  11. <h3 style="text-align: center;">GNU GENERAL PUBLIC LICENSE</h3>
  12. <p style="text-align: center;">Version 3, 29 June 2007</p>
  13. <p>Copyright &copy; 2007 Free Software Foundation, Inc.
  14. &lt;<a href="https://fsf.org/">https://fsf.org/</a>&gt;</p><p>
  15. Everyone is permitted to copy and distribute verbatim copies
  16. of this license document, but changing it is not allowed.</p>
  17. <h3><a name="preamble"></a>Preamble</h3>
  18. <p>The GNU General Public License is a free, copyleft license for
  19. software and other kinds of works.</p>
  20. <p>The licenses for most software and other practical works are designed
  21. to take away your freedom to share and change the works. By contrast,
  22. the GNU General Public License is intended to guarantee your freedom to
  23. share and change all versions of a program--to make sure it remains free
  24. software for all its users. We, the Free Software Foundation, use the
  25. GNU General Public License for most of our software; it applies also to
  26. any other work released this way by its authors. You can apply it to
  27. your programs, too.</p>
  28. <p>When we speak of free software, we are referring to freedom, not
  29. price. Our General Public Licenses are designed to make sure that you
  30. have the freedom to distribute copies of free software (and charge for
  31. them if you wish), that you receive source code or can get it if you
  32. want it, that you can change the software or use pieces of it in new
  33. free programs, and that you know you can do these things.</p>
  34. <p>To protect your rights, we need to prevent others from denying you
  35. these rights or asking you to surrender the rights. Therefore, you have
  36. certain responsibilities if you distribute copies of the software, or if
  37. you modify it: responsibilities to respect the freedom of others.</p>
  38. <p>For example, if you distribute copies of such a program, whether
  39. gratis or for a fee, you must pass on to the recipients the same
  40. freedoms that you received. You must make sure that they, too, receive
  41. or can get the source code. And you must show them these terms so they
  42. know their rights.</p>
  43. <p>Developers that use the GNU GPL protect your rights with two steps:
  44. (1) assert copyright on the software, and (2) offer you this License
  45. giving you legal permission to copy, distribute and/or modify it.</p>
  46. <p>For the developers' and authors' protection, the GPL clearly explains
  47. that there is no warranty for this free software. For both users' and
  48. authors' sake, the GPL requires that modified versions be marked as
  49. changed, so that their problems will not be attributed erroneously to
  50. authors of previous versions.</p>
  51. <p>Some devices are designed to deny users access to install or run
  52. modified versions of the software inside them, although the manufacturer
  53. can do so. This is fundamentally incompatible with the aim of
  54. protecting users' freedom to change the software. The systematic
  55. pattern of such abuse occurs in the area of products for individuals to
  56. use, which is precisely where it is most unacceptable. Therefore, we
  57. have designed this version of the GPL to prohibit the practice for those
  58. products. If such problems arise substantially in other domains, we
  59. stand ready to extend this provision to those domains in future versions
  60. of the GPL, as needed to protect the freedom of users.</p>
  61. <p>Finally, every program is threatened constantly by software patents.
