GNU AFFERO GENERAL PUBLIC LICENSE

-

Version 3, 19 November 2007

- -

Copyright © 2007 Free Software Foundation, - Inc. <https://fsf.org/> -
- Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed.

- -

Preamble

- -

The GNU Affero General Public License is a free, copyleft license - for software and other kinds of works, specifically designed to ensure - cooperation with the community in the case of network server software.

- -

The licenses for most software and other practical works are - designed to take away your freedom to share and change the works. By - contrast, our General Public Licenses are intended to guarantee your - freedom to share and change all versions of a program--to make sure it - remains free software for all its users.

- -

When we speak of free software, we are referring to freedom, not - price. Our General Public Licenses are designed to make sure that you - have the freedom to distribute copies of free software (and charge for - them if you wish), that you receive source code or can get it if you - want it, that you can change the software or use pieces of it in new - free programs, and that you know you can do these things.

- -

Developers that use our General Public Licenses protect your rights - with two steps: (1) assert copyright on the software, and (2) offer - you this License which gives you legal permission to copy, distribute - and/or modify the software.

- -

A secondary benefit of defending all users' freedom is that - improvements made in alternate versions of the program, if they - receive widespread use, become available for other developers to - incorporate. Many developers of free software are heartened and - encouraged by the resulting cooperation. However, in the case of - software used on network servers, this result may fail to come about. - The GNU General Public License permits making a modified version and - letting the public access it on a server without ever releasing its - source code to the public.

- -

The GNU Affero General Public License is designed specifically to - ensure that, in such cases, the modified source code becomes available - to the community. It requires the operator of a network server to - provide the source code of the modified version running there to the - users of that server. Therefore, public use of a modified version, on - a publicly accessible server, gives the public access to the source - code of the modified version.

- -

An older license, called the Affero General Public License and - published by Affero, was designed to accomplish similar goals. This is - a different license, not a version of the Affero GPL, but Affero has - released a new version of the Affero GPL which permits relicensing under - this license.

- -

The precise terms and conditions for copying, distribution and - modification follow.

- -

TERMS AND CONDITIONS

- -

0. Definitions.

- -

"This License" refers to version 3 of the GNU Affero General Public - License.

- -

"Copyright" also means copyright-like laws that apply to other kinds - of works, such as semiconductor masks.

- -

"The Program" refers to any copyrightable work licensed under this - License. Each licensee is addressed as "you". "Licensees" and - "recipients" may be individuals or organizations.

- -

To "modify" a work means to copy from or adapt all or part of the work - in a fashion requiring copyright permission, other than the making of an - exact copy. The resulting work is called a "modified version" of the - earlier work or a work "based on" the earlier work.

- -

A "covered work" means either the unmodified Program or a work based - on the Program.

- -

To "propagate" a work means to do anything with it that, without - permission, would make you directly or secondarily liable for - infringement under applicable copyright law, except executing it on a - computer or modifying a private copy. Propagation includes copying, - distribution (with or without modification), making available to the - public, and in some countries other activities as well.

- -

To "convey" a work means any kind of propagation that enables other - parties to make or receive copies. Mere interaction with a user through - a computer network, with no transfer of a copy, is not conveying.

- -

An interactive user interface displays "Appropriate Legal Notices" - to the extent that it includes a convenient and prominently visible - feature that (1) displays an appropriate copyright notice, and (2) - tells the user that there is no warranty for the work (except to the - extent that warranties are provided), that licensees may convey the - work under this License, and how to view a copy of this License. If - the interface presents a list of user commands or options, such as a - menu, a prominent item in the list meets this criterion.

- -

1. Source Code.

- -

The "source code" for a work means the preferred form of the work - for making modifications to it. "Object code" means any non-source - form of a work.

- -

A "Standard Interface" means an interface that either is an official - standard defined by a recognized standards body, or, in the case of - interfaces specified for a particular programming language, one that - is widely used among developers working in that language.

- -

The "System Libraries" of an executable work include anything, other - than the work as a whole, that (a) is included in the normal form of - packaging a Major Component, but which is not part of that Major - Component, and (b) serves only to enable use of the work with that - Major Component, or to implement a Standard Interface for which an - implementation is available to the public in source code form. A - "Major Component", in this context, means a major essential component - (kernel, window system, and so on) of the specific operating system - (if any) on which the executable work runs, or a compiler used to - produce the work, or an object code interpreter used to run it.

- -

The "Corresponding Source" for a work in object code form means all - the source code needed to generate, install, and (for an executable - work) run the object code and to modify the work, including scripts to - control those activities. However, it does not include the work's - System Libraries, or general-purpose tools or generally available free - programs which are used unmodified in performing those activities but - which are not part of the work. For example, Corresponding Source - includes interface definition files associated with source files for - the work, and the source code for shared libraries and dynamically - linked subprograms that the work is specifically designed to require, - such as by intimate data communication or control flow between those - subprograms and other parts of the work.

- -

The Corresponding Source need not include anything that users - can regenerate automatically from other parts of the Corresponding - Source.

- -

The Corresponding Source for a work in source code form is that - same work.

- -

2. Basic Permissions.

- -

All rights granted under this License are granted for the term of - copyright on the Program, and are irrevocable provided the stated - conditions are met. This License explicitly affirms your unlimited - permission to run the unmodified Program. The output from running a - covered work is covered by this License only if the output, given its - content, constitutes a covered work. This License acknowledges your - rights of fair use or other equivalent, as provided by copyright law.

