By contrast, 30 | the GNU General Public License is intended to guarantee your freedom to 31 | share and change all versions of a program--to make sure it remains free 32 | software for all its users. We, the Free Software Foundation, use the 33 | GNU General Public License for most of our software; it applies also to 34 | any other work released this way by its authors. You can apply it to 35 | your programs, too. 36 | 37 | When we speak of free software, we are referring to freedom, not 38 | price. Our General Public Licenses are designed to make sure that you 39 | have the freedom to distribute copies of free software (and charge for 40 | them if you wish), that you receive source code or can get it if you 41 | want it, that you can change the software or use pieces of it in new 42 | free programs, and that you know you can do these things. 43 | 44 | To protect your rights, we need to prevent others from denying you 45 | these rights or asking you to surrender the rights. Therefore, you have 46 | certain responsibilities if you distribute copies of the software, or if 47 | you modify it: responsibilities to respect the freedom of others. 48 | 49 | For example, if you distribute copies of such a program, whether 50 | gratis or for a fee, you must pass on to the recipients the same 51 | freedoms that you received. You must make sure that they, too, receive 52 | or can get the source code. And you must show them these terms so they 53 | know their rights. 54 | 55 | Developers that use the GNU GPL protect your rights with two steps: 56 | (1) assert copyright on the software, and (2) offer you this License 57 | giving you legal permission to copy, distribute and/or modify it. 58 | 59 | For the developers' and authors' protection, the GPL clearly explains 60 | that there is no warranty for this free software. For both users' and 61 | authors' sake, the GPL requires that modified versions be marked as 62 | changed, so that their problems will not be attributed erroneously to 63 | authors of previous versions. 64 | 65 | Some devices are designed to deny users access to install or run 66 | modified versions of the software inside them, although the manufacturer 67 | can do so. This is fundamentally incompatible with the aim of 68 | protecting users' freedom to change the software. The systematic 69 | pattern of such abuse occurs in the area of products for individuals to 70 | use, which is precisely where it is most unacceptable. Therefore, we 71 | have designed this version of the GPL to prohibit the practice for those 72 | products. If such problems arise substantially in other domains, we 73 | stand ready to extend this provision to those domains in future versions 74 | of the GPL, as needed to protect the freedom of users. 75 | 76 | Finally, every program is threatened constantly by software patents. 77 | States should not allow patents to restrict development and use of 78 | software on general-purpose computers, but in those that do, we wish to 79 | avoid the special danger that patents applied to a free program could 80 | make it effectively proprietary. To prevent this, the GPL assures that 81 | patents cannot be used to render the program non-free. 82 | 83 | The precise terms and conditions for copying, distribution and 84 | modification follow. 85 | 86 | TERMS AND CONDITIONS 87 | 88 | 0. Definitions. 89 | 90 | "This License" refers to version 3 of the GNU General Public License. 91 | 92 | "Copyright" also means copyright-like laws that apply to other kinds of 93 | works, such as semiconductor masks. 94 | 95 | "The Program" refers to any copyrightable work licensed under this 96 | License. Each licensee is addressed as "you". "Licensees" and 97 | "recipients" may be individuals or organizations. 98 | 99 | To "modify" a work means to copy from or adapt all or part of the work 100 | in a fashion requiring copyright permission, other than the making of an 101 | exact copy. The resulting work is called a "modified version" of the 102 | earlier work or a work "based on" the earlier work. 103 | 104 | A "covered work" means either the unmodified Program or a work based 105 | on the Program. 106 | 107 | To "propagate" a work means to do anything with it that, without 108 | permission, would make you directly or secondarily liable for 109 | infringement under applicable copyright law, except executing it on a 110 | computer or modifying a private copy. Propagation includes copying, 111 | distribution (with or without modification), making available to the 112 | public, and in some countries other activities as well. 113 | 114 | To "convey" a work means any kind of propagation that enables other 115 | parties to make or receive copies. Mere interaction with a user through 116 | a computer network, with no transfer of a copy, is not conveying. 117 | 118 | An interactive user interface displays "Appropriate Legal Notices" 119 | to the extent that it includes a convenient and prominently visible 120 | feature that (1) displays an appropriate copyright notice, and (2) 121 | tells the user that there is no warranty for the work (except to the 122 | extent that warranties are provided), that licensees may convey the 123 | work under this License, and how to view a copy of this License. If 124 | the interface presents a list of user commands or options, such as a 125 | menu, a prominent item in the list meets this criterion. 