1 GNU AFFERO GENERAL PUBLIC LICENSE 2 Version 3, 19 November 2007 3 4 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 5 Everyone is permitted to copy and distribute verbatim copies 6 of this license document, but changing it is not allowed. 7 8 Preamble 9 10 The GNU Affero General Public License is a free, copyleft license for 11software and other kinds of works, specifically designed to ensure 12cooperation with the community in the case of network server software. 13 14 The licenses for most software and other practical works are designed 15to take away your freedom to share and change the works. By contrast, 16our General Public Licenses are intended to guarantee your freedom to 17share and change all versions of a program--to make sure it remains free 18software for all its users. 19 20 When we speak of free software, we are referring to freedom, not 21price. Our General Public Licenses are designed to make sure that you 22have the freedom to distribute copies of free software (and charge for 23them if you wish), that you receive source code or can get it if you 24want it, that you can change the software or use pieces of it in new 25free programs, and that you know you can do these things. 26 27 Developers that use our General Public Licenses protect your rights 28with two steps: (1) assert copyright on the software, and (2) offer 29you this License which gives you legal permission to copy, distribute 30and/or modify the software. 31 32 A secondary benefit of defending all users' freedom is that 33improvements made in alternate versions of the program, if they 34receive widespread use, become available for other developers to 35incorporate. Many developers of free software are heartened and 36encouraged by the resulting cooperation. However, in the case of 37software used on network servers, this result may fail to come about. 38The GNU General Public License permits making a modified version and 39letting the public access it on a server without ever releasing its 40source code to the public. 41 42 The GNU Affero General Public License is designed specifically to 43ensure that, in such cases, the modified source code becomes available 44to the community. It requires the operator of a network server to 45provide the source code of the modified version running there to the 46users of that server. Therefore, public use of a modified version, on 47a publicly accessible server, gives the public access to the source 48code of the modified version. 49 50 An older license, called the Affero General Public License and 51published by Affero, was designed to accomplish similar goals. This is 52a different license, not a version of the Affero GPL, but Affero has 53released a new version of the Affero GPL which permits relicensing under 54this license. 55 56 The precise terms and conditions for copying, distribution and 57modification follow. 58 59 TERMS AND CONDITIONS 60 61 0. Definitions. 62 63 "This License" refers to version 3 of the GNU Affero General Public License. 64 65 "Copyright" also means copyright-like laws that apply to other kinds of 66works, such as semiconductor masks. 67 68 "The Program" refers to any copyrightable work licensed under this 69License. Each licensee is addressed as "you". "Licensees" and 70"recipients" may be individuals or organizations. 71 72 To "modify" a work means to copy from or adapt all or part of the work 73in a fashion requiring copyright permission, other than the making of an 74exact copy. The resulting work is called a "modified version" of the 75earlier work or a work "based on" the earlier work. 76 77 A "covered work" means either the unmodified Program or a work based 78on the Program. 79 80 To "propagate" a work means to do anything with it that, without 81permission, would make you directly or secondarily liable for 82infringement under applicable copyright law, except executing it on a 83computer or modifying a private copy. Propagation includes copying, 84distribution (with or without modification), making available to the 85public, and in some countries other activities as well. 86 87 To "convey" a work means any kind of propagation that enables other 88parties to make or receive copies. Mere interaction with a user through 89a computer network, with no transfer of a copy, is not conveying. 90 91 An interactive user interface displays "Appropriate Legal Notices" 92to the extent that it includes a convenient and prominently visible 93feature that (1) displays an appropriate copyright notice, and (2) 94tells the user that there is no warranty for the work (except to the 95extent that warranties are provided), that licensees may convey the 96work under this License, and how to view a copy of this License. If 97the interface presents a list of user commands or options, such as a 98menu, a prominent item in the list meets this criterion. 99100 1. Source Code.101102 The "source code" for a work means the preferred form of the work103for making modifications to it. "Object code" means any non-source104form of a work.105106 A "Standard Interface" means an interface that either is an official107standard defined by a recognized standards body, or, in the case of108interfaces specified for a particular programming language, one that109is widely used among developers working in that language.110111 The "System Libraries" of an executable work include anything, other112than the work as a whole, that (a) is included in the normal form of113packaging a Major Component, but which is not part of that Major114Component, and (b) serves only to enable use of the work with that115Major Component, or to implement a Standard Interface for which an116implementation is available to the public in source code form. A117"Major