By contrast, 13 | the GNU General Public License is intended to guarantee your freedom to 14 | share and change all versions of a program--to make sure it remains free 15 | software for all its users. We, the Free Software Foundation, use the 16 | GNU General Public License for most of our software; it applies also to 17 | any other work released this way by its authors. You can apply it to 18 | your programs, too. 19 | 20 | When we speak of free software, we are referring to freedom, not 21 | price. Our General Public Licenses are designed to make sure that you 22 | have the freedom to distribute copies of free software (and charge for 23 | them if you wish), that you receive source code or can get it if you 24 | want it, that you can change the software or use pieces of it in new 25 | free programs, and that you know you can do these things. 26 | 27 | To protect your rights, we need to prevent others from denying you 28 | these rights or asking you to surrender the rights. Therefore, you have 29 | certain responsibilities if you distribute copies of the software, or if 30 | you modify it: responsibilities to respect the freedom of others. 31 | 32 | For example, if you distribute copies of such a program, whether 33 | gratis or for a fee, you must pass on to the recipients the same 34 | freedoms that you received. You must make sure that they, too, receive 35 | or can get the source code. And you must show them these terms so they 36 | know their rights. 37 | 38 | Developers that use the GNU GPL protect your rights with two steps: 39 | (1) assert copyright on the software, and (2) offer you this License 40 | giving you legal permission to copy, distribute and/or modify it. 41 | 42 | For the developers' and authors' protection, the GPL clearly explains 43 | that there is no warranty for this free software. For both users' and 44 | authors' sake, the GPL requires that modified versions be marked as 45 | changed, so that their problems will not be attributed erroneously to 46 | authors of previous versions. 47 | 48 | Some devices are designed to deny users access to install or run 49 | modified versions of the software inside them, although the manufacturer 50 | can do so. This is fundamentally incompatible with the aim of 51 | protecting users' freedom to change the software. The systematic 52 | 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 54 | have designed this version of the GPL to prohibit the practice for those 55 | products. If such problems arise substantially in other domains, we 56 | stand ready to extend this provision to those domains in future versions 57 | of the GPL, as needed to protect the freedom of users. 58 | 59 | Finally, every program is threatened constantly by software patents. 60 | States should not allow patents to restrict development and use of 61 | software on general-purpose computers, but in those that do, we wish to 62 | avoid the special danger that patents applied to a free program could 63 | make it effectively proprietary. To prevent this, the GPL assures that 64 | patents cannot be used to render the program non-free. 65 | 66 | The precise terms and conditions for copying, distribution and 67 | modification follow. 68 | 69 | TERMS AND CONDITIONS 70 | 71 | 0. Definitions. 72 | 73 | "This License" refers to version 3 of the GNU General Public License. 74 | 75 | "Copyright" also means copyright-like laws that apply to other kinds of 76 | works, such as semiconductor masks. 77 | 78 | "The Program" refers to any copyrightable work licensed under this 79 | License. Each licensee is addressed as "you". "Licensees" and 80 | "recipients" may be individuals or organizations. 81 | 82 | To "modify" a work means to copy from or adapt all or part of the work 83 | in a fashion requiring copyright permission, other than the making of an 84 | exact copy. The resulting work is called a "modified version" of the 85 | earlier work or a work "based on" the earlier work. 86 | 87 | A "covered work" means either the unmodified Program or a work based 88 | on the Program. 89 | 90 | To "propagate" a work means to do anything with it that, without 91 | permission, would make you directly or secondarily liable for 92 | infringement under applicable copyright law, except executing it on a 93 | computer or modifying a private copy. Propagation includes copying, 94 | distribution (with or without modification), making available to the 95 | public, and in some countries other activities as well. 96 | 97 | To "convey" a work means any kind of propagation that enables other 98 | parties to make or receive copies. Mere interaction with a user through 99 | a computer network, with no transfer of a copy, is not conveying. 100 | 101 | An interactive user interface displays "Appropriate Legal Notices" 102 | to the extent that it includes a convenient and prominently visible 103 | feature that (1) displays an appropriate copyright notice, and (2) 104 | tells the user that there is no warranty for the work (except to the 105 | extent that warranties are provided), that licensees may convey the 106 | work under this License, and how to view a copy of this License. If 107 | the interface presents a list of user commands or options, such as a 108 | menu, a prominent item in the list meets this criterion. 