By contrast, the 65 <acronym class="acronym">GNU</acronym> General Public License is intended to guarantee your 66 freedom to share and change all versions of a program—to make sure it 67 remains free software for all its users. We, the Free Software Foundation, 68 use the <acronym class="acronym">GNU</acronym> General Public License for most of our 69 software; it applies also to any other work released this way by its 70 authors. You can apply it to your programs, too. 71 </p><p> 72 When we speak of free software, we are referring to freedom, not price. Our 73 General Public Licenses are designed to make sure that you have the freedom 74 to distribute copies of free software (and charge for them if you wish), 75 that you receive source code or can get it if you want it, that you can 76 change the software or use pieces of it in new free programs, and that you 77 know you can do these things. 78 </p><p> 79 To protect your rights, we need to prevent others from denying you these 80 rights or asking you to surrender the rights. Therefore, you have certain 81 responsibilities if you distribute copies of the software, or if you modify 82 it: responsibilities to respect the freedom of others. 83 </p><p> 84 For example, if you distribute copies of such a program, whether gratis or 85 for a fee, you must pass on to the recipients the same freedoms that you 86 received. You must make sure that they, too, receive or can get the source 87 code. And you must show them these terms so they know their rights. 88 </p><p> 89 Developers that use the <acronym class="acronym">GNU</acronym> <acronym class="acronym">GPL</acronym> 90 protect your rights with two steps: (1) assert copyright on the software, 91 and (2) offer you this License giving you legal permission to copy, 92 distribute and/or modify it. 93 </p><p> 94 For the developers’ and authors’ protection, the 95 <acronym class="acronym">GPL</acronym> clearly explains that there is no warranty for this 96 free software. For both users’ and authors’ sake, the 97 <acronym class="acronym">GPL</acronym> requires that modified versions be marked as changed, 98 so that their problems will not be attributed erroneously to authors of 99 previous versions. 100 </p><p> 101 Some devices are designed to deny users access to install or run modified 102 versions of the software inside them, although the manufacturer can do so. 103 This is fundamentally incompatible with the aim of protecting users’ 104 freedom to change the software. The systematic pattern of such abuse occurs 105 in the area of products for individuals to use, which is precisely where it 106 is most unacceptable. Therefore, we have designed this version of the 107 <acronym class="acronym">GPL</acronym> to prohibit the practice for those products. If such 108 problems arise substantially in other domains, we stand ready to extend this 109 provision to those domains in future versions of the <acronym class="acronym">GPL</acronym>, 110 as needed to protect the freedom of users. 111 </p><p> 112 Finally, every program is threatened constantly by software patents. States 113 should not allow patents to restrict development and use of software on 114 general-purpose computers, but in those that do, we wish to avoid the 115 special danger that patents applied to a free program could make it 116 effectively proprietary. To prevent this, the <acronym class="acronym">GPL</acronym> 117 assures that patents cannot be used to render the program non-free. 118 </p><p> 119 The precise terms and conditions for copying, distribution and modification 120 follow. 121 </p><h2><a name="id2693435"></a> 122 TERMS AND CONDITIONS 123 </h2><h2><a name="id2693439"></a> 124 0. Definitions. 125 </h2><p> 126 “This License” refers to version 3 of the <acronym class="acronym">GNU</acronym> 127 General Public License. 128 </p><p> 129 “Copyright” also means copyright-like laws that apply to other 130 kinds of works, such as semiconductor masks. 131 </p><p> 132 “The Program” refers to any copyrightable work licensed under 133 this License. Each licensee is addressed as “you”. 134 “Licensees” and “recipients” may be individuals or 135 organizations. 136 </p><p> 137 To “modify” a work means to copy from or adapt all or part of 138 the work in a fashion requiring copyright permission, other than the making 139 of an exact copy. The resulting work is called a “modified 140 version” of the earlier work or a work “based on” the 141 earlier work. 142 </p><p> 143 A “covered work” means either the unmodified Program or a work 144 based on the Program. 145 </p><p> 146 To “propagate” a work means to do anything with it that, without 147 permission, would make you directly or secondarily liable for infringement 148 under applicable copyright law, except executing it on a computer or 149 modifying a private copy. Propagation includes copying, distribution (with 150 or without modification), making available to the public, and in some 151 countries other activities as well. 152 </p><p> 153 To “convey” a work means any kind of propagation that enables 154 other parties to make or receive copies. Mere interaction with a user 155 through a computer network, with no transfer of a copy, is not conveying. 