0001 GNU AFFERO GENERAL PUBLIC LICENSE 0002 Version 3, 19 November 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 Affero General Public License is a free, copyleft license for 0011 software and other kinds of works, specifically designed to ensure 0012 cooperation with the community in the case of network server software. 0013 0014 The licenses for most software and other practical works are designed 0015 to take away your freedom to share and change the works. By contrast, 0016 our General Public Licenses are intended to guarantee your freedom to 0017 share and change all versions of a program--to make sure it remains free 0018 software for all its users. 0019 0020 When we speak of free software, we are referring to freedom, not 0021 price. Our General Public Licenses are designed to make sure that you 0022 have the freedom to distribute copies of free software (and charge for 0023 them if you wish), that you receive source code or can get it if you 0024 want it, that you can change the software or use pieces of it in new 0025 free programs, and that you know you can do these things. 0026 0027 Developers that use our General Public Licenses protect your rights 0028 with two steps: (1) assert copyright on the software, and (2) offer 0029 you this License which gives you legal permission to copy, distribute 0030 and/or modify the software. 0031 0032 A secondary benefit of defending all users' freedom is that 0033 improvements made in alternate versions of the program, if they 0034 receive widespread use, become available for other developers to 0035 incorporate. Many developers of free software are heartened and 0036 encouraged by the resulting cooperation. However, in the case of 0037 software used on network servers, this result may fail to come about. 0038 The GNU General Public License permits making a modified version and 0039 letting the public access it on a server without ever releasing its 0040 source code to the public. 0041 0042 The GNU Affero General Public License is designed specifically to 0043 ensure that, in such cases, the modified source code becomes available 0044 to the community. It requires the operator of a network server to 0045 provide the source code of the modified version running there to the 0046 users of that server. Therefore, public use of a modified version, on 0047 a publicly accessible server, gives the public access to the source 0048 code of the modified version. 0049 0050 An older license, called the Affero General Public License and 0051 published by Affero, was designed to accomplish similar goals. This is 0052 a different license, not a version of the Affero GPL, but Affero has 0053 released a new version of the Affero GPL which permits relicensing under 0054 this license. 0055 0056 The precise terms and conditions for copying, distribution and 0057 modification follow. 0058 0059 TERMS AND CONDITIONS 0060 0061 0. Definitions. 0062 0063 "This License" refers to version 3 of the GNU Affero General Public License. 0064 0065 "Copyright" also means copyright-like laws that apply to other kinds of 0066 works, such as semiconductor masks. 0067 0068 "The Program" refers to any copyrightable work licensed under this 0069 License. Each licensee is addressed as "you". "Licensees" and 0070 "recipients" may be individuals or organizations. 0071 0072 To "modify" a work means to copy from or adapt all or part of the work 0073 in a fashion requiring copyright permission, other than the making of an 0074 exact copy. The resulting work is called a "modified version" of the 0075 earlier work or a work "based on" the earlier work. 0076 0077 A "covered work" means either the unmodified Program or a work based 0078 on the Program. 0079 0080 To "propagate" a work means to do anything with it that, without 0081 permission, would make you directly or secondarily liable for 0082 infringement under applicable copyright law, except executing it on a 0083 computer or modifying a private copy. Propagation includes copying, 0084 distribution (with or without modification), making available to the 0085 public, and in some countries other activities as well. 0086 0087 To "convey" a work means any kind of propagation that enables other 0088 parties to make or receive copies. Mere interaction with a user through 0089 a computer network, with no transfer of a copy, is not conveying. 0090 0091 An interactive user interface displays "Appropriate Legal Notices" 0092 to the extent that it includes a convenient and prominently visible 0093 feature that (1) displays an appropriate copyright notice, and (2) 0094 tells the user that there is no warranty for the work (except to the 0095 extent that warranties are provided), that licensees may convey the 0096 work under this License, and how to view a copy of this License. If 0097 the interface presents a list of user commands or options, such as a 0098 menu, a prominent item in the list meets this criterion. 0099 0100 1. Source Code. 0101 0102 The "source code" for a work means the preferred form of the work 0103 for making modifications to it. "Object code" means any non-source 0104 form of a work. 0105 0106 A "Standard Interface" means an interface that either is an official 0107 standard defined by a recognized standards body, or, in the case of 0108 interfaces specified for a particular programming language, one that 0109 is widely used among developers working in that language. 