By contrast, 18 the GNU General Public License is intended to guarantee your freedom to 19 share and change all versions of a program--to make sure it remains free 20 software for all its users. We, the Free Software Foundation, use the 21 GNU General Public License for most of our software; it applies also to 22 any other work released this way by its authors. You can apply it to 23 your programs, too. 24 25 When we speak of free software, we are referring to freedom, not 26 price. Our General Public Licenses are designed to make sure that you 27 have the freedom to distribute copies of free software (and charge for 28 them if you wish), that you receive source code or can get it if you 29 want it, that you can change the software or use pieces of it in new 30 free programs, and that you know you can do these things. 31 32 To protect your rights, we need to prevent others from denying you 33 these rights or asking you to surrender the rights. Therefore, you have 34 certain responsibilities if you distribute copies of the software, or if 35 you modify it: responsibilities to respect the freedom of others. 36 37 For example, if you distribute copies of such a program, whether 38 gratis or for a fee, you must pass on to the recipients the same 39 freedoms that you received. You must make sure that they, too, receive 40 or can get the source code. And you must show them these terms so they 41 know their rights. 42 43 Developers that use the GNU GPL protect your rights with two steps: 44 (1) assert copyright on the software, and (2) offer you this License 45 giving you legal permission to copy, distribute and/or modify it. 46 47 For the developers' and authors' protection, the GPL clearly explains 48 that there is no warranty for this free software. For both users' and 49 authors' sake, the GPL requires that modified versions be marked as 50 changed, so that their problems will not be attributed erroneously to 51 authors of previous versions. 52 53 Some devices are designed to deny users access to install or run 54 modified versions of the software inside them, although the manufacturer 55 can do so. This is fundamentally incompatible with the aim of 56 protecting users' freedom to change the software. The systematic 57 pattern of such abuse occurs in the area of products for individuals to 58 use, which is precisely where it is most unacceptable. Therefore, we 59 have designed this version of the GPL to prohibit the practice for those 60 products. If such problems arise substantially in other domains, we 61 stand ready to extend this provision to those domains in future versions 62 of the GPL, as needed to protect the freedom of users. 63 64 Finally, every program is threatened constantly by software patents. 65 States should not allow patents to restrict development and use of 66 software on general-purpose computers, but in those that do, we wish to 67 avoid the special danger that patents applied to a free program could 68 make it effectively proprietary. To prevent this, the GPL assures that 69 patents cannot be used to render the program non-free. 70 71 The precise terms and conditions for copying, distribution and 72 modification follow. 73 74 TERMS AND CONDITIONS 75 76 0. Definitions. 77 78 "This License" refers to version 3 of the GNU General Public License. 79 80 "Copyright" also means copyright-like laws that apply to other kinds of 81 works, such as semiconductor masks. 82 83 "The Program" refers to any copyrightable work licensed under this 84 License. Each licensee is addressed as "you". "Licensees" and 85 "recipients" may be individuals or organizations. 86 87 To "modify" a work means to copy from or adapt all or part of the work 88 in a fashion requiring copyright permission, other than the making of an 89 exact copy. The resulting work is called a "modified version" of the 90 earlier work or a work "based on" the earlier work. 91 92 A "covered work" means either the unmodified Program or a work based 93 on the Program. 94 95 To "propagate" a work means to do anything with it that, without 96 permission, would make you directly or secondarily liable for 97 infringement under applicable copyright law, except executing it on a 98 computer or modifying a private copy. Propagation includes copying, 99 distribution (with or without modification), making available to the 100 public, and in some countries other activities as well. 101 102 To "convey" a work means any kind of propagation that enables other 103 parties to make or receive copies. Mere interaction with a user through 104 a computer network, with no transfer of a copy, is not conveying. 105 106 An interactive user interface displays "Appropriate Legal Notices" 107 to the extent that it includes a convenient and prominently visible 108 feature that (1) displays an appropriate copyright notice, and (2) 109 tells the user that there is no warranty for the work (except to the 110 extent that warranties are provided), that licensees may convey the 111 work under this License, and how to view a copy of this License. If 112 the interface presents a list of user commands or options, such as a 113 menu, a prominent item in the list meets this criterion. 