+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  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
+them 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.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If 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 convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero 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
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "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 PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,

+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state 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 program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program 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 Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<http://www.gnu.org/licenses/>.

+# Generic Makefile for building and packaging a Nextcloud app which uses npm and
+# Composer.
+#
+# Dependencies:
+# * make
+# * which
+# * curl: used if phpunit and composer are not installed to fetch them from the web
+# * tar: for building the archive
+# * npm: for building and testing everything JS
+#
+# If no composer.json is in the app root directory, the Composer step
+# will be skipped. The same goes for the package.json which can be located in
+# the app root or the js/ directory.
+#
+# The npm command by launches the npm build script:
+#
+#    npm run build
+#
+# The npm test command launches the npm test script:
+#
+#    npm run test
+#
+# The idea behind this is to be completely testing and build tool agnostic. All
+# build tools and additional package managers should be installed locally in
+# your project, since this won't pollute people's global namespace.
+#
+# The following npm scripts in your package.json install and update the bower
+# and npm dependencies and use gulp as build system (notice how everything is
+# run from the node_modules folder):
+#
+#    "scripts": {
+#        "test": "node node_modules/gulp-cli/bin/gulp.js karma",

+# Instantiator
+
+This library provides a way of avoiding usage of constructors when instantiating PHP classes.

+
+## Installation
+
+The suggested installation method is via [composer](https://getcomposer.org/):
+
+```sh
+php composer.phar require "doctrine/instantiator:~1.0.3"
+```
+
+## Usage
+
+The instantiator is able to create new instances of any class without using the constructor or any API of the class
+itself:
+
+```php
+$instantiator = new \Doctrine\Instantiator\Instantiator();
+
+$instance = $instantiator->instantiate(\My\ClassName\Here::class);
+```
+
+## Contributing
+
+Please read the [CONTRIBUTING.md](CONTRIBUTING.md) contents if you wish to help out!
+
+## Credits
+
+This library was migrated from [ocramius/instantiator](https://github.com/Ocramius/Instantiator), which
+has been donated to the doctrine organization, and which is now deprecated in favour of this package.

+
+## How?
+
+Install with Composer:
+
+```json
+composer require myclabs/deep-copy
+```
+
+Use simply:
+
+```php
+use DeepCopy\DeepCopy;
+
+$copier = new DeepCopy();
+$myCopy = $copier->copy($myObject);
+```
+
+
+## Why?
+
+- How do you create copies of your objects?
+
+```php
+$myCopy = clone $myObject;
+```
+
+- How do you create **deep** copies of your objects (i.e. copying also all the objects referenced in the properties)?
+
+You use [`__clone()`](http://www.php.net/manual/en/language.oop5.cloning.php#object.clone) and implement the behavior
+yourself.
+
+- But how do you handle **cycles** in the association graph?
+
+Now you're in for a big mess :(
+
+![association graph](doc/graph.png)
+

+![Using clone](doc/clone.png)
+

+### Overridding `__clone()`
+
+![Overridding __clone](doc/deep-clone.png)
+
+
+### With `DeepCopy`
+
+![With DeepCopy](doc/deep-copy.png)
+
+
+## How it works
+
+DeepCopy recursively traverses all the object's properties and clones them. To avoid cloning the same object twice it
+keeps a hash map of all instances and thus preserves the object graph.
+
+To use it:
+
+```php
+use function DeepCopy\deep_copy;
+
+$copy = deep_copy($var);
+```
+
+Alternatively, you can create your own `DeepCopy` instance to configure it differently for example:
+
+```php
+use DeepCopy\DeepCopy;
+
+$copier = new DeepCopy(true);
+
+$copy = $copier->copy($var);
+```
+
+You may want to roll your own deep copy function:
+
+```php
+namespace Acme;
+
+use DeepCopy\DeepCopy;
+
+function deep_copy($var)
+{
+    static $copier = null;
+    
+    if (null === $copier) {
+        $copier = new DeepCopy(true);
+    }
+    
+    return $copier->copy($var);
+}
+```
+
+
+## Going further
+
+You can add filters to customize the copy process.
+
+The method to add a filter is `DeepCopy\DeepCopy::addFilter($filter, $matcher)`,
+with `$filter` implementing `DeepCopy\Filter\Filter`
+and `$matcher` implementing `DeepCopy\Matcher\Matcher`.
+
+We provide some generic filters and matchers.
+
+
+### Matchers
+
+  - `DeepCopy\Matcher` applies on a object attribute.
+  - `DeepCopy\TypeMatcher` applies on any element found in graph, including array elements.
+
+
+#### Property name
+
+The `PropertyNameMatcher` will match a property by its name:
+
+```php
+use DeepCopy\Matcher\PropertyNameMatcher;
+
+// Will apply a filter to any property of any objects named "id"
+$matcher = new PropertyNameMatcher('id');
+```
+
+
+#### Specific property
+
+The `PropertyMatcher` will match a specific property of a specific class:
+
+```php
+use DeepCopy\Matcher\PropertyMatcher;
+
+// Will apply a filter to the property "id" of any objects of the class "MyClass"
+$matcher = new PropertyMatcher('MyClass', 'id');
+```
+
+
+#### Type
+
+The `TypeMatcher` will match any element by its type (instance of a class or any value that could be parameter of
+[gettype()](http://php.net/manual/en/function.gettype.php) function):
+
+```php
+use DeepCopy\TypeMatcher\TypeMatcher;
+
+// Will apply a filter to any object that is an instance of Doctrine\Common\Collections\Collection
+$matcher = new TypeMatcher('Doctrine\Common\Collections\Collection');
+```
+
+
+### Filters
+
+- `DeepCopy\Filter` applies a transformation to the object attribute matched by `DeepCopy\Matcher`
+- `DeepCopy\TypeFilter` applies a transformation to any element matched by `DeepCopy\TypeMatcher`
+
+
+#### `SetNullFilter` (filter)
+
+Let's say for example that you are copying a database record (or a Doctrine entity), so you want the copy not to have
+any ID:
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\SetNullFilter;
+use DeepCopy\Matcher\PropertyNameMatcher;
+
+$object = MyClass::load(123);
+echo $object->id; // 123
+
+$copier = new DeepCopy();
+$copier->addFilter(new SetNullFilter(), new PropertyNameMatcher('id'));
+
+$copy = $copier->copy($object);
+
+echo $copy->id; // null
+```
+
+
+#### `KeepFilter` (filter)
+
+If you want a property to remain untouched (for example, an association to an object):
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\KeepFilter;
+use DeepCopy\Matcher\PropertyMatcher;
+
+$copier = new DeepCopy();
+$copier->addFilter(new KeepFilter(), new PropertyMatcher('MyClass', 'category'));
+
+$copy = $copier->copy($object);
+// $copy->category has not been touched
+```
+
+
+#### `DoctrineCollectionFilter` (filter)
+
+If you use Doctrine and want to copy an entity, you will need to use the `DoctrineCollectionFilter`:
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\Doctrine\DoctrineCollectionFilter;
+use DeepCopy\Matcher\PropertyTypeMatcher;
+
+$copier = new DeepCopy();
+$copier->addFilter(new DoctrineCollectionFilter(), new PropertyTypeMatcher('Doctrine\Common\Collections\Collection'));
+
+$copy = $copier->copy($object);
+```
+
+
+#### `DoctrineEmptyCollectionFilter` (filter)
+
+If you use Doctrine and want to copy an entity who contains a `Collection` that you want to be reset, you can use the
+`DoctrineEmptyCollectionFilter`
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\Doctrine\DoctrineEmptyCollectionFilter;
+use DeepCopy\Matcher\PropertyMatcher;
+
+$copier = new DeepCopy();
+$copier->addFilter(new DoctrineEmptyCollectionFilter(), new PropertyMatcher('MyClass', 'myProperty'));
+
+$copy = $copier->copy($object);
+
+// $copy->myProperty will return an empty collection
+```
+
+
+#### `DoctrineProxyFilter` (filter)
+
+If you use Doctrine and use cloning on lazy loaded entities, you might encounter errors mentioning missing fields on a
+Doctrine proxy class (...\\\_\_CG\_\_\Proxy).
+You can use the `DoctrineProxyFilter` to load the actual entity behind the Doctrine proxy class.
+**Make sure, though, to put this as one of your very first filters in the filter chain so that the entity is loaded
+before other filters are applied!**
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\Doctrine\DoctrineProxyFilter;
+use DeepCopy\Matcher\Doctrine\DoctrineProxyMatcher;
+
+$copier = new DeepCopy();
+$copier->addFilter(new DoctrineProxyFilter(), new DoctrineProxyMatcher());
+
+$copy = $copier->copy($object);
+
+// $copy should now contain a clone of all entities, including those that were not yet fully loaded.
+```
+
+
+#### `ReplaceFilter` (type filter)
+
+1. If you want to replace the value of a property:
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\Filter\ReplaceFilter;
+use DeepCopy\Matcher\PropertyMatcher;
+
+$copier = new DeepCopy();
+$callback = function ($currentValue) {
+  return $currentValue . ' (copy)'
+};
+$copier->addFilter(new ReplaceFilter($callback), new PropertyMatcher('MyClass', 'title'));
+
+$copy = $copier->copy($object);
+
+// $copy->title will contain the data returned by the callback, e.g. 'The title (copy)'
+```
+
+2. If you want to replace whole element:
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\TypeFilter\ReplaceFilter;
+use DeepCopy\TypeMatcher\TypeMatcher;
+
+$copier = new DeepCopy();
+$callback = function (MyClass $myClass) {
+  return get_class($myClass);
+};
+$copier->addTypeFilter(new ReplaceFilter($callback), new TypeMatcher('MyClass'));
+
+$copy = $copier->copy([new MyClass, 'some string', new MyClass]);
+
+// $copy will contain ['MyClass', 'some string', 'MyClass']
+```
+
+
+The `$callback` parameter of the `ReplaceFilter` constructor accepts any PHP callable.
+
+
+#### `ShallowCopyFilter` (type filter)
+
+Stop *DeepCopy* from recursively copying element, using standard `clone` instead:
+
+```php
+use DeepCopy\DeepCopy;
+use DeepCopy\TypeFilter\ShallowCopyFilter;
+use DeepCopy\TypeMatcher\TypeMatcher;
+use Mockery as m;
+
+$this->deepCopy = new DeepCopy();
+$this->deepCopy->addTypeFilter(
+	new ShallowCopyFilter,
+	new TypeMatcher(m\MockInterface::class)
+);
+
+$myServiceWithMocks = new MyService(m::mock(MyDependency1::class), m::mock(MyDependency2::class));
+// All mocks will be just cloned, not deep copied
+```
+
+
+## Edge cases
+
+The following structures cannot be deep-copied with PHP Reflection. As a result they are shallow cloned and filters are
+not applied. There is two ways for you to handle them:
+
+- Implement your own `__clone()` method
+- Use a filter with a type matcher
+

