
+	each statement and do also mark the begin and end of the block.
+
+	* cs-parser.jay (block : OPEN_BRACE): Use the new `Block' constructor to
+	tell it the current lexer.Location, use Location.Null for the end of the
+	block.
+	(block : OPEN_BRACE opt_statement_list CLOSE_BRACE): When closing the
+	current block, set its end location using SetEndLocation().
+	(statement_expression): StatementExpression constructor now takes the
+	lexer.Location as additional argument.
+	(for_statement, declare_local_variables): Likewise.
+	(declare_local_variables): When creating a new implicit block, use the
+	new Block constructor and pass it the lexer.Location.
+
+2002-03-28  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (Expression.MemberLookup): On interfaces, lookup
+	members also on the parent interfaces recursively.
+
+2002-03-27  Miguel de Icaza  <miguel@ximian.com>
+
+	* report.cs: Use new formats, since Gonzalo finished the missing
+	bits. 
+
+	* expression.cs (Binary.ResolveOperator): added missing operator|
+	operator& and operator^ for bool/bool.
+
+	* cs-parser.jay: CheckDef now takes a Location argument that is
+	used to report errors more precisly (instead of reporting the end
+	of a definition, we try to track something which is a lot closer
+	to the source of the problem).
+
+	* cs-tokenizer.cs: Track global token use, so we can properly flag
+	the use of #define/#undef after the first token has been seen.
+
+	Also, rename the reportXXXX to Error_DescriptiveName
+
+	* decl.cs (DeclSpace.IsTopLevel): Move property here from
+	TypeContainer, so that Enum and Interface can use this too.
+
+	* class.cs (TypeContainer.LookupInterfaceOrClass,
+	GetInterfaceOrClass, GetClassBases, DefineType): Drop the
+	`builder' argument.  Typically this was used to pass the parent
+	builder (a ModuleBuilder or a TypeBuilder from whoever triggered
+	the definition).  
+
+	The problem is that a nested class could trigger the definition of
+	a toplevel class, and the builder would be obviously wrong in that
+	case. 
+
+	So we drop this argument, and we compute dynamically the
+	TypeBuilder/ModuleBuilder (the correct information was available
+	to us anyways from DeclSpace.Parent)
+
+	* interface.cs (Interface.DefineInterface): Drop builder
+	parameter cleanup like class.cs
+
+	* enum.cs (Enum.DefineEnum): Drop builder parameter.  Clean up
+	like class.cs
+
+	* statement.cs (Switch.EmitObjectInteger): Emit short/ushort
+	values. 
+
+	(Try.Emit): Propagate the returns value from the statement.
+
+	(Return.Emit): Even if we are leavning 
+
+	* driver.cs: Catch IOExpcetion for Directory.GetFiles as well.
+
+	* modifiers.cs: Fix the computation of MethodAttributes flags.
+
+Tue Mar 26 21:14:36 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* driver.cs: allow compilation of files that start with '/'.
+	Add a default case when checking the argument of --target.
+
+2002-03-25  Miguel de Icaza  <miguel@ximian.com>
+
+	* interface.cs: Implement the same search algorithm for types in
+	the interface code.
+
+	* delegate.cs: Do not allow multiple definition.
+
+	* Recovered ChangeLog that got accidentally amputated
+
+	* interface.cs (Interface.DefineInterface): Prevent from double definitions.
+
+	* rootcontext.cs: Load manually enum to allow core classes to
+	contain enumerations.
+
+	* enum.cs, ecore.cs, driver.cs, attribute.cs, class.cs, expression.cs:
+	Update to new static methods in TypeManager.
+
+	* typemanager.cs (GetMethod, GetConstructor): Use our
+	implementation of FindMembers to find the members, since during
+	corlib compilation, the types are TypeBuilders and GetMethod and
+	GetConstructor do not work.
+
+	Make all methods in TypeManager static.
+
+	(InitCodeHelpers): Split the functionality from
+	the InitCodeTypes function.
+
+	* driver.cs: Call InitCodeHelpers after we have populated the
+	types. 
+
+	* cs-parser.jay (delegate_declaration): we did not used to compute
+	the delegate name correctly for void delegates.
+
+2002-03-24  Miguel de Icaza  <miguel@ximian.com>
+
+	* rootcontext.cs (RootContext): Init the interface_resolve_order
+	and type_container_resolve_order always.
+
+	(ResolveCore, BootstrapCorlib_ResolveClass,
+	BootstrapCorlib_ResolveStruct): New functions to bootstrap the
+	compiler when compiling with --nostdlib
+
+	* class.cs (TypeContainer.DefineType): Check that our parent is
+	not null.  This test is most important when we are bootstraping
+	the core types.
+
+	* codegen.cs: Split out the symbol writing code.
+
+2002-03-25  Martin Baulig  <martin@gnome.org>
+
+	* driver.cs (-g): Made -g an alias for --debug.
+
+2002-03-24  Martin Baulig  <martin@gnome.org>
+
+	* codegen.cs (SymbolWriter): New public variable. Returns the
+	current symbol writer.
+	(CodeGen): Added `bool want_debugging_support' argument to the
+	 constructor. If true, tell the ModuleBuild that we want debugging
+	support and ask it for the ISymbolWriter.
+	(Save): If we have a symbol writer, call it's Close() method after
+	saving the assembly.
+
+	* driver.c (--debug): New command line argument to create a
+	debugger information file.
+
+	* location.cs (SymbolDocument): New public property. Returns an
+	ISymbolDocumentWriter object for the current source file or null
+	if we don't have a symbol writer.
+
+2002-03-21  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs (LoadAssembly): Correctly return when all the paths
+	have been tried and not before.
+
+	* statement.cs (Switch.Emit): return the actual coverage for this
+	statement (returns/not-returns)
+
+	(Switch.SimpleSwitchEmit): Do not generate jumps to the end of the
+	switch of the statement if we are the last switch section.  That
+	kills two problems: try/catch problems (we used to emit an empty
+	nop at the end) and switch statements where all branches would
+	return. 
+
+2002-03-19  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs: Add default assemblies (the equivalent to the
+	Microsoft CSC.RSP file)
+
+	* cs-tokenizer.cs: When updating `cols and setting it to zero,
+	also update tokens_seen and set it to false.
+
+	* driver.cs: Implement --recurse for Mike.
+
+	* driver.cs (SplitPathAndPattern): Small bug fix, I was not
+	correctly splitting out the paths.
+
+2002-03-18  Miguel de Icaza  <miguel@ximian.com>
+
+	* interface.cs (Interface.PopulateProperty): Instead of using
+	`parent' as the declaration space for the set parameters, use
+	`this' 
+
+	* support.cs (InternalParameters): InternalParameters constructor
+	takes a DeclSpace instead of a TypeContainer.
+
+	* expression.cs (ArrayCreation.EmitDynamicInitializers): If value
+	types are being initialized, load the address of it before calling
+	the function.  
+
+	(New): Provide a mechanism to disable the generation of local
+	value type temporaries when the caller will be providing us with
+	an address to store it.
+
+	(ArrayCreation.EmitDynamicInitializers): Use it.
+
+2002-03-17  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (Invocation.EmitArguments): Only probe for array
+	property if there is more than one argument.  Sorry about that.
+
+	* class.cs (Invocation.EmitArguments): Fix to emit arguments for
+	empty param arrays.
+	
+	* class.cs (Method.LabelParameters): Fix incorrect code path that
+	prevented the `ParamArrayAttribute' from being applied to the
+	params attribute.
+
+2002-03-16  Miguel de Icaza  <miguel@ximian.com>
+
+	* support.cs (ReflectionParameters): Correctly compute whether the
+	last argument is a params array.  Fixes the problem with
+	string.Split ('a')
+
+	* typemanager.cs: Make the assemblies array always be non-null
+	(empty, but non-null)
+
+	* tree.cs (RecordDecl): New function that abstracts the recording
+	of names.  This reports error 101, and provides a pointer to the
+	previous declaration.  Fixes a crash in the compiler.
+
+	* cs-parser.jay (constructor_declaration): Update to new grammar,
+	and provide a constructor_body that can be empty.
+
+2002-03-15  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs: Add support for --resources.
+
+	* expression.cs: (FetchGetMethod, FetchAddressMethod, EmitAssign):
+	Make all types for the various array helper methods be integer.
+
+	* ecore.cs (Expression.ConvertNumericExplicit): Pass the
+	CheckState to ConvCast.
+
+	(ConvCast): Now it takes a `checked' state argument, to avoid
+	depending on the emit context for the conversion, and just using
+	the resolve time setting.
+
+	* expression.cs (ArrayCreation.EmitArrayArguments): New function,
+	instead of Invocation.EmitArguments.  We do not emit the original
+	arguments, instead we emit those which have been converted to
+	unsigned int expressions.
+
+	* statement.cs (Block.EmitMeta): Drop tracking of indexes.
+
+	* codegen.cs: ditto.
+
+	* expression.cs (LocalVariableReference): Drop the use of the
+	Store function that depended on the variable index.
+
+	* statement.cs (VariableInfo): Drop the `Idx' property from this
+	class, as this is not taking into account the indexes for
+	temporaries tat we generate during the execution, getting the
+	indexes wrong.
+
+	* class.cs: First emit class initializers, then call the parent
+	constructor. 
+
+	* expression.cs (Binary): Fix opcode emision.
+	(UnaryMutator.EmitCode): Support checked code generation
+
+	* ecore.cs (MemberLookup): TypeManager.FindMembers will return
+	matches for events for both the Static and Instance scans,
+	pointing to the same element.   Fix that.
+
+2002-03-14  Miguel de Icaza  <miguel@ximian.com>
+
+	* rootcontext.cs (ResolveTree): Always set the
+	interface_resolve_order, because nested interfaces will be calling
+	into us.
+
+	* class.cs (GetInterfaceOrClass): Track the same resolution
+	process used by TypeManager.LookupType.  This fixes the nested
+	type lookups in class declarations (separate path from
+	LookupType). 
+
+	(TypeContainer.DefineType): Also define nested interfaces.
+	(TypeContainer.RegisterOrder): New public function used to
+	register the order in which child interfaces need to be closed.
+
+	Nested interfaces need to be closed after their parents have been
+	created. 
+	
+	* interface.cs (InterfaceAttr): Put all the logic for computing
+	the interface attribute here. 
+
+	(DefineInterface): Register our interface order with the
+	RootContext or with the TypeContainer depending on the case.
+
+2002-03-12  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay: rework foreach statement to work with the new
+	changes to the policy on SimpleNames.
+	
+	* report.cs: support Stacktrace on warnings as well.
+
+	* makefile: drop --unsafe and /unsafe from the compile.
+
+2002-03-13  Ravi Pratap  <ravi@ximian.com>
+
+	* ecore.cs (StandardConversionExists): Modify to take an Expression
+	as the first parameter. Ensure we do null -> reference type conversion
+	checking.
+
+	* Everywhere : update calls accordingly, making use of MyEmptyExpr to store
+	temporary Expression objects.
+
+Wed Mar 13 12:32:40 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* interface.cs: workaround bug in method overloading resolution
+	(there is already a bugzilla bug for it).
+
+2002-03-12  Miguel de Icaza  <miguel@ximian.com>
+
+	We could also solve this problem by having a separate path for
+	performing type lookups, instead of DoResolve, we could have a
+	ResolveType entry point, and only participating pieces of the
+	production (simplename, deref, array) would implement this. 
+	
+	* codegen.cs (EmitContext): New field OnlyLookupTypes used to
+	signal SimpleName to only resolve type names and not attempt to
+	resolve anything else.
+
+	* expression.cs (Cast): Set the flag.
+
+	* ecore.cs (SimpleName): Use the OnlyLookupTypes flag
+
+	* class.cs: Only report 108 if there is no `new' modifier.
+
+	* cs-parser.jay: rework foreach statement to work with the new
+	changes to the policy on SimpleNames.
+	
+	* report.cs: support Stacktrace on warnings as well.
+
+	* makefile: drop --unsafe and /unsafe from the compile.
+
+2002-03-11  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
+	lookups here, instead of doing that at parse time.  This means
+	that our grammar will not introduce `LocalVariableReferences' as
+	expressions at this point.  That solves the problem of code like
+	this:
+
+	class X {
+	   static void Main ()
+	   { int X = 1;
+	    { X x = null }}}
+
+	This is only half the fix.  The full fix requires parameters to
+	also be handled in this way.
+
+	* Everywhere: Use ec.DeclSpace on calls to LookupType, as this
+	makes the use more obvious of the DeclSpace.  The
+	ec.TypeContainer.TypeBuilder is now only used to pull the
+	TypeBuilder for it.
+
+	My theory is that I can get rid of the TypeBuilder completely from
+	the EmitContext, and have typecasts where it is used (from
+	DeclSpace to where it matters).  
+
+	The only pending problem is that the code that implements Aliases
+	is on TypeContainer, and probably should go in DeclSpace.
+
+	* ecore.cs (SimpleName.SimpleNameResolve): Perform local variable
+	lookups here, instead of doing that at parse time.  This means
+	that our grammar will not introduce `LocalVariableReferences' as
+	expressions at this point.  That solves the problem of code like
+	this:
+
+	class X {
+	   static void Main ()
+	   { int X = 1;
+	    { X x = null }}}
+
+	This is only half the fix.  The full fix requires parameters to
+	also be handled in this way.
+
+	* class.cs (Property.DefineMethod): When implementing an interface
+	method, set newslot, when implementing an abstract method, do not
+	set the flag (before we tried never setting it, or always setting
+	it, which is the difference).
+	(Indexer.DefineMethod): same.
+	(Method.DefineMethod): same.
+
+	* ecore.cs: Only set the status used flag if we get back a Field.
+
+	* attribute.cs: Temporary hack, so Paolo can keep working.
+
+2002-03-08  Ravi Pratap  <ravi@ximian.com>
+
+	* attribute.cs (Attribute.UnmanagedType): This is to keep track of
+	the unmanaged type in the case we have a MarshalAs attribute.
+
+	(Resolve): Handle the case when we are parsing the special MarshalAs
+	attribute [we need to store the unmanaged type to use later]
+	
+	* typemanager.cs (marshal_as_attr_type): Built in type for the 
+	MarshalAs Attribute.
+
+	* attribute.cs (ApplyAttributes): Recognize the MarshalAs attribute 
+	on parameters and accordingly set the marshalling info.
+	
+2002-03-09  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs: Optimizing slightly by removing redundant code after
+	we switched to the `NoTypes' return value.
+	(Property.DefineMethod): use NoTypes here too.
+
+	This fixes the bug I introduced in my last batch of changes.
+
+2002-03-05  Ravi Pratap  <ravi@ximian.com>
+
+	* tree.cs (RecordEnum): Add. We now keep track of enums too.
+
+	* class.cs (LookupInterfaceOrClass): Check against the list of recorded
+	Enums since those are types too. 
+
+	* cs-parser.jay (enum_declaration): Record enums as we parse them.
+	
+	* enum.cs (DefineEnum): Return if the TypeBuilder has already been defined 
+	thanks to a call during the lookup process.
+
+2002-03-07  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (Foreach): Lots of work to accomodate a particular
+	kind of foreach statement that I had not kept in mind.  It is
+	possible to have foreachs on classes that provide a GetEnumerator
+	method that return objects that implement the "pattern" for using
+	a foreach, there is no need to support GetEnumerator
+	specifically. 
+
+	This is needed to compile nant.
+
+	* decl.cs: Only report 114 if the member is not `Finalize' and if
+	the warning level is at least 2.
+
+	* class.cs: Moved the compare function from Method to
+	MethodSignature. 
+
+	(MethodSignature.InheritableMemberSignatureCompare): Add new
+	filter function that is used to extract inheritable methods from a
+	class. 
+
+	(Method.Define): Use the new `inheritable_method_signature_filter'
+	delegate
+
+	* cs-tokenizer.cs (get_cmd_arg): Do not add white space to the
+	command. 
+
+2002-03-06  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (Expression.ConvertReferenceExplicit): Removed dead code.
+
+	* cs-parser.jay: Add opt_semicolon to the interface declaration.
+
+	* expression.cs: Pass location information to
+	ConvertImplicitStandard. 
+
+	* class.cs: Added debugging code to track return values from
+	interfaces. 
+
+2002-03-05  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (Is.DoResolve): If either side of the `is' is an
+	interface, do not flag the warning.
+
+	* ecore.cs (ImplicitReferenceConversion): We need a separate test
+	for interfaces
+
+	* report.cs: Allow for --fatal to be used with --probe.
+	
+	* typemanager.cs (NoTypes): Move the definition for the empty Type
+	array here. 
+
+	* class.cs (TypeContainer.FindMembers): Also look for methods defined by
+	properties. 
+	(TypeContainer.DefineProxy): New function used to proxy to parent
+	implementations when implementing interfaces.
+	(TypeContainer.ParentImplements): used to lookup if our parent
+	implements a public function that is required by an interface.
+	(TypeContainer.VerifyPendingMethods): Hook this up.
+
+	* typemanager.cs (TypeManager, AddModule, AddAssembly): Make the
+	`modules' and `assemblies' arraylists into arrays.  We only grow
+	these are the very early start up of the program, so this improves
+	the speedof LookupType (nicely measured).
+
+	* expression.cs (MakeByteBlob): Replaced unsafe code with
+	BitConverter, as suggested by Paolo.
+
+	* cfold.cs (ConstantFold.Binary): Special case: perform constant
+	folding of string concatenation, but if either side is a string,
+	and the other is not, then return null, and let the runtime use
+	the concatenation on the string plus the object (using
+	`Object.ToString'). 
+
+2002-03-04  Miguel de Icaza  <miguel@ximian.com>
+
+	Constant Folding has been implemented now.
+	
+	* expression.cs (Unary.Reduce): Do not throw an exception, catch
+	the error instead on types that are not supported in one's
+	complement. 
+
+	* constant.cs (Constant and all children): New set of functions to
+	perform implict and explicit conversions.
+	
+	* ecore.cs (EnumConstant): Implement the new functions to perform
+	conversion by proxying to the child expression.
+
+	* codegen.cs: (ConstantCheckState): Constant evaluation has its
+	own separate setting that can not be turned off from the command
+	line using --unchecked or --checked and is only controlled using
+	the checked/unchecked statements and expressions.  This setting is
+	used by the constant folder to flag errors.
+
+	* expression.cs (CheckedExpr, UncheckedExpr): Set the
+	ConstantCheckState as well.   
+
+	During Resolve, they also have to flag the state, because the
+	constant folder runs completely in the Resolve phase.
+
+	* statement.cs (Checked, Unchecked): Set the ConstantCheckState as
+	well.
+
+2002-03-01  Miguel de Icaza  <miguel@ximian.com>
+
+	* cfold.cs: New file, this file contains the constant folder.
+	
+	* ecore.cs (IMemoryLocation.AddressOf): Now takes an extra
+	argument to track whether we are using the resulting address to
+	load or store a value and provide better error messages. 
+
+	(FieldExpr.Emit, FieldExpr.EmitAssign, FieldExpr.AddressOf): Use
+	new AddressOf arguments.
+
+	* statement.cs (Foreach.EmitCollectionForeach): Update
+
+	* expression.cs (Argument.Emit): Call AddressOf with proper
+	arguments to track usage.
+
+	(New.DoEmit): Call AddressOf with new arguments.
+
+	(Unary.Emit): Adjust AddressOf call.
+
+2002-03-01  Ravi Pratap  <ravi@ximian.com>
+
+	* cs-parser.jay (member_access): Change the case for pre-defined types
+	to use a MemberAccess instead of a SimpleName. Thanks to Felix again for 
+	this suggestion.
+
+	* class.cs (Operator::Emit): If we are abstract or extern, we don't have
+	a method body.
+
+	* attribute.cs (CheckAttribute, ApplyAttribute): Ensure that we treat operators
+	essentially like methods and apply attributes like MethodImplOptions to them too.
+
+	* ecore.cs (SimpleName.SimpleNameResolve): Perform a check on ec.TypeContainer.TypeBuilder
+	not being null.
+
+	* codegen.cs (EmitContext): The constructor now takes in an extra argument specifying the
+	DeclSpace as the distinction is important. We provide sane defaults as usually the TypeContainer
+	is the DeclSpace.
+
+	* Update code everywhere accordingly.
+
+	* ecore.cs : Change references to ec.TypeContainer to ec.DeclSpace where appropriate.
+
+	* cs-parser.jay (enum_declaration): Set the current namespace of the enum.
+
+2002-02-28  Ravi Pratap  <ravi@ximian.com>
+
+	* rootcontext.cs (LookupType): As we cycle through the chain of namespaces
+	try performing lookups against those instead of jumping straight into using
+	the 'using' clauses.
+
+	(ImplicitParent): Add. Thanks to Felix Arrese-Igor for this idea.
+
+	(LookupType): Perform lookups in implicit parents too.
+
+	* class.cs (GetInterfaceOrClass): Modify to perform the exact same lookup
+	sequence as RootContext.LookupType. 
+
+	* rootcontext.cs (NamespaceLookup): Split out code from LookupType which tries 
+	the various cases of namespace lookups into this method.
+
+2002-03-01  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay: Add support for [Attribute ()] (empty arguments
+	in positional arguments)
+
+	* class.cs (Operator): Update the AllowedModifiers to contain
+	extern. 
+
+	* cs-parser.jay: Update operator declaration to allow for the
+	operator body to be empty.
+
+	* cs-tokenizer.cs: Added '\u' unicode support in strings and hex
+	values. 
+
+2002-02-27  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Method.Emit): Label parameters.
+
+	* driver.cs: Return 1 or 0 as the program exit code.
+
+2002-02-26  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs: Special case the `null' object when trying to
+	auto-compute the type, as anything can be explicitly converted to
+	that. 
+
+	* ecore.cs (Expression.ConvertExplicit): Bug fix, thanks for
+	spotting this Paolo.
+
+	(Expression.ImplicitNumericConversion): Perform comparissions of
+	the type using the underlying type in the case of an enumeration
+	rather than using the enumeration type for the compare.
+
+	Cope with the underlying == type case, which is not possible to
+	catch before. 
+
+	(Expression.ConvertNumericExplicit): Perform comparissions of
+	the type using the underlying type in the case of an enumeration
+	rather than using the enumeration type for the compare.
+
+	* driver.cs: If the user does not supply an extension, assume .exe
+
+	* cs-parser.jay (if_statement): Rewrote so that we can track the
+	location for the if statement.
+
+	* expression.cs (Binary.ConstantFold): Only concat strings when
+	the operation is "+", not everything ;-)
+
+	* statement.cs (Statement.EmitBoolExpression): Take a location
+	argument. 
+	(If, While, Do): Track location.
+
+	* expression.cs (Binary.ResolveOperator): In the object + string
+	case, I was missing a call to ConvertImplicit
+
+2002-02-25  Ravi Pratap  <ravi@ximian.com>
+
+	* parameter.cs (Parameter.ExternalType): Take in extra DeclSpace and
+	Location arguments. Ensure we use RootContext.LookupType to do our work
+	and not try to do a direct Type.GetType and ModuleBuilder.GetType
+
+	* interface.cs (PopulateMethod): Handle the type of the parameter being
+	null gracefully.
+
+	* expression.cs (Invocation.BetterFunction): Handle the case when we 
+	have a params method with no fixed arguments and a call is made with no
+	arguments.
+
+2002-02-25  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-tokenizer.cs: Add support for the quote-escape-sequence in
+	the verbatim-string-literal
+
+	* support.cs (InternalParameters.ParameterModifier): handle null
+	fixed parameters.
+	(InternalParameters.ParameterType): ditto.
+
+	* parameter.cs (VerifyArgs): Also check if the fixed parameter is
+	duplicating the name of the variable parameter.
+	(GetParameterByName): Fix bug where we were not looking up array
+	paramters if they were the only present (thanks Paolo!).
+	(GetParameterInfo): We only have an empty set of types if both
+	fixed and array are set to null.
+	(GetParameterInfo-idx): Handle FixedParameter == null
+
+	* cs-parser.jay: Handle the case where there is no catch
+	statements (missing null test).
+
+2002-02-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs (MainDriver): Be conservative on our command line
+	handling.
+
+	Catch DirectoryNotFoundException when calling GetFiles.
+	
+	(SplitPathAndPattern): Used to split the input specification into
+	a path and a pattern that we can feed to Directory.GetFiles.
+
+2002-02-21  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (Fixed): Implement the last case of the Fixed
+	statement (string handling).
+
+	* expression.cs (StringPtr): New class used to return a char * to
+	a string;  Used by the Fixed statement.
+
+	* typemanager.cs: Add char_ptr_type.  Add get_OffsetToStringData method.
+
+	* expression.cs (Binary.ResolveOperator): Remove redundant
+	MemberLookup pn parent type.
+	Optimize union call, we do not need a union if the types are the same.
+	(Unary.ResolveOperator): REmove redundant MemberLookup on parent
+	type.
+
+	Specialize the use of MemberLookup everywhere, instead of using
+	the default settings. 
+
+	(StackAlloc): Implement stackalloc keyword.
+
+	* cs-parser.jay: Add rule to parse stackalloc.
+	
+	* driver.cs: Handle /h, /help, /?
+
+	* expression.cs (MakeByteBlob): Removed the hacks we had in place
+	before we supported unsafe code.

+	Handle pointer comparission.
+	(ArrayPtr): Utility expression class that is used to take the
+	address of an array.

+	(ElementAccess): Implement array access for pointers
+	
+	* statement.cs (Fixed): Implement fixed statement for arrays, we
+	are missing one more case before we are done.
+
+	* expression.cs (Indirection): Implement EmitAssign and set the
+	ExprClass to Variable.  This allows pointer dereferences to be
+	treated as variables, and to have values assigned to them.
+	
+	* ecore.cs (Expression.StoreFromPtr): New utility function to
+	store values dereferencing.
+
+2002-02-20  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (Binary.ResolveOperator): Ensure that we are
+	not trying to operate on a void type - this fixes the reported
+	bug.
+
+	* decl.cs (CheckMethodAgainstBase): Do not allow overriding if
+	the parent implementation is sealed.
+
+	* ../errors/cs0239.cs : Add.
+
+	* attribute.cs (ApplyAttributes): Handle Modulebuilders too.
+
+	* typemanager.cs (unverifiable_code_type): Corresponds to 
+	System.Security.UnverifiableCodeAttribute. We need to emit this for modules
+	which have unsafe code in them.
+
+	* rootcontext.cs (EmitCode): Emit the above attribute when we are in an 
+	unsafe context.
+
+2002-02-19  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-tokenizer.cs: Add support for @"litreal strings"
+
+	Make tokenizer accept pre-processor directives
+	on any column (remove the old C-like limitation).

+
+	* expression.cs (Indirection): New helper class.  Unary will
+	create Indirection classes to be able to implement the
+	IMemoryLocation interface on it.
+
+2002-02-16  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay (fixed_statement): reference the right statement.
+
+	* statement.cs (Fixed.Emit): Finish implementing the fixed
+	statement for the &x case.
+
+2002-02-14  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Property.Define, Method.Define): Remove newslot when
+	`implementing'.  
+
+	* modifiers.cs: My use of NewSlot when `Abstract' was set was
+	wrong.  NewSlot should only be used if the `new' keyword is present.
+
+	* driver.cs (GetSystemDir): Use CodeBase instead of FullName for
+	locating our system dir.  Sorry about this.
+
+2002-02-13  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs (GetSystemDir): Compute correctly the location of our
+	system assemblies.  I was using the compiler directory instead of
+	the library directory.
+
+2002-02-13  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (BetterFunction): Put back in what Miguel commented out
+	since it is the correct fix. The problem is elsewhere ;-)
+
+	(IsParamsMethodApplicable): Fix bug where we were not checking that the fixed
+	parameters of the parms method are themselves compatible or not !
+
+	(StandardConversionExists): Fix very dangerous bug where we were forgetting
+	to check that a class implements an interface before saying that an implicit
+	conversion was allowed. Use ImplementsInterface to do the checking.
+
+2002-02-13  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Method.Define): Track whether we are an explicit
+	implementation or not.  And only call DefineMethodOverride if we
+	are an explicit implementation.
+
+	(Property.DefineMethod): Ditto.
+
+2002-02-11  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (BetterFunction): Catch hideous bug which was
+	 preventing us from detecting ambiguous calls due to implicit casts i.e
+	cs0121.
+
+2002-01-29  Miguel de Icaza  <miguel@ximian.com>
+
+	* support.cs (Pair): Remove un-needed method.  I figured why I was
+	getting the error in cs-parser.jay, the variable in a foreach loop
+	is readonly, and the compiler does not really treat this as a variable.
+
+	* cs-parser.jay (fixed_statement): Fix grammar.  Use ASSIGN
+	instead of EQUALS in grammar.  
+
+	* typemanager.cs (VerifyUnmanaged): Report correct error (208)
+
+	* expression.cs (Unary.DoResolve): Check whether the argument is
+	managed or not.
+
+2002-01-28  Miguel de Icaza  <miguel@ximian.com>
+
+	* support.cs: Api for Pair to set a value.  Despite the fact that
+	the variables are public the MS C# compiler refuses to compile
+	code that accesses the field if the variable is part of a foreach
+	statement. 
+
+	* statement.cs (Fixed): Begin implementation of the fixed
+	statement.
+
+	(Block.AddVariable): Return the VariableInfo on success and null
+	on failure instead of true/false. 
+
+	* cs-parser.jay (foreach): Catch errors on variables already
+	defined (we were ignoring this value before) and properly unwind
+	the block hierarchy
+
+	(fixed_statement): grammar for the fixed statement.
+
+2002-01-25  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (UnaryMutator.IsIncrementableNumber): Allow also

+	on safe contexts.
+
+	(Unary): Implement indirection.
+

+	use in non-unsafe context).
+
+	(SimpleName.DoResolve): Check for pointers in field access on safe
+	contexts. 
+
+	(Expression.LoadFromPtr): Factor the load-indirect code in this
+	function.  This was duplicated in UnboxCast and ParameterReference
+
+2002-01-24  Miguel de Icaza  <miguel@ximian.com>

+
+	* cs-parser.jay (non_expression_type): Add productions for pointer
+	casts. 
+
+	* expression.cs (Invocation.EmitCall): Remove chunk of buggy
+	code.  We should not use force into static mode if the method is
+	not virtual.  Fixes bug in MIS
+
+	* statement.cs (Do.Emit, While.Emit, For.Emit,
+	Statement.EmitBoolExpression): Add support to Do and While to
+	propagate infinite loop as `I do return' semantics.
+
+	Improve the For case to also test for boolean constants.
+
+	* attribute.cs (Attribute.ApplyAttributes): Add ParameterBuilder
+	to the list of attributes we can add.
+
+	Remove `EmitContext' argument.
+
+	* class.cs (Method.Define): Apply parameter attributes.
+	(Constructor.Define): Apply parameter attributes.
+	(MethodCore.LabelParameters): Move here the core of labeling
+	parameters. 
+
+	* support.cs (ReflectionParameters.ParameterModifier,
+	InternalParameters.ParameterModifier): Use IsByRef on the type and
+	only return the OUT bit for these parameters instead of in/out/ref
+	flags.
+
+	This is because I miss-understood things.  The ParameterInfo.IsIn
+	and IsOut represent whether the parameter has the [In] and [Out]
+	attributes set.  
+
+2002-01-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (FieldExpr.Emit): Release temporaries.
+
+	* assign.cs (LocalTemporary.Release): new function.
+
+	* codegen.cs (EmitContext.GetTemporaryStorage,
+	EmitContext.FreeTemporaryStorage): Rework the way we deal with
+	temporary storage.  Now we can "put back" localbuilders when we
+	are done with them
+
+2002-01-21  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (FieldExpr.Emit): Handle initonly fields specially: we
+	need to make a copy of the variable to generate verifiable code.
+
+2002-01-19  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs: Compute dynamically the system directory.
+
+	* ecore.cs (CopyNewMethods): reworked, exposed, made public.
+	Slower, but more generally useful.  Used by the abstract
+	registering implementation. 
+
+	* expression.cs (ResolveMemberAccess): Reorder the way we evaluate
+	the rules for the special rule on Type/instances.  First check if
+	we have the same name, and if so, try that special static path
+	rather than the instance path.
+	
+2002-01-18  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay: Emit 642 (warning: possible empty statement) for
+	for, while and if.

+	* class.cs (TypeBuilder.DefineType): Do not allow inheritance from
+	Enum, ValueType, Delegate or Array for non-corlib compiles.
+
+	* cs-tokenizer.cs: Catch long identifiers (645)
+
+	* typemanager.cs (IndexerPropetyName): Ravi never tested this
+	piece of code.
+
+	* class.cs (TypeContainer.RegisterRequiredImplementations): Bug
+	fix, we were returning too early, so we were not registering
+	pending methods from abstract classes.
+
+	Do not register pending methods if the class is abstract.
+
+	* expression.cs (Conditional.DoResolve): Report circular implicit
+	conversions when we neecd to compute it for conditional
+	expressions. 
+

+
+	* ecore.cs (FieldExpr): For now in AddressOf mark as assigned and
+	read. 
+
+2002-01-18  Nick Drochak  <ndrochak@gol.com>
+
+	* makefile: remove path to beta2 csc.exe.  path to csc.exe must be in PATH instead.
+
+2002-01-17  Miguel de Icaza  <miguel@ximian.com>
+
+	* interface.cs: (PopulateMethod): Check for pointers being defined
+	only if the unsafe context is active.
+	(PopulateProperty): ditto.
+	(PopulateIndexer): ditto.
+
+	* class.cs (Method, Method.Define): Allow `unsafe' modifier to be
+	specified.  If pointers are present, make sure that they are
+	present in an unsafe context.
+	(Constructor, Constructor.Define): ditto.
+	(Field, Field.Define): ditto.
+	(Property, Property.Define): ditto.
+	(Event, Event.Define): ditto.
+
+	* interface.cs (Interface.GetInterfaceTypeByName): Only lookup the
+	hashtable if there are classes or structs defined.
+
+	* expression.cs (LocalVariableReference.DoResolve): Simplify this
+	code, as the constant resolution moved.
+
+	* statement.cs (Block.EmitMeta): Resolve all constants as we emit
+	the metadata, so we can flag error 133. 
+
+	* decl.cs (MemberCore.UnsafeOK): New function to test that a
+	pointer is being declared in an unsafe context.
+
+2002-01-16  Miguel de Icaza  <miguel@ximian.com>

+	Report error 227 for Unsafe use.
+
+	* typemanager.cs: Remove IsPointerType, we should be using Type.IsPointer
+
+	* statement.cs (For.Emit): If the test is null, then report that
+	we do `return', as we wont reach anything afterwards.
+
+	(Switch.SwitchGoverningType): Track the expression that matched
+	the conversion.
+
+	* driver.cs: Allow negative numbers as an error code to flag.
+
+	* cs-parser.jay: Handle 1551.

+
+2002-01-15  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay: Report 1518 (type declaration can only contain
+	class, struct, interface, enum or delegate)

+	to need a lot.
+
+	* ecore.cs (ImplicitReferenceConversion): A pointer type cannot be cast to
+	the object type, so we take care of that.
+
+	* expression.cs (FullMethodDesc): Also include the return type in descriptions.
+	
+	* support.cs (ParameterDesc): Fix minor bug which was causing params tags to be
+	added to non-params parameters :-)
+
+	* typemanager.cs (CSharpName): Include 'void' type too.	
+
+	(void_ptr_type): Include in the set of core types.
+

+	duplicating code.
+
+	(ConvertImplicitStandard): Handle standard implicit pointer conversions when we have 
+	an unsafe context.
+
+	* cs-parser.jay (local_variable_pointer_type): Add support for 'void *' as I had 
+	completely forgotten about it.
+
+2002-01-10  Ravi Pratap  <ravi@ximian.com>
+
+	* cs-parser.jay (pointer_type): Add. This begins our implementation
+	of parsing rules for unsafe code.
+
+	(unsafe_statement): Implement.
+
+	(embedded_statement): Modify to include the above.
+
+	* statement.cs (Unsafe): Implement new class for unsafe blocks.
+
+	* codegen.cs (EmitContext.InUnsafe): Add. This determines
+	if the current context is an unsafe one.
+
+	* cs-parser.jay (local_variable_pointer_type): Since local variable types
+	are handled differently, we need separate rules for them.
+
+	(local_variable_declaration): Update to use local_variable_pointer_type
+	to allow variable declarations of unmanaged pointer types.
+
+	* expression.cs (Unary.ResolveOperator): Ensure that the '&' operator is used only
+	in unsafe contexts.
+
+	* ../errors/cs0214.cs : Add.
+
+2002-01-16  Nick Drochak  <ndrochak@gol.com>
+
+	* makefile: remove 'response' file when cleaning.
+
+2002-01-15  Miguel de Icaza  <miguel@ximian.com>

