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