+					GNU GENERAL PUBLIC LICENSE

+						Version 3, 29 June 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 General Public License is a free, copyleft license for

+	software and other kinds of works.

+

+		The licenses for most software and other practical works are designed

+	to take away your freedom to share and change the works. By contrast,

+	the GNU General Public License is 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. We, the Free Software Foundation, use the

+	GNU General Public License for most of our software; it applies also to

+	any other work released this way by its authors. You can apply it to

+	your programs, too.

+

+		When we speak of free software, we are referring to freedom, not

+	price. Our General Public Licenses are designed to make sure that you

+	have the freedom to distribute copies of free software (and charge for

+	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.

+

+		To protect your rights, we need to prevent others from denying you

+	these rights or asking you to surrender the rights. Therefore, you have

+	certain responsibilities if you distribute copies of the software, or if

+	you modify it: responsibilities to respect the freedom of others.

+

+		For example, if you distribute copies of such a program, whether

+	gratis or for a fee, you must pass on to the recipients the same

+	freedoms that you received. You must make sure that they, too, receive

+	or can get the source code. And you must show them these terms so they

+	know their rights.

+

+		Developers that use the GNU GPL protect your rights with two steps:

+	(1) assert copyright on the software, and (2) offer you this License

+	giving you legal permission to copy, distribute and/or modify it.

+

+		For the developers' and authors' protection, the GPL clearly explains

+	that there is no warranty for this free software. For both users' and

+	authors' sake, the GPL requires that modified versions be marked as

+	changed, so that their problems will not be attributed erroneously to

+	authors of previous versions.

+

+		Some devices are designed to deny users access to install or run

+	modified versions of the software inside them, although the manufacturer

+	can do so. This is fundamentally incompatible with the aim of

+	protecting users' freedom to change the software. The systematic

+	pattern of such abuse occurs in the area of products for individuals to

+	use, which is precisely where it is most unacceptable. Therefore, we

+	have designed this version of the GPL to prohibit the practice for those

+	products. If such problems arise substantially in other domains, we

+	stand ready to extend this provision to those domains in future versions

+	of the GPL, as needed to protect the freedom of users.

+

+		Finally, every program is threatened constantly by software patents.

+	States should not allow patents to restrict development and use of

+	software on general-purpose computers, but in those that do, we wish to

+	avoid the special danger that patents applied to a free program could

+	make it effectively proprietary. To prevent this, the GPL assures that

+	patents cannot be used to render the program non-free.

+

+		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 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. Use with the GNU Affero General Public License.

+

+		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 Affero 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 special requirements of the GNU Affero General Public License,

+	section 13, concerning interaction through a network will apply to the

+	combination as such.

+

+		14. Revised Versions of this License.

+

+		The Free Software Foundation may publish revised and/or new versions of

+	the GNU 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 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 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 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

+	WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS

+	THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY

+	GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE

+	USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF

+	DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD

+	PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),

+	EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF

+	SUCH DAMAGES.

+

+		17. Interpretation of Sections 15 and 16.

+

+		If the disclaimer of warranty and limitation of liability provided

+	above cannot be given local legal effect according to their terms,

+	reviewing courts shall apply local law that most closely approximates

+	an absolute waiver of all civil liability in connection with the

+	Program, unless a warranty or assumption of liability accompanies a

+	copy of the Program in return for a fee.

+

+						END OF TERMS AND CONDITIONS

+

+				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.

+

+		xmpp library for Python.

+		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 the program does terminal interaction, make it output a short

+	might be different; for a GUI interface, you would use an "about box".

+

+		You should also get your employer (if you work as a programmer) or school,