+	* cs-parser.jay: Report 1524.
+
+2002-01-14  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs (RegisterMethod): drop checking if we have
+	registered this from here
+
+2002-01-12  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Method.EmitDestructor): Implement calling our base
+	destructor. 
+
+	* statement.cs (Try.Emit): Fix to reset the InFinally to the old
+	value of InFinally.
+
+	* codegen.cs (EmitContext.EmitTopBlock): Destructors will call
+	this routine and will wrap the call in a try/catch block.  Deal
+	with the case.
+
+2002-01-11  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (Expression.MemberLookup): instead of taking a
+	parameter `same_type' that was used to tell whether we could
+	access private members we compute our containing type from the
+	EmitContext.
+
+	(FieldExpr): Added partial support for volatile fields.  This does
+	not work for volatile fields exposed from assemblies, as I can not
+	figure out how to extract the modreq from it.
+
+	Updated all the source files to use this.
+
+	* codegen.cs (EmitContext): Compute ContainerType ahead of time,
+	because it is referenced by MemberLookup very often. 
+
+2002-01-09  Ravi Pratap  <ravi@ximian.com>
+
+	* typemanager.cs (IndexerPropertyName): If we have a TypeBuilder, use
+	TypeBuilder.GetCustomAttributes to retrieve what we need.
+
+	Get rid of redundant default_member_attr_type as this is the same as
+	default_member_type which already exists.
+
+	* interface.cs, attribute.cs : Update accordingly.
+	
+2002-01-08  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs: Enable IndexerPropertyName again.  It does not
+	work for TYpeBuilders though.  Ravi, can you please fix this?
+
+	* cs-tokenizer.cs: Accept _ as a name in pp-expressions.
+
+	* expression.cs (Argument.Emit): Handle the case of ref objects
+	being passed to ref functions;  
+
+	(ParameterReference.EmitLoad): Loads the content of the pointer
+	without dereferencing.
+
+2002-01-07  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-tokenizer.cs: Implemented the pre-processing expressions.
+
+2002-01-08  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (Indexer.DefineMethod): Incorporate the interface
+	type in the name of the method if we are doing explicit interface
+	implementation.
+
+	* expression.cs (ConversionExists): Remove as it is completely obsolete.
+
+	(BetterConversion): Fix extremely trivial bug where we were referring to
+	ConversionExists instead of StandardConversionExists ! Hooray, things are fine
+	again !
+
+	* ../errors/bug16.cs : Add although we have fixed it.
+
+2002-01-07  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (BaseIndexer): Begin implementation.
+
+	* class.cs (TypeContainer.IsInterfaceMethod): Bug fix.
+
+	* cs-parser.jay (indexer_declarator): Use qualified_identifier
+	production directly to remove a shift/reduce, and implement
+	explicit interface implementation.
+
+	* cs-tokenizer.cs: Fix tokenizer, it was consuming one extra char
+	after a floating point suffix.
+
+	* expression.cs (DoNumericPromotions): Improved the conversion for
+	uint/uint.  If we have a constant, we avoid doing a typecast to a
+	larger type.
+
+	* class.cs (Indexer): Implement explicit interface implementation
+	for indexers.
+	
+Sat Jan 5 16:08:23 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* class.cs: make the default instance constructor public and hidebysig.
+
+2001-01-03  Ravi Pratap  <ravi@ximian.com>
+
+	* interface.cs (EmitDefaultMemberAttr): Make this helper method static
+	so we can call it from elsewhere.
+
+	* class.cs (TypeContainer.Emit): Emit the attribute here too. The rule is that
+	we emit it internally if the class has a defined indexer; otherwise the user
+	emits it by decorating the class definition with the DefaultMemberAttribute.
+
+	* attribute.cs (ApplyAttributes): Perform checks to see that the DefaultMember
+	attribute is not used on a type which defines an indexer.
+
+	* cs-tokenizer.cs (get_cmd_arg): Ensure we trim whitespace and also include the tab
+	character when we skip whitespace.
+
+	* ../errors/cs0646.cs : Add.
+
+2002-01-03  Miguel de Icaza  <miguel@ximian.com>
+
+	* ecore.cs (SimpleName.ResolveSimpleName): Report error 120
+	again. 
+
+	* makefile: Add practical target `mcs3.exe' which builds the third
+	generation compiler. 
+
+	* expression.cs (New): Fix structures constructor calling.
+
+	* class.cs (Property, Method, Indexer): Emit Final flag on the
+	method if we are an interface implementation and we are not
+	abstract. 
+
+	* ecore.cs (PropertyExpr): New public field `IsBase', tells
+	whether this property is referencing a `base' method.
+
+	* expression.cs (Invocation.EmitCall): take an extra argument:
+	is_base, this is used to determine whether the `call' or
+	`callvirt' opcode should be used.
+
+	
+	* delegate.cs: update EmitCall.
+
+	* class.cs (Method.Define): Set NewSlot for the cases where we are
+	not implementing an interface method.
+
+	(Property.Define): ditto.
+
+2002-01-02  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-tokenizer.cs: (Tokenizer.escape): Escape '\r' as '\r' not as
+	'r'.  Allows mcs to parse itself fully.
+
+2002-01-02  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (ArrayCreation.num_automatic_initializers): Keep track
+	of the number of initializers that require the InitializeArray method.
+
+	(CheckIndices): Store the Expression in all cases - not the plain value. Also
+	update the above field where necessary.
+
+	(MakeByteBlob): Update accordingly.
+
+	(DoEmit): Call EmitStaticInitializers only if the number of initializers is 
+	greater than 2.
+
+	(EmitDynamicInitializers): Update in accordance with the new optimization.
+
+	(ArrayAccess.EmitStoreOpcode): Include char type along with short and ushort - the
+	same OpCode applies.
+
+	* cs-parser.jay : Fix some glaring errors I introduced.
+
+2002-01-01  Ravi Pratap  <ravi@ximian.com> 
+
+	* parameters.cs (AddVariable, AddConstant): Pass in current_local_parameters
+	so that we can check for name clashes there too.
+
+	* typemanager.cs (default_member_attr_type): The attribute that we need to emit
+	for interface indexers.
+
+	* interfaces.cs (Define): Emit the default member attribute.
+
+	* expression.cs (MakeByteBlob): Fix extremely trivial bug where the wrong
+	variable was being referred to while setting the value ;-)
+
+2002-01-01  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (MakeByteBlob): Optimize: we do not need to fill
+	byte-by-byte information when we know the data is zero.
+
+	Make the block always a multiple of 4, because
+	DefineInitializedData has a bug.
+
+	* assign.cs: Fix, we should assign from the temporary, not from
+	the source. 
+
+	* expression.cs (MakeByteBlob): Fix my incorrect code.
+
+2001-12-31  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs (EnumToUnderlying): This function is used to get
+	the underlying type from an enumeration, because it does not
+	always work. 
+
+	* constant.cs: Use the I4_S form for values between -128 and 127.
+
+	* statement.cs (Block.LookupLabel): Looks up a label.
+	(Block): Drop support for labeled blocks.
+
+	(LabeledStatement): New kind of statement that represents a label
+	only.
+
+	(Goto): Finally implement this bad boy.
+	
+	* cs-parser.jay: Update to reflect new mechanism to implement
+	labels.
+
+2001-12-30  Miguel de Icaza  <miguel@ximian.com>
+
+	* codegen.cs (EmitContext.This): a codegen property that keeps the
+	a single instance of this instead of creating many different this
+	instances. 
+
+	* delegate.cs (Delegate.DoResolve): Update to use the property;
+
+	* ecore.cs (SimpleName.SimpleNameResolve): Ditto
+
+	* expression.cs (BaseAccess.DoResolve): Ditto.
+
+2001-12-29  Ravi Pratap  <ravi@ximian.com>
+
+	* typemanager.cs (methodimpl_attr_type): Add to hold the type
+	corresponding to System.Runtime.CompilerServices.MethodImplAttribute.
+
+	(InitCoreTypes): Update accordingly.
+
+	* attribute.cs (Resolve): Remember if the attribute is a MethodImplAttribute
+	so we can quickly store the state.
+
+	(ApplyAttributes): Set the correct implementation flags
+	for InternalCall methods.
+
+2001-12-29  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (EmitCall): if a method is not virtual, then do
+	not use callvirt on it.
+
+	(ArrayAccess.EmitAssign): storing non-builtin value types (ie,
+	user defined stuff) requires the use of stobj, which takes an
+	address on the stack instead of an array and an index.  So emit
+	the Ldelema operation for it.
+
+	(EmitStoreOpcode): Use stobj for valuetypes.
+
+	(UnaryMutator.EmitCode): Use the right 1 value depending on
+	whether we are dealing with int64/uint64, float or doubles.
+
+	* class.cs (TypeContainer.AddConstructor): Fix the logic to define
+	constructors that I implemented last night.
+
+	(Constructor.IsDefault): Fix to work properly for static
+	constructors.
+
+	* cs-parser.jay (CheckDef): report method signature errors.
+	Update error number 103 to be 132.
+
+	* decl.cs: New AdditionResult enumeration value: MethodExists.
+	Although we do this check for methods later on in the semantic
+	analysis, catching repeated default constructors is so easy that
+	we catch these here. 
+	
+	* expression.cs (Binary.DoNumericPromotions): Fix the uint64 type
+	promotions code.
+
+	(ParameterReference.EmitAssign, Emit): handle
+	bools as bytes.
+
+	(ArrayAccess.EmitLoadOpcode): Handle bool type here.
+	(ArrayAccess.EmitStoreOpcode): ditto.
+
+	* cs-tokenizer.cs (is_punct): Eliminated empty computation.
+
+	* expression.cs (MakeByteBlob): Complete all the missing types
+	(uint, short, ushort, byte, sbyte)
+
+	* class.cs: Only init instance field initializers on instance
+	constructors. 
+
+	Rename `constructors' to instance_constructors. 
+
+	(TypeContainer.AddConstructor): Only add constructors to the list
+	if it is not static.
+
+	Make sure that we handle default_static_constructor independently
+	everywhere where we handle instance_constructors
+
+2001-12-28  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs: Do not lookup or create a base initializer for a
+	static constructor.
+
+	(ConstructorInitializer.Resolve): use the proper type to lookup
+	for constructors.
+
+	* cs-parser.jay: Report error 1585 (modifiers between type and name).
+
+	* enum.cs, interface.cs: Remove CloseType, this is taken care by
+	in DeclSpace. 
+
+	* decl.cs: CloseType is now an virtual method, the default
+	implementation just closes this type.
+	
+2001-12-28  Ravi Pratap  <ravi@ximian.com>
+
+	* attribute.cs (DefinePInvokeMethod): Set the implementation flags
+	to PreserveSig by default. Also emit HideBySig on such methods.
+
+	Basically, set the defaults to standard values.
+
+	* expression.cs (Invocation.BetterFunction): We need to make sure that for each
+	argument, if candidate is better, it can't be worse than the best !
+
+	(Invocation): Re-write bits to differentiate between methods being
+	applicable in their expanded form and their normal form - for params
+	methods of course.
+
+	Get rid of use_standard everywhere as only standard conversions are allowed
+	in overload resolution. 
+
+	More spec conformance.
+	
+2001-12-27  Miguel de Icaza  <miguel@ximian.com>
+
+	* driver.cs: Add --timestamp, to see where the compiler spends
+	most of its time.
+
+	* ecore.cs (SimpleName.DoResolve): Do not create an implicit
+	`this' in static code.
+
+	(SimpleName.DoResolve): Implement in terms of a helper function
+	that allows static-references to be passed upstream to
+	MemberAccess.
+
+	(Expression.ResolveWithSimpleName): Resolve specially simple
+	names when called by MemberAccess to implement the special
+	semantics. 
+
+	(Expression.ImplicitReferenceConversion): Handle conversions from
+	Null to reference types before others, as Null's type is
+	System.Object. 
+
+	* expression.cs (Invocation.EmitCall): Handle the special case of
+	calling methods declared on a reference type from a ValueType
+	(Base classes System.Object and System.Enum)
+
+	(MemberAccess.Resolve): Only perform lookups on Enumerations if
+	the left hand side is a TypeExpr, not on every enumeration. 
+
+	(Binary.Resolve): If types are reference types, then do a cast to
+	object on operators != and == of both arguments.
+	
+	* typemanager.cs (FindMembers): Extract instance and static
+	members if requested.
+
+	* interface.cs (PopulateProperty): Use void_type instead of null
+	as the return type for the setter method.
+
+	(PopulateIndexer): ditto.
+
+2001-12-27  Ravi Pratap  <ravi@ximian.com>
+
+	* support.cs (ReflectionParameters): Fix minor bug where we
+	were examining the wrong parameter for the ParamArray attribute.
+
+	Cope with requests for the type of the parameter at position
+	greater than the params parameter's. We now return the element
+	type of the params array as that makes more sense.
+
+	* expression.cs (Invocation.IsParamsMethodApplicable): Update 
+	accordingly as we no longer have to extract the element type
+	ourselves.
+
+	(Invocation.OverloadResolve): Update.
+
+2001-12-27  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (Foreach.GetEnumeratorFilter): Do not compare
+	against IEnumerator, test whether the return value is a descendant
+	of the IEnumerator interface.
+
+	* class.cs (Indexer.Define): Use an auxiliary method to implement
+	the other bits of the method definition.  Begin support for
+	explicit interface implementation.
+
+	(Property.DefineMethod): Use TypeManager.void_type instead of null
+	for an empty return value.
+
+2001-12-26  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (MemberAccess.ResolveMemberAccess): if we are
+	dealing with a FieldExpr which is composed of a FieldBuilder, in
+	the code path we did extract the constant, but we should have
+	obtained the underlying value to be able to cast it (otherwise we
+	end up in an infinite loop, this is what Ravi was running into).
+
+	(ArrayCreation.UpdateIndices): Arrays might be empty.
+
+	(MemberAccess.ResolveMemberAccess): Add support for section
+	14.5.4.1 that deals with the special case of E.I when E is a type
+	and something else, that I can be a reference to a static member.
+
+	(ArrayCreation.MakeByteBlob): It is not an error to not be able to
+	handle a particular array type to create byte blobs, it is just
+	something we dont generate byteblobs for.
+
+	* cs-tokenizer.cs (get_cmd_arg): Ignore \r in commands and
+	arguments. 
+
+	* location.cs (Push): remove the key from the hashtable that we
+	are about to add.   This happens for empty files.
+
+	* driver.cs: Dispose files after we have parsed them.
+
+	(tokenize): new function that only runs the tokenizer on its
+	input, for speed testing.
+
+2001-12-26  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (Event.Define): Define the private field only if there
+	are no accessors defined.
+
+	* expression.cs (ResolveMemberAccess): If there is no associated
+	field with the event, that means we have an event defined with its
+	own accessors and we should flag error cs0070 since transforming
+	ourselves into a field is not valid in that case.
+
+	* ecore.cs (SimpleName.DoResolve): Same as above.
+
+	* attribute.cs (DefinePInvokeMethod): Set the default calling convention
+	and charset to sane values.
+
+2001-12-25  Ravi Pratap  <ravi@ximian.com>
+
+	* assign.cs (DoResolve): Perform check on events only if they 
+	are being accessed outside the declaring type.
+
+	* cs-parser.jay (event_declarations): Update rules to correctly
+	set the type of the implicit parameter etc.
+
+	(add_accessor, remove_accessor): Set current local parameters.
+
+	* expression.cs (Binary): For delegate addition and subtraction,
+	cast the return value from the method into the appropriate delegate
+	type.
+
+2001-12-24  Ravi Pratap  <ravi@ximian.com>
+
+	* typemanager.cs (RegisterDelegateData, GetDelegateData): Get rid
+	of these as the workaround is unnecessary.
+
+	* delegate.cs (NewDelegate.DoResolve): Get rid of bits which registered
+	delegate data - none of that is needed at all.
+
+	Re-write bits to extract the instance expression and the delegate method
+	correctly.
+
+	* expression.cs (Binary.ResolveOperator): Handle the '-' binary operator 
+	on delegates too.
+
+	* attribute.cs (ApplyAttributes): New method to take care of common tasks
+	of attaching attributes instead of duplicating code everywhere.
+
+	* everywhere : Update code to do attribute emission using the above method.
+
+2001-12-23  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (IsParamsMethodApplicable): if there are not
+	parameters, return immediately.
+
+	* ecore.cs: The 0 literal can be implicity converted to an enum
+	type. 
+
+	(SimpleName.DoResolve): First lookup the type, then lookup the
+	members. 
+
+	(FieldExpr.Emit): If the InstanceExpression is a ValueType, we
+	want to get its address.  If the InstanceExpression is not
+	addressable, store the result in a temporary variable, then get
+	the address of it.
+
+	* codegen.cs: Only display 219 errors on warning level or above. 
+
+	* expression.cs (ArrayAccess): Make it implement the
+	IMemoryLocation interface.
+
+	(Binary.DoResolve): handle the operator == (object a, object b)
+	and operator != (object a, object b) without incurring into a
+	BoxedCast (because 5 != o should never be performed).
+
+	Handle binary enumerator operators.
+
+	(EmitLoadOpcode): Use Ldelema if the object we are loading is a
+	value type, otherwise use Ldelem_ref.
+
+	Use precomputed names;
+
+	(AddressOf): Implement address of
+
+	* cs-parser.jay (labeled_statement): Fix recursive block
+	addition by reworking the production.
+
+	* expression.cs (New.DoEmit): New has a special case:
+		
+		 If we are dealing with a ValueType, we have a few
+		 situations to deal with:
+		
+		    * The target of New is a ValueType variable, that is
+		      easy, we just pass this as the variable reference
+		
+		    * The target of New is being passed as an argument,
+		      to a boxing operation or a function that takes a
+		      ValueType.
+		
+		      In this case, we need to create a temporary variable
+		      that is the argument of New.
+
+
+2001-12-23  Ravi Pratap  <ravi@ximian.com>
+
+	* rootcontext.cs (LookupType): Check that current_type is not null before
+	going about looking at nested types.
+
+	* ecore.cs (EventExpr.EmitAddOrRemove): Rename from EmitAssign as we do
+	not implement the IAssignMethod interface any more.
+
+	* expression.cs (MemberAccess.ResolveMemberAccess): Handle EventExprs specially
+	where we tranform them into FieldExprs if they are being resolved from within
+	the declaring type.
+
+	* ecore.cs (SimpleName.DoResolve): Do the same here.
+
+	* assign.cs (DoResolve, Emit): Clean up code considerably. 
+
+	* ../errors/bug10.cs : Add.
+
+	* ../errors/cs0070.cs : Add.
+
+	* typemanager.cs : Use PtrHashtable for Delegate data hashtable etc.

+
+	* statement.cs (SwitchLabel): Convert the value we are using as a
+	key before looking up the table.
+
+2001-12-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* codegen.cs (EmitTopBlock): Require a Location argument now.
+
+	* cs-parser.jay (constructor_declarator): We need to setup
+	current_local_parameters before we parse the
+	opt_constructor_initializer, to allow the variables to be bound
+	to the constructor arguments.
+
+	* rootcontext.cs (LookupType): First lookup nested classes in our
+	class and our parents before we go looking outside our class.
+
+	* expression.cs (ConstantFold): Extract/debox the values at the
+	beginnning. 
+
+	* rootcontext.cs (EmitCode): Resolve the constants first before we
+	resolve the types.  This is not really needed, but it helps debugging.
+
+	* statement.cs: report location.
+	
+	* cs-parser.jay: pass location to throw statement.
+
+	* driver.cs: Small bug fix.
+
+	* report.cs: Updated format to be 4-zero filled digits.

+	* ecore.cs (EventExpr.EmitAssign): Implement the IAssignMethod
+	interface.
+
+	(SimpleName.MemberStaticCheck): Include check for EventExpr.
+
+	(EventExpr): Set the type in the constructor itself since we 
+	are meant to be born fully resolved.
+
+	(EventExpr.Define): Revert code I wrote earlier.
+		
+	* delegate.cs (NewDelegate.Resolve): Handle the case when the MethodGroup's
+	instance expression is null. The instance expression is a This in that case
+	or a null, depending on whether it is a static method or not.
+
+	Also flag an error if the reference to a method is ambiguous i.e the MethodGroupExpr
+	refers to more than one method.
+
+	* assign.cs (DoResolve): Check whether the event belongs to the same Type container
+	and accordingly flag errors.
+

+	objects, return the actual integral boxed.
+
+	* statement.cs (SwitchLabel): define an ILLabel for each
+	SwitchLabel. 
+	
+	(Switch.CheckSwitch): If the value is a Literal, extract
+	the underlying literal.
+	
+	Also in the unused hashtable we had, add the SwitchLabel so we can
+	quickly look this value up.
+
+	* constant.cs: Implement a bunch of new constants.  Rewrite
+	Literal based on this.  Made changes everywhere to adapt to this.
+	
+	* expression.cs (Expression.MakeByteBlob): Optimize routine by
+	dereferencing array only once, and also copes with enumrations.
+
+	bytes are two bytes wide, not one.
+
+	(Cast): Perform constant conversions.
+	
+	* ecore.cs (TryImplicitIntConversion): Return literals instead of
+	wrappers to the literals here.
+
+	* expression.cs (DoNumericPromotions): long literals can converted
+	to ulong implicity (this is taken care of elsewhere, but I was
+	missing this spot).
+
+	* ecore.cs (Expression.Literalize): Make the return type Literal,
+	to improve type checking.
+
+	* rootcontext.cs: Lookup for nested classes in our class hierarchy.
+
+2001-12-20  Miguel de Icaza  <miguel@ximian.com>
+
+	* literal.cs: Revert code from ravi that checked the bounds.  The
+	bounds are sane by the definition of the type itself. 
+
+	* typemanager.cs: Fix implementation of ImplementsInterface.  We
+	need to actually look up in our parent hierarchy for interfaces
+	implemented. 
+
+	* const.cs: Use the underlying type for enumerations
+
+	* delegate.cs: Compute the basename for the delegate creation,
+	that should fix the delegate test case, and restore the correct
+	Type Lookup semantics in rootcontext
+
+	* rootcontext.cs: Revert Ravi's last patch.  The correct way of
+	referencing a nested type with the Reflection API is using the "+"
+	sign. 
+
+	* cs-parser.jay: Do not require EOF token at the end.
+
+2001-12-20  Ravi Pratap  <ravi@ximian.com>
+
+	* rootcontext.cs (LookupType): Concatenate type names with
+	a '.' instead of a '+' The test suite passes again.
+
+	* enum.cs (Enum.DefineEnum): Set RTSpecialName on the 'value__'
+	field of the enumeration.
+
+	* expression.cs (MemberAccess.ResolveMemberAccess): Add support for
+	the case when the member is an EventExpr.
+
+	* ecore.cs (EventExpr.InstanceExpression): Every event which is not
+	static has an associated instance expression.
+
+	* typemanager.cs (RegisterEvent): The usual workaround, now for events.
+
+	(GetAddMethod, GetRemoveMethod): Workarounds, as usual.
+
+	* class.cs (Event.Define): Register event and perform appropriate checks
+	for error #111.
+
+ 	We define the Add and Remove methods even if the use provides none because
+	in that case, we provide default implementations ourselves.
+
+	Define a private field of the type of the event. This is done by the CSC compiler
+	and we should be doing it too ;-)
+
+	* typemanager.cs (delegate_combine_delegate_delegate, delegate_remove_delegate_delegate):
+	More methods we use in code we generate.
+
+	(multicast_delegate_type, delegate_type): Two separate types since the distinction
+	is important.
+
+	(InitCoreTypes): Update accordingly for the above.
+
+	* class.cs (Event.Emit): Generate code for default accessors that we provide
+
+	(EmitDefaultMethod): Do the job in the above.
+
+	* delegate.cs (DefineDelegate): Use TypeManager.multicast_delegate_type in the 
+	appropriate place.
+
+2001-12-20  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Indexer.Define): Fix bug, we were setting both Get/Set
+	builders even if we were missing one.
+
+	* interface.cs, class.cs, enum.cs: When calling DefineNestedType
+	pass the Basename as our class name instead of the Name.  The
+	basename will be correctly composed for us.
+
+	* parameter.cs (Paramters): Now takes a Location argument.
+
+	* decl.cs (DeclSpace.LookupType): Removed convenience function and
+	make all the code call directly LookupType in RootContext and take
+	this chance to pass the Location information everywhere.
+
+	* Everywhere: pass Location information.
+
+2001-12-19  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (Constructor.Define): Updated way of detecting the
+	length of the parameters.
+
+	(TypeContainer.DefineType): Use basename as the type name for
+	nested types.
+
+	(TypeContainer.Define): Do not recursively define types here, as
+	definition is taken care in order by the RootContext.
+
+	* tree.cs: Keep track of namespaces in a per-file basis.
+
+	* parameter.cs (Parameter.ComputeSignature): Update to use
+	DeclSpace. 
+
+	(Parameters.GetSignature): ditto.
+
+	* interface.cs (InterfaceMethod.GetSignature): Take a DeclSpace
+	instead of a TypeContainer.
+
+	(Interface.SemanticAnalysis): Use `this' instead of our parent to
+	resolve names.  Because we need to be resolve in our context, not
+	our parents.
+	
+	* driver.cs: Implement response files.
+
+	* class.cs (TypeContainer.DefineType): If we are defined, do not
+	redefine ourselves.
+	
+	(Event.Emit): Emit the code for add/remove handlers.
+	(Event.Define): Save the MethodBuilders for add/remove.
+
+	* typemanager.cs: Use pair here too.
+
+	* cs-parser.jay: Replaced use of DictionaryEntry for Pair because
+	DictionaryEntry requires the first argument to be non-null.  
+	
+	(enum_declaration): Compute full name for registering the
+	enumeration.
+	
+	(delegate_declaration): Instead of using
+	formal_parameter_list, use opt_formal_parameter_list as the list
+	can be empty.
+
+	* cs-tokenizer.cs (PropertyParsing): renamed from `properties'
+	(EventParsing): New property that controls whether `add' and
+	`remove' are returned as tokens or identifiers (for events);
+
+2001-12-19  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (Event.Define): Revamp use of EventBuilder completely. We now
+	use MyEventBuilder only and let it wrap the real builder for us.
+
+	(MyEventBuilder): Revamp constructor etc.
+
+	Implement all operations that we perform on EventBuilder in precisely the same
+	way here too.
+
+	(FindMembers): Update to use the EventBuilder member.
+
+	(Event.Emit): Update accordingly.
+
+2001-12-18  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (MyEventBuilder.Set*): Chain to the underlying builder
+	by calling the appropriate methods.
+
+	(GetCustomAttributes): Make stubs as they cannot possibly do anything
+	useful.
+
+	(Event.Emit): Use MyEventBuilder everywhere - even to set attributes.
+
+2001-12-17  Ravi Pratap  <ravi@ximian.com>
+
+	* delegate.cs (Delegate.Populate): Check that the return type
+	and various parameters types are indeed accessible.
+
+	* class.cs (Constructor.Define): Same here.
+
+	(Field.Define): Ditto.
+
+	(Event.Define): Ditto.
+
+	(Operator.Define): Check that the underlying Method defined itself
+	correctly - so it's MethodBuilder should not be null.
+
+	* delegate.cs (DelegateInvocation.DoResolve): Bale out if the type of the Instance
+	expression happens to be null.
+
+	* class.cs (MyEventBuilder): Workaround for SRE lameness. Implement various abstract
+	members but as of now we don't seem to be able to do anything really useful with it.
+
+	(FindMembers): Handle events separately by returning the MyEventBuilder of the event,
+	not the EventBuilder.
+
+2001-12-18  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-tokenizer.cs: Add support for defines.
+	Add support for #if, #elif, #else, #endif
+	
+	(eval_var): evaluates a variable.
+	(eval): stubbed for evaluating functions.
+
+	* cs-parser.jay: Pass the defines information
+
+	* driver.cs: Add --define command line option.
+
+	* decl.cs: Move MemberCore here.
+
+	Make it the base class for DeclSpace.  This allows us to catch and
+	report 108 and 109 for everything now.
+
+	* class.cs (TypeContainer.Define): Extract all the members
+	before populating and emit the warning 108 (new keyword required
+	to override) instead of having each member implement this.
+
+	(MemberCore.Define): New abstract method, we will be using this in
+	the warning reporting engine in Populate.
+	
+	(Operator.Define): Adjust to new MemberCore protocol. 
+
+	* const.cs (Const): This does not derive from Expression, it is a
+	temporary object we use to create fields, it is a MemberCore. 
+
+	* class.cs (Method.Define): Allow the entry point to be in a
+	specific class.
+
+	* driver.cs: Rewrite the argument handler to clean it up a bit.
+
+	* rootcontext.cs: Made it just an auxiliary namespace feature by
+	making everything static.
+
+	* driver.cs: Adapt code to use RootContext type name instead of
+	instance variable.
+
+	* delegate.cs: Remove RootContext argument.
+
+	* class.cs: (Struct, TypeContainer, Class): Remove RootContext
+	argument. 
+
+	* class.cs (Event.Define): The lookup can fail.
+	
+	* cs-tokenizer.cs: Begin implementation of pre-procesor. 
+
+	* expression.cs: Resolve the this instance before invoking the code.
+
+2001-12-17  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay: Add a production in element_access that allows
+	the thing to become a "type" reference.  This way we can parse
+	things like "(string [])" as a type.
+
+	Note that this still does not handle the more complex rules of
+	casts. 
+	
+
+	* delegate.cs (Delegate.Populate): Register the delegage constructor builder here. 
+
+	* ecore.cs: (CopyNewMethods): new utility function used to
+	assemble the list of methods from running FindMembers.
+
+	(MemberLookup): Rework FindMembers so that 
+
+2001-12-16  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (TypeContainer): Remove Delegates who fail to be
+	defined.
+
+	* delegate.cs (Populate): Verify that we dont get null return
+	values.   TODO: Check for AsAccessible.
+
+	* cs-parser.jay: Use basename to emit error 574 (destructor should
+	have the same name as container class), not the full name.
+
+	* cs-tokenizer.cs (adjust_int): Fit the integer in the best
+	possible representation.  
+
+	Also implements integer type suffixes U and L.
+
+2001-12-15  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (ArrayCreation.DoResolve): We need to do the
+	argument resolution *always*.
+
+	* decl.cs: Make this hold the namespace.  Hold the root context as
+	well.
+	(LookupType): Move here.
+
+	* enum.cs, class.cs, interface.cs: Adapt to new hierarchy.
+
+	* location.cs (Row, Name): Fixed the code, it was always returning
+	references to the first file.
+
+	* interface.cs: Register properties defined through interfaces.
+
+	* driver.cs: Add support for globbing on the command line
+
+	* class.cs (Field): Make it derive from MemberCore as well.
+	(Event): ditto.
+
+2001-12-15  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (Event::Define): Check that the type of the event is a delegate
+	type else flag error #66.
+
+	Also, re-use TypeContainer.MethodModifiersValid here too as the rules are the
+	same.
+
+	* attribute.cs (DefinePInvokeMethod): Handle named arguments and process
+	values of EntryPoint, CharSet etc etc.
+
+	Pass in the values to TypeBuilder.DefinePInvokeMethod; determine Type etc neatly.
+
+	* class.cs (FindMembers): If a method is in transit, its MethodBuilder will
+	be null and we should ignore this. I am not sure if this is really clean. Apparently,
+	there's no way of avoiding hitting this because the call is coming from SimpleName.DoResolve,
+	which needs this to do its work.
+
+	* ../errors/cs0066.cs : Add.
+
+2001-12-14  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs: (GetPropertyGetter, GetPropertyGetter): New
+	helper functions.
+
+	* class.cs: (MethodSignature.MethodSignature): Removed hack that
+	clears out the parameters field.
+	(MemberSignatureCompare): Cleanup
+
+	(MemberCore): New base class used to share code between MethodCore
+	and Property.
+
+	(RegisterRequiredImplementations) BindingFlags.Public requires
+	either BindingFlags.Instace or Static.  Use instance here.
+
+	(Property): Refactored code to cope better with the full spec.
+
+	* parameter.cs (GetParameterInfo): Return an empty array instead
+	of null on error.
+
+	* class.cs (Property): Abstract or extern properties have no bodies.
+
+	* parameter.cs (GetParameterInfo): return a zero-sized array.
+
+	* class.cs (TypeContainer.MethodModifiersValid): Move all the
+	method modifier validation to the typecontainer so we can reuse
+	this on properties.
+
+	(MethodCore.ParameterTypes): return an empty sized array of types.
+
+	(Property.Define): Test property modifier validity.
+
+	Add tests for sealed/override too.
+
+	(Method.Emit): abstract or extern methods have no bodies.
+
+2001-12-14  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (Method.IsPInvoke): Get rid of it as it is an expensive
+	thing.
+
+	(Method::Define, ::Emit): Modify accordingly.
+
+	* expression.cs (Invocation::OverloadResolve): Handle error # 121.
+
+	(ArrayCreation::MakeByteBlob): Handle floats and doubles.
+
+	* makefile: Pass in /unsafe.
+
+2001-12-13  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (MakeKey): Kill routine.
+	
+	* class.cs (TypeContainer.Define): Correctly define explicit
+	method implementations (they require the full interface name plus
+	the method name).
+
+	* typemanager.cs: Deply the PtrHashtable here and stop using the
+	lame keys.  Things work so much better.
+
+	This of course broke everyone who depended on `RegisterMethod' to
+	do the `test for existance' test.  This has to be done elsewhere.
+
+	* support.cs (PtrHashtable): A hashtable that avoid comparing with
+	the object stupid Equals method (because, that like fails all over
+	the place).  We still do not use it.
+
+	* class.cs (TypeContainer.SetRequiredInterface,
+	TypeContainer.RequireMethods): Killed these two routines and moved
+	all the functionality to RegisterRequiredImplementations.
+
+	(TypeContainer.RegisterRequiredImplementations): This routine now
+	registers all the implementations required in an array for the
+	interfaces and abstract methods.  We use an array of structures
+	which can be computed ahead of time to reduce memory usage and we
+	also assume that lookups are cheap as most classes will not
+	implement too many interfaces.
+
+	We also avoid creating too many MethodSignatures.
+
+	(TypeContainer.IsInterfaceMethod): Update and optionally does not
+	clear the "pending" bit if we find that there are problems with
+	the declaration.
+
+	(TypeContainer.VerifyPendingMethods): Update to report errors of
+	methods that look like implementations but are not.
+
+	(TypeContainer.Define): Add support for explicit interface method
+	implementation. 
+	
+2001-12-12  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs: Keep track of the parameters here instead of
+	being a feature of the TypeContainer.
+
+	* class.cs: Drop the registration of parameters here, as
+	InterfaceMethods are also interface declarations.
+
+	* delegate.cs: Register methods with the TypeManager not only with
+	the TypeContainer.  This code was buggy.
+
+	* interface.cs: Full registation here.
+
+2001-12-11  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs: Remove reducer for binary expressions, it can not
+	be done this way.
+
+	* const.cs: Put here the code that used to go into constant.cs
+
+	* constant.cs: Put here the code for constants, this is a new base
+	class for Literals.
+
+	* literal.cs: Make Literal derive from Constant.
+
+2001-12-09  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (Return.Emit): Report error 157 if the user
+	attempts to return from a finally block.
+
+	(Return.Emit): Instead of emitting a return, jump to the end of
+	the function.
+
+	* codegen.cs (EmitContext): ReturnValue, ReturnLabel: new
+	LocalBuilder to store the result of the function.  ReturnLabel is
+	the target where we jump.
+	
+
+2001-12-09  Radek Doulik  <rodo@ximian.com>
+
+	* cs-parser.jay: remember alias in current namespace

+
+	* namespace.cs (UsingAlias): add alias, namespace_or_type pair to
+	aliases hashtable
+	(LookupAlias): lookup alias in this and if needed in parent
+	namespaces

+2001-12-08  Miguel de Icaza  <miguel@ximian.com>
+
+	* support.cs: 
+
+	* rootcontext.cs: (ModuleBuilder) Made static, first step into
+	making things static.  I need this to avoid passing the
+	TypeContainer when calling ParameterType.
+
+	* support.cs (InternalParameters.ParameterType): Remove ugly hack
+	that did string manipulation to compute the type and then call
+	GetType.  Use Parameter.ParameterType instead.
+
+	* cs-tokenizer.cs: Consume the suffix for floating values.
+
+	* expression.cs (ParameterReference): figure out whether this is a
+	reference parameter or not.  Kill an extra variable by computing
+	the arg_idx during emission.
+
+	* parameter.cs (Parameters.GetParameterInfo): New overloaded
+	function that returns whether a parameter is an out/ref value or not.
+
+	(Parameter.ParameterType): The type of the parameter (base,
+	without ref/out applied).
+	
+	(Parameter.Resolve): Perform resolution here.
+	(Parameter.ExternalType): The full type (with ref/out applied).
+
+	* statement.cs (Using.Emit, Using.EmitExpression): Implement
+	support for expressions on the using statement.
+
+2001-12-07  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (Using.EmitLocalVariableDecls): Split the
+	localvariable handling of the using statement.
+
+	(Block.EmitMeta): Keep track of variable count across blocks.  We
+	were reusing slots on separate branches of blocks.
+
+	(Try.Emit): Emit the general code block, we were not emitting it. 
+
+	Check the type of the declaration to be an IDisposable or
+	something that can be implicity converted to it. 
+
+	Emit conversions if required.
+
+	* ecore.cs (EmptyExpression): New utility class.
+	(Expression.ImplicitConversionExists): New utility function.
+
+2001-12-06  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (Using): Implement.

+	* ecore.cs (ConvCast): new class used to encapsulate the various
+	explicit integer conversions that works in both checked and
+	unchecked contexts.
+
+	(Expression.ConvertNumericExplicit): Use new ConvCast class to
+	properly generate the overflow opcodes.
+
+2001-12-04  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs: The correct type for the EmptyExpression is the
+	element_type, not the variable type.  Ravi pointed this out.
+
+2001-12-04  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (Method::Define): Handle PInvoke methods specially
+	by using DefinePInvokeMethod instead of the usual one.
+
+	* attribute.cs (DefinePInvokeMethod): Implement as this is what is called
+	above to do the task of extracting information and defining the method.
+	
+2001-12-04  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (ArrayCreation::EmitStaticInitializers): Get rid
+	of the condition for string type.
+
+	(Emit): Move that here. 
+
+	(ArrayCreation::CheckIndices): Keep string literals in their expression
+	form.
+
+	(EmitDynamicInitializers): Handle strings appropriately.
+
+2001-12-04  Miguel de Icaza  <miguel@ximian.com>
+

+	EmitContext.
+
+2001-12-03  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs 
+
+	* statement.cs (GotoDefault), cs-parser.jay: Implement `goto
+	default'.
+	
+	(Foreach.Emit): Foreach on arrays was not setting

+	(MemberAccess.DoResolve): Split this routine into a
+	ResolveMemberAccess routine that can be used independently
+
+2001-11-28  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (Probe, Is, As): Split Probe in two classes Is and
+	As that share bits of the implementation.  Is returns a boolean,
+	while As returns the Type that is being probed.
+
+2001-12-01  Ravi Pratap  <ravi@ximian.com>
+
+	* enum.cs (LookupEnumValue): Re-write various bits, return an object value
+	instead of a Literal - much easier.
+
+	(EnumInTransit): Remove - utterly useless :-)
+
+	(Populate): Re-write bits - remove duplicate code etc. The code is much neater now.
+
+	* expression.cs (MemberLookup): Cope with user-defined enums when they are in transit.
+
+	* enum.cs (LookupEnumValue): Auto-compute next values by going down the dependency
+	chain when we have no associated expression.
+
+2001-11-30  Ravi Pratap  <ravi@ximian.com>

+
+	* ecore.cs (Expression.ConvertIntLiteral): New function to convert

+
+2001-11-24  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (ArrayCreation): Get rid of ArrayExprs : we save
+	some memory.
+
+	(EmitDynamicInitializers): Cope with the above since we extract data
+	directly from ArrayData now.
+
+	(ExpectInitializers): Keep track of whether initializers are mandatory
+	or not.
+
+	(Bounds): Make it a hashtable to prevent the same dimension being 
+	recorded for every element in that dimension.
+
+	(EmitDynamicInitializers): Fix bug which prevented the Set array method
+	from being found.
+
+	Also fix bug which was causing the indices to be emitted in the reverse
+	order.
+
+2001-11-24  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (ArrayCreation): Implement the bits that Ravi left

+	sloppy.
+
+2001-11-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay: Remove bogus fixme.
+

+
+2001-11-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* statement.cs (If.Emit): Fix a bug that generated incorrect code
+	on If.  Basically, we have to return `true' (ie, we do return to

+
+	* expression.cs (Binary.Emit): LogicalOr and LogicalAnd are
+	short-circuit operators, handle them as short circuit operators. 
+
+	(Cast.DoResolve): Resolve type.
+	(Cast.Cast): Take an expression as the target type.
+
+	* cs-parser.jay (cast_expression): Remove old hack that only
+	allowed a limited set of types to be handled.  Now we take a
+	unary_expression and we resolve to a type during semantic
+	analysis.
+
+	Use the grammar productions from Rhys to handle casts (this is
+	not complete like Rhys syntax yet, we fail to handle that corner
+	case that C# has regarding (-x), but we will get there.
+	
+2001-11-22  Ravi Pratap  <ravi@ximian.com>
+
+	* class.cs (EmitFieldInitializer): Take care of the case when we have a
+	field which is an array type.
+
+	* cs-parser.jay (declare_local_variables): Support array initialization too.
+
+	* typemanager.cs (MakeKey): Implement.
+
+	(everywhere): Use the above appropriately.
+
+	* cs-parser.jay (for_statement): Update for array initialization while

+
+	(MemberAccess::DoResolve): Fix the code which handles Enum literals to set
+	the correct type etc.
+
+	(ConvertExplicit): Handle Enum types by examining the underlying type.
+
+2001-11-21  Ravi Pratap  <ravi@ximian.com>

+	* statement.cs (Foreach.ProbeCollectionType): Need to pass
+	BindingFlags.Instance as well 
+
+	* ecore.cs (Expression.TryImplicitIntConversion): Wrap the result
+	implicit int literal conversion in an empty cast so that we

+	by unboxing.
+
+	(Expression.ImplicitNumericConversion): Oops, forgot to test for

+	literal cast.
+
+2001-11-21  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay (for_statement): Reworked the way For works: now
+	we declare manually any variables that are introduced in
+	for_initializer to solve the problem of having out-of-band code
+	emition (that is what got for broken).
+
+	(declaration_statement): Perform the actual variable declaration
+	that used to be done in local_variable_declaration here.
+
+	(local_variable_declaration): Do not declare anything, just pass
+	the information on a DictionaryEntry
+
+2001-11-20  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (ArrayCreation::CheckIndices): The story continues :-) Complete

+	(UpdateIndices): Re-write accordingly.
+
+	Store element data in a separate ArrayData list in the above methods.
+
+	(MakeByteBlob): Implement to dump the array data into a byte array.

+	we can use this elsewhere.
+
+	* statement.cs: Finish implementation of foreach for single
+	dimension arrays.
+
+	* cs-parser.jay: Use an out-of-band stack to pass information
+	around, I wonder why I need this.
+
+	foreach_block: Make the new foreach_block the current_block.
+
+	* parameter.cs (Parameters.GetEmptyReadOnlyParameters): New
+	function used to return a static Parameters structure.  Used for
+	empty parameters, as those are created very frequently.
+
+	* cs-parser.jay, class.cs: Use GetEmptyReadOnlyParameters
+
+2001-11-15  Ravi Pratap  <ravi@ximian.com>
+
+	* interface.cs : Default modifier is private, not public. The

+
+2001-11-15  Ravi Pratap  <ravi@ximian.com>
+
+	* support.cs (ReflectionParameters): Fix logic to determine
+	whether the last parameter is a params one. Test 9 passes again.

+
+	(indexer_declaration): Similar stuff.
+
+	(attribute): Ditto.
+
+	* class.cs (Property): Register parameters for the Get and Set methods
+	if they exist. Test 23 passes again.
+

+	call to EmitArguments as we are sure there aren't any params arguments. 
+	Test 32 passes again.
+
+	* suppor.cs (ParameterDesc, ParameterModifier): Fix trivial bug causing

+	
+2001-11-15  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-parser.jay: Kill horrendous hack ($??? = lexer.Location) that

+
+2001-11-09  Miguel de Icaza  <miguel@ximian.com>
+
+	* enum.cs (Enum.Emit): Delay the lookup of loc until we run into

+
+	* class.cs (Method.Emit): Clean up.
+
+	* expression.cs (Argument.Resolve): Take another argument: the
+	location where this argument is used.  Notice that this is not

+
+	Test if the argument is a variable-reference, if not, then
+	complain with a 206.
+
+	(Argument.Emit): Emit addresses of variables.
+
+	(Argument.FullDesc): Simplify.
+
+	(Invocation.DoResolve): Update for Argument.Resolve.

+	IAssignMethod instead. 
+
+2001-11-13  Miguel de Icaza <miguel@ximian.com>
+
+	* parameter.cs, expression.cs, class.cs, ecore.cs: Made all
+	enumerations that are used in heavily used structures derive from
+	byte in a laughable and pathetic attempt to reduce memory usage.
+	This is the kind of pre-optimzations that you should not do at
+	home without adult supervision.
+
+	* expression.cs (UnaryMutator): New class, used to handle ++ and
+	-- separatedly from the other unary operators.  Cleans up the
+	code, and kills the ExpressionStatement dependency in Unary.
+
+	(Unary): Removed `method' and `Arguments' from this class, making
+	it smaller, and moving it all to SimpleCall, so I can reuse this
+	code in other locations and avoid creating a lot of transient data
+	strucutres when not required.
+
+	* cs-parser.jay: Adjust for new changes.
+
+2001-11-11  Miguel de Icaza  <miguel@ximian.com>
+
+	* enum.cs (Enum.Populate): If there is a failure during
+	definition, return
+
+	* cs-parser.jay (opt_enum_base): we used to catch type errors

+
+	* statement.cs (For.Emit): Cope with null initializers.

+	IStackStore as the order in which arguments are passed reflects
+	this.
+
+	* assign.cs: Instead of using expr.ExprClass to select the way of
+	assinging, probe for the IStackStore/IAssignMethod interfaces.
+
+	* typemanager.cs: Load InitializeArray definition.

