  4. (at your option) any later version.
  5. This program is distributed in the hope that it will be useful,

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