  62. States should not allow patents to restrict development and use of
  63. software on general-purpose computers, but in those that do, we wish to
  64. avoid the special danger that patents applied to a free program could
  65. make it effectively proprietary. To prevent this, the GPL assures that
  66. patents cannot be used to render the program non-free.</p>
  67. <p>The precise terms and conditions for copying, distribution and
  68. modification follow.</p>
  69. <h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
  70. <h4><a name="section0"></a>0. Definitions.</h4>
  71. <p>&ldquo;This License&rdquo; refers to version 3 of the GNU General Public License.</p>
  72. <p>&ldquo;Copyright&rdquo; also means copyright-like laws that apply to other kinds of
  73. works, such as semiconductor masks.</p>
  74. <p>&ldquo;The Program&rdquo; refers to any copyrightable work licensed under this
  75. License. Each licensee is addressed as &ldquo;you&rdquo;. &ldquo;Licensees&rdquo; and
  76. &ldquo;recipients&rdquo; may be individuals or organizations.</p>
  77. <p>To &ldquo;modify&rdquo; a work means to copy from or adapt all or part of the work
  78. in a fashion requiring copyright permission, other than the making of an
  79. exact copy. The resulting work is called a &ldquo;modified version&rdquo; of the
  80. earlier work or a work &ldquo;based on&rdquo; the earlier work.</p>
  81. <p>A &ldquo;covered work&rdquo; means either the unmodified Program or a work based
  82. on the Program.</p>
  83. <p>To &ldquo;propagate&rdquo; a work means to do anything with it that, without
  84. permission, would make you directly or secondarily liable for
  85. infringement under applicable copyright law, except executing it on a
  86. computer or modifying a private copy. Propagation includes copying,
  87. distribution (with or without modification), making available to the
  88. public, and in some countries other activities as well.</p>
  89. <p>To &ldquo;convey&rdquo; a work means any kind of propagation that enables other
  90. parties to make or receive copies. Mere interaction with a user through
  91. a computer network, with no transfer of a copy, is not conveying.</p>
  92. <p>An interactive user interface displays &ldquo;Appropriate Legal Notices&rdquo;
  93. to the extent that it includes a convenient and prominently visible
  94. feature that (1) displays an appropriate copyright notice, and (2)
  95. tells the user that there is no warranty for the work (except to the
  96. extent that warranties are provided), that licensees may convey the
  97. work under this License, and how to view a copy of this License. If
  98. the interface presents a list of user commands or options, such as a
  99. menu, a prominent item in the list meets this criterion.</p>
  100. <h4><a name="section1"></a>1. Source Code.</h4>
  101. <p>The &ldquo;source code&rdquo; for a work means the preferred form of the work
  102. for making modifications to it. &ldquo;Object code&rdquo; means any non-source
  103. form of a work.</p>
  104. <p>A &ldquo;Standard Interface&rdquo; means an interface that either is an official
  105. standard defined by a recognized standards body, or, in the case of
  106. interfaces specified for a particular programming language, one that
  107. is widely used among developers working in that language.</p>
  108. <p>The &ldquo;System Libraries&rdquo; of an executable work include anything, other
  109. than the work as a whole, that (a) is included in the normal form of
  110. packaging a Major Component, but which is not part of that Major
  111. Component, and (b) serves only to enable use of the work with that
  112. Major Component, or to implement a Standard Interface for which an
  113. implementation is available to the public in source code form. A
  114. &ldquo;Major Component&rdquo;, in this context, means a major essential component
  115. (kernel, window system, and so on) of the specific operating system
  116. (if any) on which the executable work runs, or a compiler used to
  117. produce the work, or an object code interpreter used to run it.</p>
  118. <p>The &ldquo;Corresponding Source&rdquo; for a work in object code form means all
  119. the source code needed to generate, install, and (for an executable
  120. work) run the object code and to modify the work, including scripts to
  121. control those activities. However, it does not include the work's
  122. System Libraries, or general-purpose tools or generally available free
  123. programs which are used unmodified in performing those activities but
  124. which are not part of the work. For example, Corresponding Source
  125. includes interface definition files associated with source files for
  126. the work, and the source code for shared libraries and dynamically
  127. linked subprograms that the work is specifically designed to require,
  128. such as by intimate data communication or control flow between those
  129. subprograms and other parts of the work.</p>
  130. <p>The Corresponding Source need not include anything that users
  131. can regenerate automatically from other parts of the Corresponding
  132. Source.</p>
  133. <p>The Corresponding Source for a work in source code form is that
  134. same work.</p>
  135. <h4><a name="section2"></a>2. Basic Permissions.</h4>
  136. <p>All rights granted under this License are granted for the term of
  137. copyright on the Program, and are irrevocable provided the stated
  138. conditions are met. This License explicitly affirms your unlimited