+2001-11-04  Ravi Pratap  <ravi@ximian.com>

+	* cs-parser.jay: Make foreach a toplevel object instead of the

+
+	* expression.cs (Cast): Record location info.
+
+	(Expression::ConvertExplicit): Take location argument.
+
+	(UserImplicitCast): Change name to UserCast. Take an extra constructor argument
+	to determine if we are doing explicit conversions.
+
+	(UserCast::Emit): Update accordingly.
+
+	(Expression::ConvertExplicit): Report an error if everything fails.
+
+	* ../errors/cs0030.cs : Add.
+
+2001-10-04  Miguel de Icaza  <miguel@ximian.com>
+
+	* modifiers.cs: If the ABSTRACT keyword is present, also set the
+	virtual and newslot bits. 
+
+	* class.cs (TypeContainer::RegisterRequiredImplementations):
+	Record methods we need.
+
+	(TypeContainer::MakeKey): Helper function to make keys for
+	MethodBases, since the Methodbase key is useless.
+
+	(TypeContainer::Populate): Call RegisterRequiredImplementations
+	before defining the methods.   
+
+	Create a mapping for method_builders_to_methods ahead of time
+	instead of inside a tight loop.
+
+	(::RequireMethods):  Accept an object as the data to set into the
+	hashtable so we can report interface vs abstract method mismatch.
+
+2001-10-03  Miguel de Icaza  <miguel@ximian.com>
+
+	* report.cs: Make all of it static.
+
+	* rootcontext.cs: Drop object_type and value_type computations, as
+	we have those in the TypeManager anyways.
+
+	Drop report instance variable too, now it is a global.
+

+
+	Add --probe option to debug the error reporting system with a test

+
+2001-10-03  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (Binary::DoNumericPromotions): Fix the case when
+	we do a forcible conversion regardless of type, to check if 
+	ForceConversion returns a null.
+
+	(Binary::error19): Use location to report error.
+
+	(Unary::error23): Use location here too.
+
+	* ../errors/cs0019.cs : Check in.
+
+	* ../errors/cs0023.cs : Check in.
+
+	* expression.cs (Expression.MemberLookup): Return null for a rather esoteric
+	case of a non-null MethodInfo object with a length of 0 !
+
+	(Binary::ResolveOperator): Flag error if overload resolution fails to find
+	an applicable member - according to the spec :-)
+	Also fix logic to find members in base types.
+
+	(Unary::ResolveOperator): Same here.
+
+	(Unary::report23): Change name to error23 and make first argument a TypeContainer
+	as I was getting thoroughly confused between this and error19 :-)

+	(::FindMostEncompassedType): Implement.
+	(::FindMostEncompassingType): Implement.
+	(::StandardConversionExists): Implement.
+

+
+	(Invocation::MakeUnionSet): Completely re-write to make sure we form a proper
+	mathematical union with no duplicates.
+
+2001-10-03  Miguel de Icaza  <miguel@ximian.com>
+
+	* rootcontext.cs (RootContext::PopulateTypes): Populate containers
+	in order from base classes to child classes, so that we can in
+	child classes look up in our parent for method names and
+	attributes (required for handling abstract, virtual, new, override
+	constructs: we need to instrospect our base class, and if we dont
+	populate the classes in order, the introspection might be
+	incorrect.  For example, a method could query its parent before
+	the parent has any methods and would determine that the parent has
+	no abstract methods (while it could have had them)).
+
+	(RootContext::CreateType): Record the order in which we define the
+	classes.
+
+2001-10-02  Miguel de Icaza  <miguel@ximian.com>
+
+	* class.cs (TypeContainer::Populate): Also method definitions can

+
+2001-10-02  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (Unary::ResolveOperator): Find operators on base type

+	* ../errors/cs0555.cs : Added.
+
+2001-10-01  Miguel de Icaza  <miguel@ximian.com>
+
+	* cs-tokenizer.cs: Reimplemented Location to be a struct with a
+	single integer which is really efficient
+
+2001-10-01  Ravi Pratap  <ravi@ximian.com>
+
+	*  expression.cs (Expression::ImplicitUserConversion): Use location
+        even in the case when we are examining True operators.
+ 
+        * class.cs (Operator::Define): Perform extensive checks to conform
+        with the rules for operator overloading in the spec.
+
+	* expression.cs (Expression::ImplicitReferenceConversion): Implement
+	some of the other conversions mentioned in the spec.
+
+	* typemanager.cs (array_type): New static member for the System.Array built-in
+	type.
+
+	(cloneable_interface): For System.ICloneable interface.
+
+	* driver.cs (Driver::Driver): Initialize TypeManager's core types even before
+	we start resolving the tree and populating types.
+
+	* ../errors/errors.txt : Update for error numbers -7, -8, -9, -10
+ 
+2001-10-01  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (Expression::ExprClassFromMemberInfo,
+	Expression::Literalize): Create literal expressions from
+	FieldInfos which are literals.
+
+	(ConvertNumericExplicit, ImplicitNumericConversion): Fix a few
+	type casts, because they were wrong.  The test suite in tests
+	caught these ones.
+
+	(ImplicitNumericConversion): ushort to ulong requires a widening
+	cast. 
+
+	Int32 constant to long requires widening cast as well.
+
+	* literal.cs (LongLiteral::EmitLong): Do not generate i4 constants
+	for integers because the type on the stack is not i4.
+
+2001-09-30  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (report118): require location argument. 
+
+	* parameter.cs: Do not dereference potential null value.
+
+	* class.cs: Catch methods that lack the `new' keyword when
+	overriding a name.  Report warnings when `new' is used without
+	anything being there to override.
+
+	* modifiers.cs: Handle `NEW' as MethodAttributes.NewSlot.
+
+	* class.cs: Only add constructor to hashtable if it is non-null
+	(as now constructors can fail on define).
+
+	(TypeManager, Class, Struct): Take location arguments.
+
+	Catch field instance initialization in structs as errors.
+
+	accepting_filter: a new filter for FindMembers that is static so
+	that we dont create an instance per invocation.
+
+	(Constructor::Define): Catch errors where a struct constructor is
+	parameterless 
+
+	* cs-parser.jay: Pass location information for various new
+	constructs. 
+	
+	* delegate.cs (Delegate): take a location argument.
+
+	* driver.cs: Do not call EmitCode if there were problesm in the
+	Definition of the types, as many Builders wont be there. 
+
+	* decl.cs (Decl::Decl): Require a location argument.
+
+	* cs-tokenizer.cs: Handle properly hex constants that can not fit
+	into integers, and find the most appropiate integer for it.
+
+	* literal.cs: Implement ULongLiteral.
+
+	* rootcontext.cs: Provide better information about the location of
+	failure when CreateType fails.
+	
+2001-09-29  Miguel de Icaza  <miguel@ximian.com>
+
+	* rootcontext.cs (RootContext::PopulateTypes): Populates structs
+	as well.
+
+	* expression.cs (Binary::CheckShiftArguments): Add missing type
+	computation.
+	(Binary::ResolveOperator): Add type to the logical and and logical
+	or, Bitwise And/Or and Exclusive Or code paths, it was missing
+	before.
+
+	(Binary::DoNumericPromotions): In the case where either argument
+	is ulong (and most signed types combined with ulong cause an
+	error) perform implicit integer constant conversions as well.
+
+2001-09-28  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (UserImplicitCast): Method should always be
+	non-null. 
+	(Invocation::BetterConversion): Simplified test for IntLiteral.
+
+	(Expression::ImplicitNumericConversion): Split this routine out.
+	Put the code that performs implicit constant integer conversions
+	here. 
+
+	(Expression::Resolve): Become a wrapper around DoResolve so we can
+	check eclass and type being set after resolve.
+
+	(Invocation::Badness): Remove this dead function
+
+	(Binary::ResolveOperator): Do not compute the expensive argumnets
+	unless we have a union for it.
+
+	(Probe::Emit): Is needs to do an isinst and then
+	compare against null.
+
+	(::CanConvert): Added Location argument.  If the Location argument
+	is null (Location.Null), then we do not report errors.  This is
+	used by the `probe' mechanism of the Explicit conversion.  We do
+	not want to generate an error for something that the user
+	explicitly requested to be casted.  But the pipeline for an
+	explicit cast first tests for potential implicit casts.
+
+	So for now, if the Location is null, it means `Probe only' to
+	avoid adding another argument.   Might have to revise this
+	strategy later.
+
+	(ClassCast): New class used to type cast objects into arbitrary
+	classes (used in Explicit Reference Conversions).
+
+	Implement `as' as well.
+
+	Reverted all the patches from Ravi below: they were broken:
+
+		* The use of `level' as a mechanism to stop recursive
+		  invocations is wrong.  That was there just to catch the
+		  bug with a strack trace but not as a way of addressing
+		  the problem.
+
+		  To fix the problem we have to *understand* what is going
+		  on and the interactions and come up with a plan, not
+		  just get things going.
+
+		* The use of the type conversion cache that I proposed
+		  last night had an open topic: How does this work across
+		  protection domains.  A user defined conversion might not
+		  be public in the location where we are applying the
+		  conversion, a different conversion might be selected
+		  (ie, private A->B (better) but public B->A (worse),
+		  inside A, A->B applies, but outside it, B->A will
+		  apply).
+
+		* On top of that (ie, even if the above is solved),
+		  conversions in a cache need to be abstract.  Ie, `To
+		  convert from an Int to a Short use an OpcodeCast', not
+		  `To convert from an Int to a Short use the OpcodeCast on
+		  the variable 5' (which is what this patch was doing).
+	
+2001-09-28  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (Invocation::ConversionExists): Re-write to use
+	the conversion cache
+	
+	(Expression::ConvertImplicit): Automatic bailing out if level != 0. Also
+	cache all conversions done, not just user-defined ones.
+
+	(Invocation::BetterConversion): The real culprit. Use ConversionExists
+	to determine if a conversion exists instead of acutually trying to 
+	perform the conversion. It's faster too.
+
+	(Expression::ConvertExplicit): Modify to use ConversionExists to check
+	and only then attempt the implicit conversion.
+
+2001-09-28  Ravi Pratap  <ravi@ximian.com>
+
+	* expression.cs (ConvertImplicit): Use a cache for conversions
+	already found. Check level of recursion and bail out if necessary.
+	
+2001-09-28  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs (string_concat_string_string, string_concat_object_object):

+	
+	* statement.cs (Block::UsageWarning): Track usage of variables and
+	report the errors for not used variables.
+
+	* expression.cs (Conditional::Resolve, ::Emit): Implement ?:
+	operator. 
+
+2001-09-27  Miguel de Icaza  <miguel@ximian.com>
+
+	* codegen.cs: remove unnneded code 
+
+	* expression.cs: Removed BuiltinTypeAccess class
+
+	Fix the order in which implicit conversions are
+	done.  
+
+	The previous fixed dropped support for boxed conversions (adding a
+	test to the test suite now)
+
+	(UserImplicitCast::CanConvert): Remove test for source being null,
+	that code is broken.  We should not feed a null to begin with, if
+	we do, then we should track the bug where the problem originates
+	and not try to cover it up here.
+
+	Return a resolved expression of type UserImplicitCast on success
+	rather than true/false.  Ravi: this is what I was talking about,
+	the pattern is to use a static method as a "constructor" for
+	objects. 
+
+	Also, do not create arguments until the very last minute,
+	otherwise we always create the arguments even for lookups that
+	will never be performed. 
+
+	(UserImplicitCast::Resolve): Eliminate, objects of type
+	UserImplicitCast are born in a fully resolved state. 
+	
+	* typemanager.cs (InitCoreTypes): Init also value_type
+	(System.ValueType). 
+
+	* expression.cs (Cast::Resolve): First resolve the child expression.
+
+	(LValue): Add new method AddressOf to be used by
+	the `&' operator.  
+
+	Change the argument of Store to take an EmitContext instead of an
+	ILGenerator, because things like FieldExpr need to be able to call
+	their children expression to generate the instance code. 
+
+	(Expression::Error, Expression::Warning): Sugar functions for
+	reporting errors.
+
+	(Expression::MemberLookup): Accept a TypeContainer instead of a
+	Report as the first argument.
+
+	(Expression::ResolvePrimary): Killed.  I still want to improve
+	this as currently the code is just not right.
+
+	(Expression::ResolveMemberAccess): Simplify, but it is still
+	wrong. 
+
+	(Unary::Resolve): Catch errors in AddressOf operators.
+
+	(LocalVariableReference::Emit, ::Store, ::AddressOf): typecast
+	index to a byte for the short-version, or the compiler will choose
+	the wrong Emit call, which generates the wrong data.
+
+	(ParameterReference::Emit, ::Store): same.
+
+	(FieldExpr::AddressOf): Implement.
+	
+	* typemanager.cs: TypeManager: made public variable instead of
+	property.
+	
+	* driver.cs: document --fatal.
+
+	* report.cs (ErrorMessage, WarningMessage): new names for the old
+	Error and Warning classes.
+
+	* cs-parser.jay (member_access): Turn built-in access to types
+	into a normal simplename

+	* expression.cs (UserImplicitCast::CanConvert): Static method to do 
+	the work of all the checking. 
+	(ConvertImplicit): Call CanConvert and only then create object if necessary.
+	(UserImplicitCast::CanConvert, ::Resolve): Re-write.
+
+	(Unary::Operator): Rename Add and Subtract to Addition and Subtraction because
+	that is the right way. 
+
+	(Invocation::MakeUnionSet): Convenience function to make unions of sets for 
+	overloading resolution. Use everywhere instead of cutting and pasting code.
+
+	(Binary::ResolveOperator): Use MakeUnionSet.
+
+	(UserImplicitCast::CanConvert, ::Resolve): Update to take care of the case when 
+	we have to convert to bool types. Not complete yet.

+

+2001-09-26  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (Unary::Emit): Remove some dead code.
+	(Probe): Implement Resolve and Emit for `is'.
+	(Expression::ConvertImplicitRequired): Attempt to do constant
+	expression conversions here.  Maybe should be moved to
+	ConvertImplicit, but I am not sure.
+	(Expression::ImplicitLongConstantConversionPossible,
+	Expression::ImplicitIntConstantConversionPossible): New functions
+	that tell whether is it possible to apply an implicit constant

+	(Parameters::VerifyArgs): Verifies that no two arguments have the
+	same name. 
+
+	* class.cs (Operator): Update the operator names to reflect the
+	ones that the spec expects (as we are just stringizing the
+	operator names).
+	
+	* expression.cs (Unary::ResolveOperator): Fix bug: Use
+	MethodInfo's ReturnType instead of LookupMethodByBuilder as the
+	previous usage did only work for our methods.
+	(Expression::ConvertImplicit): Handle decimal implicit numeric
+	conversions as well.
+	(Expression::InternalTypeConstructor): Used to invoke constructors
+	on internal types for default promotions.
+
+	(Unary::Emit): Implement special handling for the pre/post
+	increment/decrement for overloaded operators, as they need to have
+	the same semantics as the other operators.
+
+	(Binary::ResolveOperator): ditto.
+	(Invocation::ConversionExists): ditto.

+	
+2001-09-26  Ravi Pratap  <ravi@ximian.com>

+
+	* expression.cs (ExpressionStatement): New base class used for
+	expressions that can appear in statements, so that we can provide
+	an alternate path to generate expression that do not leave a value
+	on the stack.
+
+	(Expression::Emit, and all the derivatives): We no longer return
+	whether a value is left on the stack or not.  Every expression

+
+	* codegen.cs (EmitContext::EmitStatementExpression): Use the
+	facilties of ExpressionStatement if possible.

+	Okay, things work fine !
+
+2001-09-21  Miguel de Icaza  <miguel@ximian.com>
+
+	* typemanager.cs: declare and load enum_type, delegate_type and
+	void_type. 
+
+	* expression.cs (Expression::Emit): Now emit returns a value that
+	tells whether a value is left on the stack or not.  This strategy
+	might be reveted tomorrow with a mechanism that would address

+
+2001-09-14  Ravi Pratap  <ravi@ximian.com>

+2001-09-13  Miguel de Icaza  <miguel@ximian.com>
+
+	* expression.cs (MemberLookup): Fruitless attempt to lookup

+	comparission operators
+
+	* typemanager.cs: Remove debugging print code.
+
+	(Invocation::Resolve): resolve type.
+

+	(Method::) Keep track of parameters, due to System.Reflection holes
+
+	(TypeContainer::Populate): Keep track of MethodBuilders to Method
+	mapping here.
+
+	(TypeContainer::FindMembers): Use ArrayList and then copy an array
+	of the exact size and return that.
+
+	(Class::LookupMethodByBuilder): New function that maps
+	MethodBuilders to its methods.  Required to locate the information
+	on methods because System.Reflection bit us again.
+
+	* support.cs: New file, contains an interface ParameterData and
+	two implementations: ReflectionParameters and InternalParameters
+	used to access Parameter information.  We will need to grow this
+	as required.

+
+	* genericparser.cs (GenericParser::error): Overloaded method to handle the case

+	on Expression Classification.  Now all expressions have a method
+	`Resolve' and a method `Emit'.

+	code. 
+	
+2001-08-24  Miguel de Icaza  <miguel@ximian.com>
+
+	* codegen.cs: Lots of code generation pieces.  This is only the

+	or a structure to apply the `has-this' bit.

+	instead arrays of Parameters.

+	* driver.cs: Make sure we always load mscorlib first (for
+	debugging purposes, nothing really important).
+
+	* Renamespaced things that were on `CSC' to `CIR'.  Maybe I should
+	have moved to `CSC' rather than `CIR'.  Oh man!  The confussion!

+	on namespaces that have been imported using the `using' keyword.

+
+	* tree.cs: Removed RecordType, added RecordClass, RecordStruct and
+	RecordInterface instead.
+
+	* cs-parser.jay: Updated to reflect changes above.

+	I have not figured out why the Microsoft version puts an
+	`instance' attribute, and I am not generating this `instance' attribute.
+
+	Explanation: The reason for the `instance' attribute on
+	indexers is that indexers only apply to instances
+
+* Indexer bugs:
+
+	the following wont work:
+
+	x [0] = x [1] = N
+
+	if x has indexers, the value of x [N] set is set to void.  This needs to be
+	fixed.
+
+* Array declarations
+
+	Multi-dim arrays are declared as [,] instead of [0..,0..]
+
+* Break/Continue statements
+
+	A finally block should reset the InLoop/LoopBegin/LoopEnd, as
+	they are logically outside the scope of the loop.
+
+* Break/continue part 2.
+
+	They should transfer control to the finally block if inside a try/catch
+	block.
+
+* Method Registration and error CS111
+
+	The way we use the method registration to signal 111 is wrong.
+	
+	Method registration should only be used to register methodbuilders,
+	we need an alternate method of checking for duplicates.
+
+* We need to catch:
+
+	extern string Property {
+		get { } 
+	}
+
+	The get there should only have a semicolon
+	
+*
+> // CSC sets beforefieldinit
+> class X {
+>   // .cctor will be generated by compiler
+>   public static readonly object O = new System.Object ();
+>   public static void Main () {}
+> }
+> 
+
+PENDING TASKS
+-------------
+
+* IMprove error handling here:
+
+	public static Process ()
+
+	THat assumes that it is a constructor, check if its the same name
+	as the class, if not report a different error than the one we use now.
+
+* Merge test 89 and test-34
+
+* Revisit
+
+	Primary-expression, as it has now been split into 
+	non-array-creation-expression and array-creation-expression.
+		
+* Static flow analysis
+
+	Required to warn about reachability of code and definite
+	assignemt as well as missing returns on functions.
+
+* Code cleanup
+
+	The information when registering a method in InternalParameters
+	is duplicated, you can always get the types from the InternalParameters
+
+* Emit modreq for volatiles
+
+	Handle modreq from public apis.
+
+* Emit `pinned' for pinned local variables.
+
+	Both `modreq' and pinned will require special hacks in the compiler.
+
+* Make sure that we are pinning the right variable
+
+* Maybe track event usage?  Currently I am not tracking these, although they
+  are fields.
+
+* Merge tree.cs, rootcontext.cs
+
+OPTIMIZATIONS
+-------------
+
+* Implement loop inversion for `For' as well.
+
+* There is too much unshared code between MemberAccess.Resolve and SimpleName
+  resolve.  
+ 
+* User Defined Conversions is doing way too many calls to do union sets that are not needed
+
+* Add test case for destructors
+
+* Places that use `Ldelema' are basically places where I will be
+  initializing a value type.  I could apply an optimization to 
+  disable the implicit local temporary from being created (by using
+  the method in New).
+
+* Dropping TypeContainer as an argument to EmitContext
+
+ 	My theory is that I can get rid of the TypeBuilder completely from
+	the EmitContext, and have typecasts where it is used (from
+	DeclSpace to where it matters).  
+
+	The only pending problem is that the code that implements Aliases
+	is on TypeContainer, and probably should go in DeclSpace.
+
+* Casts need to trigger a name resolution against types only.
+
+	currently we use a secret hand shake, probably we should use
+	a differen path, and only expressions (memberaccess, simplename)
+	would participate in this protocol.
+
+* Use of local temporary in UnaryMutator
+
+	We should get rid of the Localtemporary there for some cases
+
+* Emitcontext
+
+	Do we really need to instanciate this variable all the time?
+
+	It could be static for all we care, and just use it for making
+	sure that there are no recursive invocations on it.
+
+* Use of EmitBranchable
+
+	Currently I use brfalse/brtrue in the code for statements, instead of
+	using the EmitBranchable function that lives in Binary
+
+* ConvertImplicit
+
+	Currently ConvertImplicit will not catch things like:
+
+	- IntLiteral in a float context to generate a -FloatLiteral.
+	Instead it will perform an integer load followed by a conversion.
+
+* Tests
+
+	Write tests for the various reference conversions.  We have
+	test for all the numeric conversions.
+
+* Optimizations
+
+	In Indexers and Properties, probably support an EmitWithDup
+	That emits the code to call Get and then leaves a this pointer
+	in the stack, so that later a Store can be emitted using that
+	this pointer (consider Property++ or Indexer++)
+
+* Optimizations: variable allocation.
+
+	When local variables of a type are required, we should request
+	the variable and later release it when we are done, so that
+	the same local variable slot can be reused later on.
+
+* Add a cache for the various GetArrayMethod operations.
+
+* TypeManager.FindMembers:
+
+	Instead of having hundreds of builder_to_blah hash table, have
+	a single one that maps a TypeBuilder `t' to a set of classes
+	that implement an interface that supports FindMembers.
+
+* MakeUnionSet Callers
+
+	If the types are the same, there is no need to compute the unionset,
+ 	we can just use the list from one of the types.
+
+* Factor all the FindMembers in all the FindMembers providers.
+
+* Factor the lookup code for class declarations an interfaces
+  (interface.cs:GetInterfaceByName)
+
+RECOMMENDATIONS
+---------------
+
+* Use of lexer.Location in the parser
+
+	Currently we do:
+
+	TOKEN nt TERMINAL nt TERMINAL nt3 {
+		$$ = new Blah ($2, $4, $6, lexer.Location);
+	}
+
+	This is bad, because the lexer.Location is for the last item in `nt3'
+
+	We need to change that to use this pattern:
+
+	TOKEN { oob_stack.Push (lexer.Location) } nt TERMINAL nt TERMINAL nt3 {
+		$$ = new Blah ($3, $5, $7, (Location) oob_stack.Pop ());
+	}
+
+	Notice how numbering of the arguments changes as the
+	{ oob_stack.Push (lexer.Location) } takes a "slot"  in the productions.
+
+* local_variable_declaration
+
+	Not sure that this grammar is correct, we might have to
+	resolve this during semantic analysis.
+
+* Idea
+
+	MethodGroupExpr
+
+	These guys should only appear as part of an Invocation, so we
+	probably can afford to have a special callback:
+
+		Expression.ResolveAllowMemberGroups
+
+	This is only called by Invocation (or anyone that consumes 
+	MethodGroupExprs)
+
+	And the regular DoResolve and DoResolveLValue do emit the error
+	654 `Method referenced without argument list'.  
+
+	Otherwise, a resolution will return a MethodGroupExpr which is
+	not guaranteed to have set its `Expression.Type' to a non-null
+	value.

+Compiler operation
+
+The compiler has a number of phases:
+
+* Parsing.
+
+	Initially the compiler parses all the source files and keeps a
+	parsed representation in memory.  Very syntax error checking
+	is performed at this point.
+
+	The compiler stores the information in classes whose names
+	represent the language construct, for example, the "if"
+	construct is stored in an `If' class.  A class is stored in a
+	`Class'.
+
+* The TypeManager
+
+	The TypeManager loads all the assemblies that were referenced
+	by the programmer.  The CLR type system is used as our
+	repository for types defined as well.
+
+	So the same interface that is used to query the types,
+	properties and flags about system types is the same interface
+	that we use for our types.
+
+	As we work our way through the code generation and semantic
+	analysis, new types are entered into the Type system through
+	the use of System.Reflection.Emit.  The TypeManager will
+	lookup types on both the user defined types and on the system
+	defined ones.
+
+	So special care has to be used.  The order in which we
+	proceeed from here is important. 
+
+* Base class resolution and type definition.
+
+	Once the parsing has happened, the compiler resolves the
+	inheritance tree for interfaces.   This is done recursively
+	and we catch recursive interface definitions here.
+
+	After this is done, we continue on with classes.  Classes have
+	can have an optional "parent" inherit from or the implicit
+	System.Object class (for normal builds, builds with /nostdlib
+	will allow you to compile class System.Object with no parent).
+
+	At this point we do some error checking and verify that the
+	inherits/implements section of a class is correct (since we
+	have previously built the interface inheritance).
+
+	By the time we are done, all classes, structs and interfaces
+	have been created using System.Reflection.Emit and registered
+	with the Type Manager.
+
+	This allows us to define fields and resolve argument names for
+	methods, properties, indexers and events. 
+
+* Field generation
+
+	Fields are generated next, we go through all the type
+	containers (classes and structs) and enter the fields into
+	their types.
+
+* Method, Properties, Indexers and events definitions
+
+	Now all the methods, constructors, properties, indexers and
+	events are entered.  They are only `defined' using
+	System.Reflection.Emit.  No code generation will happen until
+	everything has been entered into System.Reflection.Emit.
+
+	This is important because to actually generate code we need to
+	know everything about the environment in which the code is
+	being generated.
+
+* Code Generation
+
+	At this point all the definitions have been entered into the
+	type manager through System.Reflection.Emit.  We can now use
+	System.Reflection to query all the information about the
+	types. 
+
+	Your normal semantic analysis and code generation phase lives
+	here.
+
+* Statements
+
+	Most of the statements are handled in the codegen.cs file.
+
+* Expressions
+
+* Error reporting
+
+	We should try to use the `Report.Error' and `Report.Warning'
+	classes which are part of the RootContext (there is even a
+	property to access it).
+
+	Error reporting should try to use the same codes that the
+	Microsoft compiler uses (if only so we can track which errors
+	we handle and which ones we dont).
+
+	If there is an error which is specific to MSC, use negative
+	numbers, and register the number in mcs/errors/errors.txt
+
+	Try to write a test case for any error that you run into the
+	code of the compiler if there is none already.
+
+	Put your test case in a file called csNNNN.cs in the
+	mcs/errors directory, and have the first two lines be:
+
+	// csNNNN.cs: This is the description.
+	// Line: XXX
+
+	Where `XXX' is the line where the error ocurrs.  We will later
+	use this as a regression test suite for catching errors in the
+	compiler.

-// TODO:

-//   (1) Get rid of the *Collections.cs, that is an idea I took from System.CodeDOM

-//       And come to think of it, it is not that great, it duplicates a lot of code

-//       for something which is not really needed.  We still have piles of typecasts

-//       anwyays (due to the nature of the stack being a collection of Objects).

-//

-//   (2) Figure out why error productions dont work.  `type-declaration' is a

-//       great spot to put an `error' because you can reproduce it with this input:

-//	 "public X { }"

-//

-//   (3) Move Modifier checking from each object into the parser itself, that will

-//       get rid of the global "error" symbol that we use now to report errors. 

-//       We still need to pass a pointer to the tree.ErrorHandler, but that is a 

-//	 separate problem

-// TODO:

-//   (1) Get rid of the *Collections.cs, that is an idea I took from System.CodeDOM

-//       And come to think of it, it is not that great, it duplicates a lot of code

-//       for something which is not really needed.  We still have piles of typecasts

-//       anwyays (due to the nature of the stack being a collection of Objects).

-//

-//   (2) Figure out why error productions dont work.  `type-declaration' is a

-//       great spot to put an `error' because you can reproduce it with this input:

-//	 "public X { }"

-//

-//   (3) Move Modifier checking from each object into the parser itself, that will

-//       get rid of the global "error" symbol that we use now to report errors. 

-//       We still need to pass a pointer to the tree.ErrorHandler, but that is a 

-//	 separate problem

-  Todo:

-

-  Do something with the integer and float suffixes, pass full datatype?

-  Make sure we accept the proper Unicode ranges, per the spec.

-

-  Open issues:

-

-  * Data type handling

-  

-	  Currently I am returning different tokens for the various

-	  kinds of floating point types (float, double, decimal) and I

-	  am only returning a single token for all integer values

-	  (integer, unsigned int, etc) as an experiment as to see

-	  which mechanism is better.

-	

-	  I do not know yet how I will be doing the mapping of "int"

-	  to things like System.Int32 and so on.  I am confused.  MAN

-	  I AM C

-	

-	  Indeed, this might be the core of the problem, I should

-	  *probably* just return a TYPE token and have the value of

-	  the token be stuff like `System.Int32', `System.UInt32',

-	  `System.Double' and so on.  I will see.

-

-  * Error reporting.

-

-          I was returning Token.ERROR on errors and setting an

-          internal error string with the details, but it might make sense

-	  to just use exceptions.

-

-	  Change of mind: I think I want to keep returning errors *UNLESS* the

-	  parser is catching errors from the tokenizer (at that point, there is

-	  not really any reason to use exceptions) so that I can continue the

-	  parsing 

-

-  * IDEA

-

-          I think I have solved the problem.  The idea is to not even *bother*

-	  about handling data types a lot here (except for fitting data into

-	  the proper places), but let the upper layer handle it.

-

-	  Ie, treat LITERAL_CHARACTER, LITERAL_INTEGER, LITERAL_FLOAT, LITERAL_DOUBLE, and

-	  return then as `LITERAL_LITERAL' with maybe subdetail information

-

+ * TODO:

+ *   Make sure we accept the proper Unicode ranges, per the spec.

+ *   Report error 1032

+NAnt

+

+What is it? 

+-----------

+NAnt is a .NET based build tool. In theory it is kind of like make without 

+make's wrinkles. In practice it's a lot like Ant. 

+  

+If you are not familiar with Jakarta Ant you can get more information at the

+Jakarta project web site.

+http://jakarta.apache.org/

+

+

+Why NAnt?

+---------

+Because Ant was too Java specific.

+Because Ant needed the Java runtime.  NAnt only needs the .NET runtime.

+

+

+The Latest Version

+------------------

+Details of the latest version can be found on the NAnt project web site

+http://nant.sourceforge.net/

+

+

+Documentation

+-------------

+Documentation is available in HTML format, in the doc/ directory.

+

+	<p>September 18, 2001 Gerry Shaw -- <a title="Send email to Gerry Shaw" href="mailto:gerry_shaw@yahoo.com">gerry_shaw@yahoo.com</a></p>

+	<p>NAnt is a .NET based build tool. In theory it is kind of like make without make's wrinkles. In practice it's a lot like <a title="Ant home page" href="http://jakarta.apache.org/ant/">Ant</a>. NAnt has only been tested with Beta 2 .NET SDK, build 2914.</p>

+	<p>The idea for NAnt came from <a title="Hazware home page" href="http://www.hazware.com/xbHome.htm"> Hazware's XBuild</a> project. After emailing the author for a beta 2 version of the tool and getting no response I decided to port the code to .NET beta 2. Due to the number of changes from .NET beta 1 to beta 2 the result was a total rewrite.</p>

+	<ul>

+		<li><a title="NAnt files page on SourceForge" href="http://sourceforge.net/project/showfiles.php?group_id=31650"><b>Download latest version</b></a> from SourceForge</li>

+		<li><a title="Software license agreement" href="license.html">License</a></li>

+	</ul>

+

+	<h2>Getting Started</h2>

+	<p>Since the software is still in heavy development you are going to be on your own. You can see NAnt build itself by doing the following:</p>

+	<ol>

+		<li>Download the latest released version.</li>

+		<li>Unzip the distribution into a new folder.</li>

+		<li>Using a command prompt (so you can see the build output) cd into the

+			folder where NAnt was unzipped.</li>

+		<li>Type <code>bin\nant</code> at the command prompt to build NAnt.</li>

+	</ol>

+"test\a??.java" matches all files/dirs which start with an 'a', then two

+more characters and then ".java", in a directory called test.

+"**" matches everything in a directory tree.

+

+"**\test\**\XYZ*" matches all files/dirs that start with "XYZ" and where

+there is a parent directory called test (e.g. "abc\test\def\ghi\XYZ123").

+when omitted.

+

+quiet: If the file does not exist, do not display a diagnostic message or

+modify the exit status to reflect an error (unless Ant has been invoked with

+the -verbose or -debug switches). This means that if a file or directory cannot

+be deleted, then no error is reported. This setting emulates the -f option to

+the Unix "rm" command. ("true"/"false"). Default is "false" meaning things are

+"noisy". Setting this to true, implies setting failonerror to false.

+

+failonerror: This flag (which is only of relevance if 'quiet' is false),

+controls whether an error -such as a failure to delete a file- stops the build

+task, or is merely reported to the screen. The default is "true"

+2002-07-19  Martin Baulig  <martin@gnome.org>
+
+	* makefile.gnu, list.unix: Added makefile.gnu for self-hosting
+	GNU/Linux build.
+
+	* src/NUnitConsole/makefile.gnu, src/NUnitConsole/list.unix: Likewise.
+
+2002-03-08  Nick Drochak  <ndrochak@gol.com>
+
+	* nunit.build: exclude all the obsolete stuff, and prevent csc from
+	linking any ms stuff to the dll and exe we are testing on Linux.
+
+2002-03-07  Nick Drochak  <ndrochak@gol.com>
+
+	* .cvsignore: ignore *.pdb files
+	* nunit.build: Build a version of NUnitCore.dll and NUnitConsole.exe
+	using mono's corlib. Use this to test on Linux under mint and mono.
+
+2002-03-06  Nick Drochak  <ndrochak@gol.com>
+
+	* nunit.build: Exclude obsolete class from build. Probably should
+	remove from cvs.
+
+2002-02-27  Martin Baulig  <martin@gnome.org>
+
+	Imported NUnit 1.11.
+
+	* nunit.build: Added NAnt build file for NUnit. In addition to
+	NUnitConsole.exe and NUnitCore.dll, we also create a small
+	NUnitBase.dll which just contains the source files which are needed
+	to run the tests on Linux.
+
+	* RunTests.cs: This is a simple test runner which is used when we
+	run the tests on Linux. It is linked into UNitBase.dll.
+
+	* makefile: Just call NAnt here.
+
+	* NUnitGUI.exe, NUnitTests.dll: Removed binaries.

+	/// </list>

+	/// Each test runs in its own fixture so there can be no side effects 

+	/// among test runs.

+	/// <example>Here is an example:

+	/// <code>

+	/// public class MathTest: TestCase {

+	///   protected double fValue1;

+	///   protected double fValue2;

+	///

+	///   public MathTest(string name) : base(name) {}

+	///

+	///   protected override void SetUp() {

+	///     fValue1= 2.0;

+	///     fValue2= 3.0;

+	///   }

+	/// }</code>

+	/// </example>

+	///

+	/// For each test implement a method which interacts with the fixture.

+	/// Verify the expected results with Assertions specified by calling 

+	/// <c>Assert</c> with a bool.

+	/// <code>

+	///    protected void TestAdd() {

+	///        double result= fValue1 + fValue2;

+	///        Assert(result == 5.0);

+	///    }

+	/// </code>

+	/// Once the methods are defined you can run them. The framework supports

+	/// both a static type safe and more dynamic way to run a test.

+	/// In the static way you override the runTest method and define the method

+	/// to be invoked.

+	/// <code>

+	/// protected class AddMathTest: TestCase {

+	///   public void AddMathTest(string name) : base(name) {}

+	///   protected override void RunTest() { TestAdd(); }

+	/// }

+	///

+	/// test test= new AddMathTest("Add");

+	/// test.Run();

+	/// </code>

+	/// The dynamic way uses reflection to implement <c>RunTest</c>. It

+	/// dynamically finds and invokes a method. In this case the name of the

+	/// test case has to correspond to the test method to be run.

+	/// <code>

+	/// test= new MathTest("TestAdd");

+	/// test.Run();

+	/// </code>

+	/// The Tests to be run can be collected into a <see cref="TestSuite"/>.

+	/// NUnit provides different test runners which can run a test suite

+	/// and collect the results.

+	/// A test runner either expects a static property <c>Suite</c> as the entry

+	/// point to get a test to run or it will extract the suite automatically.

+	/// <code>

+	/// public static ITest Suite {

+	///    get {

+	///      suite.AddTest(new MathTest("TestAdd"));

+2002-03-09  Martin Baulig  <martin@gnome.org>

+

+	* DumpCultureInfo.cs: New tool to dump culture info. Incomplete,

+	we need to get unicode support working before we can use this.

+

+2002-03-05  Gaurav Vaish <gvaish@iitk.ac.in>

+

+	* GenerateDelegate.cs: Generates delegates (EventHandler) as

+	  specified. The output is quite simple, a delegate that has

+	  the prototype as -->

+	  public delegate void <given-name>EventHandler(object sender,

+	     <given-name>EventArgs e)

+

+2002-03-01  Martin Baulig  <martin@gnome.org>

+

+	* scan-tests.pl: Catch exceptions when running the tests so that we

+	always run all the tests in a test suite even if some of them fail.

+

+2002-02-27  Martin Baulig  <martin@gnome.org>

+

+	* scan-tests.pl: Moved this script here from ../class/corlib/Test.

+

+2002-02-22  Nick Drochak  <ndrochak@gol.com>

+

+	* makefile: move corcompare to it's own directory to hold multiple

+	class files.  still makes old corcompare for now.  will remove that

+	soon.

+

+2002-02-18  Duncan Mak  <duncan@ximian.com>

+

+	* serialize.cs: When appropriate, changed Type.GetType calls to

+	the faster typeof operator.

+

+2002-02-19  Nick Drochak  <ndrochak@gol.com>

+

+	* corcompare.cs: Reorganized into collaberating classes to analyze

+	and generate reports.  Still needs to find the MonoTODO's, and

+	has a little more prototype code in there, but it's almost done.

+

+	* makefile: output XML file in the tools directory for now.

+

+2002-02-15  Nick Drochak  <ndrochak@gol.com>

+

+	* corcompare.cs: Adding stuff to collect all the missing and todo

+	information need to generate nice looking HTML pages.  Not quite 

+	done and needs some re-org, but Duncan can take a look.

+

+	* sample.xml: an example of how the XML will look that corcompare

+	will generate.  Can be used to start working on the XSLT.

+

+2002-02-13  Nick Drochak  <ndrochak@gol.com>

+

+	* makefile: 'clean' target now removes file generated by CorCompare

+

+2002-02-03  Duncan Mak  <duncan@ximian.com>

+

+	* serialize.cs: Added namespace block.

+

+2002-02-01  Duncan Mak  <duncan@ximian.com>

+

+	* serialize.cs: Added a new tool for serializing objects. It

+	can create new types dynamically, but can only handle

+	arguments that are of primitive types.

+

+2002-01-26  Gaurav Vaish <gvaish@iitk.ac.in>

+

+	* EnumCheckAssemblyCollection.cs,

+	* assemblies.xml:  Files related to EnumCheck checked-in. Now EnumCheck does

+	                   not have any path hardcoded. It takes the assemblies to

+	                   search from a xml files, which by default is assemblies.xml

+

+2002-01-25  Nick Drochak  <ndrochak@gol.com>

+

+	* .cvsignore: ignore .dll files now since we build NUnitCore.dll ourselves

+

+2002-01-18  Duncan Mak  <duncan@ximian.com>

+

+	* EnumCheck.cs: A checkin for Miguel to make EnumCheck not hardcode

+	path to corlib.dll.

+

+2002-01-19  Nick Drochak  <ndrochak@gol.com>

+

+	* makefile: corcompare works again now, so make xml of missing types

+	* CorCompare.cs: use exception that .NET v1 throws to get types in mono corlib

+

+2002-01-18  Nick Drochak  <ndrochak@gol.com>

+

+	* makefile: remove path to beta2 csc.exe.  path to csc.exe must be in PATH instead.

+	don't generate xml from corcompare for now.  it throws an error on v1.0 of .NET

+

+2002-01-17  Nick Drochak  <ndrochak@gol.com>

+

+	* IFaceDisco.cs, XMLUtil.cs: Added new files for interface discovery tool.

+	* makefile: added target for IFaceDisco.exe and added to clean target for same

+

+2002-01-08  John Barnette <jbarn@httcb.net>

+

+	* Removed todo.cs and related makefile data.

+

+

+

+2002-01-07  John Barnette <jbarn@httcb.net>

+

+	

+

+	* makefile: added todo target, fixed EnumCheck target, simplified clean

+

+	

+	* todo.cs: new file.  generates todo list XML and compares assemblies

+

+

+

+2002-01-07  Gaurav Vaish <gvaish@iitk.ac.in>

+

+	* EnumCheck.cs:  Get the numerical values of an enumeration.

+

+2002-01-06  Nick Drochak  <ndrochak@gol.com>

+

+	* corcompare.cs: Catch the FileNotFoundException and handle it nicely.

+

+2002-01-05  Nick Drochak  <ndrochak@gol.com>

+

+	* makefile: build corcompare

+	* corcompare.cs: add new file.  compares an assembly with mscorlib

+TODO

+for CorCompare - 2002/02/25

+

+	* The "methods" for a property's set and get are listed in the methods

+	element.  It would be cool to take them out of there and show that

+	info in the property element, like "SomeProp{ get; set; } if it's missing

+	both.

+

+	* The constructors are just listed as ".ctor" which is not very verbose.

+	What we really need here is the parameter list too, but I couldn't find

+	a way to get the parameters for constructors, only methods.

+

+	* Missing attributes on classes and members are not included at all.

+	

+	* Compare other assemblies besides corlib (then change name of

+	the utility of course :)

+	///

+	/// The usage is as following.  First you have to set some input with

+	/// <code>setInput()</code>, then inflate() it.  If inflate doesn't

+	/// inflate any bytes there may be three reasons:

+	/// <ul>

+	/// <li>needsInput() returns true because the input buffer is empty.

+	/// You have to provide more input with <code>setInput()</code>.

+	/// NOTE: needsInput() also returns true when, the stream is finished.

+	/// </li>

+	/// <li>needsDictionary() returns true, you have to provide a preset

+	///    dictionary with <code>setDictionary()</code>.</li>

+	/// <li>finished() returns true, the inflater has finished.</li>

+	/// </ul>

+	/// Once the first output byte is produced, a dictionary will not be

+	/// needed at a later stage.

+	/// 

+	/// 

+	/// From that document:

+	/// 

+	///      "ADLER32 (Adler-32 checksum)

+	///       This contains a checksum value of the uncompressed data

+	///       (excluding any dictionary data) computed according to Adler-32

+	///       algorithm. This algorithm is a 32-bit extension and improvement

+	///       of the Fletcher algorithm, used in the ITU-T X.224 / ISO 8073

+	///       standard.

+	/// 

+	///       Adler-32 is composed of two sums accumulated per byte: s1 is

+	///       the sum of all bytes, s2 is the sum of all s1 values. Both sums

+	///       are done modulo 65521. s1 is initialized to 1, s2 to zero.  The

+	///       Adler-32 checksum is stored as s2*65536 + s1 in most-

+	///       significant-byte first (network) order."

+	/// 

+	///  "8.2. The Adler-32 algorithm

+	/// 

+	///    The Adler-32 algorithm is much faster than the CRC32 algorithm yet

+	///    still provides an extremely low probability of undetected errors.

+	/// 

+	///    The modulo on unsigned long accumulators can be delayed for 5552

+	///    bytes, so the modulo operation time is negligible.  If the bytes

+	///    are a, b, c, the second sum is 3a + 2b + c + 3, and so is position

+	///    and order sensitive, unlike the first sum, which is just a

+	///    checksum.  That 65521 is prime is important to avoid a possible

+	///    large class of two-byte errors that leave the check unchanged.

+	///    (The Fletcher checksum uses 255, which is not prime and which also

+	///    makes the Fletcher check insensitive to single byte changes 0 -

+	///    255.)