- -

You may make, run and propagate covered works that you do not - convey, without conditions so long as your license otherwise remains - in force. You may convey covered works to others for the sole purpose - of having them make modifications exclusively for you, or provide you - with facilities for running those works, provided that you comply with - the terms of this License in conveying all material for which you do - not control copyright. Those thus making or running the covered works - for you must do so exclusively on your behalf, under your direction - and control, on terms that prohibit them from making any copies of - your copyrighted material outside their relationship with you.

- -

Conveying under any other circumstances is permitted solely under - the conditions stated below. Sublicensing is not allowed; section 10 - makes it unnecessary.

- -

3. Protecting Users' Legal Rights From Anti-Circumvention Law.

- -

No covered work shall be deemed part of an effective technological - measure under any applicable law fulfilling obligations under article - 11 of the WIPO copyright treaty adopted on 20 December 1996, or - similar laws prohibiting or restricting circumvention of such - measures.

- -

When you convey a covered work, you waive any legal power to forbid - circumvention of technological measures to the extent such circumvention - is effected by exercising rights under this License with respect to - the covered work, and you disclaim any intention to limit operation or - modification of the work as a means of enforcing, against the work's - users, your or third parties' legal rights to forbid circumvention of - technological measures.

- -

4. Conveying Verbatim Copies.

- -

You may convey verbatim copies of the Program's source code as you - receive it, in any medium, provided that you conspicuously and - appropriately publish on each copy an appropriate copyright notice; - keep intact all notices stating that this License and any - non-permissive terms added in accord with section 7 apply to the code; - keep intact all notices of the absence of any warranty; and give all - recipients a copy of this License along with the Program.

- -

You may charge any price or no price for each copy that you convey, - and you may offer support or warranty protection for a fee.

- -

5. Conveying Modified Source Versions.

- -

You may convey a work based on the Program, or the modifications to - produce it from the Program, in the form of source code under the - terms of section 4, provided that you also meet all of these conditions:

- - - -

A compilation of a covered work with other separate and independent - works, which are not by their nature extensions of the covered work, - and which are not combined with it such as to form a larger program, - in or on a volume of a storage or distribution medium, is called an - "aggregate" if the compilation and its resulting copyright are not - used to limit the access or legal rights of the compilation's users - beyond what the individual works permit. Inclusion of a covered work - in an aggregate does not cause this License to apply to the other - parts of the aggregate.

- -

6. Conveying Non-Source Forms.

- -

You may convey a covered work in object code form under the terms - of sections 4 and 5, provided that you also convey the - machine-readable Corresponding Source under the terms of this License, - in one of these ways:

- - - -

A separable portion of the object code, whose source code is excluded - from the Corresponding Source as a System Library, need not be - included in conveying the object code work.

- -

A "User Product" is either (1) a "consumer product", which means any - tangible personal property which is normally used for personal, family, - or household purposes, or (2) anything designed or sold for incorporation - into a dwelling. In determining whether a product is a consumer product, - doubtful cases shall be resolved in favor of coverage. For a particular - product received by a particular user, "normally used" refers to a - typical or common use of that class of product, regardless of the status - of the particular user or of the way in which the particular user - actually uses, or expects or is expected to use, the product. A product - is a consumer product regardless of whether the product has substantial - commercial, industrial or non-consumer uses, unless such uses represent - the only significant mode of use of the product.

- -

"Installation Information" for a User Product means any methods, - procedures, authorization keys, or other information required to install - and execute modified versions of a covered work in that User Product from - a modified version of its Corresponding Source. The information must - suffice to ensure that the continued functioning of the modified object - code is in no case prevented or interfered with solely because - modification has been made.

- -

If you convey an object code work under this section in, or with, or - specifically for use in, a User Product, and the conveying occurs as - part of a transaction in which the right of possession and use of the - User Product is transferred to the recipient in perpetuity or for a - fixed term (regardless of how the transaction is characterized), the - Corresponding Source conveyed under this section must be accompanied - by the Installation Information. But this requirement does not apply - if neither you nor any third party retains the ability to install - modified object code on the User Product (for example, the work has - been installed in ROM).

- -

The requirement to provide Installation Information does not include a - requirement to continue to provide support service, warranty, or updates - for a work that has been modified or installed by the recipient, or for - the User Product in which it has been modified or installed. Access to a - network may be denied when the modification itself materially and - adversely affects the operation of the network or violates the rules and - protocols for communication across the network.

- -

Corresponding Source conveyed, and Installation Information provided, - in accord with this section must be in a format that is publicly - documented (and with an implementation available to the public in - source code form), and must require no special password or key for - unpacking, reading or copying.

- -

7. Additional Terms.

- -

"Additional permissions" are terms that supplement the terms of this - License by making exceptions from one or more of its conditions. - Additional permissions that are applicable to the entire Program shall - be treated as though they were included in this License, to the extent - that they are valid under applicable law. If additional permissions - apply only to part of the Program, that part may be used separately - under those permissions, but the entire Program remains governed by - this License without regard to the additional permissions.

- -

When you convey a copy of a covered work, you may at your option - remove any additional permissions from that copy, or from any part of - it. (Additional permissions may be written to require their own - removal in certain cases when you modify the work.) You may place - additional permissions on material, added by you to a covered work, - for which you have or can give appropriate copyright permission.

