1 GNU GENERAL PUBLIC LICENSE 2 3 The Qt Toolkit is Copyright (C) 2015 The Qt Company Ltd. 4 Contact: http://www.qt.io/licensing/ 5 6 You may use, distribute and copy the Qt Toolkit under the terms of 7 GNU Lesser General Public License version 3. That license references 8 the General Public License version 3, that is displayed below. Other 9 portions of the Qt Toolkit may be licensed directly under this license. 10 11------------------------------------------------------------------------- 12 13 GNU GENERAL PUBLIC LICENSE 14 Version 3, 29 June 2007 15 16 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 17 Everyone is permitted to copy and distribute verbatim copies 18 of this license document, but changing it is not allowed. 19 20 Preamble 21 22 The GNU General Public License is a free, copyleft license for 23software and other kinds of works. 24 25 The licenses for most software and other practical works are designed 26to take away your freedom to share and change the works. By contrast, 27the GNU General Public License is intended to guarantee your freedom to 28share and change all versions of a program--to make sure it remains free 29software for all its users. We, the Free Software Foundation, use the 30GNU General Public License for most of our software; it applies also to 31any other work released this way by its authors. You can apply it to 32your programs, too. 33 34 When we speak of free software, we are referring to freedom, not 35price. Our General Public Licenses are designed to make sure that you 36have the freedom to distribute copies of free software (and charge for 37them if you wish), that you receive source code or can get it if you 38want it, that you can change the software or use pieces of it in new 39free programs, and that you know you can do these things. 40 41 To protect your rights, we need to prevent others from denying you 42these rights or asking you to surrender the rights. Therefore, you have 43certain responsibilities if you distribute copies of the software, or if 44you modify it: responsibilities to respect the freedom of others. 45 46 For example, if you distribute copies of such a program, whether 47gratis or for a fee, you must pass on to the recipients the same 48freedoms that you received. You must make sure that they, too, receive 49or can get the source code. And you must show them these terms so they 50know their rights. 51 52 Developers that use the GNU GPL protect your rights with two steps: 53(1) assert copyright on the software, and (2) offer you this License 54giving you legal permission to copy, distribute and/or modify it. 55 56 For the developers' and authors' protection, the GPL clearly explains 57that there is no warranty for this free software. For both users' and 58authors' sake, the GPL requires that modified versions be marked as 59changed, so that their problems will not be attributed erroneously to 60authors of previous versions. 61 62 Some devices are designed to deny users access to install or run 63modified versions of the software inside them, although the manufacturer 64can do so. This is fundamentally incompatible with the aim of 65protecting users' freedom to change the software. The systematic 66pattern of such abuse occurs in the area of products for individuals to 67use, which is precisely where it is most unacceptable. Therefore, we 68have designed this version of the GPL to prohibit the practice for those 69products. If such problems arise substantially in other domains, we 70stand ready to extend this provision to those domains in future versions 71of the GPL, as needed to protect the freedom of users. 72 73 Finally, every program is threatened constantly by software patents. 74States should not allow patents to restrict development and use of 75software on general-purpose computers, but in those that do, we wish to 76avoid the special danger that patents applied to a free program could 77make it effectively proprietary. To prevent this, the GPL assures that 78patents cannot be used to render the program non-free. 79 80 The precise terms and conditions for copying, distribution and 81modification follow. 82 83 TERMS AND CONDITIONS 84 85 0. Definitions. 86 87 "This License" refers to version 3 of the GNU General Public License. 88 89 "Copyright" also means copyright-like laws that apply to other kinds of 90works, such as semiconductor masks. 91 92 "The Program" refers to any copyrightable work licensed under this 93License. Each licensee is addressed as "you". "Licensees" and 94"recipients" may be individuals or organizations. 95 96 To "modify" a work means to copy from or adapt all or part of the work 97in a fashion requiring copyright permission, other than the making of an 98exact copy. The resulting work is called a "modified version" of the 99earlier work or a work "based on" the earlier work. 100 101 A "covered work" means either the unmodified Program or a work based 102on the Program. 