xref: /aosp_15_r20/external/angle/third_party/glslang/src/LICENSE.txt (revision 8975f5c5ed3d1c378011245431ada316dfb6f244)
1Here, glslang proper means core GLSL parsing, HLSL parsing, and SPIR-V code
2generation. Glslang proper requires use of a number of licenses, one that covers
3preprocessing and others that covers non-preprocessing.
4
5Bison was removed long ago. You can build glslang from the source grammar,
6using tools of your choice, without using bison or any bison files.
7
8Other parts, outside of glslang proper, include:
9
10- gl_types.h, only needed for OpenGL-like reflection, and can be left out of
11  a parse and codegen project.  See it for its license.
12
13- update_glslang_sources.py, which is not part of the project proper and does
14  not need to be used.
15
16- the SPIR-V "remapper", which is optional, but has the same license as
17  glslang proper
18
19- Google tests and SPIR-V tools, and anything in the external subdirectory
20  are external and optional; see them for their respective licenses.

103   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
104
105   1. Definitions.
106
107      "License" shall mean the terms and conditions for use, reproduction,
108      and distribution as defined by Sections 1 through 9 of this document.
109
110      "Licensor" shall mean the copyright owner or entity authorized by
111      the copyright owner that is granting the License.
112
113      "Legal Entity" shall mean the union of the acting entity and all
114      other entities that control, are controlled by, or are under common
115      control with that entity. For the purposes of this definition,
116      "control" means (i) the power, direct or indirect, to cause the
117      direction or management of such entity, whether by contract or
118      otherwise, or (ii) ownership of fifty percent (50%) or more of the
119      outstanding shares, or (iii) beneficial ownership of such entity.
120
121      "You" (or "Your") shall mean an individual or Legal Entity
122      exercising permissions granted by this License.
123
124      "Source" form shall mean the preferred form for making modifications,
125      including but not limited to software source code, documentation
126      source, and configuration files.
127
128      "Object" form shall mean any form resulting from mechanical
129      transformation or translation of a Source form, including but
130      not limited to compiled object code, generated documentation,
131      and conversions to other media types.
132
133      "Work" shall mean the work of authorship, whether in Source or
134      Object form, made available under the License, as indicated by a
135      copyright notice that is included in or attached to the work
136      (an example is provided in the Appendix below).
137
138      "Derivative Works" shall mean any work, whether in Source or Object
139      form, that is based on (or derived from) the Work and for which the
140      editorial revisions, annotations, elaborations, or other modifications
141      represent, as a whole, an original work of authorship. For the purposes
142      of this License, Derivative Works shall not include works that remain
143      separable from, or merely link (or bind by name) to the interfaces of,
144      the Work and Derivative Works thereof.
145
146      "Contribution" shall mean any work of authorship, including
147      the original version of the Work and any modifications or additions
148      to that Work or Derivative Works thereof, that is intentionally
149      submitted to Licensor for inclusion in the Work by the copyright owner
150      or by an individual or Legal Entity authorized to submit on behalf of
151      the copyright owner. For the purposes of this definition, "submitted"
152      means any form of electronic, verbal, or written communication sent
153      to the Licensor or its representatives, including but not limited to
154      communication on electronic mailing lists, source code control systems,
155      and issue tracking systems that are managed by, or on behalf of, the
156      Licensor for the purpose of discussing and improving the Work, but
157      excluding communication that is conspicuously marked or otherwise
158      designated in writing by the copyright owner as "Not a Contribution."
159
160      "Contributor" shall mean Licensor and any individual or Legal Entity
161      on behalf of whom a Contribution has been received by Licensor and
162      subsequently incorporated within the Work.
163
164   2. Grant of Copyright License. Subject to the terms and conditions of
165      this License, each Contributor hereby grants to You a perpetual,
166      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
167      copyright license to reproduce, prepare Derivative Works of,
168      publicly display, publicly perform, sublicense, and distribute the
169      Work and such Derivative Works in Source or Object form.
170
171   3. Grant of Patent License. Subject to the terms and conditions of
172      this License, each Contributor hereby grants to You a perpetual,
173      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
174      (except as stated in this section) patent license to make, have made,
175      use, offer to sell, sell, import, and otherwise transfer the Work,
176      where such license applies only to those patent claims licensable
177      by such Contributor that are necessarily infringed by their
178      Contribution(s) alone or by combination of their Contribution(s)
179      with the Work to which such Contribution(s) was submitted. If You
180      institute patent litigation against any entity (including a
181      cross-claim or counterclaim in a lawsuit) alleging that the Work
182      or a Contribution incorporated within the Work constitutes direct
183      or contributory patent infringement, then any patent licenses
184      granted to You under this License for that Work shall terminate
185      as of the date such litigation is filed.