126 | 127 | 1. Source Code. 128 | 129 | The "source code" for a work means the preferred form of the work 130 | for making modifications to it. "Object code" means any non-source 131 | form of a work. 132 | 133 | A "Standard Interface" means an interface that either is an official 134 | standard defined by a recognized standards body, or, in the case of 135 | interfaces specified for a particular programming language, one that 136 | is widely used among developers working in that language. 137 | 138 | The "System Libraries" of an executable work include anything, other 139 | than the work as a whole, that (a) is included in the normal form of 140 | packaging a Major Component, but which is not part of that Major 141 | Component, and (b) serves only to enable use of the work with that 142 | Major Component, or to implement a Standard Interface for which an 143 | implementation is available to the public in source code form. A 144 | "Major Component", in this context, means a major essential component 145 | (kernel, window system, and so on) of the specific operating system 146 | (if any) on which the executable work runs, or a compiler used to 147 | produce the work, or an object code interpreter used to run it. 148 | 149 | The "Corresponding Source" for a work in object code form means all 150 | the source code needed to generate, install, and (for an executable 151 | work) run the object code and to modify the work, including scripts to 152 | control those activities. However, it does not include the work's 153 | System Libraries, or general-purpose tools or generally available free 154 | programs which are used unmodified in performing those activities but 155 | which are not part of the work. For example, Corresponding Source 156 | includes interface definition files associated with source files for 157 | the work, and the source code for shared libraries and dynamically 158 | linked subprograms that the work is specifically designed to require, 159 | such as by intimate data communication or control flow between those 160 | subprograms and other parts of the work. 161 | 162 | The Corresponding Source need not include anything that users 163 | can regenerate automatically from other parts of the Corresponding 164 | Source. 165 | 166 | The Corresponding Source for a work in source code form is that 167 | same work. 168 | 169 | 2. Basic Permissions. 170 | 171 | All rights granted under this License are granted for the term of 172 | copyright on the Program, and are irrevocable provided the stated 173 | conditions are met. This License explicitly affirms your unlimited 174 | permission to run the unmodified Program. The output from running a 175 | covered work is covered by this License only if the output, given its 176 | content, constitutes a covered work. This License acknowledges your 177 | rights of fair use or other equivalent, as provided by copyright law. 178 | 179 | You may make, run and propagate covered works that you do not 180 | convey, without conditions so long as your license otherwise remains 181 | in force. You may convey covered works to others for the sole purpose 182 | of having them make modifications exclusively for you, or provide you 183 | with facilities for running those works, provided that you comply with 184 | the terms of this License in conveying all material for which you do 185 | not control copyright. Those thus making or running the covered works 186 | for you must do so exclusively on your behalf, under your direction 187 | and control, on terms that prohibit them from making any copies of 188 | your copyrighted material outside their relationship with you. 189 | 190 | Conveying under any other circumstances is permitted solely under 191 | the conditions stated below. Sublicensing is not allowed; section 10 192 | makes it unnecessary. 193 | 194 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 195 | 196 | No covered work shall be deemed part of an effective technological 197 | measure under any applicable law fulfilling obligations under article 198 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 199 | similar laws prohibiting or restricting circumvention of such 200 | measures. 201 | 202 | When you convey a covered work, you waive any legal power to forbid 203 | circumvention of technological measures to the extent such circumvention 204 | is effected by exercising rights under this License with respect to 205 | the covered work, and you disclaim any intention to limit operation or 206 | modification of the work as a means of enforcing, against the work's 207 | users, your or third parties' legal rights to forbid circumvention of 208 | technological measures. 209 | 210 | 4. Conveying Verbatim Copies. 211 | 212 | You may convey verbatim copies of the Program's source code as you 213 | receive it, in any medium, provided that you conspicuously and 214 | appropriately publish on each copy an appropriate copyright notice; 215 | keep intact all notices stating that this License and any 216 | non-permissive terms added in accord with section 7 apply to the code; 217 | keep intact all notices of the absence of any warranty; and give all 218 | recipients a copy of this License along with the Program. 