		14	<p style="text-align: center;">Version 3, 29 June 2007</p>
		15
		16	<p>Copyright © 2007 Free Software Foundation, Inc.
		17	<<a href="https://fsf.org/">https://fsf.org/</a>></p><p>
		18	Everyone is permitted to copy and distribute verbatim copies
		19	of this license document, but changing it is not allowed.</p>
		20
		21	<h3><a name="preamble"></a>Preamble</h3>
		22
		23	<p>The GNU General Public License is a free, copyleft license for
		24	software and other kinds of works.</p>
		25
		26	<p>The licenses for most software and other practical works are designed
		27	to take away your freedom to share and change the works. By contrast,
		28	the GNU General Public License is intended to guarantee your freedom to
		29	share and change all versions of a program--to make sure it remains free
		30	software for all its users. We, the Free Software Foundation, use the
		31	GNU General Public License for most of our software; it applies also to
		32	any other work released this way by its authors. You can apply it to
		33	your programs, too.</p>
		34
		35	<p>When we speak of free software, we are referring to freedom, not
		36	price. Our General Public Licenses are designed to make sure that you
		37	have the freedom to distribute copies of free software (and charge for
		38	them if you wish), that you receive source code or can get it if you
		39	want it, that you can change the software or use pieces of it in new
		40	free programs, and that you know you can do these things.</p>
		41
		42	<p>To protect your rights, we need to prevent others from denying you
		43	these rights or asking you to surrender the rights. Therefore, you have
		44	certain responsibilities if you distribute copies of the software, or if
		45	you modify it: responsibilities to respect the freedom of others.</p>
		46
		47	<p>For example, if you distribute copies of such a program, whether
		48	gratis or for a fee, you must pass on to the recipients the same
		49	freedoms that you received. You must make sure that they, too, receive
		50	or can get the source code. And you must show them these terms so they
		51	know their rights.</p>
		52
		53	<p>Developers that use the GNU GPL protect your rights with two steps:
		54	(1) assert copyright on the software, and (2) offer you this License
		55	giving you legal permission to copy, distribute and/or modify it.</p>
		56
		57	<p>For the developers' and authors' protection, the GPL clearly explains
		58	that there is no warranty for this free software. For both users' and
		59	authors' sake, the GPL requires that modified versions be marked as
		60	changed, so that their problems will not be attributed erroneously to
		61	authors of previous versions.</p>
		62
		63	<p>Some devices are designed to deny users access to install or run
		64	modified versions of the software inside them, although the manufacturer
		65	can do so. This is fundamentally incompatible with the aim of
		66	protecting users' freedom to change the software. The systematic
		67	pattern of such abuse occurs in the area of products for individuals to
		68	use, which is precisely where it is most unacceptable. Therefore, we
		69	have designed this version of the GPL to prohibit the practice for those
		70	products. If such problems arise substantially in other domains, we
		71	stand ready to extend this provision to those domains in future versions
		72	of the GPL, as needed to protect the freedom of users.</p>
		73
		74	<p>Finally, every program is threatened constantly by software patents.
		75	States should not allow patents to restrict development and use of
		76	software on general-purpose computers, but in those that do, we wish to
		77	avoid the special danger that patents applied to a free program could
		78	make it effectively proprietary. To prevent this, the GPL assures that
		79	patents cannot be used to render the program non-free.</p>
		80
		81	<p>The precise terms and conditions for copying, distribution and
		82	modification follow.</p>
		83
		84	<h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
		85
		86	<h4><a name="section0"></a>0. Definitions.</h4>
		87
		88	<p>“This License” refers to version 3 of the GNU General Public License.</p>
		89
		90	<p>“Copyright” also means copyright-like laws that apply to other kinds of
		91	works, such as semiconductor masks.</p>
		92
		93	<p>“The Program” refers to any copyrightable work licensed under this
		94	License. Each licensee is addressed as “you”. “Licensees” and
		95	“recipients” may be individuals or organizations.</p>
		96
		97	<p>To “modify” a work means to copy from or adapt all or part of the work
		98	in a fashion requiring copyright permission, other than the making of an
		99	exact copy. The resulting work is called a “modified version” of the
		100	earlier work or a work “based on” the earlier work.</p>
		101
		102	<p>A “covered work” means either the unmodified Program or a work based
		103	on the Program.</p>
		104
		105	<p>To “propagate” a work means to do anything with it that, without
		106	permission, would make you directly or secondarily liable for
		107	infringement under applicable copyright law, except executing it on a
		108	computer or modifying a private copy. Propagation includes copying,
		109	distribution (with or without modification), making available to the
