0001 GNU AFFERO GENERAL PUBLIC LICENSE 0002 Version 3, 19 November 2007 0003 0004 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 0005 0006 Everyone is permitted to copy and distribute verbatim copies of this license 0007 document, but changing it is not allowed. 0008 0009 Preamble 0010 0011 The GNU Affero General Public License is a free, copyleft license for software 0012 and other kinds of works, specifically designed to ensure cooperation with 0013 the community in the case of network server software. 0014 0015 The licenses for most software and other practical works are designed to take 0016 away your freedom to share and change the works. By contrast, our General 0017 Public Licenses are intended to guarantee your freedom to share and change 0018 all versions of a program--to make sure it remains free software for all its 0019 users. 0020 0021 When we speak of free software, we are referring to freedom, not price. Our 0022 General Public Licenses are designed to make sure that you have the freedom 0023 to distribute copies of free software (and charge for them if you wish), that 0024 you receive source code or can get it if you want it, that you can change 0025 the software or use pieces of it in new free programs, and that you know you 0026 can do these things. 0027 0028 Developers that use our General Public Licenses protect your rights with two 0029 steps: (1) assert copyright on the software, and (2) offer you this License 0030 which gives you legal permission to copy, distribute and/or modify the software. 0031 0032 A secondary benefit of defending all users' freedom is that improvements made 0033 in alternate versions of the program, if they receive widespread use, become 0034 available for other developers to incorporate. Many developers of free software 0035 are heartened and encouraged by the resulting cooperation. However, in the 0036 case of software used on network servers, this result may fail to come about. 0037 The GNU General Public License permits making a modified version and letting 0038 the public access it on a server without ever releasing its source code to 0039 the public. 0040 0041 The GNU Affero General Public License is designed specifically to ensure that, 0042 in such cases, the modified source code becomes available to the community. 0043 It requires the operator of a network server to provide the source code of 0044 the modified version running there to the users of that server. Therefore, 0045 public use of a modified version, on a publicly accessible server, gives the 0046 public access to the source code of the modified version. 0047 0048 An older license, called the Affero General Public License and published by 0049 Affero, was designed to accomplish similar goals. This is a different license, 0050 not a version of the Affero GPL, but Affero has released a new version of 0051 the Affero GPL which permits relicensing under this license. 0052 0053 The precise terms and conditions for copying, distribution and modification 0054 follow. 0055 0056 TERMS AND CONDITIONS 0057 0058 0. Definitions. 0059 0060 "This License" refers to version 3 of the GNU Affero General Public License. 0061 0062 "Copyright" also means copyright-like laws that apply to other kinds of works, 0063 such as semiconductor masks. 0064 0065 "The Program" refers to any copyrightable work licensed under this License. 0066 Each licensee is addressed as "you". "Licensees" and "recipients" may be 0067 individuals or organizations. 0068 0069 To "modify" a work means to copy from or adapt all or part of the work in 0070 a fashion requiring copyright permission, other than the making of an exact 0071 copy. The resulting work is called a "modified version" of the earlier work 0072 or a work "based on" the earlier work. 0073 0074 A "covered work" means either the unmodified Program or a work based on the 0075 Program. 0076 0077 To "propagate" a work means to do anything with it that, without permission, 0078 would make you directly or secondarily liable for infringement under applicable 0079 copyright law, except executing it on a computer or modifying a private copy. 0080 Propagation includes copying, distribution (with or without modification), 0081 making available to the public, and in some countries other activities as 0082 well. 0083 0084 To "convey" a work means any kind of propagation that enables other parties 0085 to make or receive copies. Mere interaction with a user through a computer 0086 network, with no transfer of a copy, is not conveying. 0087 0088 An interactive user interface displays "Appropriate Legal Notices" to the 0089 extent that it includes a convenient and prominently visible feature that 0090 (1) displays an appropriate copyright notice, and (2) tells the user that 0091 there is no warranty for the work (except to the extent that warranties are 0092 provided), that licensees may convey the work under this License, and how 0093 to view a copy of this License. If the interface presents a list of user 0094 commands or options, such as a menu, a prominent item in the list meets this 0095 criterion. 