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