		110	public, and in some countries other activities as well.</p>
		111
		112	<p>To “convey” a work means any kind of propagation that enables other
		113	parties to make or receive copies. Mere interaction with a user through
		114	a computer network, with no transfer of a copy, is not conveying.</p>
		115
		116	<p>An interactive user interface displays “Appropriate Legal Notices”
		117	to the extent that it includes a convenient and prominently visible
		118	feature that (1) displays an appropriate copyright notice, and (2)
		119	tells the user that there is no warranty for the work (except to the
		120	extent that warranties are provided), that licensees may convey the
		121	work under this License, and how to view a copy of this License. If
		122	the interface presents a list of user commands or options, such as a
		123	menu, a prominent item in the list meets this criterion.</p>
		124
		125	<h4><a name="section1"></a>1. Source Code.</h4>
		126
		127	<p>The “source code” for a work means the preferred form of the work
		128	for making modifications to it. “Object code” means any non-source
		129	form of a work.</p>
		130
		131	<p>A “Standard Interface” means an interface that either is an official
		132	standard defined by a recognized standards body, or, in the case of
		133	interfaces specified for a particular programming language, one that
		134	is widely used among developers working in that language.</p>
		135
		136	<p>The “System Libraries” of an executable work include anything, other
		137	than the work as a whole, that (a) is included in the normal form of
		138	packaging a Major Component, but which is not part of that Major
		139	Component, and (b) serves only to enable use of the work with that
		140	Major Component, or to implement a Standard Interface for which an
		141	implementation is available to the public in source code form. A
		142	“Major Component”, in this context, means a major essential component
		143	(kernel, window system, and so on) of the specific operating system
		144	(if any) on which the executable work runs, or a compiler used to
		145	produce the work, or an object code interpreter used to run it.</p>
		146
		147	<p>The “Corresponding Source” for a work in object code form means all
		148	the source code needed to generate, install, and (for an executable
		149	work) run the object code and to modify the work, including scripts to
		150	control those activities. However, it does not include the work's
		151	System Libraries, or general-purpose tools or generally available free
		152	programs which are used unmodified in performing those activities but
		153	which are not part of the work. For example, Corresponding Source
		154	includes interface definition files associated with source files for
		155	the work, and the source code for shared libraries and dynamically
		156	linked subprograms that the work is specifically designed to require,
		157	such as by intimate data communication or control flow between those
		158	subprograms and other parts of the work.</p>
		159
		160	<p>The Corresponding Source need not include anything that users
		161	can regenerate automatically from other parts of the Corresponding
		162	Source.</p>
		163
		164	<p>The Corresponding Source for a work in source code form is that
		165	same work.</p>
		166
		167	<h4><a name="section2"></a>2. Basic Permissions.</h4>
		168
		169	<p>All rights granted under this License are granted for the term of
		170	copyright on the Program, and are irrevocable provided the stated
		171	conditions are met. This License explicitly affirms your unlimited
		172	permission to run the unmodified Program. The output from running a
		173	covered work is covered by this License only if the output, given its
		174	content, constitutes a covered work. This License acknowledges your
		175	rights of fair use or other equivalent, as provided by copyright law.</p>
		176
		177	<p>You may make, run and propagate covered works that you do not
		178	convey, without conditions so long as your license otherwise remains
		179	in force. You may convey covered works to others for the sole purpose
		180	of having them make modifications exclusively for you, or provide you
		181	with facilities for running those works, provided that you comply with
		182	the terms of this License in conveying all material for which you do
		183	not control copyright. Those thus making or running the covered works
		184	for you must do so exclusively on your behalf, under your direction
		185	and control, on terms that prohibit them from making any copies of
		186	your copyrighted material outside their relationship with you.</p>
		187
		188	<p>Conveying under any other circumstances is permitted solely under
		189	the conditions stated below. Sublicensing is not allowed; section 10
		190	makes it unnecessary.</p>
		191
		192	<h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
		193
		194	<p>No covered work shall be deemed part of an effective technological
		195	measure under any applicable law fulfilling obligations under article
		196	11 of the WIPO copyright treaty adopted on 20 December 1996, or
		197	similar laws prohibiting or restricting circumvention of such
		198	measures.</p>
		199
		200	<p>When you convey a covered work, you waive any legal power to forbid
		201	circumvention of technological measures to the extent such circumvention
