Preamble The GNU Affero General Public licensesis a free, copyleft licensesfor 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 licenseswhich 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 licensespermits 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
licensesis 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 licensesand 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 licensesare granted
for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This licensesexplicitly
affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this
licensesonly if the output, given its content, constitutes a covered work. This licensesacknowledges 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 licensesotherwise 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 licensesin 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