114 115 1. Source Code. 116 117 The "source code" for a work means the preferred form of the work 118 for making modifications to it. "Object code" means any non-source 119 form of a work. 120 121 A "Standard Interface" means an interface that either is an official 122 standard defined by a recognized standards body, or, in the case of 123 interfaces specified for a particular programming language, one that 124 is widely used among developers working in that language. 125 126 The "System Libraries" of an executable work include anything, other 127 than the work as a whole, that (a) is included in the normal form of 128 packaging a Major Component, but which is not part of that Major 129 Component, and (b) serves only to enable use of the work with that 130 Major Component, or to implement a Standard Interface for which an 131 implementation is available to the public in source code form. A 132 "Major Component", in this context, means a major essential component 133 (kernel, window system, and so on) of the specific operating system 134 (if any) on which the executable work runs, or a compiler used to 135 produce the work, or an object code interpreter used to run it. 136 137 The "Corresponding Source" for a work in object code form means all 138 the source code needed to generate, install, and (for an executable 139 work) run the object code and to modify the work, including scripts to 140 control those activities. However, it does not include the work's 141 System Libraries, or general-purpose tools or generally available free 142 programs which are used unmodified in performing those activities but 143 which are not part of the work. For example, Corresponding Source 144 includes interface definition files associated with source files for 145 the work, and the source code for shared libraries and dynamically 146 linked subprograms that the work is specifically designed to require, 147 such as by intimate data communication or control flow between those 148 subprograms and other parts of the work. 149 150 The Corresponding Source need not include anything that users 151 can regenerate automatically from other parts of the Corresponding 152 Source. 153 154 The Corresponding Source for a work in source code form is that 155 same work. 156 157 2. Basic Permissions. 158 159 All rights granted under this License are granted for the term of 160 copyright on the Program, and are irrevocable provided the stated 161 conditions are met. This License explicitly affirms your unlimited 162 permission to run the unmodified Program. The output from running a 163 covered work is covered by this License only if the output, given its 164 content, constitutes a covered work. This License acknowledges your 165 rights of fair use or other equivalent, as provided by copyright law. 166 167 You may make, run and propagate covered works that you do not 168 convey, without conditions so long as your license otherwise remains 169 in force. You may convey covered works to others for the sole purpose 170 of having them make modifications exclusively for you, or provide you 171 with facilities for running those works, provided that you comply with 172 the terms of this License in conveying all material for which you do 173 not control copyright. Those thus making or running the covered works 174 for you must do so exclusively on your behalf, under your direction 175 and control, on terms that prohibit them from making any copies of 176 your copyrighted material outside their relationship with you. 177 178 Conveying under any other circumstances is permitted solely under 179 the conditions stated below. Sublicensing is not allowed; section 10 180 makes it unnecessary. 181 182 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 183 184 No covered work shall be deemed part of an effective technological 185 measure under any applicable law fulfilling obligations under article 186 11 of the WIPO copyright treaty adopted on 20 December 1996, or 187 similar laws prohibiting or restricting circumvention of such 188 measures. 189 190 When you convey a covered work, you waive any legal power to forbid 191 circumvention of technological measures to the extent such circumvention 192 is effected by exercising rights under this License with respect to 193 the covered work, and you disclaim any intention to limit operation or 194 modification of the work as a means of enforcing, against the work's 195 users, your or third parties' legal rights to forbid circumvention of 196 technological measures. 197 198 4. Conveying Verbatim Copies. 199 200 You may convey verbatim copies of the Program's source code as you 201 receive it, in any medium, provided that you conspicuously and 202 appropriately publish on each copy an appropriate copyright notice; 203 keep intact all notices stating that this License and any 204 non-permissive terms added in accord with section 7 apply to the code; 205 keep intact all notices of the absence of any warranty; and give all 206 recipients a copy of this License along with the Program. 