0001 GNU GENERAL PUBLIC LICENSE 0002 Version 3, 29 June 2007 0003 0004 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/> 0005 Everyone is permitted to copy and distribute verbatim copies 0006 of this license document, but changing it is not allowed. 0007 0008 Preamble 0009 0010 The GNU General Public License is a free, copyleft license for 0011 software and other kinds of works. 0012 0013 The licenses for most software and other practical works are designed 0014 to take away your freedom to share and change the works. By contrast, 0015 the GNU General Public License is intended to guarantee your freedom to 0016 share and change all versions of a program--to make sure it remains free 0017 software for all its users. We, the Free Software Foundation, use the 0018 GNU General Public License for most of our software; it applies also to 0019 any other work released this way by its authors. You can apply it to 0020 your programs, too. 0021 0022 When we speak of free software, we are referring to freedom, not 0023 price. Our General Public Licenses are designed to make sure that you 0024 have the freedom to distribute copies of free software (and charge for 0025 them if you wish), that you receive source code or can get it if you 0026 want it, that you can change the software or use pieces of it in new 0027 free programs, and that you know you can do these things. 0028 0029 To protect your rights, we need to prevent others from denying you 0030 these rights or asking you to surrender the rights. Therefore, you have 0031 certain responsibilities if you distribute copies of the software, or if 0032 you modify it: responsibilities to respect the freedom of others. 0033 0034 For example, if you distribute copies of such a program, whether 0035 gratis or for a fee, you must pass on to the recipients the same 0036 freedoms that you received. You must make sure that they, too, receive 0037 or can get the source code. And you must show them these terms so they 0038 know their rights. 0039 0040 Developers that use the GNU GPL protect your rights with two steps: 0041 (1) assert copyright on the software, and (2) offer you this License 0042 giving you legal permission to copy, distribute and/or modify it. 0043 0044 For the developers' and authors' protection, the GPL clearly explains 0045 that there is no warranty for this free software. For both users' and 0046 authors' sake, the GPL requires that modified versions be marked as 0047 changed, so that their problems will not be attributed erroneously to 0048 authors of previous versions. 0049 0050 Some devices are designed to deny users access to install or run 0051 modified versions of the software inside them, although the manufacturer 0052 can do so. This is fundamentally incompatible with the aim of 0053 protecting users' freedom to change the software. The systematic 0054 pattern of such abuse occurs in the area of products for individuals to 0055 use, which is precisely where it is most unacceptable. Therefore, we 0056 have designed this version of the GPL to prohibit the practice for those 0057 products. If such problems arise substantially in other domains, we 0058 stand ready to extend this provision to those domains in future versions 0059 of the GPL, as needed to protect the freedom of users. 0060 0061 Finally, every program is threatened constantly by software patents. 0062 States should not allow patents to restrict development and use of 0063 software on general-purpose computers, but in those that do, we wish to 0064 avoid the special danger that patents applied to a free program could 0065 make it effectively proprietary. To prevent this, the GPL assures that 0066 patents cannot be used to render the program non-free. 0067 0068 The precise terms and conditions for copying, distribution and 0069 modification follow. 0070 0071 TERMS AND CONDITIONS 0072 0073 0. Definitions. 0074 0075 "This License" refers to version 3 of the GNU General Public License. 0076 0077 "Copyright" also means copyright-like laws that apply to other kinds of 0078 works, such as semiconductor masks. 0079 0080 "The Program" refers to any copyrightable work licensed under this 0081 License. Each licensee is addressed as "you". "Licensees" and 0082 "recipients" may be individuals or organizations. 0083 0084 To "modify" a work means to copy from or adapt all or part of the work 0085 in a fashion requiring copyright permission, other than the making of an 0086 exact copy. The resulting work is called a "modified version" of the 0087 earlier work or a work "based on" the earlier work. 0088 0089 A "covered work" means either the unmodified Program or a work based 0090 on the Program. 0091 0092 To "propagate" a work means to do anything with it that, without 0093 permission, would make you directly or secondarily liable for 0094 infringement under applicable copyright law, except executing it on a 0095 computer or modifying a private copy. Propagation includes copying, 0096 distribution (with or without modification), making available to the 0097 public, and in some countries other activities as well. 0098 0099 To "convey" a work means any kind of propagation that enables other 0100 parties to make or receive copies. Mere interaction with a user through 0101 a computer network, with no transfer of a copy, is not conveying. 