1 GNU GENERAL PUBLIC LICENSE

8
9 Everyone is permitted to copy and distribute verbatim copies
10
11 of this license document, but changing it is not allowed.
12
13
14
15 Preamble
16
17
18
19 The GNU General Public License is a free, copyleft license for
20
21 software and other kinds of works.
22
23
24
25 The licenses for most software and other practical works are designed
26
27 to take away your freedom to share and change the works. By contrast,
28
29 the GNU General Public License is intended to guarantee your freedom to
30
31 share and change all versions of a program--to make sure it remains free
32
33 software for all its users. We, the Free Software Foundation, use the
34
35 GNU General Public License for most of our software; it applies also to
36
37 any other work released this way by its authors. You can apply it to
38
39 your programs, too.
40
41
42
43 When we speak of free software, we are referring to freedom, not
44
45 price. Our General Public Licenses are designed to make sure that you
46
47 have the freedom to distribute copies of free software (and charge for
48
49 them if you wish), that you receive source code or can get it if you
50
51 want it, that you can change the software or use pieces of it in new
52
53 free programs, and that you know you can do these things.
54
55
56
57 To protect your rights, we need to prevent others from denying you
58
59 these rights or asking you to surrender the rights. Therefore, you have
60
61 certain responsibilities if you distribute copies of the software, or if
62
63 you modify it: responsibilities to respect the freedom of others.
64
65
66
67 For example, if you distribute copies of such a program, whether
68
69 gratis or for a fee, you must pass on to the recipients the same
70
71 freedoms that you received. You must make sure that they, too, receive
72
73 or can get the source code. And you must show them these terms so they
74
75 know their rights.
76
77
78
79 Developers that use the GNU GPL protect your rights with two steps:
80
81 (1) assert copyright on the software, and (2) offer you this License
82
83 giving you legal permission to copy, distribute and/or modify it.
84
85
86
87 For the developers' and authors' protection, the GPL clearly explains
88
89 that there is no warranty for this free software. For both users' and
90
91 authors' sake, the GPL requires that modified versions be marked as
92
93 changed, so that their problems will not be attributed erroneously to
94
95 authors of previous versions.
96
97
98
99 Some devices are designed to deny users access to install or run
100
101 modified versions of the software inside them, although the manufacturer
102
103 can do so. This is fundamentally incompatible with the aim of
104
105 protecting users' freedom to change the software. The systematic
106
107 pattern of such abuse occurs in the area of products for individuals to
108
109 use, which is precisely where it is most unacceptable. Therefore, we
110
111 have designed this version of the GPL to prohibit the practice for those
112
113 products. If such problems arise substantially in other domains, we
114
115 stand ready to extend this provision to those domains in future versions
116
117 of the GPL, as needed to protect the freedom of users.
118
119
120
121 Finally, every program is threatened constantly by software patents.
122
123 States should not allow patents to restrict development and use of
124
125 software on general-purpose computers, but in those that do, we wish to
126
127 avoid the special danger that patents applied to a free program could
128
129 make it effectively proprietary. To prevent this, the GPL assures that
130
131 patents cannot be used to render the program non-free.
132
133
134
135 The precise terms and conditions for copying, distribution and
136
137 modification follow.
138
139
140
141 TERMS AND CONDITIONS
142
143
144
145 0. Definitions.
146
147
148
149 "This License" refers to version 3 of the GNU General Public License.
150
151
152
153 "Copyright" also means copyright-like laws that apply to other kinds of
154
155 works, such as semiconductor masks.
156
157
158
159 "The Program" refers to any copyrightable work licensed under this
160
161 License. Each licensee is addressed as "you". "Licensees" and
162
163 "recipients" may be individuals or organizations.
164
165
166
167 To "modify" a work means to copy from or adapt all or part of the work
168
169 in a fashion requiring copyright permission, other than the making of an
170
171 exact copy. The resulting work is called a "modified version" of the
172
173 earlier work or a work "based on" the earlier work.