103 104 To "propagate" a work means to do anything with it that, without 105permission, would make you directly or secondarily liable for 106infringement under applicable copyright law, except executing it on a 107computer or modifying a private copy. Propagation includes copying, 108distribution (with or without modification), making available to the 109public, and in some countries other activities as well. 110 111 To "convey" a work means any kind of propagation that enables other 112parties to make or receive copies. Mere interaction with a user through 113a computer network, with no transfer of a copy, is not conveying. 114 115 An interactive user interface displays "Appropriate Legal Notices" 116to the extent that it includes a convenient and prominently visible 117feature that (1) displays an appropriate copyright notice, and (2) 118tells the user that there is no warranty for the work (except to the 119extent that warranties are provided), that licensees may convey the 120work under this License, and how to view a copy of this License. If 121the interface presents a list of user commands or options, such as a 122menu, a prominent item in the list meets this criterion. 123 124 1. Source Code. 125 126 The "source code" for a work means the preferred form of the work 127for making modifications to it. "Object code" means any non-source 128form of a work. 129 130 A "Standard Interface" means an interface that either is an official 131standard defined by a recognized standards body, or, in the case of 132interfaces specified for a particular programming language, one that 133is widely used among developers working in that language. 134 135 The "System Libraries" of an executable work include anything, other 136than the work as a whole, that (a) is included in the normal form of 137packaging a Major Component, but which is not part of that Major 138Component, and (b) serves only to enable use of the work with that 139Major Component, or to implement a Standard Interface for which an 140implementation is available to the public in source code form. A 141"Major Component", in this context, means a major essential component 142(kernel, window system, and so on) of the specific operating system 143(if any) on which the executable work runs, or a compiler used to 144produce the work, or an object code interpreter used to run it. 145 146 The "Corresponding Source" for a work in object code form means all 147the source code needed to generate, install, and (for an executable 148work) run the object code and to modify the work, including scripts to 149control those activities. However, it does not include the work's 150System Libraries, or general-purpose tools or generally available free 151programs which are used unmodified in performing those activities but 152which are not part of the work. For example, Corresponding Source 153includes interface definition files associated with source files for 154the work, and the source code for shared libraries and dynamically 155linked subprograms that the work is specifically designed to require, 156such as by intimate data communication or control flow between those 157subprograms and other parts of the work. 158 159 The Corresponding Source need not include anything that users 160can regenerate automatically from other parts of the Corresponding 161Source. 162 163 The Corresponding Source for a work in source code form is that 164same work. 165 166 2. Basic Permissions. 167 168 All rights granted under this License are granted for the term of 169copyright on the Program, and are irrevocable provided the stated 170conditions are met. This License explicitly affirms your unlimited 171permission to run the unmodified Program. The output from running a 172covered work is covered by this License only if the output, given its 173content, constitutes a covered work. This License acknowledges your 174rights of fair use or other equivalent, as provided by copyright law. 175 176 You may make, run and propagate covered works that you do not 177convey, without conditions so long as your license otherwise remains 178in force. You may convey covered works to others for the sole purpose 179of having them make modifications exclusively for you, or provide you 180with facilities for running those works, provided that you comply with 181the terms of this License in conveying all material for which you do 182not control copyright. Those thus making or running the covered works 183for you must do so exclusively on your behalf, under your direction 184and control, on terms that prohibit them from making any copies of 185your copyrighted material outside their relationship with you. 186 187 Conveying under any other circumstances is permitted solely under 188the conditions stated below. Sublicensing is not allowed; section 10 189makes it unnecessary. 190 191 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 192 193 No covered work shall be deemed part of an effective technological 194measure under any applicable law fulfilling obligations under article 19511 of the WIPO copyright treaty adopted on 20 December 1996, or 196similar laws prohibiting or restricting circumvention of such 197measures. 198 199 When you convey a covered work, you waive any legal power to forbid 200circumvention of technological measures to the extent such circumvention 201is effected by exercising rights under this License with respect to 202the covered work, and you disclaim any intention to limit operation or 203modification of the work as a means of enforcing, against the work's 204users, your or third parties' legal rights to forbid circumvention of 205technological measures. 