0102 0103 An interactive user interface displays "Appropriate Legal Notices" 0104 to the extent that it includes a convenient and prominently visible 0105 feature that (1) displays an appropriate copyright notice, and (2) 0106 tells the user that there is no warranty for the work (except to the 0107 extent that warranties are provided), that licensees may convey the 0108 work under this License, and how to view a copy of this License. If 0109 the interface presents a list of user commands or options, such as a 0110 menu, a prominent item in the list meets this criterion. 0111 0112 1. Source Code. 0113 0114 The "source code" for a work means the preferred form of the work 0115 for making modifications to it. "Object code" means any non-source 0116 form of a work. 0117 0118 A "Standard Interface" means an interface that either is an official 0119 standard defined by a recognized standards body, or, in the case of 0120 interfaces specified for a particular programming language, one that 0121 is widely used among developers working in that language. 0122 0123 The "System Libraries" of an executable work include anything, other 0124 than the work as a whole, that (a) is included in the normal form of 0125 packaging a Major Component, but which is not part of that Major 0126 Component, and (b) serves only to enable use of the work with that 0127 Major Component, or to implement a Standard Interface for which an 0128 implementation is available to the public in source code form. A 0129 "Major Component", in this context, means a major essential component 0130 (kernel, window system, and so on) of the specific operating system 0131 (if any) on which the executable work runs, or a compiler used to 0132 produce the work, or an object code interpreter used to run it. 0133 0134 The "Corresponding Source" for a work in object code form means all 0135 the source code needed to generate, install, and (for an executable 0136 work) run the object code and to modify the work, including scripts to 0137 control those activities. However, it does not include the work's 0138 System Libraries, or general-purpose tools or generally available free 0139 programs which are used unmodified in performing those activities but 0140 which are not part of the work. For example, Corresponding Source 0141 includes interface definition files associated with source files for 0142 the work, and the source code for shared libraries and dynamically 0143 linked subprograms that the work is specifically designed to require, 0144 such as by intimate data communication or control flow between those 0145 subprograms and other parts of the work. 0146 0147 The Corresponding Source need not include anything that users 0148 can regenerate automatically from other parts of the Corresponding 0149 Source. 0150 0151 The Corresponding Source for a work in source code form is that 0152 same work. 0153 0154 2. Basic Permissions. 0155 0156 All rights granted under this License are granted for the term of 0157 copyright on the Program, and are irrevocable provided the stated 0158 conditions are met. This License explicitly affirms your unlimited 0159 permission to run the unmodified Program. The output from running a 0160 covered work is covered by this License only if the output, given its 0161 content, constitutes a covered work. This License acknowledges your 0162 rights of fair use or other equivalent, as provided by copyright law. 0163 0164 You may make, run and propagate covered works that you do not 0165 convey, without conditions so long as your license otherwise remains 0166 in force. You may convey covered works to others for the sole purpose 0167 of having them make modifications exclusively for you, or provide you 0168 with facilities for running those works, provided that you comply with 0169 the terms of this License in conveying all material for which you do 0170 not control copyright. Those thus making or running the covered works 0171 for you must do so exclusively on your behalf, under your direction 0172 and control, on terms that prohibit them from making any copies of 0173 your copyrighted material outside their relationship with you. 0174 0175 Conveying under any other circumstances is permitted solely under 0176 the conditions stated below. Sublicensing is not allowed; section 10 0177 makes it unnecessary. 0178 0179 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 0180 0181 No covered work shall be deemed part of an effective technological 0182 measure under any applicable law fulfilling obligations under article 0183 11 of the WIPO copyright treaty adopted on 20 December 1996, or 0184 similar laws prohibiting or restricting circumvention of such 0185 measures. 0186 0187 When you convey a covered work, you waive any legal power to forbid 0188 circumvention of technological measures to the extent such circumvention 0189 is effected by exercising rights under this License with respect to 0190 the covered work, and you disclaim any intention to limit operation or 0191 modification of the work as a means of enforcing, against the work's 0192 users, your or third parties' legal rights to forbid circumvention of 0193 technological measures. 0194 0195 4. Conveying Verbatim Copies. 