This program is distributed in the hope that it will be useful, 14 | but WITHOUT ANY WARRANTY; without even the implied warranty of 15 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 16 | GNU General Public License for more details. 17 | 18 | You should have received a copy of the GNU General Public License 19 | along with this program. If not, see . 20 | 21 | 22 | 23 | ******************************************************************************* 24 | 25 | 26 | GNU GENERAL PUBLIC LICENSE 27 | Version 3, 29 June 2007 28 | 29 | Copyright (C) 2007 Free Software Foundation, Inc. 30 | Everyone is permitted to copy and distribute verbatim copies 31 | of this license document, but changing it is not allowed. 32 | 33 | Preamble 34 | 35 | The GNU General Public License is a free, copyleft license for 36 | software and other kinds of works. 37 | 38 | The licenses for most software and other practical works are designed 39 | to take away your freedom to share and change the works. By contrast, 40 | the GNU General Public License is intended to guarantee your freedom to 41 | share and change all versions of a program--to make sure it remains free 42 | software for all its users. We, the Free Software Foundation, use the 43 | GNU General Public License for most of our software; it applies also to 44 | any other work released this way by its authors. You can apply it to 45 | your programs, too. 46 | 47 | When we speak of free software, we are referring to freedom, not 48 | price. Our General Public Licenses are designed to make sure that you 49 | have the freedom to distribute copies of free software (and charge for 50 | them if you wish), that you receive source code or can get it if you 51 | want it, that you can change the software or use pieces of it in new 52 | free programs, and that you know you can do these things. 53 | 54 | To protect your rights, we need to prevent others from denying you 55 | these rights or asking you to surrender the rights. Therefore, you have 56 | certain responsibilities if you distribute copies of the software, or if 57 | you modify it: responsibilities to respect the freedom of others. 58 | 59 | For example, if you distribute copies of such a program, whether 60 | gratis or for a fee, you must pass on to the recipients the same 61 | freedoms that you received. You must make sure that they, too, receive 62 | or can get the source code. And you must show them these terms so they 63 | know their rights. 64 | 65 | Developers that use the GNU GPL protect your rights with two steps: 66 | (1) assert copyright on the software, and (2) offer you this License 67 | giving you legal permission to copy, distribute and/or modify it. 68 | 69 | For the developers' and authors' protection, the GPL clearly explains 70 | that there is no warranty for this free software. For both users' and 71 | authors' sake, the GPL requires that modified versions be marked as 72 | changed, so that their problems will not be attributed erroneously to 73 | authors of previous versions. 74 | 75 | Some devices are designed to deny users access to install or run 76 | modified versions of the software inside them, although the manufacturer 77 | can do so. This is fundamentally incompatible with the aim of 78 | protecting users' freedom to change the software. The systematic 79 | pattern of such abuse occurs in the area of products for individuals to 80 | use, which is precisely where it is most unacceptable. Therefore, we 81 | have designed this version of the GPL to prohibit the practice for those 82 | products. If such problems arise substantially in other domains, we 83 | stand ready to extend this provision to those domains in future versions 84 | of the GPL, as needed to protect the freedom of users. 85 | 86 | Finally, every program is threatened constantly by software patents. 87 | States should not allow patents to restrict development and use of 88 | software on general-purpose computers, but in those that do, we wish to 89 | avoid the special danger that patents applied to a free program could 90 | make it effectively proprietary. To prevent this, the GPL assures that 91 | patents cannot be used to render the program non-free. 92 | 93 | The precise terms and conditions for copying, distribution and 94 | modification follow. 95 | 96 | TERMS AND CONDITIONS 97 | 98 | 0. Definitions. 99 | 100 | "This License" refers to version 3 of the GNU General Public License. 101 | 102 | "Copyright" also means copyright-like laws that apply to other kinds of 103 | works, such as semiconductor masks. 104 | 105 | "The Program" refers to any copyrightable work licensed under this 106 | License. Each licensee is addressed as "you". "Licensees" and 107 | "recipients" may be individuals or organizations. 108 | 109 | To "modify" a work means to copy from or adapt all or part of the work 110 | in a fashion requiring copyright permission, other than the making of an 111 | exact copy. The resulting work is called a "modified version" of the 112 | earlier work or a work "based on" the earlier work. 113 | 114 | A "covered work" means either the unmodified Program or a work based 115 | on the Program. 