- -

Notwithstanding any other provision of this License, for material you - add to a covered work, you may (if authorized by the copyright holders of - that material) supplement the terms of this License with terms:

- - - -

All other non-permissive additional terms are considered "further - restrictions" within the meaning of section 10. If the Program as you - received it, or any part of it, contains a notice stating that it is - governed by this License along with a term that is a further restriction, - you may remove that term. If a license document contains a further - restriction but permits relicensing or conveying under this License, you - may add to a covered work material governed by the terms of that license - document, provided that the further restriction does not survive such - relicensing or conveying.

- -

If you add terms to a covered work in accord with this section, you - must place, in the relevant source files, a statement of the - additional terms that apply to those files, or a notice indicating - where to find the applicable terms.

- -

Additional terms, permissive or non-permissive, may be stated in the - form of a separately written license, or stated as exceptions; - the above requirements apply either way.

- -

8. Termination.

- -

You may not propagate or modify a covered work except as expressly - provided under this License. Any attempt otherwise to propagate or - modify it is void, and will automatically terminate your rights under - this License (including any patent licenses granted under the third - paragraph of section 11).

- -

However, if you cease all violation of this License, then your - license from a particular copyright holder is reinstated (a) - provisionally, unless and until the copyright holder explicitly and - finally terminates your license, and (b) permanently, if the copyright - holder fails to notify you of the violation by some reasonable means - prior to 60 days after the cessation.

- -

Moreover, your license from a particular copyright holder is - reinstated permanently if the copyright holder notifies you of the - violation by some reasonable means, this is the first time you have - received notice of violation of this License (for any work) from that - copyright holder, and you cure the violation prior to 30 days after - your receipt of the notice.

- -

Termination of your rights under this section does not terminate the - licenses of parties who have received copies or rights from you under - this License. If your rights have been terminated and not permanently - reinstated, you do not qualify to receive new licenses for the same - material under section 10.

- -

9. Acceptance Not Required for Having Copies.

- -

You are not required to accept this License in order to receive or - run a copy of the Program. Ancillary propagation of a covered work - occurring solely as a consequence of using peer-to-peer transmission - to receive a copy likewise does not require acceptance. However, - nothing other than this License grants you permission to propagate or - modify any covered work. These actions infringe copyright if you do - not accept this License. Therefore, by modifying or propagating a - covered work, you indicate your acceptance of this License to do so.

- -

10. Automatic Licensing of Downstream Recipients.

- -

Each time you convey a covered work, the recipient automatically - receives a license from the original licensors, to run, modify and - propagate that work, subject to this License. You are not responsible - for enforcing compliance by third parties with this License.

- -

An "entity transaction" is a transaction transferring control of an - organization, or substantially all assets of one, or subdividing an - organization, or merging organizations. If propagation of a covered - work results from an entity transaction, each party to that - transaction who receives a copy of the work also receives whatever - licenses to the work the party's predecessor in interest had or could - give under the previous paragraph, plus a right to possession of the - Corresponding Source of the work from the predecessor in interest, if - the predecessor has it or can get it with reasonable efforts.

- -

You may not impose any further restrictions on the exercise of the - rights granted or affirmed under this License. For example, you may - not impose a license fee, royalty, or other charge for exercise of - rights granted under this License, and you may not initiate litigation - (including a cross-claim or counterclaim in a lawsuit) alleging that - any patent claim is infringed by making, using, selling, offering for - sale, or importing the Program or any portion of it.

- -

11. Patents.

- -

A "contributor" is a copyright holder who authorizes use under this - License of the Program or a work on which the Program is based. The - work thus licensed is called the contributor's "contributor version".

- -

A contributor's "essential patent claims" are all patent claims - owned or controlled by the contributor, whether already acquired or - hereafter acquired, that would be infringed by some manner, permitted - by this License, of making, using, or selling its contributor version, - but do not include claims that would be infringed only as a - consequence of further modification of the contributor version. For - purposes of this definition, "control" includes the right to grant - patent sublicenses in a manner consistent with the requirements of - this License.

- -

Each contributor grants you a non-exclusive, worldwide, royalty-free - patent license under the contributor's essential patent claims, to - make, use, sell, offer for sale, import and otherwise run, modify and - propagate the contents of its contributor version.

- -

In the following three paragraphs, a "patent license" is any express - agreement or commitment, however denominated, not to enforce a patent - (such as an express permission to practice a patent or covenant not to - sue for patent infringement). To "grant" such a patent license to a - party means to make such an agreement or commitment not to enforce a - patent against the party.

- -

If you convey a covered work, knowingly relying on a patent license, - and the Corresponding Source of the work is not available for anyone - to copy, free of charge and under the terms of this License, through a - publicly available network server or other readily accessible means, - then you must either (1) cause the Corresponding Source to be so - available, or (2) arrange to deprive yourself of the benefit of the - patent license for this particular work, or (3) arrange, in a manner - consistent with the requirements of this License, to extend the patent - license to downstream recipients. "Knowingly relying" means you have - actual knowledge that, but for the patent license, your conveying the - covered work in a country, or your recipient's use of the covered work - in a country, would infringe one or more identifiable patents in that - country that you have reason to believe are valid.

- -

If, pursuant to or in connection with a single transaction or - arrangement, you convey, or propagate by procuring conveyance of, a - covered work, and grant a patent license to some of the parties - receiving the covered work authorizing them to use, propagate, modify - or convey a specific copy of the covered work, then the patent license - you grant is automatically extended to all recipients of the covered - work and works based on it.