174
175
176
177 A "covered work" means either the unmodified Program or a work based
178
179 on the Program.
180
181
182
183 To "propagate" a work means to do anything with it that, without
184
185 permission, would make you directly or secondarily liable for
186
187 infringement under applicable copyright law, except executing it on a
188
189 computer or modifying a private copy. Propagation includes copying,
190
191 distribution (with or without modification), making available to the
192
193 public, and in some countries other activities as well.
194
195
196
197 To "convey" a work means any kind of propagation that enables other
198
199 parties to make or receive copies. Mere interaction with a user through
200
201 a computer network, with no transfer of a copy, is not conveying.
202
203
204
205 An interactive user interface displays "Appropriate Legal Notices"
206
207 to the extent that it includes a convenient and prominently visible
208
209 feature that (1) displays an appropriate copyright notice, and (2)
210
211 tells the user that there is no warranty for the work (except to the
212
213 extent that warranties are provided), that licensees may convey the
214
215 work under this License, and how to view a copy of this License. If
216
217 the interface presents a list of user commands or options, such as a
218
219 menu, a prominent item in the list meets this criterion.
220
221
222
223 1. Source Code.
224
225
226
227 The "source code" for a work means the preferred form of the work
228
229 for making modifications to it. "Object code" means any non-source
230
231 form of a work.
232
233
234
235 A "Standard Interface" means an interface that either is an official
236
237 standard defined by a recognized standards body, or, in the case of
238
239 interfaces specified for a particular programming language, one that
240
241 is widely used among developers working in that language.
242
243
244
245 The "System Libraries" of an executable work include anything, other
246
247 than the work as a whole, that (a) is included in the normal form of
248
249 packaging a Major Component, but which is not part of that Major
250
251 Component, and (b) serves only to enable use of the work with that
252
253 Major Component, or to implement a Standard Interface for which an
254
255 implementation is available to the public in source code form. A
256
257 "Major Component", in this context, means a major essential component
258
259 (kernel, window system, and so on) of the specific operating system
260
261 (if any) on which the executable work runs, or a compiler used to
262
263 produce the work, or an object code interpreter used to run it.
264
265
266
267 The "Corresponding Source" for a work in object code form means all
268
269 the source code needed to generate, install, and (for an executable
270
271 work) run the object code and to modify the work, including scripts to
272
273 control those activities. However, it does not include the work's
274
275 System Libraries, or general-purpose tools or generally available free
276
277 programs which are used unmodified in performing those activities but
278
279 which are not part of the work. For example, Corresponding Source
280
281 includes interface definition files associated with source files for
282
283 the work, and the source code for shared libraries and dynamically
284
285 linked subprograms that the work is specifically designed to require,
286
287 such as by intimate data communication or control flow between those
288
289 subprograms and other parts of the work.
290
291
292
293 The Corresponding Source need not include anything that users
294
295 can regenerate automatically from other parts of the Corresponding
296
297 Source.
298
299
300
301 The Corresponding Source for a work in source code form is that
302
303 same work.
304
305
306
307 2. Basic Permissions.
308
309
310
311 All rights granted under this License are granted for the term of
312
313 copyright on the Program, and are irrevocable provided the stated
314
315 conditions are met. This License explicitly affirms your unlimited
316
317 permission to run the unmodified Program. The output from running a
318
319 covered work is covered by this License only if the output, given its
320
321 content, constitutes a covered work. This License acknowledges your
322
323 rights of fair use or other equivalent, as provided by copyright law.
324
325
326
327 You may make, run and propagate covered works that you do not
328
329 convey, without conditions so long as your license otherwise remains
330
331 in force. You may convey covered works to others for the sole purpose
332
333 of having them make modifications exclusively for you, or provide you
334
335 with facilities for running those works, provided that you comply with
336
337 the terms of this License in conveying all material for which you do
338
339 not control copyright. Those thus making or running the covered works
340
341 for you must do so exclusively on your behalf, under your direction
342
343 and control, on terms that prohibit them from making any copies of
344
345 your copyrighted material outside their relationship with you.