206 207 4. Conveying Verbatim Copies. 208 209 You may convey verbatim copies of the Program's source code as you 210receive it, in any medium, provided that you conspicuously and 211appropriately publish on each copy an appropriate copyright notice; 212keep intact all notices stating that this License and any 213non-permissive terms added in accord with section 7 apply to the code; 214keep intact all notices of the absence of any warranty; and give all 215recipients a copy of this License along with the Program. 216 217 You may charge any price or no price for each copy that you convey, 218and you may offer support or warranty protection for a fee. 219 220 5. Conveying Modified Source Versions. 221 222 You may convey a work based on the Program, or the modifications to 223produce it from the Program, in the form of source code under the 224terms of section 4, provided that you also meet all of these conditions: 225 226 a) The work must carry prominent notices stating that you modified 227 it, and giving a relevant date. 228 229 b) The work must carry prominent notices stating that it is 230 released under this License and any conditions added under section 231 7. This requirement modifies the requirement in section 4 to 232 "keep intact all notices". 233 234 c) You must license the entire work, as a whole, under this 235 License to anyone who comes into possession of a copy. This 236 License will therefore apply, along with any applicable section 7 237 additional terms, to the whole of the work, and all its parts, 238 regardless of how they are packaged. This License gives no 239 permission to license the work in any other way, but it does not 240 invalidate such permission if you have separately received it. 241 242 d) If the work has interactive user interfaces, each must display 243 Appropriate Legal Notices; however, if the Program has interactive 244 interfaces that do not display Appropriate Legal Notices, your 245 work need not make them do so. 246 247 A compilation of a covered work with other separate and independent 248works, which are not by their nature extensions of the covered work, 249and which are not combined with it such as to form a larger program, 250in or on a volume of a storage or distribution medium, is called an 251"aggregate" if the compilation and its resulting copyright are not 252used to limit the access or legal rights of the compilation's users 253beyond what the individual works permit. Inclusion of a covered work 254in an aggregate does not cause this License to apply to the other 255parts of the aggregate. 256 257 6. Conveying Non-Source Forms. 258 259 You may convey a covered work in object code form under the terms 260of sections 4 and 5, provided that you also convey the 261machine-readable Corresponding Source under the terms of this License, 262in one of these ways: 263 264 a) Convey the object code in, or embodied in, a physical product 265 (including a physical distribution medium), accompanied by the 266 Corresponding Source fixed on a durable physical medium 267 customarily used for software interchange. 268 269 b) Convey the object code in, or embodied in, a physical product 270 (including a physical distribution medium), accompanied by a 271 written offer, valid for at least three years and valid for as 272 long as you offer spare parts or customer support for that product 273 model, to give anyone who possesses the object code either (1) a 274 copy of the Corresponding Source for all the software in the 275 product that is covered by this License, on a durable physical 276 medium customarily used for software interchange, for a price no 277 more than your reasonable cost of physically performing this 278 conveying of source, or (2) access to copy the 279 Corresponding Source from a network server at no charge. 280 281 c) Convey individual copies of the object code with a copy of the 282 written offer to provide the Corresponding Source. This 283 alternative is allowed only occasionally and noncommercially, and 284 only if you received the object code with such an offer, in accord 285 with subsection 6b. 286 287 d) Convey the object code by offering access from a designated 288 place (gratis or for a charge), and offer equivalent access to the 289 Corresponding Source in the same way through the same place at no 290 further charge. You need not require recipients to copy the 291 Corresponding Source along with the object code. If the place to 292 copy the object code is a network server, the Corresponding Source 293 may be on a different server (operated by you or a third party) 294 that supports equivalent copying facilities, provided you maintain 295 clear directions next to the object code saying where to find the 296 Corresponding Source. Regardless of what server hosts the 297 Corresponding Source, you remain obligated to ensure that it is 298 available for as long as needed to satisfy these requirements. 