  4. @c hence no sectioning command or @node.
  5. @display
  6. Copyright @copyright{} 2007 Free Software Foundation, Inc. @url{http://fsf.org/}

  10. @heading Preamble
  11. The GNU General Public License is a free, copyleft license for
  12. software and other kinds of works.
  13. The licenses for most software and other practical works are designed
  14. to take away your freedom to share and change the works. By contrast,
  15. the GNU General Public License is intended to guarantee your freedom
  16. to share and change all versions of a program---to make sure it remains
  17. free software for all its users. We, the Free Software Foundation,
  18. use the GNU General Public License for most of our software; it
  19. applies also to any other work released this way by its authors. You
  20. can apply it to your programs, too.
  21. When we speak of free software, we are referring to freedom, not
  22. price. Our General Public Licenses are designed to make sure that you
  23. have the freedom to distribute copies of free software (and charge for
  24. them if you wish), that you receive source code or can get it if you
  25. want it, that you can change the software or use pieces of it in new
  26. free programs, and that you know you can do these things.
  27. To protect your rights, we need to prevent others from denying you
  28. these rights or asking you to surrender the rights. Therefore, you
  29. have certain responsibilities if you distribute copies of the
  30. software, or if you modify it: responsibilities to respect the freedom
  31. of others.
  32. For example, if you distribute copies of such a program, whether
  33. gratis or for a fee, you must pass on to the recipients the same
  34. freedoms that you received. You must make sure that they, too,
  35. receive or can get the source code. And you must show them these
  36. terms so they know their rights.
  37. Developers that use the GNU GPL protect your rights with two steps:
  38. (1) assert copyright on the software, and (2) offer you this License
  39. giving you legal permission to copy, distribute and/or modify it.
  40. For the developers' and authors' protection, the GPL clearly explains
  41. that there is no warranty for this free software. For both users' and
  42. authors' sake, the GPL requires that modified versions be marked as
  43. changed, so that their problems will not be attributed erroneously to
  44. authors of previous versions.
  45. Some devices are designed to deny users access to install or run
  46. modified versions of the software inside them, although the
  47. manufacturer can do so. This is fundamentally incompatible with the
  48. aim of protecting users' freedom to change the software. The
  49. systematic pattern of such abuse occurs in the area of products for
  50. individuals to use, which is precisely where it is most unacceptable.
  51. Therefore, we have designed this version of the GPL to prohibit the
  52. practice for those products. If such problems arise substantially in
  53. other domains, we stand ready to extend this provision to those
  54. domains in future versions of the GPL, as needed to protect the
  55. freedom of users.
  56. Finally, every program is threatened constantly by software patents.
  57. States should not allow patents to restrict development and use of
  58. software on general-purpose computers, but in those that do, we wish
  59. to avoid the special danger that patents applied to a free program
  60. could make it effectively proprietary. To prevent this, the GPL
  61. assures that patents cannot be used to render the program non-free.
  62. The precise terms and conditions for copying, distribution and
  63. modification follow.
  64. @heading TERMS AND CONDITIONS
  65. @enumerate 0
  66. @item Definitions.
  67. ``This License'' refers to version 3 of the GNU General Public License.
  68. ``Copyright'' also means copyright-like laws that apply to other kinds
  69. of works, such as semiconductor masks.
  70. ``The Program'' refers to any copyrightable work licensed under this
  71. License. Each licensee is addressed as ``you''. ``Licensees'' and
  72. ``recipients'' may be individuals or organizations.
  73. To ``modify'' a work means to copy from or adapt all or part of the work
  74. in a fashion requiring copyright permission, other than the making of
  75. an exact copy. The resulting work is called a ``modified version'' of
  76. the earlier work or a work ``based on'' the earlier work.
  77. A ``covered work'' means either the unmodified Program or a work based
  78. on the Program.