0196 0197 You may convey verbatim copies of the Program's source code as you 0198 receive it, in any medium, provided that you conspicuously and 0199 appropriately publish on each copy an appropriate copyright notice; 0200 keep intact all notices stating that this License and any 0201 non-permissive terms added in accord with section 7 apply to the code; 0202 keep intact all notices of the absence of any warranty; and give all 0203 recipients a copy of this License along with the Program. 0204 0205 You may charge any price or no price for each copy that you convey, 0206 and you may offer support or warranty protection for a fee. 0207 0208 5. Conveying Modified Source Versions. 0209 0210 You may convey a work based on the Program, or the modifications to 0211 produce it from the Program, in the form of source code under the 0212 terms of section 4, provided that you also meet all of these conditions: 0213 0214 a) The work must carry prominent notices stating that you modified 0215 it, and giving a relevant date. 0216 0217 b) The work must carry prominent notices stating that it is 0218 released under this License and any conditions added under section 0219 7. This requirement modifies the requirement in section 4 to 0220 "keep intact all notices". 0221 0222 c) You must license the entire work, as a whole, under this 0223 License to anyone who comes into possession of a copy. This 0224 License will therefore apply, along with any applicable section 7 0225 additional terms, to the whole of the work, and all its parts, 0226 regardless of how they are packaged. This License gives no 0227 permission to license the work in any other way, but it does not 0228 invalidate such permission if you have separately received it. 0229 0230 d) If the work has interactive user interfaces, each must display 0231 Appropriate Legal Notices; however, if the Program has interactive 0232 interfaces that do not display Appropriate Legal Notices, your 0233 work need not make them do so. 0234 0235 A compilation of a covered work with other separate and independent 0236 works, which are not by their nature extensions of the covered work, 0237 and which are not combined with it such as to form a larger program, 0238 in or on a volume of a storage or distribution medium, is called an 0239 "aggregate" if the compilation and its resulting copyright are not 0240 used to limit the access or legal rights of the compilation's users 0241 beyond what the individual works permit. Inclusion of a covered work 0242 in an aggregate does not cause this License to apply to the other 0243 parts of the aggregate. 0244 0245 6. Conveying Non-Source Forms. 0246 0247 You may convey a covered work in object code form under the terms 0248 of sections 4 and 5, provided that you also convey the 0249 machine-readable Corresponding Source under the terms of this License, 0250 in one of these ways: 0251 0252 a) Convey the object code in, or embodied in, a physical product 0253 (including a physical distribution medium), accompanied by the 0254 Corresponding Source fixed on a durable physical medium 0255 customarily used for software interchange. 0256 0257 b) Convey the object code in, or embodied in, a physical product 0258 (including a physical distribution medium), accompanied by a 0259 written offer, valid for at least three years and valid for as 0260 long as you offer spare parts or customer support for that product 0261 model, to give anyone who possesses the object code either (1) a 0262 copy of the Corresponding Source for all the software in the 0263 product that is covered by this License, on a durable physical 0264 medium customarily used for software interchange, for a price no 0265 more than your reasonable cost of physically performing this 0266 conveying of source, or (2) access to copy the 0267 Corresponding Source from a network server at no charge. 0268 0269 c) Convey individual copies of the object code with a copy of the 0270 written offer to provide the Corresponding Source. This 0271 alternative is allowed only occasionally and noncommercially, and 0272 only if you received the object code with such an offer, in accord 0273 with subsection 6b. 0274 0275 d) Convey the object code by offering access from a designated 0276 place (gratis or for a charge), and offer equivalent access to the 0277 Corresponding Source in the same way through the same place at no 0278 further charge. You need not require recipients to copy the 0279 Corresponding Source along with the object code. If the place to 0280 copy the object code is a network server, the Corresponding Source 0281 may be on a different server (operated by you or a third party) 0282 that supports equivalent copying facilities, provided you maintain 0283 clear directions next to the object code saying where to find the 0284 Corresponding Source. Regardless of what server hosts the 0285 Corresponding Source, you remain obligated to ensure that it is 0286 available for as long as needed to satisfy these requirements. 