Component", in this context, means a major essential component118(kernel, window system, and so on) of the specific operating system119(if any) on which the executable work runs, or a compiler used to120produce the work, or an object code interpreter used to run it.121122 The "Corresponding Source" for a work in object code form means all123the source code needed to generate, install, and (for an executable124work) run the object code and to modify the work, including scripts to125control those activities. However, it does not include the work's126System Libraries, or general-purpose tools or generally available free127programs which are used unmodified in performing those activities but128which are not part of the work. For example, Corresponding Source129includes interface definition files associated with source files for130the work, and the source code for shared libraries and dynamically131linked subprograms that the work is specifically designed to require,132such as by intimate data communication or control flow between those133subprograms and other parts of the work.134135 The Corresponding Source need not include anything that users136can regenerate automatically from other parts of the Corresponding137Source.138139 The Corresponding Source for a work in source code form is that140same work.141142 2. Basic Permissions.143144 All rights granted under this License are granted for the term of145copyright on the Program, and are irrevocable provided the stated146conditions are met. This License explicitly affirms your unlimited147permission to run the unmodified Program. The output from running a148covered work is covered by this License only if the output, given its149content, constitutes a covered work. This License acknowledges your150rights of fair use or other equivalent, as provided by copyright law.151152 You may make, run and propagate covered works that you do not153convey, without conditions so long as your license otherwise remains154in force. You may convey covered works to others for the sole purpose155of having them make modifications exclusively for you, or provide you156with facilities for running those works, provided that you comply with157the terms of this License in conveying all material for which you do158not control copyright. Those thus making or running the covered works159for you must do so exclusively on your behalf, under your direction160and control, on terms that prohibit them from making any copies of161your copyrighted material outside their relationship with you.162163 Conveying under any other circumstances is permitted solely under164the conditions stated below. Sublicensing is not allowed; section 10165makes it unnecessary.166167 3. Protecting Users' Legal Rights From Anti-Circumvention Law.168169 No covered work shall be deemed part of an effective technological170measure under any applicable law fulfilling obligations under article17111 of the WIPO copyright treaty adopted on 20 December 1996, or172similar laws prohibiting or restricting circumvention of such173measures.174175 When you convey a covered work, you waive any legal power to forbid176circumvention of technological measures to the extent such circumvention177is effected by exercising rights under this License with respect to178the covered work, and you disclaim any intention to limit operation or179modification of the work as a means of enforcing, against the work's180users, your or third parties' legal rights to forbid circumvention of181technological measures.182183 4. Conveying Verbatim Copies.184185 You may convey verbatim copies of the Program's source code as you186receive it, in any medium, provided that you conspicuously and187appropriately publish on each copy an appropriate copyright notice;188keep intact all notices stating that this License and any189non-permissive terms added in accord with section 7 apply to the code;190keep intact all notices of the absence of any warranty; and give all191recipients a copy of this License along with the Program.192193 You may charge any price or no price for each copy that you convey,194and you may offer support or warranty protection for a fee.195196 5. Conveying Modified Source Versions.197198 You may convey a work based on the Program, or the modifications to199produce it from the Program, in the form of source code under the200terms of section 4, provided that you also meet all of these conditions:201202 a) The work must carry prominent notices stating that you modified203 it, and giving a relevant date.204205 b) The work must carry prominent notices stating that it is206 released under this License and any conditions added under section207 7. This requirement modifies the requirement in section 4 to208 "keep intact all notices".209210 c) You must license the entire work, as a whole, under this211 License to anyone who comes into possession of a copy. This212 License will therefore apply, along with any applicable section 7213 additional terms, to the whole of the work, and all its parts,214 regardless of how they are packaged. This License gives no215 permission to license the work in any other way, but it does not216 invalidate such permission if you have separately received it.217218 d) If the work has interactive user interfaces, each must display219 Appropriate Legal Notices; however, if the Program has interactive220 interfaces that do not display Appropriate Legal Notices, your221 work need not make them do so.222223 A compilation of a covered work with other separate and independent224works, which are not by their nature extensions of the covered work,225and which are not combined with it such as to form a larger program,226in or on a volume of a storage or distribution medium, is called an227"aggregate" if