186
187   4. Redistribution. You may reproduce and distribute copies of the
188      Work or Derivative Works thereof in any medium, with or without
189      modifications, and in Source or Object form, provided that You
190      meet the following conditions:
191
192      (a) You must give any other recipients of the Work or
193          Derivative Works a copy of this License; and
194
195      (b) You must cause any modified files to carry prominent notices
196          stating that You changed the files; and
197
198      (c) You must retain, in the Source form of any Derivative Works
199          that You distribute, all copyright, patent, trademark, and
200          attribution notices from the Source form of the Work,
201          excluding those notices that do not pertain to any part of
202          the Derivative Works; and
203
204      (d) If the Work includes a "NOTICE" text file as part of its
205          distribution, then any Derivative Works that You distribute must
206          include a readable copy of the attribution notices contained
207          within such NOTICE file, excluding those notices that do not
208          pertain to any part of the Derivative Works, in at least one
209          of the following places: within a NOTICE text file distributed
210          as part of the Derivative Works; within the Source form or
211          documentation, if provided along with the Derivative Works; or,
212          within a display generated by the Derivative Works, if and
213          wherever such third-party notices normally appear. The contents
214          of the NOTICE file are for informational purposes only and
215          do not modify the License. You may add Your own attribution
216          notices within Derivative Works that You distribute, alongside
217          or as an addendum to the NOTICE text from the Work, provided
218          that such additional attribution notices cannot be construed
219          as modifying the License.
220
221      You may add Your own copyright statement to Your modifications and
222      may provide additional or different license terms and conditions
223      for use, reproduction, or distribution of Your modifications, or
224      for any such Derivative Works as a whole, provided Your use,
225      reproduction, and distribution of the Work otherwise complies with
226      the conditions stated in this License.
227
228   5. Submission of Contributions. Unless You explicitly state otherwise,
229      any Contribution intentionally submitted for inclusion in the Work
230      by You to the Licensor shall be under the terms and conditions of
231      this License, without any additional terms or conditions.
232      Notwithstanding the above, nothing herein shall supersede or modify
233      the terms of any separate license agreement you may have executed
234      with Licensor regarding such Contributions.
235
236   6. Trademarks. This License does not grant permission to use the trade
237      names, trademarks, service marks, or product names of the Licensor,
238      except as required for reasonable and customary use in describing the
239      origin of the Work and reproducing the content of the NOTICE file.
240
241   7. Disclaimer of Warranty. Unless required by applicable law or
242      agreed to in writing, Licensor provides the Work (and each
243      Contributor provides its Contributions) on an "AS IS" BASIS,
244      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
245      implied, including, without limitation, any warranties or conditions
246      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
247      PARTICULAR PURPOSE. You are solely responsible for determining the
248      appropriateness of using or redistributing the Work and assume any
249      risks associated with Your exercise of permissions under this License.
250
251   8. Limitation of Liability. In no event and under no legal theory,
252      whether in tort (including negligence), contract, or otherwise,
253      unless required by applicable law (such as deliberate and grossly
254      negligent acts) or agreed to in writing, shall any Contributor be
255      liable to You for damages, including any direct, indirect, special,
256      incidental, or consequential damages of any character arising as a
257      result of this License or out of the use or inability to use the
258      Work (including but not limited to damages for loss of goodwill,
259      work stoppage, computer failure or malfunction, or any and all
260      other commercial damages or losses), even if such Contributor
261      has been advised of the possibility of such damages.
262
263   9. Accepting Warranty or Additional Liability. While redistributing
264      the Work or Derivative Works thereof, You may choose to offer,
265      and charge a fee for, acceptance of support, warranty, indemnity,
266      or other liability obligations and/or rights consistent with this
267      License. However, in accepting such obligations, You may act only
268      on Your own behalf and on Your sole responsibility, not on behalf
269      of any other Contributor, and only if You agree to indemnify,
270      defend, and hold each Contributor harmless for any liability
271      incurred by, or claims asserted against, such Contributor by reason
272      of your accepting any such warranty or additional liability.

