  5. 2 Version 3, 19 November 2007
  6. 3
  7. 4 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
  8. 5 Everyone is permitted to copy and distribute verbatim copies
  9. 6 of this license document, but changing it is not allowed.
  10. 7
  11. 8 Preamble
  12. 9
  13. 10 The GNU Affero General Public License is a free, copyleft license for
  14. 11 software and other kinds of works, specifically designed to ensure
  15. 12 cooperation with the community in the case of network server software.
  16. 13
  17. 14 The licenses for most software and other practical works are designed
  18. 15 to take away your freedom to share and change the works. By contrast,
  19. 16 our General Public Licenses are intended to guarantee your freedom to
  20. 17 share and change all versions of a program--to make sure it remains free
  21. 18 software for all its users.
  22. 19
  23. 20 When we speak of free software, we are referring to freedom, not
  24. 21 price. Our General Public Licenses are designed to make sure that you
  25. 22 have the freedom to distribute copies of free software (and charge for
  26. 23 them if you wish), that you receive source code or can get it if you
  27. 24 want it, that you can change the software or use pieces of it in new
  28. 25 free programs, and that you know you can do these things.
  29. 26
  30. 27 Developers that use our General Public Licenses protect your rights
  31. 28 with two steps: (1) assert copyright on the software, and (2) offer
  32. 29 you this License which gives you legal permission to copy, distribute
  33. 30 and/or modify the software.
  34. 31
  35. 32 A secondary benefit of defending all users' freedom is that
  36. 33 improvements made in alternate versions of the program, if they
  37. 34 receive widespread use, become available for other developers to
  38. 35 incorporate. Many developers of free software are heartened and
  39. 36 encouraged by the resulting cooperation. However, in the case of
  40. 37 software used on network servers, this result may fail to come about.
  41. 38 The GNU General Public License permits making a modified version and
  42. 39 letting the public access it on a server without ever releasing its
  43. 40 source code to the public.
  44. 41
  45. 42 The GNU Affero General Public License is designed specifically to
  46. 43 ensure that, in such cases, the modified source code becomes available
  47. 44 to the community. It requires the operator of a network server to
  48. 45 provide the source code of the modified version running there to the
  49. 46 users of that server. Therefore, public use of a modified version, on
  50. 47 a publicly accessible server, gives the public access to the source
  51. 48 code of the modified version.
  52. 49
  53. 50 An older license, called the Affero General Public License and
  54. 51 published by Affero, was designed to accomplish similar goals. This is
  55. 52 a different license, not a version of the Affero GPL, but Affero has
  56. 53 released a new version of the Affero GPL which permits relicensing under
  57. 54 this license.
  58. 55
  59. 56 The precise terms and conditions for copying, distribution and
  60. 57 modification follow.
  61. 58
  62. 59 TERMS AND CONDITIONS
  63. 60
  64. 61 0. Definitions.
  65. 62
  66. 63 "This License" refers to version 3 of the GNU Affero General Public License.
  67. 64
  68. 65 "Copyright" also means copyright-like laws that apply to other kinds of
  69. 66 works, such as semiconductor masks.
  70. 67
  71. 68 "The Program" refers to any copyrightable work licensed under this
  72. 69 License. Each licensee is addressed as "you". "Licensees" and
  73. 70 "recipients" may be individuals or organizations.
  74. 71
  75. 72 To "modify" a work means to copy from or adapt all or part of the work
  76. 73 in a fashion requiring copyright permission, other than the making of an
  77. 74 exact copy. The resulting work is called a "modified version" of the
  78. 75 earlier work or a work "based on" the earlier work.
  79. 76
  80. 77 A "covered work" means either the unmodified Program or a work based
  81. 78 on the Program.
  82. 79
  83. 80 To "propagate" a work means to do anything with it that, without
  84. 81 permission, would make you directly or secondarily liable for
  85. 82 infringement under applicable copyright law, except executing it on a
  86. 83 computer or modifying a private copy. Propagation includes copying,
  87. 84 distribution (with or without modification), making available to the
  88. 85 public, and in some countries other activities as well.
  89. 86
  90. 87 To "convey" a work means any kind of propagation that enables other
  91. 88 parties to make or receive copies. Mere interaction with a user through
  92. 89 a computer network, with no transfer of a copy, is not conveying.