the compilation and its resulting copyright are not228used to limit the access or legal rights of the compilation's users229beyond what the individual works permit. Inclusion of a covered work230in an aggregate does not cause this License to apply to the other231parts of the aggregate.232233 6. Conveying Non-Source Forms.234235 You may convey a covered work in object code form under the terms236of sections 4 and 5, provided that you also convey the237machine-readable Corresponding Source under the terms of this License,238in one of these ways:239240 a) Convey the object code in, or embodied in, a physical product241 (including a physical distribution medium), accompanied by the242 Corresponding Source fixed on a durable physical medium243 customarily used for software interchange.244245 b) Convey the object code in, or embodied in, a physical product246 (including a physical distribution medium), accompanied by a247 written offer, valid for at least three years and valid for as248 long as you offer spare parts or customer support for that product249 model, to give anyone who possesses the object code either (1) a250 copy of the Corresponding Source for all the software in the251 product that is covered by this License, on a durable physical252 medium customarily used for software interchange, for a price no253 more than your reasonable cost of physically performing this254 conveying of source, or (2) access to copy the255 Corresponding Source from a network server at no charge.256257 c) Convey individual copies of the object code with a copy of the258 written offer to provide the Corresponding Source. This259 alternative is allowed only occasionally and noncommercially, and260 only if you received the object code with such an offer, in accord261 with subsection 6b.262263 d) Convey the object code by offering access from a designated264 place (gratis or for a charge), and offer equivalent access to the265 Corresponding Source in the same way through the same place at no266 further charge. You need not require recipients to copy the267 Corresponding Source along with the object code. If the place to268 copy the object code is a network server, the Corresponding Source269 may be on a different server (operated by you or a third party)270 that supports equivalent copying facilities, provided you maintain271 clear directions next to the object code saying where to find the272 Corresponding Source. Regardless of what server hosts the273 Corresponding Source, you remain obligated to ensure that it is274 available for as long as needed to satisfy these requirements.275276 e) Convey the object code using peer-to-peer transmission, provided277 you inform other peers where the object code and Corresponding278 Source of the work are being offered to the general public at no279 charge under subsection 6d.280281 A separable portion of the object code, whose source code is excluded282from the Corresponding Source as a System Library, need not be283included in conveying the object code work.284285 A "User Product" is either (1) a "consumer product", which means any286tangible personal property which is normally used for personal, family,287or household purposes, or (2) anything designed or sold for incorporation288into a dwelling. In determining whether a product is a consumer product,289doubtful cases shall be resolved in favor of coverage. For a particular290product received by a particular user, "normally used" refers to a291typical or common use of that class of product, regardless of the status292of the particular user or of the way in which the particular user293actually uses, or expects or is expected to use, the product. A product294is a consumer product regardless of whether the product has substantial295commercial, industrial or non-consumer uses, unless such uses represent296the only significant mode of use of the product.297298 "Installation Information" for a User Product means any methods,299procedures, authorization keys, or other information required to install300and execute modified versions of a covered work in that User Product from301a modified version of its Corresponding Source. The information must302suffice to ensure that the continued functioning of the modified object303code is in no case prevented or interfered with solely because304modification has been made.305306 If you convey an object code work under this section in, or with, or307specifically for use in, a User Product, and the conveying occurs as308part of a transaction in which the right of possession and use of the309User Product is transferred to the recipient in perpetuity or for a310fixed term (regardless of how the transaction is characterized), the311Corresponding Source conveyed under this section must be accompanied312by the Installation Information. But this requirement does not apply313if neither you nor any third party retains the ability to install314modified object code on the User Product (for example, the work has315been installed in ROM).316317 The requirement to provide Installation Information does not include a318requirement to continue to provide support service, warranty, or updates319for a work that has been modified or installed by the recipient, or for320the User Product in which it has been modified or installed. Access to a321network may be denied when the modification itself materially and322adversely affects the operation of the network or violates the rules and323protocols for communication across the network.324325 Corresponding Source conveyed, and Installation Information provided,326in accord with this section must be in a format that is publicly327documented (and with an implementation available to the public in328source code form), and must