276   APPENDIX: How to apply the Apache License to your work.
277
278      To apply the Apache License to your work, attach the following
279      boilerplate notice, with the fields enclosed by brackets "[]"
280      replaced with your own identifying information. (Don't include
281      the brackets!)  The text should be enclosed in the appropriate
282      comment syntax for the file format. We also recommend that a
283      file or class name and description of purpose be included on the
284      same "printed page" as the copyright notice for easier
285      identification within third-party archives.

306                    GNU GENERAL PUBLIC LICENSE
307                       Version 3, 29 June 2007
308
309 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
310 Everyone is permitted to copy and distribute verbatim copies
311 of this license document, but changing it is not allowed.
312
313                            Preamble
314
315  The GNU General Public License is a free, copyleft license for
316software and other kinds of works.
317
318  The licenses for most software and other practical works are designed
319to take away your freedom to share and change the works.  By contrast,
320the GNU General Public License is intended to guarantee your freedom to
321share and change all versions of a program--to make sure it remains free
322software for all its users.  We, the Free Software Foundation, use the
323GNU General Public License for most of our software; it applies also to
324any other work released this way by its authors.  You can apply it to
325your programs, too.
326
327  When we speak of free software, we are referring to freedom, not
328price.  Our General Public Licenses are designed to make sure that you
329have the freedom to distribute copies of free software (and charge for
330them if you wish), that you receive source code or can get it if you
331want it, that you can change the software or use pieces of it in new
332free programs, and that you know you can do these things.
333
334  To protect your rights, we need to prevent others from denying you
335these rights or asking you to surrender the rights.  Therefore, you have
336certain responsibilities if you distribute copies of the software, or if
337you modify it: responsibilities to respect the freedom of others.
338
339  For example, if you distribute copies of such a program, whether
340gratis or for a fee, you must pass on to the recipients the same
341freedoms that you received.  You must make sure that they, too, receive
342or can get the source code.  And you must show them these terms so they
343know their rights.
344
345  Developers that use the GNU GPL protect your rights with two steps:
346(1) assert copyright on the software, and (2) offer you this License
347giving you legal permission to copy, distribute and/or modify it.
348
349  For the developers' and authors' protection, the GPL clearly explains
350that there is no warranty for this free software.  For both users' and
351authors' sake, the GPL requires that modified versions be marked as
352changed, so that their problems will not be attributed erroneously to
353authors of previous versions.
354
355  Some devices are designed to deny users access to install or run
356modified versions of the software inside them, although the manufacturer
357can do so.  This is fundamentally incompatible with the aim of
358protecting users' freedom to change the software.  The systematic
359pattern of such abuse occurs in the area of products for individuals to
360use, which is precisely where it is most unacceptable.  Therefore, we
361have designed this version of the GPL to prohibit the practice for those
362products.  If such problems arise substantially in other domains, we
363stand ready to extend this provision to those domains in future versions
364of the GPL, as needed to protect the freedom of users.
365
366  Finally, every program is threatened constantly by software patents.
367States should not allow patents to restrict development and use of
368software on general-purpose computers, but in those that do, we wish to
369avoid the special danger that patents applied to a free program could
370make it effectively proprietary.  To prevent this, the GPL assures that
371patents cannot be used to render the program non-free.
372
373  The precise terms and conditions for copying, distribution and
374modification follow.
375
376                       TERMS AND CONDITIONS
377
378  0. Definitions.
379
380  "This License" refers to version 3 of the GNU General Public License.
381
382  "Copyright" also means copyright-like laws that apply to other kinds of
383works, such as semiconductor masks.
384
385  "The Program" refers to any copyrightable work licensed under this
386License.  Each licensee is addressed as "you".  "Licensees" and
387"recipients" may be individuals or organizations.
388
389  To "modify" a work means to copy from or adapt all or part of the work
390in a fashion requiring copyright permission, other than the making of an
391exact copy.  The resulting work is called a "modified version" of the
392earlier work or a work "based on" the earlier work.
393
394  A "covered work" means either the unmodified Program or a work based
395on the Program.