109 | 110 | 1. Source Code. 111 | 112 | The "source code" for a work means the preferred form of the work 113 | for making modifications to it. "Object code" means any non-source 114 | form of a work. 115 | 116 | A "Standard Interface" means an interface that either is an official 117 | standard defined by a recognized standards body, or, in the case of 118 | interfaces specified for a particular programming language, one that 119 | is widely used among developers working in that language. 120 | 121 | The "System Libraries" of an executable work include anything, other 122 | than the work as a whole, that (a) is included in the normal form of 123 | packaging a Major Component, but which is not part of that Major 124 | Component, and (b) serves only to enable use of the work with that 125 | Major Component, or to implement a Standard Interface for which an 126 | implementation is available to the public in source code form. A 127 | "Major Component", in this context, means a major essential component 128 | (kernel, window system, and so on) of the specific operating system 129 | (if any) on which the executable work runs, or a compiler used to 130 | produce the work, or an object code interpreter used to run it. 131 | 132 | The "Corresponding Source" for a work in object code form means all 133 | the source code needed to generate, install, and (for an executable 134 | work) run the object code and to modify the work, including scripts to 135 | control those activities. However, it does not include the work's 136 | System Libraries, or general-purpose tools or generally available free 137 | programs which are used unmodified in performing those activities but 138 | which are not part of the work. For example, Corresponding Source 139 | includes interface definition files associated with source files for 140 | the work, and the source code for shared libraries and dynamically 141 | linked subprograms that the work is specifically designed to require, 142 | such as by intimate data communication or control flow between those 143 | subprograms and other parts of the work. 144 | 145 | The Corresponding Source need not include anything that users 146 | can regenerate automatically from other parts of the Corresponding 147 | Source. 148 | 149 | The Corresponding Source for a work in source code form is that 150 | same work. 151 | 152 | 2. Basic Permissions. 153 | 154 | All rights granted under this License are granted for the term of 155 | copyright on the Program, and are irrevocable provided the stated 156 | conditions are met. This License explicitly affirms your unlimited 157 | permission to run the unmodified Program. The output from running a 158 | covered work is covered by this License only if the output, given its 159 | content, constitutes a covered work. This License acknowledges your 160 | rights of fair use or other equivalent, as provided by copyright law. 161 | 162 | You may make, run and propagate covered works that you do not 163 | convey, without conditions so long as your license otherwise remains 164 | in force. You may convey covered works to others for the sole purpose 165 | of having them make modifications exclusively for you, or provide you 166 | with facilities for running those works, provided that you comply with 167 | the terms of this License in conveying all material for which you do 168 | not control copyright. Those thus making or running the covered works 169 | for you must do so exclusively on your behalf, under your direction 170 | and control, on terms that prohibit them from making any copies of 171 | your copyrighted material outside their relationship with you. 172 | 173 | Conveying under any other circumstances is permitted solely under 174 | the conditions stated below. Sublicensing is not allowed; section 10 175 | makes it unnecessary. 176 | 177 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 178 | 179 | No covered work shall be deemed part of an effective technological 180 | measure under any applicable law fulfilling obligations under article 181 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 182 | similar laws prohibiting or restricting circumvention of such 183 | measures. 184 | 185 | When you convey a covered work, you waive any legal power to forbid 186 | circumvention of technological measures to the extent such circumvention 187 | is effected by exercising rights under this License with respect to 188 | the covered work, and you disclaim any intention to limit operation or 189 | modification of the work as a means of enforcing, against the work's 190 | users, your or third parties' legal rights to forbid circumvention of 191 | technological measures. 192 | 193 | 4. Conveying Verbatim Copies. 194 | 195 | You may convey verbatim copies of the Program's source code as you 196 | receive it, in any medium, provided that you conspicuously and 197 | appropriately publish on each copy an appropriate copyright notice; 198 | keep intact all notices stating that this License and any 199 | non-permissive terms added in accord with section 7 apply to the code; 200 | keep intact all notices of the absence of any warranty; and give all 201 | recipients a copy of this License along with the Program. 