207 208 You may charge any price or no price for each copy that you convey, 209 and you may offer support or warranty protection for a fee. 210 211 5. Conveying Modified Source Versions. 212 213 You may convey a work based on the Program, or the modifications to 214 produce it from the Program, in the form of source code under the 215 terms of section 4, provided that you also meet all of these conditions: 216 217 a) The work must carry prominent notices stating that you modified 218 it, and giving a relevant date. 219 220 b) The work must carry prominent notices stating that it is 221 released under this License and any conditions added under section 222 7. This requirement modifies the requirement in section 4 to 223 "keep intact all notices". 224 225 c) You must license the entire work, as a whole, under this 226 License to anyone who comes into possession of a copy. This 227 License will therefore apply, along with any applicable section 7 228 additional terms, to the whole of the work, and all its parts, 229 regardless of how they are packaged. This License gives no 230 permission to license the work in any other way, but it does not 231 invalidate such permission if you have separately received it. 232 233 d) If the work has interactive user interfaces, each must display 234 Appropriate Legal Notices; however, if the Program has interactive 235 interfaces that do not display Appropriate Legal Notices, your 236 work need not make them do so. 237 238 A compilation of a covered work with other separate and independent 239 works, which are not by their nature extensions of the covered work, 240 and which are not combined with it such as to form a larger program, 241 in or on a volume of a storage or distribution medium, is called an 242 "aggregate" if the compilation and its resulting copyright are not 243 used to limit the access or legal rights of the compilation's users 244 beyond what the individual works permit. Inclusion of a covered work 245 in an aggregate does not cause this License to apply to the other 246 parts of the aggregate. 247 248 6. Conveying Non-Source Forms. 249 250 You may convey a covered work in object code form under the terms 251 of sections 4 and 5, provided that you also convey the 252 machine-readable Corresponding Source under the terms of this License, 253 in one of these ways: 254 255 a) Convey the object code in, or embodied in, a physical product 256 (including a physical distribution medium), accompanied by the 257 Corresponding Source fixed on a durable physical medium 258 customarily used for software interchange. 259 260 b) Convey the object code in, or embodied in, a physical product 261 (including a physical distribution medium), accompanied by a 262 written offer, valid for at least three years and valid for as 263 long as you offer spare parts or customer support for that product 264 model, to give anyone who possesses the object code either (1) a 265 copy of the Corresponding Source for all the software in the 266 product that is covered by this License, on a durable physical 267 medium customarily used for software interchange, for a price no 268 more than your reasonable cost of physically performing this 269 conveying of source, or (2) access to copy the 270 Corresponding Source from a network server at no charge. 271 272 c) Convey individual copies of the object code with a copy of the 273 written offer to provide the Corresponding Source. This 274 alternative is allowed only occasionally and noncommercially, and 275 only if you received the object code with such an offer, in accord 276 with subsection 6b. 277 278 d) Convey the object code by offering access from a designated 279 place (gratis or for a charge), and offer equivalent access to the 280 Corresponding Source in the same way through the same place at no 281 further charge. You need not require recipients to copy the 282 Corresponding Source along with the object code. If the place to 283 copy the object code is a network server, the Corresponding Source 284 may be on a different server (operated by you or a third party) 285 that supports equivalent copying facilities, provided you maintain 286 clear directions next to the object code saying where to find the 287 Corresponding Source. Regardless of what server hosts the 288 Corresponding Source, you remain obligated to ensure that it is 289 available for as long as needed to satisfy these requirements. 290 291 e) Convey the object code using peer-to-peer transmission, provided 292 you inform other peers where the object code and Corresponding 293 Source of the work are being offered to the general public at no 294 charge under subsection 6d. 295 296 A separable portion of the object code, whose source code is excluded 297 from the Corresponding Source as a System Library, need not be 298 included in conveying the object code work. 299 300 A "User Product" is either (1) a "consumer product", which means any 301 tangible personal property which is normally used for personal, family, 302 or household purposes, or (2) anything designed or sold for incorporation 303 into a dwelling. In determining whether a product is a consumer product, 304 doubtful cases shall be resolved in favor of coverage. For a particular 305 product received by a particular user, "normally used" refers to a 306 typical or common use of that class of product, regardless of the status 307 of the particular user or of the way in which the particular user 308 actually uses, or expects or is expected to use, the product. A product 309 is a consumer product regardless of whether the product has substantial 310 commercial, industrial or non-consumer uses, unless such uses represent 311 the only significant mode of use of the product. 