116 | 117 | To "propagate" a work means to do anything with it that, without 118 | permission, would make you directly or secondarily liable for 119 | infringement under applicable copyright law, except executing it on a 120 | computer or modifying a private copy. Propagation includes copying, 121 | distribution (with or without modification), making available to the 122 | public, and in some countries other activities as well. 123 | 124 | To "convey" a work means any kind of propagation that enables other 125 | parties to make or receive copies. Mere interaction with a user through 126 | a computer network, with no transfer of a copy, is not conveying. 127 | 128 | An interactive user interface displays "Appropriate Legal Notices" 129 | to the extent that it includes a convenient and prominently visible 130 | feature that (1) displays an appropriate copyright notice, and (2) 131 | tells the user that there is no warranty for the work (except to the 132 | extent that warranties are provided), that licensees may convey the 133 | work under this License, and how to view a copy of this License. If 134 | the interface presents a list of user commands or options, such as a 135 | menu, a prominent item in the list meets this criterion. 136 | 137 | 1. Source Code. 138 | 139 | The "source code" for a work means the preferred form of the work 140 | for making modifications to it. "Object code" means any non-source 141 | form of a work. 142 | 143 | A "Standard Interface" means an interface that either is an official 144 | standard defined by a recognized standards body, or, in the case of 145 | interfaces specified for a particular programming language, one that 146 | is widely used among developers working in that language. 147 | 148 | The "System Libraries" of an executable work include anything, other 149 | than the work as a whole, that (a) is included in the normal form of 150 | packaging a Major Component, but which is not part of that Major 151 | Component, and (b) serves only to enable use of the work with that 152 | Major Component, or to implement a Standard Interface for which an 153 | implementation is available to the public in source code form. A 154 | "Major Component", in this context, means a major essential component 155 | (kernel, window system, and so on) of the specific operating system 156 | (if any) on which the executable work runs, or a compiler used to 157 | produce the work, or an object code interpreter used to run it. 158 | 159 | The "Corresponding Source" for a work in object code form means all 160 | the source code needed to generate, install, and (for an executable 161 | work) run the object code and to modify the work, including scripts to 162 | control those activities. However, it does not include the work's 163 | System Libraries, or general-purpose tools or generally available free 164 | programs which are used unmodified in performing those activities but 165 | which are not part of the work. For example, Corresponding Source 166 | includes interface definition files associated with source files for 167 | the work, and the source code for shared libraries and dynamically 168 | linked subprograms that the work is specifically designed to require, 169 | such as by intimate data communication or control flow between those 170 | subprograms and other parts of the work. 171 | 172 | The Corresponding Source need not include anything that users 173 | can regenerate automatically from other parts of the Corresponding 174 | Source. 175 | 176 | The Corresponding Source for a work in source code form is that 177 | same work. 178 | 179 | 2. Basic Permissions. 180 | 181 | All rights granted under this License are granted for the term of 182 | copyright on the Program, and are irrevocable provided the stated 183 | conditions are met. This License explicitly affirms your unlimited 184 | permission to run the unmodified Program. The output from running a 185 | covered work is covered by this License only if the output, given its 186 | content, constitutes a covered work. This License acknowledges your 187 | rights of fair use or other equivalent, as provided by copyright law. 188 | 189 | You may make, run and propagate covered works that you do not 190 | convey, without conditions so long as your license otherwise remains 191 | in force. You may convey covered works to others for the sole purpose 192 | of having them make modifications exclusively for you, or provide you 193 | with facilities for running those works, provided that you comply with 194 | the terms of this License in conveying all material for which you do 195 | not control copyright. Those thus making or running the covered works 196 | for you must do so exclusively on your behalf, under your direction 197 | and control, on terms that prohibit them from making any copies of 198 | your copyrighted material outside their relationship with you. 199 | 200 | Conveying under any other circumstances is permitted solely under 201 | the conditions stated below. Sublicensing is not allowed; section 10 202 | makes it unnecessary. 