require no special password or key for329unpacking, reading or copying.330331 7. Additional Terms.332333 "Additional permissions" are terms that supplement the terms of this334License by making exceptions from one or more of its conditions.335Additional permissions that are applicable to the entire Program shall336be treated as though they were included in this License, to the extent337that they are valid under applicable law. If additional permissions338apply only to part of the Program, that part may be used separately339under those permissions, but the entire Program remains governed by340this License without regard to the additional permissions.341342 When you convey a copy of a covered work, you may at your option343remove any additional permissions from that copy, or from any part of344it. (Additional permissions may be written to require their own345removal in certain cases when you modify the work.) You may place346additional permissions on material, added by you to a covered work,347for which you have or can give appropriate copyright permission.348349 Notwithstanding any other provision of this License, for material you350add to a covered work, you may (if authorized by the copyright holders of351that material) supplement the terms of this License with terms:352353 a) Disclaiming warranty or limiting liability differently from the354 terms of sections 15 and 16 of this License; or355356 b) Requiring preservation of specified reasonable legal notices or357 author attributions in that material or in the Appropriate Legal358 Notices displayed by works containing it; or359360 c) Prohibiting misrepresentation of the origin of that material, or361 requiring that modified versions of such material be marked in362 reasonable ways as different from the original version; or363364 d) Limiting the use for publicity purposes of names of licensors or365 authors of the material; or366367 e) Declining to grant rights under trademark law for use of some368 trade names, trademarks, or service marks; or369370 f) Requiring indemnification of licensors and authors of that371 material by anyone who conveys the material (or modified versions of372 it) with contractual assumptions of liability to the recipient, for373 any liability that these contractual assumptions directly impose on374 those licensors and authors.375376 All other non-permissive additional terms are considered "further377restrictions" within the meaning of section 10. If the Program as you378received it, or any part of it, contains a notice stating that it is379governed by this License along with a term that is a further380restriction, you may remove that term. If a license document contains381a further restriction but permits relicensing or conveying under this382License, you may add to a covered work material governed by the terms383of that license document, provided that the further restriction does384not survive such relicensing or conveying.385386 If you add terms to a covered work in accord with this section, you387must place, in the relevant source files, a statement of the388additional terms that apply to those files, or a notice indicating389where to find the applicable terms.390391 Additional terms, permissive or non-permissive, may be stated in the392form of a separately written license, or stated as exceptions;393the above requirements apply either way.394395 8. Termination.396397 You may not propagate or modify a covered work except as expressly398provided under this License. Any attempt otherwise to propagate or399modify it is void, and will automatically terminate your rights under400this License (including any patent licenses granted under the third401paragraph of section 11).402403 However, if you cease all violation of this License, then your404license from a particular copyright holder is reinstated (a)405provisionally, unless and until the copyright holder explicitly and406finally terminates your license, and (b) permanently, if the copyright407holder fails to notify you of the violation by some reasonable means408prior to 60 days after the cessation.409410 Moreover, your license from a particular copyright holder is411reinstated permanently if the copyright holder notifies you of the412violation by some reasonable means, this is the first time you have413received notice of violation of this License (for any work) from that414copyright holder, and you cure the violation prior to 30 days after415your receipt of the notice.416417 Termination of your rights under this section does not terminate the418licenses of parties who have received copies or rights from you under419this License. If your rights have been terminated and not permanently420reinstated, you do not qualify to receive new licenses for the same421material under section 10.422423 9. Acceptance Not Required for Having Copies.424425 You are not required to accept this License in order to receive or426run a copy of the Program. Ancillary propagation of a covered work427occurring solely as a consequence of using peer-to-peer transmission428to receive a copy likewise does not require acceptance. However,429nothing other than this License grants you permission to propagate or430modify any covered work. These actions infringe copyright if you do431not accept this License. Therefore, by modifying or propagating a432covered work, you indicate your acceptance of this License to do so.433434 10. Automatic Licensing of Downstream Recipients.435436 Each time you convey a covered work, the recipient automatically437receives a license from the original licensors, to run, modify and438propagate that work, subject to this License. You are not responsible439for enforcing compliance by third parties with this License.440441 An "entity transaction" is