202 | 203 | You may charge any price or no price for each copy that you convey, 204 | and you may offer support or warranty protection for a fee. 205 | 206 | 5. Conveying Modified Source Versions. 207 | 208 | You may convey a work based on the Program, or the modifications to 209 | produce it from the Program, in the form of source code under the 210 | terms of section 4, provided that you also meet all of these conditions: 211 | 212 | a) The work must carry prominent notices stating that you modified 213 | it, and giving a relevant date. 214 | 215 | b) The work must carry prominent notices stating that it is 216 | released under this License and any conditions added under section 217 | 7. This requirement modifies the requirement in section 4 to 218 | "keep intact all notices". 219 | 220 | c) You must license the entire work, as a whole, under this 221 | License to anyone who comes into possession of a copy. This 222 | License will therefore apply, along with any applicable section 7 223 | additional terms, to the whole of the work, and all its parts, 224 | regardless of how they are packaged. This License gives no 225 | permission to license the work in any other way, but it does not 226 | invalidate such permission if you have separately received it. 227 | 228 | d) If the work has interactive user interfaces, each must display 229 | Appropriate Legal Notices; however, if the Program has interactive 230 | interfaces that do not display Appropriate Legal Notices, your 231 | work need not make them do so. 232 | 233 | A compilation of a covered work with other separate and independent 234 | works, which are not by their nature extensions of the covered work, 235 | and which are not combined with it such as to form a larger program, 236 | in or on a volume of a storage or distribution medium, is called an 237 | "aggregate" if the compilation and its resulting copyright are not 238 | used to limit the access or legal rights of the compilation's users 239 | beyond what the individual works permit. Inclusion of a covered work 240 | in an aggregate does not cause this License to apply to the other 241 | parts of the aggregate. 242 | 243 | 6. Conveying Non-Source Forms. 244 | 245 | You may convey a covered work in object code form under the terms 246 | of sections 4 and 5, provided that you also convey the 247 | machine-readable Corresponding Source under the terms of this License, 248 | in one of these ways: 249 | 250 | a) Convey the object code in, or embodied in, a physical product 251 | (including a physical distribution medium), accompanied by the 252 | Corresponding Source fixed on a durable physical medium 253 | customarily used for software interchange. 254 | 255 | b) Convey the object code in, or embodied in, a physical product 256 | (including a physical distribution medium), accompanied by a 257 | written offer, valid for at least three years and valid for as 258 | long as you offer spare parts or customer support for that product 259 | model, to give anyone who possesses the object code either (1) a 260 | copy of the Corresponding Source for all the software in the 261 | product that is covered by this License, on a durable physical 262 | medium customarily used for software interchange, for a price no 263 | more than your reasonable cost of physically performing this 264 | conveying of source, or (2) access to copy the 265 | Corresponding Source from a network server at no charge. 266 | 267 | c) Convey individual copies of the object code with a copy of the 268 | written offer to provide the Corresponding Source. This 269 | alternative is allowed only occasionally and noncommercially, and 270 | only if you received the object code with such an offer, in accord 271 | with subsection 6b. 272 | 273 | d) Convey the object code by offering access from a designated 274 | place (gratis or for a charge), and offer equivalent access to the 275 | Corresponding Source in the same way through the same place at no 276 | further charge. You need not require recipients to copy the 277 | Corresponding Source along with the object code. If the place to 278 | copy the object code is a network server, the Corresponding Source 279 | may be on a different server (operated by you or a third party) 280 | that supports equivalent copying facilities, provided you maintain 281 | clear directions next to the object code saying where to find the 282 | Corresponding Source. Regardless of what server hosts the 283 | Corresponding Source, you remain obligated to ensure that it is 284 | available for as long as needed to satisfy these requirements. 285 | 286 | e) Convey the object code using peer-to-peer transmission, provided 287 | you inform other peers where the object code and Corresponding 288 | Source of the work are being offered to the general public at no 289 | charge under subsection 6d. 290 | 291 | A separable portion of the object code, whose source code is excluded 292 | from the Corresponding Source as a System Library, need not be 293 | included in conveying the object code work. 294 | 295 | A "User Product" is either (1) a "consumer product", which means any 296 | tangible personal property which is normally used for personal, family, 297 | or household purposes, or (2) anything designed or sold for incorporation 298 | into a dwelling. In determining whether a product is a consumer product, 299 | doubtful cases shall be resolved in favor of coverage. For a particular 300 | product received by a particular user, "normally used" refers to a 301 | typical or common use of that class of product, regardless of the status 302 | of the particular user or of the way in which the particular user 303 | actually uses, or expects or is expected to use, the product. A product 304 | is a consumer product regardless of whether the product has substantial 305 | commercial, industrial or non-consumer uses, unless such uses represent 306 | the only significant mode of use of the product. 