GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007
Copyright © 2007 Free Software Foundation, Inc. <http://fsf.org/>
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, copyright 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 oth-
er 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 cop-
ies 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 ask-
ing you to surrender the rights. Therefore, you have certain responsibilities if you distrib-
ute 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, dis-
tribute 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.
