GNU Affero General Public License
Version 3, 19 November 2007_ _Copyright © 2007 Free Software Foundation, Inc. <http://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) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
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) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
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:
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
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.
END OF TERMS AND CONDITIONS
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.
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 http://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 <http://www.gnu.org/licenses/>.

Everyone is permitted to copy and distribute verbatim copies

of this license document, but changing it is not allowed.

## Preamble
11
The GNU Affero General Public License is a free, copyleft license for
13
software and other kinds of works, specifically designed to ensure
14
cooperation with the community in the case of network server software.
15
The licenses for most software and other practical works are designed
17
to take away your freedom to share and change the works. By contrast,
18
our General Public Licenses are intended to guarantee your freedom to
19
share and change all versions of a program--to make sure it remains free
20
software for all its users.
21
When we speak of free software, we are referring to freedom, not
23
price. Our General Public Licenses are designed to make sure that you
24
have the freedom to distribute copies of free software (and charge for
25
them if you wish), that you receive source code or can get it if you
26
want it, that you can change the software or use pieces of it in new
27
free programs, and that you know you can do these things.
28
Developers that use our General Public Licenses protect your rights
30
with two steps: **(1)** assert copyright on the software, and **(2)** offer
31
you this License which gives you legal permission to copy, distribute
32
and/or modify the software.
33
A secondary benefit of defending all users' freedom is that
35
improvements made in alternate versions of the program, if they
36
receive widespread use, become available for other developers to
37
incorporate. Many developers of free software are heartened and
38
encouraged by the resulting cooperation. However, in the case of
39
software used on network servers, this result may fail to come about.
40
The GNU General Public License permits making a modified version and
41
letting the public access it on a server without ever releasing its
42
source code to the public.
43
The GNU Affero General Public License is designed specifically to
45
ensure that, in such cases, the modified source code becomes available
46
to the community. It requires the operator of a network server to
47
provide the source code of the modified version running there to the
48
users of that server. Therefore, public use of a modified version, on
49
a publicly accessible server, gives the public access to the source
50
code of the modified version.
51
An older license, called the Affero General Public License and
53
published by Affero, was designed to accomplish similar goals. This is
54
a different license, not a version of the Affero GPL, but Affero has
55
released a new version of the Affero GPL which permits relicensing under
56
this license.
57
The precise terms and conditions for copying, distribution and
59
modification follow.
60
## TERMS AND CONDITIONS
62
### 0. Definitions
64
“This License” refers to version 3 of the GNU Affero General Public License.
66
“Copyright” also means copyright-like laws that apply to other kinds of
68
works, such as semiconductor masks.
69
“The Program” refers to any copyrightable work licensed under this
71
License. Each licensee is addressed as “you”. “Licensees” and
72
“recipients” may be individuals or organizations.
73
To “modify” a work means to copy from or adapt all or part of the work
75
in a fashion requiring copyright permission, other than the making of an
76
exact copy. The resulting work is called a “modified version” of the
77
earlier work or a work “based on” the earlier work.
78
A “covered work” means either the unmodified Program or a work based
80
on the Program.
81
To “propagate” a work means to do anything with it that, without
83
permission, would make you directly or secondarily liable for
84
infringement under applicable copyright law, except executing it on a
85
computer or modifying a private copy. Propagation includes copying,
86
distribution (with or without modification), making available to the
87
public, and in some countries other activities as well.
88
To “convey” a work means any kind of propagation that enables other
90
parties to make or receive copies. Mere interaction with a user through
91
a computer network, with no transfer of a copy, is not conveying.
92
An interactive user interface displays “Appropriate Legal Notices”
94
to the extent that it includes a convenient and prominently visible
95
feature that **(1)** displays an appropriate copyright notice, and **(2)**
96
tells the user that there is no warranty for the work (except to the
97
extent that warranties are provided), that licensees may convey the
98
work under this License, and how to view a copy of this License. If
99
the interface presents a list of user commands or options, such as a
100
menu, a prominent item in the list meets this criterion.
101
### 1. Source Code
103
The “source code” for a work means the preferred form of the work
105
for making modifications to it. “Object code” means any non-source
106
form of a work.
107
A “Standard Interface” means an interface that either is an official
109
standard defined by a recognized standards body, or, in the case of
110
interfaces specified for a particular programming language, one that
111
is widely used among developers working in that language.