219 | 220 | You may charge any price or no price for each copy that you convey, 221 | and you may offer support or warranty protection for a fee. 222 | 223 | 5. Conveying Modified Source Versions. 224 | 225 | You may convey a work based on the Program, or the modifications to 226 | produce it from the Program, in the form of source code under the 227 | terms of section 4, provided that you also meet all of these conditions: 228 | 229 | a) The work must carry prominent notices stating that you modified 230 | it, and giving a relevant date. 231 | 232 | b) The work must carry prominent notices stating that it is 233 | released under this License and any conditions added under section 234 | 7. This requirement modifies the requirement in section 4 to 235 | "keep intact all notices". 236 | 237 | c) You must license the entire work, as a whole, under this 238 | License to anyone who comes into possession of a copy. This 239 | License will therefore apply, along with any applicable section 7 240 | additional terms, to the whole of the work, and all its parts, 241 | regardless of how they are packaged. This License gives no 242 | permission to license the work in any other way, but it does not 243 | invalidate such permission if you have separately received it. 244 | 245 | d) If the work has interactive user interfaces, each must display 246 | Appropriate Legal Notices; however, if the Program has interactive 247 | interfaces that do not display Appropriate Legal Notices, your 248 | work need not make them do so. 249 | 250 | A compilation of a covered work with other separate and independent 251 | works, which are not by their nature extensions of the covered work, 252 | and which are not combined with it such as to form a larger program, 253 | in or on a volume of a storage or distribution medium, is called an 254 | "aggregate" if the compilation and its resulting copyright are not 255 | used to limit the access or legal rights of the compilation's users 256 | beyond what the individual works permit. Inclusion of a covered work 257 | in an aggregate does not cause this License to apply to the other 258 | parts of the aggregate. 259 | 260 | 6. Conveying Non-Source Forms. 261 | 262 | You may convey a covered work in object code form under the terms 263 | of sections 4 and 5, provided that you also convey the 264 | machine-readable Corresponding Source under the terms of this License, 265 | in one of these ways: 266 | 267 | a) Convey the object code in, or embodied in, a physical product 268 | (including a physical distribution medium), accompanied by the 269 | Corresponding Source fixed on a durable physical medium 270 | customarily used for software interchange. 271 | 272 | b) Convey the object code in, or embodied in, a physical product 273 | (including a physical distribution medium), accompanied by a 274 | written offer, valid for at least three years and valid for as 275 | long as you offer spare parts or customer support for that product 276 | model, to give anyone who possesses the object code either (1) a 277 | copy of the Corresponding Source for all the software in the 278 | product that is covered by this License, on a durable physical 279 | medium customarily used for software interchange, for a price no 280 | more than your reasonable cost of physically performing this 281 | conveying of source, or (2) access to copy the 282 | Corresponding Source from a network server at no charge. 283 | 284 | c) Convey individual copies of the object code with a copy of the 285 | written offer to provide the Corresponding Source. This 286 | alternative is allowed only occasionally and noncommercially, and 287 | only if you received the object code with such an offer, in accord 288 | with subsection 6b. 289 | 290 | d) Convey the object code by offering access from a designated 291 | place (gratis or for a charge), and offer equivalent access to the 292 | Corresponding Source in the same way through the same place at no 293 | further charge. You need not require recipients to copy the 294 | Corresponding Source along with the object code. If the place to 295 | copy the object code is a network server, the Corresponding Source 296 | may be on a different server (operated by you or a third party) 297 | that supports equivalent copying facilities, provided you maintain 298 | clear directions next to the object code saying where to find the 299 | Corresponding Source. Regardless of what server hosts the 300 | Corresponding Source, you remain obligated to ensure that it is 301 | available for as long as needed to satisfy these requirements. 