- -

A patent license is "discriminatory" if it does not include within - the scope of its coverage, prohibits the exercise of, or is - conditioned on the non-exercise of one or more of the rights that are - specifically granted under this License. You may not convey a covered - work if you are a party to an arrangement with a third party that is - in the business of distributing software, under which you make payment - to the third party based on the extent of your activity of conveying - the work, and under which the third party grants, to any of the - parties who would receive the covered work from you, a discriminatory - patent license (a) in connection with copies of the covered work - conveyed by you (or copies made from those copies), or (b) primarily - for and in connection with specific products or compilations that - contain the covered work, unless you entered into that arrangement, - or that patent license was granted, prior to 28 March 2007.

- -

Nothing in this License shall be construed as excluding or limiting - any implied license or other defenses to infringement that may - otherwise be available to you under applicable patent law.

- -

12. No Surrender of Others' Freedom.

- -

If conditions are imposed on you (whether by court order, agreement or - otherwise) that contradict the conditions of this License, they do not - excuse you from the conditions of this License. If you cannot convey a - covered work so as to satisfy simultaneously your obligations under this - License and any other pertinent obligations, then as a consequence you may - not convey it at all. For example, if you agree to terms that obligate you - to collect a royalty for further conveying from those to whom you convey - the Program, the only way you could satisfy both those terms and this - License would be to refrain entirely from conveying the Program.

- -

13. Remote Network Interaction; Use with the GNU General Public License.

- -

Notwithstanding any other provision of this License, if you modify the - Program, your modified version must prominently offer all users - interacting with it remotely through a computer network (if your version - supports such interaction) an opportunity to receive the Corresponding - Source of your version by providing access to the Corresponding Source - from a network server at no charge, through some standard or customary - means of facilitating copying of software. This Corresponding Source - shall include the Corresponding Source for any work covered by version 3 - of the GNU General Public License that is incorporated pursuant to the - following paragraph.

- -

Notwithstanding any other provision of this License, you have permission - to link or combine any covered work with a work licensed under version 3 - of the GNU General Public License into a single combined work, and to - convey the resulting work. The terms of this License will continue to - apply to the part which is the covered work, but the work with which it is - combined will remain governed by version 3 of the GNU General Public - License.

- -

14. Revised Versions of this License.

- -

The Free Software Foundation may publish revised and/or new versions of - the GNU Affero General Public License from time to time. Such new - versions will be similar in spirit to the present version, but may differ - in detail to address new problems or concerns.

- -

Each version is given a distinguishing version number. If the - Program specifies that a certain numbered version of the GNU Affero - General Public License "or any later version" applies to it, you have - the option of following the terms and conditions either of that - numbered version or of any later version published by the Free - Software Foundation. If the Program does not specify a version number - of the GNU Affero General Public License, you may choose any version - ever published by the Free Software Foundation.

- -

If the Program specifies that a proxy can decide which future - versions of the GNU Affero General Public License can be used, that - proxy's public statement of acceptance of a version permanently - authorizes you to choose that version for the Program.

- -

Later license versions may give you additional or different - permissions. However, no additional obligations are imposed on any - author or copyright holder as a result of your choosing to follow a - later version.

- -

15. Disclaimer of Warranty.

- -

THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY - APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT - HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY - OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, - THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR - PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM - IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF - ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

- -

16. Limitation of Liability.

- -

IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING - WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS - THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY - GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE - USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF - DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD - PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), - EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF - SUCH DAMAGES.

How to Apply These Terms to Your New Programs

- -

If you develop a new program, and you want it to be of the greatest - possible use to the public, the best way to achieve this is to make it - free software which everyone can redistribute and change under these terms.

- -

To do so, attach the following notices to the program. It is safest - to attach them to the start of each source file to most effectively - state the exclusion of warranty; and each file should have at least - the "copyright" line and a pointer to where the full notice is found.

- - 
    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU Affero General Public License as
-    published by the Free Software Foundation, either version 3 of the
-    License, or (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU Affero General Public License for more details.
-
-    You should have received a copy of the GNU Affero General Public License
-    along with this program.  If not, see <https://www.gnu.org/licenses/>.
-
- -

Also add information on how to contact you by electronic and paper mail.

- -

If your software can interact with users remotely through a computer - network, you should also make sure that it provides a way for users to - get its source. For example, if your program is a web application, its - interface could display a "Source" link that leads users to an archive - of the code. There are many ways you could offer source, and different - solutions will be better for different programs; see section 13 for the - specific requirements.

- -

You should also get your employer (if you work as a programmer) or school, - if any, to sign a "copyright disclaimer" for the program, if necessary. - For more information on this, and how to apply and follow the GNU AGPL, see - <https://www.gnu.org/licenses/>.

Treebird

+
+
+

Treebird is a Pleroma frontend that is lightweight, efficient, and true to the web. It's written in C with FCGI making it simple and fast to work with and deploy. It is very tight to the philosophy of how the internet has always worked; Javascript provides extra sugar (or scripting) to improve the experience but not a requirement, while still being simple enough that anyone can use it.

+ +

Treebird was created in response to PleromaFE performance issues and ironically a lack of PleromaAPI backend support. Treebird resembles GNU Social in appearance by default, but keeps the familiarity that many are used to of PleromaFE.

+ +

Treebird was created by Nekobit, who created mastodont-c, a library that can communicate with Revolver's, Pleroma's, and Mastodon's REST APIs.

