1 2 © 2014-2020 Christoph Lohmann <20h at r-36 dot net> 3 © 2020 Anders Damsgaard <email@example.com> 4 5 GNU GENERAL PUBLIC LICENSE 6 Version 3, 29 June 2007 7 8 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 9 Everyone is permitted to copy and distribute verbatim copies 10 of this license document, but changing it is not allowed. 11 12 Preamble 13 14 The GNU General Public License is a free, copyleft license for 15 software and other kinds of works. 16 17 The licenses for most software and other practical works are designed 18 to take away your freedom to share and change the works. By contrast, 19 the GNU General Public License is intended to guarantee your freedom to 20 share and change all versions of a program--to make sure it remains free 21 software for all its users. We, the Free Software Foundation, use the 22 GNU General Public License for most of our software; it applies also to 23 any other work released this way by its authors. You can apply it to 24 your programs, too. 25 26 When we speak of free software, we are referring to freedom, not 27 price. Our General Public Licenses are designed to make sure that you 28 have the freedom to distribute copies of free software (and charge for 29 them if you wish), that you receive source code or can get it if you 30 want it, that you can change the software or use pieces of it in new 31 free programs, and that you know you can do these things. 32 33 To protect your rights, we need to prevent others from denying you 34 these rights or asking you to surrender the rights. Therefore, you have 35 certain responsibilities if you distribute copies of the software, or if 36 you modify it: responsibilities to respect the freedom 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 manufacturer 56 can do so. This is fundamentally incompatible with the aim of 57 protecting users' freedom to change the software. The systematic 58 pattern of such abuse occurs in the area of products for individuals to 59 use, which is precisely where it is most unacceptable. Therefore, we 60 have designed this version of the GPL to prohibit the practice for those 61 products. If such problems arise substantially in other domains, we 62 stand ready to extend this provision to those domains in future versions 63 of the GPL, as needed to protect the freedom of users. 64 65 Finally, every program is threatened constantly by software patents. 66 States should not allow patents to restrict development and use of 67 software on general-purpose computers, but in those that do, we wish to 68 avoid the special danger that patents applied to a free program could 69 make it effectively proprietary. To prevent this, the GPL assures that 70 patents cannot be used to render the program non-free. 71 72 The precise terms and conditions for copying, distribution and 73 modification follow. 74 75 TERMS AND CONDITIONS 76 77 0. Definitions. 78 79 "This License" refers to version 3 of the GNU General Public License. 80 81 "Copyright" also means copyright-like laws that apply to other kinds of 82 works, such as semiconductor masks. 83 84 "The Program" refers to any copyrightable work licensed under this 85 License. Each licensee is addressed as "you". "Licensees" and 86 "recipients" may be individuals or organizations. 87 88 To "modify" a work means to copy from or adapt all or part of the work 89 in a fashion requiring copyright permission, other than the making of an 90 exact copy. The resulting work is called a "modified version" of the 91 earlier work or a work "based on" the earlier work. 92 93 A "covered work" means either the unmodified Program or a work based 94 on the Program. 95 96 To "propagate" a work means to do anything with it that, without 97 permission, would make you directly or secondarily liable for 98 infringement under applicable copyright law, except executing it on a 99 computer or modifying a private copy. Propagation includes copying, 100 distribution (with or without modification), making available to the 101 public, and in some countries other activities as well. 102 103 To "convey" a work means any kind of propagation that enables other 104 parties to make or receive copies. Mere interaction with a user through 105 a computer network, with no transfer of a copy, is not conveying. 106 107 An interactive user interface displays "Appropriate Legal Notices" 108 to the extent that it includes a convenient and prominently visible 109 feature that (1) displays an appropriate copyright notice, and (2) 110 tells the user that there is no warranty for the work (except to the 111 extent that warranties are provided), that licensees may convey the 112 work under this License, and how to view a copy of this License. If 113 the interface presents a list of user commands or options, such as a 114 menu, a prominent item in the list meets this criterion. 115 116 1. Source Code. 117 118 The "source code" for a work means the preferred form of the work 119 for making modifications to it. "Object code" means any non-source 120 form of a work. 121 122 A "Standard Interface" means an interface that either is an official 123 standard defined by a recognized standards body, or, in the case of 124 interfaces specified for a particular programming language, one that 125 is widely used among developers working in that language. 