  93. 90
  94. 91 An interactive user interface displays "Appropriate Legal Notices"
  95. 92 to the extent that it includes a convenient and prominently visible
  96. 93 feature that (1) displays an appropriate copyright notice, and (2)
  97. 94 tells the user that there is no warranty for the work (except to the
  98. 95 extent that warranties are provided), that licensees may convey the
  99. 96 work under this License, and how to view a copy of this License. If
  100. 97 the interface presents a list of user commands or options, such as a
  101. 98 menu, a prominent item in the list meets this criterion.
  102. 99
  103. 100 1. Source Code.
  104. 101
  105. 102 The "source code" for a work means the preferred form of the work
  106. 103 for making modifications to it. "Object code" means any non-source
  107. 104 form of a work.
  108. 105
  109. 106 A "Standard Interface" means an interface that either is an official
  110. 107 standard defined by a recognized standards body, or, in the case of
  111. 108 interfaces specified for a particular programming language, one that
  112. 109 is widely used among developers working in that language.
  113. 110
  114. 111 The "System Libraries" of an executable work include anything, other
  115. 112 than the work as a whole, that (a) is included in the normal form of
  116. 113 packaging a Major Component, but which is not part of that Major
  117. 114 Component, and (b) serves only to enable use of the work with that
  118. 115 Major Component, or to implement a Standard Interface for which an
  119. 116 implementation is available to the public in source code form. A
  120. 117 "Major Component", in this context, means a major essential component
  121. 118 (kernel, window system, and so on) of the specific operating system
  122. 119 (if any) on which the executable work runs, or a compiler used to
  123. 120 produce the work, or an object code interpreter used to run it.
  124. 121
  125. 122 The "Corresponding Source" for a work in object code form means all
  126. 123 the source code needed to generate, install, and (for an executable
  127. 124 work) run the object code and to modify the work, including scripts to
  128. 125 control those activities. However, it does not include the work's
  129. 126 System Libraries, or general-purpose tools or generally available free
  130. 127 programs which are used unmodified in performing those activities but
  131. 128 which are not part of the work. For example, Corresponding Source
  132. 129 includes interface definition files associated with source files for
  133. 130 the work, and the source code for shared libraries and dynamically
  134. 131 linked subprograms that the work is specifically designed to require,
  135. 132 such as by intimate data communication or control flow between those
  136. 133 subprograms and other parts of the work.
  137. 134
  138. 135 The Corresponding Source need not include anything that users
  139. 136 can regenerate automatically from other parts of the Corresponding
  140. 137 Source.
  141. 138
  142. 139 The Corresponding Source for a work in source code form is that
  143. 140 same work.
  144. 141
  145. 142 2. Basic Permissions.
  146. 143
  147. 144 All rights granted under this License are granted for the term of
  148. 145 copyright on the Program, and are irrevocable provided the stated
  149. 146 conditions are met. This License explicitly affirms your unlimited
  150. 147 permission to run the unmodified Program. The output from running a
  151. 148 covered work is covered by this License only if the output, given its
  152. 149 content, constitutes a covered work. This License acknowledges your
  153. 150 rights of fair use or other equivalent, as provided by copyright law.
  154. 151
  155. 152 You may make, run and propagate covered works that you do not
  156. 153 convey, without conditions so long as your license otherwise remains
  157. 154 in force. You may convey covered works to others for the sole purpose
  158. 155 of having them make modifications exclusively for you, or provide you
  159. 156 with facilities for running those works, provided that you comply with
  160. 157 the terms of this License in conveying all material for which you do
  161. 158 not control copyright. Those thus making or running the covered works
  162. 159 for you must do so exclusively on your behalf, under your direction
  163. 160 and control, on terms that prohibit them from making any copies of
  164. 161 your copyrighted material outside their relationship with you.
  165. 162
  166. 163 Conveying under any other circumstances is permitted solely under
  167. 164 the conditions stated below. Sublicensing is not allowed; section 10
  168. 165 makes it unnecessary.