346
347
348
349 Conveying under any other circumstances is permitted solely under
350
351 the conditions stated below. Sublicensing is not allowed; section 10
352
353 makes it unnecessary.
354
355
356
357 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
358
359
360
361 No covered work shall be deemed part of an effective technological
362
363 measure under any applicable law fulfilling obligations under article
364
365 11 of the WIPO copyright treaty adopted on 20 December 1996, or
366
367 similar laws prohibiting or restricting circumvention of such
368
369 measures.
370
371
372
373 When you convey a covered work, you waive any legal power to forbid
374
375 circumvention of technological measures to the extent such circumvention
376
377 is effected by exercising rights under this License with respect to
378
379 the covered work, and you disclaim any intention to limit operation or
380
381 modification of the work as a means of enforcing, against the work's
382
383 users, your or third parties' legal rights to forbid circumvention of
384
385 technological measures.
386
387
388
389 4. Conveying Verbatim Copies.
390
391
392
393 You may convey verbatim copies of the Program's source code as you
394
395 receive it, in any medium, provided that you conspicuously and
396
397 appropriately publish on each copy an appropriate copyright notice;
398
399 keep intact all notices stating that this License and any
400
401 non-permissive terms added in accord with section 7 apply to the code;
402
403 keep intact all notices of the absence of any warranty; and give all
404
405 recipients a copy of this License along with the Program.
406
407
408
409 You may charge any price or no price for each copy that you convey,
410
411 and you may offer support or warranty protection for a fee.
412
413
414
415 5. Conveying Modified Source Versions.
416
417
418
419 You may convey a work based on the Program, or the modifications to
420
421 produce it from the Program, in the form of source code under the
422
423 terms of section 4, provided that you also meet all of these conditions:
424
425
426
427 a) The work must carry prominent notices stating that you modified
428
429 it, and giving a relevant date.
430
431
432
433 b) The work must carry prominent notices stating that it is
434
435 released under this License and any conditions added under section
436
437 7. This requirement modifies the requirement in section 4 to
438
439 "keep intact all notices".
440
441
442
443 c) You must license the entire work, as a whole, under this
444
445 License to anyone who comes into possession of a copy. This
446
447 License will therefore apply, along with any applicable section 7
448
449 additional terms, to the whole of the work, and all its parts,
450
451 regardless of how they are packaged. This License gives no
452
453 permission to license the work in any other way, but it does not
454
455 invalidate such permission if you have separately received it.
456
457
458
459 d) If the work has interactive user interfaces, each must display
460
461 Appropriate Legal Notices; however, if the Program has interactive
462
463 interfaces that do not display Appropriate Legal Notices, your
464
465 work need not make them do so.
466
467
468
469 A compilation of a covered work with other separate and independent
470
471 works, which are not by their nature extensions of the covered work,
472
473 and which are not combined with it such as to form a larger program,
474
475 in or on a volume of a storage or distribution medium, is called an
476
477 "aggregate" if the compilation and its resulting copyright are not
478
479 used to limit the access or legal rights of the compilation's users
480
481 beyond what the individual works permit. Inclusion of a covered work
482
483 in an aggregate does not cause this License to apply to the other
484
485 parts of the aggregate.
486
487
488
489 6. Conveying Non-Source Forms.
490
491
492
493 You may convey a covered work in object code form under the terms
494
495 of sections 4 and 5, provided that you also convey the
496
497 machine-readable Corresponding Source under the terms of this License,
498
499 in one of these ways:
500
501
502
503 a) Convey the object code in, or embodied in, a physical product
504
505 (including a physical distribution medium), accompanied by the
506
507 Corresponding Source fixed on a durable physical medium
508
509 customarily used for software interchange.