0287 0288 e) Convey the object code using peer-to-peer transmission, provided 0289 you inform other peers where the object code and Corresponding 0290 Source of the work are being offered to the general public at no 0291 charge under subsection 6d. 0292 0293 A separable portion of the object code, whose source code is excluded 0294 from the Corresponding Source as a System Library, need not be 0295 included in conveying the object code work. 0296 0297 A "User Product" is either (1) a "consumer product", which means any 0298 tangible personal property which is normally used for personal, family, 0299 or household purposes, or (2) anything designed or sold for incorporation 0300 into a dwelling. In determining whether a product is a consumer product, 0301 doubtful cases shall be resolved in favor of coverage. For a particular 0302 product received by a particular user, "normally used" refers to a 0303 typical or common use of that class of product, regardless of the status 0304 of the particular user or of the way in which the particular user 0305 actually uses, or expects or is expected to use, the product. A product 0306 is a consumer product regardless of whether the product has substantial 0307 commercial, industrial or non-consumer uses, unless such uses represent 0308 the only significant mode of use of the product. 0309 0310 "Installation Information" for a User Product means any methods, 0311 procedures, authorization keys, or other information required to install 0312 and execute modified versions of a covered work in that User Product from 0313 a modified version of its Corresponding Source. The information must 0314 suffice to ensure that the continued functioning of the modified object 0315 code is in no case prevented or interfered with solely because 0316 modification has been made. 0317 0318 If you convey an object code work under this section in, or with, or 0319 specifically for use in, a User Product, and the conveying occurs as 0320 part of a transaction in which the right of possession and use of the 0321 User Product is transferred to the recipient in perpetuity or for a 0322 fixed term (regardless of how the transaction is characterized), the 0323 Corresponding Source conveyed under this section must be accompanied 0324 by the Installation Information. But this requirement does not apply 0325 if neither you nor any third party retains the ability to install 0326 modified object code on the User Product (for example, the work has 0327 been installed in ROM). 0328 0329 The requirement to provide Installation Information does not include a 0330 requirement to continue to provide support service, warranty, or updates 0331 for a work that has been modified or installed by the recipient, or for 0332 the User Product in which it has been modified or installed. Access to a 0333 network may be denied when the modification itself materially and 0334 adversely affects the operation of the network or violates the rules and 0335 protocols for communication across the network. 0336 0337 Corresponding Source conveyed, and Installation Information provided, 0338 in accord with this section must be in a format that is publicly 0339 documented (and with an implementation available to the public in 0340 source code form), and must require no special password or key for 0341 unpacking, reading or copying. 0342 0343 7. Additional Terms. 0344 0345 "Additional permissions" are terms that supplement the terms of this 0346 License by making exceptions from one or more of its conditions. 0347 Additional permissions that are applicable to the entire Program shall 0348 be treated as though they were included in this License, to the extent 0349 that they are valid under applicable law. If additional permissions 0350 apply only to part of the Program, that part may be used separately 0351 under those permissions, but the entire Program remains governed by 0352 this License without regard to the additional permissions. 0353 0354 When you convey a copy of a covered work, you may at your option 0355 remove any additional permissions from that copy, or from any part of 0356 it. (Additional permissions may be written to require their own 0357 removal in certain cases when you modify the work.) You may place 0358 additional permissions on material, added by you to a covered work, 0359 for which you have or can give appropriate copyright permission. 0360 0361 Notwithstanding any other provision of this License, for material you 0362 add to a covered work, you may (if authorized by the copyright holders of 0363 that material) supplement the terms of this License with terms: 0364 0365 a) Disclaiming warranty or limiting liability differently from the 0366 terms of sections 15 and 16 of this License; or 0367 0368 b) Requiring preservation of specified reasonable legal notices or 0369 author attributions in that material or in the Appropriate Legal 0370 Notices displayed by works containing it; or 0371 0372 c) Prohibiting misrepresentation of the origin of that material, or 0373 requiring that modified versions of such material be marked in 0374 reasonable ways as different from the original version; or 0375 0376 d) Limiting the use for publicity purposes of names of licensors or 0377 authors of the material; or 0378 0379 e) Declining to grant rights under trademark law for use of some 0380 trade names, trademarks, or service marks; or 0381 0382 f) Requiring indemnification of licensors and authors of that 0383 material by anyone who conveys the material (or modified versions of 0384 it) with contractual assumptions of liability to the recipient, for 0385 any liability that these contractual assumptions directly impose on 0386 those licensors and authors. 