1### GNU AFFERO GENERAL PUBLIC LICENSE23Version 3, 19 November 200745Copyright (C) 2007 Free Software Foundation, Inc.6<https://fsf.org/>78Everyone is permitted to copy and distribute verbatim copies of this9license document, but changing it is not allowed.1011### Preamble1213The GNU Affero General Public License is a free, copyleft license for14software and other kinds of works, specifically designed to ensure15cooperation with the community in the case of network server software.1617The licenses for most software and other practical works are designed18to take away your freedom to share and change the works. By contrast,19our General Public Licenses are intended to guarantee your freedom to20share and change all versions of a program--to make sure it remains21free software for all its users.2223When we speak of free software, we are referring to freedom, not24price. Our General Public Licenses are designed to make sure that you25have the freedom to distribute copies of free software (and charge for26them if you wish), that you receive source code or can get it if you27want it, that you can change the software or use pieces of it in new28free programs, and that you know you can do these things.2930Developers that use our General Public Licenses protect your rights31with two steps: (1) assert copyright on the software, and (2) offer32you this License which gives you legal permission to copy, distribute33and/or modify the software.3435A secondary benefit of defending all users' freedom is that36improvements made in alternate versions of the program, if they37receive widespread use, become available for other developers to38incorporate. Many developers of free software are heartened and39encouraged by the resulting cooperation. However, in the case of40software used on network servers, this result may fail to come about.41The GNU General Public License permits making a modified version and42letting the public access it on a server without ever releasing its43source code to the public.4445The GNU Affero General Public License is designed specifically to46ensure that, in such cases, the modified source code becomes available47to the community. It requires the operator of a network server to48provide the source code of the modified version running there to the49users of that server. Therefore, public use of a modified version, on50a publicly accessible server, gives the public access to the source51code of the modified version.5253An older license, called the Affero General Public License and54published by Affero, was designed to accomplish similar goals. This is55a different license, not a version of the Affero GPL, but Affero has56released a new version of the Affero GPL which permits relicensing57under this license.5859The precise terms and conditions for copying, distribution and60modification follow.6162### TERMS AND CONDITIONS6364#### 0. Definitions.6566"This License" refers to version 3 of the GNU Affero General Public67License.6869"Copyright" also means copyright-like laws that apply to other kinds70of works, such as semiconductor masks.7172"The Program" refers to any copyrightable work licensed under this73License. Each licensee is addressed as "you". "Licensees" and74"recipients" may be individuals or organizations.7576To "modify" a work means to copy from or adapt all or part of the work77in a fashion requiring copyright permission, other than the making of78an exact copy. The resulting work is called a "modified version" of79the earlier work or a work "based on" the earlier work.8081A "covered work" means either the unmodified Program or a work based82on the Program.8384To "propagate" a work means to do anything with it that, without85permission, would make you directly or secondarily liable for86infringement under applicable copyright law, except executing it on a87computer or modifying a private copy. Propagation includes copying,88distribution (with or without modification), making available to the89public, and in some countries other activities as well.9091To "convey" a work means any kind of propagation that enables other92parties to make or receive copies. Mere interaction with a user93through a computer network, with no transfer of a copy, is not94conveying.9596An interactive user interface displays "Appropriate Legal Notices" to97the extent that it includes a convenient and prominently visible98feature that (1) displays an appropriate copyright notice, and (2)99tells the user that there is no warranty for the work (except to the100extent that warranties are provided), that licensees may convey the101work under this License, and how to view a copy of this License. If102the interface presents a list of user commands or options, such as a103menu, a prominent item in the list meets this criterion.104105#### 1. Source Code.106107The "source code" for a work means the preferred form of the work for108making modifications to it. "Object code" means any non-source form of109a work.110111A "Standard Interface" means an interface that either is an official112standard defined by a recognized standards body, or, in the case of113interfaces specified for a particular programming language, one that114is widely used among developers working in that language.115116The "System Libraries" of an executable work include anything, other117than the work as a whole, that (a) is included in the normal form of118packaging a Major Component, but which is not part of that Major119Component, and (b) serves only to enable use of the work with that120Major Component, or to implement a Standard Interface for which an121implementation is available to the public in source code form. A122"Major Component", in this context, means a major essential component123(kernel, window system, and so on) of the specific operating system124(if any) on which the executable work runs, or a compiler used to125produce the work, or an object code interpreter used to run it.126127The "Corresponding Source" for a work in object code form means all128the source code needed to generate, install, and (for an executable129work) run the object code and to modify the work, including scripts to130control those activities. However, it does not include the work's131System Libraries, or general-purpose tools or generally available free132programs which are used unmodified in performing those activities but133which are not part of the work. For example, Corresponding Source134includes interface definition files associated with source files for135the work, and the source code for shared libraries and