0110 0111 The "System Libraries" of an executable work include anything, other 0112 than the work as a whole, that (a) is included in the normal form of 0113 packaging a Major Component, but which is not part of that Major 0114 Component, and (b) serves only to enable use of the work with that 0115 Major Component, or to implement a Standard Interface for which an 0116 implementation is available to the public in source code form. A 0117 "Major Component", in this context, means a major essential component 0118 (kernel, window system, and so on) of the specific operating system 0119 (if any) on which the executable work runs, or a compiler used to 0120 produce the work, or an object code interpreter used to run it. 0121 0122 The "Corresponding Source" for a work in object code form means all 0123 the source code needed to generate, install, and (for an executable 0124 work) run the object code and to modify the work, including scripts to 0125 control those activities. However, it does not include the work's 0126 System Libraries, or general-purpose tools or generally available free 0127 programs which are used unmodified in performing those activities but 0128 which are not part of the work. For example, Corresponding Source 0129 includes interface definition files associated with source files for 0130 the work, and the source code for shared libraries and dynamically 0131 linked subprograms that the work is specifically designed to require, 0132 such as by intimate data communication or control flow between those 0133 subprograms and other parts of the work. 0134 0135 The Corresponding Source need not include anything that users 0136 can regenerate automatically from other parts of the Corresponding 0137 Source. 0138 0139 The Corresponding Source for a work in source code form is that 0140 same work. 0141 0142 2. Basic Permissions. 0143 0144 All rights granted under this License are granted for the term of 0145 copyright on the Program, and are irrevocable provided the stated 0146 conditions are met. This License explicitly affirms your unlimited 0147 permission to run the unmodified Program. The output from running a 0148 covered work is covered by this License only if the output, given its 0149 content, constitutes a covered work. This License acknowledges your 0150 rights of fair use or other equivalent, as provided by copyright law. 0151 0152 You may make, run and propagate covered works that you do not 0153 convey, without conditions so long as your license otherwise remains 0154 in force. You may convey covered works to others for the sole purpose 0155 of having them make modifications exclusively for you, or provide you 0156 with facilities for running those works, provided that you comply with 0157 the terms of this License in conveying all material for which you do 0158 not control copyright. Those thus making or running the covered works 0159 for you must do so exclusively on your behalf, under your direction 0160 and control, on terms that prohibit them from making any copies of 0161 your copyrighted material outside their relationship with you. 0162 0163 Conveying under any other circumstances is permitted solely under 0164 the conditions stated below. Sublicensing is not allowed; section 10 0165 makes it unnecessary. 0166 0167 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 0168 0169 No covered work shall be deemed part of an effective technological 0170 measure under any applicable law fulfilling obligations under article 0171 11 of the WIPO copyright treaty adopted on 20 December 1996, or 0172 similar laws prohibiting or restricting circumvention of such 0173 measures. 0174 0175 When you convey a covered work, you waive any legal power to forbid 0176 circumvention of technological measures to the extent such circumvention 0177 is effected by exercising rights under this License with respect to 0178 the covered work, and you disclaim any intention to limit operation or 0179 modification of the work as a means of enforcing, against the work's 0180 users, your or third parties' legal rights to forbid circumvention of 0181 technological measures. 0182 0183 4. Conveying Verbatim Copies. 0184 0185 You may convey verbatim copies of the Program's source code as you 0186 receive it, in any medium, provided that you conspicuously and 0187 appropriately publish on each copy an appropriate copyright notice; 0188 keep intact all notices stating that this License and any 0189 non-permissive terms added in accord with section 7 apply to the code; 0190 keep intact all notices of the absence of any warranty; and give all 0191 recipients a copy of this License along with the Program. 0192 0193 You may charge any price or no price for each copy that you convey, 0194 and you may offer support or warranty protection for a fee. 0195 0196 5. Conveying Modified Source Versions. 