+	/// 

+	///    The sum s1 is initialized to 1 instead of zero to make the length

+	///    of the sequence part of s2, so that the length does not have to be

+	///    checked separately. (Any sequence of zeroes has a Fletcher

+.SH DESCRIPTION
+The \fImonodis\fP program is used to dump the contents a CIL image
+(contained in .EXE files that contain extended PE/COFF CIL code).  
+.SH OPTIONS
+The following Generic options are supported:
+.TP
+.I "--help", "-h"
+Displays usage instructions.
+.TP
+.I "--output=FILENAME"
+Write output into \fIFILENAME\fP.
+.TP
+.I "--mscorlib"
+For non-corlib assemblies, use "mscorlib" as the assembly name. This
+is useful for round-tripping the IL with ilasm.
+.TP
+.I "--assembly"
+Dumps the contents of the assembly table
+.TP
+.I "--assemblyref"
+Dumps the contents of the assemblyref table
+.TP
+.I "--classlayout"
+Dumps the contents of the classlayout table
+.TP
+.I "--constant"
+Dumps the contents of the constant table
+.TP
+.I "--event"
+Dumps the contents of the event table
+.TP
+.I "--exported"
+Dumps the contents of the ExportedTypes table
+.TP
+.I "--fields"
+Dumps the contents of the fields table
+.TP
+.I "--file"
+Dumps the contents of the file table
+.TP
+.I "--interface"
+Dumps the contents of the interface table
+.TP
+.I "--manifest"
+Dumps the contents of the manifest table.
+.TP
+.I "--memberref"
+Dumps the contents of the memberref table
+.TP
+.I "--method"
+Dumps the contents of the method table
+.TP
+.I "--methodsem"
+Dumps the contents of the methodsem table
+.TP
+.I "--module"
+Dumps the contents of the module table
+.TP
+.I "--moduleref"
+Dumps the contents of the moduleref table
+.TP
+.I "--param"
+Dumps the contents of the param table
+.TP
+.I "--property"
+Dumps the contents of the property table
+.TP
+.I "--propertymap"
+Dumps the contents of the propertymap table
+.TP
+.I "--typedef"
+Dumps the contents of the typedef table
+.TP
+.I "--typeref"
+Dumps the contents of the typeref table
+.PP
+If no flags are specified the program dumps the content of the image
+in a format that can be used to rountrip the code. 
+.PP
+.SH ENVIRONMENT VARIABLES
+.TP
+.I "MONO_PATH"
+Provides a search path to mono and mint where to look for library files.
+Directories are separated by the platform path separator (colons on unix). Example:
+.B /home/username/lib:/usr/local/mono/lib
+.PP

+	* interp.c: updates for merge of MonoParam in MonoType.
+
+Thu Aug 23 12:04:34 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* interp.c: removed beforefieldinit check, it's a useless flag.
+	Added a couple more test cases to tests/ dir.
+
+2001-08-22  Miguel de Icaza  <miguel@ximian.com>
+
+	* interp.c (usage): Add version information
+	(ves_pinvoke_method): Typo fix.
+
+Wed Aug 22 20:37:51 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* interp.c: simplified init_class (). Make sure a class
+	is fully initialized before executing a method in the class.
+	Search for the class constructor only on beforefieldinit classes.
+	Implement a bunch of opcodes: br, brfalse, brtrue, beq, bge,
+	bgt, blt, ble, bne.un, bge.un, bgt.un, ble.un, blt.un, stind.i,
+	ldflda, ldsflda, ldelem.i8, stelem.i8, leave.
+
+Wed Aug 22 16:34:03 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* interp.c: Updates for changes in metadata/. Better output in debug mode
+	and in the stack trace. Completed rethrow handling
+
+Tue Aug 21 18:56:19 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* interp.c: new macro INIT_FRAME() to properly
+	initialize a MonoInvocation. Fixed a couple of buglets in exception code:
+	increase stack pointer when pushing the exception for catch blocks,
+	initialize frame->ex_handler to NULL, correctly try all the
+	catch blocks (don't incorrectly fallback on filter handling).
+	Added a couple more checks where we may need to throw an
+	exception. Added more exception creation functions.
+	Changed stackval_from_data() to take the target stackval as
+	argument. Implemented a couple more opcodes.
+	* interp.h: prepare stackval for value type code.
+
+2001-08-21  Miguel de Icaza  <miguel@ximian.com>
+
+	* Makefile.am (mint_LDADD): Renamed interpreter to mint.
+
+2001-08-21  Dietmar Maurer  <dietmar@ximian.com>
+
+	* interp.c (get_named_exception): use the right constructor.
+
+Mon Aug 20 18:58:36 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* interp.c: fix buglet with the leave.s opcode.
+
+2001-08-20  Dietmar Maurer  <dietmar@ximian.com>
+
+	* icall.c: changed everything to support the new calling convention
+
+	* hacks.h: added some macros for FreeBSD 
+
+	* interp.c (get_named_exception): use mono_object_new instead of
+	newobj, initialize the stack before we call the constructor.
+
+Sat Aug 18 12:43:38 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* interp.c, interp.h: added support code to create exceptions.
+	Changed interncal calling convnetion over to MonoInvocation, to support
+	exceptions, walking the stack back and forward and passing the 'this'
+	pointer separately (remove the cludges required before to pass this on the
+	stack). Use alloca heavily for both local vars and a copy of the incoming 
+	arguments. Init local vars to zero.
+	Simplify stackval_from_data() and stackval_to_data() to only take a pointer
+	instead of pointer + offset.
+	Implement a few exceptions-related opcodes and the code to run finally, fault and
+	catch blocks as well as a stack trace if no handler is found.
+	
+2001-08-16  Alex Graveley  <alex@ximian.com>
+
+	* Makefile.am (mono_int_LDADD): Link with ../../libffi/libffi.a
+	instead of ../../libffi/.libs/libffi.a.

+2001-08-10  Dietmar Maurer  <dietmar@ximian.com>
+
+	* interp.c (ves_exec_method): impl CASTCLASS
+
+	* icall.c: moved the internal call stuff to this file
+
+	* interp.c (ves_exec_method): impl. BOX/UNBOX
+	(ves_icall_System_Array_GetValue): impl.
+	(ves_icall_System_Array_SetValue): impl.
+	added myself to Authors
+
+2001-08-09  Dietmar Maurer  <dietmar@ximian.com>
+
+	* implemented arrays, but you will need a modified version of 
+	Array.cs to get arrays working (will commit soon)
+	
+	* interp.c (ves_icall_array_Set): impl.
+	(ves_icall_array_Get): impl.
+	(ves_icall_array_ctor): impl.
+	(ves_icall_System_Array_GetRank): impl.
+	(ves_icall_System_Array_GetLength): impl.

+	(mono_lookup_internal_call): impl.
+
+2001-08-06  Dietmar Maurer  <dietmar@ximian.com>
+
+	* interp.c (ves_exec_method): impl. NEWARR
+	(ves_exec_method): impl. most LDELEM/STELEM opcodes, LDLEN
+	(newarr): impl.
+	(mono_get_ansi_string): impl.
+	(mono_lookup_internal_call): impl.
+	(ves_exec_method): implemented internal calls
+
+2001-08-05  Dietmar Maurer  <dietmar@ximian.com>
+
+	* interp.c (ves_pinvoke_method): removed all static vars.
+
+2001-08-02  Dietmar Maurer  <dietmar@ximian.com>
+
+	* interp.c (ves_exec_method): found a way to do unordered
+	compares, implemented CEE_BNE_UN_S, CEE_BGE_UN_S, CEE_BGT_UN_S, 
+	CEE_BLE_UN_S, CEE_BLT_UN_S
+	
+Wed Aug 1 22:51:38 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* interp.c: handle also MONO_TYPE_CLASS to/from the stack.
+	Change locals to be a memory blob, instead of the structured
+	(but wrong) stackval. Implement bne.un.s opcode. Make the program
+	exit with the error code from Main().
+
+2001-08-01  Dietmar Maurer  <dietmar@ximian.com>
+
+	* interp.c (ves_exec_method): implemented LDSTR
+
+2001-07-31  Miguel de Icaza  <miguel@ximian.com>
+
+	* interp.c (GET_NATI): Switched from using nati_t to cli/types.h
+	m_i type.  Maybe we should rename the types to be m_i_t instead of
+	m_i alone.
+	
+	Make the code compile after I broke it.
+
+Tue Jul 31 23:46:33 CEST 2001 Paolo Molaro <lupus@ximian.com>

+	* interp.c: fix cleanup.
+	* Makefile.am: don't link with disassembler library.
+
+2001-07-31  Miguel de Icaza  <miguel@ximian.com>

+
+	* interp.c: update to use mono_method->name.
+
+Fri Jul 27 20:54:00 CEST 2001 Paolo Molaro <lupus@ximian.com>
+
+	* interp.c: start implementing callvirt. Classes with
+	class constructors are properly initialized when needed.
+	Fix error introduced in version 1.17.
+
+Fri Jul 27 14:03:19 CEST 2001 Paolo Molaro <lupus@ximian.com>

+	constructor after allocationg the object. Implemented load field
+	and store field opcodes (the support functions need to be finished).
+	
+Tue Jul 24 16:51:09 CEST 2001 Paolo Molaro <lupus@ximian.com>
+

+	info on a method invocation: we support now method invocation with
+	multiple (or zero) simple arguments and with or without a return value.

+.PP
+.B mint
+[\-\-help] [\-\-opcode\-count] [\-\-trace] [\-\-traceops] [\-\-profile]
+[\-\-config filename] [\-\-debug method]
+program.exe [arguments...]
+.SH DESCRIPTION
+The \fImint\fP program is an interpreter for ECMA CLI byte codes.  It
+executes the bytecodes contains in 
+.I program.exe
+and optionally passes
+the
+.I arguments
+to it. 
+.SH OPTIONS
+The following Generic options are supported:
+.TP
+.I "--help", "-h"
+Displays usage instructions.
+.TP
+.I "--config filename"
+Load the specified configuration file instead of the default one(s).
+The default files are /etc/mono/config and ~/.mono/config or the file
+specified in the MONO_CONFIG environment variable, if set.
+.TP
+.I "--trace"
+Traces execution showing when methods are entered and left.
+.I "--traceops"
+Traces execution at the instruction level and displays the stack contents.
+.I "--traceclassinit"
+Shows when classes are initialized
+.TP
+.I "--noptr"
+Suppresses printing of pointer addresses in trace output.
+.TP
+.I "--profile"
+Performs runtime profiling of the code and displays statistics at the
+end of execution.
+.TP
+.I "--opcode-count"
+Displays the number of opcodes executed.
+.TP
+.I "--dieonex"
+Aborts execution upon hitting an exception.
+.TP
+.I "--debug method"
+Debugs the method whose name is `method'.  You can specify the method
+like this: `class:method' or `class::method'
+.TP
+.I "--opcode-count"
+Displays the number of opcodes executed
+.PP
+.SH ENVIRONMENT VARIABLES
+.TP
+.I "MONO_PATH"
+Provides a search path to mono and mint where to look for library files.
+Directories are separated by the platform path separator (colons on unix). Example:
+.B /home/username/lib:/usr/local/mono/lib
+.PP
+.SH FILES
+Assemblies are lodaed from the installation lib directory.  If you set
+`prefix' to /usr, the assemblies will be located in /usr/lib.

+2002-06-10  Jaroslaw Kowalski <jarek@atm.com.pl>
+

+
+2002-06-06  Jeffrey Stedfast  <fejj@ximian.com>
+
+	* handles.c (_wapi_handle_new): pthread_once() is not atomic, so
+	if multiple threads all try to call _wapi_handle_new() before the
+	shared data has been initialized, it is possible that we could get
+	into a condition where shared_init() is being executed and later
+	threads will pass by pthread_once() due to the fact that it has
+	already been called and so therefor will attempt to use the shared
+	data before it has been completely initialized. If we instead use
+	a standard mutex locking mechanism around shared_init(), we can
+	avoid the situation entirely. By wrapping the mutex locking in a
+	check to see if we've already initialized the data, we can even
+	avoid wasting resources by having to lock/unlock the mutex in any
+	later calls (the only time we'd have to worry about
+	locking/unlocking is the initial race to call shared_init() at
+	startup).
+
+Sat Jun 1 13:27:11 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* atomic.h: inline asm fixes from Dennis Haney (davh@davh.dk).
+
+Fri May 31 16:21:54 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* daemon.c, handles.c: rename "sun" local var since it's apparently
+	a #define on Solaris.
+
+Fri May 31 15:40:14 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* daemon-messages.c: work-around MSG_NOSIGNAL missing on some
+	platforms.
+
+2002-05-15  Dick Porter  <dick@ximian.com>
+
+	* wait.c: Fix a deadlock in WaitForMultipleObjects
+
+2002-05-14  Dick Porter  <dick@ximian.com>
+
+	* io.c: Fix a cut&paste error, found by
+	Jaroslaw Kowalski <jarek@atm.com.pl>
+
+2002-05-10  Dan Lewis  <dihlewis@yahoo.co.uk>

+	* processes.c:

+	* Makefile.am: Remove now-unused file wait-private.h
+
+2002-05-08  Dick Porter  <dick@ximian.com>
+
+	* shared.c: Better error messages, and report when daemon
+	connection fails rather than blocking forever.  Do some more
+	shared memory sanity checking.
+
+	* handles.c: Better error messages when connecting to shared
+	memory and the handle daemon.  Fall back to non-shared handles if
+	an error occurs.  Set the default back to 'shared handles'.  Fix a
+	crashing bug in scratch space allocation that mangled the block
+	headers.
+
+2002-05-07  Miguel de Icaza  <miguel@ximian.com>
+
+	* handles.c (shared_init): Disable SHM for now, people have too
+	many problems with this, and the diagnostics are not helping.
+
+2002-05-06  Dan Lewis  <dihlewis@yahoo.co.uk>
+
+	* io.c: CreateFile sets win32 last error.
+

+	* semaphore-private.h: 
+	* sockets.c: 
+	* socket-private.h: 
+	* events.c: 
+	* event-private.h: Simplify the WapiHandleOps struct: take out all
+	the file-specific entries, leaving just the items that operate on
+	handles themselves.  Split the close operation into shared and
+	private parts: shared close is called by the daemon.
+
+	* handles.c: As above, but also pass handle allocation, ref and
+	unref operations to the daemon.  Populate the handle_ops array at
+	compile time, because the daemon needs to call ops on handles too.
+	Don't bother to track open handle counts any more, the daemon does
+	that.
+	
+	* threads.c: 
+	* thread-private.h: As above, but also make the thread data
+	handle-private.
+
+	* shared.c: Fork a handle daemon if the calling process created
+	the shared memory segment.
+
+	* daemon.c:
+	* daemon-messages.c:
+	* daemon-messages.h:
+	* Makefile.am: Build a daemon to manage handle allocation and
+	destruction without needing to lock the shared memory
+
+2002-04-30  Jeffrey Stedfast  <fejj@ximian.com>
+
+	* atomic.c: Changed to use a normal mutex rather than a spinlock
+	since a lot of platforms seem to not have them :\
+
+2002-04-30  Dick Porter  <dick@ximian.com>
+
+	* Completely rewrote the handle waiting code: removed the helper
+	thread and its attendant complexity.  All handle waiting is now
+	abstracted into the WaitForSingleObject() and
+	WaitForMultipleObjects() functions.
+
+	* Implemented inter-process sharing of handles using sysv shared
+	memory.  This makes handles even more opaque, with a handle now
+	just an index into an array.
+	
+2002-04-25  Dan Lewis  <dihlewis@yahoo.co.uk>
+

+ * Code to support inter-process sharing of handles.
+ *
+ * I thought of using an mmap()ed file for this.  If linuxthreads
+ * supported PTHREAD_PROCESS_SHARED I would have done; however without
+ * that pthread support the only other inter-process IPC
+ * synchronisation option is a sysV semaphore, and if I'm going to use
+ * that I may as well take advantage of sysV shared memory too.
+ * Actually, semaphores seem to be buggy, or I was using them
+ * incorrectly :-).  I've replaced the sysV semaphore with a shared
+ * integer controlled with Interlocked functions.
+
+ * mmap() files have the advantage of avoiding namespace collisions,
+ * but have the disadvantage of needing cleaning up, and also msync().
+ * sysV shared memory has a really stupid way of getting random key
+ * IDs, which can lead to collisions.
+ *
+ * I deliberately don't ever delete the shared memory: I'd like to
+ * have been able to set the shared memory segment to destroy itself
+ * on last close, but it doesn't support that. (Setting IPC_RMID on a
+ * segment causes subsequent shmat() with the same key to get a new
+ * segment :-( ).  The function to delete the shared memory segment is
+ * only called from a debugging tool (mono/handles/shmdel).
+ *
+ * w32 processes do not have the POSIX parent-child relationship, so a
+ * process handle is available to any other process to find out exit
+ * status.  Handles are destroyed when the last reference to them is
+ * closed.  New handles can be created for long lasting items such as
+ * processes or threads, and also for named synchronisation objects so
+ * long as these haven't been deleted by having the last referencing
+ * handle closed.

+
+	Work around a hard-to-fix bug in GDB and create a single dwarf/stabs
+	file for all assemblies.  Currently, the JIT doesn't put all methods
+	from a single assembly into a continuous region of memory.  We were

+	GDB's symbol tables get messed up when it reads more than one such file.

+	format to use.
+	(mono_debug_open_file): Added MonoDebugFormat argument.
+	(mono_debug_make_symbols): Don't take an argument to make it easier to call

+	it'll always write a complete debugging file.
+
+	* debug.c: Splitted this file into a general part which remains in this file
+	and the debugging format specific parts debug-stabs.c and debug-dwarf2.c.

+	(record_line_number, debug_generate_method_lines): New private functions.
+	(mono_debug_open_ass): Renamed to mono_debug_open_assembly; this function now

+	mono_debug_open_assembly_dwarf2).
+	(mono_debug_make_symbols): Calls mono_debug_write_assembly_stabs/dwarf2(). It's
+	now safe to call this function multiple times.
+	(mono_debug_get_type): New public function. This takes a `MonoClass *' and
+	returns an unique index for this type. It's used to ensure that we only write
+	each class once to the debugging file.
+	(mono_debug_add_method, mono_debug_add_type): Store all the data in an internal
+	data structure, but don't directly write to the debugging file. This is done
+	later from mono_debug_write_assembly().
+
+	* jit.c (main): Added "--dwarf" command line argument to generate DWARF 2
+	debugging output. Call mono_debug_close() on cleanup if necessary.
+

+
+	* debug-stabs.c: Added the stabs type generation stuff which was

+
+2002-03-13  Martin Baulig  <martin@gnome.org>
+
+	* debug-stabs.c, debug-dwarf2.c: New files containing my new
+	debugging code. They're now in CVS, but not yet used anywhere.

+	describe and match a method when debugging.
+
+2002-03-10  Martin Baulig  <martin@gnome.org>
+
+	* emit-x86.c (arch_compile_method): When emitting stabs debugging
+	output, put a nop instruction at the start of all functions so that
+	the adresses won't change when using --debug.
+
+	* debug.c (mono_debug_add_method): `tree->cli_addr' is an offset into
+	the bytecode area, stabs needs a line number in the .il file. Use the
+	new info->moffsets to get the line number.
+	(AssemblyDebugInfo): Added `total_lines' and `moffsets' fields.
+	`moffsets' is an array of `total_lines' fields (total number of lines
+	in the .il file); for each line in the .il field, this array contains
+	the bytecode offset if it's an "IL_xxxx" line, -1 if it's the last line
+	of a method and 0 otherwise.
+	(debug_load_method_lines): Read the whole .il file and initialize the
+	info->moffsets field.

+
+2002-07-07  Radek Doulik  <rodo@ximian.com>
+
+	* reflection.c: swap box_val and not val

+	bug with the mingw developers for them to wrap OpenThread().
+
+2002-07-03  Dick Porter  <dick@ximian.com>
+
+	* threads.c: Store thread IDs instead of handles, because
+	GetCurrentThread() returns a pseudohandle and therefore stores
+	useless values.  mono_thread_cleanup() continues checking the
+	array of threads until it is empty, to cope with subthreads
+	spawning new threads after the main thread has finished.

+
+	* object.c (mono_ldstr): swap bytes here, it's probably not the
+	best place, but works for me now, I'll redo it once I know mono

+
+	* mono-endian.h (read16): use just glib macros for both endians

+	found. Handle simple arrays in assQualifiedName.
+	* object.h: add a struct to represent an Exception.
+	* reflection.c: output call convention in method signature.
+	Add code to support P/Invoke methods and fixed offsets for fields.
+

+
+	* decimal.c, decimal.h: mono_double2decimal() get the sign bit from

+
+2001-08-24  Dietmar Maurer  <dietmar@ximian.com>

+
+	* metadata.h, row_indexes.h: added header with enumerations to use

+	wrong) MonoFieldType struct and use MonoParam instead. Changed
+	mono_metadata_parse_field_type () to use common code for parsing.
+	Added mono_metadata_typedef_from_field () and
+	mono_metadata_typedef_from_method () to lookup a typedef index from a

+
+	* metadata.c (mono_metadata_parse_field_type): Implement.

+.SH NAME
+monoburg \- code generator generator
+.SH SYNOPSIS
+.PP
+.B monoburg
+[\-h]  
+[\-d HEADER]
+FILE
+.SH DESCRIPTION
+The \fImonoburg\fP program is used to generate tree pattern matchers 
+from BURG specifications. \fImonoburg\fP accepts the following EBNF grammar.
+.PP
+.nf
+.RS
+.ft CW
+spec:      ccode `%%' { dcl } [`%%' ccode]
+
+dcl:       `%start' nonterm
+           `%term' { identifier [`=' integer] }
+           nonterm `:' tree [cost] [ `{' ccode `}' ] [costfunc]
+
+tree:      term `(' tree `,' tree `)'
+           term `(' tree `)'
+           term
+           nonterm
+
+cost:      `"' string '"'
+           integer
+
+costfunc: `cost' `{' ccode `}'
+.RE
+.fi
+.PP
+Where \fIccode\fP is arbitrary C code. \fIcost\fP and \fIcostfunc\fP are
+used mutually exclusive, you can't use both in one rule. \fIcost\fP must be a C
+expression, whereas \fIccode\fP inside \fIcostfunc\fP is the body of a C 
+function. Here are some example rules:
+.PP
+.nf
+.RS
+.ft CW
+# define some terminal
+%term Fetch Four Mul Plus
+
+# this rule uses fixed costs
+addr: Plus (con, Mul (Four, reg)) 2 
+{
+        printf ("Emit your code here.");
+} 
+
+# this one computes costs inside a function
+reg:  Fetch (addr)  
+{
+        printf ("Tree address is %p", tree);
+
+} cost {
+	int c;
+
+	c = 1; /* calculate the costs here */
+
+	return c;
+}
+.RE
+.fi
+.PP
+
+.SH OPTIONS
+The following options are supported:
+.TP
+.I "-h"
+Displays usage instructions.
+.TP
+.I "-d HEADER"
+Writes a separate header file which contains all monoburg definitions.
+.PP
+.SH AUTHOR
+monoburg was written by Dietmar Maurer. It is based on the papers from 
+Christopher W.\ Fraser, Robert R.\ Henry and Todd A.\ Proebsting:
+"BURG - Fast Optimal Instruction Selection and Tree Parsing" and
+"Engineering a Simple, Efficient Code Generator Generator".

+
+Thu Jul 25 13:59:34 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* mono-digest.h, mono-md5.c, mono-sha1.c: MD5 and SHA1
+	implementations.
+
+Mon Jun 3 15:59:31 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* strtod.c: make __bsd_dtoa() always return malloc()ed memory.
+
+Mon Jun 3 15:42:50 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* monobitset.c, monobitset.h: documentation and fixes from
+	Dennis Haney.
+
+Sat Jun 1 14:10:23 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* monobitset.c: fix my screwup pointed out by Lawrence Pit
+	(loz@cable.a2000.nl).
+
+Fri May 31 15:34:18 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* monobitset.c, monobitset.h: fixes. added mono_bitset_foreach().
+
+Wed May 22 12:42:06 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* monobitset.c: use our own bit_nth_lsf since the glib one is buggy.
+	Add more tests. mono_bitset_find_first (set, -1) will work correctly
+	now.
+
+2002-05-09  Dietmar Maurer  <dietmar@ximian.com>
+
+	* monobitset.c: use memcmp instead of memcpy
+
+Thu May 9 17:23:17 CEST 2002 Paolo Molaro <lupus@ximian.com>
+
+	* monobitset.c, monibitset.h: bit set data structure.
+	Not included in the build yet because the jit has some symbol clashes
+	with it.
+
+Mon Mar 25 12:50:53 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* First checkin: libmonoutils is meant to hold some utility
+	data structures and bits that are usefult to the rest of the project
+	and don't require metadata/runtime support.
+	mono-hash is a GC-safe hash table: i.e. you can store GC-allocated
+	data in it.

+SHA-1 in C
+By Steve Reid <sreid@sea-to-sky.net>
+100% Public Domain
+
+-----------------
+Modified 7/98 
+By James H. Brown <jbrown@burgoyne.com>
+Still 100% Public Domain
+
+Corrected a problem which generated improper hash values on 16 bit machines
+Routine mono_sha1_update changed from
+	void mono_sha1_update(MonoSHA1Context* context, unsigned char* data, unsigned int
+len)
+to
+	void mono_sha1_update(MonoSHA1Context* context, unsigned char* data, unsigned
+long len)
+
+The 'len' parameter was declared an int which works fine on 32 bit machines.
+However, on 16 bit machines an int is too small for the shifts being done
+against
+it.  This caused the hash function to generate incorrect values if len was
+greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of mono_sha1_update().
+
+Since the file IO in main() reads 16K at a time, any file 8K or larger would
+be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
+"a"s).
+
+I also changed the declaration of variables i & j in mono_sha1_update to 
+unsigned long from unsigned int for the same reason.
+
+These changes should make no difference to any 32 bit implementations since
+an
+int and a long are the same size in those environments.
+
+--
+I also corrected a few compiler warnings generated by Borland C.
+1. Added #include <process.h> for exit() prototype
+2. Removed unused variable 'j' in mono_sha1_final
+3. Changed exit(0) to return(0) at end of main.
+
+ALL changes I made can be located by searching for comments containing 'JHB'

+/* strtod for IEEE-, VAX-, and IBM-arithmetic machines.
+ *
+ * This strtod returns a nearest machine number to the input decimal
+ * string (or sets errno to ERANGE).  With IEEE arithmetic, ties are
+ * broken by the IEEE round-even rule.  Otherwise ties are broken by
+ * biased rounding (add half and chop).
+ *
+ * Inspired loosely by William D. Clinger's paper "How to Read Floating
+ * Point Numbers Accurately" [Proc. ACM SIGPLAN '90, pp. 92-101].
+ *
+ * Modifications:
+ *
+ *	1. We only require IEEE, IBM, or VAX double-precision
+ *		arithmetic (not IEEE double-extended).
+ *	2. We get by with floating-point arithmetic in a case that
+ *		Clinger missed -- when we're computing d * 10^n
+ *		for a small integer d and the integer n is not too
+ *		much larger than 22 (the maximum integer k for which
+ *		we can represent 10^k exactly), we may be able to
+ *		compute (d*10^k) * 10^(e-k) with just one roundoff.
+ *	3. Rather than a bit-at-a-time adjustment of the binary
+ *		result in the hard case, we use floating-point
+ *		arithmetic to determine the adjustment to within
+ *		one bit; only in really hard cases do we need to
+ *		compute a second residual.
+ *	4. Because of 3., we don't need a large table of powers of 10
+ *		for ten-to-e (just some small tables, e.g. of 10^k
+ *		for 0 <= k <= 22).

+/* dtoa for IEEE arithmetic (dmg): convert double to ASCII string.
+ *
+ * Inspired by "How to Print Floating-Point Numbers Accurately" by
+ * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90, pp. 92-101].
+ *
+ * Modifications:
+ *	1. Rather than iterating, we use a simple numeric overestimate
+ *	   to determine k = floor(log10(d)).  We scale relevant
+ *	   quantities using O(log2(k)) rather than O(k) multiplications.
+ *	2. For some modes > 2 (corresponding to ecvt and fcvt), we don't
+ *	   try to generate digits strictly left to right.  Instead, we
+ *	   compute with fewer bits and propagate the carry if necessary
+ *	   when rounding the final digit up.  This is often faster.
+ *	3. Under the assumption that input will be rounded nearest,
+ *	   mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22.
+ *	   That is, we allow equality in stopping tests when the
+ *	   round-nearest rule will give the same floating-point value
+ *	   as would satisfaction of the stopping test with strict
+ *	   inequality.
+ *	4. We remove common factors of powers of 2 from relevant
+ *	   quantities.
+ *	5. When converting floating-point integers less than 1e16,
+ *	   we use floating-point arithmetic rather than resorting
+ *	   to multiple-precision integers.
+ *	6. When asked to produce fewer than 15 digits, we first try
+ *	   to get by with floating-point arithmetic; we resort to
+ *	   multiple-precision integer arithmetic only if we cannot
+ *	   guarantee that the floating-point calculation has given
+ *	   the correctly rounded result.  For k requested digits and
+ *	   "uniformly" distributed input, the probability is
+ *	   something like 10^(k-15) that we must resort to the long
+ *	   calculation.

+2002-02-20  Dick Porter  <dick@ximian.com>
+
+	* Makefile.am:
+	* wrapper.c: Windows portability fixes (sometimes just ifdeffing
+	problem code out for now).
+
+2002-02-16  Jeffrey Stedfast  <fejj@ximian.com>
+
+	* wrapper.c (mono_wrapper_fstat): The MonoWrapperStat namespace is
+	mst_ now, so update this code. Also fix a copy/paste-o that
+	assigned st.st_ctime to buf->mst_mtime.
+	(mono_wrapper_stat): Same here.
+
+	* genwrapper.pl: Solaris does some nasty macro hadckery action for
+	st_[a,c,m]time and so lets namespace our wrapper members as
+	mst_[a,c,m]time to avoid namespace problems.
+
+Sun Feb 10 14:18:50 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* genwrapper.pl: use pkg-config instead of glib-config (pointed out by
+	Eric Molitor <eric@brainfood.com>).
+
+2002-01-31  Dietmar Maurer  <dietmar@ximian.com>
+
+	* wrapper.c (mono_wrapper_readdir): ugly hack - we must return a String
+	instead of a char* 
+
+Thu Jan 24 17:41:06 CET 2002 Paolo Molaro <lupus@ximian.com>
+
+	* glob.c: fix typo.
+
+2002-01-23  Miguel de Icaza  <miguel@ximian.com>
+
+	* glob.c (mono_glob_compile): Make the glob expression contain ^
+	and $ at the beginning and end respectively.
+
+	* genwrapper.pl: Added wrappers for the mono_glob functions.
+
+	* glob.c: New file, with globing functions used by the Directory
+	code. 
+
+	* wrapper.c: Changed things so that we can propagate ERRNO back. 
+
+	Include stdio.h and unistd.h to remove a couple of warnings.
+
+	* genwrapper.pl: Added support for flagging non-CLS compliant
+	classes and structs with CLSCompliant(false).
+
+	Added mkdir, rmdir and rename wrappers.
+
+2001-09-20  Dietmar Maurer  <dietmar@ximian.com>
+
+	* wrapper.c: added declaration of environ
+
+2001-09-07  Nick Drochak  <ndrochak@gol.com>
+
+	* Makefile.am: Use '=' to set CLEANFILES instead of '+=' since 
+		it's the first assignment.
+	
+	* ChangeLog: added this file.

+You can browse the status of the class library and see who has
+registered to work on what parts of the system.  You can view either
+by maintainer or by namespace.
+<p>
+The tables represent things that contributors are working on.  We
+register the date when they started working on a particular class, and
+whether a contributor has sent code in (the "implementation" column).  
+<p>
+If you want to contribute to Mono, you want to pick a class which is
+not listed here.  Alternatively, you can contact the maintainer of a
+class if you want for example to help him improve his code, make it
+faster, better, provide documentation or make comments.
+<p>
+Sometimes contributors will get too busy with other tasks, so they
+will abandon their work on a class.  That is why we keep track of the
+time when they "reserve" a class to work on.  If the contributor gets
+too busy, we will know if someone else can work on it

+* ADO.NET
+
+	The coordinator for the ADO.NET implementation is <a
+	href="mailto:rodrigo@ximian.com">Rodrigo Moya</a>, with
+	the collaboration of <a href="mailto:danmorg@sc.rr.com">Daniel
+	Morgan</a> and <a href="mailto:tim@timcoleman.com">Tim Coleman</a>.
+	
+
+* Action plan
+
+	The current plan to implement ADO.NET is as follows:
+
+	<b>Step 1:</b> Initial <a href="http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemdatasqlclient.asp?frame=true">System.Data.SqlClient</a> Provider:
+
+	<ul>
+		* Initial implementation of System.Data.SqlClient is based on
+		  the <a href="http://www.postgresql.org/idocs/">PostgreSQL C API</a> which is a
+		  client API to the PostgreSQL DBMS.  PostgreSQL was chosen so we could quickly
+		  create and test the System.Data classes.
+		  
+		* Once the <a href="http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemdatasqlclient.asp?frame=true">System.Data.SqlClient</a>
+		  code is functional and is usable by other people, we willl move it to
+		  Mono.Data.PostgreSQL, and will convert the existing
+		  System.Data.SqlClient to be just a wrapper around
+		  Mono.Data.PostgreSQL.  
+
+	</ul>
+
+	<b>Step 2:</b> <a href="http://msdn.microsoft.com/library/en-us/cpref/html/frlrfSystemDataOleDb.asp?frame=true">System.Data.OleDb</a> Provider:
+		
+	<ul>
+		* <p>On Unix systems: System.Data.OleDb will use the
+		<a href="http://www.gnome-db.org/">LibGDA</a>
+		 engine. 
+
+		  <p>LibGDA is a data access engine like ADO/OLE-DB, but for Unix.  The 
+		  GDA in libGDA stands for GNU/GNOME Data Access, but it does not require GNOME.
+		  It only requires glib2 and libxml2.  LibGDA is used by 
+		  libgnomedb, GNOME-DB, and gaSQL.  
+		  
+		  <p>There is work under way to get libgda working under 
+		  Windows using Cygwin by the GNOME-DB developers.
+		  
+		  <p>LibGDA has providers for MySQL, PostgreSQL, XML, ODBC,
+		  and MDB Tools (MS Access support).
+
+		* On Windows systems: System.Data.OleDb will use OLE-DB as
+		  its engine.  It may have the option of using libgda too.
+	</ul>
+
+	<b>Step 3:</b> <a href="http://msdn.microsoft.com/library/en-us/cpref/html/frlrfsystemdatasqlclient.asp?frame=true">System.Data.SqlClient</a> Provider:
+
+	<ul>
+		* <p>System.Data.SqlClient will then become a managed
+		  provider for Microsoft SQL Server, both on Windows and
+		  Linux, to be compatible with applications written
+		  for the Microsoft .NET Development Framework.
+		  
+		  <p>Once Step 1 has been completed and the PostgreSQL
+		  provider support has been moved to its own place at 
+		  System.Data.PostgreSQL, we will use 
+		  <a href="http://www.freetds.org/">FreeTDS</a> as the basis
+		  for providing access to Microsoft SQL Server databases.
+		  
+		  <P>FreeTDS is a C API for Unix and Windows that implements 
+		  the TDS (Tabular Data Stream) protocol used in accessing 
+		  Microsoft SQL Server and Sybase databases.  A .NET Data Provider could be
+		  created for Sybase databases as well, but this would be put in Mono.Data.Sybase.
+	</ul>
+
+	<b>Step 4:</b> <a href="http://msdn.microsoft.com/downloads/sample.asp?url=/MSDN-FILES/027/001/668/msdncompositedoc.xml&frame=true">System.Data.Odbc</a> Provider:
+	
+	<ul>
+		* We will create a .NET Managaed Provider for ODBC
+		  in System.Data.Odbc for those using ODBC.
+		  On Unix and Windows, <a href="http://www.unixodbc.org/">unixODBC</a> mabye used.
+		  iODBC is an alternative to using unixODBC.
+		  
+		  <p>unixODBC works on Unix and Windows.  Well, I have not actually 
+		  used it on Cygwin, but it does build and install without problems.  
+		  
+		  <p>unixODBC has providers for:
+		  Oracle, Microsoft SQL Server and Sybase via FreeTDS, 
+		  MySQL, PostgreSQL, Informix, IBM DB2 (Universal Database), 
+		  Interbase, miniSQL (mSQL), AdabasD, Empress, YARD SQL, and others.
+		  
+	</ul>
+
+	<b>Step 5:</b> Other System.Data providers:
+
+	<ul>
+		* <p>The idea in Microsoft .NET System.Data is to have
+		  a managed provider for each supported DBMS.  System.Data.SqlClient
+		  for Microsoft SQL Server.  
+		  System.Data.OracleClient for Oracle 8i and 9i.
+
+		  <p>We will need to have Mono.Data.MySQL, Mono.Data.PostgreSQL,
+		  Mono.Data.DB2, and Mono.Data.miniSQL. Others,
+		  of course, are welcomed.
+		  		  
+		  <p>System.Data has been designed so 
+		  non-database providers can be created too.		  
+	</ul>
+	
+* Current Status
+
+	<p>We are working on Steps 1, 2, and 5.  We have only just begun on
+	steps 2 and 5 though.  We still have tons and tons of stuff to do.
+	If you have any ideas, let us know.
+	
+	<p>For Step 1, the PostgreSQL is starting to come together - it 
+	still needs a lot of work.
+	
+	<p>For Step 2, Rodrigo Moya has begun System.Data.OleDb which will use libgda
+	which is an OLE-DB/ADO data access for Unix.  The C-Sharp bindings to libgda
+	currently work - meaning they can compile, run, and you can connect to a
+	PostgreSQL database via libgda via the C-Sharp bindings to libgda.  He has also
+	added class stubs for System.Data.OleDb to cvs.
+	
+	<p>For Step 3, we need someone to start the FreeTDS .NET Data Provider so
+	we can have data access to Microsoft SQL Server and Sybase databases, or either
+	add the support in libgda.
+	
+	<p>For Step 4, we need someone to start the unixODBC .NET Data Provider, or add
+	the support in libgda.
+	
+	<p>For Step 5, we have just begun creating a Mono.Data .NET Provider - a MySQL
+	.NET Provider that uses the MySQL C Client Library.  This provider is 
+	found in Mono.Data.MySql.  We can currently connect and do a SQL INSERT and insert
+	a row into a MySQL database.  However, it currently only works on Cygwin because
+	the MySQL client library libmySQL.dll is different 
+	from the library on Linux libmysqlclient.dll.  Another problem, mysql thread functions
+	do not load for some reason.  Also, the provider only runs if you use "mint" (the Mono
+	runtime interpreter).  It does not work on "mono" (the Mono Just-In-Time compiler).
+	The C# Bindings to MySQL are thanks to Brad Meril.
+		
+	<p>We are able to do simple CREATE TABLE, DROP TABLE, UPDATE, INSERT, and
+	DELETE SQL commands using the ExecuteNonQuery method in SqlCommand.  
+	
+	<p>We can execute multiple queries and do a NextResult() in SqlDataReader()
+	to get the next result set.  
+	
+	<p>We are also able to do simple aggregate functions, 
+	ie, count(), sum(), min(), and max() 
+	in a simple SELECT SQL query using the ExecuteScalar() now.  
+	
+	<p>We are also able to retrieve data with a simple SELECT SQL query 
+	using ExecuteReader() which returns a SqlDataReader.  We are able to
+	use GetSchemaTable() to get the meta data about the table columns.  
+	We are able	to Read() to get each row from the result set.  
+	
+	<p>Here is a sample of code that is based on PostgresTest.cs and
+	TestSqlDataReader.cs tests:
+<pre>
+ 
+ static void SelectData (IDbConnection cnc) {
+	
+	IDbCommand selectCommand = cnc.CreateCommand();
+	IDataReader reader;
+
+	selectCommand.CommandType = CommandType.Text;
+	selectCommand.CommandText = 
+		"select * from pg_user;" + 

+		"select * from pg_tables;" + 

+		"select * from pg_database";

+
+	reader = selectCommand.ExecuteReader ();
+
+	do {

+		// get the DataTable that holds

+		// the schema

+		DataTable dt = rdr.GetSchemaTable();

+

+		if(rdr.RecordsAffected != -1) {

+			// Results for 

+			// SQL INSERT, UPDATE, DELETE Commands 

+			// have RecordsAffected >= 0

+			Console.WriteLine("Result is from a SQL Command (INSERT,UPDATE,DELETE).  Records Affected: " + rdr.RecordsAffected);

+		}

+		else if (dt == null)

+				Console.WriteLine("Result is from a SQL Command not (INSERT,UPDATE,DELETE).   Records Affected: " + rdr.RecordsAffected);

+		else {

+			// Results for

+			// SQL not INSERT, UPDATE, nor DELETE

+			// have RecordsAffected = -1

+			Console.WriteLine("Result is from a SQL SELECT Query.  Records Affected: " + rdr.RecordsAffected);

+		

+			// Results for a SQL Command (CREATE TABLE, SET, etc)

+			// will have a null reference returned from GetSchemaTable()

+			// 

+			// Results for a SQL SELECT Query

+			// will have a DataTable returned from GetSchemaTable()

+

+			results++;

+			Console.WriteLine("Result Set " + results + "...");

+                        			

+			// number of columns in the table

+			Console.WriteLine("   Total Columns: " +

+				dt.Columns.Count);

+

+			// display the schema

+			foreach (DataRow schemaRow in dt.Rows) {

+				foreach (DataColumn schemaCol in dt.Columns)

+					Console.WriteLine(schemaCol.ColumnName + 

+						" = " + 

+						schemaRow[schemaCol]);

+				Console.WriteLine();

+			}

+

+			int nRows = 0;

+			string output, metadataValue, dataValue;

+			// Read and display the rows

+			Console.WriteLine("Gonna do a Read() now...");

+			while(rdr.Read()) {

+				Console.WriteLine("   Row " + nRows + ": ");

+					

+				for(c = 0; c < rdr.FieldCount; c++) {

+					// column meta data 

+					DataRow dr = dt.Rows[c];

+					metadataValue = 

+						"    Col " + 

+						c + ": " + 

+						dr["ColumnName"];

+						

+					// column data

+					if(rdr.IsDBNull(c) == true)

+						dataValue = " is NULL";

+					else

+						dataValue = 

+							": " + 

+							rdr.GetValue(c);

+				

+					// display column meta data and data

+					output = metadataValue + dataValue;					

+					Console.WriteLine(output);

+				}

+				nRows++;

+			}

+			Console.WriteLine("   Total Rows: " + 

+				nRows);

+		}	

+	} while(rdr.NextResult());

+	Console.WriteLine("Total Result sets: " + results);

+			

+	rdr.Close();

