  4 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
  5 Everyone is permitted to copy and distribute verbatim copies
  6 of this license document, but changing it is not allowed.

  9  This version of the GNU Lesser General Public License incorporates
 10the terms and conditions of version 3 of the GNU General Public
 11License, supplemented by the additional permissions listed below.
 12
 13  0. Additional Definitions.
 14
 15  As used herein, "this License" refers to version 3 of the GNU Lesser
 16General Public License, and the "GNU GPL" refers to version 3 of the GNU
 17General Public License.
 18
 19  "The Library" refers to a covered work governed by this License,
 20other than an Application or a Combined Work as defined below.
 21
 22  An "Application" is any work that makes use of an interface provided
 23by the Library, but which is not otherwise based on the Library.
 24Defining a subclass of a class defined by the Library is deemed a mode
 25of using an interface provided by the Library.
 26
 27  A "Combined Work" is a work produced by combining or linking an
 28Application with the Library.  The particular version of the Library
 29with which the Combined Work was made is also called the "Linked
 30Version".
 31
 32  The "Minimal Corresponding Source" for a Combined Work means the
 33Corresponding Source for the Combined Work, excluding any source code
 34for portions of the Combined Work that, considered in isolation, are
 35based on the Application, and not on the Linked Version.
 36
 37  The "Corresponding Application Code" for a Combined Work means the
 38object code and/or source code for the Application, including any data
 39and utility programs needed for reproducing the Combined Work from the
 40Application, but excluding the System Libraries of the Combined Work.
 41
 42  1. Exception to Section 3 of the GNU GPL.
 43
 44  You may convey a covered work under sections 3 and 4 of this License
 45without being bound by section 3 of the GNU GPL.
 46
 47  2. Conveying Modified Versions.
 48
 49  If you modify a copy of the Library, and, in your modifications, a
 50facility refers to a function or data to be supplied by an Application
 51that uses the facility (other than as an argument passed when the
 52facility is invoked), then you may convey a copy of the modified
 53version:
 54
 55   a) under this License, provided that you make a good faith effort to
 56   ensure that, in the event an Application does not supply the
 57   function or data, the facility still operates, and performs
 58   whatever part of its purpose remains meaningful, or
 59
 60   b) under the GNU GPL, with none of the additional permissions of
 61   this License applicable to that copy.
 62
 63  3. Object Code Incorporating Material from Library Header Files.
 64
 65  The object code form of an Application may incorporate material from
 66a header file that is part of the Library.  You may convey such object
 67code under terms of your choice, provided that, if the incorporated
 68material is not limited to numerical parameters, data structure
 69layouts and accessors, or small macros, inline functions and templates
 70(ten or fewer lines in length), you do both of the following:
 71
 72   a) Give prominent notice with each copy of the object code that the
 73   Library is used in it and that the Library and its use are
 74   covered by this License.
 75
 76   b) Accompany the object code with a copy of the GNU GPL and this license
 77   document.
 78
 79  4. Combined Works.
 80
 81  You may convey a Combined Work under terms of your choice that,
 82taken together, effectively do not restrict modification of the
 83portions of the Library contained in the Combined Work and reverse
 84engineering for debugging such modifications, if you also do each of
 85the following:
 86
 87   a) Give prominent notice with each copy of the Combined Work that
 88   the Library is used in it and that the Library and its use are
 89   covered by this License.
 90
 91   b) Accompany the Combined Work with a copy of the GNU GPL and this license
 92   document.
 93
 94   c) For a Combined Work that displays copyright notices during
 95   execution, include the copyright notice for the Library among
 96   these notices, as well as a reference directing the user to the
 97   copies of the GNU GPL and this license document.