112
The “System Libraries” of an executable work include anything, other
114
than the work as a whole, that **(a)** is included in the normal form of
115
packaging a Major Component, but which is not part of that Major
116
Component, and **(b)** serves only to enable use of the work with that
117
Major Component, or to implement a Standard Interface for which an
118
implementation is available to the public in source code form. A
119
“Major Component”, in this context, means a major essential component
120
(kernel, window system, and so on) of the specific operating system
121
(if any) on which the executable work runs, or a compiler used to
122
produce the work, or an object code interpreter used to run it.
123
The “Corresponding Source” for a work in object code form means all
125
the source code needed to generate, install, and (for an executable
126
work) run the object code and to modify the work, including scripts to
127
control those activities. However, it does not include the work's
128
System Libraries, or general-purpose tools or generally available free
129
programs which are used unmodified in performing those activities but
130
which are not part of the work. For example, Corresponding Source
131
includes interface definition files associated with source files for
132
the work, and the source code for shared libraries and dynamically
133
linked subprograms that the work is specifically designed to require,
134
such as by intimate data communication or control flow between those
135
subprograms and other parts of the work.
136
The Corresponding Source need not include anything that users
138
can regenerate automatically from other parts of the Corresponding
139
Source.
140
The Corresponding Source for a work in source code form is that
142
same work.
143
### 2. Basic Permissions
145
All rights granted under this License are granted for the term of
147
copyright on the Program, and are irrevocable provided the stated
148
conditions are met. This License explicitly affirms your unlimited
149
permission to run the unmodified Program. The output from running a
150
covered work is covered by this License only if the output, given its
151
content, constitutes a covered work. This License acknowledges your
152
rights of fair use or other equivalent, as provided by copyright law.
153
You may make, run and propagate covered works that you do not
155
convey, without conditions so long as your license otherwise remains
156
in force. You may convey covered works to others for the sole purpose
157
of having them make modifications exclusively for you, or provide you
158
with facilities for running those works, provided that you comply with
159
the terms of this License in conveying all material for which you do
160
not control copyright. Those thus making or running the covered works
161
for you must do so exclusively on your behalf, under your direction
162
and control, on terms that prohibit them from making any copies of
163
your copyrighted material outside their relationship with you.
164
Conveying under any other circumstances is permitted solely under
166
the conditions stated below. Sublicensing is not allowed; section 10
167
makes it unnecessary.
168
### 3. Protecting Users' Legal Rights From Anti-Circumvention Law
170
No covered work shall be deemed part of an effective technological
172
measure under any applicable law fulfilling obligations under article
173
11 of the WIPO copyright treaty adopted on 20 December 1996, or
174
similar laws prohibiting or restricting circumvention of such
175
measures.
176
When you convey a covered work, you waive any legal power to forbid
178
circumvention of technological measures to the extent such circumvention
179
is effected by exercising rights under this License with respect to
180
the covered work, and you disclaim any intention to limit operation or
181
modification of the work as a means of enforcing, against the work's
182
users, your or third parties' legal rights to forbid circumvention of
183
technological measures.
184
### 4. Conveying Verbatim Copies
186
You may convey verbatim copies of the Program's source code as you
188
receive it, in any medium, provided that you conspicuously and
189
appropriately publish on each copy an appropriate copyright notice;
190
keep intact all notices stating that this License and any
191
non-permissive terms added in accord with section 7 apply to the code;
192
keep intact all notices of the absence of any warranty; and give all
193
recipients a copy of this License along with the Program.
194
You may charge any price or no price for each copy that you convey,
196
and you may offer support or warranty protection for a fee.
197
### 5. Conveying Modified Source Versions
199
You may convey a work based on the Program, or the modifications to
201
produce it from the Program, in the form of source code under the
202
terms of section 4, provided that you also meet all of these conditions:
203
* **a)** The work must carry prominent notices stating that you modified
205
it, and giving a relevant date.
206
* **b)** The work must carry prominent notices stating that it is
207
released under this License and any conditions added under section 7.
208
This requirement modifies the requirement in section 4 to
209
“keep intact all notices”.
210
* **c)** You must license the entire work, as a whole, under this
211
License to anyone who comes into possession of a copy. This
212
License will therefore apply, along with any applicable section 7
213
additional terms, to the whole of the work, and all its parts,
214
regardless of how they are packaged. This License gives no
215
permission to license the work in any other way, but it does not
216
invalidate such permission if you have separately received it.
217
* **d)** If the work has interactive user interfaces, each must display
218
Appropriate Legal Notices; however, if the Program has interactive
219
interfaces that do not display Appropriate Legal Notices, your
220
work need not make them do so.