+ }
+
+</pre>
+	
+	<p>We are able to get 
+	String data (char, character, text, varchar), Int16 (smallint),
+	Int32 (integer), Int64 (bigint), DateTime (time, date, timestamp),
+	Boolean (boolean), Single (float), and Double (double).
+	More data types will come later.  Note, the types that do work still 
+	need thorough testing.
+	
+	<p>Rows that are returned which contain columns that are NULL are handled now. 
+	The SqlDataReader method IsDBNull() needs to be called to determine 
+	if a field IS NULL before trying to read data from that field.
+	
+	<p>Calling PostgreSQL stored procedures works.  It does not work perfectly.  It may not
+	even work to specification - yet.  If you want to test it yourself, look at
+	TestSqlDataReader.cs or PostgresTest.cs in
+	mcs/class/System.Data/Test.  
+	
+	<p>Below, I have some sample code you can
+	use to call a PostgreSQL stored procedure named "version".  This stored
+	procedure returns a string containing the PostgreSQL server version.  Notice
+	the CommandType is StoredProcedure and the method ExecuteScalar() is called.
+	
+	<p>ExecuteScalar() is a lightweight method in class SqlCommand that only returns
+	one row and one column as one object - even if there is more than row or column.
+	
+<pre>
+ static string GetDatabaseServerVersion (SqlConnection cnc) 
+ {			 
+	SqlCommand cmd = cnc.CreateCommand ();
+	string data;
+
+	cmd.CommandType = CommandType.StoredProcedure;
+	cmd.CommandText = "version";
+							
+	data = (string) cmd.ExecuteScalar ();
+
+	return data;
+ }
+</pre>
+			
+	<p>We have the beginnings of Parameters support PostgreSQL.  Only
+	Input Parameters are currently supported.  Output, Input/Output,
+	and Return parameters still need to be done.
+	
+	<p>A lot of functionality in System.Data is missing, but the 
+	infrastructure is starting to come together.
+	
+	<p>A lot of Exceptions need to be thrown for various exceptions.  However,
+	SqlException, SqlErrorCollection, and SqlError have been partially
+	implemented.
+	
+	<p>Tim Coleman and Rodrigo Moya got the beginnings of the
+	SqlDataAdapter/DataSet/DataTable/DataRow to work.  Currently, 
+	the SqlDataAdapter can Fill() relational data into a DataTable in a DataSet.
+	See the test mcs/class/System.Data/Test/TestSqlDataAdapter.cs to see it in action.
+	Below, I show a snippets from the test:
+	
+<pre>
+ string connectionString;
+ string sqlQuery;
+ SqlDataAdapter adapter;
+ DataSet dataSet = null;
+
+ connectionString =
+	"host=localhost;" +
+	"dbname=test;" +
+	"user=postgres";
+						
+ sqlQuery = "select * from pg_tables";
+
+ adapter = new SqlDataAdapter (sqlQuery, 
+			connectionString);
+ 				
+ dataSet = new DataSet ();
+
+ adapter.Fill (dataSet);
+			
+ if (dataSet != null) {
+	foreach (DataRow row in dataSet.Tables["Table"].Rows)
+		Console.WriteLine("tablename: " + row["tablename"]);
+ }
+</pre>	
+	
+	<p>We do need help on the DataSet/DataAdaptor/DataTable/DataRelation/XML 
+	functionality so we	can integrate with 
+	the ASP.NET controls and Windows.Forms controls by allowing the controls to bind 
+	to a data source.  Gonzalo, Gaurav, Leen, Patrik, Duncan, and others are 
+	working very hard on the ASP.NET support. If you want to help, 
+	contact <a href="mailto:gonzalo@ximian.com">Gonzalo Paniagua Javier</a>
+	
+	<P>Need to add XML support in System.Data.  This involves working on
+	the classes: DataSet and XmlDataDocument and the ExecuteXmlReader() in SqlCommand.
+	
+	<p>The System.Data.dll gets built with the rest of the class library.
+	To compile the System.Data.dll assembly separately, you need:
+
+	<b>On Unix</b>
+
+	<ul>
+		* update your mono sources. Be sure you have latest mcs.exe
+		  and .dll's, since there have been many fixes needed for
+		  compilation on Linux.
+
+		* compile System.Data.dll:
+<pre>
+ cd mcs/class/System.Data<br>
+ mcs --target library -o System.Data.dll @list
+</pre>
+	</ul>
+
+	<b>On Windows</b>
+
+	<ul>
+		* update your mono sources. Be sure you have latest mcs.exe
+		  and .dll's.  You can use the same method as Linux, 
+		  or you can use NAnt.
+
+		* To use NAnt:
+
+<pre>
+ cd mcs/class/System.Data
+ ../../nant/NAnt.exe
+</pre>
+			
+			This will automatically copy the System.Data.dll to Test.
+			If you need to do a clean for the System.Data.dll assembly,<br><br>
+
+<pre>			
+ cd mcs/class/System.Data
+ ../../nant/NAnt.exe clean
+</pre>
+	</ul>
+
+* Testing
+
+	<p>In order to test System.Data.SqlClient, you will need to have
+	access to a remote PostgreSQL DBMS, or you will have to install 
+	one locally.  PostgreSQL is the DBMS used for the initial 
+	implementation of System.Data.SqlClient.
+		
+	<p>Why?  Because it is open source, has a client 
+	library that is easy to use, PostgreSQL is easy to install on
+	Unix and Windows (using the Cygwin install program), not difficult to setup after
+	installation, and it runs under: Linux, 
+	Windows (via cygwin and ipc-daemon), Unix, and
+	others.  This allowed us to create the
+	System.Data functionality in Mono much quicker.
+		
+	<p>If you plan on using a remote PostgreSQL DBMS Server,
+	than you will need to have the PostgreSQL client software on your
+	local computer that includes libpq.so (pq.dll on Windows).
+	
+	<p>The System.Data tests use this connection string to connect
+	to the PostgreSQL database named "test" at host "localhost" as
+	user "postgres".
+
+<pre>
+"host=localhost;dbname=test;user=postgres"
+</pre>
+		
+	<p>Installation instructions for PostgreSQL DBMS:
+
+	<b>On Unix</b>
+
+	<ul>
+		* Read the PostgreSQL Installation Instructions 
+		at \usr\doc\postgresql-x.x.x\html\installation.html
+		
+		* Depending on your Unix system, 
+		PostgreSQL maybe already installed, a database user 'postgres' created, 
+		a linux user 'postgres' created and initdb ran.  Or maybe not.
+
+<pre>
+ su

+ adduser postgres

+ mkdir /usr/local/pgsql/data

+ chown postgres /usr/local/pgsql/data

+ su - postgres

+ initdb -D /usr/local/pgsql/data

+ postmaster -i -D /usr/local/pgsql/data

+ createdb test

+ psql test
+</pre>
+	
+		* Make sure you have a database user named postgres.  It is best to install
+		the PostgreSQL DBMS under linux user postgres.  When you run the postmaster,
+		run it under the user postgres as well.  If this was not done, then you
+		will need to create a user named postgres for the System.Data tests.
+
+		* If you already installed PostgeSQL and you do not have a database
+		user named postgres, then you can create user postgres using psql:
+		
+<pre>		
+psql test
+create user postgres with password 'fun2db';
+</pre>
+				
+		* The postmaster must be run with -i option.
+		
+		* In the /usr/local/pgsql/data/pg_hba.conf file, you need
+		to have the AUTH_TYPE set to md5.  You can read more on this at
+		/usr/doc/postgresql-7.2.1/html/client-authentication.html 
+		or wherever your
+		PostgreSQL html docs are located.  See the 2nd line below,
+		host 127.0.0.1 has an AUTH_TYPE md5 in pg_hba.conf.
+		
+<pre>
+ # TYPE     DATABASE    IP_ADDRESS    MASK               AUTH_TYPE
+
+ local      all                                          trust
+ host       all         127.0.0.1     255.255.255.255    md5
+</pre>
+
+	* If you can not find your PostgreSQL documentation locally or you 
+	did not install it, then you 
+	can get it <a href="http://www.postgresql.org/idocs/">here</a>.
+
+	</ul>
+
+	<b>On Windows</b>
+
+	<ul>
+		* Use the <a href="http://www.cygwin.com/">Cygwin</a> installer to 
+		  install the PostgreSQL DBMS.  It is
+		  found in the database category.
+		  
+		* <p>Read the file postgres-x.x.README at /usr/doc/Cygwin and read 
+		  the requirements to install PostgreSQL.  Those requirements
+		  are included with cygwin except cygipc.  A default installtion
+		  of cygwin does not install everything you will need, so on the 
+		  safe side, just include everything when installing cygwin.
+		
+		* <p>The -x.x in postgres-x.x is the version of your PostgreSQL DBMS.
+		
+		* <p>Once Cygwin has installed the PostgreSQL DBMS on your computer,
+		  read the file FAQ_MSWIN which is available 
+		  in /usr/doc/postgres-x.x 
+				  
+		* <p>Important notes from this file are:
+		  
+		  <ul>
+				<p><b>2.</b> - Install the latest <a href="http://www.neuro.gatech.edu/users/cwilson/cygutils/OBSOLETE/V1.1/cygipc/index.html">CygIPC</a> package.
+			  			  
+				<p>The cygipc package contains the ipc-daemon you will need 
+				to run before you can
+				run the PostgreSQL DBMS Server daemon (postmaster) or run
+				initdb which initializes the PostgreSQL database.
+			  
+				<p><b>3.</b>  The Cygwin bin directory has to be placed in 
+				the path before the Windows program directories, 
+				for example, C:\cygwin\bin 
+			  
+				<p><b>My own note.</b>  In the Windows control panel, I set
+				the environment variables PATH to my cygwin /usr/local/bin,
+				/usr/bin, and /bin.  I also set my LD_LIBRARY_PATH to 
+				/usr/local/lib and /usr/lib.  For example:

+				package.  There
+				are two ways to do this: run it from the command line as:
+			  
+				<p>
+<pre>
+ipc-daemon &
+</pre> 			  
+				<p>or you can set it up as a Windows service.  See the 
+				file cygrunsrv.README at /usr/doc/Cygwin on how to do this
+				for ipc-daemon and postmaster.  Note the
+				troubleshooting section at the end of 
+				the cygrunsrv.README file.
+			  
+				<p>To install ipc-daemon as a service, 
+				you just have to run
+			  
+				<p>
+<pre>
+ipc-daemon --install-as-service' (--remove-as-service) 
+</pre>
+			  
+				<p>and then run
+

+			  
+			<p>Read the installation.html file 
+			at /usr/doc/postgresql-x.x/html/installation.html
+		
+			<p>You will see in this file that you will need to 
+			run the following commands:
+		  
+			<p>
+<pre>
+mkdir /usr/local/pgsql/data

+initdb -D /usr/local/pgsql/data

+postmaster -D /usr/local/pgsql/data

+createdb test

+psql test  		
+</pre>
+		  
+			<p>When you need to connect to the database, 
+			you will need ipc-daemon and postmaster running.  Start ipc-daemon
+			before any of the command above.  If you restart your computer, you
+			need to start ipc-daemon and postmaster either manually or as a 
+			service.
+		  
+			<p>psql is a command-line PostgreSQL client tool to 
+			enter and run SQL commands and queries.
+		  
+			<p>If there is no database user named postgres, create a user named
+			postgres with the following SQL command in the client tool psql:
+		  
+			<p>
+<pre>
+psql test
+create user postgres with password 'fun2db';
+</pre>
+			<p>The only reason I say this is so you can easily use the System.Data tests
+			without having to change the database, userid, etc.
+	</ul>
+	
+	<p>In the path mcs/class/System.Data/Test
+	there is a PostgreSQL test program named
+	PostgreTest.cs.  Thanks goes to Gonzalo for creating the original
+	PostgreSQL test.
+	
+	<p>To use it to test System.Data, you
+	modify the file to your PostgreSQL database
+	connection requirements:
+
+	<p>
+	<ul>
+		<li><b>dbname</b> database, ie., test</li>
+		<li><b>host</b> hostname of the PostgreSQL DBMS Server to connect to, ie., localhost</li>
+		<li><b>user</b> username, ie., someuser</li>
+		<li><b>password</b> password, ie., mypass1234</li>
+	</ul>
+	
+	<p>The connection string is in OLE-DB connection string format.  Internally,
+	SqlConnection converts this to the PostgreSQL connection string format.
+	
+	<p>
+<pre>
+    OLE-DB: "host=localhost;dbname=test;user=joe;password=smoe"
+PostgreSQL: "host=localhost dbname=test user=joe password=smoe"
+</pre>
+
+	<p>
+	Note that OLE-DB includes the semicolons while PostgreSQL's connection
+	string does not.
+
+	<p>
+    To compile the PostgresTest.cs program, do:
+    
+    <p>
+<pre>
+mcs PostgresTest.cs -r System.Data.dll
+</pre>
+    
+    <p>
+    To run using mint, do:

+
+	Sources are currently being updated every hour.
+
+** Checking out the sources
+
+	To check out the sources for the first time from the

+
+<pre>
+	export CVSROOT=:pserver:anonymous@anoncvs.go-mono.com:/mono
+	cvs login
+	cvs -z3 co mcs mono gtk-sharp
+</pre>
+
+	That will get you the compiler and class libraries (mcs), the
+	interpreter and JITer (mono) and the Gtk# bindings.
+
+	The server is located in Spain.
+
+** Updating the sources
+
+	To update your sources every day, you use this command:

+* ASP.NET
+
+	ASP.NET support is divided in two pieces:
+	<ul>
+		* Web Forms (Web Applications infrastructure).
+
+		* Web Services (the SOAP-based rpc system).
+	</ul>
+
+	There is work underway for both systems.  The Web Forms
+	support is more advanced at this point, and various ".aspx"
+	programs can be run using the Mono runtime and the XSP page
+	parser.
+
+	Tim started work on the Web Services early this week.
+	Although we have a SoapFormatter as part of the remoting
+	infrastructure already (contributed by Jesus), most people
+	will be using the ASP.NET Web-services support.  Work for the
+	supporting class libraries just started recently.
+
+* Web Forms: The pieces
+
+	There are a couple of components to the puzzle:
+
+	<ul>
+		* .aspx page parser (converts .aspx to C# code).
+	
+		* System.Web.HttpRuntime support.
+	
+		* Web controls (System.Web.UI.HtmlControls and
+		  System.Web.UI.WebControls).
+	
+		* Underlying infrastructure for the controls (System.Web.UI).
+	
+		* HttpRuntime.ProcessRequest is the core of the ASP.NET
+		  implementation.
+	</ul>
+
+
+	Gonzalo has been working on an ASP.NET parser that takes .aspx
+	files and generated the code required to run them (the code lives in
+	module `xsp' along with a little web server for testing).
+
+	Most of the runtime support was mostly written by Patrik Torstensson
+	(now at Intel).  This was interesting, because in order to implement
+	some of its features, Patrik had to go into the runtime/JIT engine and
+	he spent a few weeks doing work there.
+
+	The classes for running ASP.NET are being actively written.
+	Gaurav, Leen and Patrik worked in the core of the classes
+	required to run ASP.NET web application as well as a small
+	embeddable web server.
+
+	Duncan got our System.Web assembly to compile.
+
+** HttpRuntime
+
+	Patrik has authored most of the HttpRuntime support (both on
+	the System.Web and on the foundation) but it is still not
+	ready to run.
+
+** XSP
+
+	Currently XSP provides the .aspx compiler to C#.  It would be
+	interesting to see if it makes sense to extend the ASP.NET
+	syntax to make it simpler to develop applications.
+
+	Gonzalo is in charge of the compiler.
+
+** Controls
+
+	A lot of work has been put in the various classes that
+	implement the controls (UI.HtmlControls and UI.WebControls),
+	but they have been coded mostly in the dark, and without being
+	able to test them in real life: Gaurav and Leen worked very
+	hard on this namespace, but needs to be finished.
+
+	We can now render all HtmlControls and some WebControls. Work is
+	ongoing to make all WebControls render HTML.
+
+** Extending ASP.NET
+
+	Currently you have to reference in your ASP.NET the control
+	and all of its properties, which works fine if you have a GUI
+	designer, but is harder for people used to develop using text
+	editors.
+
+	Since we have a parser, we could extend this parser to allow
+	people to still use ASP.NET controls, using a simpler syntax.
+	For example people doing blogs and editing their templates
+	over the web probably do not want to use direct ASP.NET but a
+	wrapper around it.
+
+** Roadmap
+
+        1. The Parser.
+
+        2. Get the parser to generate output compatible with ASP.NET.
+
+        3. Run the sample output with the real Microsoft runtime
+           but using our generated page.   
+
+        4. Run the sample with our classes with the .NET runtime.
+	<b>We are here</b>.
+
+        5. Finish HttpRuntime.
+	
+        6. Running our sample code with our classes with our runtime.
+
+** How to Help
+
+        Currently we are testing and fixing HtmlControls, WebControls and
+        validators.
+
+        In the CVS module XSP you can find the aspx to C# page parser,
+        a little web server used for testing and a directory containing
+        sample aspx pages.
+
+        You have some documentation under doc directory and in the README
+        file of each directory. They explain how to test our System.Web.
+        Testing is really easy!

+* MCS: The Ximian C# compiler
+
+	MCS is currently able to compile itself and many more C#
+	programs (there is a test suite included that you can use).
+
+	We are in feature completion mode right now.  There are still
+	a couple of areas that are not covered by the Mono compiler, but
+	they are very very few at this point.
+
+	MCS was able to parse itself on April 2001, MCS compiled itself
+	for the first time on December 28 2001.  MCS became self hosting
+	on January 3rd, 2002. 
+
+	The Mono Runtime and the Mono execution engine were able to make
+	our compiler self hosting on March 12, 2002.
+
+	A test suite is maintained to track the progress of
+	the compiler and various programs are routinely compiled and
+	ran.
+
+** Obtaining MCS
+
+	The Mono C# compiler is part of the `mcs' module in the Mono CVS
+	you can get it from our <a href="anoncvs.html">Anonymous CVS</a> server,
+	or you can get nightly <a href="download.html">download page</a>.
+
+** Running MCS
+
+	MCS is written in C# and uses heavily the .NET APIs.  MCS runs
+	on Linux (with the Mono runtime) and Windows (with the .NET
+	framework runtime)
+
+** Reporting Bugs in MCS
+
+	When you report a bug, try to provide a small test case that would
+	show the error so we can include this as part of the Mono C# regression
+	test suite.
+
+	If the bug is an error or a warning that we do not flag, write
+	a sample program called `csXXXX.cs' where XXXX is the code number
+	that is used by the Microsoft C# compiler that illustrates the 
+	problem.  That way we can also do regression tests on the invalid
+	input.  
+
+** Phases of the compiler
+
+	The compiler has a number of phases:
+
+	<ul>
+		* Lexical analyzer: hand-coded lexical analyzer that
+		  provides tokens to the parser.
+
+		* The Parser: the parser is implemented using Jay (A
+		  Berkeley Yacc port to Java, that I ported to C#).
+		  The parser does minimal work and syntax checking,
+		  and only constructs a parsed tree.
+
+		  Each language element gets its own class.  The code
+		  convention is to use an uppercase name for the
+		  language element.  So a C# class and its associated
+		  information is kept in a "Class" class, a "struct"
+		  in a "Struct" class and so on.  Statements derive
+		  from the "Statement" class, and Expressions from the
+		  Expr class.
+
+		* Parent class resolution: before the actual code
+		  generation, we need to resolve the parents and
+		  interfaces for interface, classe and struct
+		  definitions.
+
+		* Semantic analysis: since C# can not resolve in a
+		  top-down pass what identifiers actually mean, we
+		  have to postpone this decision until the above steps
+		  are finished.
+
+		* Code generation: The code generation is done through
+		  the System.Reflection.Emit API.
+	</ul>
+
+** CIL Optimizations.
+
+	The compiler performs a number of simple optimizations on its input:
+	constant folding (this is required by the C# language spec) and 
+	can perform dead code elimination.
+
+	Other more interesting optimizations like hoisting are not possible
+	at this point since the compiler output at this point does not
+	generate an intermediate representation that is suitable to
+	perform basic block computation.  
+
+	Adding an intermediate layer to enable the basic block
+	computation to the compiler should be a simple task, but we
+	are considering having a generic CIL optimizer.  Since all the
+	information that is required to perform basic block-based
+	optimizations is available at the CIL level, we might just skip
+	this step altogether and have just a generic IL optimizer that
+	would perform hoisting on arbitrary CIL programs, not only
+	those produced by MCS.  
+
+	If this tool is further expanded to perform constant folding
+	(not needed for our C# compiler, as it is already in there)
+	and dead code elimination, other compiler authors might be
+	able to use this generic CIL optimizer in their projects
+	reducing their time to develop a production compiler. 
+
+<a name="tasks">
+** Current pending tasks
+
+	Simple tasks:
+
+	<ul>
+		* Redo the way we deal with built-in operators.
+	</ul>
+
+	Larger tasks:
+	<ul>
+
+		* Jay does not work correctly with `error'
+		  productions, making parser errors hard to point.  It
+		  would be best to port the Bison-To-Java compiler to
+		  become Bison-to-C# compiler. 
+		  
+		  Nick Drochak has started a project on SourceForge for this.
+		  You can find the project at: <a href="http://sourceforge.net/projects/jb2csharp/">
+		  http://sourceforge.net/projects/jb2csharp/</a>
+
+		* Semantic Analysis: Return path coverage and
+		  initialization before use coverage are two great
+		  features of C# that help reduce the number of bugs
+		  in applications.  It is one interesting hack.
+
+	</ul>
+
+** Questions and Answers
+
+Q: Why not write a C# front-end for GCC?
+
+A: I wanted to learn about C#, and this was an exercise in this
+   task.  The resulting compiler is highly object-oriented, which has
+   lead to a very nice, easy to follow and simple implementation of
+   the compiler.
+
+   I found that the design of this compiler is very similar to
+   Guavac's implementation.
+
+   Targeting the CIL/MSIL byte codes would require to re-architecting
+   GCC, as GCC is mostly designed to be used for register machines.
+   
+   The GCC Java engine that generates Java byte codes cheats: it does
+   not use the GCC backend; it has a special backend just for Java, so
+   you can not really generate Java bytecodes from the other languages
+   supported by GCC. 
+
+Q: If your C# compiler is written in C#, how do you plan on getting
+   this working on a non-Microsoft environment.
+
+   We will do this through an implementation of the CLI Virtual
+   Execution System for Unix (our JIT engine). 
+
+   Our JIT engine is working for the purposes of using the compiler.
+   The supporting class libraries are being worked on to fully support
+   the compiler.
+
+Q: Do you use Bison?
+
+A: No, currently I am using Jay which is a port of Berkeley Yacc to
+   Java that I later ported to C#.  This means that error recovery is
+   not as nice as I would like to, and for some reason error
+   productions are not being caught.  
+
+   In the future I want to port one of the Bison/Java ports to C# for
+   the parser.
+
+Q: Should someone work on a GCC front-end to C#?
+
+A: I would love if someone does, and we would love to help anyone that
+   takes on that task, but we do not have the time or expertise to
+   build a C# compiler with the GCC engine.  I find it a lot more fun
+   personally to work on C# on a C# compiler, which has an intrinsic
+   beauty.
+
+   We can provide help and assistance to anyone who would like to work
+   on this task.
+
+Q: Should someone make a GCC backend that will generate CIL images?
+
+A: I would love to see a backend to GCC that generates CIL images.  It
+   would provide a ton of free compilers that would generate CIL
+   code.  This is something that people would want to look into
+   anyways for Windows interoperation in the future.
+
+   Again, we would love to provide help and assistance to anyone
+   interested in working in such a project.
+
+Q: What about making a front-end to GCC that takes CIL images and
+   generates native code?
+
+A: I would love to see this, specially since GCC supports this same
+   feature for Java Byte Codes.  You could use the metadata library
+   from Mono to read the byte codes (ie, this would be your
+   "front-end") and generate the trees that get passed to the
+   optimizer.
+
+   Ideally our implementation of the CLI will be available as a shared
+   library that could be linked with your application as its runtime
+   support. 
+
+   Again, we would love to provide help and assistance to anyone
+   interested in working in such a project.
+   
+Q: But would this work around the GPL in the GCC compiler and allow
+   people to work on non-free front-ends?
+
+A: People can already do this by targeting the JVM byte codes (there
+   are about 130 compilers for various languages that target the JVM).
+
+Q: Why are you writing a JIT engine instead of a front-end to GCC?
+
+A: The JIT engine and runtime engine will be able to execute CIL
+   executables generated on Windows.

+* CVS Access
+
+	If you are an active Mono developer, you can get a CVS account
+	that hosts the Mono source code.  
+
+	If you are not a developer, but want to track the development, please
+	see the <a href="anoncvs.html">AnonCVS</a> instructions.
+
+	Send an e-mail to miguel with your public SSH key for this
+	purpose.  Please specify if the key was generated with SSH1 or SSH2.
+
+	If you are using SSH2, please generate your key using:
+
+<pre>
+	ssh-keygen -t rsa
+</pre>
+
+	And mail me the id_rsa.pub file.
+
+	If you are using SSH1, run:
+<pre>
+	ssh-keygen
+</pre>
+
+	And mail me your identity.pub file.
+
+	You will need CVS and SSH.  Windows users can get both by
+	installing Cygwin (<a
+	href="http://www.cygwin.com">http://www.cygwin.com</a>)
+
+	Unix users will probably have those tools installed already.
+
+** Checking out the sources
+
+	To check out the sources for the first time from the
+	repository, use this command:
+
+<pre>
+	export CVS_RSH=ssh
+	export CVSROOT=username@mono-cvs.ximian.com:/cvs/public
+	cvs -z3 co mcs mono
+</pre>
+
+** Updating your sources
+
+	Every day people will be making changes, to get your latest
+	updated sources, use:
+
+<pre>
+	cvs -z3 update -Pd mcs mono
+</pre>
+
+	Note: The '-z3' enables compression for the whole cvs action.
+	The '-Pd' makes the update operation (P)rune directories that
+	have been deleted and get new (d)irectories added to the
+	repository.
+
+** Making patches
+
+	Usually you will want to make a patch to contribute, and let
+	other people review it before commiting it.  To obtain such a
+	"patch", you type:
+	
+<pre>
+	cd directory-you-want-to-diff
+	cvs -z3 diff -u > file.diff
+	mail mono-list@ximian.com < file.diff
+</pre>
+
+** Keeping track of changes.
+
+	We provide two e-mail based mechanisms to keep track of
+	changes to the code base:
+	
+	<ul>
+		* <a href="mailto:mono-patches-request@ximian.com">
+		  mono-patches@ximian.com</a>: This mailing list receives
+		  in patch form all the changes that are being made to the
+		  CVS.
+
+		* <a href="mailto:mono-cvs-list-request@ximian.com">
+		  mono-cvs-list@ximian.com</a>: This mailing list only
+		  receives the CVS commit logs with a list of files
+		  modified.
+	</ul>
+
+	We hope to offer LXR and Bonsai in the future as well.
+
+** Commiting your work
+
+	Once you get approval to commit to the CVS, or if you are
+	commiting code that you are the maintainer of, you will want
+	to commit your code to CVS. 
+
+	To do this, you have to "add" any new files that you created:
+
+<pre>
+	cvs add new-file.cs
+</pre>
+
+	And then commit your changes to the repository:
+
+<pre>
+	cvs commit file-1.cs file-2.cs
+</pre>
+
+** The Mailing List
+
+	To keep track of the various development and changes to the
+	CVS tree, you can subscribe to the mono-cvs-list@ximian.com.
+	To subscribe, send an email message to
+	mono-cvs-list-request@ximian.com and in the body of the
+	message put `subscribe'.
+
+	This will send you an email message every time a change is
+	made to the CVS repository, together with the information that
+	the author of the changes submitted.
+	
+** Recommendations
+
+	Please do not commit code that would break the compile to the
+	CVS, because that normally wastes everybody's time.  Two things 
+	are important in this step: trying to build your sources and making 
+	sure that you add all the new files before you do a commit.
+
+	To build the sources, most of the type trying the `make' command
+	is enough.  In some cases (the class libraries) we use nant, so
+	you need to run nant manually.
+
+	Use ChangeLog entries so we can keep textual descriptions of
+	your work, and use the contents of your ChangeLog file as the
+	CVS commit message (ie, paste the contents of this into the
+	editor buffer).
+
+	If you are making changes to someone else's code, please make
+	sure you get in touch with the maintainer of that code before
+	applying patches.  You want to avoid commiting conflicting
+	work to someone else's code.

+* The Class Library
+
+	The Class Library should be compatible with Microsoft's .NET
+	implementation.
+
+	Please see the <a href="class-status.html">Class Status</a>
+	page for a status of who is working on which classes.
+	
+	We will write as much code as possible in C#. We may need to
+	interface with code written in C to gain access to the
+	functionality of libraries like libart, Gtk+, and libc.
+
+** Contributing
+
+	We welcome contributions to the the Class Library.  To get
+	started, check the status page for information about which
+	APIs are being worked on, and how to get in touch with 
+	individual maintainers.  
+
+	If you want to work on a class, first check the <a
+	href="download.html">Classes Distribution</a> to see if it is
+	not implemented yet, if not, check the <a
+	href="class-status.html">Class Status</a> to see if someone is
+	already working on it, and maybe contact them.
+
+	If nobody is working on it, mail <a
+	href="mailto:mono-list@ximian.com">mono-list@ximian.com</a>
+   	with the class you want to implement and CC <a

+
+	You can also track live the activities of the Mono CVS module
+	by subscribing to the <a
+	href="http://lists.ximian.com/mailman/listinfo/mono-cvs-list">mono-cvs-list</a>
+
+
+** Missing features
+
+	Our class libraries miss some features, for example, most classes
+	do not implement the serialization bits at all, it would be a good
+	contribution to add this to each class.
+
+	This is a simple task, but it needs to be done in a compatible way
+	with the Microsoft.NET classes: using the same arguments to serialize
+	and reincarnate data.
+
+** Layout
+
+	The Class Library resides in the `mcs' module in the directoy
+	`class'.
+	
+	Each directory in the directory represents the assembly where
+	the code belongs to, and inside each directory we divide the
+	code based on the namespace they implement.
+
+	There are two cases when we should consider portability: when
+	we are dealing with a couple of classes only that differ from
+	system to system (Consider System.Net and System.IO for Win32
+	and Unix).  In those cases we will just place the files for
+	example on <t>corlib/System/System.IO/Unix-Console.cs</t> and
+	<t>corlib/System/System.IO/Win32-Console.cs</t>.
+
+	For classes that might differ more (for example, the
+	implementation of Windows.Forms), we might have different
+	directories altogether: <t>System.Windows.Forms/Win32</t>,
+	<t>System.Windows.Forms/Gtk+</t> and
+	<t>System.Windows.Forms/Cocoa</t>.
+
+** Using existing components from GNOME.
+
+	Our current plan is to implement the GUI tools on top of
+	Gtk+.  The only obstacle here is that applications from Windows
+	might expect to be able to pull the HWND property from the
+	widgets and use PInvoke to call Windows functions.
+
+** Class Library and Win32 dependencies.
+
+	There are a few spots where the Win32 foundation is exposed to
+	the class library (for example, the HDC and HWND properties in
+	the GDI+). Casual inspection suggests that these can be
+	safely mapped to Gdk's GC and GdkWindow pointers without
+	breaking anything.
+
+	The only drawback is that support for PInvoke of Win32 code
+	won't be available.  An alternate solution would be to use
+	portions of Wine, or even to use Wine as our toolkit.
+
+*** Initial GDI+ and WinForms implementation
+
+	The initial implementation will use Gtk+ as the underlying
+ 	toolkit. Since GTK+ has already been ported to many windowing
+	systems other than X (including frame buffer, Win32, and BeOS)
+	its use should cover most applications for most users. 
+	
+*** Database access
+
+	We will implement ADO.NET functionality by reusing <a
+	href="http://www.gnome-db.org">GNOME-DB</a>. This is an ideal
+	choice, since GNOME-DB was implemented precisely to provide an
+	ADO-like system for GNOME.
+
+*** Component Integration
+
+	We will provide a new namespace to use GNOME specific features
+	as well as a namespace to host Bonobo interfaces and classes
+	in Mono.  
+
+** Licensing
+
+	The class library is being licensed under the terms of the 
+	<a
+	href="http://www.opensource.org/licenses/mit-license.html">MIT
+	license.</a>  This is the same license used by the X11 window
+	system.
+
+** Class Library testing
+
+	We need to write regression tests that will verify
+	the correctness of the class library, compiler, and JIT
+	engine.
+
+	Please write your regression tests using <a
+	href="http://nunit.sourceforge.net">NUnit</a>
+
+** Coding conventions
+
+	Please follow the conventions on the ECMA specification (On
+	the Annex Partition) for your coding your libraries. 
+
+	Use 8 space tabs for writing your code (hopefully we can keep
+	this consistent).  If you are modifying someone else's code, try
+	to keep the coding style similar.
+
+	For a rationale on 8 space tabs, read Linus Torvald's Coding
+	Style guidelines in the Linux kernel source for a rationale. 
+
+*** Missing implementation bits
+
+	If you implement a class and you are missing implementation bits,
+	please put in the code the word "TODO" and a description of what
+	is missing to be implemented.
+
+*** Tagging buggy code
+
+	If there is a bug in your implementation tag the problem by using
+	the word "FIXME" in the code, together with a description of the 
+	problem.
+
+	Do not use XXX or obscure descriptions, because otherwise people
+	will not be able to understand what you mean.
+
+*** Tagging Lame specs
+
+	Sometimes the specification will be lame (consider Version.ToString (fieldCount)
+	where there is no way of knowing how many fields are available, making the API
+	not only stupid, but leading to unreliable code).
+
+	In those cases, use the keyword "LAMESPEC".
+
+** Namespaces
+
+	We are using a number of namespaces in the class libraries for
+	private classes when we need them, you are encouraged to use these:
+
+<pre>
+Mono
+ .Languages     // General Compiler classes
+   .CSharp      // Specific C# parsing/tokenizing classes
+   .MonoBASIC   // Specific VB.NET/MonoBASIC parsing/tokenizing classes
+   .Python      // Specific Python parsing/tokenizing classes
+ .Runtime
+   .LateBind    // General latebinding-support for MonoBASIC/Python
+   .MonoBASIC   // Specific runtime classes for MonoBASIC programs
+   .Python      // Specific runtime classes for Python programs
+ .Web
+   .UI
+     .Utils     // Gaurav utility classes
+</pre>
+
+** FAQ
+
+Frequently asked questions about the class library:
+
+Q: I am writing a new class that overrides one of the system classes,
+   and I am getting a 1595 warning from the compiler.  Should we use a
+   different namespace?
+
+A: There is a quick solution to the problem, you can pass the command
+   line argument /nowarn:1595 and this will effectively let you use
+   your implementation of the code, while overriding the ones from the
+   system assemblies.

+* Class Library Documentation
+
+** Summary
+
+	<em>
+	[This documentation is in progress.  Comments to
+	<a href="mailto:jbarn@httcb.net">jbarn@httcb.net</a>.]
+	</em>
+	
+	While using inline XML tags to document classes is certainly
+	convenient, properly verbose documentation quickly overwhelms
+	the code, making the source quite difficult to read.  Furthermore,
+	multilingual documentation makes for significant additional text.
+	
+	With these considerations in mind, Mono will use external XML files
+	for type documentation, rather than documenting the source inline.
+	
+	Several tools will be created for managing, verifying, generating,
+	and updating class library documentation, including:
+	
+	<ul>
+		<li><a href="#docstub">docstub</a></li>
+		<li><a href="#docverify">docverify</a></li>
+		<li><a href="#docconv">docconv</a></li>
+		<li><a href="#docgen">docgen</a></li>
+		<li><a href="#monodoc">monodoc</a></li>
+	</ul>
+	
+** XML Documentation Files and Formats
+
+	
+*** Monodoc XML
+	This XML is similar to the XML documentation described in the
+	C# standard, with added tags for internationalization and a
+	slightly different structure.  Documentation and a DTD/Schema
+	for Monodoc XML is forthcoming.
+	
+	Monodoc XML does not contain any definitive type information,
+	and is only useful in conjunction with the Type definition for
+	whatever is being documented.
+	
+	This XML could be generated by hand, by monostub, or by monodoc.
+	
+*** Assembly XML
+	This XML is generated by combining runtime type information for
+	an Assembly with a collection of Monodoc XML files.  The resultant
+	XML (in the best of cases) contains both complete type and
+	documentary information for each type in the assembly.
+	
+	This XML contains enough information to be transformed into
+	user-accessible documentation.  It is likely that scripts
+	will be created to generate reference docs as HTML and other
+	formats.
+	
+	Documentation and a DTD/Schema for Assembly XML is forthcoming.
+	
+** Documentation Tools
+
+*** <a name="docstub">docstub</a>
+	Given a type name and an assembly, generates stub Monodoc XML
+	documentation for the type.  Optionally, docstub can attempt to
+	populate initial documentation from an XML file in the format
+	published along with the ECMA standard.
+	
+*** <a name="docverify">docverify</a>
+	Given a Monodoc XML file and an assembly, verifies that the
+	documentation matches the compiled type.  Checks signatures,
+	parameters, et cetera.
+	
+*** <a name="docconv">docconv</a>
+	Converts from Monodoc XML to the standard C# compiler-emitted
+	XML format and vice versa.
+	
+*** <a name="docgen">docgen</a>
+	Given an assembly and a collection of Monodoc XML files, creates
+	an Assembly XML file containing all documentation and type information
+	available.  This output is suitable for transforming into user
+	documentation.
+	
+*** <a name="monodoc">monodoc</a>
+	A GUI tool for documentation and translation, this encapsulates
+	the capabilities of docstub, docverify, docconv, and docgen in
+	a friendly user interface.  In addition, monodoc provides features
+	to ease translation, such as side-by-side editing and coverage
+	statistics.
+	
+** Status and Roadmap
+
+*** 2 January 2002
+
+	As I write the initial version of this document, very little has been
+	implemented.  Currently, there is a:
+	
+	<ul>
+	<li>Preliminary version of the Monodoc XML format</li>
+	<li>Preliminary version of the docstub utility</li>
+	</ul>
+	
+	Here's hoping for frequent, productive updates.
+
+** Get Involved

+* Contributing to the Mono project
+
+	There are many ways in which you can help in the Mono project:
+
+	<ul>
+		* <b>Programmers:</b> You can work on a free
+		  implementation of the <a
+		  href="class-library.html">class libraries</a>, the
+		  <a href="runtime.html">runtime engine</a>, <a
+		  href="tools.html">the tools</a>, the <a

+	</ul>
+
+	Those are just broad things that need to be worked on, but
+	something that would help tremendously would be to help with
+	small duties in the project that need to be addressed. 
+
+	You can see what needs to be done in the class libraries <a href="class-status.html">here</a>
+
+* IRC Channel
+
+	Many developers get together on the <b>#mono</b> irc channel
+	on the <b>irc.gnome.org</b> server.  
+
+** To start contributing
+
+	As a programmer, you can contribute in three different scenarios to Mono:
+
+	<ul>
+		* If you only have Linux/Unix.
+		* If you only have Windows.
+
+		* If you have both Linux and Windows.
+	</ul>
+
+	You might also want to check our <a href="#setup">common
+	setups</a> section that describes some common setups that people
+	use while working on Mono.
+
+*** Contributing to the class library, regression tests or the compiler
+
+	This only requires Windows currently.
+
+	To start developing classes or to contribute to the compiler,
+	you only need Windows and the .NET Framework 1.0 SDK.  Please notice
+	that you do not need Visual Studio (although you can use it if
+	you want).  The .NET Framework SDK requires some version of
+	Windows XP or Windows NT.  If you are running Windows 98, 95
+	or Me, you could use instead the <a
+	href="http://msdn.microsoft.com/downloads/default.asp?url=/downloads/sample.asp?url=/msdn-files/027/001/829/msdncompositedoc.xml">.NET Redist package</a>, but it
+	lacks the documentation browser and the ildasm program (C#, VB, JScript and IL 
+	assembler are included).
+
+	You can get it <a href="http://msdn.microsoft.com/downloads/default.asp?url=/downloads/sample.asp?url=/msdn-files/027/000/976/msdncompositedoc.xml&frame=true">here</a>
+
+	If you are new to .NET, writing regression tests is a good way
+	of starting to contribute: it will help you get used to C# as
+	well as getting comfortable with the .NET APIs.  
+
+	This helps because at this point you might be the best
+	qualified person to fix a problem found by the regression
+	test, or you might have a new class to implement in the .NET
+	world that only has a test suite.  
+	
+	To get started writing tests see the <a href="testing.html">Test Suite</a>
+	section. <a href="mono-contribution-howto.html">Here</a> there is a good All-In-One introduction to the art of writing tests.
+
+
+*** Contributing to the runtime engine
+
+	This only requires Linux, currently some tasks are easier if you
+	have access to Windows as well.
+
+	Here are a few things you can do:
+	<ul>
+		* Port the runtime to other architectures.
+		* Port the runtime to other operating systems.
+		* Finish the IL code verifier in the runtime.
+		* Hack the JIT, improve the code generator, add new
+		  pattern rules, improve the register allocator.
+		* Implement the debugging interfaaces
+	</ul>
+
+** Bug reporting
+
+	If you find bugs in Mono, please make sure you enter a bug
+	report so we can keep track of problems in Mono.
+

+
+		* Adding serialization support to all the classes.
+
+		  We have many classes, but we have not implemented in

+* Common Setups
+
+	People running both Linux and Windows while contributing to
+	Mono use a number of tricks to increase their productivity.
+
+	Scenarios:
+
+	<ul>
+		* <b>Linux host and Windows host</b>
+
+		  The Windows file system is shared (right click on
+		  your hard drive icon, and select sharing, allow this
+		  to be shared).  
+
+		  The Windows machine has the required build tools
+		  (cygwin, and the .NET framework).  On the Windows
+		  machine, you want to setup the ssh server (run the
+		  ssh-host-config program to configure your ssh) and
+		  run it (from a cygwin terminal, type: /usr/sbin/sshd).
+
+		  From the Linux side, you want to mount the Windows
+		  file system, using something like this:
+
+<tt><pre>
+	mount -t smbfs -o uid=miguel,username="Miguel de Icaza" "//quack/c$" /mnt
+</pre></tt>
+
+		  In the above example, my Linux user name is
+		  `miguel', and this will allow this user to have
+		  read/write access to the share.  
+
+		  The host name is `quack', and the name of the share
+		  is `c$' (that is the C: partition).  
+
+		  The file system is accessible on /mnt.
+
+		  You can perform your cvs update and cvs commits from
+		  the /mnt directory, and run Emacs or your favorite
+		  Linux text editor on the Unix side in this way.
+
+		  Then from another terminal, you can ssh into your
+		  Windows box using ssh, like this: ssh "Miguel de Icaza@quack"
+	</ul>
+
+* Special Note
+
+	If you have looked at Microsoft's implementation of .NET or
+	their shared source code, you may not be able to contribute
+	to Mono.  Details will follow when we know more about this.
+
+	In general be careful when you are implementing free software
+	and you have access to proprietary code.  We need to make sure
+	that we are not using someone else's copyrighted code
+	accidentally. 
+
+	Please do not use the <b>ildasm</b> program to disassemble
+	proprietary code when you are planning to reimplement a class
+	for Mono.  If you have done this, we might not be able to use
+	your code.
+
+	Please stick to published documentation for implementing any
+	classes.