0197 0198 You may convey a work based on the Program, or the modifications to 0199 produce it from the Program, in the form of source code under the 0200 terms of section 4, provided that you also meet all of these conditions: 0201 0202 a) The work must carry prominent notices stating that you modified 0203 it, and giving a relevant date. 0204 0205 b) The work must carry prominent notices stating that it is 0206 released under this License and any conditions added under section 0207 7. This requirement modifies the requirement in section 4 to 0208 "keep intact all notices". 0209 0210 c) You must license the entire work, as a whole, under this 0211 License to anyone who comes into possession of a copy. This 0212 License will therefore apply, along with any applicable section 7 0213 additional terms, to the whole of the work, and all its parts, 0214 regardless of how they are packaged. This License gives no 0215 permission to license the work in any other way, but it does not 0216 invalidate such permission if you have separately received it. 0217 0218 d) If the work has interactive user interfaces, each must display 0219 Appropriate Legal Notices; however, if the Program has interactive 0220 interfaces that do not display Appropriate Legal Notices, your 0221 work need not make them do so. 0222 0223 A compilation of a covered work with other separate and independent 0224 works, which are not by their nature extensions of the covered work, 0225 and which are not combined with it such as to form a larger program, 0226 in or on a volume of a storage or distribution medium, is called an 0227 "aggregate" if the compilation and its resulting copyright are not 0228 used to limit the access or legal rights of the compilation's users 0229 beyond what the individual works permit. Inclusion of a covered work 0230 in an aggregate does not cause this License to apply to the other 0231 parts of the aggregate. 0232 0233 6. Conveying Non-Source Forms. 0234 0235 You may convey a covered work in object code form under the terms 0236 of sections 4 and 5, provided that you also convey the 0237 machine-readable Corresponding Source under the terms of this License, 0238 in one of these ways: 0239 0240 a) Convey the object code in, or embodied in, a physical product 0241 (including a physical distribution medium), accompanied by the 0242 Corresponding Source fixed on a durable physical medium 0243 customarily used for software interchange. 0244 0245 b) Convey the object code in, or embodied in, a physical product 0246 (including a physical distribution medium), accompanied by a 0247 written offer, valid for at least three years and valid for as 0248 long as you offer spare parts or customer support for that product 0249 model, to give anyone who possesses the object code either (1) a 0250 copy of the Corresponding Source for all the software in the 0251 product that is covered by this License, on a durable physical 0252 medium customarily used for software interchange, for a price no 0253 more than your reasonable cost of physically performing this 0254 conveying of source, or (2) access to copy the 0255 Corresponding Source from a network server at no charge. 0256 0257 c) Convey individual copies of the object code with a copy of the 0258 written offer to provide the Corresponding Source. This 0259 alternative is allowed only occasionally and noncommercially, and 0260 only if you received the object code with such an offer, in accord 0261 with subsection 6b. 0262 0263 d) Convey the object code by offering access from a designated 0264 place (gratis or for a charge), and offer equivalent access to the 0265 Corresponding Source in the same way through the same place at no 0266 further charge. You need not require recipients to copy the 0267 Corresponding Source along with the object code. If the place to 0268 copy the object code is a network server, the Corresponding Source 0269 may be on a different server (operated by you or a third party) 0270 that supports equivalent copying facilities, provided you maintain 0271 clear directions next to the object code saying where to find the 0272 Corresponding Source. Regardless of what server hosts the 0273 Corresponding Source, you remain obligated to ensure that it is 0274 available for as long as needed to satisfy these requirements. 0275 0276 e) Convey the object code using peer-to-peer transmission, provided 0277 you inform other peers where the object code and Corresponding 0278 Source of the work are being offered to the general public at no 0279 charge under subsection 6d. 0280 0281 A separable portion of the object code, whose source code is excluded 0282 from the Corresponding Source as a System Library, need not be 0283 included in conveying the object code work. 0284 0285 A "User Product" is either (1) a "consumer product", which means any 0286 tangible personal property which is normally used for personal, family, 0287 or household purposes, or (2) anything designed or sold for incorporation 0288 into a dwelling. In determining whether a product is a consumer product, 0289 doubtful cases shall be resolved in favor of coverage. For a particular 0290 product received by a particular user, "normally used" refers to a 0291 typical or common use of that class of product, regardless of the status 0292 of the particular user or of the way in which the particular user 0293 actually uses, or expects or is expected to use, the product. A product 0294 is a consumer product regardless of whether the product has substantial 0295 commercial, industrial or non-consumer uses, unless such uses represent 0296 the only significant mode of use of the product. 