0387 0388 All other non-permissive additional terms are considered "further 0389 restrictions" within the meaning of section 10. If the Program as you 0390 received it, or any part of it, contains a notice stating that it is 0391 governed by this License along with a term that is a further 0392 restriction, you may remove that term. If a license document contains 0393 a further restriction but permits relicensing or conveying under this 0394 License, you may add to a covered work material governed by the terms 0395 of that license document, provided that the further restriction does 0396 not survive such relicensing or conveying. 0397 0398 If you add terms to a covered work in accord with this section, you 0399 must place, in the relevant source files, a statement of the 0400 additional terms that apply to those files, or a notice indicating 0401 where to find the applicable terms. 0402 0403 Additional terms, permissive or non-permissive, may be stated in the 0404 form of a separately written license, or stated as exceptions; 0405 the above requirements apply either way. 0406 0407 8. Termination. 0408 0409 You may not propagate or modify a covered work except as expressly 0410 provided under this License. Any attempt otherwise to propagate or 0411 modify it is void, and will automatically terminate your rights under 0412 this License (including any patent licenses granted under the third 0413 paragraph of section 11). 0414 0415 However, if you cease all violation of this License, then your 0416 license from a particular copyright holder is reinstated (a) 0417 provisionally, unless and until the copyright holder explicitly and 0418 finally terminates your license, and (b) permanently, if the copyright 0419 holder fails to notify you of the violation by some reasonable means 0420 prior to 60 days after the cessation. 0421 0422 Moreover, your license from a particular copyright holder is 0423 reinstated permanently if the copyright holder notifies you of the 0424 violation by some reasonable means, this is the first time you have 0425 received notice of violation of this License (for any work) from that 0426 copyright holder, and you cure the violation prior to 30 days after 0427 your receipt of the notice. 0428 0429 Termination of your rights under this section does not terminate the 0430 licenses of parties who have received copies or rights from you under 0431 this License. If your rights have been terminated and not permanently 0432 reinstated, you do not qualify to receive new licenses for the same 0433 material under section 10. 0434 0435 9. Acceptance Not Required for Having Copies. 0436 0437 You are not required to accept this License in order to receive or 0438 run a copy of the Program. Ancillary propagation of a covered work 0439 occurring solely as a consequence of using peer-to-peer transmission 0440 to receive a copy likewise does not require acceptance. However, 0441 nothing other than this License grants you permission to propagate or 0442 modify any covered work. These actions infringe copyright if you do 0443 not accept this License. Therefore, by modifying or propagating a 0444 covered work, you indicate your acceptance of this License to do so. 0445 0446 10. Automatic Licensing of Downstream Recipients. 0447 0448 Each time you convey a covered work, the recipient automatically 0449 receives a license from the original licensors, to run, modify and 0450 propagate that work, subject to this License. You are not responsible 0451 for enforcing compliance by third parties with this License. 0452 0453 An "entity transaction" is a transaction transferring control of an 0454 organization, or substantially all assets of one, or subdividing an 0455 organization, or merging organizations. If propagation of a covered 0456 work results from an entity transaction, each party to that 0457 transaction who receives a copy of the work also receives whatever 0458 licenses to the work the party's predecessor in interest had or could 0459 give under the previous paragraph, plus a right to possession of the 0460 Corresponding Source of the work from the predecessor in interest, if 0461 the predecessor has it or can get it with reasonable efforts. 0462 0463 You may not impose any further restrictions on the exercise of the 0464 rights granted or affirmed under this License. For example, you may 0465 not impose a license fee, royalty, or other charge for exercise of 0466 rights granted under this License, and you may not initiate litigation 0467 (including a cross-claim or counterclaim in a lawsuit) alleging that 0468 any patent claim is infringed by making, using, selling, offering for 0469 sale, or importing the Program or any portion of it. 0470 0471 11. Patents. 0472 0473 A "contributor" is a copyright holder who authorizes use under this 0474 License of the Program or a work on which the Program is based. The 0475 work thus licensed is called the contributor's "contributor version". 0476 0477 A contributor's "essential patent claims" are all patent claims 0478 owned or controlled by the contributor, whether already acquired or 0479 hereafter acquired, that would be infringed by some manner, permitted 0480 by this License, of making, using, or selling its contributor version, 0481 but do not include claims that would be infringed only as a 0482 consequence of further modification of the contributor version. For 0483 purposes of this definition, "control" includes the right to grant 0484 patent sublicenses in a manner consistent with the requirements of 0485 this License. 