+### Tests

+Running the tests is simple:

+# Changelog
+
+# 3.1.2 (2017-11-17)
+- Changed the algorithm for adding paddings to zipalign. 
+  Now we will use the special field ExtraField c ID 0xD935, 
+  which was implemented by Google in the apksigner library. 
+  Now this field corresponds to the ZIP standard for storing 
+  ExtraField records, and not just filling with zero bytes, 
+  as in the zipalign console utility.
+
+## 3.1.1 (2017-11-15)
+- Fix resave zip aligned archive
+
+## 3.1.0 (2017-11-14)
+- Added class `ZipModel` for all changes.
+- All manipulations with incoming and outgoing streams are in separate files: `ZipInputStream` and `ZipOutputStream`.
+- Removed class `CentralDirectory`.
+- Optimized extra fields classes.
+- Fixed issue #4 (`count()` returns 0 when files are added in directories).
+- Implemented issue #8 - support inline Content-Disposition and empty output filename.
+- Optimized and tested on a php 32-bit platform (issue #5).
+- Added output as PSR-7 Response.
+- Added methods for canceling changes.
+- Added [russian documentation](README.RU.md).
+- Updated [documentation](README.md).
+- Declared deprecated methods:
+  + rename `ZipFile::withReadPassword` to `ZipFile::setReadPassword`
+  + rename `ZipFile::withNewPassword` to `ZipFile::setPassword`
+  + rename `ZipFile::withoutPassword` to `ZipFile::disableEncryption`
+
+## 3.0.3 (2017-11-11)
+Fix bug issue #8 - Error if the file is empty.
+
+## 3.0.0 (2017-03-15)
+Merge `ZipOutputFile` with ZipFile and optimize the zip archive update.
+
+See the update instructions in README.md.
+
+## 2.2.0 (2017-03-02)
+Features:
+  - create output object `ZipOutputFile` from `ZipFile` in method `ZipFile::edit()`.
+  - create output object `ZipOutputFile` from filename in static method `ZipOutputFile::openFromFile(string $filename)`.

+### <a name="Features"></a> Features
+- Opening and unzipping zip files.
+- Creating ZIP-archives.
+- Modifying ZIP archives.
+- Pure php (not require extension `php-zip` and class `\ZipArchive`).
+- It supports saving the archive to a file, outputting the archive to the browser, or outputting it as a string without saving it to a file.
+- Archival comments and comments of individual entry are supported.
+- Get information about each entry in the archive.
+- Only the following compression methods are supported:
+  + No compressed (Stored).
+  + Deflate compression.
+  + BZIP2 compression with the extension `php-bz2`.
+- Support for `ZIP64` (file size is more than 4 GB or the number of entries in the archive is more than 65535).
+- Built-in support for aligning the archive to optimize Android packages (APK) [`zipalign`](https://developer.android.com/studio/command-line/zipalign.html).
+- Working with passwords for PHP 5.5
+  > **Attention!**
+  >
+  > For 32-bit systems, the `Traditional PKWARE Encryption (ZipCrypto)` encryption method is not currently supported. 
+  > Use the encryption method `WinZIP AES Encryption`, whenever possible.
+  + Set the password to read the archive for all entries or only for some.
+  + Change the password for the archive, including for individual entries.
+  + Delete the archive password for all or individual entries.
+  + Set the password and/or the encryption method, both for all, and for individual entries in the archive.
+  + Set different passwords and encryption methods for different entries.
+  + Delete the password for all or some entries.
+  + Support `Traditional PKWARE Encryption (ZipCrypto)` and `WinZIP AES Encryption` encryption methods.
+  + Set the encryption method for all or individual entries in the archive.
+
+### <a name="Requirements"></a> Requirements
+- `PHP` >= 5.5 (preferably 64-bit).
+- Optional php-extension `bzip2` for BZIP2 compression.
+- Optional php-extension `openssl` or `mcrypt` for `WinZip Aes Encryption` support.

+The ReflectionDocBlock Component [![Build Status](https://secure.travis-ci.org/phpDocumentor/ReflectionDocBlock.png)](https://travis-ci.org/phpDocumentor/ReflectionDocBlock)
+================================
+
+Introduction
+------------
+
+The ReflectionDocBlock component of phpDocumentor provides a DocBlock parser
+that is 100% compatible with the [PHPDoc standard](http://phpdoc.org/docs/latest).
+
+With this component, a library can provide support for annotations via DocBlocks
+or otherwise retrieve information that is embedded in a DocBlock.
+
+Installation
+------------
+
+```bash
+composer require phpdocumentor/reflection-docblock
+```
+
+Usage
+-----
+
+In order to parse the DocBlock one needs a DocBlockFactory that can be
+instantiated using its `createInstance` factory method like this:
+
+```php
+$factory  = \phpDocumentor\Reflection\DocBlockFactory::createInstance();
+```
+
+Then we can use the `create` method of the factory to interpret the DocBlock. 
+Please note that it is also possible to provide a class that has the 
+`getDocComment()` method, such as an object of type `ReflectionClass`, the
+create method will read that if it exists.
+
+```php
+$docComment = <<<DOCCOMMENT
+/**
+ * This is an example of a summary.
+ *
+ * This is a Description. A Summary and Description are separated by either
+ * two subsequent newlines (thus a whiteline in between as can be seen in this
+ * example), or when the Summary ends with a dot (`.`) and some form of
+ * whitespace.
+ */
+DOCCOMMENT;
+
+$docblock = $factory->create($docComment);
+```
+
+The `create` method will yield an object of type `\phpDocumentor\Reflection\DocBlock`
+whose methods can be queried:
+
+```php
+// Contains the summary for this DocBlock
+$summary = $docblock->getSummary();
+
+// Contains \phpDocumentor\Reflection\DocBlock\Description object
+$description = $docblock->getDescription();
+
+// You can either cast it to string
+$description = (string) $docblock->getDescription();
+
+// Or use the render method to get a string representation of the Description.
+$description = $docblock->getDescription()->render();
+```
+
+> For more examples it would be best to review the scripts in the [`/examples` folder](/examples).

