38 | GNU AFFERO GENERAL PUBLIC LICENSE |
39 | Version 3, 19 November 2007 | |
40 | ||
41 | Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> | |
42 | Everyone is permitted to copy and distribute verbatim copies | |
43 | of this license document, but changing it is not allowed. | |
44 | ||
45 | Preamble | |
46 | ||
47 | The GNU Affero General Public License is a free, copyleft license | |
48 | for software and other kinds of works, specifically designed to ensure | |
49 | cooperation with the community in the case of network server software. | |
50 | ||
51 | The licenses for most software and other practical works are | |
52 | designed to take away your freedom to share and change the works. By | |
53 | contrast, our General Public Licenses are intended to guarantee your | |
54 | freedom to share and change all versions of a program--to make sure it | |
55 | remains free software for all its users. | |
56 | ||
57 | When we speak of free software, we are referring to freedom, not | |
58 | price. Our General Public Licenses are designed to make sure that you | |
59 | have the freedom to distribute copies of free software (and charge for | |
60 | them if you wish), that you receive source code or can get it if you | |
61 | want it, that you can change the software or use pieces of it in new | |
62 | free programs, and that you know you can do these things. | |
63 | ||
64 | Developers that use our General Public Licenses protect your rights | |
65 | with two steps: (1) assert copyright on the software, and (2) offer | |
66 | you this License which gives you legal permission to copy, distribute | |
67 | and/or modify the software. | |
68 | ||
69 | A secondary benefit of defending all users' freedom is that | |
70 | improvements made in alternate versions of the program, if they | |
71 | receive widespread use, become available for other developers to | |
72 | incorporate. Many developers of free software are heartened and | |
73 | encouraged by the resulting cooperation. However, in the case of | |
74 | software used on network servers, this result may fail to come about. | |
75 | The GNU General Public License permits making a modified version and | |
76 | letting the public access it on a server without ever releasing its | |
77 | source code to the public. | |
78 | ||
79 | The GNU Affero General Public License is designed specifically to | |
80 | ensure that, in such cases, the modified source code becomes available | |
81 | to the community. It requires the operator of a network server to | |
82 | provide the source code of the modified version running there to the | |
83 | users of that server. Therefore, public use of a modified version, on | |
84 | a publicly accessible server, gives the public access to the source | |
85 | code of the modified version. | |
86 | ||
87 | An older license, called the Affero General Public License and | |
88 | published by Affero, was designed to accomplish similar goals. This is | |
89 | a different license, not a version of the Affero GPL, but Affero has | |
90 | released a new version of the Affero GPL which permits relicensing under | |
91 | this license. | |
92 | ||
93 | The precise terms and conditions for copying, distribution and | |
94 | modification follow. | |
95 | ||
96 | TERMS AND CONDITIONS | |
97 | ||
98 | 0. Definitions. | |
99 | ||
100 | "This License" refers to version 3 of the GNU Affero General Public | |
101 | License. | |
102 | ||
103 | "Copyright" also means copyright-like laws that apply to other kinds | |
104 | of works, such as semiconductor masks. | |
105 | ||
106 | "The Program" refers to any copyrightable work licensed under this | |
107 | License. Each licensee is addressed as "you". "Licensees" and | |
108 | "recipients" may be individuals or organizations. | |
109 | ||
110 | To "modify" a work means to copy from or adapt all or part of the work | |
111 | in a fashion requiring copyright permission, other than the making of an | |
112 | exact copy. The resulting work is called a "modified version" of the | |
113 | earlier work or a work "based on" the earlier work. | |
114 | ||
115 | A "covered work" means either the unmodified Program or a work based | |
116 | on the Program. | |
117 | ||
118 | To "propagate" a work means to do anything with it that, without | |
119 | permission, would make you directly or secondarily liable for | |
120 | infringement under applicable copyright law, except executing it on a | |
121 | computer or modifying a private copy. Propagation includes copying, | |
122 | distribution (with or without modification), making available to the | |
123 | public, and in some countries other activities as well. | |
124 | ||
125 | To "convey" a work means any kind of propagation that enables other | |
126 | parties to make or receive copies. Mere interaction with a user through | |
127 | a computer network, with no transfer of a copy, is not conveying. | |
128 | ||