+ +

Treebird is licensed in AGPLv3, and mastodont-c is LGPLv3 licensed. Other licenses apply to libraries as well. View the AGPLv3 license here.

    GNU AFFERO GENERAL PUBLIC LICENSE

    +

    Version 3, 19 November 2007

    + +

    Copyright © 2007 Free Software Foundation, + Inc. <https://fsf.org/> +
    + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed.

    + +

    Preamble

    + +

    The GNU Affero General Public License is a free, copyleft license + for software and other kinds of works, specifically designed to ensure + cooperation with the community in the case of network server software.

    + +

    The licenses for most software and other practical works are + designed to take away your freedom to share and change the works. By + contrast, our General Public Licenses are intended to guarantee your + freedom to share and change all versions of a program--to make sure it + remains free software for all its users.

    + +

    When we speak of free software, we are referring to freedom, not + price. Our General Public Licenses are designed to make sure that you + have the freedom to distribute copies of free software (and charge for + them if you wish), that you receive source code or can get it if you + want it, that you can change the software or use pieces of it in new + free programs, and that you know you can do these things.

    + +

    Developers that use our General Public Licenses protect your rights + with two steps: (1) assert copyright on the software, and (2) offer + you this License which gives you legal permission to copy, distribute + and/or modify the software.

    + +

    A secondary benefit of defending all users' freedom is that + improvements made in alternate versions of the program, if they + receive widespread use, become available for other developers to + incorporate. Many developers of free software are heartened and + encouraged by the resulting cooperation. However, in the case of + software used on network servers, this result may fail to come about. + The GNU General Public License permits making a modified version and + letting the public access it on a server without ever releasing its + source code to the public.

    + +

    The GNU Affero General Public License is designed specifically to + ensure that, in such cases, the modified source code becomes available + to the community. It requires the operator of a network server to + provide the source code of the modified version running there to the + users of that server. Therefore, public use of a modified version, on + a publicly accessible server, gives the public access to the source + code of the modified version.

    + +

    An older license, called the Affero General Public License and + published by Affero, was designed to accomplish similar goals. This is + a different license, not a version of the Affero GPL, but Affero has + released a new version of the Affero GPL which permits relicensing under + this license.

    + +

    The precise terms and conditions for copying, distribution and + modification follow.

    + +

    TERMS AND CONDITIONS

    + +

    0. Definitions.

    + +

    "This License" refers to version 3 of the GNU Affero General Public + License.

    + +

    "Copyright" also means copyright-like laws that apply to other kinds + of works, such as semiconductor masks.

    + +

    "The Program" refers to any copyrightable work licensed under this + License. Each licensee is addressed as "you". "Licensees" and + "recipients" may be individuals or organizations.

    + +

    To "modify" a work means to copy from or adapt all or part of the work + in a fashion requiring copyright permission, other than the making of an + exact copy. The resulting work is called a "modified version" of the + earlier work or a work "based on" the earlier work.

    + +

    A "covered work" means either the unmodified Program or a work based + on the Program.

    + +

    To "propagate" a work means to do anything with it that, without + permission, would make you directly or secondarily liable for + infringement under applicable copyright law, except executing it on a + computer or modifying a private copy. Propagation includes copying, + distribution (with or without modification), making available to the + public, and in some countries other activities as well.

    + +

    To "convey" a work means any kind of propagation that enables other + parties to make or receive copies. Mere interaction with a user through + a computer network, with no transfer of a copy, is not conveying.

    + +

    An interactive user interface displays "Appropriate Legal Notices" + to the extent that it includes a convenient and prominently visible + feature that (1) displays an appropriate copyright notice, and (2) + tells the user that there is no warranty for the work (except to the + extent that warranties are provided), that licensees may convey the + work under this License, and how to view a copy of this License. If + the interface presents a list of user commands or options, such as a + menu, a prominent item in the list meets this criterion.

    + +

    1. Source Code.

    + +

    The "source code" for a work means the preferred form of the work + for making modifications to it. "Object code" means any non-source + form of a work.

    + +

    A "Standard Interface" means an interface that either is an official + standard defined by a recognized standards body, or, in the case of + interfaces specified for a particular programming language, one that + is widely used among developers working in that language.

    + +

    The "System Libraries" of an executable work include anything, other + than the work as a whole, that (a) is included in the normal form of + packaging a Major Component, but which is not part of that Major + Component, and (b) serves only to enable use of the work with that + Major Component, or to implement a Standard Interface for which an + implementation is available to the public in source code form. A + "Major Component", in this context, means a major essential component + (kernel, window system, and so on) of the specific operating system + (if any) on which the executable work runs, or a compiler used to + produce the work, or an object code interpreter used to run it.

    + +

    The "Corresponding Source" for a work in object code form means all + the source code needed to generate, install, and (for an executable + work) run the object code and to modify the work, including scripts to + control those activities. However, it does not include the work's + System Libraries, or general-purpose tools or generally available free + programs which are used unmodified in performing those activities but + which are not part of the work. For example, Corresponding Source + includes interface definition files associated with source files for + the work, and the source code for shared libraries and dynamically + linked subprograms that the work is specifically designed to require, + such as by intimate data communication or control flow between those + subprograms and other parts of the work.

    + +

    The Corresponding Source need not include anything that users + can regenerate automatically from other parts of the Corresponding + Source.

    + +

    The Corresponding Source for a work in source code form is that + same work.