+/**
+ * Object representing to description for a DocBlock.
+ *
+ * A Description object can consist of plain text but can also include tags. A Description Formatter can then combine
+ * a body template with sprintf-style placeholders together with formatted tags in order to reconstitute a complete
+ * description text using the format that you would prefer.
+ *
+ * Because parsing a Description text can be a verbose process this is handled by the {@see DescriptionFactory}. It is
+ * thus recommended to use that to create a Description object, like this:
+ *
+ *     $description = $descriptionFactory->create('This is a {@see Description}', $context);
+ *
+ * The description factory will interpret the given body and create a body template and list of tags from them, and pass
+ * that onto the constructor if this class.
+ *
+ * > The $context variable is a class of type {@see \phpDocumentor\Reflection\Types\Context} and contains the namespace
+ * > and the namespace aliases that apply to this DocBlock. These are used by the Factory to resolve and expand partial
+ * > type names and FQSENs.
+ *
+ * If you do not want to use the DescriptionFactory you can pass a body template and tag listing like this:
+ *
+ *     $description = new Description(
+ *         'This is a %1$s',
+ *         [ new See(new Fqsen('\phpDocumentor\Reflection\DocBlock\Description')) ]
+ *     );
+ *
+ * It is generally recommended to use the Factory as that will also apply escaping rules, while the Description object
+ * is mainly responsible for rendering.
+ *
+ * @see DescriptionFactory to create a new Description.
+ * @see Description\Formatter for the formatting of the body and tags.

+TypeResolver and FqsenResolver
+==============================
+
+The specification on types in DocBlocks (PSR-5) describes various keywords and special constructs
+but also how to statically resolve the partial name of a Class into a Fully Qualified Class Name (FQCN).
+
+PSR-5 also introduces an additional way to describe deeper elements than Classes, Interfaces and Traits 
+called the Fully Qualified Structural Element Name (FQSEN). Using this it is possible to refer to methods,
+properties and class constants but also functions and global constants.
+
+This package provides two Resolvers that are capable of 
+
+1. Returning a series of Value Object for given expression while resolving any partial class names, and 
+2. Returning an FQSEN object after resolving any partial Structural Element Names into Fully Qualified Structural 
+   Element names.
+
+## Installing
+
+The easiest way to install this library is with [Composer](https://getcomposer.org) using the following command:
+
+    $ composer require phpdocumentor/type-resolver
+
+## Examples
+
+Ready to dive in and don't want to read through all that text below? Just consult the [examples](examples) folder and
+check which type of action that your want to accomplish.
+
+## On Types and Element Names
+
+This component can be used in one of two ways
+ 
+1. To resolve a Type or
+2. To resolve a Fully Qualified Structural Element Name
+ 
+The big difference between these two is in the number of things it can resolve. 
+
+The TypeResolver can resolve:
+
+- a php primitive or pseudo-primitive such as a string or void (`@var string` or `@return void`).
+- a composite such as an array of string (`@var string[]`).
+- a compound such as a string or integer (`@var string|integer`).
+- an object or interface such as the TypeResolver class (`@var TypeResolver` 
+  or `@var \phpDocumentor\Reflection\TypeResolver`)
+
+  > please note that if you want to pass partial class names that additional steps are necessary, see the 
+  > chapter `Resolving partial classes and FQSENs` for more information.
+
+Where the FqsenResolver can resolve:
+
+- Constant expressions (i.e. `@see \MyNamespace\MY_CONSTANT`)
+- Function expressions (i.e. `@see \MyNamespace\myFunction()`)
+- Class expressions (i.e. `@see \MyNamespace\MyClass`)
+- Interface expressions (i.e. `@see \MyNamespace\MyInterface`)
+- Trait expressions (i.e. `@see \MyNamespace\MyTrait`)
+- Class constant expressions (i.e. `@see \MyNamespace\MyClass::MY_CONSTANT`)
+- Property expressions (i.e. `@see \MyNamespace\MyClass::$myProperty`)
+- Method expressions (i.e. `@see \MyNamespace\MyClass::myMethod()`)
+
+## Resolving a type
+
+In order to resolve a type you will have to instantiate the class `\phpDocumentor\Reflection\TypeResolver`
+and call its `resolve` method like this:
+
+```php
+$typeResolver = new \phpDocumentor\Reflection\TypeResolver();
+$type = $typeResolver->resolve('string|integer');
+```
+
+In this example you will receive a Value Object of class `\phpDocumentor\Reflection\Types\Compound` that has two 
+elements, one of type `\phpDocumentor\Reflection\Types\String_` and one of type 
+`\phpDocumentor\Reflection\Types\Integer`.
+
+The real power of this resolver is in its capability to expand partial class names into fully qualified class names; but
+in order to do that we need an additional `\phpDocumentor\Reflection\Types\Context` class that will inform the resolver 
+in which namespace the given expression occurs and which namespace aliases (or imports) apply.
+
+## Resolving an FQSEN
+
+A Fully Qualified Structural Element Name is a reference to another element in your code bases and can be resolved using
+the `\phpDocumentor\Reflection\FqsenResolver` class' `resolve` method, like this:
+
+```php
+$fqsenResolver = new \phpDocumentor\Reflection\FqsenResolver();
+$fqsen = $fqsenResolver->resolve('\phpDocumentor\Reflection\FqsenResolver::resolve()');
+```
+
+In this example we resolve a Fully Qualified Structural Element Name (meaning that it includes the full namespace, class
+name and element name) and receive a Value Object of type `\phpDocumentor\Reflection\Fqsen`.
+
+The real power of this resolver is in its capability to expand partial element names into Fully Qualified Structural 
+Element Names; but in order to do that we need an additional `\phpDocumentor\Reflection\Types\Context` class that will 
+inform the resolver in which namespace the given expression occurs and which namespace aliases (or imports) apply.
+
+## Resolving partial Classes and Structural Element Names
+
+Perhaps the best feature of this library is that it knows how to resolve partial class names into fully qualified class 
+names.
+
+For example, you have this file:
+
+```php
+namespace My\Example;
+
+use phpDocumentor\Reflection\Types;
+
+class Classy
+{
+    /**
+     * @var Types\Context

+    
+    public function otherFunction(){}
+}
+```
+
+Suppose that you would want to resolve (and expand) the type in the `@var` tag and the element name in the `@see` tag.
+For the resolvers to know how to expand partial names you have to provide a bit of _Context_ for them by instantiating
+a new class named `\phpDocumentor\Reflection\Types\Context` with the name of the namespace and the aliases that are in 
+play.
+
+### Creating a Context
+
+You can do this by manually creating a Context like this:
+
+```php
+$context = new \phpDocumentor\Reflection\Types\Context(
+    '\My\Example', 
+    [ 'Types' => '\phpDocumentor\Reflection\Types']
+);
+```
+
+Or by using the `\phpDocumentor\Reflection\Types\ContextFactory` to instantiate a new context based on a Reflector 
+object or by providing the namespace that you'd like to extract and the source code of the file in which the given
+type expression occurs.
+
+```php
+$contextFactory = new \phpDocumentor\Reflection\Types\ContextFactory();
+$context = $contextFactory->createFromReflector(new ReflectionMethod('\My\Example\Classy', '__construct'));
+```
+
+or
+
+```php
+$contextFactory = new \phpDocumentor\Reflection\Types\ContextFactory();
+$context = $contextFactory->createForNamespace('\My\Example', file_get_contents('My/Example/Classy.php'));
+```
+
+### Using the Context
+
+After you have obtained a Context it is just a matter of passing it along with the `resolve` method of either Resolver 
+class as second argument and the Resolvers will take this into account when resolving partial names.
+
+To obtain the resolved class name for the `@var` tag in the example above you can do:
+
+```php
+$typeResolver = new \phpDocumentor\Reflection\TypeResolver();
+$type = $typeResolver->resolve('Types\Context', $context);
+```
+
+When you do this you will receive an object of class `\phpDocumentor\Reflection\Types\Object_` for which you can call 
+the `getFqsen` method to receive a Value Object that represents the complete FQSEN. So that would be 
+`phpDocumentor\Reflection\Types\Context`.
+
+> Why is the FQSEN wrapped in another object `Object_`?
+> 
+> The resolve method of the TypeResolver only returns object with the interface `Type` and the FQSEN is a common
+> type that does not represent a Type. Also: in some cases a type can represent an "Untyped Object", meaning that it
+> is an object (signified by the `object` keyword) but does not refer to a specific element using an FQSEN.
+
+Another example is on how to resolve the FQSEN of a method as can be seen with the `@see` tag in the example above. To
+resolve that you can do the following:
+
+```php
+$fqsenResolver = new \phpDocumentor\Reflection\FqsenResolver();
+$type = $fqsenResolver->resolve('Classy::otherFunction()', $context);
+```
+
+Because Classy is a Class in the current namespace its FQSEN will have the `My\Example` namespace and by calling the 
+`resolve` method of the FQSEN Resolver you will receive an `Fqsen` object that refers to 
+`\My\Example\Classy::otherFunction()`.