307 | 308 | "Installation Information" for a User Product means any methods, 309 | procedures, authorization keys, or other information required to install 310 | and execute modified versions of a covered work in that User Product from 311 | a modified version of its Corresponding Source. The information must 312 | suffice to ensure that the continued functioning of the modified object 313 | code is in no case prevented or interfered with solely because 314 | modification has been made. 315 | 316 | If you convey an object code work under this section in, or with, or 317 | specifically for use in, a User Product, and the conveying occurs as 318 | part of a transaction in which the right of possession and use of the 319 | User Product is transferred to the recipient in perpetuity or for a 320 | fixed term (regardless of how the transaction is characterized), the 321 | Corresponding Source conveyed under this section must be accompanied 322 | by the Installation Information. But this requirement does not apply 323 | if neither you nor any third party retains the ability to install 324 | modified object code on the User Product (for example, the work has 325 | been installed in ROM). 326 | 327 | The requirement to provide Installation Information does not include a 328 | requirement to continue to provide support service, warranty, or updates 329 | for a work that has been modified or installed by the recipient, or for 330 | the User Product in which it has been modified or installed. Access to a 331 | network may be denied when the modification itself materially and 332 | adversely affects the operation of the network or violates the rules and 333 | protocols for communication across the network. 334 | 335 | Corresponding Source conveyed, and Installation Information provided, 336 | in accord with this section must be in a format that is publicly 337 | documented (and with an implementation available to the public in 338 | source code form), and must require no special password or key for 339 | unpacking, reading or copying. 340 | 341 | 7. Additional Terms. 342 | 343 | "Additional permissions" are terms that supplement the terms of this 344 | License by making exceptions from one or more of its conditions. 345 | Additional permissions that are applicable to the entire Program shall 346 | be treated as though they were included in this License, to the extent 347 | that they are valid under applicable law. If additional permissions 348 | apply only to part of the Program, that part may be used separately 349 | under those permissions, but the entire Program remains governed by 350 | this License without regard to the additional permissions. 351 | 352 | When you convey a copy of a covered work, you may at your option 353 | remove any additional permissions from that copy, or from any part of 354 | it. (Additional permissions may be written to require their own 355 | removal in certain cases when you modify the work.) You may place 356 | additional permissions on material, added by you to a covered work, 357 | for which you have or can give appropriate copyright permission. 358 | 359 | Notwithstanding any other provision of this License, for material you 360 | add to a covered work, you may (if authorized by the copyright holders of 361 | that material) supplement the terms of this License with terms: 362 | 363 | a) Disclaiming warranty or limiting liability differently from the 364 | terms of sections 15 and 16 of this License; or 365 | 366 | b) Requiring preservation of specified reasonable legal notices or 367 | author attributions in that material or in the Appropriate Legal 368 | Notices displayed by works containing it; or 369 | 370 | c) Prohibiting misrepresentation of the origin of that material, or 371 | requiring that modified versions of such material be marked in 372 | reasonable ways as different from the original version; or 373 | 374 | d) Limiting the use for publicity purposes of names of licensors or 375 | authors of the material; or 376 | 377 | e) Declining to grant rights under trademark law for use of some 378 | trade names, trademarks, or service marks; or 379 | 380 | f) Requiring indemnification of licensors and authors of that 381 | material by anyone who conveys the material (or modified versions of 382 | it) with contractual assumptions of liability to the recipient, for 383 | any liability that these contractual assumptions directly impose on 384 | those licensors and authors. 