126 127 The "System Libraries" of an executable work include anything, other 128 than the work as a whole, that (a) is included in the normal form of 129 packaging a Major Component, but which is not part of that Major 130 Component, and (b) serves only to enable use of the work with that 131 Major Component, or to implement a Standard Interface for which an 132 implementation is available to the public in source code form. A 133 "Major Component", in this context, means a major essential component 134 (kernel, window system, and so on) of the specific operating system 135 (if any) on which the executable work runs, or a compiler used to 136 produce the work, or an object code interpreter used to run it. 137 138 The "Corresponding Source" for a work in object code form means all 139 the source code needed to generate, install, and (for an executable 140 work) run the object code and to modify the work, including scripts to 141 control those activities. However, it does not include the work's 142 System Libraries, or general-purpose tools or generally available free 143 programs which are used unmodified in performing those activities but 144 which are not part of the work. For example, Corresponding Source 145 includes interface definition files associated with source files for 146 the work, and the source code for shared libraries and dynamically 147 linked subprograms that the work is specifically designed to require, 148 such as by intimate data communication or control flow between those 149 subprograms and other parts of the work. 150 151 The Corresponding Source need not include anything that users 152 can regenerate automatically from other parts of the Corresponding 153 Source. 154 155 The Corresponding Source for a work in source code form is that 156 same work. 157 158 2. Basic Permissions. 159 160 All rights granted under this License are granted for the term of 161 copyright on the Program, and are irrevocable provided the stated 162 conditions are met. This License explicitly affirms your unlimited 163 permission to run the unmodified Program. The output from running a 164 covered work is covered by this License only if the output, given its 165 content, constitutes a covered work. This License acknowledges your 166 rights of fair use or other equivalent, as provided by copyright law. 167 168 You may make, run and propagate covered works that you do not 169 convey, without conditions so long as your license otherwise remains 170 in force. You may convey covered works to others for the sole purpose 171 of having them make modifications exclusively for you, or provide you 172 with facilities for running those works, provided that you comply with 173 the terms of this License in conveying all material for which you do 174 not control copyright. Those thus making or running the covered works 175 for you must do so exclusively on your behalf, under your direction 176 and control, on terms that prohibit them from making any copies of 177 your copyrighted material outside their relationship with you. 178 179 Conveying under any other circumstances is permitted solely under 180 the conditions stated below. Sublicensing is not allowed; section 10 181 makes it unnecessary. 182 183 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 184 185 No covered work shall be deemed part of an effective technological 186 measure under any applicable law fulfilling obligations under article 187 11 of the WIPO copyright treaty adopted on 20 December 1996, or 188 similar laws prohibiting or restricting circumvention of such 189 measures. 190 191 When you convey a covered work, you waive any legal power to forbid 192 circumvention of technological measures to the extent such circumvention 193 is effected by exercising rights under this License with respect to 194 the covered work, and you disclaim any intention to limit operation or 195 modification of the work as a means of enforcing, against the work's 196 users, your or third parties' legal rights to forbid circumvention of 197 technological measures. 198 199 4. Conveying Verbatim Copies. 200 201 You may convey verbatim copies of the Program's source code as you 202 receive it, in any medium, provided that you conspicuously and 203 appropriately publish on each copy an appropriate copyright notice; 204 keep intact all notices stating that this License and any 205 non-permissive terms added in accord with section 7 apply to the code; 206 keep intact all notices of the absence of any warranty; and give all 207 recipients a copy of this License along with the Program. 208 209 You may charge any price or no price for each copy that you convey, 210 and you may offer support or warranty protection for a fee. 211 212 5. Conveying Modified Source Versions. 213 214 You may convey a work based on the Program, or the modifications to 215 produce it from the Program, in the form of source code under the 216 terms of section 4, provided that you also meet all of these conditions: 217 218 a) The work must carry prominent notices stating that you modified 219 it, and giving a relevant date. 220 221 b) The work must carry prominent notices stating that it is 222 released under this License and any conditions added under section 223 7. This requirement modifies the requirement in section 4 to 224 "keep intact all notices". 225 226 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. 233 234 d) If the work has interactive user interfaces, each must display 235 Appropriate Legal Notices; however, if the Program has interactive 236 interfaces that do not display Appropriate Legal Notices, your 237 work need not make them do so. 238 239 A compilation of a covered work with other separate and independent 240 works, which are not by their nature extensions of the covered work, 241 and which are not combined with it such as to form a larger program, 242 in or on a volume of a storage or distribution medium, is called an 243 "aggregate" if the compilation and its resulting copyright are not 244 used to limit the access or legal rights of the compilation's users 245 beyond what the individual works permit. Inclusion of a covered work 246 in an aggregate does not cause this License to apply to the other 247 parts of the aggregate. 248 249 6. Conveying Non-Source Forms. 