+* Developer FAQ
+
+** New classes
+
+Q: Should we write classes which are not part of the .NET or ECMA specs?
+
+A: Yes.  The ECMA and .NET specifications are far from complete, and
+   to produce a complete platform we will need a number of other
+   classes and components.
+
+   Any new classes that are not part of .NET or ECMA should be
+   designed to be reusable on anyone's CLI implementation.  So that
+   Windows developers can also use any new classes that we come up
+   with.
+
+   We have a few existing <a href="ideas.html">Ideas on missing
+   classes</a> 
+
+** Language Compatibility
+
+Q: What is the magic that allow multiple languages to co-exist?
+
+A: From Fergus Henderson:
+
+<i><blockquote>
+There are different levels of interoperability.
+The ECMA spec defines different categories of
+CLS (Common Language Specification) conformance.
+There are also some useful categories that don't
+correspond to any of the levels defined in the ECMA spec.
+In increasing degree of difficulty, your language implementation
+can
+
+	<ul>
+	* (a) just generate IL
+
+	* (b) be a CLS "consumer", which means that it can read in
+	  meta-data describing component interfaces,
+	  and that it provides a way to declare variables of
+	  CLS-complaint types and to call CLS-complaint methods.
+
+	* (c) be a CLS "extender", which means that it can in addition
+	  derive from CLS-compliant classes
+	  and implement CLS-compliant interfaces
+
+	* (d) be able to produce components with *any* CLS-compliant
+	component interface.
+	</ul>
+
+Supporting some of these may require extending your language.  However,
+you can get quite a lot of interoperability by just putting appropriate
+functionality in your compiler, without extending your language.
+
+For some things, e.g. ASP.NET, your language implementation also needs to be
+able to
+
+	<ul>
+	* (e) consume CodeDom trees.  CodeDom trees are an abstract
+	representation of programs in a form similar to a C# parse
+	tree, with embedded code snippets (unparsed strings).
+	Given a CodeDom tree, with the snippets in your language,
+	your language implementation needs to generate a (i) .NET
+	assembly and possibly also (ii) a source file in your language.
+
+	* (f) produce CodeDom trees.  For some applications,
+	your language implementation also needs to be able to
+	round-trip from CodeDom -> your language -> CodeDom.
+	</ul>
+
+and for some things it needs to
+
+	<ul>
+	* (g) generate *verifiable* IL
+	</ul>
+
+So when you hear all the hype about how language XYZ is a
+".NET language", make sure you ask which of these different
+things are supported.
+
+[For the record, Mercury currently supports (a).  We're working on
+(b) and (g), and on parts of (c) and (e).  We're never going to do (f), I very
+strongly doubt we'll ever do (d), and for (c) we might only ever support
+implementing interfaces, not deriving from classes.]
+
+</blockquote></i>
+
+** PInvoke 
+
+Q: What are the two major initiatives to implement PInvoke?
+
+A: Fergus Henderson answers:
+
+<i><blockquote>
+Many of the .NET APIs will need to be implemented using code that calls C/Unix
+APIs, such as stat().  The standard way of interfacing with native code from
+.NET code is to use "PInvoke".  However, there is a difficulty: many of
+these APIs are defined in terms of types such as C's `long' or `size_t'
+or the Posix `struct stat' whose representation varies depending on the
+platform (architecture/OS/C compiler).  There's no *portable* way of
+accessing those from .NET managed code.
+
+So, there are a couple of different approaches.
+One possibility is to access such routines by writing a wrapper, e.g. in C,
+that provides the same functionality without using types with a system-dependent
+representation.  The wrapper can then be directly accessed from portable
+.NET code.  The .NET code remains both source- and binary-portable;
+the wrapper code is source-portable, but needs to be compiled
+seperately for each target platform.  The drawback of this approach is
+that you have to write a lot of cumbersome wrapper code.
+
+Another possibility is to extend the .NET VM with support for an
+additional custom attribute, e.g. "[PosixType]".  The VM would then
+represent types tagged with this attribute in the same way that the
+underlying system represents those types.  With this approach, no
+wrapper code would be needed.  A drawback of this approach is that it
+pushes quite a bit of complexity into the VM; the VM would have to know
+the native representation of all types annotated with this attribute.
+Another drawback is that code using this extension might not work on
+different VMs.
+
+There have also been some other suggestions, but those are the two that
+I think are the best.
+</blockquote></i>
+
+Q: What is the problem implementing PInvoke?
+
+A: Again, from Fergus Henderson:
+
+<i><blockquote>
+There's no problem implementing PInvoke as specified in the ECMA
+specs and/or MS documentation.  It's just that PInvoke by itself
+doesn't solve all of the problems; in particular it doesn't solve
+the problem of C types whose representation is different on different
+systems.
+</blockquote></i>
+
+** CVS use
+
+Q: Why do we keep ChangeLogs and make the CVS commit messages be the
+   same?  One could be generated from the other
+
+A: There are a number of reasons for keeping ChangeLog files as well as
+   CVS commit files:
+
+   <ul>
+	* Offline programming: when people are traveling, CVS logs are
+          not available.
+
+	* Slow CVS access: Many people work over modem lines (very
+          typical for contributors in Europe, Asia, Latin America)
+          using CVS is slow and might not be available to you (cvs
+          server down, no anoncvs server available).
+
+	* ChangeLogs travel in a released tarball package, so it is
+	  possible to study the rationale of changes even after a
+	  project is long "released", or you only have the sources for
+	  the code. 
+
+	* ChangeLog are not metadata for each file, they are live
+          files that you can browse in the package that is being
+          distributed. 
+   </ul>
+
+Making the CVS commit message be the same as the ChangeLog has other
+benefits:
+
+   <ul>
+	* You can track down with `cvs log' what things were changed,
+          and match those to meaningful reports on the intentions of
+          the commit.
+
+	* When reading the commits-list, you can get a glimpse of the
+          changes without having to diff out or cvs update your tree.
+
+	* You can read off-line the changes that are being made
+          (asyncrouns operation).
+   </ul>
+
+This mechanism works very well for GNOME and other projects.
+
+Q: Should I use any of the special RCS keywords like $Id: devel-faq,v 1.1 2001/07/31 21:13:05 miguel Exp $, $Author: miguel $,
+   $Date: 2001/07/31 21:13:05 $, or $Revision: 1.1 $?
+
+A: Please avoid using those in the source code in the CVS.  They
+   are not really useful, and they cause a lot of conflicts when
+   people have separate CVS trees.
+
+   It was a nightmare with the Linux kernel when two people had their
+   private CVS trees and were submitting patches to the core.

+* Documentation
+
+	Although most of the concepts from Microsoft.NET can
+	be applied to the completed Mono platform, we do need to
+	have a complete set of free documentation written specifically
+	for Mono.
+
+	The documentation license we have chosen is the GNU Free
+	Documentation License (FDL), the standard for most documents
+	in the free software world. 
+
+	We need documentation on a number of topics:
+
+	<ul>
+
+		* The development tools (compilers, assembler tools,
+		  language reference, design time features).
+
+		* Frequently Asked Question compilations.
+
+		* HOWTO documents.
+
+		* The Class Libraries
+
+		* Tutorials on Mono and the specifics of running it. 
+
+		* A guide to Mono as compared to the Microsoft.NET
+		  Framework SDK
+
+	</ul>
+
+** Class Library documentation
+
+	We are moving to a new setup for documenting the class libraries, 
+	and you can read about it <a href="classlib-doc.html">here</a>.
+
+        A few words of warning and advice for class documentors:
+
+        A well-documented API can ease hours of frustration; as Mono
+        matures, robust and complete class library documentation will
+        become increasingly important.  As you write API documentation,
+        whether it is embedded in source files or in external Monodoc XML,
+        please keep the following in mind:
+
+        Plagarism, even if it's unintentional, is a Bad Thing(TM).
+        Microsoft's .NET Framework Class Library documentation is an
+        excellent resource for understanding the behavior and properties of
+        a type, and a lot of hard work went in to creating this (copyrighted)
+        resource.  Please don't copy from Microsoft's reference when
+        documenting a type.
+
+        To avoid this, I (<a href="mailto:jbarn@httcb.net">jbarn@httcb.net</a>)
+        suggest that you read the complete Microsoft documentation for a type,
+        ponder it for a while, and write the Mono documentation in your own
+        words.  While it's certainly okay to refer to the Microsoft
+        documentation to clarify your understanding of behavior or properties,
+        please don't open the Microsoft docs and refer to them for each member
+        you document.
+
+        There's a lot of domain expertise among the class library contributors;
+        let's put the same personal stamp on the class library documentation
+        that we have on the class libraries themselves.

+		* Save the script for your platform somewhere (e.g. /usr/local/bin)
+		* Make the script executable (i.e chmod 755 /usr/local/bin/mono-build.sh)
+		* Create a directory to hold the mono source, and the compiled binaries (e.g. mkdir ~/mono)
+		* Change to the new directory (i.e. cd ~/mono)
+		* run the script (i.e. /usr/local/bin/mono-build.sh)
+	</ul>
+
+	The script requires wget on either platform, and building the

+** Basics
+
+Q: What is Mono exactly?
+
+A: The Mono Project is an open development initiative sponsored by
+   Ximian that is working to develop an open source, Unix
+   version of the Microsoft .NET development platform.  Its objective
+   is to enable Unix developers to build and
+   deploy cross-platform .NET Applications.  The project will
+   implement various technologies developed by Microsoft that have now
+   been submitted to the ECMA for standardization.
+
+Q: What is the difference between Mono and the .NET Initiative?
+
+A: The ".NET Initiative" is a somewhat nebulous company-wide effort by
+   Microsoft, one part of which is a cross-platform development
+   framework.  Mono is an implementation of the development framework,
+   but not an implementation of anything else related to the .NET
+   Initiative, such as Passport, software-as-a-service, or
+   corporate rebranding.
+
+Q: What technologies are included in Mono?
+
+A: Mono contains a number of components useful for building new
+   software:
+
+	<ul>
+		* A Common Language Infrastructure (CLI) virtual
+		  machine that contains a class loader, Just-in-time
+		  compiler, and a garbage collecting runtime.
+
+		* A class library that can work with any language
+		  which works on the CLR.
+
+		* A compiler for the C# language.  In the future we
+		  might work on other compilers that target the Common
+		  Language Runtime.
+	</ul>
+
+
+   Windows has compilers that target the virtual machine from <a
+   href="http://msdn.microsoft.com/net/thirdparty/default.asp#lang">a
+   number of languages:</a> Managed C++, Java Script, Eiffel,
+   Component Pascal, APL, Cobol, Oberon, Perl, Python, Scheme,
+   Smalltalk, Standard ML, Haskell, Mercury and Oberon.
+
+   The CLR and the Common Type System (CTS) enables applications and
+   libraries to be written in a collection of different languages that
+   target the byte code
+
+   This means for example that if you define a class to do algebraic
+   manipulation in C#, that class can be reused from any other
+   language that supports the CLI.  You could create a class in C#,
+   subclass it in C++ and instantiate it in an Eiffel program. 
+
+   A single object system, threading system, class libraries, and
+   garbage collection system can be shared across all these languages.
+   
+Q: Where can I find the specification for these technologies?
+
+A: You can find the work-in-progress documentation from the T3G ECMA
+   group here:
+ 
+   <a href="http://www.dotnetexperts.com">http://www.dotnetexperts.com</a>
+
+Q: Will you implement the .NET Framework SDK class libraries?
+
+A: Yes, we will be implementing the APIs of the .NET Framework SDK
+   class libraries. 
+
+Q: Will you offer an ECMA-compliant set of class libraries?
+
+A: Eventually we will.  Our current focus is on interoperating
+   with the Microsoft SDK, but we will also offer an ECMA compliant
+   set of libraries. 
+
+Q: What does the name "Mono" mean?
+
+A: Mono is the word for `monkey' in Spanish. We like monkeys.
+
+Q: Is Mono usable?
+
+A: The JIT engine is usable on Intel x86 machines.  An interpreter
+   can be used on other non-Intel x86 machines.  
+
+   The class libraries are mature enough to run some real applications
+   (the compiler for instance, and every day more and more applications
+   are natively developed with Mono).
+
+Q: When will you ship it?
+
+A: Different parts of Mono will achieve usability at different stages,
+   once we are comfortable with the compiler, we will release "Mono Core",
+   which contains everything needed to develop applications with the base
+   class libraries.  This should be available at some point during 2002.
+
+   Other higher level class libraries (ASP.NET, ADO.NET, Windows.Forms) will
+   be released when they become stable. 
+
+Q: What major components will you include in Mono?
+
+A: Hopefully everything that Microsoft ships on their Framework
+   (ADO.NET, ASP.NET, Windows.Forms), and
+   we encourage third party developers to create reusable components that
+   work on both Mono and Windows.
+
+Q: How can I contribute?
+
+A: Check the <a href="contributing.html">contributing</a> section. 
+
+Q: Aren't you just copying someone else's work?
+
+A: We are interested in providing the best tools for programmers to
+   develop applications for Free Operating Systems.  We also want to help
+   provide the interoperability that will allow those systems to fit in
+   with other standards.
+
+   For more background, read the <a href="http://www.go-mono.com/rationale.html">Mono
+   Project white paper</a>.
+   the project.
+
+Q: Miguel said once that Mono was being implemented in COBOL. Is that true?.
+
+A: No. It was a joke.
+
+
+<a name="ximian"></a> 
+
+** The Ximian Role in the Mono Project
+
+Q: Why is Ximian working on .NET?
+
+A: Ximian is interested in providing the best tools for programmers to
+   develop applications for Free Operating Systems.  
+
+   For more information, read the project <a
+   href="rationale.html">rationale</a> page.
+
+Q: Will Ximian be able to take on a project of this size?  
+
+A: Of course not. Ximian a supporter of the Mono project, but the only way
+   to implement something of this size is for the entire free software
+   community to get involved. Visit the <a href="contributing.html">contributing</a> 
+   page if you'd like to help out.
+
+Q: What pieces will Ximian be working on?
+
+A: We will devote most of our resources to work on the pieces which are
+   on the critical path to release a development and execution
+   environment. Once the project is at a stage where it is useful in
+   the real world, it will achieve a critical mass of developers to
+   improve it further.
+
+Q: Will Ximian offer Mono commercially?
+
+A: When Mono is ready to be shipped Ximian will offer a commercial
+   support and services for Mono. 
+
+Q: Does Ximian provide consulting services around Mono?
+
+A: Yes, Ximian does provide consulting services around Mono to
+   make it suitable to your needs.  Porting the runtime engine,
+   customizing it, working on specific classes or tuning the code
+   for your particular needs. 
+
+Q: Will you wait until Mono is finished?
+
+A: Mono will ship on various stages as they mature.  Some people
+   require only a subset of the technologies, those will ship first.
+
+   More advanced features will take more time to develop.  A support
+   timeline will be available in June 2002.
+
+<a name="gnome"></a> 
+** Mono and GNOME
+
+Q: How is Mono related to GNOME?
+
+A: In a number of ways.  This project was born out of the need of
+   providing improved tools for the GNOME community, and will use
+   existing components that have been developed for GNOME when they
+   are available.  For example, we plan to use Gtk+ and Libart to
+   implement Winforms and the Drawing2D API and are considering
+   GObject support.
+
+Q: Has the GNOME Foundation or the GNOME team adopted Mono?
+
+A: Mono is too new to be adopted by those groups. We hope that the
+   tools that we will provide will be adopted by free software
+   programmers including the GNOME Foundation members and the GNOME
+   project generally.
+
+Q: Should GNOME programmers switch over to Mono now?
+
+A: It is still far to early for discussions of "switching over."  No
+   pieces of Mono will be ready within the next six months, and a
+   complete implementation is roughly one year away.
+
+   We encourage GNOME developers to continue using the existing tools,
+   libraries and components.  Improvements made to GNOME will have an
+   impact on Mono, as they would be the "backend" for various classes.
+
+Q: Will Mono include compatibility with Bonobo components? What is the
+   relationship between Mono and Bonobo?
+
+A: Yes, we will provide a set of classes for implementing and using
+   Bonobo components from within Mono.  Mono should allow you to write
+   Bonobo components more easily, just like .NET on Windows allows you
+   to export .NET components to COM.
+
+Q: Does Mono depend on GNOME?
+
+A: No, Mono does not depend on GNOME.  We use a few packages produced by
+   the GNOME team like the `glib' library.  
+
+Q: But will I be able to build GNOME applications?
+
+A: Yes, we will enable people to write GNOME applications using Mono.
+
+<a name="gui"></a>
+** GUI applications
+
+Q: Will Mono enable GUI applications to be authored?
+
+A: Yes, you will be able to build GUI applications.  Indeed, that is our
+   main focus.  We will provide both the Windows.Forms API and the Gtk# API.
+
+Q: What is the difference between Gtk# and System.Windows.Forms?
+
+A: Gtk# is a set of bindings for the Gtk+ toolkit for C# (and other
+   CIL-enabled languages).  System.Windows.Forms is an API defined
+   by Microsoft to build GUI applications.
+
+Q: Will I be able to run my smart clients on systems powered by Mono?
+
+A: As long as your applications are 100% .NET and do not make use
+   of P/Invoke to call Win32 functions, your smart client applications
+   will run on Mono platforms.
+
+Q: Where can I learn mora about Gtk#?
+
+A: The following <a href="http://gtk-sharp.sourceforge.net>link</a> sends you to the page of the project.
+
+Q: What can I do with Gtk#?. 
+
+A: Gtk# is becoming very usable and you can create applications and
+   applets like those you see in a GNOME desktop environment. It's 
+   easy to install so it's worth a try. 
+
+Q: How can I compile my HelloWorld.cs which uses Gtk#?.
+
+A: Try: mcs --unsafe -o HelloWorld.exe -r glib-sharp -r pango-sharp -r
+        atk-sharp -r gdk-sharp -r gtk-sharp -r gdk-imaging-sharp
+        HelloWorld.cs
+
+<a name="winforms"></a>
+** Mono and WinForms
+
+Q: Can you tell me why aren't you implementing WinForms?. 
+
+A: (This is based in an original mail to mono-list written by Miguel de
+   Icaza. You should read it for completion, but the core part is here).
+   
+   First, Windows.Forms is packed with quirks and is not that great of a 
+   toolkit in the first place. Up to the point of the unconfirmed rumor 
+   that Microsoft is working on a replacement for it. 
+
+   Once the runtime is done, we will very likely start contributing to
+   the Gtk# project ourselves, and we will likely start doing feasibility
+   work on getting Mono used by Gnome developers: full gnome apps and
+   extending existing applications.
+
+   Those interested in hacking on Windows.Forms are welcome to do so,
+   but Ximian will not likely look at it in the near future; if there is
+   enough demand, or I can be convinced that Windows.Forms is useful for
+   something Ximian might re-evaluate our resource allocation for this
+   task.
+
+   By doing native ports, we could use the same API on all those systems. 
+   Also, Gtk is mature enough, we know this because we have built an entire
+   desktop (and all sorts of very window system-specific hacks), and we
+   have built a bunch of productivity applications with it. 
+
+Q: What about VCL?.
+
+   Someone mentioned VCL. The only problem with the VCL is that it can
+   only be used for GPL applications (or I guess you could license it from
+   Borland for your app), and would have to be ported from Delphi to C# 
+   (or someone would have to write a CIL compiler for it).
+
+Q: What about doing something like the eclipse project (www.eclipse.org)? 
+
+A: The Eclipse toolkit is not a general purpose toolkit.  It will require a
+   lot of work before it is such a thing.  It is a toolkit used to
+   implement a development environment.
+
+
+<a name="msft"></a>
+** Mono and Microsoft
+
+Q: Is Microsoft helping Ximian with this project?
+
+A: No. Ximian CTO Miguel de Icaza had a friendly conversation with
+   Microsoft software architect David Stutz, but that's about the
+   extent of the contact. Microsoft is interested in other
+   implementations of .NET and are willing to help make the ECMA spec
+   more accurate for this purpose.
+
+   Ximian representatives have also spoken with Sam Ruby at the ECMA
+   TG3 committee to discuss the same issues.
+
+Q: Is Microsoft or Corel paying Ximian to do this?
+
+A: No.
+
+Q: Do you fear that Microsoft will change the spec and render Mono
+   useless?
+
+A: No.  Microsoft proved with the CLI and the C# language that it was
+   possible to create a powerful foundation for many languages to
+   interoperate.  We will always have that.  
+
+   Even if changes happened in the platform which were undocumented,
+   the existing platform would a value on its own.
+
+Q: Are you writing Mono from the ECMA specs?
+
+A: Yes, we are writing them from the ECMA specs and the published
+   materials in print about .NET.
+
+Q: If my applications use Mono, will I have to pay a service fee?
+
+A: No.  Mono is not related to Microsoft's initiative of
+   software-as-a-service.
+
+Q: Is the Mono Project is related to the Microsoft Hailstorm effort?  Is
+   Ximian endorsing Hailstorm?  
+
+A: No.  The Mono Project is focused on providing a compatible set of
+   tools for the Microsoft .NET development platform.  It does not
+   address, require, or otherwise endorse the MS Passport-based
+   Hailstorm single sign-on system that is part of Windows XP and
+   other services.
+
+Q: Will Mono or .NET applications depend on Microsoft Passport?
+
+A: No. MS Passport is unrelated to running .NET compatible applications
+   produced with the Mono tools.  The only thing you will need is a
+   just-in-time compiler (JIT).
+
+Q: What is a 100% .NET application?
+
+A: A `100% .NET application' is one that only uses the APIs defined
+   under the System namespace and does not use PInvoke.  These
+   applications would in theory run unmodified on Windows, Linux,
+   HP-UX, Solaris, MacOS X and others. 
+
+Q: If Microsoft will release a port of their .NET platform under the
+   `Shared Source' license, why should I bother with anything else?
+
+A: The Shared Source implementation will be expensive and its uses
+   will be tightly restricted, especially for commercial use. We are
+   working towards an implementation that will grant a number of
+   important rights to recipients: use for any purpose,
+   redistribution, modification, and redistribution of modifications.
+
+   This is what we call <a
+   href="http://www.gnu.org/philosophy/free-sw.html">Free Software</a>
+
+Q: Is Mono a free implementation of Passport?
+
+A: No. Mono is just a runtime, a compiler and a set of class
+   libraries.
+
+Q: Will the System.Web.Security.PassportIdentity class mean
+   that my software will depend on Passport?
+   
+A: No.  Applications may use that API to contact a Passport site, but
+   are not required to do so.
+
+   As long as your application does not use Passport, you will not
+   need Passport.  
+
+Q: Will Mono running on Linux make Passport available for Linux?
+
+A: No.  However, the Passport toolkit for Linux-based web servers is
+   available from Microsoft.
+
+Q: Will Mono allow me to run Microsoft Office on Linux?
+
+A: No, it will not.  Microsoft Office is a Windows application.  To
+   learn more about running Windows applications on Intel Unix systems
+   refer to <a href="http://www.winehq.com">the Wine Project</a>.
+
+<a name="pnpproject"></a>
+** Mono and Portable.NET
+
+Q: What are the differences between Mono and Portable.NET?
+
+A: Most of Mono is being written using C#, with only
+   a few parts written in C (The JIT engine, the runtime, the
+   interfaces to the garbage collection system).  
+
+   It is easier to describe what is unique about Mono:
+   <ul>
+     <li> A self-hosting C# compiler written in C#, which is clean, easy
+          to maintain.
+
+     <li> A multi-platform runtime engine: both a JIT engine and an
+          interpreter exist.  The JIT engine runs currently on x86
+          systems, while the interpreter works on Sparc, StrongARM and
+          PowerPC systems.  
+
+     <li> Supports Linux, Windows and Solaris at this point.
+
+     <li> The JIT engine is written using a portable instruction
+          selector which not only generates good code (we are told
+          that we are faster than Rotor, but it is hard to tell) but
+          is also the foundation to retarget the JIT engine to other
+          systems.  
+
+          The system employed is described in various compiler
+          books and it is very similar to what is described in the 
+          book that covers LCC, the Ansi C retargetable C compiler.
+
+     <li> The JIT engine supports inlining, constant folding and propagation,
+
+     <li> Full support for remoting in the runtime, but the class 
+          libraries are still behind.
+
+     <li> The C# compiler, the JIT engine and the class libraries are
+          mature enough that the whole system is self-hosting, ie, that
+          it can be fully developed with itself at this point.
+
+     <li> We are not yet done, and there is a lot of work left to be
+          done
+
+     <li> We have a great community of developers, without which Mono
+          would not be possible.
+
+     <li> We will provide an ahead of time compilation mode in the 
+          future.

+** Web Services
+
+Q: How is Mono related to Web Services?
+
+A: Mono is only related to Web Services in that it will implement the
+   same set of classes that have been authored in the .NET Framework
+   to simplify and streamline the process of building Web Services.
+
+   But most importantly, Mono is an Open Source implementation of the
+   .NET Framework.
+
+Q: Can I author Web Services with Mono?
+
+A: You will be able to write Web Services on .NET that run on Mono and
+   viceversa. 
+
+Q: If Mono implements the SDK classes, will I be able to write and
+   execute .NET Web Services with it?
+   
+A: Yes.  When the project is finished, you will be able to use the
+   same technologies that are available through the .NET Framework SDK
+   on Windows to write Web Services.
+
+Q: What about Soup?  Can I use Soup without Mono?
+
+A: Soup is a library for GNOME applications to create SOAP servers and
+   SOAP clients, and can be used without Mono.  You can browse the
+   source code for soup using <a
+   href="http://cvs.gnome.org/bonsai">GNOME's Bonsai</a>.
+
+Q: Can I use CORBA?
+
+A: Yes. The CLI contains enough information about a class that
+   exposing it to other RPC systems (like CORBA) is really simple, and
+   does not even require support from an object.  
+
+   We will be implementing CORBA interoperation as an extension to the
+   Mono classes so that we can integrate with Bonobo, just like
+   Microsoft provides COM interoperation classes and support
+   mechanisms. 
+
+Q: Can I serialize my objects to other things other than XML?
+
+A: Yes, although the serializing tools have not yet been planned, and
+you would probably have to implement them yourself.
+
+Q: Will Mono use ORBit?
+
+A: No. Mono will be using a new implementation of CORBA that isn't still started. 
+
+<a name="devel"></a>
+** Development Tools and Issues
+
+Q: Will it be possible to use the CLI features without using bytecodes
+   or the JIT?
+
+A: Yes. The CLI engine will be made available as a shared library.
+   The garbage collection engine, the threading abstraction, the
+   object system, the dynamic type code system and the JIT will be
+   available for C developers to integreate with their applications if
+   they wish to do so. 
+
+Q: Will you have new development tools?
+
+A: With any luck, Free Software enthusiasts will contribute tools to
+   improve the developer environment.  These tools could be developed
+   initially using the Microsoft implementation of the CLI and then
+   executed later with Mono.
+
+Q: What kind of rules make the Common Intermediate Language useful for
+   JITers?
+
+A: The main rule is that the stack in the CLI is not a general purpose
+   stack.   You are not allowed to use it for other purposes than
+   computing values and passing arguments to functions or return
+   values.  
+
+   At any given call or return instruction, the types on the stack
+   have to be the same independently of the flow of execution of your
+   code. 
+
+Q: Is it true that the CIL is ideal for JITing and not efficient for
+   interpreters?
+
+A: The CIL is better suited to be JITed than JVM byte codes, but you
+   can interpret them as trivially as you can interpret JVM byte
+   codes. 
+
+Q: Isn't it a little bit confusing to have the name of "XSP" (the same 
+   as in the Apache Project) for the ASP.NET support in Mono?.
+
+A: In Mono, xsp is just the name of the C# code generator for ASP.NET 
+   pages. In the Apache Project, it is a term for the "eXtensible Server 
+   Pages" technology so as they are very different things, they don't 
+   conflict.
+
+Q: What about using something like Jabber instead of the System.Messaging 
+   namespace?.
+
+A: In short, MSMQ is not something like Jabber, but asynchronous messaging 
+   through queues. Usefull queues do more than serialize messages, they are 
+   also platform bridges.
+
+Q: Are you supporting XMLDocument and relatives?.
+
+A: Currently, we aren't implementing them yet. It would require updates to 
+   most of the XmlNode derivatives so it's not a trivial task. We are 
+   currently focusing on getting XPath support working. 
+
+Q: Is there any plan to develop an aspx server for Mono?.
+
+A: The webserver turned out to be very simple compared to the rest of the 
+   work. Gonzalo has got the page generator mostly done (a module called 
+   xsp, who has nothing to do with the XSP term used in the Apache Project).
+   Patrik has done a lot of the work to get the ProcessRequest to work.
+   You can try to help in the final touches to the System.Web classes and
+   writing regression tests for the widgets we have.
+
+Q: Is there any way I can develop the class libraries using linux yet?
+
+A: Yes. Some class libraries can be developed on Linux. Search for
+   Paolo's post (he lists which classes can be compiled fine now).
+
+Q: Is there any way I can install a known working copy of mono in /usr, 
+   and an experimental copy somewhere else, and have both copies use 
+   their own libraries? (I'm still not very good at library paths in 
+   linux)
+
+A: Yes. Just use two installation prefixes.
+
+
+<a name="asp">
+** Mono and ASP.NET
+
+Q: Is Mono supporting ASP.NET?
+
+A: Yes. The development of the support for ASP.NET comes in various stages, 
+   here is what Gonzalo has been working on: 1. The Parser. 2. Getting the 
+   parser to generate output compatible with ASP.NET. 3. Running the sample 
+   output with the real Microsoft runtime but using our generated page. 4. 
+   Running the sample with our classes with the .NET runtime. 5. Running 
+   our sample code with our classes with our runtime. This is the process 
+   we are following. Currently Gonzalo has reached point 5.
+
+<a name="java">
+** Mono and Java
+   
+Q: Why don't you use Java?  After all, there are many languages that
+   target the Java VM.
+
+A: You can get very good tools for doing Java development on free
+   systems right now.  <a href="http://www.redhat.com">Red Hat</a> has
+   contributed a <a href="http://gcc.gnu.org">GCC</a> <a
+   href="http://gcc.gnu.org/java">frontend for Java</a> that can take
+   Java sources or Java byte codes and generate native executables; <a
+   href="http://www.transvirtual.com">Transvirtual</a> has implemented
+   <a href="http://www.kaffe.org">Kaffe</a> a JIT engine for Java;
+   Intel also has a Java VM called <a
+   href="http://www.intel.com/research/mrl/orp">ORP</a>.
+
+   The JVM is not designed to be a general purpose virtual machine.
+   The Common Intermediate Language (CIL), on the other hand, is
+   designed to be a target for a
+   wide variety of programming languages, and has a set of rules
+   designed to be optimal for JITers.
+
+Q: Could Java target the CLI?
+
+A: Yes, Java could target the CLI.  We have details on a <a
+   href="ideas.html#guavac">project</a> that someone could take on to
+   make this happen.  
+
+   Microsoft has an implemenation of the Java language called J# that
+   can target the CIL execution engine. 
+
+Q: Is it possible to write a JVM byte code to CIL convertor?
+
+A: Yes, it is possible.  Here are a few starting point:
+
+	<ul>
+        	* A byte code representation is really a flattened forest of
+          	  trees.  Look at the Mono JIT engine to see how we compute
+          	  the basic blocks (this is used to figure out the "trees").
+
+          	  The forest is just an array of trees.
+
+          	  Indeed, run the JIT engine with -d (mono -d prog.exe) and
+          	  you will see how these trees look like.
+
+            	  You will have to do something similar for Java.
+
+        	* Each "forest of trees" has a meaning.  This meaning can now
+          	  be translated into the equivalent "meaning" in CLR-land.
+	</ul>
+
+Q: Could mono become a hybrid cil/java platform?
+
+A: No. It is quite far from the philosophy of the project. The idea of Mono 
+   is, to have only _one_ VM, on which all can run. And if there existing a 
+   binary-converter from Java-.class to IL and if there existing something 
+   like J-Sharp on Mono, you can write programs in Java, which than can run 
+   on Mono. You do not need two bindings (like your example: GTK-Sharp _and_ 
+   Java-Gnome). You need only _one_ of it (GTK-Sharp). Thats the idea of Mono.
+   An other point is, that there are no people, who use OpenSource-JVMs. They 
+   all prefer Suns original. But for Unix there don't exist a .NET-Framework. 
+   So it is possible, that in the future Mono is the standard .NET for unixes.
+
+<a name="extending"></a>
+** Extending Mono
+
+Q: Would you allow other classes other than those in the
+   specification?
+
+A: Yes.  The Microsoft class collection is very big, but it is by no
+   means complete.  It would be nice to have a port of `Camel' (the
+   Mail API used by Evolution inspired by Java Mail) for Mono
+   applications.  
+
+   You might also want to look into implementing CORBA for Mono.  Not
+   only because it would be useful, but because it sounds like a fun
+   thing to do, given the fact that the CLI is such a type rich
+   system. 
+
+   For more information on extending Mono, see our <a
+   href="ideas.html">ideas</a> page.
+
+Q: Do you plan to Embrace and Extend .NET?
+
+A: Embracing a good technology is good.  Extending technologies in
+   incompatible ways is bad for the users, so we do not plan on 
+   extending the technologies.
+
+   If you have innovative ideas, and want to create new classes, we 
+   encourage you to make those classes operate correctly well in both
+   Mono and .NET.
+
+Q: Is there any way I can develop the class libraries using linux yet?
+
+A: Yes. Some class libraries can be developed on Linux. Search for
+   Paolo's post (he lists which classes can be compiled fine now).
+
+Q: Is there any way I can install a known working copy of mono in /usr, 
+   and an experimental copy somewhere else, and have both copies use 
+   their own libraries? (I'm still not very good at library paths in 
+   linux)
+
+A: Yes. Just use two installation prefixes.
+
+
+<a name="portability"></a>
+** Portability
+
+Q: Will Mono only work on Linux?
+
+A: Currently, we are doing our work on Linux-based systems and
+   Windows.  We do not expect many Linux-isms in the code, so it
+   should be easy to port Mono to other UNIX variants.   
+
+Q: What about Mono on non Linux-based systems?
+
+A: Our main intention at Ximian is to be able to develop GNOME
+   applications with Mono, but if you are interested in providing a
+   port of the Winform classes to other platforms (frame buffer or
+   MacOS X for example), we would gladly integrate them, as long
+   they are under an open source license.  
+
+Q: What operating systems/CPUs do you support
+
+A: Mono currently runs on Linux, Windows, Solaris and FreeBSD.
+   There is a JIT engine available for x86 processors that can
+   generate code and optimizations tailored for a particular CPU.
+
+   Interpreters exist for the SPARC, PowerPC and StrongARM cpus.
+
+Q: Does Mono run on Windows?
+
+A: Yes.   The Compiler and the runtime both run on Windows.
+
+Q: When will mono and mcs compile on Linux?.
+
+A: That happend a long time ago. Know you can download and compile 
+   them or even install them from already made binary packages for 
+   Windows and for Linux (RPM/DEB).
+
+Q: Will I require Cygwin to run mono?
+
+A: No.  While you'll need it to compile it, it runs without cygwin and does not even require cygwin1.dll
+
+Q: Will Mono depend on GNOME?
+
+A: It will depend only if you are using a particular assembly (for
+   example, for doing GUI applications).  If you are just interested
+   in Mono for implementing a `Hello World Enterprise P2P Web
+   Service', you will not need any GNOME components.
+
+Q: Is anyone working on porting Mono to IA-64?
+
+A: Nobody is working on such port.
+
+Q: If I were about to start a Mono port to IA-64,would the same lburg code 
+   generator work for IA-64 also? or anything else need to be used for code 
+   generation(as the processor architecture is totally different from IA32)
+
+A: The lburg approach can be use for any processor architecture. But you might
+   think in another better approach.
+
+<a name="reuse"></a>
+** Reusing Existing Code
+
+Q: What projects will you reuse or build upon?
+
+A: We want to get Mono in the hands of programmers soon.  We are
+   interested in reusing existing open source software.
+
+Q: What about Intel's research JIT framework, ORP?
+
+A: At this time, we are investigating whether we can use elements of
+   ORP for Mono.   ORP is a research JIT engine that has a clearly
+   defined API that splits the JIT from the GC system and the actual
+   byte code implementation.
+
+   We are using some pieces of ORP (Their code generation interface)
+   and we use it as a source of inspiration for optimizations.  Paolo
+   and Dietmar consider ORP as being one of the best JIT engines out
+   there (and their research work and papers are very useful if you are
+   interested in JIT technology).
+
+Q: What about using GNU Lightning?
+
+A: We are not using GNU Lightning.  Our JIT is using an instruction
+   selector based on tree-pattern matching, and a code generation
+   interface that is very tied to the current architecture.
+
+Q: Will I be able to use Microsoft SQL Server 2000 or will I need to switch
+   to a specific Open Source Database. Will I need to recode?
+
+A: There should not be any need to recode.
+
+Q: What do I need to watch out for when programming in VB.NET so that I'm
+   sure to be able to run those apps on Linux?
+
+A: Not making any PInvoke or DLL calls should and not using anything in
+   the Microsoft.* namespaces should suffice. Also do not use any 
+   Methods/Classes marked as "This type/method supports the .NET Framework 
+   infrastructure and is not intended to be used directly from your code." 
+   even if you know what these classes/methods do.
+
+Q: Will built-in reporting be supported for crystal reports? This is a
+   heavily used part of our system.
+
+A: Probably not. Crystal Reports are propriety. Someone may try to emulate
+   the behaviour, but no-one has yet volunteered.
+
+Q: Who about writing to the registry? As I understand it, Linux does not have
+   a counterpart to the registry. Should I avoid relying on that feature?
+
+A: Try to avoid it. Although there would be a emulation for registry in
+   Mono too. GNOME does have a registry like mechanism for configuration. But
+   Even if gnome has a configuration system similar to the registry, the keys 
+   will not be equal, so you will probably end up having to do some runtime 
+   detection, and depending on this load an assembly that has your 
+   platform-specific hacks.
+
+Q: System.Data.SqlClient with FreeTDS, will you port parts of these to C# and 
+   use them?
+
+A: if their license is compatible with mono's, yes, we'd think about porting 
+   them. If not, we'll continue with the plan of using FreeTDS.
+
+<a name="gcc"></a>
+** Mono and GCC
+
+Q: Are you working on a GCC front-end to C#? A GCC backend that will
+   generate CIL images? What about making a front-end to GCC that
+   takes CIL images and generates native code?
+
+A: We are currently seeking volunteers for those projects.
+   Visit the <a href="contributing.html">contributing</a> section if
+   you are interested.
+
+Q: But would this work around the GPL in the GCC compiler and allow
+   people to work on non-free front-ends?
+
+A: People can already do this by targeting the JVM byte codes (there
+   are about 130 compilers for various languages that target the JVM).
+
+Q: Why are you writing a JIT engine instead of a front-end to GCC?
+
+A: We want the JIT engine and runtime engine because they will be able
+   to execute CIL executables generated on Windows, and so no recompilation 
+   will be necessary.
+
+<a name="performance"></a>
+** Performance
+
+Q: How fast will Mono be?
+
+A: We can not predict the future, but a conservative estimate is that
+   it would be at least `as fast as other JIT engines'.
+
+   We would like to ship various JIT engines with Mono, just like
+   Microsoft has done with their .NET development platform. We could
+   provide a faster, JIT for fast load times but lower performance,
+   and an and an optimizing JIT that would be slower at generating
+   code but produce more optimal output.
+
+   The CIL has some advantages over the Java byte code:  it is really
+   an intermediate representation and there are a number of
+   restrictions on how you can emit CIL code that simplify creating
+   better JIT engines.
+
+   For example, on the CIL, the stack is not really an abstraction
+   available for the code generator to use at will.  Rather, it is a
+   way of creating a postfix representation of the parsed tree.  At
+   any given call point or return point, the contents of the stack are
+   expected to contain the same object types independently of how the
+   instruction was reached.
+
+<a name="licensing"></a>
+** Licensing
+
+Q: Will I be able to write proprietary applications that run with
+   Mono?
+
+A: Yes.  The licensing scheme is planned to allow proprietary
+   developers to write applications with Mono.
+   
+Q: What license or licenses are you using for the Mono Project?
+
+A: The C# Compiler is released under the terms of the <a 
+   href="http://www.opensource.org/licenses/gpl-license.html">GNU GPL</a>.  The runtime
+   libraries are under the <a
+   href="http://www.opensource.org/licenses/lgpl-license.html">GNU
+   Library GPL</a>.  And the class libraries are released
+   under the terms of the <a
+   href="http://www.opensource.org/licenses/mit-license.html">MIT X11</a>
+   license.
+
+Q: I would like to contribute code to Mono under a particular
+   license. What licenses will you accept?
+
+A: We will have to evaluate the licenses for compatibility first,
+   but as a general rule, we will accept the code under the same
+   terms of the "container" module. 
+
+<a name="patents></a>
+** Patents
+
+Q: Could patents be used to completely disable Mono (either submarine
+   patents filed now, or changes made by Microsoft specifically to
+   create patent problems)?
+
+A: No.  First, its basic functional capabilities have pre-existed too
+   long to be held up by patents.  The basic components of Mono are
+   technologically equivalent to Sun's Java technology, which has been
+   around for years.  Mono will also implement multi-language and
+   multi-architecture support, but there are previous technologies
+   such as UCSD p-code and ANDF that also support multiple languages
+   using a common intermediate language.  The libraries are similar
+   to other language's libraries, so again, they're too similar to
+   be patentable in large measure.
+
+   However, if Microsoft does patent some technology, then our plan is
+   to either (1) work around it, (2) chop out patented pieces, (3) 
+   find prior art that would render the patent useless.
+ 
+   Not providing a patented capability would weaken the
+   interoperability, but it would still provide the free software /
+   open source software community with good development tools, which
+   is the primary reason for developing Mono.  
+
+<a name="etc"></a> 
+** Miscellaneous Questions
+
+Q: You say that the CLI allows multiple languages to execute on the
+   same environment.  Isn't this the purpose of CORBA?
+
+A: The key difference between CORBA (and COM) and the CLI is that the
+   CLI allows "data-level interoperability" because every
+   language/component uses the same data layout and memory management.
+
+   This means you can operate directly upon the datatypes that someone
+   else provides, without having to go via their interfaces.  It also
+   means you don't have to "marshall" (convert) parameters (data
+   layouts are the same, so you can just pass components directly) and
+   you don't have to worry about memory managment, because all
+   languages/components share the same garbage collector and address
+   space.  This means much less copying and no need for reference
+   counting.
+
+Q: Will you support COM?
+
+A: The runtime will support XPCOM on Unix systems and COM on Windows.
+   Most of the code for dynamic trampolines exists already.
+
+Q: Will Ximian offer certifications on Mono or related technologies?. 
+
+A: It's possible. But there is no plan about this. So the short answer is no.
+
+Q: Are there any Boehm's gc binaries?
+
+A: Yes. You can find them <a href="http://java.thn.htu.se/~toor/">here</a>
+
+Q: I have get into trouble when trying to build the site in my Linux box, what
+   can I do?.
+
+A: Try to change the line "./mono-rss.exe ../index deploy/index.rss" for
+   "mono ./mono-rss.exe ../index deploy/index.rss"
+
+Q: How can I report a bug?
+
+A: The best thing is to track down the bug and provide a simple test to
+   reproduce the bug. You can then add the bug to bugzilla:
+   http://bugzilla.ximian.com/enter_bug.cgi or simply send it to 
+   mono-list@ximian.com.
+
+Q: Does mcs support the same command line options as the MS C# 
+   compiler?
+
+A: The Mono C# compiler on CVS now supports the same command line
+   arguments as the Microsoft C# compiler does.