  139. permission to run the unmodified Program. The output from running a
  140. covered work is covered by this License only if the output, given its
  141. content, constitutes a covered work. This License acknowledges your
  142. rights of fair use or other equivalent, as provided by copyright law.</p>
  143. <p>You may make, run and propagate covered works that you do not
  144. convey, without conditions so long as your license otherwise remains
  145. in force. You may convey covered works to others for the sole purpose
  146. of having them make modifications exclusively for you, or provide you
  147. with facilities for running those works, provided that you comply with
  148. the terms of this License in conveying all material for which you do
  149. not control copyright. Those thus making or running the covered works
  150. for you must do so exclusively on your behalf, under your direction
  151. and control, on terms that prohibit them from making any copies of
  152. your copyrighted material outside their relationship with you.</p>
  153. <p>Conveying under any other circumstances is permitted solely under
  154. the conditions stated below. Sublicensing is not allowed; section 10
  155. makes it unnecessary.</p>
  156. <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
  157. <p>No covered work shall be deemed part of an effective technological
  158. measure under any applicable law fulfilling obligations under article
  159. 11 of the WIPO copyright treaty adopted on 20 December 1996, or
  160. similar laws prohibiting or restricting circumvention of such
  161. measures.</p>
  162. <p>When you convey a covered work, you waive any legal power to forbid
  163. circumvention of technological measures to the extent such circumvention
  164. is effected by exercising rights under this License with respect to
  165. the covered work, and you disclaim any intention to limit operation or
  166. modification of the work as a means of enforcing, against the work's
  167. users, your or third parties' legal rights to forbid circumvention of
  168. technological measures.</p>
  169. <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
  170. <p>You may convey verbatim copies of the Program's source code as you
  171. receive it, in any medium, provided that you conspicuously and
  172. appropriately publish on each copy an appropriate copyright notice;
  173. keep intact all notices stating that this License and any
  174. non-permissive terms added in accord with section 7 apply to the code;
  175. keep intact all notices of the absence of any warranty; and give all
  176. recipients a copy of this License along with the Program.</p>
  177. <p>You may charge any price or no price for each copy that you convey,
  178. and you may offer support or warranty protection for a fee.</p>
  179. <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
  180. <p>You may convey a work based on the Program, or the modifications to
  181. produce it from the Program, in the form of source code under the
  182. terms of section 4, provided that you also meet all of these conditions:</p>
  183. <ul>
  184. <li>a) The work must carry prominent notices stating that you modified
  185. it, and giving a relevant date.</li>
  186. <li>b) The work must carry prominent notices stating that it is
  187. released under this License and any conditions added under section
  188. 7. This requirement modifies the requirement in section 4 to
  189. &ldquo;keep intact all notices&rdquo;.</li>
  190. <li>c) You must license the entire work, as a whole, under this
  191. License to anyone who comes into possession of a copy. This
  192. License will therefore apply, along with any applicable section 7
  193. additional terms, to the whole of the work, and all its parts,
  194. regardless of how they are packaged. This License gives no
  195. permission to license the work in any other way, but it does not
  196. invalidate such permission if you have separately received it.</li>
  197. <li>d) If the work has interactive user interfaces, each must display
  198. Appropriate Legal Notices; however, if the Program has interactive
  199. interfaces that do not display Appropriate Legal Notices, your
  200. work need not make them do so.</li>
  201. </ul>
  202. <p>A compilation of a covered work with other separate and independent
  203. works, which are not by their nature extensions of the covered work,
  204. and which are not combined with it such as to form a larger program,
  205. in or on a volume of a storage or distribution medium, is called an
  206. &ldquo;aggregate&rdquo; if the compilation and its resulting copyright are not
  207. used to limit the access or legal rights of the compilation's users
  208. beyond what the individual works permit. Inclusion of a covered work
  209. in an aggregate does not cause this License to apply to the other
  210. parts of the aggregate.</p>
  211. <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
  212. <p>You may convey a covered work in object code form under the terms
  213. of sections 4 and 5, provided that you also convey the
  214. machine-readable Corresponding Source under the terms of this License,
  215. in one of these ways:</p>
  216. <ul>
  217. <li>a) Convey the object code in, or embodied in, a physical product
  218. (including a physical distribution medium), accompanied by the
  219. Corresponding Source fixed on a durable physical medium
  220. customarily used for software interchange.</li>
  221. <li>b) Convey the object code in, or embodied in, a physical product