312 313 "Installation Information" for a User Product means any methods, 314 procedures, authorization keys, or other information required to install 315 and execute modified versions of a covered work in that User Product from 316 a modified version of its Corresponding Source. The information must 317 suffice to ensure that the continued functioning of the modified object 318 code is in no case prevented or interfered with solely because 319 modification has been made. 320 321 If you convey an object code work under this section in, or with, or 322 specifically for use in, a User Product, and the conveying occurs as 323 part of a transaction in which the right of possession and use of the 324 User Product is transferred to the recipient in perpetuity or for a 325 fixed term (regardless of how the transaction is characterized), the 326 Corresponding Source conveyed under this section must be accompanied 327 by the Installation Information. But this requirement does not apply 328 if neither you nor any third party retains the ability to install 329 modified object code on the User Product (for example, the work has 330 been installed in ROM). 331 332 The requirement to provide Installation Information does not include a 333 requirement to continue to provide support service, warranty, or updates 334 for a work that has been modified or installed by the recipient, or for 335 the User Product in which it has been modified or installed. Access to a 336 network may be denied when the modification itself materially and 337 adversely affects the operation of the network or violates the rules and 338 protocols for communication across the network. 339 340 Corresponding Source conveyed, and Installation Information provided, 341 in accord with this section must be in a format that is publicly 342 documented (and with an implementation available to the public in 343 source code form), and must require no special password or key for 344 unpacking, reading or copying. 345 346 7. Additional Terms. 347 348 "Additional permissions" are terms that supplement the terms of this 349 License by making exceptions from one or more of its conditions. 350 Additional permissions that are applicable to the entire Program shall 351 be treated as though they were included in this License, to the extent 352 that they are valid under applicable law. If additional permissions 353 apply only to part of the Program, that part may be used separately 354 under those permissions, but the entire Program remains governed by 355 this License without regard to the additional permissions. 356 357 When you convey a copy of a covered work, you may at your option 358 remove any additional permissions from that copy, or from any part of 359 it. (Additional permissions may be written to require their own 360 removal in certain cases when you modify the work.) You may place 361 additional permissions on material, added by you to a covered work, 362 for which you have or can give appropriate copyright permission. 363 364 Notwithstanding any other provision of this License, for material you 365 add to a covered work, you may (if authorized by the copyright holders of 366 that material) supplement the terms of this License with terms: 367 368 a) Disclaiming warranty or limiting liability differently from the 369 terms of sections 15 and 16 of this License; or 370 371 b) Requiring preservation of specified reasonable legal notices or 372 author attributions in that material or in the Appropriate Legal 373 Notices displayed by works containing it; or 374 375 c) Prohibiting misrepresentation of the origin of that material, or 376 requiring that modified versions of such material be marked in 377 reasonable ways as different from the original version; or 378 379 d) Limiting the use for publicity purposes of names of licensors or 380 authors of the material; or 381 382 e) Declining to grant rights under trademark law for use of some 383 trade names, trademarks, or service marks; or 384 385 f) Requiring indemnification of licensors and authors of that 386 material by anyone who conveys the material (or modified versions of 387 it) with contractual assumptions of liability to the recipient, for 388 any liability that these contractual assumptions directly impose on 389 those licensors and authors. 