299 300 e) Convey the object code using peer-to-peer transmission, provided 301 you inform other peers where the object code and Corresponding 302 Source of the work are being offered to the general public at no 303 charge under subsection 6d. 304 305 A separable portion of the object code, whose source code is excluded 306from the Corresponding Source as a System Library, need not be 307included in conveying the object code work. 308 309 A "User Product" is either (1) a "consumer product", which means any 310tangible personal property which is normally used for personal, family, 311or household purposes, or (2) anything designed or sold for incorporation 312into a dwelling. In determining whether a product is a consumer product, 313doubtful cases shall be resolved in favor of coverage. For a particular 314product received by a particular user, "normally used" refers to a 315typical or common use of that class of product, regardless of the status 316of the particular user or of the way in which the particular user 317actually uses, or expects or is expected to use, the product. A product 318is a consumer product regardless of whether the product has substantial 319commercial, industrial or non-consumer uses, unless such uses represent 320the only significant mode of use of the product. 321 322 "Installation Information" for a User Product means any methods, 323procedures, authorization keys, or other information required to install 324and execute modified versions of a covered work in that User Product from 325a modified version of its Corresponding Source. The information must 326suffice to ensure that the continued functioning of the modified object 327code is in no case prevented or interfered with solely because 328modification has been made. 329 330 If you convey an object code work under this section in, or with, or 331specifically for use in, a User Product, and the conveying occurs as 332part of a transaction in which the right of possession and use of the 333User Product is transferred to the recipient in perpetuity or for a 334fixed term (regardless of how the transaction is characterized), the 335Corresponding Source conveyed under this section must be accompanied 336by the Installation Information. But this requirement does not apply 337if neither you nor any third party retains the ability to install 338modified object code on the User Product (for example, the work has 339been installed in ROM). 340 341 The requirement to provide Installation Information does not include a 342requirement to continue to provide support service, warranty, or updates 343for a work that has been modified or installed by the recipient, or for 344the User Product in which it has been modified or installed. Access to a 345network may be denied when the modification itself materially and 346adversely affects the operation of the network or violates the rules and 347protocols for communication across the network. 348 349 Corresponding Source conveyed, and Installation Information provided, 350in accord with this section must be in a format that is publicly 351documented (and with an implementation available to the public in 352source code form), and must require no special password or key for 353unpacking, reading or copying. 354 355 7. Additional Terms. 356 357 "Additional permissions" are terms that supplement the terms of this 358License by making exceptions from one or more of its conditions. 359Additional permissions that are applicable to the entire Program shall 360be treated as though they were included in this License, to the extent 361that they are valid under applicable law. If additional permissions 362apply only to part of the Program, that part may be used separately 363under those permissions, but the entire Program remains governed by 364this License without regard to the additional permissions. 365 366 When you convey a copy of a covered work, you may at your option 367remove any additional permissions from that copy, or from any part of 368it. (Additional permissions may be written to require their own 369removal in certain cases when you modify the work.) You may place 370additional permissions on material, added by you to a covered work, 371for which you have or can give appropriate copyright permission. 372 373 Notwithstanding any other provision of this License, for material you 374add to a covered work, you may (if authorized by the copyright holders of 375that material) supplement the terms of this License with terms: 376 377 a) Disclaiming warranty or limiting liability differently from the 378 terms of sections 15 and 16 of this License; or 379 380 b) Requiring preservation of specified reasonable legal notices or 381 author attributions in that material or in the Appropriate Legal 382 Notices displayed by works containing it; or 383 384 c) Prohibiting misrepresentation of the origin of that material, or 385 requiring that modified versions of such material be marked in 386 reasonable ways as different from the original version; or 387 388 d) Limiting the use for publicity purposes of names of licensors or 389 authors of the material; or 390 391 e) Declining to grant rights under trademark law for use of some 392 trade names, trademarks, or service marks; or 393 394 f) Requiring indemnification of licensors and authors of that 395 material by anyone who conveys the material (or modified versions of 396 it) with contractual assumptions of liability to the recipient, for 397 any liability that these contractual assumptions directly impose on 398 those licensors and authors. 