 98
 99   d) Do one of the following:
100
101       0) Convey the Minimal Corresponding Source under the terms of this
102       License, and the Corresponding Application Code in a form
103       suitable for, and under terms that permit, the user to
104       recombine or relink the Application with a modified version of
105       the Linked Version to produce a modified Combined Work, in the
106       manner specified by section 6 of the GNU GPL for conveying
107       Corresponding Source.
108
109       1) Use a suitable shared library mechanism for linking with the
110       Library.  A suitable mechanism is one that (a) uses at run time
111       a copy of the Library already present on the user's computer
112       system, and (b) will operate properly with a modified version
113       of the Library that is interface-compatible with the Linked
114       Version.
115
116   e) Provide Installation Information, but only if you would otherwise
117   be required to provide such information under section 6 of the
118   GNU GPL, and only to the extent that such information is
119   necessary to install and execute a modified version of the
120   Combined Work produced by recombining or relinking the
121   Application with a modified version of the Linked Version. (If
122   you use option 4d0, the Installation Information must accompany
123   the Minimal Corresponding Source and Corresponding Application
124   Code. If you use option 4d1, you must provide the Installation
125   Information in the manner specified by section 6 of the GNU GPL
126   for conveying Corresponding Source.)
127
128  5. Combined Libraries.
129
130  You may place library facilities that are a work based on the
131Library side by side in a single library together with other library
132facilities that are not Applications and are not covered by this
133License, and convey such a combined library under terms of your
134choice, if you do both of the following:
135
136   a) Accompany the combined library with a copy of the same work based
137   on the Library, uncombined with any other library facilities,
138   conveyed under the terms of this License.
139
140   b) Give prominent notice with the combined library that part of it
141   is a work based on the Library, and explaining where to find the
142   accompanying uncombined form of the same work.
143
144  6. Revised Versions of the GNU Lesser General Public License.
145
146  The Free Software Foundation may publish revised and/or new versions
147of the GNU Lesser General Public License from time to time. Such new
148versions will be similar in spirit to the present version, but may
149differ in detail to address new problems or concerns.
150
151  Each version is given a distinguishing version number. If the
152Library as you received it specifies that a certain numbered version
153of the GNU Lesser General Public License "or any later version"
154applies to it, you have the option of following the terms and
155conditions either of that published version or of any later version
156published by the Free Software Foundation. If the Library as you
157received it does not specify a version number of the GNU Lesser
158General Public License, you may choose any version of the GNU Lesser
159General Public License ever published by the Free Software Foundation.
160
161  If the Library as you received it specifies that a proxy can decide
162whether future versions of the GNU Lesser General Public License shall
163apply, that proxy's public statement of acceptance of any version is
164permanent authorization for you to choose that version for the
165Library.
166
167
168
169                    GNU GENERAL PUBLIC LICENSE
170                       Version 3, 29 June 2007
171
172 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
173 Everyone is permitted to copy and distribute verbatim copies
174 of this license document, but changing it is not allowed.
175
176                            Preamble
177
178  The GNU General Public License is a free, copyleft license for
179software and other kinds of works.
180
181  The licenses for most software and other practical works are designed
182to take away your freedom to share and change the works.  By contrast,
183the GNU General Public License is intended to guarantee your freedom to
184share and change all versions of a program--to make sure it remains free
185software for all its users.  We, the Free Software Foundation, use the
186GNU General Public License for most of our software; it applies also to
187any other work released this way by its authors.  You can apply it to
188your programs, too.
189
190  When we speak of free software, we are referring to freedom, not
191price.  Our General Public Licenses are designed to make sure that you
192have the freedom to distribute copies of free software (and charge for
193them if you wish), that you receive source code or can get it if you
194want it, that you can change the software or use pieces of it in new
195free programs, and that you know you can do these things.
196
197  To protect your rights, we need to prevent others from denying you
198these rights or asking you to surrender the rights.  Therefore, you have
199certain responsibilities if you distribute copies of the software, or if
200you modify it: responsibilities to respect the freedom of others.
201
202  For example, if you distribute copies of such a program, whether
203gratis or for a fee, you must pass on to the recipients the same
204freedoms that you received.  You must make sure that they, too, receive
205or can get the source code.  And you must show them these terms so they
206know their rights.
207
208  Developers that use the GNU GPL protect your rights with two steps:
209(1) assert copyright on the software, and (2) offer you this License
210giving you legal permission to copy, distribute and/or modify it.
211
212  For the developers' and authors' protection, the GPL clearly explains
213that there is no warranty for this free software.  For both users' and
214authors' sake, the GPL requires that modified versions be marked as
215changed, so that their problems will not be attributed erroneously to
216authors of previous versions.