396
397  To "propagate" a work means to do anything with it that, without
398permission, would make you directly or secondarily liable for
399infringement under applicable copyright law, except executing it on a
400computer or modifying a private copy.  Propagation includes copying,
401distribution (with or without modification), making available to the
402public, and in some countries other activities as well.
403
404  To "convey" a work means any kind of propagation that enables other
405parties to make or receive copies.  Mere interaction with a user through
406a computer network, with no transfer of a copy, is not conveying.
407
408  An interactive user interface displays "Appropriate Legal Notices"
409to the extent that it includes a convenient and prominently visible
410feature that (1) displays an appropriate copyright notice, and (2)
411tells the user that there is no warranty for the work (except to the
412extent that warranties are provided), that licensees may convey the
413work under this License, and how to view a copy of this License.  If
414the interface presents a list of user commands or options, such as a
415menu, a prominent item in the list meets this criterion.
416
417  1. Source Code.
418
419  The "source code" for a work means the preferred form of the work
420for making modifications to it.  "Object code" means any non-source
421form of a work.
422
423  A "Standard Interface" means an interface that either is an official
424standard defined by a recognized standards body, or, in the case of
425interfaces specified for a particular programming language, one that
426is widely used among developers working in that language.
427
428  The "System Libraries" of an executable work include anything, other
429than the work as a whole, that (a) is included in the normal form of
430packaging a Major Component, but which is not part of that Major
431Component, and (b) serves only to enable use of the work with that
432Major Component, or to implement a Standard Interface for which an
433implementation is available to the public in source code form.  A
434"Major Component", in this context, means a major essential component
435(kernel, window system, and so on) of the specific operating system
436(if any) on which the executable work runs, or a compiler used to
437produce the work, or an object code interpreter used to run it.
438
439  The "Corresponding Source" for a work in object code form means all
440the source code needed to generate, install, and (for an executable
441work) run the object code and to modify the work, including scripts to
442control those activities.  However, it does not include the work's
443System Libraries, or general-purpose tools or generally available free
444programs which are used unmodified in performing those activities but
445which are not part of the work.  For example, Corresponding Source
446includes interface definition files associated with source files for
447the work, and the source code for shared libraries and dynamically
448linked subprograms that the work is specifically designed to require,
449such as by intimate data communication or control flow between those
450subprograms and other parts of the work.
451
452  The Corresponding Source need not include anything that users
453can regenerate automatically from other parts of the Corresponding
454Source.
455
456  The Corresponding Source for a work in source code form is that
457same work.
458
459  2. Basic Permissions.
460
461  All rights granted under this License are granted for the term of
462copyright on the Program, and are irrevocable provided the stated
463conditions are met.  This License explicitly affirms your unlimited
464permission to run the unmodified Program.  The output from running a
465covered work is covered by this License only if the output, given its
466content, constitutes a covered work.  This License acknowledges your
467rights of fair use or other equivalent, as provided by copyright law.
468
469  You may make, run and propagate covered works that you do not
470convey, without conditions so long as your license otherwise remains
471in force.  You may convey covered works to others for the sole purpose
472of having them make modifications exclusively for you, or provide you
473with facilities for running those works, provided that you comply with
474the terms of this License in conveying all material for which you do
475not control copyright.  Those thus making or running the covered works
476for you must do so exclusively on your behalf, under your direction
477and control, on terms that prohibit them from making any copies of
478your copyrighted material outside their relationship with you.
479
480  Conveying under any other circumstances is permitted solely under
481the conditions stated below.  Sublicensing is not allowed; section 10
482makes it unnecessary.
483
484  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
485
486  No covered work shall be deemed part of an effective technological
487measure under any applicable law fulfilling obligations under article
48811 of the WIPO copyright treaty adopted on 20 December 1996, or
489similar laws prohibiting or restricting circumvention of such
490measures.
491
492  When you convey a covered work, you waive any legal power to forbid
493circumvention of technological measures to the extent such circumvention
494is effected by exercising rights under this License with respect to
495the covered work, and you disclaim any intention to limit operation or
496modification of the work as a means of enforcing, against the work's
497users, your or third parties' legal rights to forbid circumvention of
498technological measures.
499
500  4. Conveying Verbatim Copies.