dynamically136linked subprograms that the work is specifically designed to require,137such as by intimate data communication or control flow between those138subprograms and other parts of the work.139140The Corresponding Source need not include anything that users can141regenerate automatically from other parts of the Corresponding Source.142143The Corresponding Source for a work in source code form is that same144work.145146#### 2. Basic Permissions.147148All rights granted under this License are granted for the term of149copyright on the Program, and are irrevocable provided the stated150conditions are met. This License explicitly affirms your unlimited151permission to run the unmodified Program. The output from running a152covered work is covered by this License only if the output, given its153content, constitutes a covered work. This License acknowledges your154rights of fair use or other equivalent, as provided by copyright law.155156You may make, run and propagate covered works that you do not convey,157without conditions so long as your license otherwise remains in force.158You may convey covered works to others for the sole purpose of having159them make modifications exclusively for you, or provide you with160facilities for running those works, provided that you comply with the161terms of this License in conveying all material for which you do not162control copyright. Those thus making or running the covered works for163you must do so exclusively on your behalf, under your direction and164control, on terms that prohibit them from making any copies of your165copyrighted material outside their relationship with you.166167Conveying under any other circumstances is permitted solely under the168conditions stated below. Sublicensing is not allowed; section 10 makes169it unnecessary.170171#### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.172173No covered work shall be deemed part of an effective technological174measure under any applicable law fulfilling obligations under article17511 of the WIPO copyright treaty adopted on 20 December 1996, or176similar laws prohibiting or restricting circumvention of such177measures.178179When you convey a covered work, you waive any legal power to forbid180circumvention of technological measures to the extent such181circumvention is effected by exercising rights under this License with182respect to the covered work, and you disclaim any intention to limit183operation or modification of the work as a means of enforcing, against184the work's users, your or third parties' legal rights to forbid185circumvention of technological measures.186187#### 4. Conveying Verbatim Copies.188189You may convey verbatim copies of the Program's source code as you190receive it, in any medium, provided that you conspicuously and191appropriately publish on each copy an appropriate copyright notice;192keep intact all notices stating that this License and any193non-permissive terms added in accord with section 7 apply to the code;194keep intact all notices of the absence of any warranty; and give all195recipients a copy of this License along with the Program.196197You may charge any price or no price for each copy that you convey,198and you may offer support or warranty protection for a fee.199200#### 5. Conveying Modified Source Versions.201202You may convey a work based on the Program, or the modifications to203produce it from the Program, in the form of source code under the204terms of section 4, provided that you also meet all of these205conditions:206207- a) The work must carry prominent notices stating that you modified208 it, and giving a relevant date.209- b) The work must carry prominent notices stating that it is210 released under this License and any conditions added under211 section 7. This requirement modifies the requirement in section 4212 to "keep intact all notices".213- c) You must license the entire work, as a whole, under this214 License to anyone who comes into possession of a copy. This215 License will therefore apply, along with any applicable section 7216 additional terms, to the whole of the work, and all its parts,217 regardless of how they are packaged. This License gives no218 permission to license the work in any other way, but it does not219 invalidate such permission if you have separately received it.220- d) If the work has interactive user interfaces, each must display221 Appropriate Legal Notices; however, if the Program has interactive222 interfaces that do not display Appropriate Legal Notices, your223 work need not make them do so.224225A compilation of a covered work with other separate and independent226works, which are not by their nature extensions of the covered work,227and which are not combined with it such as to form a larger program,228in or on a volume of a storage or distribution medium, is called an229"aggregate" if the compilation and its resulting copyright are not230used to limit the access or legal rights of the compilation's users231beyond what the individual works permit. Inclusion of a covered work232in an aggregate does not cause this License to apply to the other233parts of the aggregate.234235#### 6. Conveying Non-Source Forms.236237You may convey a covered work in object code form under the terms of238sections 4 and 5, provided that you also convey the machine-readable239Corresponding Source under the terms of this License, in one of these240ways:241242- a) Convey the object code in, or embodied in, a physical product243 (including a physical distribution medium), accompanied by the244 Corresponding Source fixed on a durable physical medium245 customarily used for software interchange.246- b) Convey the object code in, or embodied in, a physical product247 (including a physical distribution medium), accompanied by a248 written offer, valid for at least three years and valid for as249 long as you offer spare parts or customer support for that product250 model, to give anyone who possesses the object code either (1) a251 copy of the Corresponding Source for all the software in the252 product that is covered by this License, on a durable physical253 medium customarily used for software interchange, for a price no254 more than your reasonable cost of physically performing this255 conveying of source, or (2) access to copy the Corresponding256 Source from a network server at no charge.257- 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.262- d) Convey the object code by offering access from a designated263 place (gratis or for a charge), and offer equivalent access to the264 Corresponding