217
218  Some devices are designed to deny users access to install or run
219modified versions of the software inside them, although the manufacturer
220can do so.  This is fundamentally incompatible with the aim of
221protecting users' freedom to change the software.  The systematic
222pattern of such abuse occurs in the area of products for individuals to
223use, which is precisely where it is most unacceptable.  Therefore, we
224have designed this version of the GPL to prohibit the practice for those
225products.  If such problems arise substantially in other domains, we
226stand ready to extend this provision to those domains in future versions
227of the GPL, as needed to protect the freedom of users.
228
229  Finally, every program is threatened constantly by software patents.
230States should not allow patents to restrict development and use of
231software on general-purpose computers, but in those that do, we wish to
232avoid the special danger that patents applied to a free program could
233make it effectively proprietary.  To prevent this, the GPL assures that
234patents cannot be used to render the program non-free.
235
236  The precise terms and conditions for copying, distribution and
237modification follow.
238
239                       TERMS AND CONDITIONS
240
241  0. Definitions.
242
243  "This License" refers to version 3 of the GNU General Public License.
244
245  "Copyright" also means copyright-like laws that apply to other kinds of
246works, such as semiconductor masks.
247
248  "The Program" refers to any copyrightable work licensed under this
249License.  Each licensee is addressed as "you".  "Licensees" and
250"recipients" may be individuals or organizations.
251
252  To "modify" a work means to copy from or adapt all or part of the work
253in a fashion requiring copyright permission, other than the making of an
254exact copy.  The resulting work is called a "modified version" of the
255earlier work or a work "based on" the earlier work.
256
257  A "covered work" means either the unmodified Program or a work based
258on the Program.
259
260  To "propagate" a work means to do anything with it that, without
261permission, would make you directly or secondarily liable for
262infringement under applicable copyright law, except executing it on a
263computer or modifying a private copy.  Propagation includes copying,
264distribution (with or without modification), making available to the
265public, and in some countries other activities as well.
266
267  To "convey" a work means any kind of propagation that enables other
268parties to make or receive copies.  Mere interaction with a user through
269a computer network, with no transfer of a copy, is not conveying.
270
271  An interactive user interface displays "Appropriate Legal Notices"
272to the extent that it includes a convenient and prominently visible
273feature that (1) displays an appropriate copyright notice, and (2)
274tells the user that there is no warranty for the work (except to the
275extent that warranties are provided), that licensees may convey the
276work under this License, and how to view a copy of this License.  If
277the interface presents a list of user commands or options, such as a
278menu, a prominent item in the list meets this criterion.
279
280  1. Source Code.
281
282  The "source code" for a work means the preferred form of the work
283for making modifications to it.  "Object code" means any non-source
284form of a work.
285
286  A "Standard Interface" means an interface that either is an official
287standard defined by a recognized standards body, or, in the case of
288interfaces specified for a particular programming language, one that
289is widely used among developers working in that language.
290
291  The "System Libraries" of an executable work include anything, other
292than the work as a whole, that (a) is included in the normal form of
293packaging a Major Component, but which is not part of that Major
294Component, and (b) serves only to enable use of the work with that
295Major Component, or to implement a Standard Interface for which an
296implementation is available to the public in source code form.  A
297"Major Component", in this context, means a major essential component
298(kernel, window system, and so on) of the specific operating system
299(if any) on which the executable work runs, or a compiler used to
300produce the work, or an object code interpreter used to run it.
301
302  The "Corresponding Source" for a work in object code form means all
303the source code needed to generate, install, and (for an executable
304work) run the object code and to modify the work, including scripts to
305control those activities.  However, it does not include the work's
306System Libraries, or general-purpose tools or generally available free
307programs which are used unmodified in performing those activities but
308which are not part of the work.  For example, Corresponding Source
309includes interface definition files associated with source files for
310the work, and the source code for shared libraries and dynamically
311linked subprograms that the work is specifically designed to require,
312such as by intimate data communication or control flow between those
313subprograms and other parts of the work.
314
315  The Corresponding Source need not include anything that users
316can regenerate automatically from other parts of the Corresponding
317Source.
318
319  The Corresponding Source for a work in source code form is that
320same work.
321
322  2. Basic Permissions.