203 | 204 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 205 | 206 | No covered work shall be deemed part of an effective technological 207 | measure under any applicable law fulfilling obligations under article 208 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 209 | similar laws prohibiting or restricting circumvention of such 210 | measures. 211 | 212 | When you convey a covered work, you waive any legal power to forbid 213 | circumvention of technological measures to the extent such circumvention 214 | is effected by exercising rights under this License with respect to 215 | the covered work, and you disclaim any intention to limit operation or 216 | modification of the work as a means of enforcing, against the work's 217 | users, your or third parties' legal rights to forbid circumvention of 218 | technological measures. 219 | 220 | 4. Conveying Verbatim Copies. 221 | 222 | You may convey verbatim copies of the Program's source code as you 223 | receive it, in any medium, provided that you conspicuously and 224 | appropriately publish on each copy an appropriate copyright notice; 225 | keep intact all notices stating that this License and any 226 | non-permissive terms added in accord with section 7 apply to the code; 227 | keep intact all notices of the absence of any warranty; and give all 228 | recipients a copy of this License along with the Program. 229 | 230 | You may charge any price or no price for each copy that you convey, 231 | and you may offer support or warranty protection for a fee. 232 | 233 | 5. Conveying Modified Source Versions. 234 | 235 | You may convey a work based on the Program, or the modifications to 236 | produce it from the Program, in the form of source code under the 237 | terms of section 4, provided that you also meet all of these conditions: 238 | 239 | a) The work must carry prominent notices stating that you modified 240 | it, and giving a relevant date. 241 | 242 | b) The work must carry prominent notices stating that it is 243 | released under this License and any conditions added under section 244 | 7. This requirement modifies the requirement in section 4 to 245 | "keep intact all notices". 246 | 247 | c) You must license the entire work, as a whole, under this 248 | License to anyone who comes into possession of a copy. This 249 | License will therefore apply, along with any applicable section 7 250 | additional terms, to the whole of the work, and all its parts, 251 | regardless of how they are packaged. This License gives no 252 | permission to license the work in any other way, but it does not 253 | invalidate such permission if you have separately received it. 254 | 255 | d) If the work has interactive user interfaces, each must display 256 | Appropriate Legal Notices; however, if the Program has interactive 257 | interfaces that do not display Appropriate Legal Notices, your 258 | work need not make them do so. 259 | 260 | A compilation of a covered work with other separate and independent 261 | works, which are not by their nature extensions of the covered work, 262 | and which are not combined with it such as to form a larger program, 263 | in or on a volume of a storage or distribution medium, is called an 264 | "aggregate" if the compilation and its resulting copyright are not 265 | used to limit the access or legal rights of the compilation's users 266 | beyond what the individual works permit. Inclusion of a covered work 267 | in an aggregate does not cause this License to apply to the other 268 | parts of the aggregate. 269 | 270 | 6. Conveying Non-Source Forms. 271 | 272 | You may convey a covered work in object code form under the terms 273 | of sections 4 and 5, provided that you also convey the 274 | machine-readable Corresponding Source under the terms of this License, 275 | in one of these ways: 276 | 277 | a) Convey the object code in, or embodied in, a physical product 278 | (including a physical distribution medium), accompanied by the 279 | Corresponding Source fixed on a durable physical medium 280 | customarily used for software interchange. 281 | 282 | b) Convey the object code in, or embodied in, a physical product 283 | (including a physical distribution medium), accompanied by a 284 | written offer, valid for at least three years and valid for as 285 | long as you offer spare parts or customer support for that product 286 | model, to give anyone who possesses the object code either (1) a 287 | copy of the Corresponding Source for all the software in the 288 | product that is covered by this License, on a durable physical 289 | medium customarily used for software interchange, for a price no 290 | more than your reasonable cost of physically performing this 291 | conveying of source, or (2) access to copy the 292 | Corresponding Source from a network server at no charge. 