1                    GNU AFFERO GENERAL PUBLIC LICENSE2                       Version 3, 19 November 20073 4 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>5 Everyone is permitted to copy and distribute verbatim copies6 of this license document, but changing it is not allowed.7 8                            Preamble9 10  The GNU Affero General Public License is a free, copyleft license for11software and other kinds of works, specifically designed to ensure12cooperation with the community in the case of network server software.13 14  The licenses for most software and other practical works are designed15to take away your freedom to share and change the works.  By contrast,16our General Public Licenses are intended to guarantee your freedom to17share and change all versions of a program--to make sure it remains free18software for all its users.19 20  When we speak of free software, we are referring to freedom, not21price.  Our General Public Licenses are designed to make sure that you22have the freedom to distribute copies of free software (and charge for23them if you wish), that you receive source code or can get it if you24want it, that you can change the software or use pieces of it in new25free programs, and that you know you can do these things.26 27  Developers that use our General Public Licenses protect your rights28with two steps: (1) assert copyright on the software, and (2) offer29you this License which gives you legal permission to copy, distribute30and/or modify the software.31 32  A secondary benefit of defending all users' freedom is that33improvements made in alternate versions of the program, if they34receive widespread use, become available for other developers to35incorporate.  Many developers of free software are heartened and36encouraged by the resulting cooperation.  However, in the case of37software used on network servers, this result may fail to come about.38The GNU General Public License permits making a modified version and39letting the public access it on a server without ever releasing its40source code to the public.41 42  The GNU Affero General Public License is designed specifically to43ensure that, in such cases, the modified source code becomes available44to the community.  It requires the operator of a network server to45provide the source code of the modified version running there to the46users of that server.  Therefore, public use of a modified version, on47a publicly accessible server, gives the public access to the source48code of the modified version.49 50  An older license, called the Affero General Public License and51published by Affero, was designed to accomplish similar goals.  This is52a different license, not a version of the Affero GPL, but Affero has53released a new version of the Affero GPL which permits relicensing under54this license.55 56  The precise terms and conditions for copying, distribution and57modification follow.58 59                       TERMS AND CONDITIONS60 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 of66works, such as semiconductor masks.67 68  "The Program" refers to any copyrightable work licensed under this69License.  Each licensee is addressed as "you".  "Licensees" and70"recipients" may be individuals or organizations.71 72  To "modify" a work means to copy from or adapt all or part of the work73in a fashion requiring copyright permission, other than the making of an74exact copy.  The resulting work is called a "modified version" of the75earlier work or a work "based on" the earlier work.76 77  A "covered work" means either the unmodified Program or a work based78on the Program.79 80  To "propagate" a work means to do anything with it that, without81permission, would make you directly or secondarily liable for82infringement under applicable copyright law, except executing it on a83computer or modifying a private copy.  Propagation includes copying,84distribution (with or without modification), making available to the85public, and in some countries other activities as well.86 87  To "convey" a work means any kind of propagation that enables other88parties to make or receive copies.  Mere interaction with a user through89a 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 visible93feature that (1) displays an appropriate copyright notice, and (2)94tells the user that there is no warranty for the work (except to the95extent that warranties are provided), that licensees may convey the96work under this License, and how to view a copy of this License.  If97the interface presents a list of user commands or options, such as a98menu, a prominent item in the list meets this criterion.99 100  1. Source Code.101 102  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.105 106  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.110 111  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.121 122  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.134 135  The Corresponding Source need not include anything that users136can regenerate automatically from other parts of the Corresponding137Source.138 139  The Corresponding Source for a work in source code form is that140same work.141 142  2. Basic Permissions.143 144  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.151 152  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.162 163  Conveying under any other circumstances is permitted solely under164the conditions stated below.  Sublicensing is not allowed; section 10165makes it unnecessary.166 167  3. Protecting Users' Legal Rights From Anti-Circumvention Law.168 169  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.174 175  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.182 183  4. Conveying Verbatim Copies.184 185  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.192 193  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.195 196  5. Conveying Modified Source Versions.197 198  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:201 202    a) The work must carry prominent notices stating that you modified203    it, and giving a relevant date.204 205    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".209 210    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.217 218    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.222 223  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.232 233  6. Conveying Non-Source Forms.234 235  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:239 240    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.244 245    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.256 257    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.262 263    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.275 276    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.280 281  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.284 285  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.297 298  "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.305 306  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).316 317  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.324 325  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.330 331  7. Additional Terms.332 333  "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.341 342  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.348 349  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:352 353    a) Disclaiming warranty or limiting liability differently from the354    terms of sections 15 and 16 of this License; or355 356    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; or359 360    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; or363 364    d) Limiting the use for publicity purposes of names of licensors or365    authors of the material; or366 367    e) Declining to grant rights under trademark law for use of some368    trade names, trademarks, or service marks; or369 370    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.375 376  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.385 386  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.390 391  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.394 395  8. Termination.396 397  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).402 403  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.409 410  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.416 417  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 10.422 423  9. Acceptance Not Required for Having Copies.424 425  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.433 434  10. Automatic Licensing of Downstream Recipients.435 436  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.440 441  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.450 451  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.458 459  11. Patents.460 461  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".464 465  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.474 475  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.479 480  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.486 487  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.500 501  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.508 509  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 2007.523 524  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.527 528  12. No Surrender of Others' Freedom.529 530  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.539 540  13. Remote Network Interaction; Use with the GNU General Public License.541 542  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.552 553  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.560 561  14. Revised Versions of this License.562 563  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.567 568  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.576 577  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.581 582  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.586 587  15.

Interpretation of Sections 15 and 16.611 612  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.618 619                     END OF TERMS AND CONDITIONS620 621            How to Apply These Terms to Your New Programs622 623  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.626 627  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.631 632    <one line to give the program's name and a brief idea of what it does.>633    Copyright (C) <year>  <name of author>634 635    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.639 640    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.657 658  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<https://www.gnu.org/licenses/>.662