323
324  All rights granted under this License are granted for the term of
325copyright on the Program, and are irrevocable provided the stated
326conditions are met.  This License explicitly affirms your unlimited
327permission to run the unmodified Program.  The output from running a
328covered work is covered by this License only if the output, given its
329content, constitutes a covered work.  This License acknowledges your
330rights of fair use or other equivalent, as provided by copyright law.
331
332  You may make, run and propagate covered works that you do not
333convey, without conditions so long as your license otherwise remains
334in force.  You may convey covered works to others for the sole purpose
335of having them make modifications exclusively for you, or provide you
336with facilities for running those works, provided that you comply with
337the terms of this License in conveying all material for which you do
338not control copyright.  Those thus making or running the covered works
339for you must do so exclusively on your behalf, under your direction
340and control, on terms that prohibit them from making any copies of
341your copyrighted material outside their relationship with you.
342
343  Conveying under any other circumstances is permitted solely under
344the conditions stated below.  Sublicensing is not allowed; section 10
345makes it unnecessary.
346
347  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
348
349  No covered work shall be deemed part of an effective technological
350measure under any applicable law fulfilling obligations under article
35111 of the WIPO copyright treaty adopted on 20 December 1996, or
352similar laws prohibiting or restricting circumvention of such
353measures.
354
355  When you convey a covered work, you waive any legal power to forbid
356circumvention of technological measures to the extent such circumvention
357is effected by exercising rights under this License with respect to
358the covered work, and you disclaim any intention to limit operation or
359modification of the work as a means of enforcing, against the work's
360users, your or third parties' legal rights to forbid circumvention of
361technological measures.
362
363  4. Conveying Verbatim Copies.
364
365  You may convey verbatim copies of the Program's source code as you
366receive it, in any medium, provided that you conspicuously and
367appropriately publish on each copy an appropriate copyright notice;
368keep intact all notices stating that this License and any
369non-permissive terms added in accord with section 7 apply to the code;
370keep intact all notices of the absence of any warranty; and give all
371recipients a copy of this License along with the Program.
372
373  You may charge any price or no price for each copy that you convey,
374and you may offer support or warranty protection for a fee.
375
376  5. Conveying Modified Source Versions.
377
378  You may convey a work based on the Program, or the modifications to
379produce it from the Program, in the form of source code under the
380terms of section 4, provided that you also meet all of these conditions:
381
382    a) The work must carry prominent notices stating that you modified
383    it, and giving a relevant date.
384
385    b) The work must carry prominent notices stating that it is
386    released under this License and any conditions added under section
387    7.  This requirement modifies the requirement in section 4 to
388    "keep intact all notices".
389
390    c) You must license the entire work, as a whole, under this
391    License to anyone who comes into possession of a copy.  This
392    License will therefore apply, along with any applicable section 7
393    additional terms, to the whole of the work, and all its parts,
394    regardless of how they are packaged.  This License gives no
395    permission to license the work in any other way, but it does not
396    invalidate such permission if you have separately received it.
397
398    d) If the work has interactive user interfaces, each must display
399    Appropriate Legal Notices; however, if the Program has interactive
400    interfaces that do not display Appropriate Legal Notices, your
401    work need not make them do so.
402
403  A compilation of a covered work with other separate and independent
404works, which are not by their nature extensions of the covered work,
405and which are not combined with it such as to form a larger program,
406in or on a volume of a storage or distribution medium, is called an
407"aggregate" if the compilation and its resulting copyright are not
408used to limit the access or legal rights of the compilation's users
409beyond what the individual works permit.  Inclusion of a covered work
410in an aggregate does not cause this License to apply to the other
411parts of the aggregate.
412
413  6. Conveying Non-Source Forms.
414
415  You may convey a covered work in object code form under the terms
416of sections 4 and 5, provided that you also convey the
417machine-readable Corresponding Source under the terms of this License,
418in one of these ways:
419
420    a) Convey the object code in, or embodied in, a physical product
421    (including a physical distribution medium), accompanied by the
422    Corresponding Source fixed on a durable physical medium
423    customarily used for software interchange.
