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