Source in the same way through the same place at no265 further charge. You need not require recipients to copy the266 Corresponding Source along with the object code. If the place to267 copy the object code is a network server, the Corresponding Source268 may be on a different server (operated by you or a third party)269 that supports equivalent copying facilities, provided you maintain270 clear directions next to the object code saying where to find the271 Corresponding Source. Regardless of what server hosts the272 Corresponding Source, you remain obligated to ensure that it is273 available for as long as needed to satisfy these requirements.274- e) Convey the object code using peer-to-peer transmission,275 provided you inform other peers where the object code and276 Corresponding Source of the work are being offered to the general277 public at no charge under subsection 6d.278279A separable portion of the object code, whose source code is excluded280from the Corresponding Source as a System Library, need not be281included in conveying the object code work.282283A "User Product" is either (1) a "consumer product", which means any284tangible personal property which is normally used for personal,285family, or household purposes, or (2) anything designed or sold for286incorporation into a dwelling. In determining whether a product is a287consumer product, doubtful cases shall be resolved in favor of288coverage. For a particular product received by a particular user,289"normally used" refers to a typical or common use of that class of290product, regardless of the status of the particular user or of the way291in which the particular user actually uses, or expects or is expected292to use, the product. A product is a consumer product regardless of293whether the product has substantial commercial, industrial or294non-consumer uses, unless such uses represent the only significant295mode of use of the product.296297"Installation Information" for a User Product means any methods,298procedures, authorization keys, or other information required to299install and execute modified versions of a covered work in that User300Product from a modified version of its Corresponding Source. The301information must suffice to ensure that the continued functioning of302the modified object code is in no case prevented or interfered with303solely because modification has been made.304305If you convey an object code work under this section in, or with, or306specifically for use in, a User Product, and the conveying occurs as307part of a transaction in which the right of possession and use of the308User Product is transferred to the recipient in perpetuity or for a309fixed term (regardless of how the transaction is characterized), the310Corresponding Source conveyed under this section must be accompanied311by the Installation Information. But this requirement does not apply312if neither you nor any third party retains the ability to install313modified object code on the User Product (for example, the work has314been installed in ROM).315316The requirement to provide Installation Information does not include a317requirement to continue to provide support service, warranty, or318updates for a work that has been modified or installed by the319recipient, or for the User Product in which it has been modified or320installed. Access to a network may be denied when the modification321itself materially and adversely affects the operation of the network322or violates the rules and protocols for communication across the323network.324325Corresponding 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.341342When 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.348349Notwithstanding any other provision of this License, for material you350add to a covered work, you may (if authorized by the copyright holders351of that 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; or355- b) Requiring preservation of specified reasonable legal notices or356 author attributions in that material or in the Appropriate Legal357 Notices displayed by works containing it; or358- c) Prohibiting misrepresentation of the origin of that material,359 or requiring that modified versions of such material be marked in360 reasonable ways as different from the original version; or361- d) Limiting the use for publicity purposes of names of licensors362 or authors of the material; or363- e) Declining to grant rights under trademark law for use of some364 trade names, trademarks, or service marks; or365- f) Requiring indemnification of licensors and authors of that366 material by anyone who conveys the material (or modified versions367 of it) with contractual assumptions of liability to the recipient,368 for any liability that these contractual assumptions directly369 impose on those licensors and authors.370371All other non-permissive additional terms are considered "further372restrictions" within the meaning of section 10. If the Program as you373received it, or any part of it, contains a notice stating that it is374governed by this License along with a term that is a further375restriction, you may remove that term. If a license document contains376a further restriction but permits relicensing or conveying under this377License, you may add to a covered work material governed by the terms378of that license document, provided that the further restriction does379not survive such relicensing or conveying.380381If you add terms to a covered work in accord with this section, you382must place, in the relevant source files, a statement of the383additional terms that apply to those files, or a notice indicating384where to find the applicable terms.385386Additional terms, permissive or non-permissive, may be stated in the387form of a separately written license, or stated as exceptions; the388above requirements apply either way.389390#### 8. Termination.391392You may not propagate or modify a covered work except as expressly393provided under this License. Any attempt otherwise to propagate or394modify it is void, and will automatically terminate your rights under395this License (including any patent licenses granted under the third396paragraph of section 11).397398However, if you cease all violation of this License, then your license399from a particular copyright holder is reinstated (a) provisionally,400unless and until the copyright holder explicitly and finally401terminates your license, and (b) permanently, if the copyright holder402fails to notify you of the violation by some reasonable means prior to40360 days after the