302 | 303 | e) Convey the object code using peer-to-peer transmission, provided 304 | you inform other peers where the object code and Corresponding 305 | Source of the work are being offered to the general public at no 306 | charge under subsection 6d. 307 | 308 | A separable portion of the object code, whose source code is excluded 309 | from the Corresponding Source as a System Library, need not be 310 | included in conveying the object code work. 311 | 312 | A "User Product" is either (1) a "consumer product", which means any 313 | tangible personal property which is normally used for personal, family, 314 | or household purposes, or (2) anything designed or sold for incorporation 315 | into a dwelling. In determining whether a product is a consumer product, 316 | doubtful cases shall be resolved in favor of coverage. For a particular 317 | product received by a particular user, "normally used" refers to a 318 | typical or common use of that class of product, regardless of the status 319 | of the particular user or of the way in which the particular user 320 | actually uses, or expects or is expected to use, the product. A product 321 | is a consumer product regardless of whether the product has substantial 322 | commercial, industrial or non-consumer uses, unless such uses represent 323 | the only significant mode of use of the product. 324 | 325 | "Installation Information" for a User Product means any methods, 326 | procedures, authorization keys, or other information required to install 327 | and execute modified versions of a covered work in that User Product from 328 | a modified version of its Corresponding Source. The information must 329 | suffice to ensure that the continued functioning of the modified object 330 | code is in no case prevented or interfered with solely because 331 | modification has been made. 332 | 333 | If you convey an object code work under this section in, or with, or 334 | specifically for use in, a User Product, and the conveying occurs as 335 | part of a transaction in which the right of possession and use of the 336 | User Product is transferred to the recipient in perpetuity or for a 337 | fixed term (regardless of how the transaction is characterized), the 338 | Corresponding Source conveyed under this section must be accompanied 339 | by the Installation Information. But this requirement does not apply 340 | if neither you nor any third party retains the ability to install 341 | modified object code on the User Product (for example, the work has 342 | been installed in ROM). 343 | 344 | The requirement to provide Installation Information does not include a 345 | requirement to continue to provide support service, warranty, or updates 346 | for a work that has been modified or installed by the recipient, or for 347 | the User Product in which it has been modified or installed. Access to a 348 | network may be denied when the modification itself materially and 349 | adversely affects the operation of the network or violates the rules and 350 | protocols for communication across the network. 351 | 352 | Corresponding Source conveyed, and Installation Information provided, 353 | in accord with this section must be in a format that is publicly 354 | documented (and with an implementation available to the public in 355 | source code form), and must require no special password or key for 356 | unpacking, reading or copying. 357 | 358 | 7. Additional Terms. 359 | 360 | "Additional permissions" are terms that supplement the terms of this 361 | License by making exceptions from one or more of its conditions. 362 | Additional permissions that are applicable to the entire Program shall 363 | be treated as though they were included in this License, to the extent 364 | that they are valid under applicable law. If additional permissions 365 | apply only to part of the Program, that part may be used separately 366 | under those permissions, but the entire Program remains governed by 367 | this License without regard to the additional permissions. 368 | 369 | When you convey a copy of a covered work, you may at your option 370 | remove any additional permissions from that copy, or from any part of 371 | it. (Additional permissions may be written to require their own 372 | removal in certain cases when you modify the work.) You may place 373 | additional permissions on material, added by you to a covered work, 374 | for which you have or can give appropriate copyright permission. 375 | 376 | Notwithstanding any other provision of this License, for material you 377 | add to a covered work, you may (if authorized by the copyright holders of 378 | that material) supplement the terms of this License with terms: 379 | 380 | a) Disclaiming warranty or limiting liability differently from the 381 | terms of sections 15 and 16 of this License; or 382 | 383 | b) Requiring preservation of specified reasonable legal notices or 384 | author attributions in that material or in the Appropriate Legal 385 | Notices displayed by works containing it; or 386 | 387 | c) Prohibiting misrepresentation of the origin of that material, or 388 | requiring that modified versions of such material be marked in 389 | reasonable ways as different from the original version; or 390 | 391 | d) Limiting the use for publicity purposes of names of licensors or 392 | authors of the material; or 393 | 394 | e) Declining to grant rights under trademark law for use of some 395 | trade names, trademarks, or service marks; or 396 | 397 | f) Requiring indemnification of licensors and authors of that 398 | material by anyone who conveys the material (or modified versions of 399 | it) with contractual assumptions of liability to the recipient, for 400 | any liability that these contractual assumptions directly impose on 401 | those licensors and authors. 