		202	is effected by exercising rights under this License with respect to
		203	the covered work, and you disclaim any intention to limit operation or
		204	modification of the work as a means of enforcing, against the work's
		205	users, your or third parties' legal rights to forbid circumvention of
		206	technological measures.</p>
		207
		208	<h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
		209
		210	<p>You may convey verbatim copies of the Program's source code as you
		211	receive it, in any medium, provided that you conspicuously and
		212	appropriately publish on each copy an appropriate copyright notice;
		213	keep intact all notices stating that this License and any
		214	non-permissive terms added in accord with section 7 apply to the code;
		215	keep intact all notices of the absence of any warranty; and give all
		216	recipients a copy of this License along with the Program.</p>
		217
		218	<p>You may charge any price or no price for each copy that you convey,
		219	and you may offer support or warranty protection for a fee.</p>
		220
		221	<h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
		222
		223	<p>You may convey a work based on the Program, or the modifications to
		224	produce it from the Program, in the form of source code under the
		225	terms of section 4, provided that you also meet all of these conditions:</p>
		226
		227	<ul>
		228	<li>a) The work must carry prominent notices stating that you modified
		229	it, and giving a relevant date.</li>
		230
		231	<li>b) The work must carry prominent notices stating that it is
		232	released under this License and any conditions added under section
		233	7. This requirement modifies the requirement in section 4 to
		234	“keep intact all notices”.</li>
		235
		236	<li>c) You must license the entire work, as a whole, under this
		237	License to anyone who comes into possession of a copy. This
		238	License will therefore apply, along with any applicable section 7
		239	additional terms, to the whole of the work, and all its parts,
		240	regardless of how they are packaged. This License gives no
		241	permission to license the work in any other way, but it does not
		242	invalidate such permission if you have separately received it.</li>
		243
		244	<li>d) If the work has interactive user interfaces, each must display
		245	Appropriate Legal Notices; however, if the Program has interactive
		246	interfaces that do not display Appropriate Legal Notices, your
		247	work need not make them do so.</li>
		248	</ul>
		249
		250	<p>A compilation of a covered work with other separate and independent
		251	works, which are not by their nature extensions of the covered work,
		252	and which are not combined with it such as to form a larger program,
		253	in or on a volume of a storage or distribution medium, is called an
		254	“aggregate” if the compilation and its resulting copyright are not
		255	used to limit the access or legal rights of the compilation's users
		256	beyond what the individual works permit. Inclusion of a covered work
		257	in an aggregate does not cause this License to apply to the other
		258	parts of the aggregate.</p>
		259
		260	<h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
		261
		262	<p>You may convey a covered work in object code form under the terms
		263	of sections 4 and 5, provided that you also convey the
		264	machine-readable Corresponding Source under the terms of this License,
		265	in one of these ways:</p>
		266
		267	<ul>
		268	<li>a) Convey the object code in, or embodied in, a physical product
		269	(including a physical distribution medium), accompanied by the
		270	Corresponding Source fixed on a durable physical medium
		271	customarily used for software interchange.</li>
		272
		273	<li>b) Convey the object code in, or embodied in, a physical product
		274	(including a physical distribution medium), accompanied by a
		275	written offer, valid for at least three years and valid for as
		276	long as you offer spare parts or customer support for that product
		277	model, to give anyone who possesses the object code either (1) a
		278	copy of the Corresponding Source for all the software in the
		279	product that is covered by this License, on a durable physical
		280	medium customarily used for software interchange, for a price no
		281	more than your reasonable cost of physically performing this
		282	conveying of source, or (2) access to copy the
		283	Corresponding Source from a network server at no charge.</li>
		284
		285	<li>c) Convey individual copies of the object code with a copy of the
		286	written offer to provide the Corresponding Source. This
		287	alternative is allowed only occasionally and noncommercially, and
		288	only if you received the object code with such an offer, in accord
		289	with subsection 6b.</li>
		290
		291	<li>d) Convey the object code by offering access from a designated
		292	place (gratis or for a charge), and offer equivalent access to the
		293	Corresponding Source in the same way through the same place at no
		294	further charge. You need not require recipients to copy the
		295	Corresponding Source along with the object code. If the place to
		296	copy the object code is a network server, the Corresponding Source
		297	may be on a different server (operated by you or a third party)