156 </p><p> 157 An interactive user interface displays “Appropriate Legal 158 Notices” to the extent that it includes a convenient and prominently 159 visible feature that (1) displays an appropriate copyright notice, and (2) 160 tells the user that there is no warranty for the work (except to the extent 161 that warranties are provided), that licensees may convey the work under this 162 License, and how to view a copy of this License. If the interface presents 163 a list of user commands or options, such as a menu, a prominent item in the 164 list meets this criterion. 165 </p><h2><a name="id2693532"></a> 166 1. Source Code. 167 </h2><p> 168 The “source code” for a work means the preferred form of the 169 work for making modifications to it. “Object code” means any 170 non-source form of a work. 171 </p><p> 172 A “Standard Interface” means an interface that either is an 173 official standard defined by a recognized standards body, or, in the case of 174 interfaces specified for a particular programming language, one that is 175 widely used among developers working in that language. 176 </p><p> 177 The “System Libraries” of an executable work include anything, 178 other than the work as a whole, that (a) is included in the normal form of 179 packaging a Major Component, but which is not part of that Major Component, 180 and (b) serves only to enable use of the work with that Major Component, or 181 to implement a Standard Interface for which an implementation is available 182 to the public in source code form. A “Major Component”, in this 183 context, means a major essential component (kernel, window system, and so 184 on) of the specific operating system (if any) on which the executable work 185 runs, or a compiler used to produce the work, or an object code interpreter 186 used to run it. 187 </p><p> 188 The “Corresponding Source” for a work in object code form means 189 all the source code needed to generate, install, and (for an executable 190 work) run the object code and to modify the work, including scripts to 191 control those activities. However, it does not include the work’s 192 System Libraries, or general-purpose tools or generally available free 193 programs which are used unmodified in performing those activities but which 194 are not part of the work. For example, Corresponding Source includes 195 interface definition files associated with source files for the work, and 196 the source code for shared libraries and dynamically linked subprograms that 197 the work is specifically designed to require, such as by intimate data 198 communication or control flow between those subprograms and other parts of 199 the work. 200 </p><p> 201 The Corresponding Source need not include anything that users can regenerate 202 automatically from other parts of the Corresponding Source. 203 </p><p> 204 The Corresponding Source for a work in source code form is that same work. 205 </p><h2><a name="id2693630"></a> 206 2. Basic Permissions. 207 </h2><p> 208 All rights granted under this License are granted for the term of copyright 209 on the Program, and are irrevocable provided the stated conditions are met. 210 This License explicitly affirms your unlimited permission to run the 211 unmodified Program. The output from running a covered work is covered by 212 this License only if the output, given its content, constitutes a covered 213 work. This License acknowledges your rights of fair use or other 214 equivalent, as provided by copyright law. 215 </p><p> 216 You may make, run and propagate covered works that you do not convey, 217 without conditions so long as your license otherwise remains in force. You 218 may convey covered works to others for the sole purpose of having them make 219 modifications exclusively for you, or provide you with facilities for 220 running those works, provided that you comply with the terms of this License 221 in conveying all material for which you do not control copyright. Those 222 thus making or running the covered works for you must do so exclusively on 223 your behalf, under your direction and control, on terms that prohibit them 224 from making any copies of your copyrighted material outside their 225 relationship with you. 226 </p><p> 227 Conveying under any other circumstances is permitted solely under the 228 conditions stated below. Sublicensing is not allowed; section 10 makes it 229 unnecessary. 230 </p><h2><a name="id2693681"></a> 231 3. Protecting Users’ Legal Rights From Anti-Circumvention Law. 232 </h2><p> 233 No covered work shall be deemed part of an effective technological measure 234 under any applicable law fulfilling obligations under article 11 of the WIPO 235 copyright treaty adopted on 20 December 1996, or similar laws prohibiting or 236 restricting circumvention of such measures. 237 </p><p> 238 When you convey a covered work, you waive any legal power to forbid 239 circumvention of technological measures to the extent such circumvention is 240 effected by exercising rights under this License with respect to the covered 241 work, and you disclaim any intention to limit operation or modification of 242 the work as a means of enforcing, against the work’s users, your or 243 third parties’ legal rights to forbid circumvention of technological 244 measures. 