390 391 All other non-permissive additional terms are considered "further 392 restrictions" within the meaning of section 10. If the Program as you 393 received it, or any part of it, contains a notice stating that it is 394 governed by this License along with a term that is a further 395 restriction, you may remove that term. If a license document contains 396 a further restriction but permits relicensing or conveying under this 397 License, you may add to a covered work material governed by the terms 398 of that license document, provided that the further restriction does 399 not survive such relicensing or conveying. 400 401 If you add terms to a covered work in accord with this section, you 402 must place, in the relevant source files, a statement of the 403 additional terms that apply to those files, or a notice indicating 404 where to find the applicable terms. 405 406 Additional terms, permissive or non-permissive, may be stated in the 407 form of a separately written license, or stated as exceptions; 408 the above requirements apply either way. 409 410 8. Termination. 411 412 You may not propagate or modify a covered work except as expressly 413 provided under this License. Any attempt otherwise to propagate or 414 modify it is void, and will automatically terminate your rights under 415 this License (including any patent licenses granted under the third 416 paragraph of section 11). 417 418 However, if you cease all violation of this License, then your 419 license from a particular copyright holder is reinstated (a) 420 provisionally, unless and until the copyright holder explicitly and 421 finally terminates your license, and (b) permanently, if the copyright 422 holder fails to notify you of the violation by some reasonable means 423 prior to 60 days after the cessation. 424 425 Moreover, your license from a particular copyright holder is 426 reinstated permanently if the copyright holder notifies you of the 427 violation by some reasonable means, this is the first time you have 428 received notice of violation of this License (for any work) from that 429 copyright holder, and you cure the violation prior to 30 days after 430 your receipt of the notice. 431 432 Termination of your rights under this section does not terminate the 433 licenses of parties who have received copies or rights from you under 434 this License. If your rights have been terminated and not permanently 435 reinstated, you do not qualify to receive new licenses for the same 436 material under section 10. 437 438 9. Acceptance Not Required for Having Copies. 439 440 You are not required to accept this License in order to receive or 441 run a copy of the Program. Ancillary propagation of a covered work 442 occurring solely as a consequence of using peer-to-peer transmission 443 to receive a copy likewise does not require acceptance. However, 444 nothing other than this License grants you permission to propagate or 445 modify any covered work. These actions infringe copyright if you do 446 not accept this License. Therefore, by modifying or propagating a 447 covered work, you indicate your acceptance of this License to do so. 448 449 10. Automatic Licensing of Downstream Recipients. 450 451 Each time you convey a covered work, the recipient automatically 452 receives a license from the original licensors, to run, modify and 453 propagate that work, subject to this License. You are not responsible 454 for enforcing compliance by third parties with this License. 455 456 An "entity transaction" is a transaction transferring control of an 457 organization, or substantially all assets of one, or subdividing an 458 organization, or merging organizations. If propagation of a covered 459 work results from an entity transaction, each party to that 460 transaction who receives a copy of the work also receives whatever 461 licenses to the work the party's predecessor in interest had or could 462 give under the previous paragraph, plus a right to possession of the 463 Corresponding Source of the work from the predecessor in interest, if 464 the predecessor has it or can get it with reasonable efforts. 465 466 You may not impose any further restrictions on the exercise of the 467 rights granted or affirmed under this License. For example, you may 468 not impose a license fee, royalty, or other charge for exercise of 469 rights granted under this License, and you may not initiate litigation 470 (including a cross-claim or counterclaim in a lawsuit) alleging that 471 any patent claim is infringed by making, using, selling, offering for 472 sale, or importing the Program or any portion of it. 473 474 11. Patents. 475 476 A "contributor" is a copyright holder who authorizes use under this 477 License of the Program or a work on which the Program is based. The 478 work thus licensed is called the contributor's "contributor version". 479 480 A contributor's "essential patent claims" are all patent claims 481 owned or controlled by the contributor, whether already acquired or 482 hereafter acquired, that would be infringed by some manner, permitted 483 by this License, of making, using, or selling its contributor version, 484 but do not include claims that would be infringed only as a 485 consequence of further modification of the contributor version. For 486 purposes of this definition, "control" includes the right to grant 487 patent sublicenses in a manner consistent with the requirements of 488 this License. 