0096 0097 1. Source Code. 0098 The "source code" for a work means the preferred form of the work for making 0099 modifications to it. "Object code" means any non-source form of a work. 0100 0101 A "Standard Interface" means an interface that either is an official standard 0102 defined by a recognized standards body, or, in the case of interfaces specified 0103 for a particular programming language, one that is widely used among developers 0104 working in that language. 0105 0106 The "System Libraries" of an executable work include anything, other than 0107 the work as a whole, that (a) is included in the normal form of packaging 0108 a Major Component, but which is not part of that Major Component, and (b) 0109 serves only to enable use of the work with that Major Component, or to implement 0110 a Standard Interface for which an implementation is available to the public 0111 in source code form. A "Major Component", in this context, means a major 0112 essential component (kernel, window system, and so on) of the specific operating 0113 system (if any) on which the executable work runs, or a compiler used to produce 0114 the work, or an object code interpreter used to run it. 0115 0116 The "Corresponding Source" for a work in object code form means all the source 0117 code needed to generate, install, and (for an executable work) run the object 0118 code and to modify the work, including scripts to control those activities. 0119 However, it does not include the work's System Libraries, or general-purpose 0120 tools or generally available free programs which are used unmodified in performing 0121 those activities but which are not part of the work. For example, Corresponding 0122 Source includes interface definition files associated with source files for 0123 the work, and the source code for shared libraries and dynamically linked 0124 subprograms that the work is specifically designed to require, such as by 0125 intimate data communication or control flow between those 0126 subprograms and other parts of the work. 0127 0128 The Corresponding Source need not include anything that users can regenerate 0129 automatically from other parts of the Corresponding Source. 0130 0131 The Corresponding Source for a work in source code form is that same work. 0132 0133 2. Basic Permissions. 0134 All rights granted under this License are granted for the term of copyright 0135 on the Program, and are irrevocable provided the stated conditions are met. 0136 This License explicitly affirms your unlimited permission to run the unmodified 0137 Program. The output from running a covered work is covered by this License 0138 only if the output, given its content, constitutes a covered work. This License 0139 acknowledges your rights of fair use or other equivalent, as provided by copyright 0140 law. 0141 0142 You may make, run and propagate covered works that you do not convey, without 0143 conditions so long as your license otherwise remains in force. You may convey 0144 covered works to others for the sole purpose of having them make modifications 0145 exclusively for you, or provide you with facilities for running those works, 0146 provided that you comply with the terms of this License in conveying all material 0147 for which you do not control copyright. Those thus making or running the 0148 covered works for you must do so exclusively on your behalf, under your direction 0149 and control, on terms that prohibit them from making any copies of your copyrighted 0150 material outside their relationship with you. 0151 0152 Conveying under any other circumstances is permitted solely under the conditions 0153 stated below. Sublicensing is not allowed; section 10 makes it unnecessary. 0154 0155 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 0156 No covered work shall be deemed part of an effective technological measure 0157 under any applicable law fulfilling obligations under article 11 of the WIPO 0158 copyright treaty adopted on 20 December 1996, or similar laws prohibiting 0159 or restricting circumvention of such measures. 0160 0161 When you convey a covered work, you waive any legal power to forbid circumvention 0162 of technological measures to the extent such circumvention is effected by 0163 exercising rights under this License with respect to the covered work, and 0164 you disclaim any intention to limit operation or modification of the work 0165 as a means of enforcing, against the work's users, your or third parties' 0166 legal rights to forbid circumvention of technological measures. 0167 0168 4. Conveying Verbatim Copies. 0169 You may convey verbatim copies of the Program's source code as you receive 0170 it, in any medium, provided that you conspicuously and appropriately publish 0171 on each copy an appropriate copyright notice; keep intact all notices stating 0172 that this License and any non-permissive terms added in accord with section 0173 7 apply to the code; keep intact all notices of the absence of any warranty; 0174 and give all recipients a copy of this License along with the Program. 0175 0176 You may charge any price or no price for each copy that you convey, and you 0177 may offer support or warranty protection for a fee. 0178 0179 5. Conveying Modified Source Versions. 