cessation.404405Moreover, your license from a particular copyright holder is406reinstated permanently if the copyright holder notifies you of the407violation by some reasonable means, this is the first time you have408received notice of violation of this License (for any work) from that409copyright holder, and you cure the violation prior to 30 days after410your receipt of the notice.411412Termination of your rights under this section does not terminate the413licenses of parties who have received copies or rights from you under414this License. If your rights have been terminated and not permanently415reinstated, you do not qualify to receive new licenses for the same416material under section 10.417418#### 9. Acceptance Not Required for Having Copies.419420You are not required to accept this License in order to receive or run421a copy of the Program. Ancillary propagation of a covered work422occurring solely as a consequence of using peer-to-peer transmission423to receive a copy likewise does not require acceptance. However,424nothing other than this License grants you permission to propagate or425modify any covered work. These actions infringe copyright if you do426not accept this License. Therefore, by modifying or propagating a427covered work, you indicate your acceptance of this License to do so.428429#### 10. Automatic Licensing of Downstream Recipients.430431Each time you convey a covered work, the recipient automatically432receives a license from the original licensors, to run, modify and433propagate that work, subject to this License. You are not responsible434for enforcing compliance by third parties with this License.435436An "entity transaction" is a transaction transferring control of an437organization, or substantially all assets of one, or subdividing an438organization, or merging organizations. If propagation of a covered439work results from an entity transaction, each party to that440transaction who receives a copy of the work also receives whatever441licenses to the work the party's predecessor in interest had or could442give under the previous paragraph, plus a right to possession of the443Corresponding Source of the work from the predecessor in interest, if444the predecessor has it or can get it with reasonable efforts.445446You may not impose any further restrictions on the exercise of the447rights granted or affirmed under this License. For example, you may448not impose a license fee, royalty, or other charge for exercise of449rights granted under this License, and you may not initiate litigation450(including a cross-claim or counterclaim in a lawsuit) alleging that451any patent claim is infringed by making, using, selling, offering for452sale, or importing the Program or any portion of it.453454#### 11. Patents.455456A "contributor" is a copyright holder who authorizes use under this457License of the Program or a work on which the Program is based. The458work thus licensed is called the contributor's "contributor version".459460A contributor's "essential patent claims" are all patent claims owned461or controlled by the contributor, whether already acquired or462hereafter acquired, that would be infringed by some manner, permitted463by this License, of making, using, or selling its contributor version,464but do not include claims that would be infringed only as a465consequence of further modification of the contributor version. For466purposes of this definition, "control" includes the right to grant467patent sublicenses in a manner consistent with the requirements of468this License.469470Each contributor grants you a non-exclusive, worldwide, royalty-free471patent license under the contributor's essential patent claims, to472make, use, sell, offer for sale, import and otherwise run, modify and473propagate the contents of its contributor version.474475In the following three paragraphs, a "patent license" is any express476agreement or commitment, however denominated, not to enforce a patent477(such as an express permission to practice a patent or covenant not to478sue for patent infringement). To "grant" such a patent license to a479party means to make such an agreement or commitment not to enforce a480patent against the party.481482If you convey a covered work, knowingly relying on a patent license,483and the Corresponding Source of the work is not available for anyone484to copy, free of charge and under the terms of this License, through a485publicly available network server or other readily accessible means,486then you must either (1) cause the Corresponding Source to be so487available, or (2) arrange to deprive yourself of the benefit of the488patent license for this particular work, or (3) arrange, in a manner489consistent with the requirements of this License, to extend the patent490license to downstream recipients. "Knowingly relying" means you have491actual knowledge that, but for the patent license, your conveying the492covered work in a country, or your recipient's use of the covered work493in a country, would infringe one or more identifiable patents in that494country that you have reason to believe are valid.495496If, pursuant to or in connection with a single transaction or497arrangement, you convey, or propagate by procuring conveyance of, a498covered work, and grant a patent license to some of the parties499receiving the covered work authorizing them to use, propagate, modify500or convey a specific copy of the covered work, then the patent license501you grant is automatically extended to all recipients of the covered502work and works based on it.503504A patent license is "discriminatory" if it does not include within the505scope of its coverage, prohibits the exercise of, or is conditioned on506the non-exercise of one or more of the rights that are specifically507granted under this License. You may not convey a covered work if you508are a party to an arrangement with a third party that is in the509business of distributing software, under which you make payment to the510third party based on the extent of your activity of conveying the511work, and under which the third party grants, to any of the parties512who would receive the covered work from you, a discriminatory patent513license (a) in connection with copies of the covered work conveyed by514you (or copies made from those copies), or (b) primarily for and in515connection with specific products or compilations that contain the516covered work, unless you entered into that arrangement, or that patent517license was granted, prior to 28 March 2007.518519Nothing in this License shall be