399 400 All other non-permissive additional terms are considered "further 401restrictions" within the meaning of section 10. If the Program as you 402received it, or any part of it, contains a notice stating that it is 403governed by this License along with a term that is a further 404restriction, you may remove that term. If a license document contains 405a further restriction but permits relicensing or conveying under this 406License, you may add to a covered work material governed by the terms 407of that license document, provided that the further restriction does 408not survive such relicensing or conveying. 409 410 If you add terms to a covered work in accord with this section, you 411must place, in the relevant source files, a statement of the 412additional terms that apply to those files, or a notice indicating 413where to find the applicable terms. 414 415 Additional terms, permissive or non-permissive, may be stated in the 416form of a separately written license, or stated as exceptions; 417the above requirements apply either way. 418 419 8. Termination. 420 421 You may not propagate or modify a covered work except as expressly 422provided under this License. Any attempt otherwise to propagate or 423modify it is void, and will automatically terminate your rights under 424this License (including any patent licenses granted under the third 425paragraph of section 11). 426 427 However, if you cease all violation of this License, then your 428license from a particular copyright holder is reinstated (a) 429provisionally, unless and until the copyright holder explicitly and 430finally terminates your license, and (b) permanently, if the copyright 431holder fails to notify you of the violation by some reasonable means 432prior to 60 days after the cessation. 433 434 Moreover, your license from a particular copyright holder is 435reinstated permanently if the copyright holder notifies you of the 436violation by some reasonable means, this is the first time you have 437received notice of violation of this License (for any work) from that 438copyright holder, and you cure the violation prior to 30 days after 439your receipt of the notice. 440 441 Termination of your rights under this section does not terminate the 442licenses of parties who have received copies or rights from you under 443this License. If your rights have been terminated and not permanently 444reinstated, you do not qualify to receive new licenses for the same 445material under section 10. 446 447 9. Acceptance Not Required for Having Copies. 448 449 You are not required to accept this License in order to receive or 450run a copy of the Program. Ancillary propagation of a covered work 451occurring solely as a consequence of using peer-to-peer transmission 452to receive a copy likewise does not require acceptance. However, 453nothing other than this License grants you permission to propagate or 454modify any covered work. These actions infringe copyright if you do 455not accept this License. Therefore, by modifying or propagating a 456covered work, you indicate your acceptance of this License to do so. 457 458 10. Automatic Licensing of Downstream Recipients. 459 460 Each time you convey a covered work, the recipient automatically 461receives a license from the original licensors, to run, modify and 462propagate that work, subject to this License. You are not responsible 463for enforcing compliance by third parties with this License. 464 465 An "entity transaction" is a transaction transferring control of an 466organization, or substantially all assets of one, or subdividing an 467organization, or merging organizations. If propagation of a covered 468work results from an entity transaction, each party to that 469transaction who receives a copy of the work also receives whatever 470licenses to the work the party's predecessor in interest had or could 471give under the previous paragraph, plus a right to possession of the 472Corresponding Source of the work from the predecessor in interest, if 473the predecessor has it or can get it with reasonable efforts. 474 475 You may not impose any further restrictions on the exercise of the 476rights granted or affirmed under this License. For example, you may 477not impose a license fee, royalty, or other charge for exercise of 478rights granted under this License, and you may not initiate litigation 479(including a cross-claim or counterclaim in a lawsuit) alleging that 480any patent claim is infringed by making, using, selling, offering for 481sale, or importing the Program or any portion of it. 482 483 11. Patents. 484 485 A "contributor" is a copyright holder who authorizes use under this 486License of the Program or a work on which the Program is based. The 487work thus licensed is called the contributor's "contributor version". 