129 | An interactive user interface displays "Appropriate Legal Notices" | |
130 | to the extent that it includes a convenient and prominently visible | |
131 | feature that (1) displays an appropriate copyright notice, and (2) | |
132 | tells the user that there is no warranty for the work (except to the | |
133 | extent that warranties are provided), that licensees may convey the | |
134 | work under this License, and how to view a copy of this License. If | |
135 | the interface presents a list of user commands or options, such as a | |
136 | menu, a prominent item in the list meets this criterion. | |
137 | ||
138 | 1. Source Code. | |
139 | ||
140 | The "source code" for a work means the preferred form of the work | |
141 | for making modifications to it. "Object code" means any non-source | |
142 | form of a work. | |
143 | ||
144 | A "Standard Interface" means an interface that either is an official | |
145 | standard defined by a recognized standards body, or, in the case of | |
146 | interfaces specified for a particular programming language, one that | |
147 | is widely used among developers working in that language. | |
148 | ||
149 | The "System Libraries" of an executable work include anything, other | |
150 | than the work as a whole, that (a) is included in the normal form of | |
151 | packaging a Major Component, but which is not part of that Major | |
152 | Component, and (b) serves only to enable use of the work with that | |
153 | Major Component, or to implement a Standard Interface for which an | |
154 | implementation is available to the public in source code form. A | |
155 | "Major Component", in this context, means a major essential component | |
156 | (kernel, window system, and so on) of the specific operating system | |
157 | (if any) on which the executable work runs, or a compiler used to | |
158 | produce the work, or an object code interpreter used to run it. | |
159 | ||
160 | The "Corresponding Source" for a work in object code form means all | |
161 | the source code needed to generate, install, and (for an executable | |
162 | work) run the object code and to modify the work, including scripts to | |
163 | control those activities. However, it does not include the work's | |
164 | System Libraries, or general-purpose tools or generally available free | |
165 | programs which are used unmodified in performing those activities but | |
166 | which are not part of the work. For example, Corresponding Source | |
167 | includes interface definition files associated with source files for | |
168 | the work, and the source code for shared libraries and dynamically | |
169 | linked subprograms that the work is specifically designed to require, | |
170 | such as by intimate data communication or control flow between those | |
171 | subprograms and other parts of the work. | |
172 | ||
173 | The Corresponding Source need not include anything that users | |
174 | can regenerate automatically from other parts of the Corresponding | |
175 | Source. | |
176 | ||
177 | The Corresponding Source for a work in source code form is that | |
178 | same work. | |
179 | ||
180 | 2. Basic Permissions. | |
181 | ||
182 | All rights granted under this License are granted for the term of | |
183 | copyright on the Program, and are irrevocable provided the stated | |
184 | conditions are met. This License explicitly affirms your unlimited | |
185 | permission to run the unmodified Program. The output from running a | |
186 | covered work is covered by this License only if the output, given its | |
187 | content, constitutes a covered work. This License acknowledges your | |
188 | rights of fair use or other equivalent, as provided by copyright law. | |
189 | ||
190 | You may make, run and propagate covered works that you do not | |
191 | convey, without conditions so long as your license otherwise remains | |
192 | in force. You may convey covered works to others for the sole purpose | |
193 | of having them make modifications exclusively for you, or provide you | |
194 | with facilities for running those works, provided that you comply with | |
195 | the terms of this License in conveying all material for which you do | |
196 | not control copyright. Those thus making or running the covered works | |
197 | for you must do so exclusively on your behalf, under your direction | |
198 | and control, on terms that prohibit them from making any copies of | |
199 | your copyrighted material outside their relationship with you. | |
200 | ||
201 | Conveying under any other circumstances is permitted solely under | |
202 | the conditions stated below. Sublicensing is not allowed; section 10 | |
203 | makes it unnecessary. | |
204 | ||
205 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. | |
206 | ||
207 | No covered work shall be deemed part of an effective technological | |
208 | measure under any applicable law fulfilling obligations under article | |
