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