  169. 166
  170. 167 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  171. 168
  172. 169 No covered work shall be deemed part of an effective technological
  173. 170 measure under any applicable law fulfilling obligations under article
  174. 171 11 of the WIPO copyright treaty adopted on 20 December 1996, or
  175. 172 similar laws prohibiting or restricting circumvention of such
  176. 173 measures.
  177. 174
  178. 175 When you convey a covered work, you waive any legal power to forbid
  179. 176 circumvention of technological measures to the extent such circumvention
  180. 177 is effected by exercising rights under this License with respect to
  181. 178 the covered work, and you disclaim any intention to limit operation or
  182. 179 modification of the work as a means of enforcing, against the work's
  183. 180 users, your or third parties' legal rights to forbid circumvention of
  184. 181 technological measures.
  185. 182
  186. 183 4. Conveying Verbatim Copies.
  187. 184
  188. 185 You may convey verbatim copies of the Program's source code as you
  189. 186 receive it, in any medium, provided that you conspicuously and
  190. 187 appropriately publish on each copy an appropriate copyright notice;
  191. 188 keep intact all notices stating that this License and any
  192. 189 non-permissive terms added in accord with section 7 apply to the code;
  193. 190 keep intact all notices of the absence of any warranty; and give all
  194. 191 recipients a copy of this License along with the Program.
  195. 192
  196. 193 You may charge any price or no price for each copy that you convey,
  197. 194 and you may offer support or warranty protection for a fee.
  198. 195
  199. 196 5. Conveying Modified Source Versions.
  200. 197
  201. 198 You may convey a work based on the Program, or the modifications to
  202. 199 produce it from the Program, in the form of source code under the
  203. 200 terms of section 4, provided that you also meet all of these conditions:
  204. 201
  205. 202 a) The work must carry prominent notices stating that you modified
  206. 203 it, and giving a relevant date.
  207. 204
  208. 205 b) The work must carry prominent notices stating that it is
  209. 206 released under this License and any conditions added under section
  210. 207 7. This requirement modifies the requirement in section 4 to
  211. 208 "keep intact all notices".
  212. 209
  213. 210 c) You must license the entire work, as a whole, under this
  214. 211 License to anyone who comes into possession of a copy. This
  215. 212 License will therefore apply, along with any applicable section 7
  216. 213 additional terms, to the whole of the work, and all its parts,
  217. 214 regardless of how they are packaged. This License gives no
  218. 215 permission to license the work in any other way, but it does not
  219. 216 invalidate such permission if you have separately received it.
  220. 217
  221. 218 d) If the work has interactive user interfaces, each must display
  222. 219 Appropriate Legal Notices; however, if the Program has interactive
  223. 220 interfaces that do not display Appropriate Legal Notices, your
  224. 221 work need not make them do so.
  225. 222
  226. 223 A compilation of a covered work with other separate and independent
  227. 224 works, which are not by their nature extensions of the covered work,
  228. 225 and which are not combined with it such as to form a larger program,
  229. 226 in or on a volume of a storage or distribution medium, is called an
  230. 227 "aggregate" if the compilation and its resulting copyright are not
  231. 228 used to limit the access or legal rights of the compilation's users
  232. 229 beyond what the individual works permit. Inclusion of a covered work
  233. 230 in an aggregate does not cause this License to apply to the other
  234. 231 parts of the aggregate.
  235. 232
  236. 233 6. Conveying Non-Source Forms.
  237. 234
  238. 235 You may convey a covered work in object code form under the terms
  239. 236 of sections 4 and 5, provided that you also convey the
  240. 237 machine-readable Corresponding Source under the terms of this License,
  241. 238 in one of these ways:
  242. 239
  243. 240 a) Convey the object code in, or embodied in, a physical product
  244. 241 (including a physical distribution medium), accompanied by the
  245. 242 Corresponding Source fixed on a durable physical medium
  246. 243 customarily used for software interchange.
  247. 244
  248. 245 b) Convey the object code in, or embodied in, a physical product
  249. 246 (including a physical distribution medium), accompanied by a
  250. 247 written offer, valid for at least three years and valid for as
  251. 248 long as you offer spare parts or customer support for that product
  252. 249 model, to give anyone who possesses the object code either (1) a
  253. 250 copy of the Corresponding Source for all the software in the
  254. 251 product that is covered by this License, on a durable physical
  255. 252 medium customarily used for software interchange, for a price no
  256. 253 more than your reasonable cost of physically performing this
  257. 254 conveying of source, or (2) access to copy the
  258. 255 Corresponding Source from a network server at no charge.
