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