510
511
512
513 b) Convey the object code in, or embodied in, a physical product
514
515 (including a physical distribution medium), accompanied by a
516
517 written offer, valid for at least three years and valid for as
518
519 long as you offer spare parts or customer support for that product
520
521 model, to give anyone who possesses the object code either (1) a
522
523 copy of the Corresponding Source for all the software in the
524
525 product that is covered by this License, on a durable physical
526
527 medium customarily used for software interchange, for a price no
528
529 more than your reasonable cost of physically performing this
530
531 conveying of source, or (2) access to copy the
532
533 Corresponding Source from a network server at no charge.
534
535
536
537 c) Convey individual copies of the object code with a copy of the
538
539 written offer to provide the Corresponding Source. This
540
541 alternative is allowed only occasionally and noncommercially, and
542
543 only if you received the object code with such an offer, in accord
544
545 with subsection 6b.
546
547
548
549 d) Convey the object code by offering access from a designated
550
551 place (gratis or for a charge), and offer equivalent access to the
552
553 Corresponding Source in the same way through the same place at no
554
555 further charge. You need not require recipients to copy the
556
557 Corresponding Source along with the object code. If the place to
558
559 copy the object code is a network server, the Corresponding Source
560
561 may be on a different server (operated by you or a third party)
562
563 that supports equivalent copying facilities, provided you maintain
564
565 clear directions next to the object code saying where to find the
566
567 Corresponding Source. Regardless of what server hosts the
568
569 Corresponding Source, you remain obligated to ensure that it is
570
571 available for as long as needed to satisfy these requirements.
572
573
574
575 e) Convey the object code using peer-to-peer transmission, provided
576
577 you inform other peers where the object code and Corresponding
578
579 Source of the work are being offered to the general public at no
580
581 charge under subsection 6d.
582
583
584
585 A separable portion of the object code, whose source code is excluded
586
587 from the Corresponding Source as a System Library, need not be
588
589 included in conveying the object code work.
590
591
592
593 A "User Product" is either (1) a "consumer product", which means any
594
595 tangible personal property which is normally used for personal, family,
596
597 or household purposes, or (2) anything designed or sold for incorporation
598
599 into a dwelling. In determining whether a product is a consumer product,
600
601 doubtful cases shall be resolved in favor of coverage. For a particular
602
603 product received by a particular user, "normally used" refers to a
604
605 typical or common use of that class of product, regardless of the status
606
607 of the particular user or of the way in which the particular user
608
609 actually uses, or expects or is expected to use, the product. A product
610
611 is a consumer product regardless of whether the product has substantial
612
613 commercial, industrial or non-consumer uses, unless such uses represent
614
615 the only significant mode of use of the product.
616
617
618
619 "Installation Information" for a User Product means any methods,
620
621 procedures, authorization keys, or other information required to install
622
623 and execute modified versions of a covered work in that User Product from
624
625 a modified version of its Corresponding Source. The information must
626
627 suffice to ensure that the continued functioning of the modified object
628
629 code is in no case prevented or interfered with solely because
630
631 modification has been made.
632
633
634
635 If you convey an object code work under this section in, or with, or
636
637 specifically for use in, a User Product, and the conveying occurs as
638
639 part of a transaction in which the right of possession and use of the
640
641 User Product is transferred to the recipient in perpetuity or for a
642
643 fixed term (regardless of how the transaction is characterized), the
644
645 Corresponding Source conveyed under this section must be accompanied
646
647 by the Installation Information. But this requirement does not apply
648
649 if neither you nor any third party retains the ability to install
650
651 modified object code on the User Product (for example, the work has
652
653 been installed in ROM).
654
655
656
657 The requirement to provide Installation Information does not include a
658
659 requirement to continue to provide support service, warranty, or updates
660
661 for a work that has been modified or installed by the recipient, or for
662
663 the User Product in which it has been modified or installed. Access to a
664
665 network may be denied when the modification itself materially and
666
667 adversely affects the operation of the network or violates the rules and
668
669 protocols for communication across the network.
670
671
672
673 Corresponding Source conveyed, and Installation Information provided,
674
675 in accord with this section must be in a format that is publicly
676
677 documented (and with an implementation available to the public in
678
679 source code form), and must require no special password or key for
680
681 unpacking, reading or copying.