construed as excluding or limiting520any implied license or other defenses to infringement that may521otherwise be available to you under applicable patent law.522523#### 12. No Surrender of Others' Freedom.524525If conditions are imposed on you (whether by court order, agreement or526otherwise) that contradict the conditions of this License, they do not527excuse you from the conditions of this License. If you cannot convey a528covered work so as to satisfy simultaneously your obligations under529this License and any other pertinent obligations, then as a530consequence you may not convey it at all. For example, if you agree to531terms that obligate you to collect a royalty for further conveying532from those to whom you convey the Program, the only way you could533satisfy both those terms and this License would be to refrain entirely534from conveying the Program.535536#### 13. Remote Network Interaction; Use with the GNU General Public License.537538Notwithstanding any other provision of this License, if you modify the539Program, your modified version must prominently offer all users540interacting with it remotely through a computer network (if your541version supports such interaction) an opportunity to receive the542Corresponding Source of your version by providing access to the543Corresponding Source from a network server at no charge, through some544standard or customary means of facilitating copying of software. This545Corresponding Source shall include the Corresponding Source for any546work covered by version 3 of the GNU General Public License that is547incorporated pursuant to the following paragraph.548549Notwithstanding any other provision of this License, you have550permission to link or combine any covered work with a work licensed551under version 3 of the GNU General Public License into a single552combined work, and to convey the resulting work. The terms of this553License will continue to apply to the part which is the covered work,554but the work with which it is combined will remain governed by version5553 of the GNU General Public License.556557#### 14. Revised Versions of this License.558559The Free Software Foundation may publish revised and/or new versions560of the GNU Affero General Public License from time to time. Such new561versions will be similar in spirit to the present version, but may562differ in detail to address new problems or concerns.563564Each version is given a distinguishing version number. If the Program565specifies that a certain numbered version of the GNU Affero General566Public License "or any later version" applies to it, you have the567option of following the terms and conditions either of that numbered568version or of any later version published by the Free Software569Foundation. If the Program does not specify a version number of the570GNU Affero General Public License, you may choose any version ever571published by the Free Software Foundation.572573If the Program specifies that a proxy can decide which future versions574of the GNU Affero General Public License can be used, that proxy's575public statement of acceptance of a version permanently authorizes you576to choose that version for the Program.577578Later license versions may give you additional or different579permissions. However, no additional obligations are imposed on any580author or copyright holder as a result of your choosing to follow a581later version.582583#### 15. Disclaimer of Warranty.584585THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY586APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT587HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT588WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT589LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR590A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND591PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE592DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR593CORRECTION.594595#### 16. Limitation of Liability.596597IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING598WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR599CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,600INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES601ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT602NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR603LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM604TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER605PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.606607#### 17. Interpretation of Sections 15 and 16.608609If the disclaimer of warranty and limitation of liability provided610above cannot be given local legal effect according to their terms,611reviewing courts shall apply local law that most closely approximates612an absolute waiver of all civil liability in connection with the613Program, unless a warranty or assumption of liability accompanies a614copy of the Program in return for a fee.615616END OF TERMS AND CONDITIONS617618### How to Apply These Terms to Your New Programs619620If you develop a new program, and you want it to be of the greatest621possible use to the public, the best way to achieve this is to make it622free software which everyone can redistribute and change under these623terms.624625To do so, attach the following notices to the program. It is safest to626attach them to the start of each source file to most effectively state627the exclusion of warranty; and each file should have at least the628"copyright" line and a pointer to where the full notice is found.629630 <one line to give the program's name and a brief idea of what it does.>631 Copyright (C) <year> <name of author>632633 This program is free software: you can redistribute it and/or modify634 it under the terms of the GNU Affero General Public License as635 published by the Free Software Foundation, either version 3 of the636 License, or (at your option) any later version.637638 This program is distributed in the hope that it will be useful,639 but WITHOUT ANY WARRANTY; without even the implied warranty of640 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

For example, if your program is a web application, its652interface could display a "Source" link that leads users to an archive653of the code. There are many ways you could offer source, and different654solutions will be better for different programs; see section 13 for655the specific requirements.656657You should also get your employer (if you work as a programmer) or658school, if any, to sign a "copyright disclaimer" for the program, if659necessary.