385 | 386 | All other non-permissive additional terms are considered "further 387 | restrictions" within the meaning of section 10. If the Program as you 388 | received it, or any part of it, contains a notice stating that it is 389 | governed by this License along with a term that is a further 390 | restriction, you may remove that term. If a license document contains 391 | a further restriction but permits relicensing or conveying under this 392 | License, you may add to a covered work material governed by the terms 393 | of that license document, provided that the further restriction does 394 | not survive such relicensing or conveying. 395 | 396 | If you add terms to a covered work in accord with this section, you 397 | must place, in the relevant source files, a statement of the 398 | additional terms that apply to those files, or a notice indicating 399 | where to find the applicable terms. 400 | 401 | Additional terms, permissive or non-permissive, may be stated in the 402 | form of a separately written license, or stated as exceptions; 403 | the above requirements apply either way. 404 | 405 | 8. Termination. 406 | 407 | You may not propagate or modify a covered work except as expressly 408 | provided under this License. Any attempt otherwise to propagate or 409 | modify it is void, and will automatically terminate your rights under 410 | this License (including any patent licenses granted under the third 411 | paragraph of section 11). 412 | 413 | However, if you cease all violation of this License, then your 414 | license from a particular copyright holder is reinstated (a) 415 | provisionally, unless and until the copyright holder explicitly and 416 | finally terminates your license, and (b) permanently, if the copyright 417 | holder fails to notify you of the violation by some reasonable means 418 | prior to 60 days after the cessation. 419 | 420 | Moreover, your license from a particular copyright holder is 421 | reinstated permanently if the copyright holder notifies you of the 422 | violation by some reasonable means, this is the first time you have 423 | received notice of violation of this License (for any work) from that 424 | copyright holder, and you cure the violation prior to 30 days after 425 | your receipt of the notice. 426 | 427 | Termination of your rights under this section does not terminate the 428 | licenses of parties who have received copies or rights from you under 429 | this License. If your rights have been terminated and not permanently 430 | reinstated, you do not qualify to receive new licenses for the same 431 | material under section 10. 432 | 433 | 9. Acceptance Not Required for Having Copies. 434 | 435 | You are not required to accept this License in order to receive or 436 | run a copy of the Program. Ancillary propagation of a covered work 437 | occurring solely as a consequence of using peer-to-peer transmission 438 | to receive a copy likewise does not require acceptance. However, 439 | nothing other than this License grants you permission to propagate or 440 | modify any covered work. These actions infringe copyright if you do 441 | not accept this License. Therefore, by modifying or propagating a 442 | covered work, you indicate your acceptance of this License to do so. 443 | 444 | 10. Automatic Licensing of Downstream Recipients. 445 | 446 | Each time you convey a covered work, the recipient automatically 447 | receives a license from the original licensors, to run, modify and 448 | propagate that work, subject to this License. You are not responsible 449 | for enforcing compliance by third parties with this License. 450 | 451 | An "entity transaction" is a transaction transferring control of an 452 | organization, or substantially all assets of one, or subdividing an 453 | organization, or merging organizations. If propagation of a covered 454 | work results from an entity transaction, each party to that 455 | transaction who receives a copy of the work also receives whatever 456 | licenses to the work the party's predecessor in interest had or could 457 | give under the previous paragraph, plus a right to possession of the 458 | Corresponding Source of the work from the predecessor in interest, if 459 | the predecessor has it or can get it with reasonable efforts. 460 | 461 | You may not impose any further restrictions on the exercise of the 462 | rights granted or affirmed under this License. For example, you may 463 | not impose a license fee, royalty, or other charge for exercise of 464 | rights granted under this License, and you may not initiate litigation 465 | (including a cross-claim or counterclaim in a lawsuit) alleging that 466 | any patent claim is infringed by making, using, selling, offering for 467 | sale, or importing the Program or any portion of it. 468 | 469 | 11. Patents. 470 | 471 | A "contributor" is a copyright holder who authorizes use under this 472 | License of the Program or a work on which the Program is based. The 473 | work thus licensed is called the contributor's "contributor version". 474 | 475 | A contributor's "essential patent claims" are all patent claims 476 | owned or controlled by the contributor, whether already acquired or 477 | hereafter acquired, that would be infringed by some manner, permitted 478 | by this License, of making, using, or selling its contributor version, 479 | but do not include claims that would be infringed only as a 480 | consequence of further modification of the contributor version. For 481 | purposes of this definition, "control" includes the right to grant 482 | patent sublicenses in a manner consistent with the requirements of 483 | this License. 