682
683
684
685 7. Additional Terms.
686
687
688
689 "Additional permissions" are terms that supplement the terms of this
690
691 License by making exceptions from one or more of its conditions.
692
693 Additional permissions that are applicable to the entire Program shall
694
695 be treated as though they were included in this License, to the extent
696
697 that they are valid under applicable law. If additional permissions
698
699 apply only to part of the Program, that part may be used separately
700
701 under those permissions, but the entire Program remains governed by
702
703 this License without regard to the additional permissions.
704
705
706
707 When you convey a copy of a covered work, you may at your option
708
709 remove any additional permissions from that copy, or from any part of
710
711 it. (Additional permissions may be written to require their own
712
713 removal in certain cases when you modify the work.) You may place
714
715 additional permissions on material, added by you to a covered work,
716
717 for which you have or can give appropriate copyright permission.
718
719
720
721 Notwithstanding any other provision of this License, for material you
722
723 add to a covered work, you may (if authorized by the copyright holders of
724
725 that material) supplement the terms of this License with terms:
726
727
728
729 a) Disclaiming warranty or limiting liability differently from the
730
731 terms of sections 15 and 16 of this License; or
732
733
734
735 b) Requiring preservation of specified reasonable legal notices or
736
737 author attributions in that material or in the Appropriate Legal
738
739 Notices displayed by works containing it; or
740
741
742
743 c) Prohibiting misrepresentation of the origin of that material, or
744
745 requiring that modified versions of such material be marked in
746
747 reasonable ways as different from the original version; or
748
749
750
751 d) Limiting the use for publicity purposes of names of licensors or
752
753 authors of the material; or
754
755
756
757 e) Declining to grant rights under trademark law for use of some
758
759 trade names, trademarks, or service marks; or
760
761
762
763 f) Requiring indemnification of licensors and authors of that
764
765 material by anyone who conveys the material (or modified versions of
766
767 it) with contractual assumptions of liability to the recipient, for
768
769 any liability that these contractual assumptions directly impose on
770
771 those licensors and authors.
772
773
774
775 All other non-permissive additional terms are considered "further
776
777 restrictions" within the meaning of section 10. If the Program as you
778
779 received it, or any part of it, contains a notice stating that it is
780
781 governed by this License along with a term that is a further
782
783 restriction, you may remove that term. If a license document contains
784
785 a further restriction but permits relicensing or conveying under this
786
787 License, you may add to a covered work material governed by the terms
788
789 of that license document, provided that the further restriction does
790
791 not survive such relicensing or conveying.
792
793
794
795 If you add terms to a covered work in accord with this section, you
796
797 must place, in the relevant source files, a statement of the
798
799 additional terms that apply to those files, or a notice indicating
800
801 where to find the applicable terms.
802
803
804
805 Additional terms, permissive or non-permissive, may be stated in the
806
807 form of a separately written license, or stated as exceptions;
808
809 the above requirements apply either way.
810
811
812
813 8. Termination.
814
815
816
817 You may not propagate or modify a covered work except as expressly
818
819 provided under this License. Any attempt otherwise to propagate or
820
821 modify it is void, and will automatically terminate your rights under
822
823 this License (including any patent licenses granted under the third
824
825 paragraph of section 11).
826
827
828
829 However, if you cease all violation of this License, then your
830
831 license from a particular copyright holder is reinstated (a)
832
833 provisionally, unless and until the copyright holder explicitly and
834
835 finally terminates your license, and (b) permanently, if the copyright
836
837 holder fails to notify you of the violation by some reasonable means
838
839 prior to 60 days after the cessation.
840
841
842
843 Moreover, your license from a particular copyright holder is
844
845 reinstated permanently if the copyright holder notifies you of the
846
847 violation by some reasonable means, this is the first time you have
848
849 received notice of violation of this License (for any work) from that
850
851 copyright holder, and you cure the violation prior to 30 days after
852
853 your receipt of the notice.