293 | 294 | c) Convey individual copies of the object code with a copy of the 295 | written offer to provide the Corresponding Source. This 296 | alternative is allowed only occasionally and noncommercially, and 297 | only if you received the object code with such an offer, in accord 298 | with subsection 6b. 299 | 300 | d) Convey the object code by offering access from a designated 301 | place (gratis or for a charge), and offer equivalent access to the 302 | Corresponding Source in the same way through the same place at no 303 | further charge. You need not require recipients to copy the 304 | Corresponding Source along with the object code. If the place to 305 | copy the object code is a network server, the Corresponding Source 306 | may be on a different server (operated by you or a third party) 307 | that supports equivalent copying facilities, provided you maintain 308 | clear directions next to the object code saying where to find the 309 | Corresponding Source. Regardless of what server hosts the 310 | Corresponding Source, you remain obligated to ensure that it is 311 | available for as long as needed to satisfy these requirements. 312 | 313 | e) Convey the object code using peer-to-peer transmission, provided 314 | you inform other peers where the object code and Corresponding 315 | Source of the work are being offered to the general public at no 316 | charge under subsection 6d. 317 | 318 | A separable portion of the object code, whose source code is excluded 319 | from the Corresponding Source as a System Library, need not be 320 | included in conveying the object code work. 321 | 322 | A "User Product" is either (1) a "consumer product", which means any 323 | tangible personal property which is normally used for personal, family, 324 | or household purposes, or (2) anything designed or sold for incorporation 325 | into a dwelling. In determining whether a product is a consumer product, 326 | doubtful cases shall be resolved in favor of coverage. For a particular 327 | product received by a particular user, "normally used" refers to a 328 | typical or common use of that class of product, regardless of the status 329 | of the particular user or of the way in which the particular user 330 | actually uses, or expects or is expected to use, the product. A product 331 | is a consumer product regardless of whether the product has substantial 332 | commercial, industrial or non-consumer uses, unless such uses represent 333 | the only significant mode of use of the product. 334 | 335 | "Installation Information" for a User Product means any methods, 336 | procedures, authorization keys, or other information required to install 337 | and execute modified versions of a covered work in that User Product from 338 | a modified version of its Corresponding Source. The information must 339 | suffice to ensure that the continued functioning of the modified object 340 | code is in no case prevented or interfered with solely because 341 | modification has been made. 342 | 343 | If you convey an object code work under this section in, or with, or 344 | specifically for use in, a User Product, and the conveying occurs as 345 | part of a transaction in which the right of possession and use of the 346 | User Product is transferred to the recipient in perpetuity or for a 347 | fixed term (regardless of how the transaction is characterized), the 348 | Corresponding Source conveyed under this section must be accompanied 349 | by the Installation Information. But this requirement does not apply 350 | if neither you nor any third party retains the ability to install 351 | modified object code on the User Product (for example, the work has 352 | been installed in ROM). 353 | 354 | The requirement to provide Installation Information does not include a 355 | requirement to continue to provide support service, warranty, or updates 356 | for a work that has been modified or installed by the recipient, or for 357 | the User Product in which it has been modified or installed. Access to a 358 | network may be denied when the modification itself materially and 359 | adversely affects the operation of the network or violates the rules and 360 | protocols for communication across the network. 361 | 362 | Corresponding Source conveyed, and Installation Information provided, 363 | in accord with this section must be in a format that is publicly 364 | documented (and with an implementation available to the public in 365 | source code form), and must require no special password or key for 366 | unpacking, reading or copying. 367 | 368 | 7. Additional Terms. 369 | 370 | "Additional permissions" are terms that supplement the terms of this 371 | License by making exceptions from one or more of its conditions. 372 | Additional permissions that are applicable to the entire Program shall 373 | be treated as though they were included in this License, to the extent 374 | that they are valid under applicable law. If additional permissions 375 | apply only to part of the Program, that part may be used separately 376 | under those permissions, but the entire Program remains governed by 377 | this License without regard to the additional permissions. 