		298	that supports equivalent copying facilities, provided you maintain
		299	clear directions next to the object code saying where to find the
		300	Corresponding Source. Regardless of what server hosts the
		301	Corresponding Source, you remain obligated to ensure that it is
		302	available for as long as needed to satisfy these requirements.</li>
		303
		304	<li>e) Convey the object code using peer-to-peer transmission, provided
		305	you inform other peers where the object code and Corresponding
		306	Source of the work are being offered to the general public at no
		307	charge under subsection 6d.</li>
		308	</ul>
		309
		310	<p>A separable portion of the object code, whose source code is excluded
		311	from the Corresponding Source as a System Library, need not be
		312	included in conveying the object code work.</p>
		313
		314	<p>A “User Product” is either (1) a “consumer product”, which means any
		315	tangible personal property which is normally used for personal, family,
		316	or household purposes, or (2) anything designed or sold for incorporation
		317	into a dwelling. In determining whether a product is a consumer product,
		318	doubtful cases shall be resolved in favor of coverage. For a particular
		319	product received by a particular user, “normally used” refers to a
		320	typical or common use of that class of product, regardless of the status
		321	of the particular user or of the way in which the particular user
		322	actually uses, or expects or is expected to use, the product. A product
		323	is a consumer product regardless of whether the product has substantial
		324	commercial, industrial or non-consumer uses, unless such uses represent
		325	the only significant mode of use of the product.</p>
		326
		327	<p>“Installation Information” for a User Product means any methods,
		328	procedures, authorization keys, or other information required to install
		329	and execute modified versions of a covered work in that User Product from
		330	a modified version of its Corresponding Source. The information must
		331	suffice to ensure that the continued functioning of the modified object
		332	code is in no case prevented or interfered with solely because
		333	modification has been made.</p>
		334
		335	<p>If you convey an object code work under this section in, or with, or
		336	specifically for use in, a User Product, and the conveying occurs as
		337	part of a transaction in which the right of possession and use of the
		338	User Product is transferred to the recipient in perpetuity or for a
		339	fixed term (regardless of how the transaction is characterized), the
		340	Corresponding Source conveyed under this section must be accompanied
		341	by the Installation Information. But this requirement does not apply
		342	if neither you nor any third party retains the ability to install
		343	modified object code on the User Product (for example, the work has
		344	been installed in ROM).</p>
		345
		346	<p>The requirement to provide Installation Information does not include a
		347	requirement to continue to provide support service, warranty, or updates
		348	for a work that has been modified or installed by the recipient, or for
		349	the User Product in which it has been modified or installed. Access to a
		350	network may be denied when the modification itself materially and
		351	adversely affects the operation of the network or violates the rules and
		352	protocols for communication across the network.</p>
		353
		354	<p>Corresponding Source conveyed, and Installation Information provided,
		355	in accord with this section must be in a format that is publicly
		356	documented (and with an implementation available to the public in
		357	source code form), and must require no special password or key for
		358	unpacking, reading or copying.</p>
		359
		360	<h4><a name="section7"></a>7. Additional Terms.</h4>
		361
		362	<p>“Additional permissions” are terms that supplement the terms of this
		363	License by making exceptions from one or more of its conditions.
		364	Additional permissions that are applicable to the entire Program shall
		365	be treated as though they were included in this License, to the extent
		366	that they are valid under applicable law. If additional permissions
		367	apply only to part of the Program, that part may be used separately
		368	under those permissions, but the entire Program remains governed by
		369	this License without regard to the additional permissions.</p>
		370
		371	<p>When you convey a copy of a covered work, you may at your option
		372	remove any additional permissions from that copy, or from any part of
		373	it. (Additional permissions may be written to require their own
		374	removal in certain cases when you modify the work.) You may place
		375	additional permissions on material, added by you to a covered work,
		376	for which you have or can give appropriate copyright permission.</p>
		377
		378	<p>Notwithstanding any other provision of this License, for material you
		379	add to a covered work, you may (if authorized by the copyright holders of
		380	that material) supplement the terms of this License with terms:</p>
		381
		382	<ul>
		383	<li>a) Disclaiming warranty or limiting liability differently from the
		384	terms of sections 15 and 16 of this License; or</li>
		385
		386	<li>b) Requiring preservation of specified reasonable legal notices or
		387	author attributions in that material or in the Appropriate Legal
		388	Notices displayed by works containing it; or</li>
		389
		390	<li>c) Prohibiting misrepresentation of the origin of that material, or