    + +

    2. Basic Permissions.

    + +

    All rights granted under this License are granted for the term of + copyright on the Program, and are irrevocable provided the stated + conditions are met. This License explicitly affirms your unlimited + permission to run the unmodified Program. The output from running a + covered work is covered by this License only if the output, given its + content, constitutes a covered work. This License acknowledges your + rights of fair use or other equivalent, as provided by copyright law.

    + +

    You may make, run and propagate covered works that you do not + convey, without conditions so long as your license otherwise remains + in force. You may convey covered works to others for the sole purpose + of having them make modifications exclusively for you, or provide you + with facilities for running those works, provided that you comply with + the terms of this License in conveying all material for which you do + not control copyright. Those thus making or running the covered works + for you must do so exclusively on your behalf, under your direction + and control, on terms that prohibit them from making any copies of + your copyrighted material outside their relationship with you.

    + +

    Conveying under any other circumstances is permitted solely under + the conditions stated below. Sublicensing is not allowed; section 10 + makes it unnecessary.

    + +

    3. Protecting Users' Legal Rights From Anti-Circumvention Law.

    + +

    No covered work shall be deemed part of an effective technological + measure under any applicable law fulfilling obligations under article + 11 of the WIPO copyright treaty adopted on 20 December 1996, or + similar laws prohibiting or restricting circumvention of such + measures.

    + +

    When you convey a covered work, you waive any legal power to forbid + circumvention of technological measures to the extent such circumvention + is effected by exercising rights under this License with respect to + the covered work, and you disclaim any intention to limit operation or + modification of the work as a means of enforcing, against the work's + users, your or third parties' legal rights to forbid circumvention of + technological measures.

    + +

    4. Conveying Verbatim Copies.

    + +

    You may convey verbatim copies of the Program's source code as you + receive it, in any medium, provided that you conspicuously and + appropriately publish on each copy an appropriate copyright notice; + keep intact all notices stating that this License and any + non-permissive terms added in accord with section 7 apply to the code; + keep intact all notices of the absence of any warranty; and give all + recipients a copy of this License along with the Program.

    + +

    You may charge any price or no price for each copy that you convey, + and you may offer support or warranty protection for a fee.

    + +

    5. Conveying Modified Source Versions.

    + +

    You may convey a work based on the Program, or the modifications to + produce it from the Program, in the form of source code under the + terms of section 4, provided that you also meet all of these conditions:

    + + + +

    A compilation of a covered work with other separate and independent + works, which are not by their nature extensions of the covered work, + and which are not combined with it such as to form a larger program, + in or on a volume of a storage or distribution medium, is called an + "aggregate" if the compilation and its resulting copyright are not + used to limit the access or legal rights of the compilation's users + beyond what the individual works permit. Inclusion of a covered work + in an aggregate does not cause this License to apply to the other + parts of the aggregate.

    + +

    6. Conveying Non-Source Forms.

    + +

    You may convey a covered work in object code form under the terms + of sections 4 and 5, provided that you also convey the + machine-readable Corresponding Source under the terms of this License, + in one of these ways:

    + + + +

    A separable portion of the object code, whose source code is excluded + from the Corresponding Source as a System Library, need not be + included in conveying the object code work.

    + +

    A "User Product" is either (1) a "consumer product", which means any + tangible personal property which is normally used for personal, family, + or household purposes, or (2) anything designed or sold for incorporation + into a dwelling. In determining whether a product is a consumer product, + doubtful cases shall be resolved in favor of coverage. For a particular + product received by a particular user, "normally used" refers to a + typical or common use of that class of product, regardless of the status + of the particular user or of the way in which the particular user + actually uses, or expects or is expected to use, the product. A product + is a consumer product regardless of whether the product has substantial + commercial, industrial or non-consumer uses, unless such uses represent + the only significant mode of use of the product.

    + +

    "Installation Information" for a User Product means any methods, + procedures, authorization keys, or other information required to install + and execute modified versions of a covered work in that User Product from + a modified version of its Corresponding Source. The information must + suffice to ensure that the continued functioning of the modified object + code is in no case prevented or interfered with solely because + modification has been made.

    + +

    If you convey an object code work under this section in, or with, or + specifically for use in, a User Product, and the conveying occurs as + part of a transaction in which the right of possession and use of the + User Product is transferred to the recipient in perpetuity or for a + fixed term (regardless of how the transaction is characterized), the + Corresponding Source conveyed under this section must be accompanied + by the Installation Information. But this requirement does not apply + if neither you nor any third party retains the ability to install + modified object code on the User Product (for example, the work has + been installed in ROM).

    + +

    The requirement to provide Installation Information does not include a + requirement to continue to provide support service, warranty, or updates + for a work that has been modified or installed by the recipient, or for + the User Product in which it has been modified or installed. Access to a + network may be denied when the modification itself materially and + adversely affects the operation of the network or violates the rules and + protocols for communication across the network.

    + +

    Corresponding Source conveyed, and Installation Information provided, + in accord with this section must be in a format that is publicly + documented (and with an implementation available to the public in + source code form), and must require no special password or key for + unpacking, reading or copying.

    + +

    7. Additional Terms.

    + +

    "Additional permissions" are terms that supplement the terms of this + License by making exceptions from one or more of its conditions. + Additional permissions that are applicable to the entire Program shall + be treated as though they were included in this License, to the extent + that they are valid under applicable law. If additional permissions + apply only to part of the Program, that part may be used separately + under those permissions, but the entire Program remains governed by + this License without regard to the additional permissions.