484 | 485 | Each contributor grants you a non-exclusive, worldwide, royalty-free 486 | patent license under the contributor's essential patent claims, to 487 | make, use, sell, offer for sale, import and otherwise run, modify and 488 | propagate the contents of its contributor version. 489 | 490 | In the following three paragraphs, a "patent license" is any express 491 | agreement or commitment, however denominated, not to enforce a patent 492 | (such as an express permission to practice a patent or covenant not to 493 | sue for patent infringement). To "grant" such a patent license to a 494 | party means to make such an agreement or commitment not to enforce a 495 | patent against the party. 496 | 497 | If you convey a covered work, knowingly relying on a patent license, 498 | and the Corresponding Source of the work is not available for anyone 499 | to copy, free of charge and under the terms of this License, through a 500 | publicly available network server or other readily accessible means, 501 | then you must either (1) cause the Corresponding Source to be so 502 | available, or (2) arrange to deprive yourself of the benefit of the 503 | patent license for this particular work, or (3) arrange, in a manner 504 | consistent with the requirements of this License, to extend the patent 505 | license to downstream recipients. "Knowingly relying" means you have 506 | actual knowledge that, but for the patent license, your conveying the 507 | covered work in a country, or your recipient's use of the covered work 508 | in a country, would infringe one or more identifiable patents in that 509 | country that you have reason to believe are valid. 510 | 511 | If, pursuant to or in connection with a single transaction or 512 | arrangement, you convey, or propagate by procuring conveyance of, a 513 | covered work, and grant a patent license to some of the parties 514 | receiving the covered work authorizing them to use, propagate, modify 515 | or convey a specific copy of the covered work, then the patent license 516 | you grant is automatically extended to all recipients of the covered 517 | work and works based on it. 518 | 519 | A patent license is "discriminatory" if it does not include within 520 | the scope of its coverage, prohibits the exercise of, or is 521 | conditioned on the non-exercise of one or more of the rights that are 522 | specifically granted under this License. You may not convey a covered 523 | work if you are a party to an arrangement with a third party that is 524 | in the business of distributing software, under which you make payment 525 | to the third party based on the extent of your activity of conveying 526 | the work, and under which the third party grants, to any of the 527 | parties who would receive the covered work from you, a discriminatory 528 | patent license (a) in connection with copies of the covered work 529 | conveyed by you (or copies made from those copies), or (b) primarily 530 | for and in connection with specific products or compilations that 531 | contain the covered work, unless you entered into that arrangement, 532 | or that patent license was granted, prior to 28 March 2007. 533 | 534 | Nothing in this License shall be construed as excluding or limiting 535 | any implied license or other defenses to infringement that may 536 | otherwise be available to you under applicable patent law. 537 | 538 | 12. No Surrender of Others' Freedom. 539 | 540 | If conditions are imposed on you (whether by court order, agreement or 541 | otherwise) that contradict the conditions of this License, they do not 542 | excuse you from the conditions of this License. If you cannot convey a 543 | covered work so as to satisfy simultaneously your obligations under this 544 | License and any other pertinent obligations, then as a consequence you may 545 | not convey it at all. For example, if you agree to terms that obligate you 546 | to collect a royalty for further conveying from those to whom you convey 547 | the Program, the only way you could satisfy both those terms and this 548 | License would be to refrain entirely from conveying the Program. 549 | 550 | 13. Use with the GNU Affero General Public License. 551 | 552 | Notwithstanding any other provision of this License, you have 553 | permission to link or combine any covered work with a work licensed 554 | under version 3 of the GNU Affero General Public License into a single 555 | combined work, and to convey the resulting work. The terms of this 556 | License will continue to apply to the part which is the covered work, 557 | but the special requirements of the GNU Affero General Public License, 558 | section 13, concerning interaction through a network will apply to the 559 | combination as such. 560 | 561 | 14. Revised Versions of this License. 562 | 563 | The Free Software Foundation may publish revised and/or new versions of 564 | the GNU General Public License from time to time. Such new versions will 565 | be similar in spirit to the present version, but may differ in detail to 566 | address new problems or concerns. 