209 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or | |
210 | similar laws prohibiting or restricting circumvention of such | |
211 | measures. | |
212 | ||
213 | When you convey a covered work, you waive any legal power to forbid | |
214 | circumvention of technological measures to the extent such circumvention | |
215 | is effected by exercising rights under this License with respect to | |
216 | the covered work, and you disclaim any intention to limit operation or | |
217 | modification of the work as a means of enforcing, against the work's | |
218 | users, your or third parties' legal rights to forbid circumvention of | |
219 | technological measures. | |
220 | ||
221 | 4. Conveying Verbatim Copies. | |
222 | ||
223 | You may convey verbatim copies of the Program's source code as you | |
224 | receive it, in any medium, provided that you conspicuously and | |
225 | appropriately publish on each copy an appropriate copyright notice; | |
226 | keep intact all notices stating that this License and any | |
227 | non-permissive terms added in accord with section 7 apply to the code; | |
228 | keep intact all notices of the absence of any warranty; and give all | |
229 | recipients a copy of this License along with the Program. | |
230 | ||
231 | You may charge any price or no price for each copy that you convey, | |
232 | and you may offer support or warranty protection for a fee. | |
233 | ||
234 | 5. Conveying Modified Source Versions. | |
235 | ||
236 | You may convey a work based on the Program, or the modifications to | |
237 | produce it from the Program, in the form of source code under the | |
238 | terms of section 4, provided that you also meet all of these conditions: | |
239 | ||
240 | a) The work must carry prominent notices stating that you modified | |
241 | it, and giving a relevant date. | |
242 | ||
243 | b) The work must carry prominent notices stating that it is | |
244 | released under this License and any conditions added under section | |
245 | 7. This requirement modifies the requirement in section 4 to | |
246 | "keep intact all notices". | |
247 | ||
248 | c) You must license the entire work, as a whole, under this | |
249 | License to anyone who comes into possession of a copy. This | |
250 | License will therefore apply, along with any applicable section 7 | |
251 | additional terms, to the whole of the work, and all its parts, | |
252 | regardless of how they are packaged. This License gives no | |
253 | permission to license the work in any other way, but it does not | |
254 | invalidate such permission if you have separately received it. | |
255 | ||
256 | d) If the work has interactive user interfaces, each must display | |
257 | Appropriate Legal Notices; however, if the Program has interactive | |
258 | interfaces that do not display Appropriate Legal Notices, your | |
259 | work need not make them do so. | |
260 | ||
261 | A compilation of a covered work with other separate and independent | |
262 | works, which are not by their nature extensions of the covered work, | |
263 | and which are not combined with it such as to form a larger program, | |
264 | in or on a volume of a storage or distribution medium, is called an | |
265 | "aggregate" if the compilation and its resulting copyright are not | |
266 | used to limit the access or legal rights of the compilation's users | |
267 | beyond what the individual works permit. Inclusion of a covered work | |
268 | in an aggregate does not cause this License to apply to the other | |
269 | parts of the aggregate. | |
270 | ||
271 | 6. Conveying Non-Source Forms. | |
272 | ||
273 | You may convey a covered work in object code form under the terms | |
274 | of sections 4 and 5, provided that you also convey the | |
275 | machine-readable Corresponding Source under the terms of this License, | |
276 | in one of these ways: | |
277 | ||
278 | a) Convey the object code in, or embodied in, a physical product | |
279 | (including a physical distribution medium), accompanied by the | |
280 | Corresponding Source fixed on a durable physical medium | |
281 | customarily used for software interchange. | |
282 | ||
283 | b) Convey the object code in, or embodied in, a physical product | |
284 | (including a physical distribution medium), accompanied by a | |
285 | written offer, valid for at least three years and valid for as | |
286 | long as you offer spare parts or customer support for that product | |
287 | model, to give anyone who possesses the object code either (1) a | |
288 | copy of the Corresponding Source for all the software in the | |
289 | product that is covered by this License, on a durable physical | |
290 | medium customarily used for software interchange, for a price no | |
291 | more than your reasonable cost of physically performing this | |
292 | conveying of source, or (2) access to copy the | |
293 | Corresponding Source from a network server at no charge. | |
294 | ||