    + +

    When you convey a copy of a covered work, you may at your option + remove any additional permissions from that copy, or from any part of + it. (Additional permissions may be written to require their own + removal in certain cases when you modify the work.) You may place + additional permissions on material, added by you to a covered work, + for which you have or can give appropriate copyright permission.

    + +

    Notwithstanding any other provision of this License, for material you + add to a covered work, you may (if authorized by the copyright holders of + that material) supplement the terms of this License with terms:

    + + + +

    All other non-permissive additional terms are considered "further + restrictions" within the meaning of section 10. If the Program as you + received it, or any part of it, contains a notice stating that it is + governed by this License along with a term that is a further restriction, + you may remove that term. If a license document contains a further + restriction but permits relicensing or conveying under this License, you + may add to a covered work material governed by the terms of that license + document, provided that the further restriction does not survive such + relicensing or conveying.

    + +

    If you add terms to a covered work in accord with this section, you + must place, in the relevant source files, a statement of the + additional terms that apply to those files, or a notice indicating + where to find the applicable terms.

    + +

    Additional terms, permissive or non-permissive, may be stated in the + form of a separately written license, or stated as exceptions; + the above requirements apply either way.

    + +

    8. Termination.

    + +

    You may not propagate or modify a covered work except as expressly + provided under this License. Any attempt otherwise to propagate or + modify it is void, and will automatically terminate your rights under + this License (including any patent licenses granted under the third + paragraph of section 11).

    + +

    However, if you cease all violation of this License, then your + license from a particular copyright holder is reinstated (a) + provisionally, unless and until the copyright holder explicitly and + finally terminates your license, and (b) permanently, if the copyright + holder fails to notify you of the violation by some reasonable means + prior to 60 days after the cessation.

    + +

    Moreover, your license from a particular copyright holder is + reinstated permanently if the copyright holder notifies you of the + violation by some reasonable means, this is the first time you have + received notice of violation of this License (for any work) from that + copyright holder, and you cure the violation prior to 30 days after + your receipt of the notice.

    + +

    Termination of your rights under this section does not terminate the + licenses of parties who have received copies or rights from you under + this License. If your rights have been terminated and not permanently + reinstated, you do not qualify to receive new licenses for the same + material under section 10.

    + +

    9. Acceptance Not Required for Having Copies.

    + +

    You are not required to accept this License in order to receive or + run a copy of the Program. Ancillary propagation of a covered work + occurring solely as a consequence of using peer-to-peer transmission + to receive a copy likewise does not require acceptance. However, + nothing other than this License grants you permission to propagate or + modify any covered work. These actions infringe copyright if you do + not accept this License. Therefore, by modifying or propagating a + covered work, you indicate your acceptance of this License to do so.

    + +

    10. Automatic Licensing of Downstream Recipients.

    + +

    Each time you convey a covered work, the recipient automatically + receives a license from the original licensors, to run, modify and + propagate that work, subject to this License. You are not responsible + for enforcing compliance by third parties with this License.

    + +

    An "entity transaction" is a transaction transferring control of an + organization, or substantially all assets of one, or subdividing an + organization, or merging organizations. If propagation of a covered + work results from an entity transaction, each party to that + transaction who receives a copy of the work also receives whatever + licenses to the work the party's predecessor in interest had or could + give under the previous paragraph, plus a right to possession of the + Corresponding Source of the work from the predecessor in interest, if + the predecessor has it or can get it with reasonable efforts.

    + +

    You may not impose any further restrictions on the exercise of the + rights granted or affirmed under this License. For example, you may + not impose a license fee, royalty, or other charge for exercise of + rights granted under this License, and you may not initiate litigation + (including a cross-claim or counterclaim in a lawsuit) alleging that + any patent claim is infringed by making, using, selling, offering for + sale, or importing the Program or any portion of it.

    + +

    11. Patents.

    + +

    A "contributor" is a copyright holder who authorizes use under this + License of the Program or a work on which the Program is based. The + work thus licensed is called the contributor's "contributor version".

    + +

    A contributor's "essential patent claims" are all patent claims + owned or controlled by the contributor, whether already acquired or + hereafter acquired, that would be infringed by some manner, permitted + by this License, of making, using, or selling its contributor version, + but do not include claims that would be infringed only as a + consequence of further modification of the contributor version. For + purposes of this definition, "control" includes the right to grant + patent sublicenses in a manner consistent with the requirements of + this License.

    + +

    Each contributor grants you a non-exclusive, worldwide, royalty-free + patent license under the contributor's essential patent claims, to + make, use, sell, offer for sale, import and otherwise run, modify and + propagate the contents of its contributor version.

    + +

    In the following three paragraphs, a "patent license" is any express + agreement or commitment, however denominated, not to enforce a patent + (such as an express permission to practice a patent or covenant not to + sue for patent infringement). To "grant" such a patent license to a + party means to make such an agreement or commitment not to enforce a + patent against the party.

    + +

    If you convey a covered work, knowingly relying on a patent license, + and the Corresponding Source of the work is not available for anyone + to copy, free of charge and under the terms of this License, through a + publicly available network server or other readily accessible means, + then you must either (1) cause the Corresponding Source to be so + available, or (2) arrange to deprive yourself of the benefit of the + patent license for this particular work, or (3) arrange, in a manner + consistent with the requirements of this License, to extend the patent + license to downstream recipients. "Knowingly relying" means you have + actual knowledge that, but for the patent license, your conveying the + covered work in a country, or your recipient's use of the covered work + in a country, would infringe one or more identifiable patents in that + country that you have reason to believe are valid.