+# Prophecy
+
+[![Stable release](https://poser.pugx.org/phpspec/prophecy/version.svg)](https://packagist.org/packages/phpspec/prophecy)
+[![Build Status](https://travis-ci.org/phpspec/prophecy.svg?branch=master)](https://travis-ci.org/phpspec/prophecy)
+
+Prophecy is a highly opinionated yet very powerful and flexible PHP object mocking
+framework. Though initially it was created to fulfil phpspec2 needs, it is flexible
+enough to be used inside any testing framework out there with minimal effort.
+
+## A simple example
+
+```php
+<?php
+
+class UserTest extends PHPUnit_Framework_TestCase
+{
+    private $prophet;
+
+    public function testPasswordHashing()
+    {
+        $hasher = $this->prophet->prophesize('App\Security\Hasher');
+        $user   = new App\Entity\User($hasher->reveal());
+
+        $hasher->generateHash($user, 'qwerty')->willReturn('hashed_pass');
+
+        $user->setPassword('qwerty');
+
+        $this->assertEquals('hashed_pass', $user->getPassword());
+    }
+
+    protected function setup()
+    {
+        $this->prophet = new \Prophecy\Prophet;
+    }
+
+    protected function tearDown()
+    {
+        $this->prophet->checkPredictions();
+    }
+}
+```
+
+## Installation
+
+### Prerequisites
+
+Prophecy requires PHP 5.3.3 or greater.
+
+### Setup through composer
+
+First, add Prophecy to the list of dependencies inside your `composer.json`:
+
+```json
+{
+    "require-dev": {
+        "phpspec/prophecy": "~1.0"
+    }
+}
+```
+
+Then simply install it with composer:
+
+```bash
+$> composer install --prefer-dist
+```
+
+You can read more about Composer on its [official webpage](http://getcomposer.org).
+
+## How to use it
+
+First of all, in Prophecy every word has a logical meaning, even the name of the library
+itself (Prophecy). When you start feeling that, you'll become very fluid with this
+tool.
+
+For example, Prophecy has been named that way because it concentrates on describing the future
+behavior of objects with very limited knowledge about them. But as with any other prophecy,
+those object prophecies can't create themselves - there should be a Prophet:
+
+```php
+$prophet = new Prophecy\Prophet;
+```
+
+The Prophet creates prophecies by *prophesizing* them:
+
+```php
+$prophecy = $prophet->prophesize();
+```
+
+The result of the `prophesize()` method call is a new object of class `ObjectProphecy`. Yes,
+that's your specific object prophecy, which describes how your object would behave
+in the near future. But first, you need to specify which object you're talking about,
+right?
+
+```php
+$prophecy->willExtend('stdClass');
+$prophecy->willImplement('SessionHandlerInterface');
+```
+
+There are 2 interesting calls - `willExtend` and `willImplement`. The first one tells
+object prophecy that our object should extend specific class, the second one says that
+it should implement some interface. Obviously, objects in PHP can implement multiple
+interfaces, but extend only one parent class.
+
+### Dummies
+
+Ok, now we have our object prophecy. What can we do with it? First of all, we can get
+our object *dummy* by revealing its prophecy:
+
+```php
+$dummy = $prophecy->reveal();
+```
+
+The `$dummy` variable now holds a special dummy object. Dummy objects are objects that extend
+and/or implement preset classes/interfaces by overriding all their public methods. The key
+point about dummies is that they do not hold any logic - they just do nothing. Any method
+of the dummy will always return `null` and the dummy will never throw any exceptions.
+Dummy is your friend if you don't care about the actual behavior of this double and just need
+a token object to satisfy a method typehint.
+
+You need to understand one thing - a dummy is not a prophecy. Your object prophecy is still
+assigned to `$prophecy` variable and in order to manipulate with your expectations, you
+should work with it. `$dummy` is a dummy - a simple php object that tries to fulfil your
+prophecy.
+
+### Stubs
+
+Ok, now we know how to create basic prophecies and reveal dummies from them. That's
+awesome if we don't care about our _doubles_ (objects that reflect originals)
+interactions. If we do, we need to use *stubs* or *mocks*.
+
+A stub is an object double, which doesn't have any expectations about the object behavior,
+but when put in specific environment, behaves in specific way. Ok, I know, it's cryptic,
+but bear with me for a minute. Simply put, a stub is a dummy, which depending on the called
+method signature does different things (has logic). To create stubs in Prophecy:
+
+```php
+$prophecy->read('123')->willReturn('value');
+```
+
+Oh wow. We've just made an arbitrary call on the object prophecy? Yes, we did. And this
+call returned us a new object instance of class `MethodProphecy`. Yep, that's a specific
+method with arguments prophecy. Method prophecies give you the ability to create method
+promises or predictions. We'll talk about method predictions later in the _Mocks_ section.
+
+#### Promises
+
+Promises are logical blocks, that represent your fictional methods in prophecy terms
+and they are handled by the `MethodProphecy::will(PromiseInterface $promise)` method.
+As a matter of fact, the call that we made earlier (`willReturn('value')`) is a simple
+shortcut to:
+
+```php
+$prophecy->read('123')->will(new Prophecy\Promise\ReturnPromise(array('value')));
+```
+
+This promise will cause any call to our double's `read()` method with exactly one
+argument - `'123'` to always return `'value'`. But that's only for this
+promise, there's plenty others you can use:
+
+- `ReturnPromise` or `->willReturn(1)` - returns a value from a method call
+- `ReturnArgumentPromise` or `->willReturnArgument($index)` - returns the nth method argument from call
+- `ThrowPromise` or `->willThrow($exception)` - causes the method to throw specific exception
+- `CallbackPromise` or `->will($callback)` - gives you a quick way to define your own custom logic
+
+Keep in mind, that you can always add even more promises by implementing
+`Prophecy\Promise\PromiseInterface`.
+
+#### Method prophecies idempotency
+
+Prophecy enforces same method prophecies and, as a consequence, same promises and
+predictions for the same method calls with the same arguments. This means:
+
+```php
+$methodProphecy1 = $prophecy->read('123');
+$methodProphecy2 = $prophecy->read('123');
+$methodProphecy3 = $prophecy->read('321');
+
+$methodProphecy1 === $methodProphecy2;
+$methodProphecy1 !== $methodProphecy3;
+```
+
+That's interesting, right? Now you might ask me how would you define more complex
+behaviors where some method call changes behavior of others. In PHPUnit or Mockery
+you do that by predicting how many times your method will be called. In Prophecy,
+you'll use promises for that:
+
+```php
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName('everzet')->will(function () {
+    $this->getName()->willReturn('everzet');
+});
+
+// For PHP 5.3
+$user->setName('everzet')->will(function ($args, $user) {
+    $user->getName()->willReturn('everzet');
+});
+
+// Or
+$user->setName('everzet')->will(function ($args) use ($user) {
+    $user->getName()->willReturn('everzet');
+});
+```
+
+And now it doesn't matter how many times or in which order your methods are called.
+What matters is their behaviors and how well you faked it.
+
+#### Arguments wildcarding
+
+The previous example is awesome (at least I hope it is for you), but that's not
+optimal enough. We hardcoded `'everzet'` in our expectation. Isn't there a better
+way? In fact there is, but it involves understanding what this `'everzet'`
+actually is.
+
+You see, even if method arguments used during method prophecy creation look
+like simple method arguments, in reality they are not. They are argument token
+wildcards.  As a matter of fact, `->setName('everzet')` looks like a simple call just
+because Prophecy automatically transforms it under the hood into:
+
+```php
+$user->setName(new Prophecy\Argument\Token\ExactValueToken('everzet'));
+```
+
+Those argument tokens are simple PHP classes, that implement
+`Prophecy\Argument\Token\TokenInterface` and tell Prophecy how to compare real arguments
+with your expectations. And yes, those classnames are damn big. That's why there's a
+shortcut class `Prophecy\Argument`, which you can use to create tokens like that:
+
+```php
+use Prophecy\Argument;
+
+$user->setName(Argument::exact('everzet'));
+```
+
+`ExactValueToken` is not very useful in our case as it forced us to hardcode the username.
+That's why Prophecy comes bundled with a bunch of other tokens:
+
+- `IdenticalValueToken` or `Argument::is($value)` - checks that the argument is identical to a specific value
+- `ExactValueToken` or `Argument::exact($value)` - checks that the argument matches a specific value
+- `TypeToken` or `Argument::type($typeOrClass)` - checks that the argument matches a specific type or
+  classname
+- `ObjectStateToken` or `Argument::which($method, $value)` - checks that the argument method returns
+  a specific value
+- `CallbackToken` or `Argument::that(callback)` - checks that the argument matches a custom callback
+- `AnyValueToken` or `Argument::any()` - matches any argument
+- `AnyValuesToken` or `Argument::cetera()` - matches any arguments to the rest of the signature
+- `StringContainsToken` or `Argument::containingString($value)` - checks that the argument contains a specific string value
+
+And you can add even more by implementing `TokenInterface` with your own custom classes.
+
+So, let's refactor our initial `{set,get}Name()` logic with argument tokens:
+
+```php
+use Prophecy\Argument;
+
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName(Argument::type('string'))->will(function ($args) {
+    $this->getName()->willReturn($args[0]);
+});
+
+// For PHP 5.3
+$user->setName(Argument::type('string'))->will(function ($args, $user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+// Or
+$user->setName(Argument::type('string'))->will(function ($args) use ($user) {
+    $user->getName()->willReturn($args[0]);
+});
+```
+
+That's it. Now our `{set,get}Name()` prophecy will work with any string argument provided to it.
+We've just described how our stub object should behave, even though the original object could have
+no behavior whatsoever.
+
+One last bit about arguments now. You might ask, what happens in case of:
+
+```php
+use Prophecy\Argument;
+
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName(Argument::type('string'))->will(function ($args) {
+    $this->getName()->willReturn($args[0]);
+});
+
+// For PHP 5.3
+$user->setName(Argument::type('string'))->will(function ($args, $user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+// Or
+$user->setName(Argument::type('string'))->will(function ($args) use ($user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+$user->setName(Argument::any())->will(function () {
+});
+```
+
+Nothing. Your stub will continue behaving the way it did before. That's because of how
+arguments wildcarding works. Every argument token type has a different score level, which
+wildcard then uses to calculate the final arguments match score and use the method prophecy
+promise that has the highest score. In this case, `Argument::type()` in case of success
+scores `5` and `Argument::any()` scores `3`. So the type token wins, as does the first
+`setName()` method prophecy and its promise. The simple rule of thumb - more precise token
+always wins.
+
+#### Getting stub objects
+
+Ok, now we know how to define our prophecy method promises, let's get our stub from
+it:
+
+```php
+$stub = $prophecy->reveal();
+```
+
+As you might see, the only difference between how we get dummies and stubs is that with
+stubs we describe every object conversation instead of just agreeing with `null` returns
+(object being *dummy*). As a matter of fact, after you define your first promise
+(method call), Prophecy will force you to define all the communications - it throws
+the `UnexpectedCallException` for any call you didn't describe with object prophecy before
+calling it on a stub.
+
+### Mocks
+
+Now we know how to define doubles without behavior (dummies) and doubles with behavior, but
+no expectations (stubs). What's left is doubles for which we have some expectations. These
+are called mocks and in Prophecy they look almost exactly the same as stubs, except that
+they define *predictions* instead of *promises* on method prophecies:
+
+```php
+$entityManager->flush()->shouldBeCalled();
+```
+
+#### Predictions
+
+The `shouldBeCalled()` method here assigns `CallPrediction` to our method prophecy.
+Predictions are a delayed behavior check for your prophecies. You see, during the entire lifetime
+of your doubles, Prophecy records every single call you're making against it inside your
+code. After that, Prophecy can use this collected information to check if it matches defined
+predictions. You can assign predictions to method prophecies using the
+`MethodProphecy::should(PredictionInterface $prediction)` method. As a matter of fact,
+the `shouldBeCalled()` method we used earlier is just a shortcut to:
+
+```php
+$entityManager->flush()->should(new Prophecy\Prediction\CallPrediction());
+```
+
+It checks if your method of interest (that matches both the method name and the arguments wildcard)
+was called 1 or more times. If the prediction failed then it throws an exception. When does this
+check happen? Whenever you call `checkPredictions()` on the main Prophet object:
+
+```php
+$prophet->checkPredictions();
+```
+
+In PHPUnit, you would want to put this call into the `tearDown()` method. If no predictions
+are defined, it would do nothing. So it won't harm to call it after every test.
+
+There are plenty more predictions you can play with:
+
+- `CallPrediction` or `shouldBeCalled()` - checks that the method has been called 1 or more times
+- `NoCallsPrediction` or `shouldNotBeCalled()` - checks that the method has not been called
+- `CallTimesPrediction` or `shouldBeCalledTimes($count)` - checks that the method has been called
+  `$count` times
+- `CallbackPrediction` or `should($callback)` - checks the method against your own custom callback
+
+Of course, you can always create your own custom prediction any time by implementing
+`PredictionInterface`.
+
+### Spies
+
+The last bit of awesomeness in Prophecy is out-of-the-box spies support. As I said in the previous
+section, Prophecy records every call made during the double's entire lifetime. This means
+you don't need to record predictions in order to check them. You can also do it
+manually by using the `MethodProphecy::shouldHave(PredictionInterface $prediction)` method:
+
+```php
+$em = $prophet->prophesize('Doctrine\ORM\EntityManager');
+
+$controller->createUser($em->reveal());
+
+$em->flush()->shouldHaveBeenCalled();
+```
+
+Such manipulation with doubles is called spying. And with Prophecy it just works.