295 | c) Convey individual copies of the object code with a copy of the | |
296 | written offer to provide the Corresponding Source. This | |
297 | alternative is allowed only occasionally and noncommercially, and | |
298 | only if you received the object code with such an offer, in accord | |
299 | with subsection 6b. | |
300 | ||
301 | d) Convey the object code by offering access from a designated | |
302 | place (gratis or for a charge), and offer equivalent access to the | |
303 | Corresponding Source in the same way through the same place at no | |
304 | further charge. You need not require recipients to copy the | |
305 | Corresponding Source along with the object code. If the place to | |
306 | copy the object code is a network server, the Corresponding Source | |
307 | may be on a different server (operated by you or a third party) | |
308 | that supports equivalent copying facilities, provided you maintain | |
309 | clear directions next to the object code saying where to find the | |
310 | Corresponding Source. Regardless of what server hosts the | |
311 | Corresponding Source, you remain obligated to ensure that it is | |
312 | available for as long as needed to satisfy these requirements. | |
313 | ||
314 | e) Convey the object code using peer-to-peer transmission, provided | |
315 | you inform other peers where the object code and Corresponding | |
316 | Source of the work are being offered to the general public at no | |
317 | charge under subsection 6d. | |
318 | ||
319 | A separable portion of the object code, whose source code is excluded | |
320 | from the Corresponding Source as a System Library, need not be | |
321 | included in conveying the object code work. | |
322 | ||
323 | A "User Product" is either (1) a "consumer product", which means any | |
324 | tangible personal property which is normally used for personal, family, | |
325 | or household purposes, or (2) anything designed or sold for incorporation | |
326 | into a dwelling. In determining whether a product is a consumer product, | |
327 | doubtful cases shall be resolved in favor of coverage. For a particular | |
328 | product received by a particular user, "normally used" refers to a | |
329 | typical or common use of that class of product, regardless of the status | |
330 | of the particular user or of the way in which the particular user | |
331 | actually uses, or expects or is expected to use, the product. A product | |
332 | is a consumer product regardless of whether the product has substantial | |
333 | commercial, industrial or non-consumer uses, unless such uses represent | |
334 | the only significant mode of use of the product. | |
335 | ||
336 | "Installation Information" for a User Product means any methods, | |
337 | procedures, authorization keys, or other information required to install | |
338 | and execute modified versions of a covered work in that User Product from | |
339 | a modified version of its Corresponding Source. The information must | |
340 | suffice to ensure that the continued functioning of the modified object | |
341 | code is in no case prevented or interfered with solely because | |
342 | modification has been made. | |
343 | ||
344 | If you convey an object code work under this section in, or with, or | |
345 | specifically for use in, a User Product, and the conveying occurs as | |
346 | part of a transaction in which the right of possession and use of the | |
347 | User Product is transferred to the recipient in perpetuity or for a | |
348 | fixed term (regardless of how the transaction is characterized), the | |
349 | Corresponding Source conveyed under this section must be accompanied | |
350 | by the Installation Information. But this requirement does not apply | |
351 | if neither you nor any third party retains the ability to install | |
352 | modified object code on the User Product (for example, the work has | |
353 | been installed in ROM). | |
354 | ||
355 | The requirement to provide Installation Information does not include a | |
356 | requirement to continue to provide support service, warranty, or updates | |
357 | for a work that has been modified or installed by the recipient, or for | |
358 | the User Product in which it has been modified or installed. Access to a | |
359 | network may be denied when the modification itself materially and | |
360 | adversely affects the operation of the network or violates the rules and | |
361 | protocols for communication across the network. | |
362 | ||
363 | Corresponding Source conveyed, and Installation Information provided, | |
364 | in accord with this section must be in a format that is publicly | |
365 | documented (and with an implementation available to the public in | |
366 | source code form), and must require no special password or key for | |
367 | unpacking, reading or copying. | |
368 | ||
369 | 7. Additional Terms. | |
370 | ||
371 | "Additional permissions" are terms that supplement the terms of this | |