+		  it to generate .NET code rather than JVM byte
+		  codes. 
+
+		  This should be a pretty straightforward task.
+		  Guavac has the advantage of being written in C++ and
+		  it could be compiled with the Microsoft Managed C++
+		  compiler and produce a .NET executable with it.
+
+TODO=CORBA,CORBA implementation
+		* Build a CORBA interoperability engine for the CLR.
+		  You do not need to do all of the work, just talking
+		  the protocol will get us a long way (<a
+		  href="http://www.omg.org">The OMG site</a> has the
+		  CORBA specs).
+
+		  Get in touch with David Taylor (dtaylo11 at bigpond
+		  dot net dot au) as he has been working on this
+		  project.
+
+TODO=Bonobo,Bonobo for Mono
+		* Once CORBA is done, implement the Bonobo interfaces
+		  to allow people to use Bonobo components in Mono and
+		  Mono components with Bonobo.  The best of both worlds!
+
+TODO=moniker,Object Naming System with Monikers
+		* A naming space for Mono.  An object naming space is
+		  a very powerful tool.  Bonobo implements a moniker
+		  system that is more powerful than the original
+		  moniker concept that was pioneered by COM/OLE in the
+		  Microsoft world.
+
+		  Our implementation builds on a concept, and we have
+		  made it simpler, more powerful, more extensible and
+		  a much better mechanism than the equivalent monikers
+		  on Windows. 
+
+		  Implementing Mono monikers would benefit both
+		  Windows users using .NET and Mono users on Unix and
+		  Windows.  
+
+		  Here is <a

+
+	Paolo today got mono to complete host itself on Linux.  This
+	means that we can now compile the `corlib' using the Mono C#
+	compiler and the Mono runtime.
+
+	Compiling the corlib was rather tricky, because the types that
+	the compiler uses during the compilation process will come
+	from the source code it is compiling.  
+
+	After a few months of work, we have finally fleshed out all
+	the remaining bugs.  Now the next step is to update the makefiles
+	to compile with the Mono tool-chain.
+
+	A recapitulation:
+	<ul>
+		* The Mono C# compiler was able to compile itself on December 28th, 2001.
+		  The resulting image contained errors though.
+
+		* The Mono C# compiler was able to self-compile in on
+		  January 3rd, 2002.  Becoming a self-hosting compiler on Windows.
+
+		* The Mono runtime matured enough by March 12, 2002 that it
+		  was able to bootstrap the Mono C# compiler on Linux using our interpreter.
+		  This means that our development tool was self sufficient.
+
+		* On March 26th, the JIT engine was fixed, so we could use this to
+		  run the compiler on Linux.
+
+		* Martin fixed the remaining bugs in the compiler that stopped it from
+	 	  compiling the `corlib'.  The resuling image still contained errors though.
+
+		* On July 8th, Radek got the PowerPC port to bootstrap
+		  the C# compiler.  This is important, because it exposed
+	  	  various tricky issues in a big-endian system.
+
+		* Today: we can bootstrap the compiler using libraries
+		  and the compiler compiled with itself on Linux.  The process is complete.
+	</ul>
+
+	In the meantime, Dietmar has quietly implemented the remaining
+	pieces of Marshalling in the Mono runtime.   This is very
+	important for the Gtk# guys to move on with their bindings.
+
+	To make things more interesting, he replaced most of the
+	architecture specific code generation for trampolines
+	(delegates, invocations, function and p/invoke trampolines) to
+	use CIL.  This CIL is then compiled on the flight by the JIT
+	Compiler engine.  By doing this, we have reduced the burden to
+	port the JITer to new architectures, and that our trampoline
+	code is cross platform.
+
+@item Looking for volunteers
+
+	We are looking for volunteers to help complete various pieces
+	of Mono and help move the project forward, we need
+	contributions to:
+
+	<ul>
+		* More tests to the existing class libraries.
+	
+		* Finish existing class libraries, check our <a
+		href="class-status.html">class status</a> pages to see
+		all the missing things.  There are open tasks all over
+		the place: XML, Database access, enterprise services,
+		configuration, ASP.NET, Drawing APIs, and more.
+
+		* Since we have now ASP.NET running, we would like to 
+		create an ASP.NET application to maintain our class
+		library documentation.
+
+		We have some special needs (read them <a
+	 	href="classlib-doc.html">here</a>).     There is a
+		prototype written using Windows.Forms, but we believe
+		it will be faster to have this done using ASP.NET (and
+		it is also a nice way of stress testing it).
+
+		* Support for the VB runtime: we need contributions
+		to make our VB runtime mature enough to host
+		applications compiled with the VB.NET to run with
+		Mono.
+
+		* We need people to help write the documentation: you
+		can start editing our XML files by hand, and once we
+		have the ASP.NET tool, upgrade to that. 
+	</ul>

+
+	Ajay was the first to notice <a
+	href="http://lists.ximian.com/archives/public/mono-list/2002-July/000641.html">
+	Mono's first birthday</a>.
+
+	In a year, we have achieved plenty:
+	<ul>
+		* 94 contributors with CVS access (84 non-Ximian developers).
+		* A complete CLI implementation:
+		<ul>
+			<li> A fast and performing x86 JIT engine (inlining, constant propagation).
+			<li> An interpreter for other systems (PPC, Sparc, StrongArm).
+		</ul>
+		* A self-hosting C# compiler, which can compile its class libraries.
+		* 37,140 file changes in CVS.
+		* 92,000 lines of C code.
+		* 437,000 lines of C# code (compiler, classes, tests)
+		* A working core for ASP.NET and ADO.NET.
+		* Major subsystems are functional: RegularExpressions,
+		  System.XML, XML.Schema, System.Data, System.Web.
+		* The Gtk# project, which is maturing rapidly.
+	</ul>
+
+	Thanks to everyone who has made Mono possible with their
+	feedback, regression tests, their comments, their help on the mailing
+	list, code contributions, complete classes, bug reporting, the
+	countless hours of bug hunting.  This project would not have
+	been possible without every contribution.  
+
+	It has been a great year for everyone involved in the
+	project.  I think we have built a new and exciting community.
+
+	Now we have a solid foundation to build on, so this next year
+	looks even more exciting: not only because we will see more
+	Mono applications, but we will begin using Mono as an
+	`library' to be linked with applications that want to get
+	scripting-like features; Gtk# is our ticket to create nice
+	GNOME applications; And we will be developing CORBA bindings
+	to integrate with other object systems.
+
+	Also, for those interested in optimizations and tuning, this
+	year we will get to play with more advanced optimizations and
+	all kinds of interesting research ideas for improving Mono
+	code generation.
+
+	A special thanks to the Mono developers at Ximian for managing
+	to survive their manager and a special thanks to our
+	regression test marshal Nick Drochak, who has been hunting
+	down, and fixing code in our class libraries and keeping us on
+	track for so long.

+
+	Radek today fixed the last bugs to get Mono to self host on
+	Linux/PowerPC.
+
+	Alp Toker has released version 0.5 of <a
+	href="http://www.atoker.com/phonic/">Phonic</a>, a media
+	player for .NET. Phonic makes extensive use of Mono-developed
+	technologies such as Gtk# and csvorbis (Ogg player ported by
+	Mark). Hopefully we will be seeing many more exciting
+	applications like these in the near future.
+
+	Dietmar has been moving a lot of the architecture specific
+	code in the JIT engine to our internal representation.  This
+	means that porting the JIT is simpler now, as there is less
+	architecture-specific code to maintain.  The inliner, constant
+	folder and constant propagation are also done at the
+	architecture independent layer.
+
+	Gonzalo is now running the sample ASP.NET applications on
+	Linux with the Mono runtime.  It still needs polishing though,
+	and help with the various ASP.NET controls would be
+	appreciated.  The ASP.NET community seems more poor than the
+	PHP community, we need to have a few open source controls to
+	do things dynamic rendering (libart+gdk-pixbuf again can do
+	most of the work), charts and components like the kind of
+	thing you see in the PHP universe: to bring nice GPL code to
+	the masses of Windows developers, lure them into the world of
+	Linux.
+
+	Dick has also got us the new Process implementation that
+	implements the Win32 semantics.  Now only redirection is
+	missing.

+
+	Martin Baulig fixed the remaining bugs that prevented MCS to
+	compile our corlib.  The compilation was tricky because of the way
+	MCS bootstraps the compile (internally mcs uses the types that are
+	being defined at that point to perform compares).
+
+	Martin and Paolo have been working hard on fixing the
+	remaining issues.  Currently 102 test pass and 15 fail with
+	our resulting corlib.
+
+	Jesus' SoapFormatter classes are now in CVS.
+
+	I have been redoing the type lookup system for MCS.  The

+@item Apr 20, 2002
+
+	Some updates from the hacking lines:
+
+	<b>The web:</b> Patrik Torstensson last week contributed the
+	http runtime support and started work on thread pools.  This
+	is part of the ASP.NET support.
+
+	<b>Docs:</b> John Barnette, John Sohn and Adam Treat have been
+	hacking on MonoDoc.
+
+	<b>ADO.NET:</b> Daniel Morgan and Rodrigo Moya have been
+	working on the <a href="ado-net">ADO.NET</a> support, and got
+	the first signs of life this week (we can connect, insert
+	rows; do transactions: commit/rollback; SQL errors and
+	exceptions work).  Check <a
+	href="mailing-lists.html">mono-patches</a> for all the
+	goodies.
+
+	<b>Optimizations:</b> A number of optimizations in the runtime
+	made the compiler twice as fast this week:
+
+	Early this week Patrik started the string
+	rewrite in the runtime.  Today Dietmar finished the
+	constructors and deployed the new layout. 
+
+	Paolo got the JIT engine to generate profiles, which were in
+	turn used to find hot spots in Reflection, which he improved.
+
+	Daniel Lewis (of Regex fame) noticed the performance issues
+	with our current array layout, and contributed a new array
+	representation.
+
+	At the same time Dietmar started the the JIT inline code and
+	implemented constant propagation.  These two optimizations
+	together are very powerful.
+
+	<b>Bug fixing:</b> And of course everyone has been helping out
+	with the bug fixing (Duncan, Gonzalo, Jonathan, Miguel, Nick,
+	Ravi, Sergey)
+
+
+@item Apr 18, 2002
+
+	Dietmar's inlining for the JIT engine just landed into
+	CVS. This is only a first cut and more improvements will come later.
+
+	Patrik, Paolo, Dietmar and Gonzalo have been busy optimizing
+	our class libraries and runtime engine to become faster. Many changes
+	on CVS as well.

+
+	Martin has been working on our debugging infrastructure, both
+	on the JIT side of things (adding dward support) as well as on
+	the class libraries (so that MCS can start generating
+	debugging information).
+	
+	Jason and Kral keep working on the System.Xml namespace,
+	allowing Mike to move more to self-hosting his Gtk# code.  
+
+	The System.Web classes are now part of the build (and they are
+	also part of the class status now).  Ajay contributed a large
+	chunk of code to the System.Xml.Schema namespace
+
+	Dan (of regex fame) has been working on internal calls
+	support: moving more code from the old monowrapper to become
+	internal calls.
+

+
+	The JIT engine can now run all the compiler regression tests as

+	allocator (just enough to allow us to focus on feature completeness)
+	and that will be the next major task to improve performance and
+	reduce spills and reloads. 
+
+	On the C# compiler front: language features are now pretty
+	much complete.  The big missing tasks are unsafe code support,
+	visibility, explicit interface implementation plus static flow
+	analysis.  There are many small bugs that need to be addressed.

+<ul>
+		* The C# compiler is being worked on and can compile

+
+		* The class libraries need to be mature enough to support

+
+	  	  The compiler currently requires 103 classes from the

+* Java
+
+	It would be interesting to support the Java language as part
+	of the Mono project.  
+
+	You have to think of Java as various pieces: Java the
+	language and Java the virtual machine.  
+
+	It is possible to compile Java to .NET, as shown by the
+	Microsoft J# compiler.   We could then allow the migration of
+	Java applications to the Mono runtime. 
+
+** Native compiler
+
+	Although a native compiler can be built, and probably should be
+	built using an existing compiler, a short term solution is to 
+	build a translator from Java class files to the ECMA CIL images.
+
+	This has the advantage that we can use an existing and tested
+	Java compiler to generate the code, and then we can use an automated
+	code compiler that compiles Java VM bytecodes to CIL bytecodes.
+
+** The translator.
+
+	It would be interesting to write a semantic translator that
+	converts java byte codes into CIL opcodes.  This is possible
+	because the Java byte codes are a subset of the CIL ones.
+
+	A semantic tree needs to be constructed (very much in the
+	spirit of what is done in mono_analize_stack in
+	<tt>mono/mono/jit/jit.c</tt>.  Once such a semantic tree is
+	constructed, we could generate the equivalent Java code.
+
+	This has a number of interesting side effects: people can
+	continue to use their existing Java compilers to compile their
+	code, and a simple tool that converts their .class files into
+	a .NET assembly can be used.
+
+** Libraries
+
+	We could translate the GNU Classpath libraries with the above
+	tools to provide the Java runtime required to host into the
+	Mono runtime.  Some special treatment would be required for
+	core data types like integers, arrays and strings, and of
+	course reuse where possible existing classes from .NET to make
+	them compatible.
+
+** JILC - Java to IL Compiler
+
+	This is an attempt to make the java bytecode available for the
+	.NET environment.
+
+	The project attempts to generate the IL code / bytecode from the
+	compiled java class files. It has reached the stage of code-generation.
+	The issues that needs to be addressed is the mapping of java objects
+	to the IL objects, eg: java.lang.String to System.String.
+
+	Gaurav Vaish and Abhaya Agarwal are currently leading this project.
+	The project is currently hosted at <a href="http://sourceforge.net/projects/jilc">SourceForge.Net</a>.
+	The official home page of the project is 
+	<a href="http://jilc.sourceforge.net">http://jilc.sourceforge.net</a>.

+* How to debug your C# application with the JIT engine 
+
+	To debug a C# application you need to run the JIT in your debugger.
+
+	Before you can do anything useful in a debugger, you need a symbol
+	file which tells your debugger about functions, types, line numbers
+	and such. Unfortunately, this symbol file needs to be recreated each
+	time the JIT compiles a new method since it doesn't know anything
+	about this method (especially not its memory address) before actually
+	compiling it.
+
+	You have two ways of creating a symbol file:
+
+** Letting the JIT dynamically create the symbol file
+
+	This'll give you a symbol file which is suitable for debugging IL byte
+	code - you won't see your C# source code.
+
+	However, this method has the advantage that it works with every assembly,
+	no matter whether it has been compiled with Mono's C# compiler (MCS) or
+	with any other compiler. It's currently the only way to debug
+	<tt>corlib.dll</tt> or any other library which cannot be compiled with
+	our compiler yet.
+
+	All that you need is a dump of the IL bytecode for each assembly (including
+	all assemblies this assembly is referencing). This is done by using the
+	<tt>monodis</tt> utility:
+
+	<pre>
+	monodis /home/export/martin/MONO-LINUX/lib/corlib.dll > corlib.il<br>
+	monodis /home/export/martin/MONO-LINUX/lib/System.dll > System.il<br>
+	monodis /home/export/martin/MONO-LINUX/bin/mcs.exe > mcs.il
+	</pre>
+
+	Make sure that all the .il files have the same name as their corresponding
+	assembly and that they're all created in the current directory.
+
+	The JIT supports two different debugging file formats:
+
+	<ul>
+	* STABS: This is a very simple debugging format, but it may be the only one
+	which is supported on your system. It is limited to source files of no more
+	than 65.535 lines and it's type support is also very limited. You should only
+	use this if your debugger doesn't support DWARF 2.
+
+	To generate STABS output, use the <tt>--stabs</tt> command line argument.
+
+
+	* DWARF 2: The DWARF 2 debugging format is a very powerful debugging format
+	which can handle source files of arbitrary size and has a highly sophisticated
+	type support. It's the recommended format unless you need to use STABS because
+	your debugger doesn't support DWARF 2.
+
+	To generate DWARF 2 output, use the <tt>--dwarf</tt> command line argument.
+	</ul>
+
+
+	You need to regenerate the symbol file each time the JIT compiled a new
+	method and each time you restart the JIT. You cannot reuse your symbol file
+	if you start the JIT a second file, not even if you're running the same
+	application with the same input data a second time.
+
+	Regenerating the symbol file is done by calling the JIT's
+	<tt>mono_debug_make_symbols ()</tt> function from within your debugger and
+	then reloading the symbol files. This function creates a <tt>filename-dwarf.s</tt>
+	(or <tt>filename-stabs.s</tt>) assembler input file in the current directory and
+	an object file in <tt>/tmp/filename.o</tt> - you need to tell your debugger to
+	add this object file as symbol file.
+
+	If you're using the GNU debugger, this is done like this:
+
+	<pre>
+	call mono_debug_make_symbols ()
+	add-symbol-file /tmp/corlib.o
+	add-symbol-file /tmp/mcs.o
+	add-symbol-file /tmp/Mono.CSharp.Debugger.o
+	</pre>
+
+	You can also write a GDB macro like this:
+
+	<pre>
+	define reload
+	  call mono_debug_make_symbols ()
+	  add-symbol-file /tmp/corlib.o
+	  add-symbol-file /tmp/mcs.o
+	  add-symbol-file /tmp/Mono.CSharp.Debugger.o
+	end
+	</pre>
+
+	Then you can just say <tt>reload</tt> to have GDB recreate the symbol file.
+
+	There's also an <a href="jit-debug-sample.html">example debugging session</a> using
+	the GNU debugger.
+
+** Using a symbol file which have been created by the Mono C# compiler
+
+	If you compiled your application with Mono's C# compiler (MCS), you can tell it to
+	create a symbol file which is then processed and rewritten by the JIT engine.
+
+	To do this, you must give MCS the <tt>-g</tt> option:
+
+	<pre>
+	$ mcs -g Foo.cs
+	</pre>
+
+	This creates a <tt>Foo-debug.s</tt> assembler input file.
+
+	To use this in the JIT, you must first copy it to the target machine (the machine
+	where you want to run the JIT to debug your application) and run it through the
+	assembler to produce an object file <tt>Foo-debug.o</tt>. This object file must be
+	in the current directory.
+
+	Then start the JIT in your debugger and give it the <tt>--dwarf-plus</tt> command
+	line argument.
+
+	Each time you call <tt>mono_debug_make_symbols ()</tt> from withing your debugger,
+	the JIT will read this <tt>Foo-debug.o</tt>, fix some machine dependent things like
+	memory addresses etc. in it and write it back to disk.
+
+	If you're using the GNU debugger, you'll want to use a macro like this:
+
+	<pre>
+	define relocate
+	  call mono_debug_make_symbols ()
+	  add-symbol-file /tmp/corlib.o
+	  add-symbol-file mcs-debug.o
+	  add-symbol-file Mono.CSharp.Debugger-debug.o
+	end
+	</pre>
+
+	If there is no <tt>assembly-debug.o</tt> file, but an <tt>assembly.il</tt> one, the
+	JIT will fall back to normal DWARF 2 (in the example above, <tt>corlib.dll</tt> was
+	compiled with Microsoft's compiler and the JIT is thus using DWARF to debug it).
+
+	This debugging method only works if you compiled your assembly with MCS, but it'll
+	allow you to actually debug your C# source code :-)
+
+	Here's an <a href="jit-debug-sample2.html">example debugging session</a> using
+	the GNU debugger.
+
+** Breakpoints and single stepping
+
+	The JIT has a <tt>--debug</tt> command line argument to insert a breakpoint at the
+	beginning of this method. It takes a <tt>Namespace.Class:Method</tt> argument which
+	is the method. This argument can be given multiple times.
+
+	However, once your application is stopped in GDB you may want to insert a breakpoint
+	the next time the JIT compiles a method. There's a global variable
+	<tt>mono_debug_insert_breakpoint</tt> which you can modify in your debugger.
+
+	If this variable is set to a non-zero value, the JIT's <tt>arch_compile_method</tt>
+	will insert a breakpoint the next time it is called, ie. at the top of the next
+	method it compiles. If this value has a positive value, it acts as a counter and is
+	decremented after inserting the breakpoint - setting it to a negative value will let
+	the JIT insert the breakpoint each time it compiles a new method.
+
+	There's also global variable <tt>mono_debug_last_breakpoint_address</tt> which always
+	contains the address of the last inserted breakpoint. You may manually override this
+	address with a <tt>nop</tt> instruction to delete the breakpoint.
+
+	For instance, I have a GDB macro called <tt>enter</tt> which I use to enter a method
+	rather than stepping over it:
+
+	<pre>
+	define enter
+	set mono_debug_insert_breakpoint = 1
+	continue
+	set *mono_debug_last_breakpoint_address = 0x90
+	relocate
+	frame
+	</pre>
+
+	Btw. speaking of single stepping - you should use your debuggers <tt>next</tt> command,
+	not its <tt>step</tt> command for single stepping unless you compiled the JIT without
+	debugging support. The reason for this is that the JIT creates machine code which contains
+	calls to JIT methods such as <tt>mono_object_new_wrapper</tt> at places where you don't
+	expect them - so unless the JIT is compiled at least without line numbers, your debugger
+	will enter such methods if you use <tt>step</tt> rather than <tt>next</tt>.

+* A debugging session using a symbol file which has been created by MCS.
+
+	Let's assume we have the following C# application which we want to debug:
+
+	<pre>
+	using System;
+
+	public class Foo
+	{
+		public struct MyStruct {
+			int a;
+			long b;
+			double c;
+		}
+
+		public static void Main ()
+		{
+			Int32 value = 5;
+			long test = 512;
+
+			MyStruct my_struct;
+			my_struct.a = 5;
+			my_struct.b = test;
+			my_struct.c = 23323.5235;
+		}
+	}
+	</pre>
+
+	First of all, we need to compile it with MCS, assemble the generated .s file and
+	create the .il files for all referenced assemblies which were not compiled with MCS:
+
+	<pre>
+	$ mcs -g ./Foo.cs
+	$ as -o Foo-debug.o Foo-debug.s
+	$ monodis /home/export/martin/MONO-LINUX/lib/corlib.dll > corlib.il
+	</pre>
+
+	Now we can start the JIT in the debugger:
+
+	<pre>
+	$ gdb ~/monocvs/mono/mono/jit/mono
+	(gdb) r --dwarf-plus --debug Foo:Main ./Foo.exe
+	Starting program: /home/martin/monocvs/mono/mono/jit/mono --dwarf-plus --debug Foo:Main ./Foo.exe

+
+	You could port this code from Java to C#.

+	runtime.
+
+<a name="c">
+* C
+
+	Ideally GCC could be modified to generate CIL, but it is a 
+	big task.  That would give us various compilers in one pass.
+
+	Rumor is that the next version of the LCC compiler will
+	include an IL backend.  We do not know how extensive the support
+	for integration with .NET will be, but it would be an interesting
+	excercise to add an extension to C to call into .NET code.
+
+	LCC is not an open source compiler, but it is free as long as you
+	do not profit from selling it.

+<para>
+Mono is an open source implementation of the Common Language Infrastructure
+(CLI) specified in ECMA standard 335. It comes with a C# compiler and
+provides an extensible platform to develop and run applications that
+are interoperable with Microsoft .NET.
+</para>
+
+<para>
+Mono is not finished--it is a project still under development. As a
+result, installation and configuration may not be as smooth as you
+will be used to from other Linux applications. Nevertheless, mono is
+in a state that will allow you to get it up and running and gain
+experience with it--which is, I would suggest, a very smart thing to do.
+</para>
+
+<para>
+This document is limited in the following sense: it describes how to
+download a 'stable' version of mono as a 'tarball' and get it to run on
+your computer. I'm also assuming you run mono on Linux rather than
+on Windows. All the examples have been tested on a 'vanilla' Red Hat 7.3 
+installation.
+</para>
+
+<para>
+There are two items this document will <emphasis>not 
+</emphasis> cover: the first is how to self host the mcs compiler 
+under linux and the second is the graphical user environment 
+which is implemented as GTK#. These two interesting topics 
+are the subject of two more howto's that I'm planning.
+</para>
+
+<para>
+This document is also less useful for two types of people.
+</para> 
+<itemizedlist> 
+<listitem> 
+<para> 
+If you are a very inexperienced linux user and want to know what mono is
+all about, there is an easier way to install mono. Go to mono.baselabs.org
+and download the rpm's ready for installation on your system. This site also
+runs a tutorial that is worth reading.
+</para> 
+</listitem> 
+<listitem> 
+<para> 
+If you are a very experienced user wanting to contribute to the mono code,
+you should probably regularly do a CVS download. At the moment, the mono
+code grows very fast, and the 'stable' releases still appear too slowly.
+</para>
+</listitem>
+
+</itemizedlist>
+
+<para>
+This document is aimed at the mono beginner, and aims to present a complete
+view of a minimal installation, which will allow you to experiment with
+mono to some degree. It also describes some of those experiments. We
+expect that after reading this document you'll go on to do either of
+two things:
+</para>
+<orderedlist>
+<listitem>
+<para>
+Continue to contribute to the mono project in some shape or form. The
+website has some ideas and suggestions under the heading 'Contributing'.
+</para>
+</listitem>
+<listitem>
+<para>
+Continue to write applications that run in mono.

+<para> 
+There are several ways to get Mono running on your computer. This
+document will discuss only one of those: downloading the source tarball
+and utilising the make utilities to get mono up and running.  There is
+only one mono package to worry about if you are just after a 'base' install
+of mono: the mono runtime. This package, found under the name "mono-x.xx"
+has got a compiled version of the compiler built in.
+</para>
+
+<para>
+You'll be able to complete everything in this document if you just install
+the runtime, but taking a look at the compiler package is well worth the
+effort. The compiler is written in C# and is 'self hosting' which means it
+is able to compile itself. 
+</para>
+
+<para>
+As of this moment, it is my understanding that there are still some issues
+with the 'self hosting' bit of the compiler on linux, although this is 
+expected to work in later versions of mono. If you are just interested in
+finding out how mono will work under linux, I would not worry about the
+self-hosting bit for now. The self-hosting of the compiler will be the
+topic of a future howto.
+</para>
+
+<para> 
+See <ulink url="http://www.go-mono.com/download">the mono download
+site</ulink> for the source of the tarballs.  
+</para>
+
+<para>
+This page also lists the current versions of the software 
+mono depends on. Make sure that your system has all the 
+required versions, otherwise mono won't compile.
+</para>

+At a minimum for mono 0.12, you'll need to:

+
+<para> 
+Installing the tarballs is done via GNU autoconf and
+automake. The general upshot of running autoconf and automake is that you
+can type <command>./configure</command> and then <command> make</command>
+to do the build.  
+Typing <command>make install</command> completes the installation of mono
+on your system.
+</para>
+
+<para>
+To build the mono runtime package, unzip the tarball to some useful
+location.  I tend to use <command>/usr/src</command> as the location,
+but you could really do it anywhere. For the install process, it is
+also a good idea to be 'root'.  The installation process will shuttle
+some executables into <command>/usr/local/bin</command> (more about
+that later).
+</para>
+
+<para>
+Unzipping the tarballs will have created two directories in <command>
+/usr/src/</command>, one called something like mono-x.xx and the other 
+mcs-x.xx. The one called 'mono' is the runtime environment, and this contains
+all that is initially needed to run mono and investigate its inner workings.
+</para>
+
+<para>
+To start building the mono runtime, first type <command>./configure</command>.

+To finally install mono, you can type <command>make install</command> 
+to get a working version of mono. This command will copy the

+<sect2 id="garbage_collection">
+<title> Garbage Collection</title>
+<para>
+To make the mint interpreter work with garbage collection, you first need to
+install a garbage collection package on your system. Mono works with
+Boehm Garbage collection, which is found at 
+<ulink url="http://www.hpl.hp.com/personal/Hans_Boehm/gc/">
+http://www.hpl.hp.com/personal/Hans_Boehm/gc/
+</ulink>.
+</para>
+
+<para>
+To get garbage collection to work, I downloaded the source tarball 
+into <command>/usr/src/</command> and typed <command>./configure</command>
+followed by <command>make</command> and <command>make install</command>.
+</para>
+
+<para>
+There is one glitch to work around. The header file for the garbage collection
+<command>gc.h</command> is found in the <command>/usr/src/gc6.0/include
+</command> directory (at least on my system). The mono build process will break
+on this location: it is looking for the header file in some other place called
+<command>/usr/include/gc/</command> and won't be able to find the correct
+header file.
+</para>
+
+<para>
+The solution is to build a symbolic link between these two locations as 
+follows
+</para>
+
+<programlisting>
+[root@taurus include]# ln -s /usr/src/gc6.0/include/ /usr/include/gc
+</programlisting>
+

+To work with mono, you first have to create a C# program. Open up

+<programlisting>
+using System;
+
+class Hello
+{
+public static void Main(String[] args)
+	{

+	}
+}

+Save the file as hello.cs. To compile this into a working program,

+you know the compile worked fine. If you see some strange error
+messages including the word 'parser' somewhere, you made a mistake in
+your program. Fix this up first.
+</para>
+
+<para>
+You are now ready to execute your first mono program.  To execute 
+the code, type
+</para>
+
+<programlisting>
+[hinne@taurus hello]$ mono hello.exe arg1 arg2 arg 3
+</programlisting>
+<para>
+(where we have given some arguments just for fun) and you'll 
+see the following:
+</para>
+
+<programlisting>
+mono:: is alive and well...
+Argument 0 = arg1
+Argument 1 = arg2
+Argument 2 = arg
+Argument 3 = 3
+RESULT: 0
+</programlisting>
+<para>
+As you can see, mono printed the line "mono:: is alive and well" 
+and printed the list of arguments. This completes the creation 
+and execution of your first mono program.
+</para>
+</sect2>
+
+<sect2 id="interpreter">
+<title>Interpreter</title>
+<para>
+But mono will allow you to do more. First of all, mono is the 
+compiled mono execution environment which uses the Just in 
+Time (JIT) compiler. Mono also comes with an interpreted 
+environment, which can be accessed using the command 'mint' 
+as follows
+</para>
+<programlisting>
+[hinne@taurus hello]$ mint hello.exe arg1 arg 2
+mono:: is alive and well...
+Argument 0 = arg1
+Argument 1 = arg
+Argument 2 = 2
+[hinne@taurus hello]$
+</programlisting>
+<para>
+As you can see, it makes no difference to mono output which 
+environment you use, but what happens under the hood is very 
+different. If you use 'mono' as the command line tool, you 
+call the 'production' execution environment which will read 
+your portable executable (PE) file, and call the just in 
+time (JIT) compiler to compile the PE code down to machine 
+level code (in my case, an x86 architecture) after which 
+it is executed.
+</para>
+<para>
+If you use mint, the JIT is not used, and the PE code is 
+interpreted into x86 instructions for execution. In fact, 
+for our simple 'hello' mint is slightly faster. The point 
+is that the JIT compiler will take some time to compile the 
+code of our program and store it in some location in memory, 
+but the subsequent execution of the code is faster with mono.
+</para>
+<para>
+
+You can see what happens below (the thing to look for is the 
+'user' time: 0.1 seconds with mono and 0.06 seconds with mint):
+
+</para>
+<programlisting>
+[hinne@taurus hello]$ time mono hello.exe arg1 arg 2

+After this simple run of mono, it is time to play with some options.

+Mono supports a debugging option when you specify the "-d" flag while running
+the runtime. Utilising this flag will get you a significant amount of output,
+and it may be an idea to specify an output file as well. The interesting aspect

+
+<para>The purpose of this License is to make a manual, textbook,
+    or other written document "free" in the sense of freedom: to assure
+    everyone the effective freedom to copy and redistribute it, with
+    or without modifying it, either commercially or noncommercially.
+    Secondarily, this License preserves for the author and publisher
+    a way to get credit for their work, while not being considered
+    responsible for modifications made by others.</para>
+
+<para>This License is a kind of "copyleft", which means that
+    derivative works of the document must themselves be free in the
+    same sense.  It complements the GNU General Public License, which
+    is a copyleft license designed for free software.</para>
+
+<para>We have designed this License in order to use it for manuals
+    for free software, because free software needs free documentation:
+    a free program should come with manuals providing the same freedoms
+    that the software does.  But this License is not limited to software
+    manuals; it can be used for any textual work, regardless of subject
+    matter or whether it is published as a printed book.  We recommend
+    this License principally for works whose purpose is instruction
+    or reference.</para>
+</sect3>
+
+<sect3 id="gfdl-1"> <title>APPLICABILITY AND DEFINITIONS</title>
+
+<para>This License applies to any manual or other work that
+    contains a notice placed by the copyright holder saying it can be
+    distributed under the terms of this License.  The "Document", below,
+    refers to any such manual or work.	Any member of the public is a
+    licensee, and is addressed as "you".</para>
+
+<para>A "Modified Version" of the Document means any work
+    containing the Document or a portion of it, either copied verbatim,
+    or with modifications and/or translated into another language.</para>
+
+<para>A "Secondary Section" is a named appendix or a front-matter
+    section of the Document that deals exclusively with the relationship
+    of the publishers or authors of the Document to the Document's overall
+    subject (or to related matters) and contains nothing that could fall
+    directly within that overall subject.  (For example, if the Document
+    is in part a textbook of mathematics, a Secondary Section may not
+    explain any mathematics.)  The relationship could be a matter of
+    historical connection with the subject or with related matters, or
+    of legal, commercial, philosophical, ethical or political position
+    regarding them.</para>
+
+<para>The "Invariant Sections" are certain Secondary Sections
+    whose titles are designated, as being those of Invariant Sections,
+    in the notice that says that the Document is released under this
+    License.</para>
+
+<para>The "Cover Texts" are certain short passages of text that
+    are listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+    that says that the Document is released under this License.</para>
+
+<para>A "Transparent" copy of the Document means a
+    machine-readable copy, represented in a format whose specification
+    is available to the general public, whose contents can be viewed and
+    edited directly and straightforwardly with generic text editors
+    or (for images composed of pixels) generic paint programs or
+    (for drawings) some widely available drawing editor, and that is
+    suitable for input to text formatters or for automatic translation
+    to a variety of formats suitable for input to text formatters.
+    A copy made in an otherwise Transparent file format whose markup
+    has been designed to thwart or discourage subsequent modification
+    by readers is not Transparent.  A copy that is not "Transparent"
+    is called "Opaque".</para>
+
+<para>Examples of suitable formats for Transparent copies include
+    plain ASCII without markup, Texinfo input format, LaTeX input format,
+    SGML or XML using a publicly available DTD, and standard-conforming
+    simple HTML designed for human modification.  Opaque formats include
+    PostScript, PDF, proprietary formats that can be read and edited
+    only by proprietary word processors, SGML or XML for which the
+    DTD and/or processing tools are not generally available, and the
+    machine-generated HTML produced by some word processors for output
+    purposes only.</para>
+
+<para>The "Title Page" means, for a printed book, the title page
+    itself, plus such following pages as are needed to hold, legibly,
+    the material this License requires to appear in the title page.
+    For works in formats which do not have any title page as such,
+    "Title Page" means the text near the most prominent appearance of the
+    work's title, preceding the beginning of the body of the text.</para>

+<sect3 id="gfdl-2"> <title>VERBATIM COPYING</title>
+

+    either commercially or noncommercially, provided that this License,
+    the copyright notices, and the license notice saying this License
+    applies to the Document are reproduced in all copies, and that
+    you add no other conditions whatsoever to those of this License.
+    You may not use technical measures to obstruct or control the
+    reading or further copying of the copies you make or distribute.
+    However, you may accept compensation in exchange for copies.  If you
+    distribute a large enough number of copies you must also follow the
+    conditions in section 3.</para>
+
+<para>You may also lend copies, under the same conditions stated
+    above, and you may publicly display copies.</para>

+
+<sect3 id="gfdl-3"> <title>COPYING IN QUANTITY</title>
+
+<para>If you publish printed copies of the Document numbering more
+    than 100, and the Document's license notice requires Cover Texts, you
+    must enclose the copies in covers that carry, clearly and legibly,
+    all these Cover Texts: Front-Cover Texts on the front cover, and
+    Back-Cover Texts on the back cover.  Both covers must also clearly
+    and legibly identify you as the publisher of these copies.	The front
+    cover must present the full title with all words of the title equally
+    prominent and visible.  You may add other material on the covers
+    in addition.  Copying with changes limited to the covers, as long as
+    they preserve the title of the Document and satisfy these conditions,
+    can be treated as verbatim copying in other respects.</para>
+
+<para>If the required texts for either cover are too voluminous to
+    fit legibly, you should put the first ones listed (as many as fit
+    reasonably) on the actual cover, and continue the rest onto adjacent
+    pages.</para>
+
+<para>If you publish or distribute Opaque copies of the Document
+    numbering more than 100, you must either include a machine-readable
+    Transparent copy along with each Opaque copy, or state in or with each
+    Opaque copy a publicly-accessible computer-network location containing
+    a complete Transparent copy of the Document, free of added material,
+    which the general network-using public has access to download
+    anonymously at no charge using public-standard network protocols.
+    If you use the latter option, you must take reasonably prudent steps,
+    when you begin distribution of Opaque copies in quantity, to ensure
+    that this Transparent copy will remain thus accessible at the stated
+    location until at least one year after the last time you distribute
+    an Opaque copy (directly or through your agents or retailers) of
+    that edition to the public.</para>
+
+<para>It is requested, but not required, that you contact the
+    authors of the Document well before redistributing any large number
+    of copies, to give them a chance to provide you with an updated

+    Replacing Invariant Sections with translations requires special
+    permission from their copyright holders, but you may include
+    translations of some or all Invariant Sections in addition to the
+    original versions of these Invariant Sections.  You may include
+    a translation of this License provided that you also include the

+
+<sect3 id="gfdl-9"> <title>TERMINATION</title> <para>You may not copy,
+modify, sublicense, or distribute the
+    Document except as expressly provided for under this License.
+    Any other attempt to copy, modify, sublicense or distribute the
+    Document is void, and will automatically terminate your rights under

+			<Mono newbie coders start file>
+	<h1> A little help for mono newbie coders </h1>
+
+
+	For those who are new to Mono and are impatient to contribute
+	with code (uhh... you are brave!!) here is the document you 
+	should read.
+
+	
+	You will see all Mono hackers say the same (great minds have
+	similar way of thinking): First, DO WRITE TESTS!!!. In order
+	to do that:
+	
+	<ul>
+		* Start with the NUnit Tests Guidelines.  In the cvs
+	    	  they are located at: mcs/class/doc/NUnitGuideli...
+
+		* But wait, this is a document for impatient
+	    	  people. So EVERYTHING should be here. Well, it is. 
+	</ul>
+
+
+	<h2> The NUnit Tests Guidelines document </h2>
+
+	Mono NUnit Test Guidelines and Best Practices
+
+	Authors: Nick Drochak  <ndrochak@gol.com>
+	Martin Baulig  <martin@gnome.org>
+	Last Update: 2002-03-02
+	Rev: 0.3
+
+ <b> Purpose </b>
+
+	This document captures all the good ideas people have had 
+	about writing NUnit tests for the mono project. This document 
+	will be useful for anyone who writes or maintains unit tests.
+
+ <b> Other resources </b>
+
+	- mcs/class/README has an explanation of the build process and
+	  how it relates to the tests.
+	- http://nunit.sourceforge.net is the place to find out about 
+	  NUnit
+
+ <b> Getting Started </b>
+
+	If you are new to writing NUnit tests, there is a template 
+	you may use to help get started. The file is:
+
+	mcs/class/doc/TemplateTest.cs
+
+
+	(2.- This is the point two!. This file is just after the end 
+	of the guidelines. Copy/paste it in another buffer. And keep 
+	reading.)
+
+	Save a copy of this file in the appropriate test subdirecty 
+	(see below), and replace all the [text] markers with 
+	appropriate code. Comments in the template are there to guide 
+	you. You should also look at existing tests to see how other 
+	people have written them. 
+
+	mcs/class/corlib/Test/System.Collections/CollectionBaseTest.cs 
+
+	is a small one that might help.
+
+	(3.- You reached the third point. And as expected, it's just 
+	here to tell you that the content of CollectionBaseTest.cs is 
+	after the TemplateTest.cs code at the end of these 
+	guidelines.)
+
+	The directory that will contain your new file depends on the
+	assembly/namespace of the class for which you are creating the
+	tests. Under mcs/class there is a directory for each assembly. 
+	In each assembly there is a Test directory, e.g. 
+	mcs/class/corlib/Test. In the Test directory there are 
+	sub-directories for each namespace in the assembly, e.g. 
+	mcs/class/corlib/Test/Sytem. Put your new test file in the 
+	appropriate sub-directory under Test for the class you are
+	testing.
+
+	Once your test class is complete, you need to add it to the
+	AllTests.cs file in the same directory as your new test. Add a 
+	call to "suite.AddTest()" passing the name of your new test 
+	class's suite property as the parameter.  You will see examples 
+	in the AllTests.cs file, so just copy and paste inside there.
+
+	Once all of that is done, you can do a 'make test' from the top 
+	mcs directory.  Your test class will be automagically included 
+	in the build and the tests will be run along with all the 
+	others.
+
+ <b> Tips </b>
+
+ <b> Provide an unique error message for Assert() </b>
+
+	Include an unique message for each Assert() so that when the 
+	assert fails, it is trivial to locate the failing one. 
+	Otherwise, it may be difficult to determine which part of the 
+	test is failing. A good way to ensure unique messages is to use 
+	something like #A01, #A02 etc.
+
+    	Bad:
+<pre>
+	AssertEquals("array match", compare[0], i1[0]);
+	AssertEquals("array match", compare[1], i1[1]);
+	AssertEquals("array match", compare[2], i1[2]);
+	AssertEquals("array match", compare[3], i1[3]);
+</pre>
+    	Good:
+<pre>
+	AssertEquals("#A01", compare[0], i1[0]);
+	AssertEquals("#A02", compare[1], i1[1]);
+	AssertEquals("#A03", compare[2], i1[2]);
+	AssertEquals("#A04", compare[3], i1[3]);
+</pre>
+	Once you used such a number in an Assert(), don't change it 
+	later on - people might use it it identify the test in bug 
+	reports or in mailing lists.
+
+ <b> Use AssertEquals() to compare things, not Assert(). </b>
+
+	Never compare two values with Assert() - if the test fails, 
+	people have no idea what went wrong while AssertEquals() 
+	reports the failed value.
+
+    	Bad:
+<pre>
+        Assert ("A01", myTicks[0] == t1.Ticks);
+</pre>
+    	Good:
+<pre>
+        AssertEquals ("A01", myTicks[0], t1.Ticks);
+</pre>
+
+ <b> Constructors </b>
+
+	When writing your testcase, please make sure to provide a 
+	constructor which takes no arguments:
+
+<pre>
+        public class DateTimeTest : TestCase
+        {
+
+                public DateTimeTest() : base ("[MonoTests.System.DateTimeTest]") {}
+                public DateTimeTest (string name): base(name) {}
+
+        	public static ITest Suite
+                {
+                        get {
+                                TestSuite suite = new TestSuite ();
+        			return suite;
+        		}
+        	}
+        }
+</pre>
+
+ <b> Namespace </b>
+
+	Please keep the namespace within each test directory
+	consistent - all tests which are referenced in the same
+	AllTests.cs must be in the same namespace. Of course you can
+	use subnamespaces as you like - especially for subdirectories
+	of your testsuite.
+	
+	For instance, if your AllTests.cs is in namespace "MonoTests"
+	and you have a subdirectory called "System", you can put all
+	the tests in that dir into namespace "MonoTests.System".
+
+ <b> Test your test with the microsoft runtime </b>
+
+	If possible, try to run your testsuite with the Microsoft
+	runtime on Windows and make sure all tests in it pass. This is
+	especially important if you're writing a totally new testcase
+	- without this check you can never be sure that your testcase
+	contains no bugs ....
+	
+	Don't worry if you're writing your test on Linux, other people
+	can test it for you on Windows.
+	
+	Sometimes you may discover that a test doesn't show the
+	expected result when run with the Microsoft runtime - either
+	because there is a bug in their runtime or something is
+	misleading or wrong in their documentation. In this case,
+	please put a detailed description of the problem to
+	mcs/class/doc/API-notes and do also report it to the list -
+	we'll forward this to the Microsoft people from time to time
+	to help them fix their documentation and runtime.

+* MonoDoc XML Tag Reference
+
+** Introduction
+
+<em>
+[This documentation is in progress.  Comments to
+<a href="mailto:jbarn@httcb.net">jbarn@httcb.net</a> and/or
+<a href="mailto:mono-docs-list@ximian.com">mono-docs-list@ximian.com</a>.]
+</em>
+
+MonoDoc XML, our format for multilingual API documentation stored outside of
+source files, is very similar to the output of Microsoft's csc /doc.  Minor
+alterations have been made to ease human parsing and hand-editing, but
+the majority of the tags are identical.  In fact, many of the descriptions
+and examples below are taken from the ECMA C# Language Specification with
+little or no alteration.
+
+This document provides a list of all available MonoDoc XML tags, with
+syntax and examples.  A complete example can be found in
+<a href="#appendix-a">Appendix A</a>, and both a <a href="#">DTD</a> and
+<a href="#">XSD schema</a> will be available very shortly.