+# PHP_CodeCoverage
+
+**PHP_CodeCoverage** is a library that provides collection, processing, and rendering functionality for PHP code coverage information.
+
+## Requirements
+
+PHP 5.6 is required but using the latest version of PHP is highly recommended.
+
+### PHP 5
+
+[Xdebug](http://xdebug.org/) is the only source of raw code coverage data supported for PHP 5. Version 2.2.1 of Xdebug is required but using the latest version is highly recommended.
+
+### PHP 7
+
+Version 2.4.0 (or later) of [Xdebug](http://xdebug.org/) as well as [phpdbg](http://phpdbg.com/docs) are supported sources of raw code coverage data for PHP 7.
+
+### HHVM
+
+A version of HHVM that implements the Xdebug API for code coverage (`xdebug_*_code_coverage()`) is required.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phpunit/php-code-coverage
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phpunit/php-code-coverage
+
+## Using the PHP_CodeCoverage API
+
+```php
+<?php
+$coverage = new \SebastianBergmann\CodeCoverage\CodeCoverage;
+$coverage->start('<name of test>');
+
+// ...
+
+$coverage->stop();
+
+$writer = new \SebastianBergmann\CodeCoverage\Report\Clover;
+$writer->process($coverage, '/tmp/clover.xml');
+
+$writer = new \SebastianBergmann\CodeCoverage\Report\Html\Facade;
+$writer->process($coverage, '/tmp/code-coverage-report');
+```