372 | License by making exceptions from one or more of its conditions. | |
373 | Additional permissions that are applicable to the entire Program shall | |
374 | be treated as though they were included in this License, to the extent | |
375 | that they are valid under applicable law. If additional permissions | |
376 | apply only to part of the Program, that part may be used separately | |
377 | under those permissions, but the entire Program remains governed by | |
378 | this License without regard to the additional permissions. | |
379 | ||
380 | When you convey a copy of a covered work, you may at your option | |
381 | remove any additional permissions from that copy, or from any part of | |
382 | it. (Additional permissions may be written to require their own | |
383 | removal in certain cases when you modify the work.) You may place | |
384 | additional permissions on material, added by you to a covered work, | |
385 | for which you have or can give appropriate copyright permission. | |
386 | ||
387 | Notwithstanding any other provision of this License, for material you | |
388 | add to a covered work, you may (if authorized by the copyright holders of | |
389 | that material) supplement the terms of this License with terms: | |
390 | ||
391 | a) Disclaiming warranty or limiting liability differently from the | |
392 | terms of sections 15 and 16 of this License; or | |
393 | ||
394 | b) Requiring preservation of specified reasonable legal notices or | |
395 | author attributions in that material or in the Appropriate Legal | |
396 | Notices displayed by works containing it; or | |
397 | ||
398 | c) Prohibiting misrepresentation of the origin of that material, or | |
399 | requiring that modified versions of such material be marked in | |
400 | reasonable ways as different from the original version; or | |
401 | ||
402 | d) Limiting the use for publicity purposes of names of licensors or | |
403 | authors of the material; or | |
404 | ||
405 | e) Declining to grant rights under trademark law for use of some | |
406 | trade names, trademarks, or service marks; or | |
407 | ||
408 | f) Requiring indemnification of licensors and authors of that | |
409 | material by anyone who conveys the material (or modified versions of | |
410 | it) with contractual assumptions of liability to the recipient, for | |
411 | any liability that these contractual assumptions directly impose on | |
412 | those licensors and authors. | |
413 | ||
414 | All other non-permissive additional terms are considered "further | |
415 | restrictions" within the meaning of section 10. If the Program as you | |
416 | received it, or any part of it, contains a notice stating that it is | |
417 | governed by this License along with a term that is a further restriction, | |
418 | you may remove that term. If a license document contains a further | |
419 | restriction but permits relicensing or conveying under this License, you | |
420 | may add to a covered work material governed by the terms of that license | |
421 | document, provided that the further restriction does not survive such | |
422 | relicensing or conveying. | |
423 | ||
424 | If you add terms to a covered work in accord with this section, you | |
425 | must place, in the relevant source files, a statement of the | |
426 | additional terms that apply to those files, or a notice indicating | |
427 | where to find the applicable terms. | |
428 | ||
429 | Additional terms, permissive or non-permissive, may be stated in the | |
430 | form of a separately written license, or stated as exceptions; | |
431 | the above requirements apply either way. | |
432 | ||
433 | 8. Termination. | |
434 | ||
435 | You may not propagate or modify a covered work except as expressly | |
436 | provided under this License. Any attempt otherwise to propagate or | |
437 | modify it is void, and will automatically terminate your rights under | |
438 | this License (including any patent licenses granted under the third | |
439 | paragraph of section 11). | |
440 | ||
441 | However, if you cease all violation of this License, then your | |
442 | license from a particular copyright holder is reinstated (a) | |
443 | provisionally, unless and until the copyright holder explicitly and | |
444 | finally terminates your license, and (b) permanently, if the copyright | |
445 | holder fails to notify you of the violation by some reasonable means | |
446 | prior to 60 days after the cessation. | |
447 | ||
448 | Moreover, your license from a particular copyright holder is | |
449 | reinstated permanently if the copyright holder notifies you of the | |
450 | violation by some reasonable means, this is the first time you have | |
451 | received notice of violation of this License (for any work) from that | |
452 | copyright holder, and you cure the violation prior to 30 days after | |
453 | your receipt of the notice. | |
454 | ||