  222. (including a physical distribution medium), accompanied by a
  223. written offer, valid for at least three years and valid for as
  224. long as you offer spare parts or customer support for that product
  225. model, to give anyone who possesses the object code either (1) a
  226. copy of the Corresponding Source for all the software in the
  227. product that is covered by this License, on a durable physical
  228. medium customarily used for software interchange, for a price no
  229. more than your reasonable cost of physically performing this
  230. conveying of source, or (2) access to copy the
  231. Corresponding Source from a network server at no charge.</li>
  232. <li>c) Convey individual copies of the object code with a copy of the
  233. written offer to provide the Corresponding Source. This
  234. alternative is allowed only occasionally and noncommercially, and
  235. only if you received the object code with such an offer, in accord
  236. with subsection 6b.</li>
  237. <li>d) Convey the object code by offering access from a designated
  238. place (gratis or for a charge), and offer equivalent access to the
  239. Corresponding Source in the same way through the same place at no
  240. further charge. You need not require recipients to copy the
  241. Corresponding Source along with the object code. If the place to
  242. copy the object code is a network server, the Corresponding Source
  243. may be on a different server (operated by you or a third party)
  244. that supports equivalent copying facilities, provided you maintain
  245. clear directions next to the object code saying where to find the
  246. Corresponding Source. Regardless of what server hosts the
  247. Corresponding Source, you remain obligated to ensure that it is
  248. available for as long as needed to satisfy these requirements.</li>
  249. <li>e) Convey the object code using peer-to-peer transmission, provided
  250. you inform other peers where the object code and Corresponding
  251. Source of the work are being offered to the general public at no
  252. charge under subsection 6d.</li>
  253. </ul>
  254. <p>A separable portion of the object code, whose source code is excluded
  255. from the Corresponding Source as a System Library, need not be
  256. included in conveying the object code work.</p>
  257. <p>A &ldquo;User Product&rdquo; is either (1) a &ldquo;consumer product&rdquo;, which means any
  258. tangible personal property which is normally used for personal, family,
  259. or household purposes, or (2) anything designed or sold for incorporation
  260. into a dwelling. In determining whether a product is a consumer product,
  261. doubtful cases shall be resolved in favor of coverage. For a particular
  262. product received by a particular user, &ldquo;normally used&rdquo; refers to a
  263. typical or common use of that class of product, regardless of the status
  264. of the particular user or of the way in which the particular user
  265. actually uses, or expects or is expected to use, the product. A product
  266. is a consumer product regardless of whether the product has substantial
  267. commercial, industrial or non-consumer uses, unless such uses represent
  268. the only significant mode of use of the product.</p>
  269. <p>&ldquo;Installation Information&rdquo; for a User Product means any methods,
  270. procedures, authorization keys, or other information required to install
  271. and execute modified versions of a covered work in that User Product from
  272. a modified version of its Corresponding Source. The information must
  273. suffice to ensure that the continued functioning of the modified object
  274. code is in no case prevented or interfered with solely because
  275. modification has been made.</p>
  276. <p>If you convey an object code work under this section in, or with, or
  277. specifically for use in, a User Product, and the conveying occurs as
  278. part of a transaction in which the right of possession and use of the
  279. User Product is transferred to the recipient in perpetuity or for a
  280. fixed term (regardless of how the transaction is characterized), the
  281. Corresponding Source conveyed under this section must be accompanied
  282. by the Installation Information. But this requirement does not apply
  283. if neither you nor any third party retains the ability to install
  284. modified object code on the User Product (for example, the work has
  285. been installed in ROM).</p>
  286. <p>The requirement to provide Installation Information does not include a
  287. requirement to continue to provide support service, warranty, or updates
  288. for a work that has been modified or installed by the recipient, or for
  289. the User Product in which it has been modified or installed. Access to a
  290. network may be denied when the modification itself materially and
  291. adversely affects the operation of the network or violates the rules and
  292. protocols for communication across the network.</p>
  293. <p>Corresponding Source conveyed, and Installation Information provided,
  294. in accord with this section must be in a format that is publicly
  295. documented (and with an implementation available to the public in
  296. source code form), and must require no special password or key for
  297. unpacking, reading or copying.</p>
  298. <h4><a name="section7"></a>7. Additional Terms.</h4>
  299. <p>&ldquo;Additional permissions&rdquo; are terms that supplement the terms of this