402 | 403 | All other non-permissive additional terms are considered "further 404 | restrictions" within the meaning of section 10. If the Program as you 405 | received it, or any part of it, contains a notice stating that it is 406 | governed by this License along with a term that is a further 407 | restriction, you may remove that term. If a license document contains 408 | a further restriction but permits relicensing or conveying under this 409 | License, you may add to a covered work material governed by the terms 410 | of that license document, provided that the further restriction does 411 | not survive such relicensing or conveying. 412 | 413 | If you add terms to a covered work in accord with this section, you 414 | must place, in the relevant source files, a statement of the 415 | additional terms that apply to those files, or a notice indicating 416 | where to find the applicable terms. 417 | 418 | Additional terms, permissive or non-permissive, may be stated in the 419 | form of a separately written license, or stated as exceptions; 420 | the above requirements apply either way. 421 | 422 | 8. Termination. 423 | 424 | You may not propagate or modify a covered work except as expressly 425 | provided under this License. Any attempt otherwise to propagate or 426 | modify it is void, and will automatically terminate your rights under 427 | this License (including any patent licenses granted under the third 428 | paragraph of section 11). 429 | 430 | However, if you cease all violation of this License, then your 431 | license from a particular copyright holder is reinstated (a) 432 | provisionally, unless and until the copyright holder explicitly and 433 | finally terminates your license, and (b) permanently, if the copyright 434 | holder fails to notify you of the violation by some reasonable means 435 | prior to 60 days after the cessation. 436 | 437 | Moreover, your license from a particular copyright holder is 438 | reinstated permanently if the copyright holder notifies you of the 439 | violation by some reasonable means, this is the first time you have 440 | received notice of violation of this License (for any work) from that 441 | copyright holder, and you cure the violation prior to 30 days after 442 | your receipt of the notice. 443 | 444 | Termination of your rights under this section does not terminate the 445 | licenses of parties who have received copies or rights from you under 446 | this License. If your rights have been terminated and not permanently 447 | reinstated, you do not qualify to receive new licenses for the same 448 | material under section 10. 449 | 450 | 9. Acceptance Not Required for Having Copies. 451 | 452 | You are not required to accept this License in order to receive or 453 | run a copy of the Program. Ancillary propagation of a covered work 454 | occurring solely as a consequence of using peer-to-peer transmission 455 | to receive a copy likewise does not require acceptance. However, 456 | nothing other than this License grants you permission to propagate or 457 | modify any covered work. These actions infringe copyright if you do 458 | not accept this License. Therefore, by modifying or propagating a 459 | covered work, you indicate your acceptance of this License to do so. 460 | 461 | 10. Automatic Licensing of Downstream Recipients. 462 | 463 | Each time you convey a covered work, the recipient automatically 464 | receives a license from the original licensors, to run, modify and 465 | propagate that work, subject to this License. You are not responsible 466 | for enforcing compliance by third parties with this License. 467 | 468 | An "entity transaction" is a transaction transferring control of an 469 | organization, or substantially all assets of one, or subdividing an 470 | organization, or merging organizations. If propagation of a covered 471 | work results from an entity transaction, each party to that 472 | transaction who receives a copy of the work also receives whatever 473 | licenses to the work the party's predecessor in interest had or could 474 | give under the previous paragraph, plus a right to possession of the 475 | Corresponding Source of the work from the predecessor in interest, if 476 | the predecessor has it or can get it with reasonable efforts. 477 | 478 | You may not impose any further restrictions on the exercise of the 479 | rights granted or affirmed under this License. For example, you may 480 | not impose a license fee, royalty, or other charge for exercise of 481 | rights granted under this License, and you may not initiate litigation 482 | (including a cross-claim or counterclaim in a lawsuit) alleging that 483 | any patent claim is infringed by making, using, selling, offering for 484 | sale, or importing the Program or any portion of it. 485 | 486 | 11. Patents. 487 | 488 | A "contributor" is a copyright holder who authorizes use under this 489 | License of the Program or a work on which the Program is based. The 490 | work thus licensed is called the contributor's "contributor version". 491 | 492 | A contributor's "essential patent claims" are all patent claims 493 | owned or controlled by the contributor, whether already acquired or 494 | hereafter acquired, that would be infringed by some manner, permitted 495 | by this License, of making, using, or selling its contributor version, 496 | but do not include claims that would be infringed only as a 497 | consequence of further modification of the contributor version. For 498 | purposes of this definition, "control" includes the right to grant 499 | patent sublicenses in a manner consistent with the requirements of 500 | this License. 