567 | 568 | Each version is given a distinguishing version number. If the 569 | Program specifies that a certain numbered version of the GNU General 570 | Public License "or any later version" applies to it, you have the 571 | option of following the terms and conditions either of that numbered 572 | version or of any later version published by the Free Software 573 | Foundation. If the Program does not specify a version number of the 574 | GNU General Public License, you may choose any version ever published 575 | by the Free Software Foundation. 576 | 577 | If the Program specifies that a proxy can decide which future 578 | versions of the GNU General Public License can be used, that proxy's 579 | public statement of acceptance of a version permanently authorizes you 580 | to choose that version for the Program. 581 | 582 | Later license versions may give you additional or different 583 | permissions. However, no additional obligations are imposed on any 584 | author or copyright holder as a result of your choosing to follow a 585 | later version. 586 | 587 | 15. Disclaimer of Warranty. 588 | 589 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 590 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 591 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 592 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 593 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 594 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 595 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 596 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 597 | 598 | 16. Limitation of Liability. 599 | 600 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 601 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 602 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 603 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 604 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 605 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 606 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 607 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 608 | SUCH DAMAGES. 609 | 610 | 17. Interpretation of Sections 15 and 16. 611 | 612 | If the disclaimer of warranty and limitation of liability provided 613 | above cannot be given local legal effect according to their terms, 614 | reviewing courts shall apply local law that most closely approximates 615 | an absolute waiver of all civil liability in connection with the 616 | Program, unless a warranty or assumption of liability accompanies a 617 | copy of the Program in return for a fee. 618 | 619 | END OF TERMS AND CONDITIONS 620 | 621 | How to Apply These Terms to Your New Programs 622 | 623 | If you develop a new program, and you want it to be of the greatest 624 | possible use to the public, the best way to achieve this is to make it 625 | free software which everyone can redistribute and change under these terms. 626 | 627 | To do so, attach the following notices to the program. It is safest 628 | to attach them to the start of each source file to most effectively 629 | state the exclusion of warranty; and each file should have at least 630 | the "copyright" line and a pointer to where the full notice is found. 631 | 632 | 633 | Copyright (C) 634 | 635 | This program is free software: you can redistribute it and/or modify 636 | it under the terms of the GNU General Public License as published by 637 | the Free Software Foundation, either version 3 of the License, or 638 | (at your option) any later version. 639 | 640 | This program is distributed in the hope that it will be useful, 641 | but WITHOUT ANY WARRANTY; without even the implied warranty of 642 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 643 | GNU General Public License for more details. 644 | 645 | You should have received a copy of the GNU General Public License 646 | along with this program. If not, see . 647 | 648 | Also add information on how to contact you by electronic and paper mail. 649 | 650 | If the program does terminal interaction, make it output a short 651 | notice like this when it starts in an interactive mode: 652 | 653 | Copyright (C) 654 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 655 | This is free software, and you are welcome to redistribute it 656 | under certain conditions; type `show c' for details. 657 | 658 | The hypothetical commands `show w' and `show c' should show the appropriate 659 | parts of the General Public License. Of course, your program's commands 660 | might be different; for a GUI interface, you would use an "about box". 661 | 662 | You should also get your employer (if you work as a programmer) or school, 663 | if any, to sign a "copyright disclaimer" for the program, if necessary. 664 | For more information on this, and how to apply and follow the GNU GPL, see 665 | . 666 | 667 | The GNU General Public License does not permit incorporating your program 668 | into proprietary programs. If your program is a subroutine library, you 669 | may consider it more useful to permit linking proprietary applications with 670 | the library. If this is what you want to do, use the GNU Lesser General 671 | Public License instead of this License.