  79. To ``propagate'' a work means to do anything with it that, without
  80. permission, would make you directly or secondarily liable for
  81. infringement under applicable copyright law, except executing it on a
  82. computer or modifying a private copy. Propagation includes copying,
  83. distribution (with or without modification), making available to the
  84. public, and in some countries other activities as well.
  85. To ``convey'' a work means any kind of propagation that enables other
  86. parties to make or receive copies. Mere interaction with a user
  87. through a computer network, with no transfer of a copy, is not
  88. conveying.
  89. An interactive user interface displays ``Appropriate Legal Notices'' to
  90. 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. @item Source Code.
  98. The ``source code'' for a work means the preferred form of the work for
  99. making modifications to it. ``Object code'' means any non-source form
  100. 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 can
  128. regenerate automatically from other parts of the Corresponding Source.
  129. The Corresponding Source for a work in source code form is that same
  130. work.
  131. @item Basic Permissions.
  132. All rights granted under this License are granted for the term of
  133. copyright on the Program, and are irrevocable provided the stated
  134. conditions are met. This License explicitly affirms your unlimited
  135. permission to run the unmodified Program. The output from running a
  136. covered work is covered by this License only if the output, given its
  137. content, constitutes a covered work. This License acknowledges your
  138. rights of fair use or other equivalent, as provided by copyright law.
  139. You may make, run and propagate covered works that you do not convey,
  140. without conditions so long as your license otherwise remains in force.
  141. You may convey covered works to others for the sole purpose of having
  142. them make modifications exclusively for you, or provide you with
  143. facilities for running those works, provided that you comply with the
  144. terms of this License in conveying all material for which you do not
  145. control copyright. Those thus making or running the covered works for
  146. you must do so exclusively on your behalf, under your direction and
  147. control, on terms that prohibit them from making any copies of your
  148. copyrighted material outside their relationship with you.
  149. Conveying under any other circumstances is permitted solely under the
  150. conditions stated below. Sublicensing is not allowed; section 10
  151. makes it unnecessary.
  152. @item Protecting Users' Legal Rights From Anti-Circumvention Law.
  153. No covered work shall be deemed part of an effective technological
  154. measure under any applicable law fulfilling obligations under article
  155. 11 of the WIPO copyright treaty adopted on 20 December 1996, or
  156. similar laws prohibiting or restricting circumvention of such
  157. measures.
  158. When you convey a covered work, you waive any legal power to forbid
  159. circumvention of technological measures to the extent such
  160. circumvention is effected by exercising rights under this License with
  161. respect to the covered work, and you disclaim any intention to limit
  162. operation or modification of the work as a means of enforcing, against
  163. the work's users, your or third parties' legal rights to forbid
  164. circumvention of technological measures.
  165. @item Conveying Verbatim Copies.
  166. You may convey verbatim copies of the Program's source code as you
  167. receive it, in any medium, provided that you conspicuously and
  168. appropriately publish on each copy an appropriate copyright notice;
  169. keep intact all notices stating that this License and any
  170. non-permissive terms added in accord with section 7 apply to the code;
  171. keep intact all notices of the absence of any warranty; and give all
  172. recipients a copy of this License along with the Program.
  173. You may charge any price or no price for each copy that you convey,
  174. and you may offer support or warranty protection for a fee.
  175. @item Conveying Modified Source Versions.
  176. You may convey a work based on the Program, or the modifications to
  177. produce it from the Program, in the form of source code under the
  178. terms of section 4, provided that you also meet all of these
  179. conditions:
  180. @enumerate a
  181. @item
  182. The work must carry prominent notices stating that you modified it,
  183. and giving a relevant date.
  184. @item
  185. The work must carry prominent notices stating that it is released
  186. under this License and any conditions added under section 7. This
  187. requirement modifies the requirement in section 4 to ``keep intact all
  188. notices''.