0297 0298 "Installation Information" for a User Product means any methods, 0299 procedures, authorization keys, or other information required to install 0300 and execute modified versions of a covered work in that User Product from 0301 a modified version of its Corresponding Source. The information must 0302 suffice to ensure that the continued functioning of the modified object 0303 code is in no case prevented or interfered with solely because 0304 modification has been made. 0305 0306 If you convey an object code work under this section in, or with, or 0307 specifically for use in, a User Product, and the conveying occurs as 0308 part of a transaction in which the right of possession and use of the 0309 User Product is transferred to the recipient in perpetuity or for a 0310 fixed term (regardless of how the transaction is characterized), the 0311 Corresponding Source conveyed under this section must be accompanied 0312 by the Installation Information. But this requirement does not apply 0313 if neither you nor any third party retains the ability to install 0314 modified object code on the User Product (for example, the work has 0315 been installed in ROM). 0316 0317 The requirement to provide Installation Information does not include a 0318 requirement to continue to provide support service, warranty, or updates 0319 for a work that has been modified or installed by the recipient, or for 0320 the User Product in which it has been modified or installed. Access to a 0321 network may be denied when the modification itself materially and 0322 adversely affects the operation of the network or violates the rules and 0323 protocols for communication across the network. 0324 0325 Corresponding Source conveyed, and Installation Information provided, 0326 in accord with this section must be in a format that is publicly 0327 documented (and with an implementation available to the public in 0328 source code form), and must require no special password or key for 0329 unpacking, reading or copying. 0330 0331 7. Additional Terms. 0332 0333 "Additional permissions" are terms that supplement the terms of this 0334 License by making exceptions from one or more of its conditions. 0335 Additional permissions that are applicable to the entire Program shall 0336 be treated as though they were included in this License, to the extent 0337 that they are valid under applicable law. If additional permissions 0338 apply only to part of the Program, that part may be used separately 0339 under those permissions, but the entire Program remains governed by 0340 this License without regard to the additional permissions. 0341 0342 When you convey a copy of a covered work, you may at your option 0343 remove any additional permissions from that copy, or from any part of 0344 it. (Additional permissions may be written to require their own 0345 removal in certain cases when you modify the work.) You may place 0346 additional permissions on material, added by you to a covered work, 0347 for which you have or can give appropriate copyright permission. 0348 0349 Notwithstanding any other provision of this License, for material you 0350 add to a covered work, you may (if authorized by the copyright holders of 0351 that material) supplement the terms of this License with terms: 0352 0353 a) Disclaiming warranty or limiting liability differently from the 0354 terms of sections 15 and 16 of this License; or 0355 0356 b) Requiring preservation of specified reasonable legal notices or 0357 author attributions in that material or in the Appropriate Legal 0358 Notices displayed by works containing it; or 0359 0360 c) Prohibiting misrepresentation of the origin of that material, or 0361 requiring that modified versions of such material be marked in 0362 reasonable ways as different from the original version; or 0363 0364 d) Limiting the use for publicity purposes of names of licensors or 0365 authors of the material; or 0366 0367 e) Declining to grant rights under trademark law for use of some 0368 trade names, trademarks, or service marks; or 0369 0370 f) Requiring indemnification of licensors and authors of that 0371 material by anyone who conveys the material (or modified versions of 0372 it) with contractual assumptions of liability to the recipient, for 0373 any liability that these contractual assumptions directly impose on 0374 those licensors and authors. 0375 0376 All other non-permissive additional terms are considered "further 0377 restrictions" within the meaning of section 10. If the Program as you 0378 received it, or any part of it, contains a notice stating that it is 0379 governed by this License along with a term that is a further 0380 restriction, you may remove that term. If a license document contains 0381 a further restriction but permits relicensing or conveying under this 0382 License, you may add to a covered work material governed by the terms 0383 of that license document, provided that the further restriction does 0384 not survive such relicensing or conveying. 