501 | 502 | Each contributor grants you a non-exclusive, worldwide, royalty-free 503 | patent license under the contributor's essential patent claims, to 504 | make, use, sell, offer for sale, import and otherwise run, modify and 505 | propagate the contents of its contributor version. 506 | 507 | In the following three paragraphs, a "patent license" is any express 508 | agreement or commitment, however denominated, not to enforce a patent 509 | (such as an express permission to practice a patent or covenant not to 510 | sue for patent infringement). To "grant" such a patent license to a 511 | party means to make such an agreement or commitment not to enforce a 512 | patent against the party. 513 | 514 | If you convey a covered work, knowingly relying on a patent license, 515 | and the Corresponding Source of the work is not available for anyone 516 | to copy, free of charge and under the terms of this License, through a 517 | publicly available network server or other readily accessible means, 518 | then you must either (1) cause the Corresponding Source to be so 519 | available, or (2) arrange to deprive yourself of the benefit of the 520 | patent license for this particular work, or (3) arrange, in a manner 521 | consistent with the requirements of this License, to extend the patent 522 | license to downstream recipients. "Knowingly relying" means you have 523 | actual knowledge that, but for the patent license, your conveying the 524 | covered work in a country, or your recipient's use of the covered work 525 | in a country, would infringe one or more identifiable patents in that 526 | country that you have reason to believe are valid. 527 | 528 | If, pursuant to or in connection with a single transaction or 529 | arrangement, you convey, or propagate by procuring conveyance of, a 530 | covered work, and grant a patent license to some of the parties 531 | receiving the covered work authorizing them to use, propagate, modify 532 | or convey a specific copy of the covered work, then the patent license 533 | you grant is automatically extended to all recipients of the covered 534 | work and works based on it. 535 | 536 | A patent license is "discriminatory" if it does not include within 537 | the scope of its coverage, prohibits the exercise of, or is 538 | conditioned on the non-exercise of one or more of the rights that are 539 | specifically granted under this License. You may not convey a covered 540 | work if you are a party to an arrangement with a third party that is 541 | in the business of distributing software, under which you make payment 542 | to the third party based on the extent of your activity of conveying 543 | the work, and under which the third party grants, to any of the 544 | parties who would receive the covered work from you, a discriminatory 545 | patent license (a) in connection with copies of the covered work 546 | conveyed by you (or copies made from those copies), or (b) primarily 547 | for and in connection with specific products or compilations that 548 | contain the covered work, unless you entered into that arrangement, 549 | or that patent license was granted, prior to 28 March 2007. 550 | 551 | Nothing in this License shall be construed as excluding or limiting 552 | any implied license or other defenses to infringement that may 553 | otherwise be available to you under applicable patent law. 554 | 555 | 12. No Surrender of Others' Freedom. 556 | 557 | If conditions are imposed on you (whether by court order, agreement or 558 | otherwise) that contradict the conditions of this License, they do not 559 | excuse you from the conditions of this License. If you cannot convey a 560 | covered work so as to satisfy simultaneously your obligations under this 561 | License and any other pertinent obligations, then as a consequence you may 562 | not convey it at all. For example, if you agree to terms that obligate you 563 | to collect a royalty for further conveying from those to whom you convey 564 | the Program, the only way you could satisfy both those terms and this 565 | License would be to refrain entirely from conveying the Program. 566 | 567 | 13. Use with the GNU Affero General Public License. 568 | 569 | Notwithstanding any other provision of this License, you have 570 | permission to link or combine any covered work with a work licensed 571 | under version 3 of the GNU Affero General Public License into a single 572 | combined work, and to convey the resulting work. The terms of this 573 | License will continue to apply to the part which is the covered work, 574 | but the special requirements of the GNU Affero General Public License, 575 | section 13, concerning interaction through a network will apply to the 576 | combination as such. 577 | 578 | 14. Revised Versions of this License. 579 | 580 | The Free Software Foundation may publish revised and/or new versions of 581 | the GNU General Public License from time to time. Such new versions will 582 | be similar in spirit to the present version, but may differ in detail to 583 | address new problems or concerns. 