245 </p><h2><a name="id2693716"></a> 246 4. Conveying Verbatim Copies. 247 </h2><p> 248 You may convey verbatim copies of the Program’s source code as you 249 receive it, in any medium, provided that you conspicuously and appropriately 250 publish on each copy an appropriate copyright notice; keep intact all 251 notices stating that this License and any non-permissive terms added in 252 accord with section 7 apply to the code; keep intact all notices of the 253 absence of any warranty; and give all recipients a copy of this License 254 along with the Program. 255 </p><p> 256 You may charge any price or no price for each copy that you convey, and you 257 may offer support or warranty protection for a fee. 258 </p><h2><a name="id2693743"></a> 259 5. Conveying Modified Source Versions. 260 </h2><p> 261 You may convey a work based on the Program, or the modifications to produce 262 it from the Program, in the form of source code under the terms of section 263 4, provided that you also meet all of these conditions: 264 </p><div class="orderedlist"><ol type="a"><li><p> 265 The work must carry prominent notices stating that you modified it, and 266 giving a relevant date. 267 </p></li><li><p> 268 The work must carry prominent notices stating that it is released under 269 this License and any conditions added under section 7. This requirement 270 modifies the requirement in section 4 to “keep intact all 271 notices”. 272 </p></li><li><p> 273 You must license the entire work, as a whole, under this License to 274 anyone who comes into possession of a copy. This License will therefore 275 apply, along with any applicable section 7 additional terms, to the 276 whole of the work, and all its parts, regardless of how they are 277 packaged. This License gives no permission to license the work in any 278 other way, but it does not invalidate such permission if you have 279 separately received it. 280 </p></li><li><p> 281 If the work has interactive user interfaces, each must display 282 Appropriate Legal Notices; however, if the Program has interactive 283 interfaces that do not display Appropriate Legal Notices, your work need 284 not make them do so. 285 </p></li></ol></div><p> 286 A compilation of a covered work with other separate and independent works, 287 which are not by their nature extensions of the covered work, and which are 288 not combined with it such as to form a larger program, in or on a volume of 289 a storage or distribution medium, is called an “aggregate” if 290 the compilation and its resulting copyright are not used to limit the access 291 or legal rights of the compilation’s users beyond what the individual works 292 permit. Inclusion of a covered work in an aggregate does not cause 293 this License to apply to the other parts of the aggregate. 294 </p><h2><a name="id2693839"></a> 295 6. Conveying Non-Source Forms. 296 </h2><p> 297 You may convey a covered work in object code form under the terms of 298 sections 4 and 5, provided that you also convey the machine-readable 299 Corresponding Source under the terms of this License, in one of these ways: 300 </p><div class="orderedlist"><ol type="a"><li><p> 301 Convey the object code in, or embodied in, a physical product (including 302 a physical distribution medium), accompanied by the Corresponding Source 303 fixed on a durable physical medium customarily used for software 304 interchange. 305 </p></li><li><p> 306 Convey the object code in, or embodied in, a physical product (including 307 a physical distribution medium), accompanied by a written offer, valid 308 for at least three years and valid for as long as you offer spare parts 309 or customer support for that product model, to give anyone who possesses 310 the object code either (1) a copy of the Corresponding Source for all 311 the software in the product that is covered by this License, on a 312 durable physical medium customarily used for software interchange, for a 313 price no more than your reasonable cost of physically performing this 314 conveying of source, or (2) access to copy the Corresponding Source from 315 a network server at no charge. 316 </p></li><li><p> 317 Convey individual copies of the object code with a copy of the written 318 offer to provide the Corresponding Source. This alternative is allowed 319 only occasionally and noncommercially, and only if you received the 320 object code with such an offer, in accord with subsection 6b. 321 </p></li><li><p> 322 Convey the object code by offering access from a designated place 323 (gratis or for a charge), and offer equivalent access to the 324 Corresponding Source in the same way through the same place at no 325 further charge. You need not require recipients to copy the 326 Corresponding Source along with the object code. If the place to copy 327 the object code is a network server, the Corresponding Source may be on 328 a different server (operated by you or a third party) that supports 329 equivalent copying facilities, provided you maintain clear directions 330 next to the object code saying where to find the Corresponding Source. 331 Regardless of what server hosts the Corresponding Source, you remain 332 obligated to ensure that it is available for as long as needed to 333 satisfy these requirements. 