  300. License by making exceptions from one or more of its conditions.
  301. Additional permissions that are applicable to the entire Program shall
  302. be treated as though they were included in this License, to the extent
  303. that they are valid under applicable law. If additional permissions
  304. apply only to part of the Program, that part may be used separately
  305. under those permissions, but the entire Program remains governed by
  306. this License without regard to the additional permissions.</p>
  307. <p>When you convey a copy of a covered work, you may at your option
  308. remove any additional permissions from that copy, or from any part of
  309. it. (Additional permissions may be written to require their own
  310. removal in certain cases when you modify the work.) You may place
  311. additional permissions on material, added by you to a covered work,
  312. for which you have or can give appropriate copyright permission.</p>
  313. <p>Notwithstanding any other provision of this License, for material you
  314. add to a covered work, you may (if authorized by the copyright holders of
  315. that material) supplement the terms of this License with terms:</p>
  316. <ul>
  317. <li>a) Disclaiming warranty or limiting liability differently from the
  318. terms of sections 15 and 16 of this License; or</li>
  319. <li>b) Requiring preservation of specified reasonable legal notices or
  320. author attributions in that material or in the Appropriate Legal
  321. Notices displayed by works containing it; or</li>
  322. <li>c) Prohibiting misrepresentation of the origin of that material, or
  323. requiring that modified versions of such material be marked in
  324. reasonable ways as different from the original version; or</li>
  325. <li>d) Limiting the use for publicity purposes of names of licensors or
  326. authors of the material; or</li>
  327. <li>e) Declining to grant rights under trademark law for use of some
  328. trade names, trademarks, or service marks; or</li>
  329. <li>f) Requiring indemnification of licensors and authors of that
  330. material by anyone who conveys the material (or modified versions of
  331. it) with contractual assumptions of liability to the recipient, for
  332. any liability that these contractual assumptions directly impose on
  333. those licensors and authors.</li>
  334. </ul>
  335. <p>All other non-permissive additional terms are considered &ldquo;further
  336. restrictions&rdquo; within the meaning of section 10. If the Program as you
  337. received it, or any part of it, contains a notice stating that it is
  338. governed by this License along with a term that is a further
  339. restriction, you may remove that term. If a license document contains
  340. a further restriction but permits relicensing or conveying under this
  341. License, you may add to a covered work material governed by the terms
  342. of that license document, provided that the further restriction does
  343. not survive such relicensing or conveying.</p>
  344. <p>If you add terms to a covered work in accord with this section, you
  345. must place, in the relevant source files, a statement of the
  346. additional terms that apply to those files, or a notice indicating
  347. where to find the applicable terms.</p>
  348. <p>Additional terms, permissive or non-permissive, may be stated in the
  349. form of a separately written license, or stated as exceptions;
  350. the above requirements apply either way.</p>
  351. <h4><a name="section8"></a>8. Termination.</h4>
  352. <p>You may not propagate or modify a covered work except as expressly
  353. provided under this License. Any attempt otherwise to propagate or
  354. modify it is void, and will automatically terminate your rights under
  355. this License (including any patent licenses granted under the third
  356. paragraph of section 11).</p>
  357. <p>However, if you cease all violation of this License, then your
  358. license from a particular copyright holder is reinstated (a)
  359. provisionally, unless and until the copyright holder explicitly and
  360. finally terminates your license, and (b) permanently, if the copyright
  361. holder fails to notify you of the violation by some reasonable means
  362. prior to 60 days after the cessation.</p>
  363. <p>Moreover, your license from a particular copyright holder is
  364. reinstated permanently if the copyright holder notifies you of the
  365. violation by some reasonable means, this is the first time you have
  366. received notice of violation of this License (for any work) from that
  367. copyright holder, and you cure the violation prior to 30 days after
  368. your receipt of the notice.</p>
  369. <p>Termination of your rights under this section does not terminate the