0486 0487 Each contributor grants you a non-exclusive, worldwide, royalty-free 0488 patent license under the contributor's essential patent claims, to 0489 make, use, sell, offer for sale, import and otherwise run, modify and 0490 propagate the contents of its contributor version. 0491 0492 In the following three paragraphs, a "patent license" is any express 0493 agreement or commitment, however denominated, not to enforce a patent 0494 (such as an express permission to practice a patent or covenant not to 0495 sue for patent infringement). To "grant" such a patent license to a 0496 party means to make such an agreement or commitment not to enforce a 0497 patent against the party. 0498 0499 If you convey a covered work, knowingly relying on a patent license, 0500 and the Corresponding Source of the work is not available for anyone 0501 to copy, free of charge and under the terms of this License, through a 0502 publicly available network server or other readily accessible means, 0503 then you must either (1) cause the Corresponding Source to be so 0504 available, or (2) arrange to deprive yourself of the benefit of the 0505 patent license for this particular work, or (3) arrange, in a manner 0506 consistent with the requirements of this License, to extend the patent 0507 license to downstream recipients. "Knowingly relying" means you have 0508 actual knowledge that, but for the patent license, your conveying the 0509 covered work in a country, or your recipient's use of the covered work 0510 in a country, would infringe one or more identifiable patents in that 0511 country that you have reason to believe are valid. 0512 0513 If, pursuant to or in connection with a single transaction or 0514 arrangement, you convey, or propagate by procuring conveyance of, a 0515 covered work, and grant a patent license to some of the parties 0516 receiving the covered work authorizing them to use, propagate, modify 0517 or convey a specific copy of the covered work, then the patent license 0518 you grant is automatically extended to all recipients of the covered 0519 work and works based on it. 0520 0521 A patent license is "discriminatory" if it does not include within 0522 the scope of its coverage, prohibits the exercise of, or is 0523 conditioned on the non-exercise of one or more of the rights that are 0524 specifically granted under this License. You may not convey a covered 0525 work if you are a party to an arrangement with a third party that is 0526 in the business of distributing software, under which you make payment 0527 to the third party based on the extent of your activity of conveying 0528 the work, and under which the third party grants, to any of the 0529 parties who would receive the covered work from you, a discriminatory 0530 patent license (a) in connection with copies of the covered work 0531 conveyed by you (or copies made from those copies), or (b) primarily 0532 for and in connection with specific products or compilations that 0533 contain the covered work, unless you entered into that arrangement, 0534 or that patent license was granted, prior to 28 March 2007. 0535 0536 Nothing in this License shall be construed as excluding or limiting 0537 any implied license or other defenses to infringement that may 0538 otherwise be available to you under applicable patent law. 0539 0540 12. No Surrender of Others' Freedom. 0541 0542 If conditions are imposed on you (whether by court order, agreement or 0543 otherwise) that contradict the conditions of this License, they do not 0544 excuse you from the conditions of this License. If you cannot convey a 0545 covered work so as to satisfy simultaneously your obligations under this 0546 License and any other pertinent obligations, then as a consequence you may 0547 not convey it at all. For example, if you agree to terms that obligate you 0548 to collect a royalty for further conveying from those to whom you convey 0549 the Program, the only way you could satisfy both those terms and this 0550 License would be to refrain entirely from conveying the Program. 0551 0552 13. Use with the GNU Affero General Public License. 0553 0554 Notwithstanding any other provision of this License, you have 0555 permission to link or combine any covered work with a work licensed 0556 under version 3 of the GNU Affero General Public License into a single 0557 combined work, and to convey the resulting work. The terms of this 0558 License will continue to apply to the part which is the covered work, 0559 but the special requirements of the GNU Affero General Public License, 0560 section 13, concerning interaction through a network will apply to the 0561 combination as such. 0562 0563 14. Revised Versions of this License. 0564 0565 The Free Software Foundation may publish revised and/or new versions of 0566 the GNU General Public License from time to time. Such new versions will 0567 be similar in spirit to the present version, but may differ in detail to 0568 address new problems or concerns. 