    + +

    If, pursuant to or in connection with a single transaction or + arrangement, you convey, or propagate by procuring conveyance of, a + covered work, and grant a patent license to some of the parties + receiving the covered work authorizing them to use, propagate, modify + or convey a specific copy of the covered work, then the patent license + you grant is automatically extended to all recipients of the covered + work and works based on it.

    + +

    A patent license is "discriminatory" if it does not include within + the scope of its coverage, prohibits the exercise of, or is + conditioned on the non-exercise of one or more of the rights that are + specifically granted under this License. You may not convey a covered + work if you are a party to an arrangement with a third party that is + in the business of distributing software, under which you make payment + to the third party based on the extent of your activity of conveying + the work, and under which the third party grants, to any of the + parties who would receive the covered work from you, a discriminatory + patent license (a) in connection with copies of the covered work + conveyed by you (or copies made from those copies), or (b) primarily + for and in connection with specific products or compilations that + contain the covered work, unless you entered into that arrangement, + or that patent license was granted, prior to 28 March 2007.

    + +

    Nothing in this License shall be construed as excluding or limiting + any implied license or other defenses to infringement that may + otherwise be available to you under applicable patent law.

    + +

    12. No Surrender of Others' Freedom.

    + +

    If conditions are imposed on you (whether by court order, agreement or + otherwise) that contradict the conditions of this License, they do not + excuse you from the conditions of this License. If you cannot convey a + covered work so as to satisfy simultaneously your obligations under this + License and any other pertinent obligations, then as a consequence you may + not convey it at all. For example, if you agree to terms that obligate you + to collect a royalty for further conveying from those to whom you convey + the Program, the only way you could satisfy both those terms and this + License would be to refrain entirely from conveying the Program.

    + +

    13. Remote Network Interaction; Use with the GNU General Public License.

    + +

    Notwithstanding any other provision of this License, if you modify the + Program, your modified version must prominently offer all users + interacting with it remotely through a computer network (if your version + supports such interaction) an opportunity to receive the Corresponding + Source of your version by providing access to the Corresponding Source + from a network server at no charge, through some standard or customary + means of facilitating copying of software. This Corresponding Source + shall include the Corresponding Source for any work covered by version 3 + of the GNU General Public License that is incorporated pursuant to the + following paragraph.

    + +

    Notwithstanding any other provision of this License, you have permission + to link or combine any covered work with a work licensed under version 3 + of the GNU General Public License into a single combined work, and to + convey the resulting work. The terms of this License will continue to + apply to the part which is the covered work, but the work with which it is + combined will remain governed by version 3 of the GNU General Public + License.

    + +

    14. Revised Versions of this License.

    + +

    The Free Software Foundation may publish revised and/or new versions of + the GNU Affero General Public License from time to time. Such new + versions will be similar in spirit to the present version, but may differ + in detail to address new problems or concerns.

    + +

    Each version is given a distinguishing version number. If the + Program specifies that a certain numbered version of the GNU Affero + General Public License "or any later version" applies to it, you have + the option of following the terms and conditions either of that + numbered version or of any later version published by the Free + Software Foundation. If the Program does not specify a version number + of the GNU Affero General Public License, you may choose any version + ever published by the Free Software Foundation.

    + +

    If the Program specifies that a proxy can decide which future + versions of the GNU Affero General Public License can be used, that + proxy's public statement of acceptance of a version permanently + authorizes you to choose that version for the Program.

    + +

    Later license versions may give you additional or different + permissions. However, no additional obligations are imposed on any + author or copyright holder as a result of your choosing to follow a + later version.

    + +

    15. Disclaimer of Warranty.

    + +

    THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY + APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT + HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY + OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, + THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR + PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM + IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF + ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

    + +

    16. Limitation of Liability.

    + +

    IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING + WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS + THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY + GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE + USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF + DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD + PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), + EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF + SUCH DAMAGES.

    + +

    17. Interpretation of Sections 15 and 16.

    + +

    If the disclaimer of warranty and limitation of liability provided + above cannot be given local legal effect according to their terms, + reviewing courts shall apply local law that most closely approximates + an absolute waiver of all civil liability in connection with the + Program, unless a warranty or assumption of liability accompanies a + copy of the Program in return for a fee.

    How to Apply These Terms to Your New Programs

    + +

    If you develop a new program, and you want it to be of the greatest + possible use to the public, the best way to achieve this is to make it + free software which everyone can redistribute and change under these terms.

    + +

    To do so, attach the following notices to the program. It is safest + to attach them to the start of each source file to most effectively + state the exclusion of warranty; and each file should have at least + the "copyright" line and a pointer to where the full notice is found.

    + + 
        <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>

    + +

    Also add information on how to contact you by electronic and paper mail.

    + +

    If your software can interact with users remotely through a computer + network, you should also make sure that it provides a way for users to + get its source. For example, if your program is a web application, its + interface could display a "Source" link that leads users to an archive + of the code. There are many ways you could offer source, and different + solutions will be better for different programs; see section 13 for the + specific requirements.

    + +

    You should also get your employer (if you work as a programmer) or school, + if any, to sign a "copyright disclaimer" for the program, if necessary. + For more information on this, and how to apply and follow the GNU AGPL, see + <https://www.gnu.org/licenses/>.