378 | 379 | When you convey a copy of a covered work, you may at your option 380 | remove any additional permissions from that copy, or from any part of 381 | it. (Additional permissions may be written to require their own 382 | removal in certain cases when you modify the work.) You may place 383 | additional permissions on material, added by you to a covered work, 384 | for which you have or can give appropriate copyright permission. 385 | 386 | Notwithstanding any other provision of this License, for material you 387 | add to a covered work, you may (if authorized by the copyright holders of 388 | that material) supplement the terms of this License with terms: 389 | 390 | a) Disclaiming warranty or limiting liability differently from the 391 | terms of sections 15 and 16 of this License; or 392 | 393 | b) Requiring preservation of specified reasonable legal notices or 394 | author attributions in that material or in the Appropriate Legal 395 | Notices displayed by works containing it; or 396 | 397 | c) Prohibiting misrepresentation of the origin of that material, or 398 | requiring that modified versions of such material be marked in 399 | reasonable ways as different from the original version; or 400 | 401 | d) Limiting the use for publicity purposes of names of licensors or 402 | authors of the material; or 403 | 404 | e) Declining to grant rights under trademark law for use of some 405 | trade names, trademarks, or service marks; or 406 | 407 | f) Requiring indemnification of licensors and authors of that 408 | material by anyone who conveys the material (or modified versions of 409 | it) with contractual assumptions of liability to the recipient, for 410 | any liability that these contractual assumptions directly impose on 411 | those licensors and authors. 412 | 413 | All other non-permissive additional terms are considered "further 414 | restrictions" within the meaning of section 10. If the Program as you 415 | received it, or any part of it, contains a notice stating that it is 416 | governed by this License along with a term that is a further 417 | restriction, you may remove that term. If a license document contains 418 | a further restriction but permits relicensing or conveying under this 419 | License, you may add to a covered work material governed by the terms 420 | of that license document, provided that the further restriction does 421 | not survive such relicensing or conveying. 422 | 423 | If you add terms to a covered work in accord with this section, you 424 | must place, in the relevant source files, a statement of the 425 | additional terms that apply to those files, or a notice indicating 426 | where to find the applicable terms. 427 | 428 | Additional terms, permissive or non-permissive, may be stated in the 429 | form of a separately written license, or stated as exceptions; 430 | the above requirements apply either way. 431 | 432 | 8. Termination. 433 | 434 | You may not propagate or modify a covered work except as expressly 435 | provided under this License. Any attempt otherwise to propagate or 436 | modify it is void, and will automatically terminate your rights under 437 | this License (including any patent licenses granted under the third 438 | paragraph of section 11). 439 | 440 | However, if you cease all violation of this License, then your 441 | license from a particular copyright holder is reinstated (a) 442 | provisionally, unless and until the copyright holder explicitly and 443 | finally terminates your license, and (b) permanently, if the copyright 444 | holder fails to notify you of the violation by some reasonable means 445 | prior to 60 days after the cessation. 446 | 447 | Moreover, your license from a particular copyright holder is 448 | reinstated permanently if the copyright holder notifies you of the 449 | violation by some reasonable means, this is the first time you have 450 | received notice of violation of this License (for any work) from that 451 | copyright holder, and you cure the violation prior to 30 days after 452 | your receipt of the notice. 453 | 454 | Termination of your rights under this section does not terminate the 455 | licenses of parties who have received copies or rights from you under 456 | this License. If your rights have been terminated and not permanently 457 | reinstated, you do not qualify to receive new licenses for the same 458 | material under section 10. 459 | 460 | 9. Acceptance Not Required for Having Copies. 461 | 462 | You are not required to accept this License in order to receive or 463 | run a copy of the Program. Ancillary propagation of a covered work 464 | occurring solely as a consequence of using peer-to-peer transmission 465 | to receive a copy likewise does not require acceptance. However, 466 | nothing other than this License grants you permission to propagate or 467 | modify any covered work. These actions infringe copyright if you do 468 | not accept this License. Therefore, by modifying or propagating a 469 | covered work, you indicate your acceptance of this License to do so. 470 | 471 | 10. Automatic Licensing of Downstream Recipients. 