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.+