a transaction transferring control of an442organization, or substantially all assets of one, or subdividing an443organization, or merging organizations. If propagation of a covered444work results from an entity transaction, each party to that445transaction who receives a copy of the work also receives whatever446licenses to the work the party's predecessor in interest had or could447give under the previous paragraph, plus a right to possession of the448Corresponding Source of the work from the predecessor in interest, if449the predecessor has it or can get it with reasonable efforts.450451 You may not impose any further restrictions on the exercise of the452rights granted or affirmed under this License. For example, you may453not impose a license fee, royalty, or other charge for exercise of454rights granted under this License, and you may not initiate litigation455(including a cross-claim or counterclaim in a lawsuit) alleging that456any patent claim is infringed by making, using, selling, offering for457sale, or importing the Program or any portion of it.458459 11. Patents.460461 A "contributor" is a copyright holder who authorizes use under this462License of the Program or a work on which the Program is based. The463work thus licensed is called the contributor's "contributor version".464465 A contributor's "essential patent claims" are all patent claims466owned or controlled by the contributor, whether already acquired or467hereafter acquired, that would be infringed by some manner, permitted468by this License, of making, using, or selling its contributor version,469but do not include claims that would be infringed only as a470consequence of further modification of the contributor version. For471purposes of this definition, "control" includes the right to grant472patent sublicenses in a manner consistent with the requirements of473this License.474475 Each contributor grants you a non-exclusive, worldwide, royalty-free476patent license under the contributor's essential patent claims, to477make, use, sell, offer for sale, import and otherwise run, modify and478propagate the contents of its contributor version.479480 In the following three paragraphs, a "patent license" is any express481agreement or commitment, however denominated, not to enforce a patent482(such as an express permission to practice a patent or covenant not to483sue for patent infringement). To "grant" such a patent license to a484party means to make such an agreement or commitment not to enforce a485patent against the party.486487 If you convey a covered work, knowingly relying on a patent license,488and the Corresponding Source of the work is not available for anyone489to copy, free of charge and under the terms of this License, through a490publicly available network server or other readily accessible means,491then you must either (1) cause the Corresponding Source to be so492available, or (2) arrange to deprive yourself of the benefit of the493patent license for this particular work, or (3) arrange, in a manner494consistent with the requirements of this License, to extend the patent495license to downstream recipients. "Knowingly relying" means you have496actual knowledge that, but for the patent license, your conveying the497covered work in a country, or your recipient's use of the covered work498in a country, would infringe one or more identifiable patents in that499country that you have reason to believe are valid.500501 If, pursuant to or in connection with a single transaction or502arrangement, you convey, or propagate by procuring conveyance of, a503covered work, and grant a patent license to some of the parties504receiving the covered work authorizing them to use, propagate, modify505or convey a specific copy of the covered work, then the patent license506you grant is automatically extended to all recipients of the covered507work and works based on it.508509 A patent license is "discriminatory" if it does not include within510the scope of its coverage, prohibits the exercise of, or is511conditioned on the non-exercise of one or more of the rights that are512specifically granted under this License. You may not convey a covered513work if you are a party to an arrangement with a third party that is514in the business of distributing software, under which you make payment515to the third party based on the extent of your activity of conveying516the work, and under which the third party grants, to any of the517parties who would receive the covered work from you, a discriminatory518patent license (a) in connection with copies of the covered work519conveyed by you (or copies made from those copies), or (b) primarily520for and in connection with specific products or compilations that521contain the covered work, unless you entered into that arrangement,522or that patent license was granted, prior to 28 March 2007.523524 Nothing in this License shall be construed as excluding or limiting525any implied license or other defenses to infringement that may526otherwise be available to you under applicable patent law.527528 12. No Surrender of Others' Freedom.529530 If conditions are imposed on you (whether by court order, agreement or531otherwise) that contradict the conditions of this License, they do not532excuse you from the conditions of this License. If you cannot convey a533covered work so as to satisfy simultaneously your obligations under this534License and any other pertinent obligations, then as a consequence you may535not convey it at all. For example, if you agree to terms that obligate you536to collect a royalty for further conveying from those to whom you convey537the Program, the only way you could satisfy both those terms and this538License would be to refrain entirely from