250 251 You may convey a covered work in object code form under the terms 252 of sections 4 and 5, provided that you also convey the 253 machine-readable Corresponding Source under the terms of this License, 254 in one of these ways: 255 256 a) Convey the object code in, or embodied in, a physical product 257 (including a physical distribution medium), accompanied by the 258 Corresponding Source fixed on a durable physical medium 259 customarily used for software interchange. 260 261 b) Convey the object code in, or embodied in, a physical product 262 (including a physical distribution medium), accompanied by a 263 written offer, valid for at least three years and valid for as 264 long as you offer spare parts or customer support for that product 265 model, to give anyone who possesses the object code either (1) a 266 copy of the Corresponding Source for all the software in the 267 product that is covered by this License, on a durable physical 268 medium customarily used for software interchange, for a price no 269 more than your reasonable cost of physically performing this 270 conveying of source, or (2) access to copy the 271 Corresponding Source from a network server at no charge. 272 273 c) Convey individual copies of the object code with a copy of the 274 written offer to provide the Corresponding Source. This 275 alternative is allowed only occasionally and noncommercially, and 276 only if you received the object code with such an offer, in accord 277 with subsection 6b. 278 279 d) Convey the object code by offering access from a designated 280 place (gratis or for a charge), and offer equivalent access to the 281 Corresponding Source in the same way through the same place at no 282 further charge. You need not require recipients to copy the 283 Corresponding Source along with the object code. If the place to 284 copy the object code is a network server, the Corresponding Source 285 may be on a different server (operated by you or a third party) 286 that supports equivalent copying facilities, provided you maintain 287 clear directions next to the object code saying where to find the 288 Corresponding Source. Regardless of what server hosts the 289 Corresponding Source, you remain obligated to ensure that it is 290 available for as long as needed to satisfy these requirements. 291 292 e) Convey the object code using peer-to-peer transmission, provided 293 you inform other peers where the object code and Corresponding 294 Source of the work are being offered to the general public at no 295 charge under subsection 6d. 296 297 A separable portion of the object code, whose source code is excluded 298 from the Corresponding Source as a System Library, need not be 299 included in conveying the object code work. 300 301 A "User Product" is either (1) a "consumer product", which means any 302 tangible personal property which is normally used for personal, family, 303 or household purposes, or (2) anything designed or sold for incorporation 304 into a dwelling. In determining whether a product is a consumer product, 305 doubtful cases shall be resolved in favor of coverage. For a particular 306 product received by a particular user, "normally used" refers to a 307 typical or common use of that class of product, regardless of the status 308 of the particular user or of the way in which the particular user 309 actually uses, or expects or is expected to use, the product. A product 310 is a consumer product regardless of whether the product has substantial 311 commercial, industrial or non-consumer uses, unless such uses represent 312 the only significant mode of use of the product. 313 314 "Installation Information" for a User Product means any methods, 315 procedures, authorization keys, or other information required to install 316 and execute modified versions of a covered work in that User Product from 317 a modified version of its Corresponding Source. The information must 318 suffice to ensure that the continued functioning of the modified object 319 code is in no case prevented or interfered with solely because 320 modification has been made. 321 322 If you convey an object code work under this section in, or with, or 323 specifically for use in, a User Product, and the conveying occurs as 324 part of a transaction in which the right of possession and use of the 325 User Product is transferred to the recipient in perpetuity or for a 326 fixed term (regardless of how the transaction is characterized), the 327 Corresponding Source conveyed under this section must be accompanied 328 by the Installation Information. But this requirement does not apply 329 if neither you nor any third party retains the ability to install 330 modified object code on the User Product (for example, the work has 331 been installed in ROM). 332 333 The requirement to provide Installation Information does not include a 334 requirement to continue to provide support service, warranty, or updates 335 for a work that has been modified or installed by the recipient, or for 336 the User Product in which it has been modified or installed. Access to a 337 network may be denied when the modification itself materially and 338 adversely affects the operation of the network or violates the rules and 339 protocols for communication across the network. 340 341 Corresponding Source conveyed, and Installation Information provided, 342 in accord with this section must be in a format that is publicly 343 documented (and with an implementation available to the public in 344 source code form), and must require no special password or key for 345 unpacking, reading or copying. 346 347 7. Additional Terms. 348 349 "Additional permissions" are terms that supplement the terms of this 350 License by making exceptions from one or more of its conditions. 