501
502  You may convey verbatim copies of the Program's source code as you
503receive it, in any medium, provided that you conspicuously and
504appropriately publish on each copy an appropriate copyright notice;
505keep intact all notices stating that this License and any
506non-permissive terms added in accord with section 7 apply to the code;
507keep intact all notices of the absence of any warranty; and give all
508recipients a copy of this License along with the Program.
509
510  You may charge any price or no price for each copy that you convey,
511and you may offer support or warranty protection for a fee.
512
513  5. Conveying Modified Source Versions.
514
515  You may convey a work based on the Program, or the modifications to
516produce it from the Program, in the form of source code under the
517terms of section 4, provided that you also meet all of these conditions:
518
519    a) The work must carry prominent notices stating that you modified
520    it, and giving a relevant date.
521
522    b) The work must carry prominent notices stating that it is
523    released under this License and any conditions added under section
524    7.  This requirement modifies the requirement in section 4 to
525    "keep intact all notices".
526
527    c) You must license the entire work, as a whole, under this
528    License to anyone who comes into possession of a copy.  This
529    License will therefore apply, along with any applicable section 7
530    additional terms, to the whole of the work, and all its parts,
531    regardless of how they are packaged.  This License gives no
532    permission to license the work in any other way, but it does not
533    invalidate such permission if you have separately received it.
534
535    d) If the work has interactive user interfaces, each must display
536    Appropriate Legal Notices; however, if the Program has interactive
537    interfaces that do not display Appropriate Legal Notices, your
538    work need not make them do so.
539
540  A compilation of a covered work with other separate and independent
541works, which are not by their nature extensions of the covered work,
542and which are not combined with it such as to form a larger program,
543in or on a volume of a storage or distribution medium, is called an
544"aggregate" if the compilation and its resulting copyright are not
545used to limit the access or legal rights of the compilation's users
546beyond what the individual works permit.  Inclusion of a covered work
547in an aggregate does not cause this License to apply to the other
548parts of the aggregate.
549
550  6. Conveying Non-Source Forms.
551
552  You may convey a covered work in object code form under the terms
553of sections 4 and 5, provided that you also convey the
554machine-readable Corresponding Source under the terms of this License,
555in one of these ways:
556
557    a) Convey the object code in, or embodied in, a physical product
558    (including a physical distribution medium), accompanied by the
559    Corresponding Source fixed on a durable physical medium
560    customarily used for software interchange.
561
562    b) Convey the object code in, or embodied in, a physical product
563    (including a physical distribution medium), accompanied by a
564    written offer, valid for at least three years and valid for as
565    long as you offer spare parts or customer support for that product
566    model, to give anyone who possesses the object code either (1) a
567    copy of the Corresponding Source for all the software in the
568    product that is covered by this License, on a durable physical
569    medium customarily used for software interchange, for a price no
570    more than your reasonable cost of physically performing this
571    conveying of source, or (2) access to copy the
572    Corresponding Source from a network server at no charge.
573
574    c) Convey individual copies of the object code with a copy of the
575    written offer to provide the Corresponding Source.  This
576    alternative is allowed only occasionally and noncommercially, and
577    only if you received the object code with such an offer, in accord
578    with subsection 6b.
579
580    d) Convey the object code by offering access from a designated
581    place (gratis or for a charge), and offer equivalent access to the
582    Corresponding Source in the same way through the same place at no
583    further charge.  You need not require recipients to copy the
584    Corresponding Source along with the object code.  If the place to
585    copy the object code is a network server, the Corresponding Source
586    may be on a different server (operated by you or a third party)
587    that supports equivalent copying facilities, provided you maintain
588    clear directions next to the object code saying where to find the
589    Corresponding Source.  Regardless of what server hosts the
590    Corresponding Source, you remain obligated to ensure that it is
591    available for as long as needed to satisfy these requirements.
592
593    e) Convey the object code using peer-to-peer transmission, provided
594    you inform other peers where the object code and Corresponding
595    Source of the work are being offered to the general public at no
596    charge under subsection 6d.
597
598  A separable portion of the object code, whose source code is excluded
599from the Corresponding Source as a System Library, need not be
600included in conveying the object code work.
