Version 3, 19 November 2007
Copyright (C) 2007 Free Software Foundation, Inc.
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 to the greatest extent possible.
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. We, the Free Software Foundation, use the
GNU General Public Licenses for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
Developers that receive your program in Executable form may convert it
into source code, even if they do not have the source code of your program.
The GNU Affero General Public License specifically affirms the right of
users who interact with the program over a network to receive a copy of
the source code.
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.
To protect your rights, we need to prevent others from denying you these
rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that receive your program in Executable form may convert it
into source code, even if they do not have the source code of your program.
The GNU Affero General Public License specifically affirms the right of
users who interact with the program over a network to receive a copy of
the source code.
By "modified version" of the work, we mean either the work, or any
derivative work under copyright law: that is to say, a work containing
the program or a portion of it, either verbatim or with modifications
and/or translated into another language.
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
the work. "Executable code" means the source code, or a portion of it,
after it has been processed by a special program (compiler, interpreter,
etc.) so that it can be directly executed by a computer.
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 the Standard Interface of an operating system (if it is
a library that does that).
A "Major Component", in this context, means the kernel, compiler, or
other core component of a specific operating system (if any), or a
compiler or interpreter for a specific programming language.
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.
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.
"AGPL" also means the GNU Affero General Public License.
"AGPL Cover" means the GNU Affero General Public License, either
version 3 of the License, or (at your option) any later version.
A work is "covered" by this License if it is subject to AGPL Cover.
A work is "uncovered" if it is not covered by AGPL Cover.
If you develop a new work, and you want it to be free software, the
most effective way to do so is to state that it is subject to this
License. The following guidelines will help you do so.
a) You should put a notice like this near the beginning of each file:
This file is part of [name of your program].
[name of your 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,

b) You should also include a copy of the GNU Affero General Public
License in a file named "LICENSE" in the same directory as this
file.
c) If the program is interactive, you should make it output a short
notice like this when it starts in an interactive mode:

type `show w'.

The hypothetical commands `show w' and `show c' should show the
appropriate parts of the General Public License. Of course, the
commands you use may be different; for a GUI interface, you would
use an "about box".
d) 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, see

e) You should also include a copy of the GNU Affero General Public

How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be free software, the
most effective way to do so is to state that it is subject to this
License. The following guidelines will help you do so.
Attach these 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.