334 </p></li><li><p> 335 Convey the object code using peer-to-peer transmission, provided you 336 inform other peers where the object code and Corresponding Source of the 337 work are being offered to the general public at no charge under 338 subsection 6d. 339 </p></li></ol></div><p> 340 A separable portion of the object code, whose source code is excluded from 341 the Corresponding Source as a System Library, need not be included in 342 conveying the object code work. 343 </p><p> 344 A “User Product” is either (1) a “consumer product”, 345 which means any tangible personal property which is normally used for 346 personal, family, or household purposes, or (2) anything designed or sold 347 for incorporation into a dwelling. In determining whether a product is a 348 consumer product, doubtful cases shall be resolved in favor of coverage. 349 For a particular product received by a particular user, “normally 350 used” refers to a typical or common use of that class of product, 351 regardless of the status of the particular user or of the way in which the 352 particular user actually uses, or expects or is expected to use, the 353 product. A product is a consumer product regardless of whether the product 354 has substantial commercial, industrial or non-consumer uses, unless such 355 uses represent the only significant mode of use of the product. 356 </p><p> 357 “Installation Information” for a User Product means any methods, 358 procedures, authorization keys, or other information required to install and 359 execute modified versions of a covered work in that User Product from a 360 modified version of its Corresponding Source. The information must suffice 361 to ensure that the continued functioning of the modified object code is in 362 no case prevented or interfered with solely because modification has been 363 made. 364 </p><p> 365 If you convey an object code work under this section in, or with, or 366 specifically for use in, a User Product, and the conveying occurs as part of 367 a transaction in which the right of possession and use of the User Product 368 is transferred to the recipient in perpetuity or for a fixed term 369 (regardless of how the transaction is characterized), the Corresponding 370 Source conveyed under this section must be accompanied by the Installation 371 Information. But this requirement does not apply if neither you nor any 372 third party retains the ability to install modified object code on the User 373 Product (for example, the work has been installed in 374 <acronym class="acronym">ROM</acronym>). 375 </p><p> 376 The requirement to provide Installation Information does not include a 377 requirement to continue to provide support service, warranty, or updates for 378 a work that has been modified or installed by the recipient, or for the User 379 Product in which it has been modified or installed. Access to a network may 380 be denied when the modification itself materially and adversely affects the 381 operation of the network or violates the rules and protocols for 382 communication across the network. 383 </p><p> 384 Corresponding Source conveyed, and Installation Information provided, in 385 accord with this section must be in a format that is publicly documented 386 (and with an implementation available to the public in source code form), 387 and must require no special password or key for unpacking, reading or 388 copying. 389 </p><h2><a name="id2694028"></a> 390 7. Additional Terms. 391 </h2><p> 392 “Additional permissions” are terms that supplement the terms of 393 this License by making exceptions from one or more of its conditions. 394 Additional permissions that are applicable to the entire Program shall be 395 treated as though they were included in this License, to the extent that 396 they are valid under applicable law. If additional permissions apply only 397 to part of the Program, that part may be used separately under those 398 permissions, but the entire Program remains governed by this License 399 without regard to the additional permissions. 400 </p><p> 401 When you convey a copy of a covered work, you may at your option remove any 402 additional permissions from that copy, or from any part of it. (Additional 403 permissions may be written to require their own removal in certain cases 404 when you modify the work.) You may place additional permissions on 405 material, added by you to a covered work, for which you have or can give 406 appropriate copyright permission. 407 </p><p> 408 Notwithstanding any other provision of this License, for material you add 409 to a covered work, you may (if authorized by the copyright holders of that 410 material) supplement the terms of this License with terms: 411 </p><div class="orderedlist"><ol type="a"><li><p> 412 Disclaiming warranty or limiting liability differently from the terms 413 of sections 15 and 16 of this License; or 414 </p></li><li><p> 415 Requiring preservation of specified reasonable legal notices or author 416 attributions in that material or in the Appropriate Legal Notices 417 displayed by works containing it; or 418 </p></li><li><p> 419 Prohibiting misrepresentation of the origin of that material, or 420 requiring that modified versions of such material be marked in 421 reasonable ways as different from the original version; or 422 </p></li><li><p> 423 Limiting the use for publicity purposes of names of licensors or 424 authors of the material; or 425 </p></li><li><p> 426 Declining to grant rights under trademark law for use of some trade 427 names, trademarks, or service marks; or 428 </p></li><li><p> 429 Requiring indemnification of licensors and authors of that material by 430 anyone who conveys the material (or modified versions of it) with 431 contractual assumptions of liability to the recipient, for any 432 liability that these contractual assumptions directly impose on those 433 licensors and authors. 