455 | Termination of your rights under this section does not terminate the | |
456 | licenses of parties who have received copies or rights from you under | |
457 | this License. If your rights have been terminated and not permanently | |
458 | reinstated, you do not qualify to receive new licenses for the same | |
459 | material under section 10. | |
460 | ||
461 | 9. Acceptance Not Required for Having Copies. | |
462 | ||
463 | You are not required to accept this License in order to receive or | |
464 | run a copy of the Program. Ancillary propagation of a covered work | |
465 | occurring solely as a consequence of using peer-to-peer transmission | |
466 | to receive a copy likewise does not require acceptance. However, | |
467 | nothing other than this License grants you permission to propagate or | |
468 | modify any covered work. These actions infringe copyright if you do | |
469 | not accept this License. Therefore, by modifying or propagating a | |
470 | covered work, you indicate your acceptance of this License to do so. | |
471 | ||
472 | 10. Automatic Licensing of Downstream Recipients. | |
473 | ||
474 | Each time you convey a covered work, the recipient automatically | |
475 | receives a license from the original licensors, to run, modify and | |
476 | propagate that work, subject to this License. You are not responsible | |
477 | for enforcing compliance by third parties with this License. | |
478 | ||
479 | An "entity transaction" is a transaction transferring control of an | |
480 | organization, or substantially all assets of one, or subdividing an | |
481 | organization, or merging organizations. If propagation of a covered | |
482 | work results from an entity transaction, each party to that | |
483 | transaction who receives a copy of the work also receives whatever | |
484 | licenses to the work the party's predecessor in interest had or could | |
485 | give under the previous paragraph, plus a right to possession of the | |
486 | Corresponding Source of the work from the predecessor in interest, if | |
487 | the predecessor has it or can get it with reasonable efforts. | |
488 | ||
489 | You may not impose any further restrictions on the exercise of the | |
490 | rights granted or affirmed under this License. For example, you may | |
491 | not impose a license fee, royalty, or other charge for exercise of | |
492 | rights granted under this License, and you may not initiate litigation | |
493 | (including a cross-claim or counterclaim in a lawsuit) alleging that | |
494 | any patent claim is infringed by making, using, selling, offering for | |
495 | sale, or importing the Program or any portion of it. | |
496 | ||
497 | 11. Patents. | |
498 | ||
499 | A "contributor" is a copyright holder who authorizes use under this | |
500 | License of the Program or a work on which the Program is based. The | |
501 | work thus licensed is called the contributor's "contributor version". | |
502 | ||
503 | A contributor's "essential patent claims" are all patent claims | |
504 | owned or controlled by the contributor, whether already acquired or | |
505 | hereafter acquired, that would be infringed by some manner, permitted | |
506 | by this License, of making, using, or selling its contributor version, | |
507 | but do not include claims that would be infringed only as a | |
508 | consequence of further modification of the contributor version. For | |
509 | purposes of this definition, "control" includes the right to grant | |
510 | patent sublicenses in a manner consistent with the requirements of | |
511 | this License. | |
512 | ||
513 | Each contributor grants you a non-exclusive, worldwide, royalty-free | |
514 | patent license under the contributor's essential patent claims, to | |
515 | make, use, sell, offer for sale, import and otherwise run, modify and | |
516 | propagate the contents of its contributor version. | |
517 | ||
518 | In the following three paragraphs, a "patent license" is any express | |
519 | agreement or commitment, however denominated, not to enforce a patent | |
520 | (such as an express permission to practice a patent or covenant not to | |
521 | sue for patent infringement). To "grant" such a patent license to a | |
522 | party means to make such an agreement or commitment not to enforce a | |
523 | patent against the party. | |
524 | ||
525 | If you convey a covered work, knowingly relying on a patent license, | |
526 | and the Corresponding Source of the work is not available for anyone | |
527 | to copy, free of charge and under the terms of this License, through a | |
528 | publicly available network server or other readily accessible means, | |
529 | then you must either (1) cause the Corresponding Source to be so | |
530 | available, or (2) arrange to deprive yourself of the benefit of the | |
531 | patent license for this particular work, or (3) arrange, in a manner | |
532 | consistent with the requirements of this License, to extend the patent | |