351 Additional permissions that are applicable to the entire Program shall 352 be treated as though they were included in this License, to the extent 353 that they are valid under applicable law. If additional permissions 354 apply only to part of the Program, that part may be used separately 355 under those permissions, but the entire Program remains governed by 356 this License without regard to the additional permissions. 357 358 When you convey a copy of a covered work, you may at your option 359 remove any additional permissions from that copy, or from any part of 360 it. (Additional permissions may be written to require their own 361 removal in certain cases when you modify the work.) You may place 362 additional permissions on material, added by you to a covered work, 363 for which you have or can give appropriate copyright permission. 364 365 Notwithstanding any other provision of this License, for material you 366 add to a covered work, you may (if authorized by the copyright holders of 367 that material) supplement the terms of this License with terms: 368 369 a) Disclaiming warranty or limiting liability differently from the 370 terms of sections 15 and 16 of this License; or 371 372 b) Requiring preservation of specified reasonable legal notices or 373 author attributions in that material or in the Appropriate Legal 374 Notices displayed by works containing it; or 375 376 c) Prohibiting misrepresentation of the origin of that material, or 377 requiring that modified versions of such material be marked in 378 reasonable ways as different from the original version; or 379 380 d) Limiting the use for publicity purposes of names of licensors or 381 authors of the material; or 382 383 e) Declining to grant rights under trademark law for use of some 384 trade names, trademarks, or service marks; or 385 386 f) Requiring indemnification of licensors and authors of that 387 material by anyone who conveys the material (or modified versions of 388 it) with contractual assumptions of liability to the recipient, for 389 any liability that these contractual assumptions directly impose on 390 those licensors and authors. 391 392 All other non-permissive additional terms are considered "further 393 restrictions" within the meaning of section 10. If the Program as you 394 received it, or any part of it, contains a notice stating that it is 395 governed by this License along with a term that is a further 396 restriction, you may remove that term. If a license document contains 397 a further restriction but permits relicensing or conveying under this 398 License, you may add to a covered work material governed by the terms 399 of that license document, provided that the further restriction does 400 not survive such relicensing or conveying. 401 402 If you add terms to a covered work in accord with this section, you 403 must place, in the relevant source files, a statement of the 404 additional terms that apply to those files, or a notice indicating 405 where to find the applicable terms. 406 407 Additional terms, permissive or non-permissive, may be stated in the 408 form of a separately written license, or stated as exceptions; 409 the above requirements apply either way. 410 411 8. Termination. 412 413 You may not propagate or modify a covered work except as expressly 414 provided under this License. Any attempt otherwise to propagate or 415 modify it is void, and will automatically terminate your rights under 416 this License (including any patent licenses granted under the third 417 paragraph of section 11). 418 419 However, if you cease all violation of this License, then your 420 license from a particular copyright holder is reinstated (a) 421 provisionally, unless and until the copyright holder explicitly and 422 finally terminates your license, and (b) permanently, if the copyright 423 holder fails to notify you of the violation by some reasonable means 424 prior to 60 days after the cessation. 425 426 Moreover, your license from a particular copyright holder is 427 reinstated permanently if the copyright holder notifies you of the 428 violation by some reasonable means, this is the first time you have 429 received notice of violation of this License (for any work) from that 430 copyright holder, and you cure the violation prior to 30 days after 431 your receipt of the notice. 432 433 Termination of your rights under this section does not terminate the 434 licenses of parties who have received copies or rights from you under 435 this License. If your rights have been terminated and not permanently 436 reinstated, you do not qualify to receive new licenses for the same 437 material under section 10. 438 439 9. Acceptance Not Required for Having Copies. 440 441 You are not required to accept this License in order to receive or 442 run a copy of the Program. Ancillary propagation of a covered work 443 occurring solely as a consequence of using peer-to-peer transmission 444 to receive a copy likewise does not require acceptance. However, 445 nothing other than this License grants you permission to propagate or 446 modify any covered work. These actions infringe copyright if you do 447 not accept this License. Therefore, by modifying or propagating a 448 covered work, you indicate your acceptance of this License to do so. 449 450 10. Automatic Licensing of Downstream Recipients. 451 452 Each time you convey a covered work, the recipient automatically 453 receives a license from the original licensors, to run, modify and 454 propagate that work, subject to this License. You are not responsible 455 for enforcing compliance by third parties with this License. 456 457 An "entity transaction" is a transaction transferring control of an 458 organization, or substantially all assets of one, or subdividing an 459 organization, or merging organizations. If propagation of a covered 460 work results from an entity transaction, each party to that 461 transaction who receives a copy of the work also receives whatever 462 licenses to the work the party's predecessor in interest had or could 463 give under the previous paragraph, plus a right to possession of the 464 Corresponding Source of the work from the predecessor in interest, if 465 the predecessor has it or can get it with reasonable efforts. 