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