472 | 473 | Each time you convey a covered work, the recipient automatically 474 | receives a license from the original licensors, to run, modify and 475 | propagate that work, subject to this License. You are not responsible 476 | for enforcing compliance by third parties with this License. 477 | 478 | An "entity transaction" is a transaction transferring control of an 479 | organization, or substantially all assets of one, or subdividing an 480 | organization, or merging organizations. If propagation of a covered 481 | work results from an entity transaction, each party to that 482 | transaction who receives a copy of the work also receives whatever 483 | licenses to the work the party's predecessor in interest had or could 484 | give under the previous paragraph, plus a right to possession of the 485 | Corresponding Source of the work from the predecessor in interest, if 486 | the predecessor has it or can get it with reasonable efforts. 487 | 488 | You may not impose any further restrictions on the exercise of the 489 | rights granted or affirmed under this License. For example, you may 490 | not impose a license fee, royalty, or other charge for exercise of 491 | rights granted under this License, and you may not initiate litigation 492 | (including a cross-claim or counterclaim in a lawsuit) alleging that 493 | any patent claim is infringed by making, using, selling, offering for 494 | sale, or importing the Program or any portion of it. 495 | 496 | 11. Patents. 497 | 498 | A "contributor" is a copyright holder who authorizes use under this 499 | License of the Program or a work on which the Program is based. The 500 | work thus licensed is called the contributor's "contributor version". 501 | 502 | A contributor's "essential patent claims" are all patent claims 503 | owned or controlled by the contributor, whether already acquired or 504 | hereafter acquired, that would be infringed by some manner, permitted 505 | by this License, of making, using, or selling its contributor version, 506 | but do not include claims that would be infringed only as a 507 | consequence of further modification of the contributor version. For 508 | purposes of this definition, "control" includes the right to grant 509 | patent sublicenses in a manner consistent with the requirements of 510 | this License. 511 | 512 | Each contributor grants you a non-exclusive, worldwide, royalty-free 513 | patent license under the contributor's essential patent claims, to 514 | make, use, sell, offer for sale, import and otherwise run, modify and 515 | propagate the contents of its contributor version. 516 | 517 | In the following three paragraphs, a "patent license" is any express 518 | agreement or commitment, however denominated, not to enforce a patent 519 | (such as an express permission to practice a patent or covenant not to 520 | sue for patent infringement). To "grant" such a patent license to a 521 | party means to make such an agreement or commitment not to enforce a 522 | patent against the party. 523 | 524 | If you convey a covered work, knowingly relying on a patent license, 525 | and the Corresponding Source of the work is not available for anyone 526 | to copy, free of charge and under the terms of this License, through a 527 | publicly available network server or other readily accessible means, 528 | then you must either (1) cause the Corresponding Source to be so 529 | available, or (2) arrange to deprive yourself of the benefit of the 530 | patent license for this particular work, or (3) arrange, in a manner 531 | consistent with the requirements of this License, to extend the patent 532 | license to downstream recipients. "Knowingly relying" means you have 533 | actual knowledge that, but for the patent license, your conveying the 534 | covered work in a country, or your recipient's use of the covered work 535 | in a country, would infringe one or more identifiable patents in that 536 | country that you have reason to believe are valid. 537 | 538 | If, pursuant to or in connection with a single transaction or 539 | arrangement, you convey, or propagate by procuring conveyance of, a 540 | covered work, and grant a patent license to some of the parties 541 | receiving the covered work authorizing them to use, propagate, modify 542 | or convey a specific copy of the covered work, then the patent license 543 | you grant is automatically extended to all recipients of the covered 544 | work and works based on it. 545 | 546 | A patent license is "discriminatory" if it does not include within 547 | the scope of its coverage, prohibits the exercise of, or is 548 | conditioned on the non-exercise of one or more of the rights that are 549 | specifically granted under this License. You may not convey a covered 550 | work if you are a party to an arrangement with a third party that is 551 | in the business of distributing software, under which you make payment 552 | to the third party based on the extent of your activity of conveying 553 | the work, and under which the third party grants, to any of the 554 | parties who would receive the covered work from you, a discriminatory 555 | patent license (a) in connection with copies of the covered work 556 | conveyed by you (or copies made from those copies), or (b) primarily 557 | for and in connection with specific products or compilations that 558 | contain the covered work, unless you entered into that arrangement, 559 | or that patent license was granted, prior to 28 March 2007. 