0569 0570 Each version is given a distinguishing version number. If the 0571 Program specifies that a certain numbered version of the GNU General 0572 Public License "or any later version" applies to it, you have the 0573 option of following the terms and conditions either of that numbered 0574 version or of any later version published by the Free Software 0575 Foundation. If the Program does not specify a version number of the 0576 GNU General Public License, you may choose any version ever published 0577 by the Free Software Foundation. 0578 0579 If the Program specifies that a proxy can decide which future 0580 versions of the GNU General Public License can be used, that proxy's 0581 public statement of acceptance of a version permanently authorizes you 0582 to choose that version for the Program. 0583 0584 Later license versions may give you additional or different 0585 permissions. However, no additional obligations are imposed on any 0586 author or copyright holder as a result of your choosing to follow a 0587 later version. 0588 0589 15. Disclaimer of Warranty. 0590 0591 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 0592 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 0593 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 0594 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 0595 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 0596 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 0597 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 0598 ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 0599 0600 16. Limitation of Liability. 0601 0602 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 0603 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 0604 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 0605 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 0606 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 0607 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 0608 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 0609 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 0610 SUCH DAMAGES. 0611 0612 17. Interpretation of Sections 15 and 16. 0613 0614 If the disclaimer of warranty and limitation of liability provided 0615 above cannot be given local legal effect according to their terms, 0616 reviewing courts shall apply local law that most closely approximates 0617 an absolute waiver of all civil liability in connection with the 0618 Program, unless a warranty or assumption of liability accompanies a 0619 copy of the Program in return for a fee. 0620 0621 END OF TERMS AND CONDITIONS 0622 0623 How to Apply These Terms to Your New Programs 0624 0625 If you develop a new program, and you want it to be of the greatest 0626 possible use to the public, the best way to achieve this is to make it 0627 free software which everyone can redistribute and change under these terms. 0628 0629 To do so, attach the following notices to the program. It is safest 0630 to attach them to the start of each source file to most effectively 0631 state the exclusion of warranty; and each file should have at least 0632 the "copyright" line and a pointer to where the full notice is found. 0633 0634 <one line to give the program's name and a brief idea of what it does.> 0635 Copyright (C) <year> <name of author> 0636 0637 This program is free software: you can redistribute it and/or modify 0638 it under the terms of the GNU General Public License as published by 0639 the Free Software Foundation, either version 3 of the License, or 0640 (at your option) any later version. 0641 0642 This program is distributed in the hope that it will be useful, 0643 but WITHOUT ANY WARRANTY; without even the implied warranty of 0644 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 0645 GNU General Public License for more details. 0646 0647 You should have received a copy of the GNU General Public License 0648 along with this program. If not, see <https://www.gnu.org/licenses/>. 0649 0650 Also add information on how to contact you by electronic and paper mail. 0651 0652 If the program does terminal interaction, make it output a short 0653 notice like this when it starts in an interactive mode: 0654 0655 <program> Copyright (C) <year> <name of author> 0656 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 0657 This is free software, and you are welcome to redistribute it 0658 under certain conditions; type `show c' for details. 0659 0660 The hypothetical commands `show w' and `show c' should show the appropriate 0661 parts of the General Public License. Of course, your program's commands 0662 might be different; for a GUI interface, you would use an "about box". 0663 0664 You should also get your employer (if you work as a programmer) or school, 0665 if any, to sign a "copyright disclaimer" for the program, if necessary. 0666 For more information on this, and how to apply and follow the GNU GPL, see 0667 <https://www.gnu.org/licenses/>. 0668 0669 The GNU General Public License does not permit incorporating your program 0670 into proprietary programs. If your program is a subroutine library, you 0671 may consider it more useful to permit linking proprietary applications with 0672 the library. If this is what you want to do, use the GNU Lesser General 0673 Public License instead of this License. But first, please read 0674 <https://www.gnu.org/licenses/why-not-lgpl.html>.