  189. @item
  190. You must license the entire work, as a whole, under this License to
  191. anyone who comes into possession of a copy. This License will
  192. therefore apply, along with any applicable section 7 additional terms,
  193. to the whole of the work, and all its parts, regardless of how they
  194. are packaged. This License gives no permission to license the work in
  195. any other way, but it does not invalidate such permission if you have
  196. separately received it.
  197. @item
  198. If the work has interactive user interfaces, each must display
  199. Appropriate Legal Notices; however, if the Program has interactive
  200. interfaces that do not display Appropriate Legal Notices, your work
  201. need not make them do so.
  202. @end enumerate
  203. A compilation of a covered work with other separate and independent
  204. works, which are not by their nature extensions of the covered work,
  205. and which are not combined with it such as to form a larger program,
  206. in or on a volume of a storage or distribution medium, is called an
  207. ``aggregate'' if the compilation and its resulting copyright are not
  208. used to limit the access or legal rights of the compilation's users
  209. beyond what the individual works permit. Inclusion of a covered work
  210. in an aggregate does not cause this License to apply to the other
  211. parts of the aggregate.
  212. @item Conveying Non-Source Forms.
  213. You may convey a covered work in object code form under the terms of
  214. sections 4 and 5, provided that you also convey the machine-readable
  215. Corresponding Source under the terms of this License, in one of these
  216. ways:
  217. @enumerate a
  218. @item
  219. Convey the object code in, or embodied in, a physical product
  220. (including a physical distribution medium), accompanied by the
  221. Corresponding Source fixed on a durable physical medium customarily
  222. used for software interchange.
  223. @item
  224. Convey the object code in, or embodied in, a physical product
  225. (including a physical distribution medium), accompanied by a written
  226. offer, valid for at least three years and valid for as long as you
  227. offer spare parts or customer support for that product model, to give
  228. anyone who possesses the object code either (1) a copy of the
  229. Corresponding Source for all the software in the product that is
  230. covered by this License, on a durable physical medium customarily used
  231. for software interchange, for a price no more than your reasonable
  232. cost of physically performing this conveying of source, or (2) access
  233. to copy the Corresponding Source from a network server at no charge.
  234. @item
  235. Convey individual copies of the object code with a copy of the written
  236. offer to provide the Corresponding Source. This alternative is
  237. allowed only occasionally and noncommercially, and only if you
  238. received the object code with such an offer, in accord with subsection
  239. 6b.
  240. @item
  241. Convey the object code by offering access from a designated place
  242. (gratis or for a charge), and offer equivalent access to the
  243. Corresponding Source in the same way through the same place at no
  244. further charge. You need not require recipients to copy the
  245. Corresponding Source along with the object code. If the place to copy
  246. the object code is a network server, the Corresponding Source may be
  247. on a different server (operated by you or a third party) that supports
  248. equivalent copying facilities, provided you maintain clear directions
  249. next to the object code saying where to find the Corresponding Source.
  250. Regardless of what server hosts the Corresponding Source, you remain
  251. obligated to ensure that it is available for as long as needed to
  252. satisfy these requirements.
  253. @item
  254. Convey the object code using peer-to-peer transmission, provided you
  255. inform other peers where the object code and Corresponding Source of
  256. the work are being offered to the general public at no charge under
  257. subsection 6d.
  258. @end enumerate
  259. A separable portion of the object code, whose source code is excluded
  260. from the Corresponding Source as a System Library, need not be
  261. included in conveying the object code work.
  262. A ``User Product'' is either (1) a ``consumer product'', which means any
  263. tangible personal property which is normally used for personal,
  264. family, or household purposes, or (2) anything designed or sold for
  265. incorporation into a dwelling. In determining whether a product is a
  266. consumer product, doubtful cases shall be resolved in favor of
  267. coverage. For a particular product received by a particular user,
  268. ``normally used'' refers to a typical or common use of that class of
  269. product, regardless of the status of the particular user or of the way
  270. in which the particular user actually uses, or expects or is expected
  271. to use, the product. A product is a consumer product regardless of
  272. whether the product has substantial commercial, industrial or
  273. non-consumer uses, unless such uses represent the only significant
  274. mode of use of the product.