  370. licenses of parties who have received copies or rights from you under
  371. this License. If your rights have been terminated and not permanently
  372. reinstated, you do not qualify to receive new licenses for the same
  373. material under section 10.</p>
  374. <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
  375. <p>You are not required to accept this License in order to receive or
  376. run a copy of the Program. Ancillary propagation of a covered work
  377. occurring solely as a consequence of using peer-to-peer transmission
  378. to receive a copy likewise does not require acceptance. However,
  379. nothing other than this License grants you permission to propagate or
  380. modify any covered work. These actions infringe copyright if you do
  381. not accept this License. Therefore, by modifying or propagating a
  382. covered work, you indicate your acceptance of this License to do so.</p>
  383. <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
  384. <p>Each time you convey a covered work, the recipient automatically
  385. receives a license from the original licensors, to run, modify and
  386. propagate that work, subject to this License. You are not responsible
  387. for enforcing compliance by third parties with this License.</p>
  388. <p>An &ldquo;entity transaction&rdquo; is a transaction transferring control of an
  389. organization, or substantially all assets of one, or subdividing an
  390. organization, or merging organizations. If propagation of a covered
  391. work results from an entity transaction, each party to that
  392. transaction who receives a copy of the work also receives whatever
  393. licenses to the work the party's predecessor in interest had or could
  394. give under the previous paragraph, plus a right to possession of the
  395. Corresponding Source of the work from the predecessor in interest, if
  396. the predecessor has it or can get it with reasonable efforts.</p>
  397. <p>You may not impose any further restrictions on the exercise of the
  398. rights granted or affirmed under this License. For example, you may
  399. not impose a license fee, royalty, or other charge for exercise of
  400. rights granted under this License, and you may not initiate litigation
  401. (including a cross-claim or counterclaim in a lawsuit) alleging that
  402. any patent claim is infringed by making, using, selling, offering for
  403. sale, or importing the Program or any portion of it.</p>
  404. <h4><a name="section11"></a>11. Patents.</h4>
  405. <p>A &ldquo;contributor&rdquo; is a copyright holder who authorizes use under this
  406. License of the Program or a work on which the Program is based. The
  407. work thus licensed is called the contributor's &ldquo;contributor version&rdquo;.</p>
  408. <p>A contributor's &ldquo;essential patent claims&rdquo; are all patent claims
  409. owned or controlled by the contributor, whether already acquired or
  410. hereafter acquired, that would be infringed by some manner, permitted
  411. by this License, of making, using, or selling its contributor version,
  412. but do not include claims that would be infringed only as a
  413. consequence of further modification of the contributor version. For
  414. purposes of this definition, &ldquo;control&rdquo; includes the right to grant
  415. patent sublicenses in a manner consistent with the requirements of
  416. this License.</p>
  417. <p>Each contributor grants you a non-exclusive, worldwide, royalty-free
  418. patent license under the contributor's essential patent claims, to
  419. make, use, sell, offer for sale, import and otherwise run, modify and
  420. propagate the contents of its contributor version.</p>
  421. <p>In the following three paragraphs, a &ldquo;patent license&rdquo; is any express
  422. agreement or commitment, however denominated, not to enforce a patent
  423. (such as an express permission to practice a patent or covenant not to
  424. sue for patent infringement). To &ldquo;grant&rdquo; such a patent license to a
  425. party means to make such an agreement or commitment not to enforce a
  426. patent against the party.</p>
  427. <p>If you convey a covered work, knowingly relying on a patent license,
  428. and the Corresponding Source of the work is not available for anyone
  429. to copy, free of charge and under the terms of this License, through a
  430. publicly available network server or other readily accessible means,
  431. then you must either (1) cause the Corresponding Source to be so
  432. available, or (2) arrange to deprive yourself of the benefit of the
  433. patent license for this particular work, or (3) arrange, in a manner
  434. consistent with the requirements of this License, to extend the patent