0180 You may convey a work based on the Program, or the modifications to produce 0181 it from the Program, in the form of source code under the terms of section 0182 4, provided that you also meet all of these conditions: 0183 0184 a) The work must carry prominent notices stating that you modified it, and 0185 giving a relevant date. 0186 0187 b) The work must carry prominent notices stating that it is released under 0188 this License and any conditions added under section 7. This requirement modifies 0189 the requirement in section 4 to "keep intact all notices". 0190 0191 c) You must license the entire work, as a whole, under this License to anyone 0192 who comes into possession of a copy. This License will therefore apply, along 0193 with any applicable section 7 additional terms, to the whole of the work, 0194 and all its parts, regardless of how they are packaged. This License gives 0195 no permission to license the work in any other way, but it does not invalidate 0196 such permission if you have separately received it. 0197 0198 d) If the work has interactive user interfaces, each must display Appropriate 0199 Legal Notices; however, if the Program has interactive interfaces that do 0200 not display Appropriate Legal Notices, your work need not make them do so. 0201 0202 A compilation of a covered work with other separate and independent works, 0203 which are not by their nature extensions of the covered work, and which are 0204 not combined with it such as to form a larger program, in or on a volume of 0205 a storage or distribution medium, is called an "aggregate" if the compilation 0206 and its resulting copyright are not used to limit the access or legal rights 0207 of the compilation's users beyond what the individual works permit. Inclusion 0208 of a covered work in an aggregate does not cause this License to apply to 0209 the other parts of the aggregate. 0210 0211 6. Conveying Non-Source Forms. 0212 You may convey a covered work in object code form under the terms of sections 0213 4 and 5, provided that you also convey the machine-readable Corresponding 0214 Source under the terms of this License, in one of these ways: 0215 0216 a) Convey the object code in, or embodied in, a physical product (including 0217 a physical distribution medium), accompanied by the Corresponding Source fixed 0218 on a durable physical medium customarily used for software interchange. 0219 0220 b) Convey the object code in, or embodied in, a physical product (including 0221 a physical distribution medium), accompanied by a written offer, valid for 0222 at least three years and valid for as long as you offer spare parts or customer 0223 support for that product model, to give anyone who possesses the object code 0224 either (1) a copy of the Corresponding Source for all the software in the 0225 product that is covered by this License, on a durable physical medium customarily 0226 used for software interchange, for a price no more than your reasonable cost 0227 of physically performing this conveying of source, or (2) access to copy the 0228 Corresponding Source from a network server at no charge. 0229 0230 c) Convey individual copies of the object code with a copy of the written 0231 offer to provide the Corresponding Source. This alternative is allowed only 0232 occasionally and noncommercially, and only if you received the object code 0233 with such an offer, in accord with subsection 6b. 0234 0235 d) Convey the object code by offering access from a designated place (gratis 0236 or for a charge), and offer equivalent access to the Corresponding Source 0237 in the same way through the same place at no further charge. You need not 0238 require recipients to copy the Corresponding Source along with the object 0239 code. If the place to copy the object code is a network server, the Corresponding 0240 Source may be on a different server (operated by you or a third party) that 0241 supports equivalent copying facilities, provided you maintain clear directions 0242 next to the object code saying where to find the Corresponding Source. Regardless 0243 of what server hosts the Corresponding Source, you remain obligated to ensure 0244 that it is available for as long as needed to satisfy these requirements. 0245 0246 e) Convey the object code using peer-to-peer transmission, provided you inform 0247 other peers where the object code and Corresponding Source of the work are 0248 being offered to the general public at no charge under subsection 6d. 0249 0250 A separable portion of the object code, whose source code is excluded from 0251 the Corresponding Source as a System Library, need not be included in conveying 0252 the object code work. 0253 0254 A "User Product" is either (1) a "consumer product", which means any tangible 0255 personal property which is normally used for personal, family, or household 0256 purposes, or (2) anything designed or sold for incorporation into a dwelling. 