  275. ``Installation Information'' for a User Product means any methods,
  276. procedures, authorization keys, or other information required to
  277. install and execute modified versions of a covered work in that User
  278. Product from a modified version of its Corresponding Source. The
  279. information must suffice to ensure that the continued functioning of
  280. the modified object code is in no case prevented or interfered with
  281. solely because modification has been made.
  282. If you convey an object code work under this section in, or with, or
  283. specifically for use in, a User Product, and the conveying occurs as
  284. part of a transaction in which the right of possession and use of the
  285. User Product is transferred to the recipient in perpetuity or for a
  286. fixed term (regardless of how the transaction is characterized), the
  287. Corresponding Source conveyed under this section must be accompanied
  288. by the Installation Information. But this requirement does not apply
  289. if neither you nor any third party retains the ability to install
  290. modified object code on the User Product (for example, the work has
  291. been installed in ROM).
  292. The requirement to provide Installation Information does not include a
  293. requirement to continue to provide support service, warranty, or
  294. updates for a work that has been modified or installed by the
  295. recipient, or for the User Product in which it has been modified or
  296. installed. Access to a network may be denied when the modification
  297. itself materially and adversely affects the operation of the network
  298. or violates the rules and protocols for communication across the
  299. network.
  300. Corresponding Source conveyed, and Installation Information provided,
  301. in accord with this section must be in a format that is publicly
  302. documented (and with an implementation available to the public in
  303. source code form), and must require no special password or key for
  304. unpacking, reading or copying.
  305. @item Additional Terms.
  306. ``Additional permissions'' are terms that supplement the terms of this
  307. License by making exceptions from one or more of its conditions.
  308. Additional permissions that are applicable to the entire Program shall
  309. be treated as though they were included in this License, to the extent
  310. that they are valid under applicable law. If additional permissions
  311. apply only to part of the Program, that part may be used separately
  312. under those permissions, but the entire Program remains governed by
  313. this License without regard to the additional permissions.
  314. When you convey a copy of a covered work, you may at your option
  315. remove any additional permissions from that copy, or from any part of
  316. it. (Additional permissions may be written to require their own
  317. removal in certain cases when you modify the work.) You may place
  318. additional permissions on material, added by you to a covered work,
  319. for which you have or can give appropriate copyright permission.
  320. Notwithstanding any other provision of this License, for material you
  321. add to a covered work, you may (if authorized by the copyright holders
  322. of that material) supplement the terms of this License with terms:

  346. licensors and authors.
  347. @end enumerate
  348. All other non-permissive additional terms are considered ``further
  349. restrictions'' within the meaning of section 10. If the Program as you
  350. received it, or any part of it, contains a notice stating that it is
  351. governed by this License along with a term that is a further
  352. restriction, you may remove that term. If a license document contains
  353. a further restriction but permits relicensing or conveying under this
  354. License, you may add to a covered work material governed by the terms
  355. of that license document, provided that the further restriction does
  356. not survive such relicensing or conveying.
  357. If you add terms to a covered work in accord with this section, you
  358. must place, in the relevant source files, a statement of the
  359. additional terms that apply to those files, or a notice indicating
  360. where to find the applicable terms.
  361. Additional terms, permissive or non-permissive, may be stated in the
  362. form of a separately written license, or stated as exceptions; the
  363. above requirements apply either way.
  364. @item Termination.
  365. You may not propagate or modify a covered work except as expressly
  366. provided under this License. Any attempt otherwise to propagate or
  367. modify it is void, and will automatically terminate your rights under
  368. this License (including any patent licenses granted under the third
  369. paragraph of section 11).