424
425    b) Convey the object code in, or embodied in, a physical product
426    (including a physical distribution medium), accompanied by a
427    written offer, valid for at least three years and valid for as
428    long as you offer spare parts or customer support for that product
429    model, to give anyone who possesses the object code either (1) a
430    copy of the Corresponding Source for all the software in the
431    product that is covered by this License, on a durable physical
432    medium customarily used for software interchange, for a price no
433    more than your reasonable cost of physically performing this
434    conveying of source, or (2) access to copy the
435    Corresponding Source from a network server at no charge.
436
437    c) Convey individual copies of the object code with a copy of the
438    written offer to provide the Corresponding Source.  This
439    alternative is allowed only occasionally and noncommercially, and
440    only if you received the object code with such an offer, in accord
441    with subsection 6b.
442
443    d) Convey the object code by offering access from a designated
444    place (gratis or for a charge), and offer equivalent access to the
445    Corresponding Source in the same way through the same place at no
446    further charge.  You need not require recipients to copy the
447    Corresponding Source along with the object code.  If the place to
448    copy the object code is a network server, the Corresponding Source
449    may be on a different server (operated by you or a third party)
450    that supports equivalent copying facilities, provided you maintain
451    clear directions next to the object code saying where to find the
452    Corresponding Source.  Regardless of what server hosts the
453    Corresponding Source, you remain obligated to ensure that it is
454    available for as long as needed to satisfy these requirements.
455
456    e) Convey the object code using peer-to-peer transmission, provided
457    you inform other peers where the object code and Corresponding
458    Source of the work are being offered to the general public at no
459    charge under subsection 6d.
460
461  A separable portion of the object code, whose source code is excluded
462from the Corresponding Source as a System Library, need not be
463included in conveying the object code work.
464
465  A "User Product" is either (1) a "consumer product", which means any
466tangible personal property which is normally used for personal, family,
467or household purposes, or (2) anything designed or sold for incorporation
468into a dwelling.  In determining whether a product is a consumer product,
469doubtful cases shall be resolved in favor of coverage.  For a particular
470product received by a particular user, "normally used" refers to a
471typical or common use of that class of product, regardless of the status
472of the particular user or of the way in which the particular user
473actually uses, or expects or is expected to use, the product.  A product
474is a consumer product regardless of whether the product has substantial
475commercial, industrial or non-consumer uses, unless such uses represent
476the only significant mode of use of the product.
477
478  "Installation Information" for a User Product means any methods,
479procedures, authorization keys, or other information required to install
480and execute modified versions of a covered work in that User Product from
481a modified version of its Corresponding Source.  The information must
482suffice to ensure that the continued functioning of the modified object
483code is in no case prevented or interfered with solely because
484modification has been made.
485
486  If you convey an object code work under this section in, or with, or
487specifically for use in, a User Product, and the conveying occurs as
488part of a transaction in which the right of possession and use of the
489User Product is transferred to the recipient in perpetuity or for a
490fixed term (regardless of how the transaction is characterized), the
491Corresponding Source conveyed under this section must be accompanied
492by the Installation Information.  But this requirement does not apply
493if neither you nor any third party retains the ability to install
494modified object code on the User Product (for example, the work has
495been installed in ROM).
496
497  The requirement to provide Installation Information does not include a
498requirement to continue to provide support service, warranty, or updates
499for a work that has been modified or installed by the recipient, or for
500the User Product in which it has been modified or installed.  Access to a
501network may be denied when the modification itself materially and
502adversely affects the operation of the network or violates the rules and
503protocols for communication across the network.
504
505  Corresponding Source conveyed, and Installation Information provided,
506in accord with this section must be in a format that is publicly
507documented (and with an implementation available to the public in
508source code form), and must require no special password or key for
509unpacking, reading or copying.
510
511  7. Additional Terms.
512
513  "Additional permissions" are terms that supplement the terms of this
514License by making exceptions from one or more of its conditions.
515Additional permissions that are applicable to the entire Program shall
516be treated as though they were included in this License, to the extent
517that they are valid under applicable law.  If additional permissions
518apply only to part of the Program, that part may be used separately
519under those permissions, but the entire Program remains governed by
520this License without regard to the additional permissions.
521
522  When you convey a copy of a covered work, you may at your option
523remove any additional permissions from that copy, or from any part of
524it.  (Additional permissions may be written to require their own
525removal in certain cases when you modify the work.)  You may place
526additional permissions on material, added by you to a covered work,
527for which you have or can give appropriate copyright permission.