489 490 Each contributor grants you a non-exclusive, worldwide, royalty-free 491 patent license under the contributor's essential patent claims, to 492 make, use, sell, offer for sale, import and otherwise run, modify and 493 propagate the contents of its contributor version. 494 495 In the following three paragraphs, a "patent license" is any express 496 agreement or commitment, however denominated, not to enforce a patent 497 (such as an express permission to practice a patent or covenant not to 498 sue for patent infringement). To "grant" such a patent license to a 499 party means to make such an agreement or commitment not to enforce a 500 patent against the party. 501 502 If you convey a covered work, knowingly relying on a patent license, 503 and the Corresponding Source of the work is not available for anyone 504 to copy, free of charge and under the terms of this License, through a 505 publicly available network server or other readily accessible means, 506 then you must either (1) cause the Corresponding Source to be so 507 available, or (2) arrange to deprive yourself of the benefit of the 508 patent license for this particular work, or (3) arrange, in a manner 509 consistent with the requirements of this License, to extend the patent 510 license to downstream recipients. "Knowingly relying" means you have 511 actual knowledge that, but for the patent license, your conveying the 512 covered work in a country, or your recipient's use of the covered work 513 in a country, would infringe one or more identifiable patents in that 514 country that you have reason to believe are valid. 515 516 If, pursuant to or in connection with a single transaction or 517 arrangement, you convey, or propagate by procuring conveyance of, a 518 covered work, and grant a patent license to some of the parties 519 receiving the covered work authorizing them to use, propagate, modify 520 or convey a specific copy of the covered work, then the patent license 521 you grant is automatically extended to all recipients of the covered 522 work and works based on it. 523 524 A patent license is "discriminatory" if it does not include within 525 the scope of its coverage, prohibits the exercise of, or is 526 conditioned on the non-exercise of one or more of the rights that are 527 specifically granted under this License. You may not convey a covered 528 work if you are a party to an arrangement with a third party that is 529 in the business of distributing software, under which you make payment 530 to the third party based on the extent of your activity of conveying 531 the work, and under which the third party grants, to any of the 532 parties who would receive the covered work from you, a discriminatory 533 patent license (a) in connection with copies of the covered work 534 conveyed by you (or copies made from those copies), or (b) primarily 535 for and in connection with specific products or compilations that 536 contain the covered work, unless you entered into that arrangement, 537 or that patent license was granted, prior to 28 March 2007. 538 539 Nothing in this License shall be construed as excluding or limiting 540 any implied license or other defenses to infringement that may 541 otherwise be available to you under applicable patent law. 542 543 12. No Surrender of Others' Freedom. 544 545 If conditions are imposed on you (whether by court order, agreement or 546 otherwise) that contradict the conditions of this License, they do not 547 excuse you from the conditions of this License. If you cannot convey a 548 covered work so as to satisfy simultaneously your obligations under this 549 License and any other pertinent obligations, then as a consequence you may 550 not convey it at all. For example, if you agree to terms that obligate you 551 to collect a royalty for further conveying from those to whom you convey 552 the Program, the only way you could satisfy both those terms and this 553 License would be to refrain entirely from conveying the Program. 554 555 13. Use with the GNU Affero General Public License. 556 557 Notwithstanding any other provision of this License, you have 558 permission to link or combine any covered work with a work licensed 559 under version 3 of the GNU Affero General Public License into a single 560 combined work, and to convey the resulting work. The terms of this 561 License will continue to apply to the part which is the covered work, 562 but the special requirements of the GNU Affero General Public License, 563 section 13, concerning interaction through a network will apply to the 564 combination as such. 565 566 14. Revised Versions of this License. 567 568 The Free Software Foundation may publish revised and/or new versions of 569 the GNU General Public License from time to time. Such new versions will 570 be similar in spirit to the present version, but may differ in detail to 571 address new problems or concerns. 