  259. 256
  260. 257 c) Convey individual copies of the object code with a copy of the
  261. 258 written offer to provide the Corresponding Source. This
  262. 259 alternative is allowed only occasionally and noncommercially, and
  263. 260 only if you received the object code with such an offer, in accord
  264. 261 with subsection 6b.
  265. 262
  266. 263 d) Convey the object code by offering access from a designated
  267. 264 place (gratis or for a charge), and offer equivalent access to the
  268. 265 Corresponding Source in the same way through the same place at no
  269. 266 further charge. You need not require recipients to copy the
  270. 267 Corresponding Source along with the object code. If the place to
  271. 268 copy the object code is a network server, the Corresponding Source
  272. 269 may be on a different server (operated by you or a third party)
  273. 270 that supports equivalent copying facilities, provided you maintain
  274. 271 clear directions next to the object code saying where to find the
  275. 272 Corresponding Source. Regardless of what server hosts the
  276. 273 Corresponding Source, you remain obligated to ensure that it is
  277. 274 available for as long as needed to satisfy these requirements.
  278. 275
  279. 276 e) Convey the object code using peer-to-peer transmission, provided
  280. 277 you inform other peers where the object code and Corresponding
  281. 278 Source of the work are being offered to the general public at no
  282. 279 charge under subsection 6d.
  283. 280
  284. 281 A separable portion of the object code, whose source code is excluded
  285. 282 from the Corresponding Source as a System Library, need not be
  286. 283 included in conveying the object code work.
  287. 284
  288. 285 A "User Product" is either (1) a "consumer product", which means any
  289. 286 tangible personal property which is normally used for personal, family,
  290. 287 or household purposes, or (2) anything designed or sold for incorporation
  291. 288 into a dwelling. In determining whether a product is a consumer product,
  292. 289 doubtful cases shall be resolved in favor of coverage. For a particular
  293. 290 product received by a particular user, "normally used" refers to a
  294. 291 typical or common use of that class of product, regardless of the status
  295. 292 of the particular user or of the way in which the particular user
  296. 293 actually uses, or expects or is expected to use, the product. A product
  297. 294 is a consumer product regardless of whether the product has substantial
  298. 295 commercial, industrial or non-consumer uses, unless such uses represent
  299. 296 the only significant mode of use of the product.
  300. 297
  301. 298 "Installation Information" for a User Product means any methods,
  302. 299 procedures, authorization keys, or other information required to install
  303. 300 and execute modified versions of a covered work in that User Product from
  304. 301 a modified version of its Corresponding Source. The information must
  305. 302 suffice to ensure that the continued functioning of the modified object
  306. 303 code is in no case prevented or interfered with solely because
  307. 304 modification has been made.
  308. 305
  309. 306 If you convey an object code work under this section in, or with, or
  310. 307 specifically for use in, a User Product, and the conveying occurs as
  311. 308 part of a transaction in which the right of possession and use of the
  312. 309 User Product is transferred to the recipient in perpetuity or for a
  313. 310 fixed term (regardless of how the transaction is characterized), the
  314. 311 Corresponding Source conveyed under this section must be accompanied
  315. 312 by the Installation Information. But this requirement does not apply
  316. 313 if neither you nor any third party retains the ability to install
  317. 314 modified object code on the User Product (for example, the work has
  318. 315 been installed in ROM).
  319. 316
  320. 317 The requirement to provide Installation Information does not include a
  321. 318 requirement to continue to provide support service, warranty, or updates
  322. 319 for a work that has been modified or installed by the recipient, or for
  323. 320 the User Product in which it has been modified or installed. Access to a
  324. 321 network may be denied when the modification itself materially and
  325. 322 adversely affects the operation of the network or violates the rules and
  326. 323 protocols for communication across the network.
  327. 324
  328. 325 Corresponding Source conveyed, and Installation Information provided,
  329. 326 in accord with this section must be in a format that is publicly
  330. 327 documented (and with an implementation available to the public in
  331. 328 source code form), and must require no special password or key for
  332. 329 unpacking, reading or copying.
