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