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