528
529  Notwithstanding any other provision of this License, for material you
530add to a covered work, you may (if authorized by the copyright holders of
531that material) supplement the terms of this License with terms:
532
533    a) Disclaiming warranty or limiting liability differently from the
534    terms of sections 15 and 16 of this License; or
535
536    b) Requiring preservation of specified reasonable legal notices or
537    author attributions in that material or in the Appropriate Legal
538    Notices displayed by works containing it; or
539
540    c) Prohibiting misrepresentation of the origin of that material, or
541    requiring that modified versions of such material be marked in
542    reasonable ways as different from the original version; or
543
544    d) Limiting the use for publicity purposes of names of licensors or
545    authors of the material; or
546
547    e) Declining to grant rights under trademark law for use of some
548    trade names, trademarks, or service marks; or
549
550    f) Requiring indemnification of licensors and authors of that
551    material by anyone who conveys the material (or modified versions of
552    it) with contractual assumptions of liability to the recipient, for
553    any liability that these contractual assumptions directly impose on
554    those licensors and authors.
555
556  All other non-permissive additional terms are considered "further
557restrictions" within the meaning of section 10.  If the Program as you
558received it, or any part of it, contains a notice stating that it is
559governed by this License along with a term that is a further
560restriction, you may remove that term.  If a license document contains
561a further restriction but permits relicensing or conveying under this
562License, you may add to a covered work material governed by the terms
563of that license document, provided that the further restriction does
564not survive such relicensing or conveying.
565
566  If you add terms to a covered work in accord with this section, you
567must place, in the relevant source files, a statement of the
568additional terms that apply to those files, or a notice indicating
569where to find the applicable terms.
570
571  Additional terms, permissive or non-permissive, may be stated in the
572form of a separately written license, or stated as exceptions;
573the above requirements apply either way.
574
575  8. Termination.
576
577  You may not propagate or modify a covered work except as expressly
578provided under this License.  Any attempt otherwise to propagate or
579modify it is void, and will automatically terminate your rights under
580this License (including any patent licenses granted under the third
581paragraph of section 11).
582
583  However, if you cease all violation of this License, then your
584license from a particular copyright holder is reinstated (a)
585provisionally, unless and until the copyright holder explicitly and
586finally terminates your license, and (b) permanently, if the copyright
587holder fails to notify you of the violation by some reasonable means
588prior to 60 days after the cessation.
589
590  Moreover, your license from a particular copyright holder is
591reinstated permanently if the copyright holder notifies you of the
592violation by some reasonable means, this is the first time you have
593received notice of violation of this License (for any work) from that
594copyright holder, and you cure the violation prior to 30 days after
595your receipt of the notice.
596
597  Termination of your rights under this section does not terminate the
598licenses of parties who have received copies or rights from you under
599this License.  If your rights have been terminated and not permanently
600reinstated, you do not qualify to receive new licenses for the same
601material under section 10.
602
603  9. Acceptance Not Required for Having Copies.
604
605  You are not required to accept this License in order to receive or
606run a copy of the Program.  Ancillary propagation of a covered work
607occurring solely as a consequence of using peer-to-peer transmission
608to receive a copy likewise does not require acceptance.  However,
609nothing other than this License grants you permission to propagate or
610modify any covered work.  These actions infringe copyright if you do
611not accept this License.  Therefore, by modifying or propagating a
612covered work, you indicate your acceptance of this License to do so.
613
614  10. Automatic Licensing of Downstream Recipients.
615
616  Each time you convey a covered work, the recipient automatically
617receives a license from the original licensors, to run, modify and
618propagate that work, subject to this License.  You are not responsible
619for enforcing compliance by third parties with this License.
620
621  An "entity transaction" is a transaction transferring control of an
622organization, or substantially all assets of one, or subdividing an
623organization, or merging organizations.  If propagation of a covered
624work results from an entity transaction, each party to that
625transaction who receives a copy of the work also receives whatever
626licenses to the work the party's predecessor in interest had or could
627give under the previous paragraph, plus a right to possession of the
628Corresponding Source of the work from the predecessor in interest, if
629the predecessor has it or can get it with reasonable efforts.