  333. 330
  334. 331 7. Additional Terms.
  335. 332
  336. 333 "Additional permissions" are terms that supplement the terms of this
  337. 334 License by making exceptions from one or more of its conditions.
  338. 335 Additional permissions that are applicable to the entire Program shall
  339. 336 be treated as though they were included in this License, to the extent
  340. 337 that they are valid under applicable law. If additional permissions
  341. 338 apply only to part of the Program, that part may be used separately
  342. 339 under those permissions, but the entire Program remains governed by
  343. 340 this License without regard to the additional permissions.
  344. 341
  345. 342 When you convey a copy of a covered work, you may at your option
  346. 343 remove any additional permissions from that copy, or from any part of
  347. 344 it. (Additional permissions may be written to require their own
  348. 345 removal in certain cases when you modify the work.) You may place
  349. 346 additional permissions on material, added by you to a covered work,
  350. 347 for which you have or can give appropriate copyright permission.
  351. 348
  352. 349 Notwithstanding any other provision of this License, for material you
  353. 350 add to a covered work, you may (if authorized by the copyright holders of
  354. 351 that material) supplement the terms of this License with terms:
  355. 352
  356. 353 a) Disclaiming warranty or limiting liability differently from the
  357. 354 terms of sections 15 and 16 of this License; or
  358. 355
  359. 356 b) Requiring preservation of specified reasonable legal notices or
  360. 357 author attributions in that material or in the Appropriate Legal
  361. 358 Notices displayed by works containing it; or
  362. 359
  363. 360 c) Prohibiting misrepresentation of the origin of that material, or
  364. 361 requiring that modified versions of such material be marked in
  365. 362 reasonable ways as different from the original version; or
  366. 363
  367. 364 d) Limiting the use for publicity purposes of names of licensors or
  368. 365 authors of the material; or
  369. 366
  370. 367 e) Declining to grant rights under trademark law for use of some
  371. 368 trade names, trademarks, or service marks; or
  372. 369
  373. 370 f) Requiring indemnification of licensors and authors of that
  374. 371 material by anyone who conveys the material (or modified versions of
  375. 372 it) with contractual assumptions of liability to the recipient, for
  376. 373 any liability that these contractual assumptions directly impose on
  377. 374 those licensors and authors.
  378. 375
  379. 376 All other non-permissive additional terms are considered "further
  380. 377 restrictions" within the meaning of section 10. If the Program as you
  381. 378 received it, or any part of it, contains a notice stating that it is
  382. 379 governed by this License along with a term that is a further
  383. 380 restriction, you may remove that term. If a license document contains
  384. 381 a further restriction but permits relicensing or conveying under this
  385. 382 License, you may add to a covered work material governed by the terms
  386. 383 of that license document, provided that the further restriction does
  387. 384 not survive such relicensing or conveying.
  388. 385
  389. 386 If you add terms to a covered work in accord with this section, you
  390. 387 must place, in the relevant source files, a statement of the
  391. 388 additional terms that apply to those files, or a notice indicating
  392. 389 where to find the applicable terms.
  393. 390
  394. 391 Additional terms, permissive or non-permissive, may be stated in the
  395. 392 form of a separately written license, or stated as exceptions;
  396. 393 the above requirements apply either way.
  397. 394
  398. 395 8. Termination.
  399. 396
  400. 397 You may not propagate or modify a covered work except as expressly
  401. 398 provided under this License. Any attempt otherwise to propagate or
  402. 399 modify it is void, and will automatically terminate your rights under
  403. 400 this License (including any patent licenses granted under the third
  404. 401 paragraph of section 11).
  405. 402
  406. 403 However, if you cease all violation of this License, then your
  407. 404 license from a particular copyright holder is reinstated (a)
  408. 405 provisionally, unless and until the copyright holder explicitly and
  409. 406 finally terminates your license, and (b) permanently, if the copyright
  410. 407 holder fails to notify you of the violation by some reasonable means
  411. 408 prior to 60 days after the cessation.
  412. 409
  413. 410 Moreover, your license from a particular copyright holder is
  414. 411 reinstated permanently if the copyright holder notifies you of the
  415. 412 violation by some reasonable means, this is the first time you have
  416. 413 received notice of violation of this License (for any work) from that
  417. 414 copyright holder, and you cure the violation prior to 30 days after
  418. 415 your receipt of the notice.