466 467 You may not impose any further restrictions on the exercise of the 468 rights granted or affirmed under this License. For example, you may 469 not impose a license fee, royalty, or other charge for exercise of 470 rights granted under this License, and you may not initiate litigation 471 (including a cross-claim or counterclaim in a lawsuit) alleging that 472 any patent claim is infringed by making, using, selling, offering for 473 sale, or importing the Program or any portion of it. 474 475 11. Patents. 476 477 A "contributor" is a copyright holder who authorizes use under this 478 License of the Program or a work on which the Program is based. The 479 work thus licensed is called the contributor's "contributor version". 480 481 A contributor's "essential patent claims" are all patent claims 482 owned or controlled by the contributor, whether already acquired or 483 hereafter acquired, that would be infringed by some manner, permitted 484 by this License, of making, using, or selling its contributor version, 485 but do not include claims that would be infringed only as a 486 consequence of further modification of the contributor version. For 487 purposes of this definition, "control" includes the right to grant 488 patent sublicenses in a manner consistent with the requirements of 489 this License. 490 491 Each contributor grants you a non-exclusive, worldwide, royalty-free 492 patent license under the contributor's essential patent claims, to 493 make, use, sell, offer for sale, import and otherwise run, modify and 494 propagate the contents of its contributor version. 495 496 In the following three paragraphs, a "patent license" is any express 497 agreement or commitment, however denominated, not to enforce a patent 498 (such as an express permission to practice a patent or covenant not to 499 sue for patent infringement). To "grant" such a patent license to a 500 party means to make such an agreement or commitment not to enforce a 501 patent against the party. 502 503 If you convey a covered work, knowingly relying on a patent license, 504 and the Corresponding Source of the work is not available for anyone 505 to copy, free of charge and under the terms of this License, through a 506 publicly available network server or other readily accessible means, 507 then you must either (1) cause the Corresponding Source to be so 508 available, or (2) arrange to deprive yourself of the benefit of the 509 patent license for this particular work, or (3) arrange, in a manner 510 consistent with the requirements of this License, to extend the patent 511 license to downstream recipients. "Knowingly relying" means you have 512 actual knowledge that, but for the patent license, your conveying the 513 covered work in a country, or your recipient's use of the covered work 514 in a country, would infringe one or more identifiable patents in that 515 country that you have reason to believe are valid. 516 517 If, pursuant to or in connection with a single transaction or 518 arrangement, you convey, or propagate by procuring conveyance of, a 519 covered work, and grant a patent license to some of the parties 520 receiving the covered work authorizing them to use, propagate, modify 521 or convey a specific copy of the covered work, then the patent license 522 you grant is automatically extended to all recipients of the covered 523 work and works based on it. 524 525 A patent license is "discriminatory" if it does not include within 526 the scope of its coverage, prohibits the exercise of, or is 527 conditioned on the non-exercise of one or more of the rights that are 528 specifically granted under this License. You may not convey a covered 529 work if you are a party to an arrangement with a third party that is 530 in the business of distributing software, under which you make payment 531 to the third party based on the extent of your activity of conveying 532 the work, and under which the third party grants, to any of the 533 parties who would receive the covered work from you, a discriminatory 534 patent license (a) in connection with copies of the covered work 535 conveyed by you (or copies made from those copies), or (b) primarily 536 for and in connection with specific products or compilations that 537 contain the covered work, unless you entered into that arrangement, 538 or that patent license was granted, prior to 28 March 2007. 539 540 Nothing in this License shall be construed as excluding or limiting 541 any implied license or other defenses to infringement that may 542 otherwise be available to you under applicable patent law. 543 544 12. No Surrender of Others' Freedom. 545 546 If conditions are imposed on you (whether by court order, agreement or 547 otherwise) that contradict the conditions of this License, they do not 548 excuse you from the conditions of this License. If you cannot convey a 549 covered work so as to satisfy simultaneously your obligations under this 550 License and any other pertinent obligations, then as a consequence you may 551 not convey it at all. For example, if you agree to terms that obligate you 552 to collect a royalty for further conveying from those to whom you convey 553 the Program, the only way you could satisfy both those terms and this 554 License would be to refrain entirely from conveying the Program. 555 556 13. Use with the GNU Affero General Public License. 