630
631  You may not impose any further restrictions on the exercise of the
632rights granted or affirmed under this License.  For example, you may
633not impose a license fee, royalty, or other charge for exercise of
634rights granted under this License, and you may not initiate litigation
635(including a cross-claim or counterclaim in a lawsuit) alleging that
636any patent claim is infringed by making, using, selling, offering for
637sale, or importing the Program or any portion of it.
638
639  11. Patents.
640
641  A "contributor" is a copyright holder who authorizes use under this
642License of the Program or a work on which the Program is based.  The
643work thus licensed is called the contributor's "contributor version".
644
645  A contributor's "essential patent claims" are all patent claims
646owned or controlled by the contributor, whether already acquired or
647hereafter acquired, that would be infringed by some manner, permitted
648by this License, of making, using, or selling its contributor version,
649but do not include claims that would be infringed only as a
650consequence of further modification of the contributor version.  For
651purposes of this definition, "control" includes the right to grant
652patent sublicenses in a manner consistent with the requirements of
653this License.
654
655  Each contributor grants you a non-exclusive, worldwide, royalty-free
656patent license under the contributor's essential patent claims, to
657make, use, sell, offer for sale, import and otherwise run, modify and
658propagate the contents of its contributor version.
659
660  In the following three paragraphs, a "patent license" is any express
661agreement or commitment, however denominated, not to enforce a patent
662(such as an express permission to practice a patent or covenant not to
663sue for patent infringement).  To "grant" such a patent license to a
664party means to make such an agreement or commitment not to enforce a
665patent against the party.
666
667  If you convey a covered work, knowingly relying on a patent license,
668and the Corresponding Source of the work is not available for anyone
669to copy, free of charge and under the terms of this License, through a
670publicly available network server or other readily accessible means,
671then you must either (1) cause the Corresponding Source to be so
672available, or (2) arrange to deprive yourself of the benefit of the
673patent license for this particular work, or (3) arrange, in a manner
674consistent with the requirements of this License, to extend the patent
675license to downstream recipients.  "Knowingly relying" means you have
676actual knowledge that, but for the patent license, your conveying the
677covered work in a country, or your recipient's use of the covered work
678in a country, would infringe one or more identifiable patents in that
679country that you have reason to believe are valid.
680
681  If, pursuant to or in connection with a single transaction or
682arrangement, you convey, or propagate by procuring conveyance of, a
683covered work, and grant a patent license to some of the parties
684receiving the covered work authorizing them to use, propagate, modify
685or convey a specific copy of the covered work, then the patent license
686you grant is automatically extended to all recipients of the covered
687work and works based on it.
688
689  A patent license is "discriminatory" if it does not include within
690the scope of its coverage, prohibits the exercise of, or is
691conditioned on the non-exercise of one or more of the rights that are
692specifically granted under this License.  You may not convey a covered
693work if you are a party to an arrangement with a third party that is
694in the business of distributing software, under which you make payment
695to the third party based on the extent of your activity of conveying
696the work, and under which the third party grants, to any of the
697parties who would receive the covered work from you, a discriminatory
698patent license (a) in connection with copies of the covered work
699conveyed by you (or copies made from those copies), or (b) primarily
700for and in connection with specific products or compilations that
701contain the covered work, unless you entered into that arrangement,
702or that patent license was granted, prior to 28 March 2007.
703
704  Nothing in this License shall be construed as excluding or limiting
705any implied license or other defenses to infringement that may
706otherwise be available to you under applicable patent law.
707
708  12. No Surrender of Others' Freedom.
709
710  If conditions are imposed on you (whether by court order, agreement or
711otherwise) that contradict the conditions of this License, they do not
712excuse you from the conditions of this License.  If you cannot convey a
713covered work so as to satisfy simultaneously your obligations under this
714License and any other pertinent obligations, then as a consequence you may
715not convey it at all.  For example, if you agree to terms that obligate you
716to collect a royalty for further conveying from those to whom you convey
717the Program, the only way you could satisfy both those terms and this
718License would be to refrain entirely from conveying the Program.
719
720  13. Use with the GNU Affero General Public License.