		391	requiring that modified versions of such material be marked in
		392	reasonable ways as different from the original version; or</li>
		393
		394	<li>d) Limiting the use for publicity purposes of names of licensors or
		395	authors of the material; or</li>
		396
		397	<li>e) Declining to grant rights under trademark law for use of some
		398	trade names, trademarks, or service marks; or</li>
		399
		400	<li>f) Requiring indemnification of licensors and authors of that
		401	material by anyone who conveys the material (or modified versions of
		402	it) with contractual assumptions of liability to the recipient, for
		403	any liability that these contractual assumptions directly impose on
		404	those licensors and authors.</li>
		405	</ul>
		406
		407	<p>All other non-permissive additional terms are considered “further
		408	restrictions” within the meaning of section 10. If the Program as you
		409	received it, or any part of it, contains a notice stating that it is
		410	governed by this License along with a term that is a further
		411	restriction, you may remove that term. If a license document contains
		412	a further restriction but permits relicensing or conveying under this
		413	License, you may add to a covered work material governed by the terms
		414	of that license document, provided that the further restriction does
		415	not survive such relicensing or conveying.</p>
		416
		417	<p>If you add terms to a covered work in accord with this section, you
		418	must place, in the relevant source files, a statement of the
		419	additional terms that apply to those files, or a notice indicating
		420	where to find the applicable terms.</p>
		421
		422	<p>Additional terms, permissive or non-permissive, may be stated in the
		423	form of a separately written license, or stated as exceptions;
		424	the above requirements apply either way.</p>
		425
		426	<h4><a name="section8"></a>8. Termination.</h4>
		427
		428	<p>You may not propagate or modify a covered work except as expressly
		429	provided under this License. Any attempt otherwise to propagate or
		430	modify it is void, and will automatically terminate your rights under
		431	this License (including any patent licenses granted under the third
		432	paragraph of section 11).</p>
		433
		434	<p>However, if you cease all violation of this License, then your
		435	license from a particular copyright holder is reinstated (a)
		436	provisionally, unless and until the copyright holder explicitly and
		437	finally terminates your license, and (b) permanently, if the copyright
		438	holder fails to notify you of the violation by some reasonable means
		439	prior to 60 days after the cessation.</p>
		440
		441	<p>Moreover, your license from a particular copyright holder is
		442	reinstated permanently if the copyright holder notifies you of the
		443	violation by some reasonable means, this is the first time you have
		444	received notice of violation of this License (for any work) from that
		445	copyright holder, and you cure the violation prior to 30 days after
		446	your receipt of the notice.</p>
		447
		448	<p>Termination of your rights under this section does not terminate the
		449	licenses of parties who have received copies or rights from you under
		450	this License. If your rights have been terminated and not permanently
		451	reinstated, you do not qualify to receive new licenses for the same
		452	material under section 10.</p>
		453
		454	<h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
		455
		456	<p>You are not required to accept this License in order to receive or
		457	run a copy of the Program. Ancillary propagation of a covered work
		458	occurring solely as a consequence of using peer-to-peer transmission
		459	to receive a copy likewise does not require acceptance. However,
		460	nothing other than this License grants you permission to propagate or
		461	modify any covered work. These actions infringe copyright if you do
		462	not accept this License. Therefore, by modifying or propagating a
		463	covered work, you indicate your acceptance of this License to do so.</p>
		464
		465	<h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
		466
		467	<p>Each time you convey a covered work, the recipient automatically
		468	receives a license from the original licensors, to run, modify and
		469	propagate that work, subject to this License. You are not responsible
		470	for enforcing compliance by third parties with this License.</p>
		471
		472	<p>An “entity transaction” is a transaction transferring control of an
		473	organization, or substantially all assets of one, or subdividing an
		474	organization, or merging organizations. If propagation of a covered
		475	work results from an entity transaction, each party to that
		476	transaction who receives a copy of the work also receives whatever
		477	licenses to the work the party's predecessor in interest had or could
		478	give under the previous paragraph, plus a right to possession of the
		479	Corresponding Source of the work from the predecessor in interest, if
		480	the predecessor has it or can get it with reasonable efforts.</p>
		481
		482	<p>You may not impose any further restrictions on the exercise of the
		483	rights granted or affirmed under this License. For example, you may
		484	not impose a license fee, royalty, or other charge for exercise of
		485	rights granted under this License, and you may not initiate litigation
		486	(including a cross-claim or counterclaim in a lawsuit) alleging that
		487	any patent claim is infringed by making, using, selling, offering for
		488	sale, or importing the Program or any portion of it.</p>