0257 In determining whether a product is a consumer product, doubtful cases shall 0258 be resolved in favor of coverage. For a particular product received by a 0259 particular user, "normally used" refers to a typical or common use of that 0260 class of product, regardless of the status of the particular user or of the 0261 way in which the particular user actually uses, or expects or is expected 0262 to use, the product. A product is a consumer product regardless of whether 0263 the product has substantial commercial, industrial or non-consumer uses, unless 0264 such uses represent the only significant mode of use of the product. 0265 0266 "Installation Information" for a User Product means any methods, procedures, 0267 authorization keys, or other information required to install and execute modified 0268 versions of a covered work in that User Product from a modified version of 0269 its Corresponding Source. The information must suffice to ensure that the 0270 continued functioning of the modified object code is in no case prevented 0271 or interfered with solely because modification has been made. 0272 0273 If you convey an object code work under this section in, or with, or specifically 0274 for use in, a User Product, and the conveying occurs as part of a transaction 0275 in which the right of possession and use of the User Product is transferred 0276 to the recipient in perpetuity or for a fixed term (regardless of how the 0277 transaction is characterized), the Corresponding Source conveyed under this 0278 section must be accompanied by the Installation Information. But this requirement 0279 does not apply if neither you nor any third party retains the ability to install 0280 modified object code on the User Product (for example, the work has been installed 0281 in ROM). 0282 0283 The requirement to provide Installation Information does not include a requirement 0284 to continue to provide support service, warranty, or updates for a work that 0285 has been modified or installed by the recipient, or for the User Product in 0286 which it has been modified or installed. Access to a network may be denied 0287 when the modification itself materially and adversely affects the operation 0288 of the network or violates the rules and protocols for communication across 0289 the network. 0290 0291 Corresponding Source conveyed, and Installation Information provided, in accord 0292 with this section must be in a format that is publicly documented (and with 0293 an implementation available to the public in source code form), and must require 0294 no special password or key for unpacking, reading or copying. 0295 0296 7. Additional Terms. 0297 "Additional permissions" are terms that supplement the terms of this License 0298 by making exceptions from one or more of its conditions. Additional permissions 0299 that are applicable to the entire Program shall be treated as though they 0300 were included in this License, to the extent that they are valid under applicable 0301 law. If additional permissions apply only to part of the Program, that part 0302 may be used separately under those permissions, but the entire Program remains 0303 governed by this License without regard to the additional permissions. 0304 0305 When you convey a copy of a covered work, you may at your option remove any 0306 additional permissions from that copy, or from any part of it. (Additional 0307 permissions may be written to require their own removal in certain cases when 0308 you modify the work.) You may place additional permissions on material, added 0309 by you to a covered work, for which you have or can give appropriate copyright 0310 permission. 0311 0312 Notwithstanding any other provision of this License, for material you add 0313 to a covered work, you may (if authorized by the copyright holders of that 0314 material) supplement the terms of this License with terms: 0315 0316 a) Disclaiming warranty or limiting liability differently from the terms of 0317 sections 15 and 16 of this License; or 0318 0319 b) Requiring preservation of specified reasonable legal notices or author 0320 attributions in that material or in the Appropriate Legal Notices displayed 0321 by works containing it; or 0322 0323 c) Prohibiting misrepresentation of the origin of that material, or requiring 0324 that modified versions of such material be marked in reasonable ways as different 0325 from the original version; or 0326 0327 d) Limiting the use for publicity purposes of names of licensors or authors 0328 of the material; or 0329 0330 e) Declining to grant rights under trademark law for use of some trade names, 0331 trademarks, or service marks; or 0332 0333 f) Requiring indemnification of licensors and authors of that material by 0334 anyone who conveys the material (or modified versions of it) with contractual 0335 assumptions of liability to the recipient, for any liability that these contractual 0336 assumptions directly impose on those licensors and authors. 0337 0338 All other non-permissive additional terms are considered "further restrictions" 0339 within the meaning of section 10. If the Program as you received it, or any 0340 part of it, contains a notice stating that it is governed by this License 0341 along with a term that is a further restriction, you may remove that term. 0342 If a license document contains a further restriction but permits relicensing 0343 or conveying under this License, you may add to a covered work material governed 0344 by the terms of that license document, provided that the further restriction 0345 does not survive such relicensing or conveying. 