  419. 416
  420. 417 Termination of your rights under this section does not terminate the
  421. 418 licenses of parties who have received copies or rights from you under
  422. 419 this License. If your rights have been terminated and not permanently
  423. 420 reinstated, you do not qualify to receive new licenses for the same
  424. 421 material under section 10.
  425. 422
  426. 423 9. Acceptance Not Required for Having Copies.
  427. 424
  428. 425 You are not required to accept this License in order to receive or
  429. 426 run a copy of the Program. Ancillary propagation of a covered work
  430. 427 occurring solely as a consequence of using peer-to-peer transmission
  431. 428 to receive a copy likewise does not require acceptance. However,
  432. 429 nothing other than this License grants you permission to propagate or
  433. 430 modify any covered work. These actions infringe copyright if you do
  434. 431 not accept this License. Therefore, by modifying or propagating a
  435. 432 covered work, you indicate your acceptance of this License to do so.
  436. 433
  437. 434 10. Automatic Licensing of Downstream Recipients.
  438. 435
  439. 436 Each time you convey a covered work, the recipient automatically
  440. 437 receives a license from the original licensors, to run, modify and
  441. 438 propagate that work, subject to this License. You are not responsible
  442. 439 for enforcing compliance by third parties with this License.
  443. 440
  444. 441 An "entity transaction" is a transaction transferring control of an
  445. 442 organization, or substantially all assets of one, or subdividing an
  446. 443 organization, or merging organizations. If propagation of a covered
  447. 444 work results from an entity transaction, each party to that
  448. 445 transaction who receives a copy of the work also receives whatever
  449. 446 licenses to the work the party's predecessor in interest had or could
  450. 447 give under the previous paragraph, plus a right to possession of the
  451. 448 Corresponding Source of the work from the predecessor in interest, if
  452. 449 the predecessor has it or can get it with reasonable efforts.
  453. 450
  454. 451 You may not impose any further restrictions on the exercise of the
  455. 452 rights granted or affirmed under this License. For example, you may
  456. 453 not impose a license fee, royalty, or other charge for exercise of
  457. 454 rights granted under this License, and you may not initiate litigation
  458. 455 (including a cross-claim or counterclaim in a lawsuit) alleging that
  459. 456 any patent claim is infringed by making, using, selling, offering for
  460. 457 sale, or importing the Program or any portion of it.
  461. 458
  462. 459 11. Patents.
  463. 460
  464. 461 A "contributor" is a copyright holder who authorizes use under this
  465. 462 License of the Program or a work on which the Program is based. The
  466. 463 work thus licensed is called the contributor's "contributor version".
  467. 464
  468. 465 A contributor's "essential patent claims" are all patent claims
  469. 466 owned or controlled by the contributor, whether already acquired or
  470. 467 hereafter acquired, that would be infringed by some manner, permitted
  471. 468 by this License, of making, using, or selling its contributor version,
  472. 469 but do not include claims that would be infringed only as a
  473. 470 consequence of further modification of the contributor version. For
  474. 471 purposes of this definition, "control" includes the right to grant
  475. 472 patent sublicenses in a manner consistent with the requirements of
  476. 473 this License.
  477. 474
  478. 475 Each contributor grants you a non-exclusive, worldwide, royalty-free
  479. 476 patent license under the contributor's essential patent claims, to
  480. 477 make, use, sell, offer for sale, import and otherwise run, modify and
  481. 478 propagate the contents of its contributor version.
  482. 479
  483. 480 In the following three paragraphs, a "patent license" is any express
  484. 481 agreement or commitment, however denominated, not to enforce a patent
  485. 482 (such as an express permission to practice a patent or covenant not to
  486. 483 sue for patent infringement). To "grant" such a patent license to a
  487. 484 party means to make such an agreement or commitment not to enforce a
  488. 485 patent against the party.