488 489 A contributor's "essential patent claims" are all patent claims 490owned or controlled by the contributor, whether already acquired or 491hereafter acquired, that would be infringed by some manner, permitted 492by this License, of making, using, or selling its contributor version, 493but do not include claims that would be infringed only as a 494consequence of further modification of the contributor version. For 495purposes of this definition, "control" includes the right to grant 496patent sublicenses in a manner consistent with the requirements of 497this License. 498 499 Each contributor grants you a non-exclusive, worldwide, royalty-free 500patent license under the contributor's essential patent claims, to 501make, use, sell, offer for sale, import and otherwise run, modify and 502propagate the contents of its contributor version. 503 504 In the following three paragraphs, a "patent license" is any express 505agreement or commitment, however denominated, not to enforce a patent 506(such as an express permission to practice a patent or covenant not to 507sue for patent infringement). To "grant" such a patent license to a 508party means to make such an agreement or commitment not to enforce a 509patent against the party. 510 511 If you convey a covered work, knowingly relying on a patent license, 512and the Corresponding Source of the work is not available for anyone 513to copy, free of charge and under the terms of this License, through a 514publicly available network server or other readily accessible means, 515then you must either (1) cause the Corresponding Source to be so 516available, or (2) arrange to deprive yourself of the benefit of the 517patent license for this particular work, or (3) arrange, in a manner 518consistent with the requirements of this License, to extend the patent 519license to downstream recipients. "Knowingly relying" means you have 520actual knowledge that, but for the patent license, your conveying the 521covered work in a country, or your recipient's use of the covered work 522in a country, would infringe one or more identifiable patents in that 523country that you have reason to believe are valid. 524 525 If, pursuant to or in connection with a single transaction or 526arrangement, you convey, or propagate by procuring conveyance of, a 527covered work, and grant a patent license to some of the parties 528receiving the covered work authorizing them to use, propagate, modify 529or convey a specific copy of the covered work, then the patent license 530you grant is automatically extended to all recipients of the covered 531work and works based on it. 532 533 A patent license is "discriminatory" if it does not include within 534the scope of its coverage, prohibits the exercise of, or is 535conditioned on the non-exercise of one or more of the rights that are 536specifically granted under this License. You may not convey a covered 537work if you are a party to an arrangement with a third party that is 538in the business of distributing software, under which you make payment 539to the third party based on the extent of your activity of conveying 540the work, and under which the third party grants, to any of the 541parties who would receive the covered work from you, a discriminatory 542patent license (a) in connection with copies of the covered work 543conveyed by you (or copies made from those copies), or (b) primarily 544for and in connection with specific products or compilations that 545contain the covered work, unless you entered into that arrangement, 546or that patent license was granted, prior to 28 March 2007. 547 548 Nothing in this License shall be construed as excluding or limiting 549any implied license or other defenses to infringement that may 550otherwise be available to you under applicable patent law. 551 552 12. No Surrender of Others' Freedom. 553 554 If conditions are imposed on you (whether by court order, agreement or 555otherwise) that contradict the conditions of this License, they do not 556excuse you from the conditions of this License. If you cannot convey a 557covered work so as to satisfy simultaneously your obligations under this 558License and any other pertinent obligations, then as a consequence you may 559not convey it at all. For example, if you agree to terms that obligate you 560to collect a royalty for further conveying from those to whom you convey 561the Program, the only way you could satisfy both those terms and this 562License would be to refrain entirely from conveying the Program. 563 564 13. Use with the GNU Affero General Public License. 565 566 Notwithstanding any other provision of this License, you have 567permission to link or combine any covered work with a work licensed 568under version 3 of the GNU Affero General Public License into a single 569combined work, and to convey the resulting work. The terms of this 570License will continue to apply to the part which is the covered work, 571but the special requirements of the GNU Affero General Public License, 572section 13, concerning interaction through a network will apply to the 573combination as such. 574 575 14. Revised Versions of this License. 576 577 The Free Software Foundation may publish revised and/or new versions of 578the GNU General Public License from time to time. Such new versions will 579be similar in spirit to the present version, but may differ in detail to 580address new problems or concerns. 