  370. However, if you cease all violation of this License, then your license
  371. from a particular copyright holder is reinstated (a) provisionally,
  372. unless and until the copyright holder explicitly and finally
  373. terminates your license, and (b) permanently, if the copyright holder
  374. fails to notify you of the violation by some reasonable means prior to
  375. 60 days after the cessation.
  376. Moreover, your license from a particular copyright holder is
  377. reinstated permanently if the copyright holder notifies you of the
  378. violation by some reasonable means, this is the first time you have
  379. received notice of violation of this License (for any work) from that
  380. copyright holder, and you cure the violation prior to 30 days after
  381. your receipt of the notice.
  382. Termination of your rights under this section does not terminate the
  383. licenses of parties who have received copies or rights from you under
  384. this License. If your rights have been terminated and not permanently
  385. reinstated, you do not qualify to receive new licenses for the same
  386. material under section 10.
  387. @item Acceptance Not Required for Having Copies.
  388. You are not required to accept this License in order to receive or run
  389. a copy of the Program. Ancillary propagation of a covered work
  390. occurring solely as a consequence of using peer-to-peer transmission
  391. to receive a copy likewise does not require acceptance. However,
  392. nothing other than this License grants you permission to propagate or
  393. modify any covered work. These actions infringe copyright if you do
  394. not accept this License. Therefore, by modifying or propagating a
  395. covered work, you indicate your acceptance of this License to do so.
  396. @item Automatic Licensing of Downstream Recipients.
  397. Each time you convey a covered work, the recipient automatically
  398. receives a license from the original licensors, to run, modify and
  399. propagate that work, subject to this License. You are not responsible
  400. for enforcing compliance by third parties with this License.
  401. An ``entity transaction'' is a transaction transferring control of an
  402. organization, or substantially all assets of one, or subdividing an
  403. organization, or merging organizations. If propagation of a covered
  404. work results from an entity transaction, each party to that
  405. transaction who receives a copy of the work also receives whatever
  406. licenses to the work the party's predecessor in interest had or could
  407. give under the previous paragraph, plus a right to possession of the
  408. Corresponding Source of the work from the predecessor in interest, if
  409. the predecessor has it or can get it with reasonable efforts.
  410. You may not impose any further restrictions on the exercise of the
  411. rights granted or affirmed under this License. For example, you may
  412. not impose a license fee, royalty, or other charge for exercise of
  413. rights granted under this License, and you may not initiate litigation
  414. (including a cross-claim or counterclaim in a lawsuit) alleging that
  415. any patent claim is infringed by making, using, selling, offering for
  416. sale, or importing the Program or any portion of it.
  417. @item Patents.
  418. A ``contributor'' is a copyright holder who authorizes use under this
  419. License of the Program or a work on which the Program is based. The
  420. work thus licensed is called the contributor's ``contributor version''.
  421. A contributor's ``essential patent claims'' are all patent claims owned
  422. or controlled by the contributor, whether already acquired or
  423. hereafter acquired, that would be infringed by some manner, permitted
  424. by this License, of making, using, or selling its contributor version,
  425. but do not include claims that would be infringed only as a
  426. consequence of further modification of the contributor version. For
  427. purposes of this definition, ``control'' includes the right to grant
  428. patent sublicenses in a manner consistent with the requirements of
  429. this License.
  430. Each contributor grants you a non-exclusive, worldwide, royalty-free
  431. patent license under the contributor's essential patent claims, to
  432. make, use, sell, offer for sale, import and otherwise run, modify and
  433. propagate the contents of its contributor version.
  434. In the following three paragraphs, a ``patent license'' is any express
  435. agreement or commitment, however denominated, not to enforce a patent
  436. (such as an express permission to practice a patent or covenant not to
  437. sue for patent infringement). To ``grant'' such a patent license to a
  438. party means to make such an agreement or commitment not to enforce a
  439. patent against the party.