221
A compilation of a covered work with other separate and independent
223
works, which are not by their nature extensions of the covered work,
224
and which are not combined with it such as to form a larger program,
225
in or on a volume of a storage or distribution medium, is called an
226
“aggregate” if the compilation and its resulting copyright are not
227
used to limit the access or legal rights of the compilation's users
228
beyond what the individual works permit. Inclusion of a covered work
229
in an aggregate does not cause this License to apply to the other
230
parts of the aggregate.
231
### 6. Conveying Non-Source Forms
233
You may convey a covered work in object code form under the terms
235
of sections 4 and 5, provided that you also convey the
236
machine-readable Corresponding Source under the terms of this License,
237
in one of these ways:
238
* **a)** Convey the object code in, or embodied in, a physical product
240
(including a physical distribution medium), accompanied by the
241
Corresponding Source fixed on a durable physical medium
242
customarily used for software interchange.
243
* **b)** Convey the object code in, or embodied in, a physical product
244
(including a physical distribution medium), accompanied by a
245
written offer, valid for at least three years and valid for as
246
long as you offer spare parts or customer support for that product
247
model, to give anyone who possesses the object code either **(1)** a
248
copy of the Corresponding Source for all the software in the
249
product that is covered by this License, on a durable physical
250
medium customarily used for software interchange, for a price no
251
more than your reasonable cost of physically performing this
252
conveying of source, or **(2)** access to copy the
253
Corresponding Source from a network server at no charge.
254
* **c)** Convey individual copies of the object code with a copy of the
255
written offer to provide the Corresponding Source. This
256
alternative is allowed only occasionally and noncommercially, and
257
only if you received the object code with such an offer, in accord
258
with subsection 6b.
259
* **d)** Convey the object code by offering access from a designated
260
place (gratis or for a charge), and offer equivalent access to the
261
Corresponding Source in the same way through the same place at no
262
further charge. You need not require recipients to copy the
263
Corresponding Source along with the object code. If the place to
264
copy the object code is a network server, the Corresponding Source
265
may be on a different server (operated by you or a third party)
266
that supports equivalent copying facilities, provided you maintain
267
clear directions next to the object code saying where to find the
268
Corresponding Source. Regardless of what server hosts the
269
Corresponding Source, you remain obligated to ensure that it is
270
available for as long as needed to satisfy these requirements.
271
* **e)** Convey the object code using peer-to-peer transmission, provided
272
you inform other peers where the object code and Corresponding
273
Source of the work are being offered to the general public at no
274
charge under subsection 6d.
275
A separable portion of the object code, whose source code is excluded
277
from the Corresponding Source as a System Library, need not be
278
included in conveying the object code work.
279
A “User Product” is either **(1)** a “consumer product”, which means any
281
tangible personal property which is normally used for personal, family,
282
or household purposes, or **(2)** anything designed or sold for incorporation
283
into a dwelling. In determining whether a product is a consumer product,
284
doubtful cases shall be resolved in favor of coverage. For a particular
285
product received by a particular user, “normally used” refers to a
286
typical or common use of that class of product, regardless of the status
287
of the particular user or of the way in which the particular user
288
actually uses, or expects or is expected to use, the product. A product
289
is a consumer product regardless of whether the product has substantial
290
commercial, industrial or non-consumer uses, unless such uses represent
291
the only significant mode of use of the product.
292
“Installation Information” for a User Product means any methods,
294
procedures, authorization keys, or other information required to install
295
and execute modified versions of a covered work in that User Product from
296
a modified version of its Corresponding Source. The information must
297
suffice to ensure that the continued functioning of the modified object
298
code is in no case prevented or interfered with solely because
299
modification has been made.
300
If you convey an object code work under this section in, or with, or
302
specifically for use in, a User Product, and the conveying occurs as
303
part of a transaction in which the right of possession and use of the
304
User Product is transferred to the recipient in perpetuity or for a
305
fixed term (regardless of how the transaction is characterized), the
306
Corresponding Source conveyed under this section must be accompanied
307
by the Installation Information. But this requirement does not apply
308
if neither you nor any third party retains the ability to install
309
modified object code on the User Product (for example, the work has
310
been installed in ROM).
311
The requirement to provide Installation Information does not include a
313
requirement to continue to provide support service, warranty, or updates
314
for a work that has been modified or installed by the recipient, or for
315
the User Product in which it has been modified or installed. Access to a
316
network may be denied when the modification itself materially and
317
adversely affects the operation of the network or violates the rules and
318
protocols for communication across the network.