0385 0386 If you add terms to a covered work in accord with this section, you 0387 must place, in the relevant source files, a statement of the 0388 additional terms that apply to those files, or a notice indicating 0389 where to find the applicable terms. 0390 0391 Additional terms, permissive or non-permissive, may be stated in the 0392 form of a separately written license, or stated as exceptions; 0393 the above requirements apply either way. 0394 0395 8. Termination. 0396 0397 You may not propagate or modify a covered work except as expressly 0398 provided under this License. Any attempt otherwise to propagate or 0399 modify it is void, and will automatically terminate your rights under 0400 this License (including any patent licenses granted under the third 0401 paragraph of section 11). 0402 0403 However, if you cease all violation of this License, then your 0404 license from a particular copyright holder is reinstated (a) 0405 provisionally, unless and until the copyright holder explicitly and 0406 finally terminates your license, and (b) permanently, if the copyright 0407 holder fails to notify you of the violation by some reasonable means 0408 prior to 60 days after the cessation. 0409 0410 Moreover, your license from a particular copyright holder is 0411 reinstated permanently if the copyright holder notifies you of the 0412 violation by some reasonable means, this is the first time you have 0413 received notice of violation of this License (for any work) from that 0414 copyright holder, and you cure the violation prior to 30 days after 0415 your receipt of the notice. 0416 0417 Termination of your rights under this section does not terminate the 0418 licenses of parties who have received copies or rights from you under 0419 this License. If your rights have been terminated and not permanently 0420 reinstated, you do not qualify to receive new licenses for the same 0421 material under section 10. 0422 0423 9. Acceptance Not Required for Having Copies. 0424 0425 You are not required to accept this License in order to receive or 0426 run a copy of the Program. Ancillary propagation of a covered work 0427 occurring solely as a consequence of using peer-to-peer transmission 0428 to receive a copy likewise does not require acceptance. However, 0429 nothing other than this License grants you permission to propagate or 0430 modify any covered work. These actions infringe copyright if you do 0431 not accept this License. Therefore, by modifying or propagating a 0432 covered work, you indicate your acceptance of this License to do so. 0433 0434 10. Automatic Licensing of Downstream Recipients. 0435 0436 Each time you convey a covered work, the recipient automatically 0437 receives a license from the original licensors, to run, modify and 0438 propagate that work, subject to this License. You are not responsible 0439 for enforcing compliance by third parties with this License. 0440 0441 An "entity transaction" is a transaction transferring control of an 0442 organization, or substantially all assets of one, or subdividing an 0443 organization, or merging organizations. If propagation of a covered 0444 work results from an entity transaction, each party to that 0445 transaction who receives a copy of the work also receives whatever 0446 licenses to the work the party's predecessor in interest had or could 0447 give under the previous paragraph, plus a right to possession of the 0448 Corresponding Source of the work from the predecessor in interest, if 0449 the predecessor has it or can get it with reasonable efforts. 0450 0451 You may not impose any further restrictions on the exercise of the 0452 rights granted or affirmed under this License. For example, you may 0453 not impose a license fee, royalty, or other charge for exercise of 0454 rights granted under this License, and you may not initiate litigation 0455 (including a cross-claim or counterclaim in a lawsuit) alleging that 0456 any patent claim is infringed by making, using, selling, offering for 0457 sale, or importing the Program or any portion of it. 0458 0459 11. Patents. 0460 0461 A "contributor" is a copyright holder who authorizes use under this 0462 License of the Program or a work on which the Program is based. The 0463 work thus licensed is called the contributor's "contributor version". 0464 0465 A contributor's "essential patent claims" are all patent claims 0466 owned or controlled by the contributor, whether already acquired or 0467 hereafter acquired, that would be infringed by some manner, permitted 0468 by this License, of making, using, or selling its contributor version, 0469 but do not include claims that would be infringed only as a 0470 consequence of further modification of the contributor version. For 0471 purposes of this definition, "control" includes the right to grant 0472 patent sublicenses in a manner consistent with the requirements of 0473 this License. 