  440. If you convey a covered work, knowingly relying on a patent license,
  441. and the Corresponding Source of the work is not available for anyone
  442. to copy, free of charge and under the terms of this License, through a
  443. publicly available network server or other readily accessible means,
  444. then you must either (1) cause the Corresponding Source to be so
  445. available, or (2) arrange to deprive yourself of the benefit of the
  446. patent license for this particular work, or (3) arrange, in a manner
  447. consistent with the requirements of this License, to extend the patent
  448. license to downstream recipients. ``Knowingly relying'' means you have
  449. actual knowledge that, but for the patent license, your conveying the
  450. covered work in a country, or your recipient's use of the covered work
  451. in a country, would infringe one or more identifiable patents in that
  452. country that you have reason to believe are valid.
  453. If, pursuant to or in connection with a single transaction or
  454. arrangement, you convey, or propagate by procuring conveyance of, a
  455. covered work, and grant a patent license to some of the parties
  456. receiving the covered work authorizing them to use, propagate, modify
  457. or convey a specific copy of the covered work, then the patent license
  458. you grant is automatically extended to all recipients of the covered
  459. work and works based on it.
  460. A patent license is ``discriminatory'' if it does not include within the
  461. scope of its coverage, prohibits the exercise of, or is conditioned on
  462. the non-exercise of one or more of the rights that are specifically
  463. granted under this License. You may not convey a covered work if you
  464. are a party to an arrangement with a third party that is in the
  465. business of distributing software, under which you make payment to the
  466. third party based on the extent of your activity of conveying the
  467. work, and under which the third party grants, to any of the parties
  468. who would receive the covered work from you, a discriminatory patent
  469. license (a) in connection with copies of the covered work conveyed by
  470. you (or copies made from those copies), or (b) primarily for and in
  471. connection with specific products or compilations that contain the
  472. covered work, unless you entered into that arrangement, or that patent
  473. license was granted, prior to 28 March 2007.
  474. Nothing in this License shall be construed as excluding or limiting
  475. any implied license or other defenses to infringement that may
  476. otherwise be available to you under applicable patent law.
  477. @item No Surrender of Others' Freedom.
  478. If conditions are imposed on you (whether by court order, agreement or
  479. otherwise) that contradict the conditions of this License, they do not
  480. excuse you from the conditions of this License. If you cannot convey
  481. a covered work so as to satisfy simultaneously your obligations under
  482. this License and any other pertinent obligations, then as a
  483. consequence you may not convey it at all. For example, if you agree
  484. to terms that obligate you to collect a royalty for further conveying
  485. from those to whom you convey the Program, the only way you could
  486. satisfy both those terms and this License would be to refrain entirely
  487. from conveying the Program.
  488. @item Use with the GNU Affero General Public License.
  489. Notwithstanding any other provision of this License, you have
  490. permission to link or combine any covered work with a work licensed
  491. under version 3 of the GNU Affero General Public License into a single
  492. combined work, and to convey the resulting work. The terms of this
  493. License will continue to apply to the part which is the covered work,
  494. but the special requirements of the GNU Affero General Public License,
  495. section 13, concerning interaction through a network will apply to the
  496. combination as such.
  497. @item Revised Versions of this License.
  498. The Free Software Foundation may publish revised and/or new versions
  499. of the GNU General Public License from time to time. Such new
  500. versions will be similar in spirit to the present version, but may
  501. differ in detail to address new problems or concerns.
  502. Each version is given a distinguishing version number. If the Program
  503. specifies that a certain numbered version of the GNU General Public
  504. License ``or any later version'' applies to it, you have the option of
  505. following the terms and conditions either of that numbered version or
  506. of any later version published by the Free Software Foundation. If
  507. the Program does not specify a version number of the GNU General
  508. Public License, you may choose any version ever published by the Free
  509. Software Foundation.
  510. If the Program specifies that a proxy can decide which future versions
  511. of the GNU General Public License can be used, that proxy's public
  512. statement of acceptance of a version permanently authorizes you to
  513. choose that version for the Program.