434 </p></li></ol></div><p> 435 All other non-permissive additional terms are considered “further 436 restrictions” within the meaning of section 10. If the Program as 437 you received it, or any part of it, contains a notice stating that it is 438 governed by this License along with a term that is a further restriction, 439 you may remove that term. If a license document contains a further 440 restriction but permits relicensing or conveying under this License, you 441 may add to a covered work material governed by the terms of that license 442 document, provided that the further restriction does not survive such 443 relicensing or conveying. 444 </p><p> 445 If you add terms to a covered work in accord with this section, you must 446 place, in the relevant source files, a statement of the additional terms 447 that apply to those files, or a notice indicating where to find the 448 applicable terms. 449 </p><p> 450 Additional terms, permissive or non-permissive, may be stated in the form 451 of a separately written license, or stated as exceptions; the above 452 requirements apply either way. 453 </p><h2><a name="id2694164"></a> 454 8. Termination. 455 </h2><p> 456 You may not propagate or modify a covered work except as expressly provided 457 under this License. Any attempt otherwise to propagate or modify it is 458 void, and will automatically terminate your rights under this License 459 (including any patent licenses granted under the third paragraph of section 460 11). 461 </p><p> 462 However, if you cease all violation of this License, then your license from 463 a particular copyright holder is reinstated (a) provisionally, unless and 464 until the copyright holder explicitly and finally terminates your license, 465 and (b) permanently, if the copyright holder fails to notify you of the 466 violation by some reasonable means prior to 60 days after the cessation. 467 </p><p> 468 Moreover, your license from a particular copyright holder is reinstated 469 permanently if the copyright holder notifies you of the violation by some 470 reasonable means, this is the first time you have received notice of 471 violation of this License (for any work) from that copyright holder, and 472 you cure the violation prior to 30 days after your receipt of the notice. 473 </p><p> 474 Termination of your rights under this section does not terminate the 475 licenses of parties who have received copies or rights from you under this 476 License. If your rights have been terminated and not permanently 477 reinstated, you do not qualify to receive new licenses for the same 478 material under section 10. 479 </p><h2><a name="id2694208"></a> 480 9. Acceptance Not Required for Having Copies. 481 </h2><p> 482 You are not required to accept this License in order to receive or run a 483 copy of the Program. Ancillary propagation of a covered work occurring 484 solely as a consequence of using peer-to-peer transmission to receive a 485 copy likewise does not require acceptance. However, nothing other than 486 this License grants you permission to propagate or modify any covered work. 487 These actions infringe copyright if you do not accept this License. 488 Therefore, by modifying or propagating a covered work, you indicate your 489 acceptance of this License to do so. 490 </p><h2><a name="id2694227"></a> 491 10. Automatic Licensing of Downstream Recipients. 492 </h2><p> 493 Each time you convey a covered work, the recipient automatically receives a 494 license from the original licensors, to run, modify and propagate that 495 work, subject to this License. You are not responsible for enforcing 496 compliance by third parties with this License. 497 </p><p> 498 An “entity transaction” is a transaction transferring control 499 of an organization, or substantially all assets of one, or subdividing an 500 organization, or merging organizations. If propagation of a covered work 501 results from an entity transaction, each party to that transaction who 502 receives a copy of the work also receives whatever licenses to the work the 503 party’s predecessor in interest had or could give under the previous 504 paragraph, plus a right to possession of the Corresponding Source of the 505 work from the predecessor in interest, if the predecessor has it or can get 506 it with reasonable efforts. 507 </p><p> 508 You may not impose any further restrictions on the exercise of the rights 509 granted or affirmed under this License. For example, you may not impose a 510 license fee, royalty, or other charge for exercise of rights granted under 511 this License, and you may not initiate litigation (including a cross-claim 512 or counterclaim in a lawsuit) alleging that any patent claim is infringed 513 by making, using, selling, offering for sale, or importing the Program or 514 any portion of it. 515 </p><h2><a name="id2694279"></a> 516 11. Patents. 