533 | license to downstream recipients. "Knowingly relying" means you have | |
534 | actual knowledge that, but for the patent license, your conveying the | |
535 | covered work in a country, or your recipient's use of the covered work | |
536 | in a country, would infringe one or more identifiable patents in that | |
537 | country that you have reason to believe are valid. | |
538 | ||
539 | If, pursuant to or in connection with a single transaction or | |
540 | arrangement, you convey, or propagate by procuring conveyance of, a | |
541 | covered work, and grant a patent license to some of the parties | |
542 | receiving the covered work authorizing them to use, propagate, modify | |
543 | or convey a specific copy of the covered work, then the patent license | |
544 | you grant is automatically extended to all recipients of the covered | |
545 | work and works based on it. | |
546 | ||
547 | A patent license is "discriminatory" if it does not include within | |
548 | the scope of its coverage, prohibits the exercise of, or is | |
549 | conditioned on the non-exercise of one or more of the rights that are | |
550 | specifically granted under this License. You may not convey a covered | |
551 | work if you are a party to an arrangement with a third party that is | |
552 | in the business of distributing software, under which you make payment | |
553 | to the third party based on the extent of your activity of conveying | |
554 | the work, and under which the third party grants, to any of the | |
555 | parties who would receive the covered work from you, a discriminatory | |
556 | patent license (a) in connection with copies of the covered work | |
557 | conveyed by you (or copies made from those copies), or (b) primarily | |
558 | for and in connection with specific products or compilations that | |
559 | contain the covered work, unless you entered into that arrangement, | |
560 | or that patent license was granted, prior to 28 March 2007. | |
561 | ||
562 | Nothing in this License shall be construed as excluding or limiting | |
563 | any implied license or other defenses to infringement that may | |
564 | otherwise be available to you under applicable patent law. | |
565 | ||
566 | 12. No Surrender of Others' Freedom. | |
567 | ||
568 | If conditions are imposed on you (whether by court order, agreement or | |
569 | otherwise) that contradict the conditions of this License, they do not | |
570 | excuse you from the conditions of this License. If you cannot convey a | |
571 | covered work so as to satisfy simultaneously your obligations under this | |
572 | License and any other pertinent obligations, then as a consequence you may | |
573 | not convey it at all. For example, if you agree to terms that obligate you | |
574 | to collect a royalty for further conveying from those to whom you convey | |
575 | the Program, the only way you could satisfy both those terms and this | |
576 | License would be to refrain entirely from conveying the Program. | |
577 | ||
578 | 13. Remote Network Interaction; Use with the GNU General Public License. | |
579 | ||
580 | Notwithstanding any other provision of this License, if you modify the | |
581 | Program, your modified version must prominently offer all users | |
582 | interacting with it remotely through a computer network (if your version | |
583 | supports such interaction) an opportunity to receive the Corresponding | |
584 | Source of your version by providing access to the Corresponding Source | |
585 | from a network server at no charge, through some standard or customary | |
586 | means of facilitating copying of software. This Corresponding Source | |
587 | shall include the Corresponding Source for any work covered by version 3 | |
588 | of the GNU General Public License that is incorporated pursuant to the | |
589 | following paragraph. | |
590 | ||
591 | Notwithstanding any other provision of this License, you have permission | |
592 | to link or combine any covered work with a work licensed under version 3 | |
593 | of the GNU General Public License into a single combined work, and to | |
594 | convey the resulting work. The terms of this License will continue to | |
595 | apply to the part which is the covered work, but the work with which it is | |
596 | combined will remain governed by version 3 of the GNU General Public | |
597 | License. | |
598 | ||
599 | 14. Revised Versions of this License. | |
600 | ||
601 | The Free Software Foundation may publish revised and/or new versions of | |
602 | the GNU Affero General Public License from time to time. Such new | |
603 | versions will be similar in spirit to the present version, but may differ | |
604 | in detail to address new problems or concerns. | |
605 | ||
606 | Each version is given a distinguishing version number. If the | |
607 | Program specifies that a certain numbered version of the GNU Affero | |
608 | General Public License "or any later version" applies to it, you have | |
