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