conveying the Program.539540 13. Remote Network Interaction; Use with the GNU General Public License.541542 Notwithstanding any other provision of this License, if you modify the543Program, your modified version must prominently offer all users544interacting with it remotely through a computer network (if your version545supports such interaction) an opportunity to receive the Corresponding546Source of your version by providing access to the Corresponding Source547from a network server at no charge, through some standard or customary548means of facilitating copying of software. This Corresponding Source549shall include the Corresponding Source for any work covered by version 3550of the GNU General Public License that is incorporated pursuant to the551following paragraph.552553 Notwithstanding any other provision of this License, you have554permission to link or combine any covered work with a work licensed555under version 3 of the GNU General Public License into a single556combined work, and to convey the resulting work. The terms of this557License will continue to apply to the part which is the covered work,558but the work with which it is combined will remain governed by version5593 of the GNU General Public License.560561 14. Revised Versions of this License.562563 The Free Software Foundation may publish revised and/or new versions of564the GNU Affero General Public License from time to time. Such new versions565will be similar in spirit to the present version, but may differ in detail to566address new problems or concerns.567568 Each version is given a distinguishing version number. If the569Program specifies that a certain numbered version of the GNU Affero General570Public License "or any later version" applies to it, you have the571option of following the terms and conditions either of that numbered572version or of any later version published by the Free Software573Foundation. If the Program does not specify a version number of the574GNU Affero General Public License, you may choose any version ever published575by the Free Software Foundation.576577 If the Program specifies that a proxy can decide which future578versions of the GNU Affero General Public License can be used, that proxy's579public statement of acceptance of a version permanently authorizes you580to choose that version for the Program.581582 Later license versions may give you additional or different583permissions. However, no additional obligations are imposed on any584author or copyright holder as a result of your choosing to follow a585later version.586587 15. Disclaimer of Warranty.588589 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY590APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT591HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY592OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,593THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR594PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM595IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF596ALL NECESSARY SERVICING, REPAIR OR CORRECTION.597598 16. Limitation of Liability.599600 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING601WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS602THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY603GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE604USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF605DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD606PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),607EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF608SUCH DAMAGES.609610 17. Interpretation of Sections 15 and 16.611612 If the disclaimer of warranty and limitation of liability provided613above cannot be given local legal effect according to their terms,614reviewing courts shall apply local law that most closely approximates615an absolute waiver of all civil liability in connection with the616Program, unless a warranty or assumption of liability accompanies a617copy of the Program in return for a fee.618619 END OF TERMS AND CONDITIONS620621 How to Apply These Terms to Your New Programs622623 If you develop a new program, and you want it to be of the greatest624possible use to the public, the best way to achieve this is to make it625free software which everyone can redistribute and change under these terms.626627 To do so, attach the following notices to the program. It is safest628to attach them to the start of each source file to most effectively629state the exclusion of warranty; and each file should have at least630the "copyright" line and a pointer to where the full notice is found.631632 <one line to give the program's name and a brief idea of what it does.>633 Copyright (C) <year> <name of author>634635 This program is free software: you can redistribute it and/or modify636 it under the terms of the GNU Affero General Public License as published by637 the Free Software Foundation, either version 3 of the License, or638 (at your option) any later version.639640 This program is distributed in the hope that it will be useful,641 but WITHOUT ANY WARRANTY; without even the implied warranty of642 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

For example, if your program is a web application, its653interface could display a "Source" link that leads users to an archive654of the code. There are many ways you could offer source, and different655solutions will be better for different programs; see section 13 for the656specific requirements.657658 You should also get your employer (if you work as a programmer) or school,659if any, to sign a "copyright disclaimer" for the program, if necessary.660For more information on this, and how to apply and follow the GNU AGPL, see661<http://www.gnu.org/licenses/>.