584 | 585 | Each version is given a distinguishing version number. If the 586 | Program specifies that a certain numbered version of the GNU General 587 | Public License "or any later version" applies to it, you have the 588 | option of following the terms and conditions either of that numbered 589 | version or of any later version published by the Free Software 590 | Foundation. If the Program does not specify a version number of the 591 | GNU General Public License, you may choose any version ever published 592 | by the Free Software Foundation. 593 | 594 | If the Program specifies that a proxy can decide which future 595 | versions of the GNU General Public License can be used, that proxy's 596 | public statement of acceptance of a version permanently authorizes you 597 | to choose that version for the Program. 598 | 599 | Later license versions may give you additional or different 600 | permissions. However, no additional obligations are imposed on any 601 | author or copyright holder as a result of your choosing to follow a 602 | later version. 603 | 604 | 15. Disclaimer of Warranty. 605 | 606 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 607 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 608 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 609 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 610 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 611 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 612 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 613 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 614 | 615 | 16. Limitation of Liability. 616 | 617 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 618 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 619 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 620 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 621 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 622 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 623 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 624 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 625 | SUCH DAMAGES. 626 | 627 | 17. Interpretation of Sections 15 and 16. 628 | 629 | If the disclaimer of warranty and limitation of liability provided 630 | above cannot be given local legal effect according to their terms, 631 | reviewing courts shall apply local law that most closely approximates 632 | an absolute waiver of all civil liability in connection with the 633 | Program, unless a warranty or assumption of liability accompanies a 634 | copy of the Program in return for a fee. 635 | 636 | END OF TERMS AND CONDITIONS 637 | 638 | How to Apply These Terms to Your New Programs 639 | 640 | If you develop a new program, and you want it to be of the greatest 641 | possible use to the public, the best way to achieve this is to make it 642 | free software which everyone can redistribute and change under these terms. 643 | 644 | To do so, attach the following notices to the program. It is safest 645 | to attach them to the start of each source file to most effectively 646 | state the exclusion of warranty; and each file should have at least 647 | the "copyright" line and a pointer to where the full notice is found. 648 | 649 | 650 | Copyright (C) 651 | 652 | This program is free software: you can redistribute it and/or modify 653 | it under the terms of the GNU General Public License as published by 654 | the Free Software Foundation, either version 3 of the License, or 655 | (at your option) any later version. 656 | 657 | This program is distributed in the hope that it will be useful, 658 | but WITHOUT ANY WARRANTY; without even the implied warranty of 659 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 660 | GNU General Public License for more details. 661 | 662 | You should have received a copy of the GNU General Public License 663 | along with this program. If not, see . 664 | 665 | Also add information on how to contact you by electronic and paper mail. 666 | 667 | If the program does terminal interaction, make it output a short 668 | notice like this when it starts in an interactive mode: 669 | 670 | Copyright (C) 671 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 672 | This is free software, and you are welcome to redistribute it 673 | under certain conditions; type `show c' for details. 674 | 675 | The hypothetical commands `show w' and `show c' should show the appropriate 676 | parts of the General Public License. Of course, your program's commands 677 | might be different; for a GUI interface, you would use an "about box". 678 | 679 | You should also get your employer (if you work as a programmer) or school, 680 | if any, to sign a "copyright disclaimer" for the program, if necessary. 681 | For more information on this, and how to apply and follow the GNU GPL, see 682 | . 683 | 684 | The GNU General Public License does not permit incorporating your program 685 | into proprietary programs. If your program is a subroutine library, you 686 | may consider it more useful to permit linking proprietary applications with 687 | the library. If this is what you want to do, use the GNU Lesser General 688 | Public License instead of this License. But first, please read 689 | . 690 | --------------------------------------------------------------------------------
