GNU GENERAL PUBLIC LICENSE

Version 3, 29 June 2007

Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not

allowed.

Preamble

The GNU General Public License is a free, copyleft license for software and other kinds of works.

The licenses for most software and other practical works are designed to take away your freedom to share and

change the works. By contrast, the GNU General Public License is 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 License 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.

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 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.