854
855
856
857 Termination of your rights under this section does not terminate the
858
859 licenses of parties who have received copies or rights from you under
860
861 this License. If your rights have been terminated and not permanently
862
863 reinstated, you do not qualify to receive new licenses for the same
864
865 material under section 10.
866
867
868
869 9. Acceptance Not Required for Having Copies.
870
871
872
873 You are not required to accept this License in order to receive or
874
875 run a copy of the Program. Ancillary propagation of a covered work
876
877 occurring solely as a consequence of using peer-to-peer transmission
878
879 to receive a copy likewise does not require acceptance. However,
880
881 nothing other than this License grants you permission to propagate or
882
883 modify any covered work. These actions infringe copyright if you do
884
885 not accept this License. Therefore, by modifying or propagating a
886
887 covered work, you indicate your acceptance of this License to do so.
888
889
890
891 10. Automatic Licensing of Downstream Recipients.
892
893
894
895 Each time you convey a covered work, the recipient automatically
896
897 receives a license from the original licensors, to run, modify and
898
899 propagate that work, subject to this License. You are not responsible
900
901 for enforcing compliance by third parties with this License.
902
903
904
905 An "entity transaction" is a transaction transferring control of an
906
907 organization, or substantially all assets of one, or subdividing an
908
909 organization, or merging organizations. If propagation of a covered
910
911 work results from an entity transaction, each party to that
912
913 transaction who receives a copy of the work also receives whatever
914
915 licenses to the work the party's predecessor in interest had or could
916
917 give under the previous paragraph, plus a right to possession of the
918
919 Corresponding Source of the work from the predecessor in interest, if
920
921 the predecessor has it or can get it with reasonable efforts.
922
923
924
925 You may not impose any further restrictions on the exercise of the
926
927 rights granted or affirmed under this License. For example, you may
928
929 not impose a license fee, royalty, or other charge for exercise of
930
931 rights granted under this License, and you may not initiate litigation
932
933 (including a cross-claim or counterclaim in a lawsuit) alleging that
934
935 any patent claim is infringed by making, using, selling, offering for
936
937 sale, or importing the Program or any portion of it.
938
939
940
941 11. Patents.
942
943
944
945 A "contributor" is a copyright holder who authorizes use under this
946
947 License of the Program or a work on which the Program is based. The
948
949 work thus licensed is called the contributor's "contributor version".
950
951
952
953 A contributor's "essential patent claims" are all patent claims
954
955 owned or controlled by the contributor, whether already acquired or
956
957 hereafter acquired, that would be infringed by some manner, permitted
958
959 by this License, of making, using, or selling its contributor version,
960
961 but do not include claims that would be infringed only as a
962
963 consequence of further modification of the contributor version. For
964
965 purposes of this definition, "control" includes the right to grant
966
967 patent sublicenses in a manner consistent with the requirements of
968
969 this License.
970
971
972
973 Each contributor grants you a non-exclusive, worldwide, royalty-free
974
975 patent license under the contributor's essential patent claims, to
976
977 make, use, sell, offer for sale, import and otherwise run, modify and
978
979 propagate the contents of its contributor version.
980
981
982
983 In the following three paragraphs, a "patent license" is any express
984
985 agreement or commitment, however denominated, not to enforce a patent
986
987 (such as an express permission to practice a patent or covenant not to
988
989 sue for patent infringement). To "grant" such a patent license to a
990
991 party means to make such an agreement or commitment not to enforce a
992
993 patent against the party.
994
995
996
997 If you convey a covered work, knowingly relying on a patent license,
998
999 and the Corresponding Source of the work is not available for anyone
1000
1001 to copy, free of charge and under the terms of this License, through a
1002
1003 publicly available network server or other readily accessible means,
1004
1005 then you must either (1) cause the Corresponding Source to be so
1006
1007 available, or (2) arrange to deprive yourself of the benefit of the
1008
1009 patent license for this particular work, or (3) arrange, in a manner
1010
1011 consistent with the requirements of this License, to extend the patent
1012
1013 license to downstream recipients. "Knowingly relying" means you have
1014
1015 actual knowledge that, but for the patent license, your conveying the
1016
1017 covered work in a country, or your recipient's use of the covered work
1018
1019 in a country, would infringe one or more identifiable patents in that
1020
1021 country that you have reason to believe are valid.