0346 0347 If you add terms to a covered work in accord with this section, you must place, 0348 in the relevant source files, a statement of the additional terms that apply 0349 to those files, or a notice indicating where to find the applicable terms. 0350 0351 Additional terms, permissive or non-permissive, may be stated in the form 0352 of a separately written license, or stated as exceptions; the above requirements 0353 apply either way. 0354 0355 8. Termination. 0356 0357 You may not propagate or modify a covered work except as expressly provided 0358 under this License. Any attempt otherwise to propagate or modify it is void, 0359 and will automatically terminate your rights under this License (including 0360 any patent licenses granted under the third paragraph of section 11). 0361 0362 However, if you cease all violation of this License, then your license from 0363 a particular copyright holder is reinstated (a) provisionally, unless and 0364 until the copyright holder explicitly and finally terminates your license, 0365 and (b) permanently, if the copyright holder fails to notify you of the violation 0366 by some reasonable means prior to 60 days after the cessation. 0367 0368 Moreover, your license from a particular copyright holder is reinstated permanently 0369 if the copyright holder notifies you of the violation by some reasonable means, 0370 this is the first time you have received notice of violation of this License 0371 (for any work) from that copyright holder, and you cure the violation prior 0372 to 30 days after your receipt of the notice. 0373 0374 Termination of your rights under this section does not terminate the licenses 0375 of parties who have received copies or rights from you under this License. 0376 If your rights have been terminated and not permanently reinstated, you do 0377 not qualify to receive new licenses for the same material under section 10. 0378 0379 9. Acceptance Not Required for Having Copies. 0380 0381 You are not required to accept this License in order to receive or run a copy 0382 of the Program. Ancillary propagation of a covered work occurring solely 0383 as a consequence of using peer-to-peer transmission to receive a copy likewise 0384 does not require acceptance. However, nothing other than this License grants 0385 you permission to propagate or modify any covered work. These actions infringe 0386 copyright if you do not accept this License. Therefore, by modifying or propagating 0387 a covered work, you indicate your acceptance of this License to do so. 0388 0389 10. Automatic Licensing of Downstream Recipients. 0390 0391 Each time you convey a covered work, the recipient automatically receives 0392 a license from the original licensors, to run, modify and propagate that work, 0393 subject to this License. You are not responsible for enforcing compliance 0394 by third parties with this License. 0395 0396 An "entity transaction" is a transaction transferring control of an organization, 0397 or substantially all assets of one, or subdividing an organization, or merging 0398 organizations. If propagation of a covered work results from an entity transaction, 0399 each party to that transaction who receives a copy of the work also receives 0400 whatever licenses to the work the party's predecessor in interest had or could 0401 give under the previous paragraph, plus a right to possession of the Corresponding 0402 Source of the work from the predecessor in interest, if the predecessor has 0403 it or can get it with reasonable efforts. 0404 0405 You may not impose any further restrictions on the exercise of the rights 0406 granted or affirmed under this License. For example, you may not impose a 0407 license fee, royalty, or other charge for exercise of rights granted under 0408 this License, and you may not initiate litigation (including a cross-claim 0409 or counterclaim in a lawsuit) alleging that any patent claim is infringed 0410 by making, using, selling, offering for sale, or importing the Program or 0411 any portion of it. 0412 0413 11. Patents. 0414 0415 A "contributor" is a copyright holder who authorizes use under this License 0416 of the Program or a work on which the Program is based. The work thus licensed 0417 is called the contributor's "contributor version". 0418 0419 A contributor's "essential patent claims" are all patent claims owned or controlled 0420 by the contributor, whether already acquired or hereafter acquired, that would 0421 be infringed by some manner, permitted by this License, of making, using, 0422 or selling its contributor version, but do not include claims that would be 0423 infringed only as a consequence of further modification of the contributor 0424 version. For purposes of this definition, "control" includes the right to 0425 grant patent sublicenses in a manner consistent with the requirements of this 0426 License. 