want it, that you can change the software or use pieces of it in new

|
|
|
|
|
|
- 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 use the GNU GPL protect your rights with two steps:
|
|
|
-(1) assert copyright on the software, and (2) offer you this License
|
|
|
-giving you legal permission to copy, distribute and/or modify it.
|
|
|
-
|
|
|
- For the developers' and authors' protection, the GPL clearly explains
|
|
|
-that there is no warranty for this free software. For both users' and
|
|
|
-authors' sake, the GPL requires that modified versions be marked as
|
|
|
-changed, so that their problems will not be attributed erroneously to
|
|
|
-authors of previous versions.
|
|
|
-
|
|
|
- Some devices are designed to deny users access to install or run
|
|
|
-modified versions of the software inside them, although the manufacturer
|
|
|
-can do so. This is fundamentally incompatible with the aim of
|
|
|
-protecting users' freedom to change the software. The systematic
|
|
|
-pattern of such abuse occurs in the area of products for individuals to
|
|
|
-use, which is precisely where it is most unacceptable. Therefore, we
|
|
|
-have designed this version of the GPL to prohibit the practice for those
|
|
|
-products. If such problems arise substantially in other domains, we
|
|
|
-stand ready to extend this provision to those domains in future versions
|
|
|
-of the GPL, as needed to protect the freedom of users.
|
|
|
-
|
|
|
- Finally, every program is threatened constantly by software patents.
|
|
|
-States should not allow patents to restrict development and use of
|
|
|
-software on general-purpose computers, but in those that do, we wish to
|
|
|
-avoid the special danger that patents applied to a free program could
|
|
|
-make it effectively proprietary. To prevent this, the GPL assures that
|
|
|
-patents cannot be used to render the program non-free.
|
|
|
+ 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
|