319
Corresponding Source conveyed, and Installation Information provided,
321
in accord with this section must be in a format that is publicly
322
documented (and with an implementation available to the public in
323
source code form), and must require no special password or key for
324
unpacking, reading or copying.
325
### 7. Additional Terms
327
“Additional permissions” are terms that supplement the terms of this
329
License by making exceptions from one or more of its conditions.
330
Additional permissions that are applicable to the entire Program shall
331
be treated as though they were included in this License, to the extent
332
that they are valid under applicable law. If additional permissions
333
apply only to part of the Program, that part may be used separately
334
under those permissions, but the entire Program remains governed by
335
this License without regard to the additional permissions.
336
When you convey a copy of a covered work, you may at your option
338
remove any additional permissions from that copy, or from any part of
339
it. (Additional permissions may be written to require their own
340
removal in certain cases when you modify the work.) You may place
341
additional permissions on material, added by you to a covered work,
342
for which you have or can give appropriate copyright permission.
343
Notwithstanding any other provision of this License, for material you
345
add to a covered work, you may (if authorized by the copyright holders of
346
that material) supplement the terms of this License with terms:
347
* **a)** Disclaiming warranty or limiting liability differently from the
349
terms of sections 15 and 16 of this License; or
350
* **b)** Requiring preservation of specified reasonable legal notices or
351
author attributions in that material or in the Appropriate Legal
352
Notices displayed by works containing it; or
353
* **c)** Prohibiting misrepresentation of the origin of that material, or
354
requiring that modified versions of such material be marked in
355
reasonable ways as different from the original version; or
356
* **d)** Limiting the use for publicity purposes of names of licensors or
357
authors of the material; or
358
* **e)** Declining to grant rights under trademark law for use of some
359
trade names, trademarks, or service marks; or
360
* **f)** Requiring indemnification of licensors and authors of that
361
material by anyone who conveys the material (or modified versions of
362
it) with contractual assumptions of liability to the recipient, for
363
any liability that these contractual assumptions directly impose on
364
those licensors and authors.
365
All other non-permissive additional terms are considered “further
367
restrictions” within the meaning of section 10. If the Program as you
368
received it, or any part of it, contains a notice stating that it is
369
governed by this License along with a term that is a further
370
restriction, you may remove that term. If a license document contains
371
a further restriction but permits relicensing or conveying under this
372
License, you may add to a covered work material governed by the terms
373
of that license document, provided that the further restriction does
374
not survive such relicensing or conveying.
375
If you add terms to a covered work in accord with this section, you
377
must place, in the relevant source files, a statement of the
378
additional terms that apply to those files, or a notice indicating
379
where to find the applicable terms.
380
Additional terms, permissive or non-permissive, may be stated in the
382
form of a separately written license, or stated as exceptions;
383
the above requirements apply either way.
384
### 8. Termination
386
You may not propagate or modify a covered work except as expressly
388
provided under this License. Any attempt otherwise to propagate or
389
modify it is void, and will automatically terminate your rights under
390
this License (including any patent licenses granted under the third
391
paragraph of section 11).
392
However, if you cease all violation of this License, then your
394
license from a particular copyright holder is reinstated **(a)**
395
provisionally, unless and until the copyright holder explicitly and
396
finally terminates your license, and **(b)** permanently, if the copyright
397
holder fails to notify you of the violation by some reasonable means
398
prior to 60 days after the cessation.
399
Moreover, your license from a particular copyright holder is
401
reinstated permanently if the copyright holder notifies you of the
402
violation by some reasonable means, this is the first time you have
403
received notice of violation of this License (for any work) from that
404
copyright holder, and you cure the violation prior to 30 days after
405
your receipt of the notice.
406
Termination of your rights under this section does not terminate the
408
licenses of parties who have received copies or rights from you under
409
this License. If your rights have been terminated and not permanently
410
reinstated, you do not qualify to receive new licenses for the same
411
material under section 10.
412
### 9. Acceptance Not Required for Having Copies
414
You are not required to accept this License in order to receive or
416
run a copy of the Program. Ancillary propagation of a covered work
417
occurring solely as a consequence of using peer-to-peer transmission
418
to receive a copy likewise does not require acceptance. However,
419
nothing other than this License grants you permission to propagate or
420
modify any covered work. These actions infringe copyright if you do
421
not accept this License. Therefore, by modifying or propagating a
422
covered work, you indicate your acceptance of this License to do so.