0427 0428 Each contributor grants you a non-exclusive, worldwide, royalty-free patent 0429 license under the contributor's essential patent claims, to make, use, sell, 0430 offer for sale, import and otherwise run, modify and propagate the contents 0431 of its contributor version. 0432 0433 In the following three paragraphs, a "patent license" is any express agreement 0434 or commitment, however denominated, not to enforce a patent (such as an express 0435 permission to practice a patent or covenant not to sue for patent infringement). 0436 To "grant" such a patent license to a party means to make such an agreement 0437 or commitment not to enforce a patent against the party. 0438 0439 If you convey a covered work, knowingly relying on a patent license, and the 0440 Corresponding Source of the work is not available for anyone to copy, free 0441 of charge and under the terms of this License, through a publicly available 0442 network server or other readily accessible means, then you must either (1) 0443 cause the Corresponding Source to be so available, or (2) arrange to deprive 0444 yourself of the benefit of the patent license for this particular work, or 0445 (3) arrange, in a manner consistent with the requirements of this License, 0446 to extend the patent 0447 license to downstream recipients. "Knowingly relying" means you have actual 0448 knowledge that, but for the patent license, your conveying the covered work 0449 in a country, or your recipient's use of the covered work in a country, would 0450 infringe one or more identifiable patents in that country that you have reason 0451 to believe are valid. 0452 0453 If, pursuant to or in connection with a single transaction or arrangement, 0454 you convey, or propagate by procuring conveyance of, a covered work, and grant 0455 a patent license to some of the parties receiving the covered work authorizing 0456 them to use, propagate, modify or convey a specific copy of the covered work, 0457 then the patent license you grant is automatically extended to all recipients 0458 of the covered work and works based on it. 0459 0460 A patent license is "discriminatory" if it does not include within the scope 0461 of its coverage, prohibits the exercise of, or is conditioned on the non-exercise 0462 of one or more of the rights that are specifically granted under this License. 0463 You may not convey a covered work if you are a party to an arrangement with 0464 a third party that is in the business of distributing software, under which 0465 you make payment to the third party based on the extent of your activity of 0466 conveying the work, and under which the third party grants, to any of the 0467 parties who would receive the covered work from you, a discriminatory patent 0468 license (a) in connection with copies of the covered work conveyed by you 0469 (or copies made from those copies), or (b) primarily for and in connection 0470 with specific products or compilations that contain the covered work, unless 0471 you entered into that arrangement, or that patent license was granted, prior 0472 to 28 March 2007. 0473 0474 Nothing in this License shall be construed as excluding or limiting any implied 0475 license or other defenses to infringement that may otherwise be available 0476 to you under applicable patent law. 0477 0478 12. No Surrender of Others' Freedom. 0479 0480 If conditions are imposed on you (whether by court order, agreement or otherwise) 0481 that contradict the conditions of this License, they do not excuse you from 0482 the conditions of this License. If you cannot convey a covered work so as 0483 to satisfy simultaneously your obligations under this License and any other 0484 pertinent obligations, then as a consequence you may 0485 not convey it at all. For example, if you agree to terms that obligate you 0486 to collect a royalty for further conveying from those to whom you convey the 0487 Program, the only way you could satisfy both those terms and this License 0488 would be to refrain entirely from conveying the Program. 0489 0490 13. Remote Network Interaction; Use with the GNU General Public License. 0491 0492 Notwithstanding any other provision of this License, if you modify the Program, 0493 your modified version must prominently offer all users interacting with it 0494 remotely through a computer network (if your version supports such interaction) 0495 an opportunity to receive the Corresponding Source of your version by providing 0496 access to the Corresponding Source from a network server at no charge, through 0497 some standard or customary means of facilitating copying of software. This 0498 Corresponding Source shall include the Corresponding Source for any work covered 0499 by version 3 of the GNU General Public License that is incorporated pursuant 0500 to the following paragraph. 0501 0502 Notwithstanding any other provision of this License, you have permission to 0503 link or combine any covered work with a work licensed under version 3 of the 0504 GNU General Public License into a single combined work, and to convey the 0505 resulting work. The terms of this License will continue to apply to the part 0506 which is the covered work, but the work with which it is combined will remain 0507 governed by version 3 of the GNU General Public License. 