1022
1023
1024
1025 If, pursuant to or in connection with a single transaction or
1026
1027 arrangement, you convey, or propagate by procuring conveyance of, a
1028
1029 covered work, and grant a patent license to some of the parties
1030
1031 receiving the covered work authorizing them to use, propagate, modify
1032
1033 or convey a specific copy of the covered work, then the patent license
1034
1035 you grant is automatically extended to all recipients of the covered
1036
1037 work and works based on it.
1038
1039
1040
1041 A patent license is "discriminatory" if it does not include within
1042
1043 the scope of its coverage, prohibits the exercise of, or is
1044
1045 conditioned on the non-exercise of one or more of the rights that are
1046
1047 specifically granted under this License. You may not convey a covered
1048
1049 work if you are a party to an arrangement with a third party that is
1050
1051 in the business of distributing software, under which you make payment
1052
1053 to the third party based on the extent of your activity of conveying
1054
1055 the work, and under which the third party grants, to any of the
1056
1057 parties who would receive the covered work from you, a discriminatory
1058
1059 patent license (a) in connection with copies of the covered work
1060
1061 conveyed by you (or copies made from those copies), or (b) primarily
1062
1063 for and in connection with specific products or compilations that
1064
1065 contain the covered work, unless you entered into that arrangement,
1066
1067 or that patent license was granted, prior to 28 March 2007.
1068
1069
1070
1071 Nothing in this License shall be construed as excluding or limiting
1072
1073 any implied license or other defenses to infringement that may
1074
1075 otherwise be available to you under applicable patent law.
1076
1077
1078
1079 12. No Surrender of Others' Freedom.
1080
1081
1082
1083 If conditions are imposed on you (whether by court order, agreement or
1084
1085 otherwise) that contradict the conditions of this License, they do not
1086
1087 excuse you from the conditions of this License. If you cannot convey a
1088
1089 covered work so as to satisfy simultaneously your obligations under this
1090
1091 License and any other pertinent obligations, then as a consequence you may
1092
1093 not convey it at all. For example, if you agree to terms that obligate you
1094
1095 to collect a royalty for further conveying from those to whom you convey
1096
1097 the Program, the only way you could satisfy both those terms and this
1098
1099 License would be to refrain entirely from conveying the Program.
1100
1101
1102
1103 13. Use with the GNU Affero General Public License.
1104
1105
1106
1107 Notwithstanding any other provision of this License, you have
1108
1109 permission to link or combine any covered work with a work licensed
1110
1111 under version 3 of the GNU Affero General Public License into a single
1112
1113 combined work, and to convey the resulting work. The terms of this
1114
1115 License will continue to apply to the part which is the covered work,
1116
1117 but the special requirements of the GNU Affero General Public License,
1118
1119 section 13, concerning interaction through a network will apply to the
1120
1121 combination as such.
1122
1123
1124
1125 14. Revised Versions of this License.
1126
1127
1128
1129 The Free Software Foundation may publish revised and/or new versions of
1130
1131 the GNU General Public License from time to time. Such new versions will
1132
1133 be similar in spirit to the present version, but may differ in detail to
1134
1135 address new problems or concerns.
1136
1137
1138
1139 Each version is given a distinguishing version number. If the
1140
1141 Program specifies that a certain numbered version of the GNU General
1142
1143 Public License "or any later version" applies to it, you have the
1144
1145 option of following the terms and conditions either of that numbered
1146
1147 version or of any later version published by the Free Software
1148
1149 Foundation. If the Program does not specify a version number of the
1150
1151 GNU General Public License, you may choose any version ever published
1152
1153 by the Free Software Foundation.