  489. 486
  490. 487 If you convey a covered work, knowingly relying on a patent license,
  491. 488 and the Corresponding Source of the work is not available for anyone
  492. 489 to copy, free of charge and under the terms of this License, through a
  493. 490 publicly available network server or other readily accessible means,
  494. 491 then you must either (1) cause the Corresponding Source to be so
  495. 492 available, or (2) arrange to deprive yourself of the benefit of the
  496. 493 patent license for this particular work, or (3) arrange, in a manner
  497. 494 consistent with the requirements of this License, to extend the patent
  498. 495 license to downstream recipients. "Knowingly relying" means you have
  499. 496 actual knowledge that, but for the patent license, your conveying the
  500. 497 covered work in a country, or your recipient's use of the covered work
  501. 498 in a country, would infringe one or more identifiable patents in that
  502. 499 country that you have reason to believe are valid.
  503. 500
  504. 501 If, pursuant to or in connection with a single transaction or
  505. 502 arrangement, you convey, or propagate by procuring conveyance of, a
  506. 503 covered work, and grant a patent license to some of the parties
  507. 504 receiving the covered work authorizing them to use, propagate, modify
  508. 505 or convey a specific copy of the covered work, then the patent license
  509. 506 you grant is automatically extended to all recipients of the covered
  510. 507 work and works based on it.
  511. 508
  512. 509 A patent license is "discriminatory" if it does not include within
  513. 510 the scope of its coverage, prohibits the exercise of, or is
  514. 511 conditioned on the non-exercise of one or more of the rights that are
  515. 512 specifically granted under this License. You may not convey a covered
  516. 513 work if you are a party to an arrangement with a third party that is
  517. 514 in the business of distributing software, under which you make payment
  518. 515 to the third party based on the extent of your activity of conveying
  519. 516 the work, and under which the third party grants, to any of the
  520. 517 parties who would receive the covered work from you, a discriminatory
  521. 518 patent license (a) in connection with copies of the covered work
  522. 519 conveyed by you (or copies made from those copies), or (b) primarily
  523. 520 for and in connection with specific products or compilations that
  524. 521 contain the covered work, unless you entered into that arrangement,
  525. 522 or that patent license was granted, prior to 28 March 2007.
  526. 523
  527. 524 Nothing in this License shall be construed as excluding or limiting
  528. 525 any implied license or other defenses to infringement that may
  529. 526 otherwise be available to you under applicable patent law.
  530. 527
  531. 528 12. No Surrender of Others' Freedom.
  532. 529
  533. 530 If conditions are imposed on you (whether by court order, agreement or
  534. 531 otherwise) that contradict the conditions of this License, they do not
  535. 532 excuse you from the conditions of this License. If you cannot convey a
  536. 533 covered work so as to satisfy simultaneously your obligations under this
  537. 534 License and any other pertinent obligations, then as a consequence you may
  538. 535 not convey it at all. For example, if you agree to terms that obligate you
  539. 536 to collect a royalty for further conveying from those to whom you convey
  540. 537 the Program, the only way you could satisfy both those terms and this
  541. 538 License would be to refrain entirely from conveying the Program.
  542. 539
  543. 540 13. Remote Network Interaction; Use with the GNU General Public License.
  544. 541
  545. 542 Notwithstanding any other provision of this License, if you modify the
  546. 543 Program, your modified version must prominently offer all users
  547. 544 interacting with it remotely through a computer network (if your version
  548. 545 supports such interaction) an opportunity to receive the Corresponding
  549. 546 Source of your version by providing access to the Corresponding Source
  550. 547 from a network server at no charge, through some standard or customary
  551. 548 means of facilitating copying of software. This Corresponding Source
  552. 549 shall include the Corresponding Source for any work covered by version 3
  553. 550 of the GNU General Public License that is incorporated pursuant to the
  554. 551 following paragraph.
  555. 552
  556. 553 Notwithstanding any other provision of this License, you have
  557. 554 permission to link or combine any covered work with a work licensed
  558. 555 under version 3 of the GNU General Public License into a single
  559. 556 combined work, and to convey the resulting work. The terms of this
  560. 557 License will continue to apply to the part which is the covered work,
  561. 558 but the work with which it is combined will remain governed by version
  562. 559 3 of the GNU General Public License.
  563. 560
  564. 561 14. Revised Versions of this License.