+
+# PHP_Timer
+
+Utility class for timing things, factored out of PHPUnit into a stand-alone component.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phpunit/php-timer
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phpunit/php-timer
+
+## Usage
+
+### Basic Timing
+
+```php
+PHP_Timer::start();
+
+// ...
+
+$time = PHP_Timer::stop();
+var_dump($time);
+
+print PHP_Timer::secondsToTimeString($time);
+```
+
+The code above yields the output below:
+
+    double(1.0967254638672E-5)
+    0 ms
+
+### Resource Consumption Since PHP Startup
+
+```php
+print PHP_Timer::resourceUsage();
+```
+
+The code above yields the output below:
+
+    Time: 0 ms, Memory: 0.50MB

+# PHPUnit_MockObject
+
+**PHPUnit_MockObject** is the default mock object library for PHPUnit.
+
+## Requirements
+
+* PHP 5.6 is required but using the latest version of PHP is highly recommended
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require phpunit/phpunit-mock-objects
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev phpunit/phpunit-mock-objects
+

+# Contributor Code of Conduct
+
+As contributors and maintainers of this project, and in the interest of fostering an open and welcoming community, we pledge to respect all people who contribute through reporting issues, posting feature requests, updating documentation, submitting pull requests or patches, and other activities.
+
+We are committed to making participation in this project a harassment-free experience for everyone, regardless of level of experience, gender, gender identity and expression, sexual orientation, disability, personal appearance, body size, race, ethnicity, age, religion, or nationality.
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery
+* Personal attacks
+* Trolling or insulting/derogatory comments
+* Public or private harassment
+* Publishing other's private information, such as physical or electronic
+  addresses, without explicit permission
+* Other unethical or unprofessional conduct
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+By adopting this Code of Conduct, project maintainers commit themselves to fairly and consistently applying these principles to every aspect of managing this project. Project maintainers who do not follow or enforce the Code of Conduct may be permanently removed from the project team.
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community.
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project maintainer at sebastian@phpunit.de. All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. Maintainers are obligated to maintain confidentiality with regard to the reporter of an incident.
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.3.0, available at [http://contributor-covenant.org/version/1/3/0/][version]

+# Contributing to PHPUnit
+
+## Contributor Code of Conduct
+
+Please note that this project is released with a [Contributor Code of Conduct](CODE_OF_CONDUCT.md). By participating in this project you agree to abide by its terms.
+
+## Workflow
+
+* Fork the project.
+* Make your bug fix or feature addition.
+* Add tests for it. This is important so we don't break it in a future version unintentionally.
+* Send a pull request. Bonus points for topic branches.
+
+Please make sure that you have [set up your user name and email address](http://git-scm.com/book/en/v2/Getting-Started-First-Time-Git-Setup) for use with Git. Strings such as `silly nick name <root@localhost>` look really stupid in the commit history of a project.
+
+Pull requests for bug fixes must be based on the current stable branch whereas pull requests for new features must be based on the `master` branch.
+
+We are trying to keep backwards compatibility breaks in PHPUnit to an absolute minimum. Please take this into account when proposing changes.
+
+Due to time constraints, we are not always able to respond as quickly as we would like. Please do not take delays personal and feel free to remind us if you feel that we forgot to respond.
+
+## Coding Guidelines
+
+This project comes with a configuration file for [php-cs-fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer) (`.php_cs`) that you can use to (re)format your sourcecode for compliance with this project's coding guidelines:
+
+```bash
+$ wget http://cs.sensiolabs.org/download/php-cs-fixer-v2.phar -O php-cs-fixer.phar
+
+$ php php-cs-fixer.phar fix
+```
+
+## Using PHPUnit from a Git checkout
+
+The following commands can be used to perform the initial checkout of PHPUnit:
+
+```bash
+$ git clone git://github.com/sebastianbergmann/phpunit.git
+
+$ cd phpunit
+```
+
+Retrieve PHPUnit's dependencies using [Composer](https://getcomposer.org/):
+
+```bash
+$ composer install
+```
+
+The `phpunit` script can be used to invoke the PHPUnit test runner:
+
+```bash
+$ ./phpunit --version
+```
+
+## Running PHPUnit's own test suite
+
+After following the steps shown above, PHPUnit's own test suite is run like this:
+
+```bash
+$ ./phpunit
+```
+
+## Reporting issues
+
+Please use the most specific issue tracker to search for existing tickets and to open new tickets:
+
+* [General problems](https://github.com/sebastianbergmann/phpunit/issues)
+* [Code Coverage](https://github.com/sebastianbergmann/php-code-coverage/issues)
+* [Stub and Mock Objects](https://github.com/sebastianbergmann/phpunit-mock-objects/issues)
+* [DbUnit](https://github.com/sebastianbergmann/dbunit/issues)
+* [Documentation](https://github.com/sebastianbergmann/phpunit-documentation/issues)
+* [Website](https://github.com/sebastianbergmann/phpunit-website/issues)

+# PHPUnit
+
+PHPUnit is a programmer-oriented testing framework for PHP. It is an instance of the xUnit architecture for unit testing frameworks.
+
+[![Latest Stable Version](https://img.shields.io/packagist/v/phpunit/phpunit.svg?style=flat-square)](https://packagist.org/packages/phpunit/phpunit)
+[![Minimum PHP Version](https://img.shields.io/badge/php-%3E%3D%205.6-8892BF.svg?style=flat-square)](https://php.net/)
+[![Build Status](https://img.shields.io/travis/sebastianbergmann/phpunit/5.7.svg?style=flat-square)](https://phpunit.de/build-status.html)
+
+## Installation
+
+We distribute a [PHP Archive (PHAR)](https://php.net/phar) that has all required (as well as some optional) dependencies of PHPUnit bundled in a single file:
+
+```bash
+$ wget https://phar.phpunit.de/phpunit.phar
+
+$ chmod +x phpunit.phar
+
+$ mv phpunit.phar /usr/local/bin/phpunit
+```
+
+You can also immediately use the PHAR after you have downloaded it, of course:
+
+```bash
+$ wget https://phar.phpunit.de/phpunit.phar
+
+$ php phpunit.phar
+```
+
+Alternatively, you may use [Composer](https://getcomposer.org/) to download and install PHPUnit as well as its dependencies. Please refer to the [documentation](https://phpunit.de/documentation.html) for details on how to do this.

+/**
+ * A TestCase defines the fixture to run multiple tests.
+ *
+ * To define a TestCase
+ *
+ *   1) Implement a subclass of PHPUnit_Framework_TestCase.
+ *   2) Define instance variables that store the state of the fixture.
+ *   3) Initialize the fixture state by overriding setUp().
+ *   4) Clean-up after a test by overriding tearDown().
+ *
+ * Each test runs in its own fixture so there can be no side effects
+ * among test runs.
+ *
+ * Here is an example:
+ *
+ * <code>
+ * <?php
+ * class MathTest extends PHPUnit_Framework_TestCase
+ * {
+ *     public $value1;
+ *     public $value2;
+ *
+ *     protected function setUp()
+ *     {
+ *         $this->value1 = 2;
+ *         $this->value2 = 3;
+ *     }
+ * }
+ * ?>
+ * </code>
+ *
+ * For each test implement a method which interacts with the fixture.
+ * Verify the expected results with assertions specified by calling
+ * assert with a boolean.
+ *
+ * <code>
+ * <?php
+ * public function testPass()
+ * {
+ *     $this->assertTrue($this->value1 + $this->value2 == 5);
+ * }

+# Changelog
+
+All notable changes to this project will be documented in this file, in reverse chronological order by release.
+
+## 1.0.1 - 2016-08-06
+
+### Added
+
+- Nothing.
+
+### Deprecated
+
+- Nothing.
+
+### Removed
+
+- Nothing.
+
+### Fixed
+
+- Updated all `@return self` annotation references in interfaces to use
+  `@return static`, which more closelly follows the semantics of the
+  specification.
+- Updated the `MessageInterface::getHeaders()` return annotation to use the
+  value `string[][]`, indicating the format is a nested array of strings.
+- Updated the `@link` annotation for `RequestInterface::withRequestTarget()`
+  to point to the correct section of RFC 7230.
+- Updated the `ServerRequestInterface::withUploadedFiles()` parameter annotation
+  to add the parameter name (`$uploadedFiles`).
+- Updated a `@throws` annotation for the `UploadedFileInterface::moveTo()`
+  method to correctly reference the method parameter (it was referencing an
+  incorrect parameter name previously).
+
+## 1.0.0 - 2016-05-18
+
+Initial stable release; reflects accepted PSR-7 specification.