581 582 Each version is given a distinguishing version number. If the 583Program specifies that a certain numbered version of the GNU General 584Public License "or any later version" applies to it, you have the 585option of following the terms and conditions either of that numbered 586version or of any later version published by the Free Software 587Foundation. If the Program does not specify a version number of the 588GNU General Public License, you may choose any version ever published 589by the Free Software Foundation. 590 591 If the Program specifies that a proxy can decide which future 592versions of the GNU General Public License can be used, that proxy's 593public statement of acceptance of a version permanently authorizes you 594to choose that version for the Program. 595 596 Later license versions may give you additional or different 597permissions. However, no additional obligations are imposed on any 598author or copyright holder as a result of your choosing to follow a 599later version. 600 601 15. Disclaimer of Warranty. 602 603 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 604APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 605HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 606OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 607THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 608PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 609IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 610ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 611 612 16. Limitation of Liability. 613 614 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 615WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 616THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 617GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 618USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 619DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 620PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 621EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 622SUCH DAMAGES. 623 624 17. Interpretation of Sections 15 and 16. 625 626 If the disclaimer of warranty and limitation of liability provided 627above cannot be given local legal effect according to their terms, 628reviewing courts shall apply local law that most closely approximates 629an absolute waiver of all civil liability in connection with the 630Program, unless a warranty or assumption of liability accompanies a 631copy of the Program in return for a fee. 632 633 END OF TERMS AND CONDITIONS 634 635 How to Apply These Terms to Your New Programs 636 637 If you develop a new program, and you want it to be of the greatest 638possible use to the public, the best way to achieve this is to make it 639free software which everyone can redistribute and change under these terms. 640 641 To do so, attach the following notices to the program. It is safest 642to attach them to the start of each source file to most effectively 643state the exclusion of warranty; and each file should have at least 644the "copyright" line and a pointer to where the full notice is found. 645 646 <one line to give the program's name and a brief idea of what it does.> 647 Copyright (C) <year> <name of author> 648 649 This program is free software: you can redistribute it and/or modify 650 it under the terms of the GNU General Public License as published by 651 the Free Software Foundation, either version 3 of the License, or 652 (at your option) any later version. 653 654 This program is distributed in the hope that it will be useful, 655 but WITHOUT ANY WARRANTY; without even the implied warranty of 656 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 657 GNU General Public License for more details. 658 659 You should have received a copy of the GNU General Public License 660 along with this program. If not, see <http://www.gnu.org/licenses/>. 661 662Also add information on how to contact you by electronic and paper mail. 663 664 If the program does terminal interaction, make it output a short 665notice like this when it starts in an interactive mode: 666 667 <program> Copyright (C) <year> <name of author> 668 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 669 This is free software, and you are welcome to redistribute it 670 under certain conditions; type `show c' for details. 671 672The hypothetical commands `show w' and `show c' should show the appropriate 673parts of the General Public License. Of course, your program's commands 674might be different; for a GUI interface, you would use an "about box". 675 676 You should also get your employer (if you work as a programmer) or school, 677if any, to sign a "copyright disclaimer" for the program, if necessary. 678For more information on this, and how to apply and follow the GNU GPL, see 679<http://www.gnu.org/licenses/>. 680 681 The GNU General Public License does not permit incorporating your program 682into proprietary programs. If your program is a subroutine library, you 683may consider it more useful to permit linking proprietary applications with 684the library. If this is what you want to do, use the GNU Lesser General 685Public License instead of this License. But first, please read 686<http://www.gnu.org/philosophy/why-not-lgpl.html>. 687