0474 0475 Each contributor grants you a non-exclusive, worldwide, royalty-free 0476 patent license under the contributor's essential patent claims, to 0477 make, use, sell, offer for sale, import and otherwise run, modify and 0478 propagate the contents of its contributor version. 0479 0480 In the following three paragraphs, a "patent license" is any express 0481 agreement or commitment, however denominated, not to enforce a patent 0482 (such as an express permission to practice a patent or covenant not to 0483 sue for patent infringement). To "grant" such a patent license to a 0484 party means to make such an agreement or commitment not to enforce a 0485 patent against the party. 0486 0487 If you convey a covered work, knowingly relying on a patent license, 0488 and the Corresponding Source of the work is not available for anyone 0489 to copy, free of charge and under the terms of this License, through a 0490 publicly available network server or other readily accessible means, 0491 then you must either (1) cause the Corresponding Source to be so 0492 available, or (2) arrange to deprive yourself of the benefit of the 0493 patent license for this particular work, or (3) arrange, in a manner 0494 consistent with the requirements of this License, to extend the patent 0495 license to downstream recipients. "Knowingly relying" means you have 0496 actual knowledge that, but for the patent license, your conveying the 0497 covered work in a country, or your recipient's use of the covered work 0498 in a country, would infringe one or more identifiable patents in that 0499 country that you have reason to believe are valid. 0500 0501 If, pursuant to or in connection with a single transaction or 0502 arrangement, you convey, or propagate by procuring conveyance of, a 0503 covered work, and grant a patent license to some of the parties 0504 receiving the covered work authorizing them to use, propagate, modify 0505 or convey a specific copy of the covered work, then the patent license 0506 you grant is automatically extended to all recipients of the covered 0507 work and works based on it. 0508 0509 A patent license is "discriminatory" if it does not include within 0510 the scope of its coverage, prohibits the exercise of, or is 0511 conditioned on the non-exercise of one or more of the rights that are 0512 specifically granted under this License. You may not convey a covered 0513 work if you are a party to an arrangement with a third party that is 0514 in the business of distributing software, under which you make payment 0515 to the third party based on the extent of your activity of conveying 0516 the work, and under which the third party grants, to any of the 0517 parties who would receive the covered work from you, a discriminatory 0518 patent license (a) in connection with copies of the covered work 0519 conveyed by you (or copies made from those copies), or (b) primarily 0520 for and in connection with specific products or compilations that 0521 contain the covered work, unless you entered into that arrangement, 0522 or that patent license was granted, prior to 28 March 2007. 0523 0524 Nothing in this License shall be construed as excluding or limiting 0525 any implied license or other defenses to infringement that may 0526 otherwise be available to you under applicable patent law. 0527 0528 12. No Surrender of Others' Freedom. 0529 0530 If conditions are imposed on you (whether by court order, agreement or 0531 otherwise) that contradict the conditions of this License, they do not 0532 excuse you from the conditions of this License. If you cannot convey a 0533 covered work so as to satisfy simultaneously your obligations under this 0534 License and any other pertinent obligations, then as a consequence you may 0535 not convey it at all. For example, if you agree to terms that obligate you 0536 to collect a royalty for further conveying from those to whom you convey 0537 the Program, the only way you could satisfy both those terms and this 0538 License would be to refrain entirely from conveying the Program. 0539 0540 13. Remote Network Interaction; Use with the GNU General Public License. 0541 0542 Notwithstanding any other provision of this License, if you modify the 0543 Program, your modified version must prominently offer all users 0544 interacting with it remotely through a computer network (if your version 0545 supports such interaction) an opportunity to receive the Corresponding 0546 Source of your version by providing access to the Corresponding Source 0547 from a network server at no charge, through some standard or customary 0548 means of facilitating copying of software. This Corresponding Source 0549 shall include the Corresponding Source for any work covered by version 3 0550 of the GNU General Public License that is incorporated pursuant to the 0551 following paragraph. 0552 0553 Notwithstanding any other provision of this License, you have 0554 permission to link or combine any covered work with a work licensed 0555 under version 3 of the GNU General Public License into a single 0556 combined work, and to convey the resulting work. The terms of this 0557 License will continue to apply to the part which is the covered work, 0558 but the work with which it is combined will remain governed by version 0559 3 of the GNU General Public License. 