GNU GENERAL PUBLIC LICENSE

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, 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.
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.
The precise terms and conditions for copying, distribution and modification follow.