  435. license to downstream recipients. &ldquo;Knowingly relying&rdquo; means you have
  436. actual knowledge that, but for the patent license, your conveying the
  437. covered work in a country, or your recipient's use of the covered work
  438. in a country, would infringe one or more identifiable patents in that
  439. country that you have reason to believe are valid.</p>
  440. <p>If, pursuant to or in connection with a single transaction or
  441. arrangement, you convey, or propagate by procuring conveyance of, a
  442. covered work, and grant a patent license to some of the parties
  443. receiving the covered work authorizing them to use, propagate, modify
  444. or convey a specific copy of the covered work, then the patent license
  445. you grant is automatically extended to all recipients of the covered
  446. work and works based on it.</p>
  447. <p>A patent license is &ldquo;discriminatory&rdquo; if it does not include within
  448. the scope of its coverage, prohibits the exercise of, or is
  449. conditioned on the non-exercise of one or more of the rights that are
  450. specifically granted under this License. You may not convey a covered
  451. work if you are a party to an arrangement with a third party that is
  452. in the business of distributing software, under which you make payment
  453. to the third party based on the extent of your activity of conveying
  454. the work, and under which the third party grants, to any of the
  455. parties who would receive the covered work from you, a discriminatory
  456. patent license (a) in connection with copies of the covered work
  457. conveyed by you (or copies made from those copies), or (b) primarily
  458. for and in connection with specific products or compilations that
  459. contain the covered work, unless you entered into that arrangement,
  460. or that patent license was granted, prior to 28 March 2007.</p>
  461. <p>Nothing in this License shall be construed as excluding or limiting
  462. any implied license or other defenses to infringement that may
  463. otherwise be available to you under applicable patent law.</p>
  464. <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
  465. <p>If conditions are imposed on you (whether by court order, agreement or
  466. otherwise) that contradict the conditions of this License, they do not
  467. excuse you from the conditions of this License. If you cannot convey a
  468. covered work so as to satisfy simultaneously your obligations under this
  469. License and any other pertinent obligations, then as a consequence you may
  470. not convey it at all. For example, if you agree to terms that obligate you
  471. to collect a royalty for further conveying from those to whom you convey
  472. the Program, the only way you could satisfy both those terms and this
  473. License would be to refrain entirely from conveying the Program.</p>
  474. <h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
  475. <p>Notwithstanding any other provision of this License, you have
  476. permission to link or combine any covered work with a work licensed
  477. under version 3 of the GNU Affero General Public License into a single
  478. combined work, and to convey the resulting work. The terms of this
  479. License will continue to apply to the part which is the covered work,
  480. but the special requirements of the GNU Affero General Public License,
  481. section 13, concerning interaction through a network will apply to the
  482. combination as such.</p>
  483. <h4><a name="section14"></a>14. Revised Versions of this License.</h4>
  484. <p>The Free Software Foundation may publish revised and/or new versions of
  485. the GNU General Public License from time to time. Such new versions will
  486. be similar in spirit to the present version, but may differ in detail to
  487. address new problems or concerns.</p>
  488. <p>Each version is given a distinguishing version number. If the
  489. Program specifies that a certain numbered version of the GNU General
  490. Public License &ldquo;or any later version&rdquo; applies to it, you have the
  491. option of following the terms and conditions either of that numbered
  492. version or of any later version published by the Free Software
  493. Foundation. If the Program does not specify a version number of the
  494. GNU General Public License, you may choose any version ever published
  495. by the Free Software Foundation.</p>
  496. <p>If the Program specifies that a proxy can decide which future
  497. versions of the GNU General Public License can be used, that proxy's
  498. public statement of acceptance of a version permanently authorizes you
  499. to choose that version for the Program.</p>
  500. <p>Later license versions may give you additional or different
  501. permissions. However, no additional obligations are imposed on any