0560 0561 14. Revised Versions of this License. 0562 0563 The Free Software Foundation may publish revised and/or new versions of 0564 the GNU Affero General Public License from time to time. Such new versions 0565 will be similar in spirit to the present version, but may differ in detail to 0566 address new problems or concerns. 0567 0568 Each version is given a distinguishing version number. If the 0569 Program specifies that a certain numbered version of the GNU Affero General 0570 Public License "or any later version" applies to it, you have the 0571 option of following the terms and conditions either of that numbered 0572 version or of any later version published by the Free Software 0573 Foundation. If the Program does not specify a version number of the 0574 GNU Affero General Public License, you may choose any version ever published 0575 by the Free Software Foundation. 0576 0577 If the Program specifies that a proxy can decide which future 0578 versions of the GNU Affero General Public License can be used, that proxy's 0579 public statement of acceptance of a version permanently authorizes you 0580 to choose that version for the Program. 0581 0582 Later license versions may give you additional or different 0583 permissions. However, no additional obligations are imposed on any 0584 author or copyright holder as a result of your choosing to follow a 0585 later version. 0586 0587 15. Disclaimer of Warranty. 0588 0589 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 0590 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 0591 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 0592 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 0593 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 0594 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 0595 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 0596 ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 0597 0598 16. Limitation of Liability. 0599 0600 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 0601 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 0602 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 0603 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 0604 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 0605 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 0606 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 0607 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 0608 SUCH DAMAGES. 0609 0610 17. Interpretation of Sections 15 and 16. 0611 0612 If the disclaimer of warranty and limitation of liability provided 0613 above cannot be given local legal effect according to their terms, 0614 reviewing courts shall apply local law that most closely approximates 0615 an absolute waiver of all civil liability in connection with the 0616 Program, unless a warranty or assumption of liability accompanies a 0617 copy of the Program in return for a fee. 0618 0619 END OF TERMS AND CONDITIONS 0620 0621 How to Apply These Terms to Your New Programs 0622 0623 If you develop a new program, and you want it to be of the greatest 0624 possible use to the public, the best way to achieve this is to make it 0625 free software which everyone can redistribute and change under these terms. 0626 0627 To do so, attach the following notices to the program. It is safest 0628 to attach them to the start of each source file to most effectively 0629 state the exclusion of warranty; and each file should have at least 0630 the "copyright" line and a pointer to where the full notice is found. 0631 0632 <one line to give the program's name and a brief idea of what it does.> 0633 Copyright (C) <year> <name of author> 0634 0635 This program is free software: you can redistribute it and/or modify 0636 it under the terms of the GNU Affero General Public License as published by 0637 the Free Software Foundation, either version 3 of the License, or 0638 (at your option) any later version. 0639 0640 This program is distributed in the hope that it will be useful, 0641 but WITHOUT ANY WARRANTY; without even the implied warranty of 0642 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 0643 GNU Affero General Public License for more details. 0644 0645 You should have received a copy of the GNU Affero General Public License 0646 along with this program. If not, see <https://www.gnu.org/licenses/>. 0647 0648 Also add information on how to contact you by electronic and paper mail. 0649 0650 If your software can interact with users remotely through a computer 0651 network, you should also make sure that it provides a way for users to 0652 get its source. For example, if your program is a web application, its 0653 interface could display a "Source" link that leads users to an archive 0654 of the code. There are many ways you could offer source, and different 0655 solutions will be better for different programs; see section 13 for the 0656 specific requirements. 0657 0658 You should also get your employer (if you work as a programmer) or school, 0659 if any, to sign a "copyright disclaimer" for the program, if necessary. 0660 For more information on this, and how to apply and follow the GNU AGPL, see 0661 <https://www.gnu.org/licenses/>.