601
602  A "User Product" is either (1) a "consumer product", which means any
603tangible personal property which is normally used for personal, family,
604or household purposes, or (2) anything designed or sold for incorporation
605into a dwelling.  In determining whether a product is a consumer product,
606doubtful cases shall be resolved in favor of coverage.  For a particular
607product received by a particular user, "normally used" refers to a
608typical or common use of that class of product, regardless of the status
609of the particular user or of the way in which the particular user
610actually uses, or expects or is expected to use, the product.  A product
611is a consumer product regardless of whether the product has substantial
612commercial, industrial or non-consumer uses, unless such uses represent
613the only significant mode of use of the product.
614
615  "Installation Information" for a User Product means any methods,
616procedures, authorization keys, or other information required to install
617and execute modified versions of a covered work in that User Product from
618a modified version of its Corresponding Source.  The information must
619suffice to ensure that the continued functioning of the modified object
620code is in no case prevented or interfered with solely because
621modification has been made.
622
623  If you convey an object code work under this section in, or with, or
624specifically for use in, a User Product, and the conveying occurs as
625part of a transaction in which the right of possession and use of the
626User Product is transferred to the recipient in perpetuity or for a
627fixed term (regardless of how the transaction is characterized), the
628Corresponding Source conveyed under this section must be accompanied
629by the Installation Information.  But this requirement does not apply
630if neither you nor any third party retains the ability to install
631modified object code on the User Product (for example, the work has
632been installed in ROM).
633
634  The requirement to provide Installation Information does not include a
635requirement to continue to provide support service, warranty, or updates
636for a work that has been modified or installed by the recipient, or for
637the User Product in which it has been modified or installed.  Access to a
638network may be denied when the modification itself materially and
639adversely affects the operation of the network or violates the rules and
640protocols for communication across the network.
641
642  Corresponding Source conveyed, and Installation Information provided,
643in accord with this section must be in a format that is publicly
644documented (and with an implementation available to the public in
645source code form), and must require no special password or key for
646unpacking, reading or copying.
647
648  7. Additional Terms.
649
650  "Additional permissions" are terms that supplement the terms of this
651License by making exceptions from one or more of its conditions.
652Additional permissions that are applicable to the entire Program shall
653be treated as though they were included in this License, to the extent
654that they are valid under applicable law.  If additional permissions
655apply only to part of the Program, that part may be used separately
656under those permissions, but the entire Program remains governed by
657this License without regard to the additional permissions.
658
659  When you convey a copy of a covered work, you may at your option
660remove any additional permissions from that copy, or from any part of
661it.  (Additional permissions may be written to require their own
662removal in certain cases when you modify the work.)  You may place
663additional permissions on material, added by you to a covered work,
664for which you have or can give appropriate copyright permission.
665
666  Notwithstanding any other provision of this License, for material you
667add to a covered work, you may (if authorized by the copyright holders of
668that material) supplement the terms of this License with terms:
669
670    a) Disclaiming warranty or limiting liability differently from the
671    terms of sections 15 and 16 of this License; or
672
673    b) Requiring preservation of specified reasonable legal notices or
674    author attributions in that material or in the Appropriate Legal
675    Notices displayed by works containing it; or
676
677    c) Prohibiting misrepresentation of the origin of that material, or
678    requiring that modified versions of such material be marked in
679    reasonable ways as different from the original version; or
680
681    d) Limiting the use for publicity purposes of names of licensors or
682    authors of the material; or
683
684    e) Declining to grant rights under trademark law for use of some
685    trade names, trademarks, or service marks; or
686
687    f) Requiring indemnification of licensors and authors of that
688    material by anyone who conveys the material (or modified versions of
689    it) with contractual assumptions of liability to the recipient, for
690    any liability that these contractual assumptions directly impose on
691    those licensors and authors.
692
693  All other non-permissive additional terms are considered "further
694restrictions" within the meaning of section 10.  If the Program as you
695received it, or any part of it, contains a notice stating that it is
696governed by this License along with a term that is a further
697restriction, you may remove that term.  If a license document contains
698a further restriction but permits relicensing or conveying under this
699License, you may add to a covered work material governed by the terms
700of that license document, provided that the further restriction does
701not survive such relicensing or conveying.
702
703  If you add terms to a covered work in accord with this section, you
704must place, in the relevant source files, a statement of the
705additional terms that apply to those files, or a notice indicating
706where to find the applicable terms.
707
708  Additional terms, permissive or non-permissive, may be stated in the
709form of a separately written license, or stated as exceptions;
710the above requirements apply either way.
711
712  8. Termination.