+** Definitions and Examples
+
+*** <a name="c">&lt;c&gt;</a>
+
+This tag can be used to mark short, inline fragments of text that should 
+be considered source code or program output.  User agents should render 
+this tag in a special -- likely monospace -- font.  For larger sections, 
+use <a href="#code"><code>&lt;code&gt;</code></a>.
+
+**** Syntax
+
+<pre>
+&lt;c&gt;code or output text&lt;/c&gt;
+</pre>
+
+**** Example
+
+<pre>   
+&lt;remarks&gt;
+    Class &lt;c&gt;Point&lt;/c&gt; models a point in two-dimensional space.
+&lt;/remarks&gt;
+</pre>
+
+*** <a name="code">&lt;code&gt;</a>
+
+This tag can be used to mark one or more lines of text as source code or 
+program output.  User agents should render this tag in a special (likely 
+monospace) font, and preserve both whitespace and newlines.
+
+**** Syntax
+
+	<code>&lt;code&gt;source or program output&lt;/code&gt;</code>
+
+**** Example
+
+<pre>
+&lt;summary&gt;
+    This method changes the point's location by the given
+    x- and y-offsets.
+    &lt;example lang="C#"&gt;
+        A C# example:
+        &lt;code&gt;
+            Point p = new Point(3, 5);
+            p.Translate(-1, 3);
+            // p == (2, 8);
+        &lt;/code&gt;
+    &lt;/example&gt;
+&lt;/summary&gt;
+</pre>
+
+*** <a name="doc">&lt;doc&gt;</a>
+
+This tag is the root element of the documentation file.  It can contain 
+any number of &lt;type&gt; elements.
+
+**** Syntax
+
+<code>&lt;doc lang="language" assembly="assembly"&gt;typedocs&lt;/doc&gt;</code>
+
+<blockquote>
+<em>lang="language"</em><br />
+The two-letter ISO code that specifies what language the contained
+documentation is written in.
+</blockquote>
+
+**** Example
+
+<pre>
+&lt;doc lang="en"&gt;
+    &lt;type name="Graphics.Point"&gt;
+        &lt;!-- ... --&gt;
+    &lt;/type&gt;
+&lt;/doc&gt; 
+</pre>
+
+*** <a name="event">&lt;event&gt;</a>
+
+This tag documents an event.

+
+<blockquote>
+<em>name="eventname"</em><br />
+The name of the event being documented.
+</blockquote>
+		
+**** Example
+
+<pre>
+&lt;event name="Click"&gt;
+    &lt;summary&gt;
+        Occurs when the control is clicked.
+    &lt;/summary&gt;
+    &lt;data&gt;
+        The event handler receives an argument of type EventArgs
+        containing data related to this event.
+    &lt;/data&gt;
+    &lt;remarks&gt;
+        &lt;para&gt;The ControlStyles.StandardClick style must be set 
+        for this event to be raised.&lt;/para&gt;
+        &lt;para&gt;For more information about handling events, see 
+        Consuming Events.&lt;/para&gt;
+    &lt;/remarks&gt;
+&lt;/event&gt;
+</pre>
+
+*** <a name="example">&lt;example&gt;</a>
+
+This tag marks a section of text as an example, and optionally specifies 
+what programming language <code><a href="#code">&lt;code&gt;</a></code> portions of the example are written in.
+
+**** Syntax
+
+<code><example lang="language">example text and code</example></code>
+
+<blockquote>
+<em>lang="language"</em><br />
+(optional) The name of the programming language <code><a href="#code">&lt;code&gt;</a></code> blocks in this example
+use.  This information can be used by user agents to provide
+intelligent access to examples in multiple languages.

+
+<blockquote>
+<em>cref="exception-type"</em><br />
+The name of an exception type.
+</blockquote>
+
+**** Example

+	x-coordinate.
+    &lt;/summary&gt;
+&lt;/field&gt;
+</pre>
+
+*** <a name="list">&lt;list&gt;</a>
+
+This tag is used to create a list or table of items.  It may contain a 
+<code>&lt;listheader&gt;</code> block to define the heading row of either a table or 
+definition list.  (When defining a table, only an entry for 'term' in the 
+heading need be supplied.)
+
+Each item in the list is specified with an <code>&lt;item&gt;</code> block.  When creating a 
+definition list, both <code>&lt;term&gt;</code> and <code>&ltdescription&gt;</code> must be specified.  
+However, for a table, bulleted list, or numbered list, only <code>&lt;description&gt;</code>
+need be specified.
+
+**** Syntax
+
+<pre>
+&lt;list type="bullet" | "number" | "table"&gt;
+   &lt;listheader&gt;
+       &lt;term&gt;term&lt;/term&gt;
+       &lt;description&gt;description&lt;/description&gt;

+The term to define, whose definition is in <code>&lt;description&gt;</code>.
+<br /><br />	
+<em>description</em><br />
+Either an item in a bullet or numbered list, or the definition of a <code>&lt;term&gt;</code>.
+</blockquote>
+
+**** Example
+
+<pre>
+&lt;list type="bullet"&gt;
+    &lt;item&gt;
+        &lt;description&gt;Item 1&lt;/description&gt;

+    &lt;item&gt;
+        &lt;description&gt;Item 2&lt;/description&gt;
+    &lt;/item&gt;
+&lt;/list&gt;
+</pre>
+
+*** <a name="method">&lt;method&gt;</a>
+
+This tag is the overall containing tag for documenting a method.
+
+**** Syntax
+
+<code>&lt;method name="methodname"&gt;documentation&lt;/method&gt;</code>
+
+**** Example
+
+<pre>
+&lt;method name="op_Equality(Graphics.Point,Graphics.Point)"&gt;
+    &lt;summary&gt;
+        This operator determines whether two points have
+        the same location.
+    &lt;/summary&gt;
+    &lt;param name="p1"&gt;
+        &lt;c&gt;p1&lt;/c&gt; is the first Point to be compared.

+    &lt;seealso cref="op_Inequality(Graphics.Point,Graphics.Point)" /&gt;
+&lt;/method&gt;
+</pre>
+
+*** <a name="para">&lt;para&gt;</a>
+
+
+This tag is for use inside other tags such as <code>&lt;remarks&gt;</code> or <code>&lt;returns&gt;</code>, and 
+allows text to be structured into paragraphs.
+
+**** Syntax
+
+<code>&lt;para&gt;text&lt;/para&gt;</code>
+
+**** Example
+
+<pre>
+&lt;summary&gt;
+    &lt;para&gt;
+    This is the entry point of the &lt;c&gt;Point&lt;/c&gt; class testing 
+    program.
+    &lt;/para&gt;
+    &lt;para&gt;
+    This program tests each method and operator, and
+    is intended to be run after any non-trivial maintenance has
+    been performed on the &lt;c&gt;Point&lt;/c&gt; class.
+    &lt;/para&gt;
+&lt;/summary&gt;
+</pre>
+
+*** <a name="param">&lt;param&gt;</a>
+
+This tag is used to describe a parameter for a method, constructor, or 
+indexer.
+
+**** Syntax
+
+<code>&lt;param name="name"&gt;description&lt;/param&gt;</code>
+	
+<blockquote>
+<em>name</em><br />
+The name of the parameter.

+<code>&lt;paramref name="name" /&gt;</code>
+
+<blockquote>
+<em>name</em><br />
+The name of the parameter.
+</blockquote>
+
+**** Example
+
+<pre>
+&lt;summary&gt;
+    This constructor initializes the new Point to
+    (&lt;paramref name="xor" /&gt;,&lt;paramref name="yor" /&gt;).
+&lt;/summary&gt;
+&lt;param name="xor"&gt;&lt;c&gt;xor&lt;/c&gt; is the new x-coordinate.&lt;/param&gt;

+The name of a member.</br>
+</blockquote>
+
+**** Example
+
+<pre>
+&lt;permission cref="System.Security.PermissionSet"&gt;
+    Everyone can access this method.
+&lt;/permission&gt;
+</pre>        
+
+*** <a name="property">&ltproperty&gt;</a>
+
+This tag is the overall containing tag for documenting a property.
+
+**** Syntax
+
+<code>&lt;property name="propertyname"&gt;documentation&lt;/property&gt;</code>
+
+<blockquote>

+<pre>
+&lt;property name="X"&gt;
+    &lt;summary&gt;
+        Gets or sets the point's x-coordinate.
+    &lt;value&gt;
+        The point's x-coordinate.
+    &lt;/value&gt;
+&lt;/property&gt;
+</pre>
+
+
+*** <a name="remarks">&lt;remarks&gt;</a>
+
+This tag contains extended discussion and information about a member or
+a type. <em>[jbarn: This differs from both the ECMA docs and 
+portions of Microsoft's documentation, but seems consistent with both 
+common usage, and, more importantly, NDoc convention.]</em>
+
+**** Syntax
+
+<code>&lt;remarks&gt;description&lt;/remarks&gt;</code>
+	
+**** Example
+
+<pre>
+&lt;type name="Graphics.Point"&gt;
+    &lt;summary&gt;
+        Models a point in a two-dimensional plane.
+    &lt;/summary&gt;
+    &lt;remarks&gt;
+        Herein I might have an extended discussion of
+        the validity of Cartesian coordinate systems,
+        with examples pro and con, and perhaps
+        some code.
+    &lt;/remarks&gt;
+    
+    &lt;!-- ... --&gt;
+&lt;/type&gt;
+</pre>
+
+*** <a name="returns">&lt;returns&gt;</a>
+
+This tag is used to describe the return value of a method.
+
+**** Syntax
+
+<code>&lt;returns&gt;description&lt;/returns&gt;</code>
+
+**** Example
+
+<pre>
+&lt;method name="op_Inequality(Graphics.Point,Graphics.Point)"&gt;
+    &lt;summary&gt;
+        This operator determines whether two points have the

+    &lt;param name="p2"&gt;&lt;c&gt;p2&lt;/c&gt; is the second Point to be compared.&lt;/param&gt;
+    &lt;returns&gt;
+        True if the points do not have the same location and they
+        have the exact same type; otherwise, false.
+    &lt;/returns&gt;
+&lt;/method&gt;
+</pre>
+
+*** <a name="see">&lt;see&gt;</a>
+
+This tag allows a link to be specified within documentation text.  (Use 
+<code>&lt;seealso&gt;</code> to indicate links that should appear in a 'See Also' section.)
+
+**** Syntax
+
+<code>&lt;see cref="destination" /&gt;</code>
+
+<blockquote>
+<em>cref="destination"</em><br />
+A destination, such as a type or a member of a type.
+</blockquote>
+
+**** Example
+
+<pre>
+&lt;summary&gt;
+    This method changes the point's location to the given
+    coordinates.  This is an asinine way to insert a link,
+    but &lt;see cref="Equals(Object)" /&gt; to understand
+    how points are compared.
+&lt;/summary&gt;
+</pre>	
+
+*** <a name="seealso">&lt;seealso&gt;</a>
+
+This tag allows an entry to be generated for the 'See Also' section.  (Use

+
+**** Syntax
+
+<code>&lt;seealso cref="destination" /&gt;</code>
+	
+<blockquote>
+<em>cref="destination"</em><br />
+A destination, such as a type or a member of a type.

+&lt;seealso cref="op_Inequality(Graphics.Point,Graphics.Point" /&gt;
+</pre>
+
+*** <a name="summary">&lt;summary&gt;</a>
+
+This tag contains a short summary of a member or type, 
+often one sentence. <em>[jbarn: This differs from both the ECMA docs and 
+portions of Microsoft's documentation, but seems consistent with both 
+common usage, and, more importantly, NDoc convention.]</em>
+
+**** Syntax
+
+<code>&lt;summary&gt;description&lt;/summary&gt;</code>
+
+**** Example
+
+<pre>
+&lt;summary&gt;
+    This is the entry point of the &lt;c&gt;Point&lt;/c&gt; class testing
+    program.
+&lt;/summary&gt;
+&lt;remarks&gt;
+    This program tests each method an operator, and is intended
+    to be run after any non-trivial maintenance is performed

+&lt;/remarks&gt;
+</pre>
+
+*** <a name="type">&lt;type&gt;</a>
+
+This tag is the overall containing tag for documenting a type.
+
+**** Syntax
+
+<code>&lttype name="typename" assembly="assemblyname"&gt;documentation&lt;/type&gt;</code>
+
+<blockquote>
+<em>name="typename"</em><br />

+* Updates
+
+	<b>Sep 20, 2001:</b> Microsoft has just announced some changes
+	to passport that are rather interesting.  This document
+	reflects the Passport system without taking into account the
+	new changes.
+
+	Read about it <a href="http://www.microsoft.com/presspass/features/2001/sep01/09-20passport.asp">here</a>.
+
+	For an analysis of security problems with passport, check <a
+	href="http://avirubin.com/passport.html">http://avirubin.com/passport.html</a>.
+	The bottom line is that you should not put any sensitive
+	information on passport.
+
+	I have received many comments from people, and I have updated
+	the page accordingly.  From removing incorrect statements, to
+	fixing typos, to include mentions to other software pieces.
+
+	I also corrected my statement about IIS and a trojan horse, I
+	should read a more educated press in the future.  My apologies
+	to Microsoft and its employees on this particular topic.  IIS
+	did not have a trojan horse built in.
+
+* Microsoft Hailstorm and Passport
+
+	Microsoft Passport is a centralized database hosted by
+	Microsoft that enhances the consumer experience with the Web
+	by providing a single logon system that they can use across a
+	number of participant web sites.
+
+	As you might know by now from our extensive <a
+	href="faq.html">FAQ</a>, the Mono project has nothing to do
+	with Microsoft Hailstorm or <a
+	href="http://www.passport.com">Microsoft Passport.</a>
+
+	Still a lot of people have asked us our opinion on them.
+
+** Passport
+
+	Passport is important not because of it being a breakthrough
+	technologically speaking, but because the company is in a
+	position to drive most people toward being suscribers of it.
+
+	At the time of this writing passport is required to use the
+	free mail service <a href="http://www.hotmail.com">Hotmail</a>
+	to get customized support for the <a
+	href="http://www.msn.com">MSN portal</a>, <a
+	href="http://msdn.microsoft.com">Microsoft Developers
+	Network</a> and according to the original announcement from
+	Microsoft <a href="http://www.americanexpress.com">American
+	Express</a> and <a href="http://www.ebay.com">EBay</a> will be
+	adopting it. 
+
+	There is already a <a
+	href="http://www.passport.com/Directory/Default.asp?PPDir=C&lc=1033">Large
+	list</a> of participating sites.
+
+	There are many current users of it and Microsoft will be
+	driving more users towards Passport as it <a
+	href="http://news.cnet.com/news/0-1003-200-6343275.html">integrates
+	it</a> in their upcoming release of Windows.  
+
+	Microsoft has also <a
+	href="http://www.passport.com/Business/JoinPassportNetwork.asp?lc=1033">developed
+	a toolkit</a> to enable current web merchants to integrate
+	their services with passport.
+
+	To the end user, there is a clear benefit: they only have to
+	log into a single network and not remember multiple passwords
+	across sites on the internet.  Companies that adopt passport
+	will have a competition advantage over those that dont.
+	Microsoft lists a list of <a
+	href="http://www.passport.com/Business/Default.asp?lc=1033">benefits</a>
+	to companies. 
+
+
+** The problems of Passport
+
+	There are a number of concerns that different groups have over
+	Passport.  Sometimes I have some, sometimes I do not.  But
+ 	overall, consumers and businesses can have better solutions.
+
+	<ul>
+		* <b>Single Point of Failure:</b> As more services and
+	 	components depend on remote servers, functionality can
+	 	grind to a halt if there is a failure on the
+	 	centralized Passport system.  
+
+		Such a failure was predicted, and we recently <a
+		href="http://news.cnet.com/news/0-1005-200-6473003.html">witnessed</a> 
+		got a lot of people worried.  
+
+		The outgage lasted for seven days.  Think what this
+	 	could do to your business.
+
+		* <b>Trust:</b> Not everyone trusts Microsoft to keep
+	 	their information confidential.  Concerns are not only
+	 	at the corporate level policy, but also the fact that
+	 	the source code for Microsoft products is not
+	 	available, means that trojans or worms could be built
+	 	into the products by malicious engineers.  
+
+		* <b>Security:</b> With a centralized system like
+	 	Passport, imagine the repercussions of a malicious
+	 	hacker gaining access to the Passport database.
+	 	Personal information and credit card information about
+	 	almost everyone using a computer could be stored there.
+
+		Hackers have already <a
+	 	href="http://slashdot.org/articles/00/10/27/1147248.shtml">broken
+	 	into Microsoft</a> in the past.  And the company was
+	 	unable to figure out for how long their systems had
+		been hacked. 
+
+		Security holes have been found in <a
+		href="http://slashdot.org/articles/00/04/14/0619206.shtml">IIS
+		in the past.</a>  If all the world's data is stored on
+		a central location, when a single security hole is
+		detected, it would allow an intruder to install a
+		backdoor within seconds into the corporate network
+		without people ever noticing. 
+
+		Microsoft itself has been recently hit by worms,
+		imagine if all your business depended on a single
+		provider for providing all or your authentication
+		needs
+	</ul>
+
+	Microsoft might or might not realize this.  The idea behind
+	Passport is indeed a good one (I can start to get rid of my
+	file that keeps track of the 30 logins and passwords or so
+	that I use across the various services on the net myself).
+
+** Alternatives to Microsoft Passport
+
+	An alternative to Microsoft Passport needs to take the above
+	problems into consideration.  Any solution of the form `We
+	will just have a competing offering' will not work.
+
+	The system thus has to be:
+
+	<ul>
+		* <b>Distributed:</b>  The entire authentication
+		system should not create an internet `blackout' in the
+		case of failure.
+
+	 	A distributed system using different software
+		platforms and different vendors would be more
+		resistent to an attack, as holes in a particular
+		implementation of the server software would not affect
+		every person at the same time.  
+
+		A security hole attack might not even be relevant to
+		other software vendors software.
+
+		* <b>Allow for multiple registrars:</b> Users should
+		be able to choose a registrar (their banks, local
+		phone company, service provider, Swiss bank, or any
+		other entity they trust.
+
+		* <b>Mandate good security measures:</b> As a
+		principle, only Open Source software should be used
+		for servers in the registrar, and they should conform
+		to a standard set of tools and software that can be
+		examined by third parties.
+	</ul>
+
+	An implementation of this protocol could use the DNS or a
+	DNS-like setup to distribute the information of users with the
+	possibility of replicating and caching public information
+	about the user.  
+
+	For instant messaging (another piece of the Hailstorm bit),
+	you want to use a non-centralized system like Sun's <a
+	href="http://www.jxta.org">JXTA</a>.  Some people mailed me to
+	mention Jabber as a messaging platform and other people
+	pointed out to the <a
+	href="http://java.sun.com/products/jms/">Java Message
+	Service</a>.   The JMS does support a number of very
+	interesting features that are worth researching.
+
+	It could also just use the user e-mail address as the `key' to
+	choose the registrar (msn.com, hotmail.com -> passport.com;
+	aol.com -> aol.passport.com; you get the idea).
+
+	The <a
+	href="http://www.soapware.org/xmlStorageSystem">xmlStorage</a>
+	idea from <a href="http://www.scripting.com">Dave Winer</a>
+	could be used to store the information.
+
+	A toolkit for various popular web servers could be provided,
+	authenticated and should be open sourced (for those of you who
+	think that a binary program would give more security and would
+	prevent people from tampering: you are wrong.  You can always
+	use a proxy system that "behaves" like the binary, and passes
+	information back and forth from the real program, and snoops
+	in-transit information).
+
+	Good cryptographers need to be involved in this problem to
+	figure out the details and the possible insecure pieces of a
+	proposal like this.
+
+** Implementation: In short
+
+	To keep it short: <b>DNS, JXTA, xmlStorage.</b>
+
+
+** Deploying it
+
+	The implementation of such a system should be a pretty
+	straightforward task once security cryptographers have
+	designed such a beast.  
+
+	The major problems are:
+
+	<ul>
+		* <b>People might just not care:</b> In a poll to US
+		citizens a couple of decades ago, it was found that
+		most people did not care about the rights they were
+		given by the Bill of Rights, which lead to a number of
+		laws to be passed in the US that eliminated most of
+		the rights people had.  
+
+		* <b>The industry will move way too slow:</b>
+		Microsoft's implementation is out in the open now: it
+		is being deployed, and soon it will be insinuated to
+		many, many users.  The industry needs to get together
+		soon if they care about this issue.
+
+		By the time the industry reacts, it might be too
+		late. 
+	</ul>
+
+** Passport and Mono
+
+	The .NET class libraries include a Passport class that
+	applications might use to authenticate with Passport.  Since
+	we do not have information at this point on the exact protocol
+	of Passport, it is not even feasible to implement it.
+
+	If at some point the information is disclosed, it could be
+	implemented.  
+
+	If a competing system to Passport existed, we could probably
+	hide all the authentication information to use a number of
+	different passport-like systems.
+
+	If a user does not want to use Passport at all, he could
+	always turn it off (or completely remove the class from the
+	library).  After all, this is free software.
+
+	Currently, we are too far from the point where this is a real
+	issue. 
+
+** Passport and endangering Open Source.
+
+	A few people have said: `Mono will allow Passport to be
+	available for Linux and that is bad'.  This is plain
+	misinformation.
+
+	Currently, you can obtain Passport for Linux from Microsoft
+	itself and deploy it today on your Web server.  Mono does not
+	even enter the picture here.  Go to passport.com and download
+	the toolkit and you will see with your own eyes that passport
+	is <B>already</b> available for Linux. 
+
+** Disclaimer
+

+* How to port Mono to your preferred architecture
+
+** Endian, 64 bits and unaligned access issues
+
+	The first thing to do is to check that the metadata handling
+	library works on your target processor. You may use the disassembler
+	on simple programs and check that you get sensible results
+	(assuming it compiles at all on your system:-).
+
+	The main issue is to write macros that read unaligned
+	little endian shorts/ints/longs/float/doubles: look into
+	mono/metadata/endian.h. There may be other spots in the code that are
+	unsafe at reading/writing to some datatypes that require special
+	alignment, but there should be few such issues and they need to be fixed.
+
+	Once this stuff is sorted out, you should be able to run the interpreter
+	on simple programs that don't require delegates, P/Invoke functions etc..
+
+** Generating assembly bytecodes for the target processor
+
+	Next, you need to provide the support code for generating assembly bytecode
+	for your target platform (in mono/arch/{ppc,sparc,alpha,*}).
+	The code should be more or less like the code in x86-codegen.h:
+	macros that produce fast in-line code. You don't need to provide
+	code to create every possible code, at first, just the code to
+	create trampolines and execute them is fine (you'll need to research
+	how the call convention works on your platform): that would be, for
+	example, the prolog and epilog code in a function, code to pass function
+	parameters and deal with the return value and so on.
+
+	libffi in gcc or the xptcall sources in mozilla may be helpful to
+	understand how the calling convention works, if you can't find a specification.
+	You'd need a processor manual to know how to create the assembly binary data.
+	This requires a lot of reading if you're not familiar with the assembly for your
+	target platform. Manuals for many processors are available as PDF files on the
+	web site of the respective vendors. Note that some processors require you to
+	flush the I-cache before executing the code: have a look at how the same thing is
+	done in GNU lightning.
+
+** Getting the interpreter to work
+
+	Once you can generate binary code, you can start working on a
+	mono_create_trampoline() function for your platform: this function will receive
+	a MonoMethod that describes the arguments and the return type of a C function
+	and will create the code to call such function. When this function is complete
+	you'll be able to run more sample programs, that use System.IO, P/Invoke
+	functions etc.
+
+	To support delegates you'll need to write a mono_create_method_pointer()
+	function that creates a native function: this can be used to call the
+	method using the runtime's calling convention (it's basically the reverse
+	of mono_create_trampoline()).
+
+** The final step: porting the JIT
+
+	At this point you'd need to have a more complete code generation header file
+	and you can start writing the machine description file for the monoburg
+	system. This code (jit/tesjit.c) will require some machine specific tweaks,
+	but hopefully all you have to do is create the grammar that emit assembly
+	code from the IR tree. Work is at the early stages also for x86 on this stuff
+	as we are still testing various solutions: you'd want to read about burg-like
+	code-generator generators (the LCC book is a good starting point).

+
+* The Mono Project
+
+** Background.
+
+	The GNOME project goal was to bring missing technologies to
+	Unix and make it competitive in the current market place for
+	desktop applications.  We also realized early on that language
+	independence was important, and that is why GNOME APIs were
+	coded using a standard that allowed the APIs to be easily
+	wrapped for other languages.  Our APIs are available to most
+	programming languages on Unix (Perl, Python, Scheme, C++,
+	Objective-C, Ada). 
+
+	Later on we decided to use better methods for encapsulating
+	our APIs, and we started to use CORBA to define interfaces to
+	components. We complemented it with policy and a set of
+	standard GNOME interfaces for easily creating reusable,
+	language independent components, controls and compound
+	documents.  This technology is known as <a
+	href="http://developer.ximian.com/tech/bonobo.html">Bonobo</a>.
+	Interfaces to Bonobo exist for C, Perl, Python, and
+	Java.
+
+	CORBA is good when you define coarse interfaces, and most
+	Bonobo interfaces are coarse.  The only problem is that
+	Bonobo/CORBA interfaces are not good for small interfaces.
+	For example, an XML parsing Bonobo/CORBA component would be
+	inefficient compared to a C API.
+
+** Another explanation
+
+	I recently explained our motivations to Dave Winer, and he posted
+	it <a
+	href="http://scriptingnews.userland.com/stories/storyReader$1275">here</a>
+
+** Microsoft's .NET
+
+	The Microsoft .NET initiative is confusing because it is a
+	company wide effort that ranges from development tools to end
+	user applications.  .NET is a branding formative that
+	has been applied to:
+
+	<ul>
+		* The .NET development platform, a new platform for
+		  writing software.
+
+		* Web services.
+
+		* Microsoft Server Applications.
+
+		* New tools that use the new development platform.
+
+		* Hailstorm, the Passport centralized single-signon
+		  system that is being integrated into Windows XP.
+
+	</ul>
+
+	Mono is an implementation of the .NET development platform.
+
+** The Common Language Infrastructure platform. 
+
+	Microsoft has created a new development platform.  The
+	highlights of this new development platform are:
+
+	<ul>
+		* A runtime environment that provides garbage
+		  collection, threading and a virtual machine
+		  specification (The Virtual Execution System, VES)
+
+		* A comprehensive class library.  
+
+		* A new language, C#.  Very similar to Java,  C#
+		  allows programmers to use all the features available
+		  on the .NET runtime.
+
+		* A language specification that compilers can
+		  follow if they want to generate classes and code
+		  that can interoperate with other programming
+		  languages (The Common Language Specification: CLS)
+	</ul>
+
+	The Common Language Infrastructure platform is similar to the
+  	goals we had in GNOME of giving language independence to
+  	programmers.  It is more mature, documented, larger in scope,
+  	and has a consistent design.
+
+	Any API that is written using a CLS provider language can be
+  	used by any language that is a CLS consumer.  Compilers
+  	generate code in a format called Common Intermediate Language
+  	(CIL) which is an intermediate representation of a compiled
+  	program and is easy to compile to native code or compiled
+  	using Just-in-Time (JIT) engines.  The restrictions placed by
+  	the runtime on the CIL byte codes ensures that it is possible
+  	to do a good job at optimizing the code in a JIT compiler.
+
+	There is not really a lot of innovation in this platform: we
+	have seen all of these concepts before, and we are all
+	familiar with how these things work.
+
+	What makes the Common Language Infrastructure development
+  	platform interesting is that it is a good mix of technologies
+  	that have been nicely integrated.
+
+	The .NET development platform is essentially a new foundation
+	for program development that gives Microsoft a room to grow
+  	for the coming years. 
+
+** ECMA standards.
+
+	Microsoft has submitted the
+  	specifications of C#, the runtime, the metadata and the
+  	other various bits of the .NET development platform to the
+  	<a href="http://www.ecma.ch">ECMA</a> for standarization.
+
+	You can get a copy of the specifications submitted to ECMA
+	from: <a href="http://www.dotnetexperts.com/ecma">http://www.dotnetexperts.com/ecma</a>
+
+** Mono: an Open Source Common Language Infrastructure implementation. 
+
+	Ximian has begun work on Mono, a project that aims to bring
+  	the Common Language Infrastructure platform to free systems.  
+
+	When the GNU project was launched, they picked the best
+  	operating system that was available out there, and they
+  	began to clone it: Unix.
+
+	The .NET development platform is a very rich, powerful, and
+  	well designed platform that would help improve the free
+  	software development platform.  Just like the GNU project
+  	began to clone Unix sixteen years ago, we will be cloning the
+  	.NET development platform because it is a great platform to
+  	build on.
+
+** What makes up Mono?
+
+	There are various pieces that will make up Mono:
+
+	<ul>
+		* A C# compiler.
+
+		* The Virtual Execution System: that will have the
+  		  Just-in-Time compiler, garbage collector, loader,
+  		  threading engine.
+
+		  A byte code interpreter will be provided for quickly
+  		  porting Mono to new systems and debugging the JIT
+		  purposes, but it is not intended to be the ideal
+		  execution environment.
+
+		* An implemenation of the .NET class library.
+
+		* Visual development tools. 
+
+		* A CIL GCC frontend.
+	</ul>
+
+** Why use GNOME components?
+
+	GNOME is an umbrella project that consists of infrastructural
+	components (GUI toolkit, XML libraries, CORBA implementation,
+	printing architecture, imaging system), a desktop environment,
+	and productivity applications.
+
+	The GNOME infrastructural components can be used to quickly
+	implement various pieces of the class libraries without reinventing
+	the wheel, and since all those components are licensed under
+	the terms of the GNU LGPL it is a perfect fit.  
+
+	Libart will be used to implement the Drawing.2D API; Gtk+ and
+	the GNOME libraries will be used to implement the WinForms
+	API and of course Glib and libxml will be used in various
+	places.

+--text follows this line--
+
+Hey!
+
+   July 12 snapshots of class libraries, the compiler and the mono
+runtime are available.
+
+New on this release:
+
+    * Runtime (module: mono)
+
+	The beginning of a simple interpreter that Paolo started
+	workign on (can run really simple .NET programs).
+
+	Disassembler copes with more elements of the binary format and
+	more tokens are decoded.  Paolo is working now on moving some
+	of these to the metadata library. 
+
+	More tables are dumped.
+
+    * Class libraries (module: mcs/class)
+
+	Many new more classes are in from Joe, Vladimir, Jeff, Sean
+	and yours truly.
+
+	Sean fixed the build process, and it is now possible to
+	compile with a single command the assemblies.  We will be
+	revisiting this mechanism in the future to compile per-OS
+	assemblies (ie, Unix, Windows, MacOS, etc).
+
+     * Compiler (module mcs/mcs)
+
+	Not much done this week, just a few fixes here and there, and
+	more work to make it easy to compiler.
+
+     * Documentation (module: mono/doc)
+
+	All the changes to the web site are there for your browsing
+	pleasure.  We still need to integrate the status system in
+	there.

+
+Hey guys,
+
+   I promise I will not be doing these so often once we have the CVS
+server up.  In the meantime:
+
+	* MCS
+
+		Sean got the classes to compile in a single go.  You
+		will need CygWin (www.cygwin.org) to compile though
+		(GNU make and stuff is required).
+
+		System.Xml.XmlReader contribution from Jason
+		(WOOHHOO!!).  It also contains a nice test-suite for
+		his functions, and in his new code bit, his
+		implementation is faster than Microsoft's
+
+		We now ship `jay' as part of the distribution to allow
+		you to compile the compiler with the same `make'
+		command.  Small fixes to the parser as well were
+		introduced. 
+
+	* Mono 0.4
+
+		Paolo's interpreter supports call instructions and has
+		the test suite program that he posted about.
+
+
+		All documentation ships now in the mono-0.4.tar.gz 
+
+Notes:
+
+	As usual, MCS is targeted to be compiled on a Windows machine
+	(you will need Cygwin).
+
+	Mono is targeted to be compiled on a Unix machine or a Windows
+	machine running Cygwin.

+* The Mono runtime
+
+	The Mono runtime implements a JIT engine for the CIL virtual
+	machine (as well as a byte code interpreter, this is to
+	quickly port it to new systems), the class loader, the garbage
+	collector, threading system and metadata access libraries.
+
+	We currently have two runtimes:
+
+	<ul>
+		* <b>mono:</b> The Just In Time compiler implemented
+	 	  using a BURS instruction selector.  We only support
+		  x86 machines in the JIT engine at this point.
+	
+		* <b>mint:</b> The Mono interpreter.  This is an
+		  easy-to-port runtime engine.
+	</ul>
+
+	Currently we are using the Bohem conservative garbage
+	collector, but we working on incorporating the ORP GC engine. 
+
+** Executing MSIL/CIL images
+
+	The code will load an executable and map the references to
+	external assemblies to our own version of the assemblies on
+	Linux.
+
+	Our roadmap looks like this, this has been updated as of
+	<b>Dec 18, 2001</b>:
+
+	<ul>
+
+		* Milestone 1: <b>Done</b> Fully read and parse all CIL byte-codes
+		  and metadata tokens (ie, a disassembler).  
+
+		* Milestone 2: <b>Done</b> Complete an interpreter for CIL byte
+		  codes.  This interpreter can be used temporarly to
+		  run CIL byte code on a system where no JIT is
+		  available.
+
+		* Milestone 3: <b>Done</b>Define an <i>lburg</i>-like
+		  instruction selector for the JITer for Intel.
+
+		* Milestone 4: <b>Done</b> Implement JITer.  This is where our
+		  current efforts are focused on, the JITer currently runs
+		  all of the code we have tested on it.  The major limitation
+		  is that our class libraries are not complete, and hence not
+		  every application can be ran.
+
+		* Milestone 5: Port of the JITer to non IA32 systems.
+	</ul>
+
+	A setup similar to the Kaffe JIT engine will be used to
+	layout the code to support non-IA32 architectures.  Our work
+	will be focused on getting a IA32 version running first.  
+
+	The JIT engine works on Linux and Win32, although you
+	will need to install the CygWin32 development tools to get a
+	Unix-like compilation environment (mostly we use GNU make in 
+	a few of the makefiles).
+
+** JIT Engine (<b>updated, July 8th, 2002</b>)
+
+	The JIT engine uses a code-generator generator approach for
+	compilation.  Given the properties of CIL byte codes, we can
+	take full advantage of a real instruction selector for our
+	code generator. 
+
+	The JIT engine implements a number of optimizations:
+
+	<ul>
+		* Opcode cost estimates (our architecture allows
+	 	  us to generate different code paths depending
+		  on the target CPU dynamically).
+		  
+		* Inlining.
+
+		* Constant folding.  
+
+		  Although compilers typically do
+		  constant folding, the combination of inlining with
+		  constant folding gives some very good results.
+
+		* Linear scan register allocation.  In the past,
+		  register allocation was our achilles heel, but now 
+		  we have left this problem behind.
+	</ul>
+
+	There are a couple of books that deal with this technique: "A
+	Retargetable C Compiler" and "Advanced Compiler Design and
+	Implementation" are good references.  You can also get a
+        technical description of <a
+        href="http://research.microsoft.com/copyright/accept.asp?path=http://www.research.microsoft.com/~drh/pubs/iburg.pdf&pub=ACM">lbrug</a>.
+
+	A few papers that describe the instruction selector:
+
+	<ul>
+		* <a href="http://research.microsoft.com/copyright/accept.asp?path=http://www.research.microsoft.com/~drh/pubs/interface.pdf&pub=wiley">A code generation interface for ANSI C</a>
+
+
+		* <a href="http://research.microsoft.com/copyright/accept.asp?path=http://www.research.microsoft.com/~drh/pubs/iburg.pdf&pub=ACM">Engineering efficient code generators using tree matching and dynamic programming.</a>
+
+	</ul>
+
+** Future plans
+
+	We are evaluating the future directions for the JIT engine:
+	both from our needs (optimizations like inlining, better register allocation,
+	instruction scheduling, and porting to other CPUs).
+
+	We have not yet decided how we will evolve the JIT engine.  We
+	might just upgrade our current architecture, and provide optimizations as
+	an extra layer.
+
+** Garbage Collection
+
+	Currently we are using the Boehm conservative GC.  Although our plans 
+	are to move to the Intel ORP GC engine, our plans on a next generation
+	dual-JIT engine have to be taken into account.
+
+	We will be using the Intel ORP GC engine as it provides a precise
+	garbage collector engine, similar to what is available on the
+	.NET environment. 
+
+	Although using a conservative garbage collector like Bohem's
+	would work, all the type information is available at runtime,
+	so we can actually implement a better collector than a
+	conservative collector.

+	</ul>
+
+** IO and threading
+
+	The ECMA runtime and the .NET runtime assume an IO model and a
+	threading model that is very similar to the Win32 API.  
+
+	Dick Porter has been working on the Mono abstraction layer
+	that allows our runtime to execute code that depend on this
+	behaviour.

+	</ul>
+
+** PInvoke
+
+	PInvoke is the mechanism we are using to wrap Unix API calls
+	as well as talking to system libraries.
+
+	Initially we used libffi, but it was fairly slow, so we have
+	reused parts of the JIT work to create efficient PInvoke trampolines. 
+
+** Remoting
+
+	Mono has support for remoting and proxy objects, just like
+	.NET does.  The runtime provides these facilities.
+
+** Porting
+
+	If you are interested in porting the Mono runtime to other
+	platforms, you might find the pre-compiled <a
+	href="archive/mono-tests.tar.gz">Mono regression test
+	suite</a> useful to debug your implementation.
+
+* COM and XPCOM
+
+	We plan on adding support for XPCOM on Unix and COM on Microsoft
+	Windows later in our development process.

+* Testing
+
+	Testing is an important part of the Mono project: every one of its
+	three major components has a test suite tailored for its needs.  This
+	is very helpful, because in the course of developing the software it
+	is very common to introduce bugs in existing code.  A test suite
+	helps us fix the bugs as soon as they are introduced.
+
+** Class Library Tests
+
+	All classes in Mono libraries should have comprehensive unit test
+	suites to go with them. Unit testing is a software engineering
+  	methodology that makes it easier to build correct code. Every
+  	method in every class should have a set of tests to verify
+  	that they work correctly. Mono also needs a testing framework
+	to make it easy to write and run lots of tests. 
+
+	Try <a href="http://nunit.sourceforge.net">NUnit</a>
+
+	Why do unit testing? It becomes simple to run automated tests
+	for the whole library. Unit tests are a safety net - you can
+	change part of the code and verify that you haven't broken
+	anything. Ideally, tests are written before the actual library
+	code itself. And every time a bug is discovered, a test should
+	be written to demonstrate the bug and its fix. Then, if
+	you ever reintroduce the bug, you will know immediately. For
+	more info, read <a
+	href="http://junit.sourceforge.net/doc/testinfected/testing.htm">
+	JUnit Test Infected: Programmers Love Writing Tests</a>.
+
+
+** Getting Started
+
+	We welcome all contributions to the Class Libary Test Suite.
+
+	There is information to help you get started in CVS at
+	mcs/class/doc/NUnitGuidelines. Once you have written your test, please
+	post it to <a href="mailing-lists.html">mono-list</a>.
+
+	Someone will make sure to add the file or apply the patch as
+	appropriate. If you plan to be an on-going contributor and
+	would like to get cvs account, email <a href="mailto:miguel@ximian.com">miguel</a>.
+
+	Normally, after you send a couple of well-written new files
+	and/or patches to the list, you will be given cvs access.

+* Tools
+
+	We need a number of tools to make people productive using a
+	Mono-based solution.  Some of these tools can be developed on
+	Windows before Mono is fully finished.
+
+	All of these tools should be written using C#.  
+
+	For the tools that are typically command line tools: Try to
+	write these as components that could load their input from
+	streams or collections of streams, and implement the command
+	line tools as wrappers around those classes.
+
+	For example, we will be making the C# compiler a component
+	that could be reused by applications that might have a use for
+	the various bits of the compiler (either to embed the
+	compiler, or reuse the code generator part of it).  
+
+	This is important so that these components (compiler,
+	assembler, linker, etc) can be integrated later into the
+	visual development environment (hopefully with the help of the
+	SharpDevelop hackers). 
+
+TODO=ilasm,IL Assembler
+** IL Assembler.

+	We will need a debugging API to debug CLI applications and
+	then a debugger component that can be used in an IDE
+	environment.
+
+TODO=ide,Integrated Development Environment
+** Integrated Development Environment
+
+	There is already a project to create a C# development
+	environment: <a
+	href="http://www.icsharpcode.net/OpenSource/SD/default.asp">SharpDevelop</a>.
+	People should work with the SharpDevelop hackers to produce a
+	unified development environment.
+
+	Please work with the SharpDevelop hackers to build a good IDE.
+	We will work on creating an embedable compiler component and
+	an embeddable debugger component that can be used withing
+	SharpDevelop
+
+TODO=hbrowser,Help Browser
+** Help Browser
+
+	We need a good help browser that can be used to browse
+	documentation.  Ideally this help browser can accept as input
+	XML Docbook input and an assorted set of file formats
+	(Microsoft Help, Unix manual pages, Unix Info pages)
+
+	Look at the GNOME DevHelp for a good set of ideas on how to
+	implement this.

+* System.Windows.Forms
+
+	System.Windows.Forms eventually will support multiple
+	toolkits.  Ximian will be delivering a product that will allow
+	for System.Windows.Forms applications to integrate with GNOME
+	through Gtk and MacOS X using Cocoa.
+
+	There are no current plans to support embedded devices, but
+	Gtk/FrameBuffer is an option.  If you have suggestions or
+	recommendations, please let us <a
+	href="mailto:mono-hackers-list@ximian.com">let us know</a>
+
+* Contributing
+
+	Currently Ximian developers are busy making our JIT engine
+	feature complete, and dealing with the low-level details of
+	the Mono runtime.
+
+	If you are interested in contributing, you can start stubbing
+	out classes and providing enumerations.  That will help us
+	significantly when we start working on the actual bindings.  
+
+	Christian Meyer is currently organizing this effort.
+
+* System.Drawing
+
+	Using existing libraries to implement some of the functionality required
+
+	<ul>
+		* gdk-pixbuf is a generic image loader that loads an image
+		  and leaves it into an RGB buffer.  It hides all the details
+		  about what image file format is being loaded.
+
+		* Libart is a general framework for rendering RGB/RGBA
+		  buffers into RGB buffers and rendering postscript-like paths into
+		  RGB/RGBA buffers.
+	</ul>
+
+	We want to use gdk-pixbuf as the image loader for the image
+	classes, and then we need operations to render that into the
+	windowing system (Gtk+, MacOS, etc).  But notice how there is
+	very little dependnecies in Gdk-pixbuf on gtk, and libart has
+	none.
+
+	They are pretty independent from a windowing system
+	(gdk-pixbuf comes with some "helper" routines for rendering
+	data into a pixmap and to load pixmaps into RGB buffers).
+
+	A few things to keep in mind:
+	
+	<ul>
+	
+		* gdk-pixbuf can be used to load images for Gtk+,
+		  MacOS X and Windows, it should be pretty portable,
+		  although we might need in the future to back-port
+		  some new features from Gtk head. 
+
+		* Libart is probably only going to be used with X11,
+		  as the MacOS X provides the same features in Quartz,
+		  and Win32 *probably* has that in GDI+.  If not, we
+		  should use libart in Win32 as well (or for older
+		  Windows systems).
+	</ul>
+
+* Directory Layout
+
+        System.Drawing  (assembly directory)
+                System.Drawing.Blah
+                        Common code for "Blah"
+                        Stubs for "Blah" to ease ports.
+
+                Gtk
+                        System.Drawing.Blah.
+                                Gtk ports of "System.Drawing.Blah"
+                MacOS
+                        System.Drawing.Blah
+                                MacOS ports of "System.Drawing.Blah"
+                Win32
+                        System.Drawing.Blah
+                                Win32 ports of "System.Drawing.Blah"
+
+	Then we use nant targets to include/exclude the right set of
+	files to create the assembly.
+
+* Open questions:
+
+	I believe that the graphics contexts that are used to render
+	can accept either libart-like rendering operations and
+	X11-like rendering operations.  This complicates matters, but
+	I am not sure.  Someone needs to investigate this.