517 </h2><p> 518 A “contributor” is a copyright holder who authorizes use under 519 this License of the Program or a work on which the Program is based. The 520 work thus licensed is called the contributor’s “contributor 521 version”. 522 </p><p> 523 A contributor’s “essential patent claims” are all patent 524 claims owned or controlled by the contributor, whether already acquired or 525 hereafter acquired, that would be infringed by some manner, permitted by 526 this License, of making, using, or selling its contributor version, but do 527 not include claims that would be infringed only as a consequence of further 528 modification of the contributor version. For purposes of this definition, 529 “control” includes the right to grant patent sublicenses in a 530 manner consistent with the requirements of this License. 531 </p><p> 532 Each contributor grants you a non-exclusive, worldwide, royalty-free patent 533 license under the contributor’s essential patent claims, to make, use, 534 sell, offer for sale, import and otherwise run, modify and propagate the 535 contents of its contributor version. 536 </p><p> 537 In the following three paragraphs, a “patent license” is any 538 express agreement or commitment, however denominated, not to enforce a 539 patent (such as an express permission to practice a patent or covenant not 540 to sue for patent infringement). To “grant” such a patent 541 license to a party means to make such an agreement or commitment not to 542 enforce a patent against the party. 543 </p><p> 544 If you convey a covered work, knowingly relying on a patent license, and the 545 Corresponding Source of the work is not available for anyone to copy, free 546 of charge and under the terms of this License, through a publicly available 547 network server or other readily accessible means, then you must either (1) 548 cause the Corresponding Source to be so available, or (2) arrange to deprive 549 yourself of the benefit of the patent license for this particular work, or 550 (3) arrange, in a manner consistent with the requirements of this License, 551 to extend the patent license to downstream recipients. “Knowingly 552 relying” means you have actual knowledge that, but for the patent 553 license, your conveying the covered work in a country, or your 554 recipient’s use of the covered work in a country, would infringe one 555 or more identifiable patents in that country that you have reason to believe 556 are valid. 557 </p><p> 558 If, pursuant to or in connection with a single transaction or arrangement, 559 you convey, or propagate by procuring conveyance of, a covered work, and 560 grant a patent license to some of the parties receiving the covered work 561 authorizing them to use, propagate, modify or convey a specific copy of the 562 covered work, then the patent license you grant is automatically extended to 563 all recipients of the covered work and works based on it. 564 </p><p> 565 A patent license is “discriminatory” if it does not include 566 within the scope of its coverage, prohibits the exercise of, or is 567 conditioned on the non-exercise of one or more of the rights that are 568 specifically granted under this License. You may not convey a covered work 569 if you are a party to an arrangement with a third party that is in the 570 business of distributing software, under which you make payment to the third 571 party based on the extent of your activity of conveying the work, and under 572 which the third party grants, to any of the parties who would receive the 573 covered work from you, a discriminatory patent license (a) in connection 574 with copies of the covered work conveyed by you (or copies made from those 575 copies), or (b) primarily for and in connection with specific products or 576 compilations that contain the covered work, unless you entered into that 577 arrangement, or that patent license was granted, prior to 28 March 2007. 578 </p><p> 579 Nothing in this License shall be construed as excluding or limiting any 580 implied license or other defenses to infringement that may otherwise be 581 available to you under applicable patent law. 582 </p><h2><a name="id2694425"></a> 583 12. No Surrender of Others’ Freedom. 584 </h2><p> 585 If conditions are imposed on you (whether by court order, agreement or 586 otherwise) that contradict the conditions of this License, they do not 587 excuse you from the conditions of this License. If you cannot convey a 588 covered work so as to satisfy simultaneously your obligations under this 589 License and any other pertinent obligations, then as a consequence you may 590 not convey it at all. For example, if you agree to terms that obligate you 591 to collect a royalty for further conveying from those to whom you convey the 592 Program, the only way you could satisfy both those terms and this License 593 would be to refrain entirely from conveying the Program. 594 </p><h2><a name="id2694447"></a> 595 13. Use with the <acronym class="acronym">GNU</acronym> Affero General Public License. 