+PSR Http Message
+================
+
+This repository holds all interfaces/classes/traits related to
+[PSR-7](http://www.php-fig.org/psr/psr-7/).
+
+Note that this is not a HTTP message implementation of its own. It is merely an
+interface that describes a HTTP message. See the specification for more details.
+
+Usage
+-----
+
+We'll certainly need some stuff in here.

+ * Its primary use is for HTTP requests, but may also be used in other
+ * contexts.
+ *
+ * Instances of this interface are considered immutable; all methods that
+ * might change state MUST be implemented such that they retain the internal
+ * state of the current instance and return an instance that contains the
+ * changed state.
+ *
+ * Typically the Host header will be also be present in the request message.
+ * For server-side requests, the scheme will typically be discoverable in the
+ * server parameters.

+[![Build Status](https://travis-ci.org/sebastianbergmann/comparator.svg?branch=master)](https://travis-ci.org/sebastianbergmann/comparator)
+
+# Comparator
+
+This component provides the functionality to compare PHP values for equality.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/comparator
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/comparator
+
+## Usage
+
+```php
+<?php
+use SebastianBergmann\Comparator\Factory;
+use SebastianBergmann\Comparator\ComparisonFailure;
+
+$date1 = new DateTime('2013-03-29 04:13:35', new DateTimeZone('America/New_York'));
+$date2 = new DateTime('2013-03-29 03:13:35', new DateTimeZone('America/Chicago'));
+
+$factory = new Factory;
+$comparator = $factory->getComparatorFor($date1, $date2);
+
+try {
+    $comparator->assertEquals($date1, $date2);
+    print "Dates match";
+}
+
+catch (ComparisonFailure $failure) {
+    print "Dates don't match";
+}
+```

+# sebastian/diff
+
+Diff implementation for PHP, factored out of PHPUnit into a stand-alone component.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/diff
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/diff
+
+### Usage
+
+The `Differ` class can be used to generate a textual representation of the difference between two strings:
+
+```php
+use SebastianBergmann\Diff\Differ;
+
+$differ = new Differ;
+print $differ->diff('foo', 'bar');
+```
+
+The code above yields the output below:
+
+    --- Original
+    +++ New
+    @@ @@
+    -foo
+    +bar
+
+The `Parser` class can be used to parse a unified diff into an object graph:
+
+```php
+use SebastianBergmann\Diff\Parser;
+use SebastianBergmann\Git;
+
+$git = new Git('/usr/local/src/money');
+
+$diff = $git->getDiff(
+  '948a1a07768d8edd10dcefa8315c1cbeffb31833',
+  'c07a373d2399f3e686234c4f7f088d635eb9641b'
+);
+
+$parser = new Parser;
+
+print_r($parser->parse($diff));
+```
+
+The code above yields the output below:

+# Environment
+
+This component provides functionality that helps writing PHP code that has runtime-specific (PHP / HHVM) execution paths.
+
+[![Latest Stable Version](https://poser.pugx.org/sebastian/environment/v/stable.png)](https://packagist.org/packages/sebastian/environment)
+[![Build Status](https://travis-ci.org/sebastianbergmann/environment.png?branch=master)](https://travis-ci.org/sebastianbergmann/environment)
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/environment
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/environment
+
+## Usage
+
+```php
+<?php
+use SebastianBergmann\Environment\Runtime;
+
+$runtime = new Runtime;
+
+var_dump($runtime->getNameWithVersion());
+var_dump($runtime->getName());
+var_dump($runtime->getVersion());
+var_dump($runtime->getBinary());
+var_dump($runtime->isHHVM());
+var_dump($runtime->isPHP());
+var_dump($runtime->hasXdebug());
+var_dump($runtime->canCollectCodeCoverage());
+```

+Exporter
+========
+
+[![Build Status](https://secure.travis-ci.org/sebastianbergmann/exporter.png?branch=master)](https://travis-ci.org/sebastianbergmann/exporter)
+
+This component provides the functionality to export PHP variables for visualization.
+
+## Usage
+
+Exporting:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+/*
+Exception Object &0000000078de0f0d000000002003a261 (
+    'message' => ''
+    'string' => ''
+    'code' => 0
+    'file' => '/home/sebastianbergmann/test.php'
+    'line' => 34
+    'trace' => Array &0 ()
+    'previous' => null
+)
+*/
+
+print $exporter->export(new Exception);
+```
+
+## Data Types
+
+Exporting simple types:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+// 46
+print $exporter->export(46);
+
+// 4.0
+print $exporter->export(4.0);
+
+// 'hello, world!'
+print $exporter->export('hello, world!');
+
+// false
+print $exporter->export(false);
+
+// NAN
+print $exporter->export(acos(8));
+
+// -INF
+print $exporter->export(log(0));
+
+// null
+print $exporter->export(null);
+
+// resource(13) of type (stream)
+print $exporter->export(fopen('php://stderr', 'w'));
+
+// Binary String: 0x000102030405
+print $exporter->export(chr(0) . chr(1) . chr(2) . chr(3) . chr(4) . chr(5));
+```
+
+Exporting complex types:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+/*
+Array &0 (
+    0 => Array &1 (
+        0 => 1

+    )
+    1 => Array &2 (

+
+/*

+# GlobalState
+
+Snapshotting of global state, factored out of PHPUnit into a stand-alone component.
+
+[![Build Status](https://travis-ci.org/sebastianbergmann/global-state.svg?branch=master)](https://travis-ci.org/sebastianbergmann/global-state)
+
+## Installation
+
+To add this package as a local, per-project dependency to your project, simply add a dependency on `sebastian/global-state` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on GlobalState:
+
+    {
+        "require": {
+            "sebastian/global-state": "1.0.*"
+        }
+    }

+# Version
+
+**Version** is a library that helps with managing the version number of Git-hosted PHP projects.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/version
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/version
+
+## Usage
+
+The constructor of the `SebastianBergmann\Version` class expects two parameters:
+
+* `$release` is the version number of the latest release (`X.Y.Z`, for instance) or the name of the release series (`X.Y`) when no release has been made from that branch / for that release series yet.
+* `$path` is the path to the directory (or a subdirectory thereof) where the sourcecode of the project can be found. Simply passing `__DIR__` here usually suffices.
+
+Apart from the constructor, the `SebastianBergmann\Version` class has a single public method: `getVersion()`.
+
+Here is a contrived example that shows the basic usage:
+
+    <?php
+    $version = new SebastianBergmann\Version(
+      '3.7.10', '/usr/local/src/phpunit'
+    );
+
+    var_dump($version->getVersion());
+    ?>
+
+    string(18) "3.7.10-17-g00f3408"
+
+When a new release is prepared, the string that is passed to the constructor as the first argument needs to be updated.
+
+### How SebastianBergmann\Version::getVersion() works
+
+* If `$path` is not (part of) a Git repository and `$release` is in `X.Y.Z` format then `$release` is returned as-is.
+* If `$path` is not (part of) a Git repository and `$release` is in `X.Y` format then `$release` is returned suffixed with `-dev`.
+* If `$path` is (part of) a Git repository and `$release` is in `X.Y.Z` format then the output of `git describe --tags` is returned as-is.
+* If `$path` is (part of) a Git repository and `$release` is in `X.Y` format then a string is returned that begins with `X.Y` and ends with information from `git describe --tags`.

