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