596 </h2><p> 597 Notwithstanding any other provision of this License, you have permission to 598 link or combine any covered work with a work licensed under version 3 of the 599 <acronym class="acronym">GNU</acronym> Affero General Public License into a single combined 600 work, and to convey the resulting work. The terms of this License will 601 continue to apply to the part which is the covered work, but the special 602 requirements of the <acronym class="acronym">GNU</acronym> Affero General Public License, 603 section 13, concerning interaction through a network will apply to the 604 combination as such. 605 </p><h2><a name="id2694476"></a> 606 14. Revised Versions of this License. 607 </h2><p> 608 The Free Software Foundation may publish revised and/or new versions of the 609 <acronym class="acronym">GNU</acronym> General Public License from time to time. Such new 610 versions will be similar in spirit to the present version, but may differ in 611 detail to address new problems or concerns. 612 </p><p> 613 Each version is given a distinguishing version number. If the Program 614 specifies that a certain numbered version of the <acronym class="acronym">GNU</acronym> 615 General Public License “or any later version” applies to it, you 616 have the option of following the terms and conditions either of that 617 numbered version or of any later version published by the Free Software 618 Foundation. If the Program does not specify a version number of the 619 <acronym class="acronym">GNU</acronym> General Public License, you may choose any version 620 ever published by the Free Software Foundation. 621 </p><p> 622 If the Program specifies that a proxy can decide which future versions of 623 the <acronym class="acronym">GNU</acronym> General Public License can be used, that 624 proxy’s public statement of acceptance of a version permanently 625 authorizes you to choose that version for the Program. 626 </p><p> 627 Later license versions may give you additional or different permissions. 628 However, no additional obligations are imposed on any author or copyright 629 holder as a result of your choosing to follow a later version. 630 </p><h2><a name="id2694538"></a> 631 15. Disclaimer of Warranty. 632 </h2><p> 633 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE 634 LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR 635 OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF 636 ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE 637 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. 638 THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH 639 YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL 640 NECESSARY SERVICING, REPAIR OR CORRECTION. 641 </p><h2><a name="id2694564"></a> 642 16. Limitation of Liability. 643 </h2><p> 644 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL 645 ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE 646 PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 647 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE 648 OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA 649 OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 650 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 651 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 652 SUCH DAMAGES. 653 </p><h2><a name="id2694584"></a> 654 17. Interpretation of Sections 15 and 16. 655 </h2><p> 656 If the disclaimer of warranty and limitation of liability provided above 657 cannot be given local legal effect according to their terms, reviewing 658 courts shall apply local law that most closely approximates an absolute 659 waiver of all civil liability in connection with the Program, unless a 660 warranty or assumption of liability accompanies a copy of the Program in 661 return for a fee. 662 </p><h2><a name="id2694601"></a> 663 END OF TERMS AND CONDITIONS 664 </h2><h2><a name="id2694605"></a> 665 How to Apply These Terms to Your New Programs 666 </h2><p> 667 If you develop a new program, and you want it to be of the greatest possible 668 use to the public, the best way to achieve this is to make it free software 669 which everyone can redistribute and change under these terms. 670 </p><p> 671 To do so, attach the following notices to the program. It is safest to 672 attach them to the start of each source file to most effectively state the 673 exclusion of warranty; and each file should have at least the 674 “copyright” line and a pointer to where the full notice is 675 found. 676 </p><pre class="screen"> 677<em class="replaceable"><code>one line to give the program’s name and a brief idea of what it does.</code></em> 678Copyright (C) <em class="replaceable"><code>year</code></em> <em class="replaceable"><code>name of author</code></em> 679 680This program is free software: you can redistribute it and/or modify 681it under the terms of the <acronym class="acronym">GNU</acronym> General Public License as published by 682the Free Software Foundation, either version 3 of the License, or 683(at your option) any later version. 684 685This program is distributed in the hope that it will be useful, 686but WITHOUT ANY WARRANTY; without even the implied warranty of 687MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