+CHANGELOG
+=========
+
+4.0.0
+-----
+
+ * The behavior of the non-specific tag `!` is changed and now forces
+   non-evaluating your values.
+ * complex mappings will throw a `ParseException`
+ * support for the comma as a group separator for floats has been dropped, use
+   the underscore instead
+ * support for the `!!php/object` tag has been dropped, use the `!php/object`
+   tag instead
+ * duplicate mapping keys throw a `ParseException`
+ * non-string mapping keys throw a `ParseException`, use the `Yaml::PARSE_KEYS_AS_STRINGS`
+   flag to cast them to strings
+ * `%` at the beginning of an unquoted string throw a `ParseException`
+ * mappings with a colon (`:`) that is not followed by a whitespace throw a
+   `ParseException`
+ * the `Dumper::setIndentation()` method has been removed
+ * being able to pass boolean options to the `Yaml::parse()`, `Yaml::dump()`,
+   `Parser::parse()`, and `Dumper::dump()` methods to configure the behavior of
+   the parser and dumper is no longer supported, pass bitmask flags instead
+ * the constructor arguments of the `Parser` class have been removed
+ * the `Inline` class is internal and no longer part of the BC promise
+ * removed support for the `!str` tag, use the `!!str` tag instead
+ * added support for tagged scalars.
+
+   ```yml
+   Yaml::parse('!foo bar', Yaml::PARSE_CUSTOM_TAGS);
+   // returns TaggedValue('foo', 'bar');
+   ```
+
+3.4.0
+-----
+
+ * added support for parsing YAML files using the `Yaml::parseFile()` or `Parser::parseFile()` method
+
+ * the `Dumper`, `Parser`, and `Yaml` classes are marked as final
+
+ * Deprecated the `!php/object:` tag which will be replaced by the
+   `!php/object` tag (without the colon) in 4.0.
+
+ * Deprecated the `!php/const:` tag which will be replaced by the
+   `!php/const` tag (without the colon) in 4.0.
+
+ * Support for the `!str` tag is deprecated, use the `!!str` tag instead.
+
+ * Deprecated using the non-specific tag `!` as its behavior will change in 4.0.
+   It will force non-evaluating your values in 4.0. Use plain integers or `!!float` instead.
+
+3.3.0
+-----
+
+ * Starting an unquoted string with a question mark followed by a space is
+   deprecated and will throw a `ParseException` in Symfony 4.0.
+
+ * Deprecated support for implicitly parsing non-string mapping keys as strings.
+   Mapping keys that are no strings will lead to a `ParseException` in Symfony
+   4.0. Use quotes to opt-in for keys to be parsed as strings.
+
+   Before:
+
+   ```php
+   $yaml = <<<YAML
+   null: null key
+   true: boolean true
+   2.0: float key
+   YAML;
+
+   Yaml::parse($yaml);
+   ```
+
+   After:
+
+   ```php
+
+   $yaml = <<<YAML
+   "null": null key
+   "true": boolean true
+   "2.0": float key
+   YAML;
+
+   Yaml::parse($yaml);
+   ```
+
+ * Omitted mapping values will be parsed as `null`.
+
+ * Omitting the key of a mapping is deprecated and will throw a `ParseException` in Symfony 4.0.
+
+ * Added support for dumping empty PHP arrays as YAML sequences:
+
+   ```php
+   Yaml::dump([], 0, 0, Yaml::DUMP_EMPTY_ARRAY_AS_SEQUENCE);
+   ```
+
+3.2.0
+-----
+
+ * Mappings with a colon (`:`) that is not followed by a whitespace are deprecated
+   when the mapping key is not quoted and will lead to a `ParseException` in
+   Symfony 4.0 (e.g. `foo:bar` must be `foo: bar`).
+
+ * Added support for parsing PHP constants:
+
+   ```php
+   Yaml::parse('!php/const:PHP_INT_MAX', Yaml::PARSE_CONSTANT);
+   ```
+
+ * Support for silently ignoring duplicate mapping keys in YAML has been
+   deprecated and will lead to a `ParseException` in Symfony 4.0.
+
+3.1.0
+-----
+
+ * Added support to dump `stdClass` and `ArrayAccess` objects as YAML mappings
+   through the `Yaml::DUMP_OBJECT_AS_MAP` flag.
+
+ * Strings that are not UTF-8 encoded will be dumped as base64 encoded binary
+   data.
+
+ * Added support for dumping multi line strings as literal blocks.
+
+ * Added support for parsing base64 encoded binary data when they are tagged
+   with the `!!binary` tag.
+
+ * Added support for parsing timestamps as `\DateTime` objects:
+
+   ```php
+   Yaml::parse('2001-12-15 21:59:43.10 -5', Yaml::PARSE_DATETIME);
+   ```
+
+ * `\DateTime` and `\DateTimeImmutable` objects are dumped as YAML timestamps.
+
+ * Deprecated usage of `%` at the beginning of an unquoted string.
+
+ * Added support for customizing the YAML parser behavior through an optional bit field:
+
+   ```php
+   Yaml::parse('{ "foo": "bar", "fiz": "cat" }', Yaml::PARSE_EXCEPTION_ON_INVALID_TYPE | Yaml::PARSE_OBJECT | Yaml::PARSE_OBJECT_FOR_MAP);
+   ```
+
+ * Added support for customizing the dumped YAML string through an optional bit field:
+
+   ```php
+   Yaml::dump(array('foo' => new A(), 'bar' => 1), 0, 0, Yaml::DUMP_EXCEPTION_ON_INVALID_TYPE | Yaml::DUMP_OBJECT);
+   ```
+
+3.0.0
+-----
+
+ * Yaml::parse() now throws an exception when a blackslash is not escaped
+   in double-quoted strings
+
+2.8.0
+-----
+
+ * Deprecated usage of a colon in an unquoted mapping value
+ * Deprecated usage of @, \`, | and > at the beginning of an unquoted string
+ * When surrounding strings with double-quotes, you must now escape `\` characters. Not
+   escaping those characters (when surrounded by double-quotes) is deprecated.
+
+   Before:
+
+   ```yml
+   class: "Foo\Var"
+   ```
+
+   After:
+
+   ```yml
+   class: "Foo\\Var"
+   ```
+
+2.1.0
+-----
+
+ * Yaml::parse() does not evaluate loaded files as PHP files by default
+   anymore (call Yaml::enablePhpParsing() to get back the old behavior)

+Webmozart Assert

+[![Build status](https://ci.appveyor.com/api/projects/status/lyg83bcsisrr94se/branch/master?svg=true)](https://ci.appveyor.com/project/webmozart/assert/branch/master)
+[![Latest Stable Version](https://poser.pugx.org/webmozart/assert/v/stable.svg)](https://packagist.org/packages/webmozart/assert)
+[![Total Downloads](https://poser.pugx.org/webmozart/assert/downloads.svg)](https://packagist.org/packages/webmozart/assert)
+[![Dependency Status](https://www.versioneye.com/php/webmozart:assert/1.2.0/badge.svg)](https://www.versioneye.com/php/webmozart:assert/1.2.0)
+
+Latest release: [1.2.0](https://packagist.org/packages/webmozart/assert#1.2.0)
+
+PHP >= 5.3.9
+
+This library contains efficient assertions to test the input and output of
+your methods. With these assertions, you can greatly reduce the amount of coding
+needed to write a safe implementation.
+
+All assertions in the [`Assert`] class throw an `\InvalidArgumentException` if 
+they fail.
+
+FAQ
+---
+
+**What's the difference to [beberlei/assert]?**
+
+This library is heavily inspired by Benjamin Eberlei's wonderful [assert package],
+but fixes a usability issue with error messages that can't be fixed there without
+breaking backwards compatibility.
+
+This package features usable error messages by default. However, you can also 
+easily write custom error messages:
+
+```
+Assert::string($path, 'The path is expected to be a string. Got: %s');
+```
+
+In [beberlei/assert], the ordering of the `%s` placeholders is different for 
+every assertion. This package, on the contrary, provides consistent placeholder 
+ordering for all assertions:
+
+* `%s`: The tested value as string, e.g. `"/foo/bar"`.
+* `%2$s`, `%3$s`, ...: Additional assertion-specific values, e.g. the
+  minimum/maximum length, allowed values, etc.
+  
+Check the source code of the assertions to find out details about the additional
+available placeholders.
+
+Installation
+------------
+
+Use [Composer] to install the package:
+
+```
+$ composer require webmozart/assert
+```
+
+Example
+-------
+
+```php
+use Webmozart\Assert\Assert;
+
+class Employee
+{
+    public function __construct($id)
+    {
+        Assert::integer($id, 'The employee ID must be an integer. Got: %s');
+        Assert::greaterThan($id, 0, 'The employee ID must be a positive integer. Got: %s');
+    }
+}
+```
+
+If you create an employee with an invalid ID, an exception is thrown:
+
+```php
+new Employee('foobar');
+// => InvalidArgumentException: 
+//    The employee ID must be an integer. Got: string
+
+new Employee(-10);
+// => InvalidArgumentException: 
+//    The employee ID must be a positive integer. Got: -10
+```
+