572 573 Each version is given a distinguishing version number. If the 574 Program specifies that a certain numbered version of the GNU General 575 Public License "or any later version" applies to it, you have the 576 option of following the terms and conditions either of that numbered 577 version or of any later version published by the Free Software 578 Foundation. If the Program does not specify a version number of the 579 GNU General Public License, you may choose any version ever published 580 by the Free Software Foundation. 581 582 If the Program specifies that a proxy can decide which future 583 versions of the GNU General Public License can be used, that proxy's 584 public statement of acceptance of a version permanently authorizes you 585 to choose that version for the Program. 586 587 Later license versions may give you additional or different 588 permissions. However, no additional obligations are imposed on any 589 author or copyright holder as a result of your choosing to follow a 590 later version. 591 592 15. Disclaimer of Warranty. 593 594 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 595 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 596 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 597 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 598 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 599 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 600 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 601 ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 602 603 16. Limitation of Liability. 604 605 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 606 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 607 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 608 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 609 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 610 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 611 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 612 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 613 SUCH DAMAGES. 614 615 17. Interpretation of Sections 15 and 16. 616 617 If the disclaimer of warranty and limitation of liability provided 618 above cannot be given local legal effect according to their terms, 619 reviewing courts shall apply local law that most closely approximates 620 an absolute waiver of all civil liability in connection with the 621 Program, unless a warranty or assumption of liability accompanies a 622 copy of the Program in return for a fee. 623 624 END OF TERMS AND CONDITIONS 625 626 How to Apply These Terms to Your New Programs 627 628 If you develop a new program, and you want it to be of the greatest 629 possible use to the public, the best way to achieve this is to make it 630 free software which everyone can redistribute and change under these terms. 631 632 To do so, attach the following notices to the program. It is safest 633 to attach them to the start of each source file to most effectively 634 state the exclusion of warranty; and each file should have at least 635 the "copyright" line and a pointer to where the full notice is found. 636 637 <one line to give the program's name and a brief idea of what it does.> 638 Copyright (C) <year> <name of author> 639 640 This program is free software: you can redistribute it and/or modify 641 it under the terms of the GNU General Public License as published by 642 the Free Software Foundation, either version 3 of the License, or 643 (at your option) any later version. 644 645 This program is distributed in the hope that it will be useful, 646 but WITHOUT ANY WARRANTY; without even the implied warranty of 647 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 648 GNU General Public License for more details. 649 650 You should have received a copy of the GNU General Public License 651 along with this program. If not, see <http://www.gnu.org/licenses/>. 652 653 Also add information on how to contact you by electronic and paper mail. 654 655 If the program does terminal interaction, make it output a short 656 notice like this when it starts in an interactive mode: 657 658 <program> Copyright (C) <year> <name of author> 659 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 660 This is free software, and you are welcome to redistribute it 661 under certain conditions; type `show c' for details. 662 663 The hypothetical commands `show w' and `show c' should show the appropriate 664 parts of the General Public License. Of course, your program's commands 665 might be different; for a GUI interface, you would use an "about box". 666 667 You should also get your employer (if you work as a programmer) or school, 668 if any, to sign a "copyright disclaimer" for the program, if necessary. 669 For more information on this, and how to apply and follow the GNU GPL, see 670 <http://www.gnu.org/licenses/>. 671 672 The GNU General Public License does not permit incorporating your program 673 into proprietary programs. If your program is a subroutine library, you 674 may consider it more useful to permit linking proprietary applications with 675 the library. If this is what you want to do, use the GNU Lesser General 676 Public License instead of this License. But first, please read 677 <http://www.gnu.org/philosophy/why-not-lgpl.html>.