560 | 561 | Nothing in this License shall be construed as excluding or limiting 562 | any implied license or other defenses to infringement that may 563 | otherwise be available to you under applicable patent law. 564 | 565 | 12. No Surrender of Others' Freedom. 566 | 567 | If conditions are imposed on you (whether by court order, agreement or 568 | otherwise) that contradict the conditions of this License, they do not 569 | excuse you from the conditions of this License. If you cannot convey a 570 | covered work so as to satisfy simultaneously your obligations under this 571 | License and any other pertinent obligations, then as a consequence you may 572 | not convey it at all. For example, if you agree to terms that obligate you 573 | to collect a royalty for further conveying from those to whom you convey 574 | the Program, the only way you could satisfy both those terms and this 575 | License would be to refrain entirely from conveying the Program. 576 | 577 | 13. Use with the GNU Affero General Public License. 578 | 579 | Notwithstanding any other provision of this License, you have 580 | permission to link or combine any covered work with a work licensed 581 | under version 3 of the GNU Affero General Public License into a single 582 | combined work, and to convey the resulting work. The terms of this 583 | License will continue to apply to the part which is the covered work, 584 | but the special requirements of the GNU Affero General Public License, 585 | section 13, concerning interaction through a network will apply to the 586 | combination as such. 587 | 588 | 14. Revised Versions of this License. 589 | 590 | The Free Software Foundation may publish revised and/or new versions of 591 | the GNU General Public License from time to time. Such new versions will 592 | be similar in spirit to the present version, but may differ in detail to 593 | address new problems or concerns. 594 | 595 | Each version is given a distinguishing version number. If the 596 | Program specifies that a certain numbered version of the GNU General 597 | Public License "or any later version" applies to it, you have the 598 | option of following the terms and conditions either of that numbered 599 | version or of any later version published by the Free Software 600 | Foundation. If the Program does not specify a version number of the 601 | GNU General Public License, you may choose any version ever published 602 | by the Free Software Foundation. 603 | 604 | If the Program specifies that a proxy can decide which future 605 | versions of the GNU General Public License can be used, that proxy's 606 | public statement of acceptance of a version permanently authorizes you 607 | to choose that version for the Program. 608 | 609 | Later license versions may give you additional or different 610 | permissions. However, no additional obligations are imposed on any 611 | author or copyright holder as a result of your choosing to follow a 612 | later version. 613 | 614 | 15. Disclaimer of Warranty. 615 | 616 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 617 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 618 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 619 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 620 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 621 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 622 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 623 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 624 | 625 | 16. Limitation of Liability. 626 | 627 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 628 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 629 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 630 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 631 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 632 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 633 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 634 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 635 | SUCH DAMAGES. 636 | 637 | 17. Interpretation of Sections 15 and 16. 638 | 639 | If the disclaimer of warranty and limitation of liability provided 640 | above cannot be given local legal effect according to their terms, 641 | reviewing courts shall apply local law that most closely approximates 642 | an absolute waiver of all civil liability in connection with the 643 | Program, unless a warranty or assumption of liability accompanies a 644 | copy of the Program in return for a fee. 645 | 646 | END OF TERMS AND CONDITIONS 647 | --------------------------------------------------------------------------------