423
### 10. Automatic Licensing of Downstream Recipients
425
Each time you convey a covered work, the recipient automatically
427
receives a license from the original licensors, to run, modify and
428
propagate that work, subject to this License. You are not responsible
429
for enforcing compliance by third parties with this License.
430
An “entity transaction” is a transaction transferring control of an
432
organization, or substantially all assets of one, or subdividing an
433
organization, or merging organizations. If propagation of a covered
434
work results from an entity transaction, each party to that
435
transaction who receives a copy of the work also receives whatever
436
licenses to the work the party's predecessor in interest had or could
437
give under the previous paragraph, plus a right to possession of the
438
Corresponding Source of the work from the predecessor in interest, if
439
the predecessor has it or can get it with reasonable efforts.
440
You may not impose any further restrictions on the exercise of the
442
rights granted or affirmed under this License. For example, you may
443
not impose a license fee, royalty, or other charge for exercise of
444
rights granted under this License, and you may not initiate litigation
445
(including a cross-claim or counterclaim in a lawsuit) alleging that
446
any patent claim is infringed by making, using, selling, offering for
447
sale, or importing the Program or any portion of it.
448
### 11. Patents
450
A “contributor” is a copyright holder who authorizes use under this
452
License of the Program or a work on which the Program is based. The
453
work thus licensed is called the contributor's “contributor version”.
454
A contributor's “essential patent claims” are all patent claims
456
owned or controlled by the contributor, whether already acquired or
457
hereafter acquired, that would be infringed by some manner, permitted
458
by this License, of making, using, or selling its contributor version,
459
but do not include claims that would be infringed only as a
460
consequence of further modification of the contributor version. For
461
purposes of this definition, “control” includes the right to grant
462
patent sublicenses in a manner consistent with the requirements of
463
this License.
464
Each contributor grants you a non-exclusive, worldwide, royalty-free
466
patent license under the contributor's essential patent claims, to
467
make, use, sell, offer for sale, import and otherwise run, modify and
468
propagate the contents of its contributor version.
469
In the following three paragraphs, a “patent license” is any express
471
agreement or commitment, however denominated, not to enforce a patent
472
(such as an express permission to practice a patent or covenant not to
473
sue for patent infringement). To “grant” such a patent license to a
474
party means to make such an agreement or commitment not to enforce a
475
patent against the party.
476
If you convey a covered work, knowingly relying on a patent license,
478
and the Corresponding Source of the work is not available for anyone
479
to copy, free of charge and under the terms of this License, through a
480
publicly available network server or other readily accessible means,
481
then you must either **(1)** cause the Corresponding Source to be so
482
available, or **(2)** arrange to deprive yourself of the benefit of the
483
patent license for this particular work, or **(3)** arrange, in a manner
484
consistent with the requirements of this License, to extend the patent
485
license to downstream recipients. “Knowingly relying” means you have
486
actual knowledge that, but for the patent license, your conveying the
487
covered work in a country, or your recipient's use of the covered work
488
in a country, would infringe one or more identifiable patents in that
489
country that you have reason to believe are valid.
490
If, pursuant to or in connection with a single transaction or
492
arrangement, you convey, or propagate by procuring conveyance of, a
493
covered work, and grant a patent license to some of the parties
494
receiving the covered work authorizing them to use, propagate, modify
495
or convey a specific copy of the covered work, then the patent license
496
you grant is automatically extended to all recipients of the covered
497
work and works based on it.
498
A patent license is “discriminatory” if it does not include within
500
the scope of its coverage, prohibits the exercise of, or is
501
conditioned on the non-exercise of one or more of the rights that are
502
specifically granted under this License. You may not convey a covered
503
work if you are a party to an arrangement with a third party that is
504
in the business of distributing software, under which you make payment
505
to the third party based on the extent of your activity of conveying
506
the work, and under which the third party grants, to any of the
507
parties who would receive the covered work from you, a discriminatory
508
patent license **(a)** in connection with copies of the covered work
509
conveyed by you (or copies made from those copies), or **(b)** primarily
510
for and in connection with specific products or compilations that
511
contain the covered work, unless you entered into that arrangement,
512
or that patent license was granted, prior to 28 March 2007.
513
Nothing in this License shall be construed as excluding or limiting
515
any implied license or other defenses to infringement that may
516
otherwise be available to you under applicable patent law.