713
714  You may not propagate or modify a covered work except as expressly
715provided under this License.  Any attempt otherwise to propagate or
716modify it is void, and will automatically terminate your rights under
717this License (including any patent licenses granted under the third
718paragraph of section 11).
719
720  However, if you cease all violation of this License, then your
721license from a particular copyright holder is reinstated (a)
722provisionally, unless and until the copyright holder explicitly and
723finally terminates your license, and (b) permanently, if the copyright
724holder fails to notify you of the violation by some reasonable means
725prior to 60 days after the cessation.
726
727  Moreover, your license from a particular copyright holder is
728reinstated permanently if the copyright holder notifies you of the
729violation by some reasonable means, this is the first time you have
730received notice of violation of this License (for any work) from that
731copyright holder, and you cure the violation prior to 30 days after
732your receipt of the notice.
733
734  Termination of your rights under this section does not terminate the
735licenses of parties who have received copies or rights from you under
736this License.  If your rights have been terminated and not permanently
737reinstated, you do not qualify to receive new licenses for the same
738material under section 10.
739
740  9. Acceptance Not Required for Having Copies.
741
742  You are not required to accept this License in order to receive or
743run a copy of the Program.  Ancillary propagation of a covered work
744occurring solely as a consequence of using peer-to-peer transmission
745to receive a copy likewise does not require acceptance.  However,
746nothing other than this License grants you permission to propagate or
747modify any covered work.  These actions infringe copyright if you do
748not accept this License.  Therefore, by modifying or propagating a
749covered work, you indicate your acceptance of this License to do so.
750
751  10. Automatic Licensing of Downstream Recipients.
752
753  Each time you convey a covered work, the recipient automatically
754receives a license from the original licensors, to run, modify and
755propagate that work, subject to this License.  You are not responsible
756for enforcing compliance by third parties with this License.
757
758  An "entity transaction" is a transaction transferring control of an
759organization, or substantially all assets of one, or subdividing an
760organization, or merging organizations.  If propagation of a covered
761work results from an entity transaction, each party to that
762transaction who receives a copy of the work also receives whatever
763licenses to the work the party's predecessor in interest had or could
764give under the previous paragraph, plus a right to possession of the
765Corresponding Source of the work from the predecessor in interest, if
766the predecessor has it or can get it with reasonable efforts.
767
768  You may not impose any further restrictions on the exercise of the
769rights granted or affirmed under this License.  For example, you may
770not impose a license fee, royalty, or other charge for exercise of
771rights granted under this License, and you may not initiate litigation
772(including a cross-claim or counterclaim in a lawsuit) alleging that
773any patent claim is infringed by making, using, selling, offering for
774sale, or importing the Program or any portion of it.
775
776  11. Patents.
777
778  A "contributor" is a copyright holder who authorizes use under this
779License of the Program or a work on which the Program is based.  The
780work thus licensed is called the contributor's "contributor version".
781
782  A contributor's "essential patent claims" are all patent claims
783owned or controlled by the contributor, whether already acquired or
784hereafter acquired, that would be infringed by some manner, permitted
785by this License, of making, using, or selling its contributor version,
786but do not include claims that would be infringed only as a
787consequence of further modification of the contributor version.  For
788purposes of this definition, "control" includes the right to grant
789patent sublicenses in a manner consistent with the requirements of
790this License.
791
792  Each contributor grants you a non-exclusive, worldwide, royalty-free
793patent license under the contributor's essential patent claims, to
794make, use, sell, offer for sale, import and otherwise run, modify and
795propagate the contents of its contributor version.
796
797  In the following three paragraphs, a "patent license" is any express
798agreement or commitment, however denominated, not to enforce a patent
799(such as an express permission to practice a patent or covenant not to
800sue for patent infringement).  To "grant" such a patent license to a
801party means to make such an agreement or commitment not to enforce a
802patent against the party.
803
804  If you convey a covered work, knowingly relying on a patent license,
805and the Corresponding Source of the work is not available for anyone
806to copy, free of charge and under the terms of this License, through a
807publicly available network server or other readily accessible means,
808then you must either (1) cause the Corresponding Source to be so
809available, or (2) arrange to deprive yourself of the benefit of the
810patent license for this particular work, or (3) arrange, in a manner
811consistent with the requirements of this License, to extend the patent
812license to downstream recipients.  "Knowingly relying" means you have
813actual knowledge that, but for the patent license, your conveying the
814covered work in a country, or your recipient's use of the covered work
815in a country, would infringe one or more identifiable patents in that
816country that you have reason to believe are valid.