0508 0509 14. Revised Versions of this License. 0510 0511 The Free Software Foundation may publish revised and/or new versions of the 0512 GNU Affero General Public License from time to time. Such new versions will 0513 be similar in spirit to the present version, but may differ in detail to address 0514 new problems or concerns. 0515 0516 Each version is given a distinguishing version number. If the Program specifies 0517 that a certain numbered version of the GNU Affero General Public License "or 0518 any later version" applies to it, you have the option of following the terms 0519 and conditions either of that numbered version or of any later version published 0520 by the Free Software Foundation. If the Program does not specify a version 0521 number of the GNU Affero General Public License, you may choose any version 0522 ever published by the Free Software Foundation. 0523 0524 If the Program specifies that a proxy can decide which future versions of 0525 the GNU Affero General Public License can be used, that proxy's public statement 0526 of acceptance of a version permanently authorizes you to choose that version 0527 for the Program. 0528 0529 Later license versions may give you additional or different permissions. 0530 However, no additional obligations are imposed on any author or copyright 0531 holder as a result of your choosing to follow a later version. 0532 0533 15. Disclaimer of Warranty. 0534 0535 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE 0536 LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR 0537 OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER 0538 EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES 0539 OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK 0540 AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 0541 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR 0542 OR CORRECTION. 0543 0544 16. Limitation of Liability. 0545 0546 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL 0547 ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM 0548 AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, 0549 INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO 0550 USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED 0551 INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE 0552 PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER 0553 PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 0554 0555 17. Interpretation of Sections 15 and 16. 0556 0557 If the disclaimer of warranty and limitation of liability provided above cannot 0558 be given local legal effect according to their terms, reviewing courts shall 0559 apply local law that most closely approximates an absolute waiver of all civil 0560 liability in connection with the Program, unless a warranty or assumption 0561 of liability accompanies a copy of the Program in return for a fee. 0562 0563 END OF TERMS AND CONDITIONS 0564 0565 How to Apply These Terms to Your New Programs 0566 0567 If you develop a new program, and you want it to be of the greatest possible 0568 use to the public, the best way to achieve this is to make it free software 0569 which everyone can redistribute and change under these terms. 0570 0571 To do so, attach the following notices to the program. It is safest to attach 0572 them to the start of each source file to most effectively state the exclusion 0573 of warranty; and each file should have at least the "copyright" line and a 0574 pointer to where the full notice is found. 0575 0576 <one line to give the program's name and a brief idea of what it does.> 0577 Copyright (C) <year> <name of author> 0578 0579 This program is free software: you can redistribute it and/or modify it under 0580 the terms of the GNU Affero General Public License as published by the Free 0581 Software Foundation, either version 3 of the License, or (at your option) 0582 any later version. 0583 0584 This program is distributed in the hope that it will be useful, but WITHOUT 0585 ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS 0586 FOR A PARTICULAR PURPOSE. See the GNU Affero General Public License for more 0587 details. 0588 0589 You should have received a copy of the GNU Affero General Public License along 0590 with this program. If not, see <http://www.gnu.org/licenses/>. 0591 0592 Also add information on how to contact you by electronic and paper mail. 0593 0594 If your software can interact with users remotely through a computer network, 0595 you should also make sure that it provides a way for users to get its source. 0596 For example, if your program is a web application, its interface could display 0597 a "Source" link that leads users to an archive of the code. There are many 0598 ways you could offer source, and different solutions will be better for different 0599 programs; see section 13 for the specific requirements. 0600 0601 You should also get your employer (if you work as a programmer) or school, 0602 if any, to sign a "copyright disclaimer" for the program, if necessary.
