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