721
722  Notwithstanding any other provision of this License, you have
723permission to link or combine any covered work with a work licensed
724under version 3 of the GNU Affero General Public License into a single
725combined work, and to convey the resulting work.  The terms of this
726License will continue to apply to the part which is the covered work,
727but the special requirements of the GNU Affero General Public License,
728section 13, concerning interaction through a network will apply to the
729combination as such.
730
731  14. Revised Versions of this License.
732
733  The Free Software Foundation may publish revised and/or new versions of
734the GNU General Public License from time to time.  Such new versions will
735be similar in spirit to the present version, but may differ in detail to
736address new problems or concerns.
737
738  Each version is given a distinguishing version number.  If the
739Program specifies that a certain numbered version of the GNU General
740Public License "or any later version" applies to it, you have the
741option of following the terms and conditions either of that numbered
742version or of any later version published by the Free Software
743Foundation.  If the Program does not specify a version number of the
744GNU General Public License, you may choose any version ever published
745by the Free Software Foundation.
746
747  If the Program specifies that a proxy can decide which future
748versions of the GNU General Public License can be used, that proxy's
749public statement of acceptance of a version permanently authorizes you
750to choose that version for the Program.
751
752  Later license versions may give you additional or different
753permissions.  However, no additional obligations are imposed on any
754author or copyright holder as a result of your choosing to follow a
755later version.
756
757  15. Disclaimer of Warranty.
758
759  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
760APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
761HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
762OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
763THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
764PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
765IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
766ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
767
768  16. Limitation of Liability.
769
770  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
771WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
772THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
773GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
774USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
775DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
776PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
777EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
778SUCH DAMAGES.
779
780  17. Interpretation of Sections 15 and 16.
781
782  If the disclaimer of warranty and limitation of liability provided
783above cannot be given local legal effect according to their terms,
784reviewing courts shall apply local law that most closely approximates
785an absolute waiver of all civil liability in connection with the
786Program, unless a warranty or assumption of liability accompanies a
787copy of the Program in return for a fee.
788
789                     END OF TERMS AND CONDITIONS
790
791            How to Apply These Terms to Your New Programs
792
793  If you develop a new program, and you want it to be of the greatest
794possible use to the public, the best way to achieve this is to make it
795free software which everyone can redistribute and change under these terms.
796
797  To do so, attach the following notices to the program.  It is safest
798to attach them to the start of each source file to most effectively
799state the exclusion of warranty; and each file should have at least
800the "copyright" line and a pointer to where the full notice is found.
801
802    <one line to give the program's name and a brief idea of what it does.>
803    Copyright (C) <year>  <name of author>
804
805    This program is free software: you can redistribute it and/or modify
806    it under the terms of the GNU General Public License as published by
807    the Free Software Foundation, either version 3 of the License, or
808    (at your option) any later version.
809
810    This program is distributed in the hope that it will be useful,
811    but WITHOUT ANY WARRANTY; without even the implied warranty of
812    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
813    GNU General Public License for more details.
814
815    You should have received a copy of the GNU General Public License
816    along with this program.  If not, see <https://www.gnu.org/licenses/>.
817
818Also add information on how to contact you by electronic and paper mail.
819
820  If the program does terminal interaction, make it output a short
821notice like this when it starts in an interactive mode:
822
823    <program>  Copyright (C) <year>  <name of author>
824    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
825    This is free software, and you are welcome to redistribute it
826    under certain conditions; type `show c' for details.
827
828The hypothetical commands `show w' and `show c' should show the appropriate
829parts of the General Public License.  Of course, your program's commands
830might be different; for a GUI interface, you would use an "about box".
831
832  You should also get your employer (if you work as a programmer) or school,
833if any, to sign a "copyright disclaimer" for the program, if necessary.
834For more information on this, and how to apply and follow the GNU GPL, see
835<https://www.gnu.org/licenses/>.
836
837  The GNU General Public License does not permit incorporating your program
838into proprietary programs.  If your program is a subroutine library, you
839may consider it more useful to permit linking proprietary applications with
840the library.  If this is what you want to do, use the GNU Lesser General
841Public License instead of this License.  But first, please read
842<https://www.gnu.org/licenses/why-not-lgpl.html>.
