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