  514. Later license versions may give you additional or different
  515. permissions. However, no additional obligations are imposed on any
  516. author or copyright holder as a result of your choosing to follow a
  517. later version.
  518. @item Disclaimer of Warranty.
  519. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
  520. APPLICABLE LAW@. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
  521. HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT
  522. WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
  523. LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
  524. A PARTICULAR PURPOSE@. THE ENTIRE RISK AS TO THE QUALITY AND
  525. PERFORMANCE OF THE PROGRAM IS WITH YOU@. SHOULD THE PROGRAM PROVE
  526. DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
  527. CORRECTION.
  528. @item Limitation of Liability.
  529. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  530. WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR
  531. CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
  532. INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES
  533. ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT
  534. NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR
  535. LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM
  536. TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER
  537. PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
  538. @item Interpretation of Sections 15 and 16.
  539. If the disclaimer of warranty and limitation of liability provided
  540. above cannot be given local legal effect according to their terms,
  541. reviewing courts shall apply local law that most closely approximates
  542. an absolute waiver of all civil liability in connection with the
  543. Program, unless a warranty or assumption of liability accompanies a
  544. copy of the Program in return for a fee.
  545. @end enumerate
  546. @heading END OF TERMS AND CONDITIONS
  547. @heading How to Apply These Terms to Your New Programs
  548. If you develop a new program, and you want it to be of the greatest
  549. possible use to the public, the best way to achieve this is to make it
  550. free software which everyone can redistribute and change under these
  551. terms.
  552. To do so, attach the following notices to the program. It is safest
  553. to attach them to the start of each source file to most effectively
  554. state the exclusion of warranty; and each file should have at least
  555. the ``copyright'' line and a pointer to where the full notice is found.
  556. @smallexample
  557. @var{one line to give the program's name and a brief idea of what it does.}
  558. Copyright (C) @var{year} @var{name of author}
  559. This program is free software: you can redistribute it and/or modify
  560. it under the terms of the GNU General Public License as published by
  561. the Free Software Foundation, either version 3 of the License, or (at
  562. your option) any later version.
  563. This program is distributed in the hope that it will be useful, but
  564. WITHOUT ANY WARRANTY; without even the implied warranty of
  565. MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE@. See the GNU
  566. General Public License for more details.
  567. You should have received a copy of the GNU General Public License
  568. along with this program. If not, see @url{http://www.gnu.org/licenses/}.
  569. @end smallexample
  570. Also add information on how to contact you by electronic and paper mail.
  571. If the program does terminal interaction, make it output a short
  572. notice like this when it starts in an interactive mode:
  573. @smallexample
  574. @var{program} Copyright (C) @var{year} @var{name of author}
  575. This program comes with ABSOLUTELY NO WARRANTY; for details type @samp{show w}.
  576. This is free software, and you are welcome to redistribute it
  577. under certain conditions; type @samp{show c} for details.
  578. @end smallexample
  579. The hypothetical commands @samp{show w} and @samp{show c} should show
  580. the appropriate parts of the General Public License. Of course, your
  581. program's commands might be different; for a GUI interface, you would
  582. use an ``about box''.
  583. You should also get your employer (if you work as a programmer) or school,
  584. if any, to sign a ``copyright disclaimer'' for the program, if necessary.
  585. For more information on this, and how to apply and follow the GNU GPL, see
  586. @url{http://www.gnu.org/licenses/}.
  587. The GNU General Public License does not permit incorporating your
  588. program into proprietary programs. If your program is a subroutine
  589. library, you may consider it more useful to permit linking proprietary
  590. applications with the library. If this is what you want to do, use
  591. the GNU Lesser General Public License instead of this License. But
  592. first, please read @url{http://www.gnu.org/philosophy/why-not-lgpl.html}.