517
### 12. No Surrender of Others' Freedom
519
If conditions are imposed on you (whether by court order, agreement or
521
otherwise) that contradict the conditions of this License, they do not
522
excuse you from the conditions of this License. If you cannot convey a
523
covered work so as to satisfy simultaneously your obligations under this
524
License and any other pertinent obligations, then as a consequence you may
525
not convey it at all. For example, if you agree to terms that obligate you
526
to collect a royalty for further conveying from those to whom you convey
527
the Program, the only way you could satisfy both those terms and this
528
License would be to refrain entirely from conveying the Program.
529
### 13. Remote Network Interaction; Use with the GNU General Public License
531
Notwithstanding any other provision of this License, if you modify the
533
Program, your modified version must prominently offer all users
534
interacting with it remotely through a computer network (if your version
535
supports such interaction) an opportunity to receive the Corresponding
536
Source of your version by providing access to the Corresponding Source
537
from a network server at no charge, through some standard or customary
538
means of facilitating copying of software. This Corresponding Source
539
shall include the Corresponding Source for any work covered by version 3
540
of the GNU General Public License that is incorporated pursuant to the
541
following paragraph.
542
Notwithstanding any other provision of this License, you have
544
permission to link or combine any covered work with a work licensed
545
under version 3 of the GNU General Public License into a single
546
combined work, and to convey the resulting work. The terms of this
547
License will continue to apply to the part which is the covered work,
548
but the work with which it is combined will remain governed by version
549
3 of the GNU General Public License.
550
### 14. Revised Versions of this License
552
The Free Software Foundation may publish revised and/or new versions of
554
the GNU Affero General Public License from time to time. Such new versions
555
will be similar in spirit to the present version, but may differ in detail to
556
address new problems or concerns.
557
Each version is given a distinguishing version number. If the
559
Program specifies that a certain numbered version of the GNU Affero General
560
Public License “or any later version” applies to it, you have the
561
option of following the terms and conditions either of that numbered
562
version or of any later version published by the Free Software
563
Foundation. If the Program does not specify a version number of the
564
GNU Affero General Public License, you may choose any version ever published
565
by the Free Software Foundation.
566
If the Program specifies that a proxy can decide which future
568
versions of the GNU Affero General Public License can be used, that proxy's
569
public statement of acceptance of a version permanently authorizes you
570
to choose that version for the Program.
571
Later license versions may give you additional or different
573
permissions. However, no additional obligations are imposed on any
574
author or copyright holder as a result of your choosing to follow a
575
later version.
576
### 15. Disclaimer of Warranty
578
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
580
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
581
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY
582
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
583
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
584
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
585
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
586
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
587
### 16. Limitation of Liability
589
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
591
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
592
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
593
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
594
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
595
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
596
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
597

SUCH DAMAGES.
599
### 17. Interpretation of Sections 15 and 16
601
If the disclaimer of warranty and limitation of liability provided
603
above cannot be given local legal effect according to their terms,
604
reviewing courts shall apply local law that most closely approximates
605
an absolute waiver of all civil liability in connection with the
606
Program, unless a warranty or assumption of liability accompanies a
607
copy of the Program in return for a fee.

## How to Apply These Terms to Your New Programs
612
If you develop a new program, and you want it to be of the greatest
614
possible use to the public, the best way to achieve this is to make it
615
free software which everyone can redistribute and change under these terms.
616
To do so, attach the following notices to the program. It is safest
618
to attach them to the start of each source file to most effectively
619
state the exclusion of warranty; and each file should have at least
620
the “copyright” line and a pointer to where the full notice is found.
621
<one line to give the program's name and a brief idea of what it does.>
623
Copyright (C) <year> <name of author>
624
This program is free software: you can redistribute it and/or modify
626
it under the terms of the GNU Affero General Public License as published by
627
the Free Software Foundation, either version 3 of the License, or
628
(at your option) any later version.
629
This program is distributed in the hope that it will be useful,
631
but WITHOUT ANY WARRANTY; without even the implied warranty of
632
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
633
GNU Affero General Public License for more details.
634
You should have received a copy of the GNU Affero General Public License
636
along with this program. If not, see <http://www.gnu.org/licenses/>.
637
Also add information on how to contact you by electronic and paper mail.
639
If your software can interact with users remotely through a computer
641
network, you should also make sure that it provides a way for users to
642
get its source. For example, if your program is a web application, its
643
interface could display a “Source” link that leads users to an archive
644
of the code. There are many ways you could offer source, and different
645
solutions will be better for different programs; see section 13 for the
646
specific requirements.
647
You should also get your employer (if you work as a programmer) or school,
649
if any, to sign a “copyright disclaimer” for the program, if necessary.