609 | the option of following the terms and conditions either of that | |
610 | numbered version or of any later version published by the Free | |
611 | Software Foundation. If the Program does not specify a version number | |
612 | of the GNU Affero General Public License, you may choose any version | |
613 | ever published by the Free Software Foundation. | |
614 | ||
615 | If the Program specifies that a proxy can decide which future | |
616 | versions of the GNU Affero General Public License can be used, that | |
617 | proxy's public statement of acceptance of a version permanently | |
618 | authorizes you to choose that version for the Program. | |
619 | ||
620 | Later license versions may give you additional or different | |
621 | permissions. However, no additional obligations are imposed on any | |
622 | author or copyright holder as a result of your choosing to follow a | |
623 | later version. | |
624 | ||
625 | 15. Disclaimer of Warranty. | |
626 | ||
627 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY | |
628 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT | |
629 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY | |
630 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, | |
631 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR | |
632 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM | |
633 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF | |
634 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. | |
635 | ||
636 | 16. Limitation of Liability. | |
637 | ||
638 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
639 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS | |
640 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY | |
641 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE | |
642 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF | |
643 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD | |
644 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), | |
645 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF | |
646 | SUCH DAMAGES. | |
647 | ||
648 | 17. Interpretation of Sections 15 and 16. | |
649 | ||
650 | If the disclaimer of warranty and limitation of liability provided | |
651 | above cannot be given local legal effect according to their terms, | |
652 | reviewing courts shall apply local law that most closely approximates | |
653 | an absolute waiver of all civil liability in connection with the | |
654 | Program, unless a warranty or assumption of liability accompanies a | |
655 | copy of the Program in return for a fee. | |
656 | ||
657 | END OF TERMS AND CONDITIONS | |
658 | ||
659 | How to Apply These Terms to Your New Programs | |
660 | ||
661 | If you develop a new program, and you want it to be of the greatest | |
662 | possible use to the public, the best way to achieve this is to make it | |
663 | free software which everyone can redistribute and change under these terms. | |
664 | ||
665 | To do so, attach the following notices to the program. It is safest | |
666 | to attach them to the start of each source file to most effectively | |
667 | state the exclusion of warranty; and each file should have at least | |
668 | the "copyright" line and a pointer to where the full notice is found. | |
669 | ||
670 | <one line to give the program's name and a brief idea of what it does.> | |
671 | Copyright (C) <year> <name of author> | |
672 | ||
673 | This program is free software: you can redistribute it and/or modify | |
674 | it under the terms of the GNU Affero General Public License as | |
675 | published by the Free Software Foundation, either version 3 of the | |
676 | License, or (at your option) any later version. | |
677 | ||
678 | This program is distributed in the hope that it will be useful, | |
679 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |
680 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | |
681 | GNU Affero General Public License for more details. | |
682 | ||
683 | You should have received a copy of the GNU Affero General Public License | |
684 | along with this program. If not, see <http://www.gnu.org/licenses/>. | |
685 | ||
686 | Also add information on how to contact you by electronic and paper mail. | |
687 | ||
688 | If your software can interact with users remotely through a computer | |
689 | network, you should also make sure that it provides a way for users to | |
690 | get its source. For example, if your program is a web application, its | |
691 | interface could display a "Source" link that leads users to an archive | |
692 | of the code. There are many ways you could offer source, and different | |
693 | solutions will be better for different programs; see section 13 for the | |
694 | specific requirements. | |
695 | ||
696 | You should also get your employer (if you work as a programmer) or school, | |
697 | if any, to sign a "copyright disclaimer" for the program, if necessary. | |
