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

If not, see <https://www.gnu.org/licenses/>. 649 + 650 +Also add information on how to contact you by electronic and paper 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 appropriate 661 +parts of the General Public License. Of course, your program's commands 662 +might be different; for a GUI interface, you would use an "about box". 663 + 664 + You should also get your employer (if you work as a programmer) or school, 665 +if any, to sign a "copyright disclaimer" for the program, if necessary. 666 +For more information on this, and how to apply and follow the GNU GPL, see 667 +<https://www.gnu.org/licenses/>. 668 + 669 + The GNU General Public License does not permit incorporating your program 670 +into proprietary programs. If your program is a subroutine library, you 671 +may consider it more useful to permit linking proprietary applications with 672 +the library. If this is what you want to do, use the GNU Lesser General 673 +Public License instead of this License. But first, please read 674 +<https://www.gnu.org/licenses/why-not-lgpl.html>.