		489
		490	<h4><a name="section11"></a>11. Patents.</h4>
		491
		492	<p>A “contributor” is a copyright holder who authorizes use under this
		493	License of the Program or a work on which the Program is based. The
		494	work thus licensed is called the contributor's “contributor version”.</p>
		495
		496	<p>A contributor's “essential patent claims” are all patent claims
		497	owned or controlled by the contributor, whether already acquired or
		498	hereafter acquired, that would be infringed by some manner, permitted
		499	by this License, of making, using, or selling its contributor version,
		500	but do not include claims that would be infringed only as a
		501	consequence of further modification of the contributor version. For
		502	purposes of this definition, “control” includes the right to grant
		503	patent sublicenses in a manner consistent with the requirements of
		504	this License.</p>
		505
		506	<p>Each contributor grants you a non-exclusive, worldwide, royalty-free
		507	patent license under the contributor's essential patent claims, to
		508	make, use, sell, offer for sale, import and otherwise run, modify and
		509	propagate the contents of its contributor version.</p>
		510
		511	<p>In the following three paragraphs, a “patent license” is any express
		512	agreement or commitment, however denominated, not to enforce a patent
		513	(such as an express permission to practice a patent or covenant not to
		514	sue for patent infringement). To “grant” such a patent license to a
		515	party means to make such an agreement or commitment not to enforce a
		516	patent against the party.</p>
		517
		518	<p>If you convey a covered work, knowingly relying on a patent license,
		519	and the Corresponding Source of the work is not available for anyone
		520	to copy, free of charge and under the terms of this License, through a
		521	publicly available network server or other readily accessible means,
		522	then you must either (1) cause the Corresponding Source to be so
		523	available, or (2) arrange to deprive yourself of the benefit of the
		524	patent license for this particular work, or (3) arrange, in a manner
		525	consistent with the requirements of this License, to extend the patent
		526	license to downstream recipients. “Knowingly relying” means you have
		527	actual knowledge that, but for the patent license, your conveying the
		528	covered work in a country, or your recipient's use of the covered work
		529	in a country, would infringe one or more identifiable patents in that
		530	country that you have reason to believe are valid.</p>
		531
		532	<p>If, pursuant to or in connection with a single transaction or
		533	arrangement, you convey, or propagate by procuring conveyance of, a
		534	covered work, and grant a patent license to some of the parties
		535	receiving the covered work authorizing them to use, propagate, modify
		536	or convey a specific copy of the covered work, then the patent license
		537	you grant is automatically extended to all recipients of the covered
		538	work and works based on it.</p>
		539
		540	<p>A patent license is “discriminatory” if it does not include within
		541	the scope of its coverage, prohibits the exercise of, or is
		542	conditioned on the non-exercise of one or more of the rights that are
		543	specifically granted under this License. You may not convey a covered
		544	work if you are a party to an arrangement with a third party that is
		545	in the business of distributing software, under which you make payment
		546	to the third party based on the extent of your activity of conveying
		547	the work, and under which the third party grants, to any of the
		548	parties who would receive the covered work from you, a discriminatory
		549	patent license (a) in connection with copies of the covered work
		550	conveyed by you (or copies made from those copies), or (b) primarily
		551	for and in connection with specific products or compilations that
		552	contain the covered work, unless you entered into that arrangement,
		553	or that patent license was granted, prior to 28 March 2007.</p>
		554
		555	<p>Nothing in this License shall be construed as excluding or limiting
		556	any implied license or other defenses to infringement that may
		557	otherwise be available to you under applicable patent law.</p>
		558
		559	<h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
		560
		561	<p>If conditions are imposed on you (whether by court order, agreement or
		562	otherwise) that contradict the conditions of this License, they do not
		563	excuse you from the conditions of this License. If you cannot convey a
		564	covered work so as to satisfy simultaneously your obligations under this
		565	License and any other pertinent obligations, then as a consequence you may
		566	not convey it at all. For example, if you agree to terms that obligate you
		567	to collect a royalty for further conveying from those to whom you convey
		568	the Program, the only way you could satisfy both those terms and this
		569	License would be to refrain entirely from conveying the Program.</p>
		570
		571	<h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
		572
		573	<p>Notwithstanding any other provision of this License, you have
		574	permission to link or combine any covered work with a work licensed
		575	under version 3 of the GNU Affero General Public License into a single
		576	combined work, and to convey the resulting work. The terms of this
		577	License will continue to apply to the part which is the covered work,
		578	but the special requirements of the GNU Affero General Public License,