1154
1155
1156
1157 If the Program specifies that a proxy can decide which future
1158
1159 versions of the GNU General Public License can be used, that proxy's
1160
1161 public statement of acceptance of a version permanently authorizes you
1162
1163 to choose that version for the Program.
1164
1165
1166
1167 Later license versions may give you additional or different
1168
1169 permissions. However, no additional obligations are imposed on any
1170
1171 author or copyright holder as a result of your choosing to follow a
1172
1173 later version.
1174
1175
1176
1177 15. Disclaimer of Warranty.
1178
1179
1180
1181 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
1182
1183 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
1184
1185 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
1186
1187 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
1188
1189 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
1190
1191 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
1192
1193 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
1194
1195 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
1196
1197
1198
1199 16. Limitation of Liability.
1200
1201
1202
1203 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
1204
1205 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
1206
1207 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
1208
1209 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
1210
1211 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
1212
1213 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
1214
1215 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
1216
1217 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
1218
1219 SUCH DAMAGES.
1220
1221
1222
1223 17. Interpretation of Sections 15 and 16.
1224
1225
1226
1227 If the disclaimer of warranty and limitation of liability provided
1228
1229 above cannot be given local legal effect according to their terms,
1230
1231 reviewing courts shall apply local law that most closely approximates
1232
1233 an absolute waiver of all civil liability in connection with the
1234
1235 Program, unless a warranty or assumption of liability accompanies a
1236
1237 copy of the Program in return for a fee.
1238
1239
1240
1241 END OF TERMS AND CONDITIONS
1242
1243
1244
1245 How to Apply These Terms to Your New Programs
1246
1247
1248
1249 If you develop a new program, and you want it to be of the greatest
1250
1251 possible use to the public, the best way to achieve this is to make it
1252
1253 free software which everyone can redistribute and change under these terms.
1254
1255
1256
1257 To do so, attach the following notices to the program. It is safest
1258
1259 to attach them to the start of each source file to most effectively
1260
1261 state the exclusion of warranty; and each file should have at least
1262
1263 the "copyright" line and a pointer to where the full notice is found.
1264
1265
1266
1267 <one line to give the program's name and a brief idea of what it does.>
1268
1269 Copyright (C) <year> <name of author>
1270
1271
1272
1273 This program is free software: you can redistribute it and/or modify
1274
1275 it under the terms of the GNU General Public License as published by
1276
1277 the Free Software Foundation, either version 3 of the License, or
1278
1279 (at your option) any later version.
1280
1281
1282
1283 This program is distributed in the hope that it will be useful,
1284
1285 but WITHOUT ANY WARRANTY; without even the implied warranty of
1286
1287 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
1288
1289 GNU General Public License for more details.
1290
1291
1292
1293 You should have received a copy of the GNU General Public License
1294
1295 along with this program. If not, see <http://www.gnu.org/licenses/>.
1296
1297
1298
1299 Also add information on how to contact you by electronic and paper mail.
1300
1301
1302
1303 If the program does terminal interaction, make it output a short
1304
1305 notice like this when it starts in an interactive mode:
1306
1307
1308
1309 <program> Copyright (C) <year> <name of author>
1310
1311 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
1312
1313 This is free software, and you are welcome to redistribute it
1314
1315 under certain conditions; type `show c' for details.
1316
1317
1318
1319 The hypothetical commands `show w' and `show c' should show the appropriate
1320
1321 parts of the General Public License. Of course, your program's commands
1322
1323 might be different; for a GUI interface, you would use an "about box".
1324
1325
1326
1327 You should also get your employer (if you work as a programmer) or school,
1328
1329 if any, to sign a "copyright disclaimer" for the program, if necessary.

1334
1335
1336
1337 The GNU General Public License does not permit incorporating your program
1338
1339 into proprietary programs. If your program is a subroutine library, you
1340
1341 may consider it more useful to permit linking proprietary applications with
1342
1343 the library. If this is what you want to do, use the GNU Lesser General
1344
1345 Public License instead of this License. But first, please read