557 558 Notwithstanding any other provision of this License, you have 559 permission to link or combine any covered work with a work licensed 560 under version 3 of the GNU Affero General Public License into a single 561 combined work, and to convey the resulting work. The terms of this 562 License will continue to apply to the part which is the covered work, 563 but the special requirements of the GNU Affero General Public License, 564 section 13, concerning interaction through a network will apply to the 565 combination as such. 566 567 14. Revised Versions of this License. 568 569 The Free Software Foundation may publish revised and/or new versions of 570 the GNU General Public License from time to time. Such new versions will 571 be similar in spirit to the present version, but may differ in detail to 572 address new problems or concerns. 573 574 Each version is given a distinguishing version number. If the 575 Program specifies that a certain numbered version of the GNU General 576 Public License "or any later version" applies to it, you have the 577 option of following the terms and conditions either of that numbered 578 version or of any later version published by the Free Software 579 Foundation. If the Program does not specify a version number of the 580 GNU General Public License, you may choose any version ever published 581 by the Free Software Foundation. 582 583 If the Program specifies that a proxy can decide which future 584 versions of the GNU General Public License can be used, that proxy's 585 public statement of acceptance of a version permanently authorizes you 586 to choose that version for the Program. 587 588 Later license versions may give you additional or different 589 permissions. However, no additional obligations are imposed on any 590 author or copyright holder as a result of your choosing to follow a 591 later version. 592 593 15. Disclaimer of Warranty. 594 595 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 596 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 597 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 598 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 599 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 600 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 601 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 602 ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 603 604 16. Limitation of Liability. 605 606 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 607 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 608 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 609 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 610 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 611 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 612 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 613 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 614 SUCH DAMAGES. 615 616 17. Interpretation of Sections 15 and 16. 617 618 If the disclaimer of warranty and limitation of liability provided 619 above cannot be given local legal effect according to their terms, 620 reviewing courts shall apply local law that most closely approximates 621 an absolute waiver of all civil liability in connection with the 622 Program, unless a warranty or assumption of liability accompanies a 623 copy of the Program in return for a fee. 624 625 END OF TERMS AND CONDITIONS 626 627 How to Apply These Terms to Your New Programs 628 629 If you develop a new program, and you want it to be of the greatest 630 possible use to the public, the best way to achieve this is to make it 631 free software which everyone can redistribute and change under these terms. 632 633 To do so, attach the following notices to the program. It is safest 634 to attach them to the start of each source file to most effectively 635 state the exclusion of warranty; and each file should have at least 636 the "copyright" line and a pointer to where the full notice is found. 637 638 <one line to give the program's name and a brief idea of what it does.> 639 Copyright (C) <year> <name of author> 640 641 This program is free software: you can redistribute it and/or modify 642 it under the terms of the GNU General Public License as published by 643 the Free Software Foundation, either version 3 of the License, or 644 (at your option) any later version. 645 646 This program is distributed in the hope that it will be useful, 647 but WITHOUT ANY WARRANTY; without even the implied warranty of 648 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 649 GNU General Public License for more details. 650 651 You should have received a copy of the GNU General Public License 652 along with this program. If not, see <http://www.gnu.org/licenses/>. 653 654 Also add information on how to contact you by electronic and paper mail. 655 656 If the program does terminal interaction, make it output a short 657 notice like this when it starts in an interactive mode: 658 659 <program> Copyright (C) <year> <name of author> 660 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 661 This is free software, and you are welcome to redistribute it 662 under certain conditions; type `show c' for details. 663 664 The hypothetical commands `show w' and `show c' should show the appropriate 665 parts of the General Public License. Of course, your program's commands 666 might be different; for a GUI interface, you would use an "about box". 667 668 You should also get your employer (if you work as a programmer) or school, 669 if any, to sign a "copyright disclaimer" for the program, if necessary. 670 For more information on this, and how to apply and follow the GNU GPL, see 671 <http://www.gnu.org/licenses/>. 672 673 The GNU General Public License does not permit incorporating your program 674 into proprietary programs. If your program is a subroutine library, you 675 may consider it more useful to permit linking proprietary applications with 676 the library. If this is what you want to do, use the GNU Lesser General 677 Public License instead of this License. But first, please read 678 <http://www.gnu.org/philosophy/why-not-lgpl.html>.