  502. author or copyright holder as a result of your choosing to follow a
  503. later version.</p>
  504. <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
  505. <p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
  506. APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
  507. HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM &ldquo;AS IS&rdquo; WITHOUT WARRANTY
  508. OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
  509. THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  510. PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
  511. IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
  512. ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
  513. <h4><a name="section16"></a>16. Limitation of Liability.</h4>
  514. <p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  515. WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
  516. THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
  517. GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
  518. USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
  519. DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
  520. PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
  521. EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
  522. SUCH DAMAGES.</p>
  523. <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
  524. <p>If the disclaimer of warranty and limitation of liability provided
  525. above cannot be given local legal effect according to their terms,
  526. reviewing courts shall apply local law that most closely approximates
  527. an absolute waiver of all civil liability in connection with the
  528. Program, unless a warranty or assumption of liability accompanies a
  529. copy of the Program in return for a fee.</p>
  530. <p>END OF TERMS AND CONDITIONS</p>
  531. <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
  532. <p>If you develop a new program, and you want it to be of the greatest
  533. possible use to the public, the best way to achieve this is to make it
  534. free software which everyone can redistribute and change under these terms.</p>
  535. <p>To do so, attach the following notices to the program. It is safest
  536. to attach them to the start of each source file to most effectively
  537. state the exclusion of warranty; and each file should have at least
  538. the &ldquo;copyright&rdquo; line and a pointer to where the full notice is found.</p>
  539. <pre> &lt;one line to give the program's name and a brief idea of what it does.&gt;
  540. Copyright (C) &lt;year&gt; &lt;name of author&gt;
  541. This program is free software: you can redistribute it and/or modify
  542. it under the terms of the GNU General Public License as published by
  543. the Free Software Foundation, either version 3 of the License, or
  544. (at your option) any later version.
  545. This program is distributed in the hope that it will be useful,
  546. but WITHOUT ANY WARRANTY; without even the implied warranty of
  547. MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
  548. GNU General Public License for more details.
  549. You should have received a copy of the GNU General Public License
  550. along with this program. If not, see &lt;https://www.gnu.org/licenses/&gt;.
  551. </pre>
  552. <p>Also add information on how to contact you by electronic and paper mail.</p>
  553. <p>If the program does terminal interaction, make it output a short
  554. notice like this when it starts in an interactive mode:</p>
  555. <pre> &lt;program&gt; Copyright (C) &lt;year&gt; &lt;name of author&gt;
  556. This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
  557. This is free software, and you are welcome to redistribute it
  558. under certain conditions; type `show c' for details.
  559. </pre>
  560. <p>The hypothetical commands `show w' and `show c' should show the appropriate
  561. parts of the General Public License. Of course, your program's commands
  562. might be different; for a GUI interface, you would use an &ldquo;about box&rdquo;.</p>
  563. <p>You should also get your employer (if you work as a programmer) or school,
  564. if any, to sign a &ldquo;copyright disclaimer&rdquo; for the program, if necessary.
  565. For more information on this, and how to apply and follow the GNU GPL, see
  566. &lt;<a href="https://www.gnu.org/licenses/">https://www.gnu.org/licenses/</a>&gt;.</p>
  567. <p>The GNU General Public License does not permit incorporating your program
  568. into proprietary programs. If your program is a subroutine library, you
  569. may consider it more useful to permit linking proprietary applications with
  570. the library. If this is what you want to do, use the GNU Lesser General
  571. Public License instead of this License. But first, please read