817
818  If, pursuant to or in connection with a single transaction or
819arrangement, you convey, or propagate by procuring conveyance of, a
820covered work, and grant a patent license to some of the parties
821receiving the covered work authorizing them to use, propagate, modify
822or convey a specific copy of the covered work, then the patent license
823you grant is automatically extended to all recipients of the covered
824work and works based on it.
825
826  A patent license is "discriminatory" if it does not include within
827the scope of its coverage, prohibits the exercise of, or is
828conditioned on the non-exercise of one or more of the rights that are
829specifically granted under this License.  You may not convey a covered
830work if you are a party to an arrangement with a third party that is
831in the business of distributing software, under which you make payment
832to the third party based on the extent of your activity of conveying
833the work, and under which the third party grants, to any of the
834parties who would receive the covered work from you, a discriminatory
835patent license (a) in connection with copies of the covered work
836conveyed by you (or copies made from those copies), or (b) primarily
837for and in connection with specific products or compilations that
838contain the covered work, unless you entered into that arrangement,
839or that patent license was granted, prior to 28 March 2007.
840
841  Nothing in this License shall be construed as excluding or limiting
842any implied license or other defenses to infringement that may
843otherwise be available to you under applicable patent law.
844
845  12. No Surrender of Others' Freedom.
846
847  If conditions are imposed on you (whether by court order, agreement or
848otherwise) that contradict the conditions of this License, they do not
849excuse you from the conditions of this License.  If you cannot convey a
850covered work so as to satisfy simultaneously your obligations under this
851License and any other pertinent obligations, then as a consequence you may
852not convey it at all.  For example, if you agree to terms that obligate you
853to collect a royalty for further conveying from those to whom you convey
854the Program, the only way you could satisfy both those terms and this
855License would be to refrain entirely from conveying the Program.
856
857  13. Use with the GNU Affero General Public License.
858
859  Notwithstanding any other provision of this License, you have
860permission to link or combine any covered work with a work licensed
861under version 3 of the GNU Affero General Public License into a single
862combined work, and to convey the resulting work.  The terms of this
863License will continue to apply to the part which is the covered work,
864but the special requirements of the GNU Affero General Public License,
865section 13, concerning interaction through a network will apply to the
866combination as such.
867
868  14. Revised Versions of this License.
869
870  The Free Software Foundation may publish revised and/or new versions of
871the GNU General Public License from time to time.  Such new versions will
872be similar in spirit to the present version, but may differ in detail to
873address new problems or concerns.
874
875  Each version is given a distinguishing version number.  If the
876Program specifies that a certain numbered version of the GNU General
877Public License "or any later version" applies to it, you have the
878option of following the terms and conditions either of that numbered
879version or of any later version published by the Free Software
880Foundation.  If the Program does not specify a version number of the
881GNU General Public License, you may choose any version ever published
882by the Free Software Foundation.
883
884  If the Program specifies that a proxy can decide which future
885versions of the GNU General Public License can be used, that proxy's
886public statement of acceptance of a version permanently authorizes you
887to choose that version for the Program.
888
889  Later license versions may give you additional or different
890permissions.  However, no additional obligations are imposed on any
891author or copyright holder as a result of your choosing to follow a
892later version.
893
894  15. Disclaimer of Warranty.
895
896  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
897APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
898HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
899OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
900THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
901PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
902IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
903ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
904
905  16. Limitation of Liability.
906
907  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
908WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
909THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
910GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
911USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
912DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
913PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
914EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
915SUCH DAMAGES.
916
917  17. Interpretation of Sections 15 and 16.
918
919  If the disclaimer of warranty and limitation of liability provided
920above cannot be given local legal effect according to their terms,
921reviewing courts shall apply local law that most closely approximates
922an absolute waiver of all civil liability in connection with the
923Program, unless a warranty or assumption of liability accompanies a
924copy of the Program in return for a fee.
925
926Bison Exception
927
928As a special exception, you may create a larger work that contains part or all
929of the Bison parser skeleton and distribute that work under terms of your
930choice, so long as that work isn't itself a parser generator using the skeleton