  565. 562
  566. 563 The Free Software Foundation may publish revised and/or new versions of
  567. 564 the GNU Affero General Public License from time to time. Such new versions
  568. 565 will be similar in spirit to the present version, but may differ in detail to
  569. 566 address new problems or concerns.
  570. 567
  571. 568 Each version is given a distinguishing version number. If the
  572. 569 Program specifies that a certain numbered version of the GNU Affero General
  573. 570 Public License "or any later version" applies to it, you have the
  574. 571 option of following the terms and conditions either of that numbered
  575. 572 version or of any later version published by the Free Software
  576. 573 Foundation. If the Program does not specify a version number of the
  577. 574 GNU Affero General Public License, you may choose any version ever published
  578. 575 by the Free Software Foundation.
  579. 576
  580. 577 If the Program specifies that a proxy can decide which future
  581. 578 versions of the GNU Affero General Public License can be used, that proxy's
  582. 579 public statement of acceptance of a version permanently authorizes you
  583. 580 to choose that version for the Program.
  584. 581
  585. 582 Later license versions may give you additional or different
  586. 583 permissions. However, no additional obligations are imposed on any
  587. 584 author or copyright holder as a result of your choosing to follow a
  588. 585 later version.
  589. 586
  590. 587 15. Disclaimer of Warranty.
  591. 588
  592. 589 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
  593. 590 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
  594. 591 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
  595. 592 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
  596. 593 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  597. 594 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
  598. 595 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
  599. 596 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  600. 597
  601. 598 16. Limitation of Liability.
  602. 599
  603. 600 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  604. 601 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
  605. 602 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
  606. 603 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
  607. 604 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
  608. 605 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
  609. 606 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
  610. 607 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
  611. 608 SUCH DAMAGES.
  612. 609
  613. 610 17. Interpretation of Sections 15 and 16.
  614. 611
  615. 612 If the disclaimer of warranty and limitation of liability provided
  616. 613 above cannot be given local legal effect according to their terms,
  617. 614 reviewing courts shall apply local law that most closely approximates
  618. 615 an absolute waiver of all civil liability in connection with the
  619. 616 Program, unless a warranty or assumption of liability accompanies a
  620. 617 copy of the Program in return for a fee.
  621. 618
  622. 619 END OF TERMS AND CONDITIONS
  623. 620
  624. 621 How to Apply These Terms to Your New Programs
  625. 622
  626. 623 If you develop a new program, and you want it to be of the greatest
  627. 624 possible use to the public, the best way to achieve this is to make it
  628. 625 free software which everyone can redistribute and change under these terms.
  629. 626
  630. 627 To do so, attach the following notices to the program. It is safest
  631. 628 to attach them to the start of each source file to most effectively
  632. 629 state the exclusion of warranty; and each file should have at least
  633. 630 the "copyright" line and a pointer to where the full notice is found.
  634. 631
  635. 632 TRAINBLOCKS: It adds some signs for the advtrains mod.
  636. 633 Copyright (C) 2018 maxx, gpcf
  637. 634
  638. 635 This program is free software: you can redistribute it and/or modify
  639. 636 it under the terms of the GNU Affero General Public License as published by
  640. 637 the Free Software Foundation, either version 3 of the License, or
  641. 638 (at your option) any later version.
  642. 639
  643. 640 This program is distributed in the hope that it will be useful,
  644. 641 but WITHOUT ANY WARRANTY; without even the implied warranty of
  645. 642 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
  646. 643 GNU Affero General Public License for more details.
  647. 644
  648. 645 You should have received a copy of the GNU Affero General Public License
  649. 646 along with this program. If not, see <https://www.gnu.org/licenses/>.
  650. 647
  651. 648 Also add information on how to contact you by electronic and paper mail.
  652. 649
  653. 650 If your software can interact with users remotely through a computer
  654. 651 network, you should also make sure that it provides a way for users to
  655. 652 get its source. For example, if your program is a web application, its
  656. 653 interface could display a "Source" link that leads users to an archive
  657. 654 of the code. There are many ways you could offer source, and different
  658. 655 solutions will be better for different programs; see section 13 for the
  659. 656 specific requirements.
  660. 657
  661. 658 You should also get your employer (if you work as a programmer) or school,
  662. 659 if any, to sign a "copyright disclaimer" for the program, if necessary.