		579	section 13, concerning interaction through a network will apply to the
		580	combination as such.</p>
		581
		582	<h4><a name="section14"></a>14. Revised Versions of this License.</h4>
		583
		584	<p>The Free Software Foundation may publish revised and/or new versions of
		585	the GNU General Public License from time to time. Such new versions will
		586	be similar in spirit to the present version, but may differ in detail to
		587	address new problems or concerns.</p>
		588
		589	<p>Each version is given a distinguishing version number. If the
		590	Program specifies that a certain numbered version of the GNU General
		591	Public License “or any later version” applies to it, you have the
		592	option of following the terms and conditions either of that numbered
		593	version or of any later version published by the Free Software
		594	Foundation. If the Program does not specify a version number of the
		595	GNU General Public License, you may choose any version ever published
		596	by the Free Software Foundation.</p>
		597
		598	<p>If the Program specifies that a proxy can decide which future
		599	versions of the GNU General Public License can be used, that proxy's
		600	public statement of acceptance of a version permanently authorizes you
		601	to choose that version for the Program.</p>
		602
		603	<p>Later license versions may give you additional or different
		604	permissions. However, no additional obligations are imposed on any
		605	author or copyright holder as a result of your choosing to follow a
		606	later version.</p>
		607
		608	<h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
		609
		610	<p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
		611	APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
		612	HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY
		613	OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
		614	THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
		615	PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
		616	IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
		617	ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
		618
		619	<h4><a name="section16"></a>16. Limitation of Liability.</h4>
		620
		621	<p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
		622	WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
		623	THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
		624	GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
		625	USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
		626	DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
		627	PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
		628	EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
		629	SUCH DAMAGES.</p>
		630
		631	<h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
		632
		633	<p>If the disclaimer of warranty and limitation of liability provided
		634	above cannot be given local legal effect according to their terms,
		635	reviewing courts shall apply local law that most closely approximates
		636	an absolute waiver of all civil liability in connection with the
		637	Program, unless a warranty or assumption of liability accompanies a
		638	copy of the Program in return for a fee.</p>
		639
		640	<p>END OF TERMS AND CONDITIONS</p>
		641
		642	<h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
		643
		644	<p>If you develop a new program, and you want it to be of the greatest
		645	possible use to the public, the best way to achieve this is to make it
		646	free software which everyone can redistribute and change under these terms.</p>
		647
		648	<p>To do so, attach the following notices to the program. It is safest
		649	to attach them to the start of each source file to most effectively
		650	state the exclusion of warranty; and each file should have at least
		651	the “copyright” line and a pointer to where the full notice is found.</p>
		652
		653	<pre> <one line to give the program's name and a brief idea of what it does.>
		654	Copyright (C) <year> <name of author>

		659	(at your option) any later version.
		660
		661	This program is distributed in the hope that it will be useful,
		662	but WITHOUT ANY WARRANTY; without even the implied warranty of

		666	You should have received a copy of the GNU General Public License
		667	along with this program. If not, see <https://www.gnu.org/licenses/>.

		669
		670	<p>Also add information on how to contact you by electronic and paper mail.</p>
		671
		672	<p>If the program does terminal interaction, make it output a short
		673	notice like this when it starts in an interactive mode:</p>
		674
		675	<pre> <program> Copyright (C) <year> <name of author>
		676	This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
		677	This is free software, and you are welcome to redistribute it
		678	under certain conditions; type `show c' for details.
		679	</pre>
		680
		681	<p>The hypothetical commands `show w' and `show c' should show the appropriate
		682	parts of the General Public License. Of course, your program's commands
		683	might be different; for a GUI interface, you would use an “about box”.</p>
		684
		685	<p>You should also get your employer (if you work as a programmer) or school,
		686	if any, to sign a “copyright disclaimer” for the program, if necessary.

		690	<p>The GNU General Public License does not permit incorporating your program
		691	into proprietary programs. If your program is a subroutine library, you
		692	may consider it more useful to permit linking proprietary applications with
		693	the library. If this is what you want to do, use the GNU Lesser General
		694	Public License instead of this License. But first, please read
