Preamble
The licenses for most software are designed to take away your freedom to 
share and change it.  By contrast, the GNU General Public License is 
intended to guarantee your freedom to share and change free software--
to make sure the software is free for all its users.  This General Public 
License applies to most of the Free Software Foundation's software and to 
any other program whose authors commit to using it.  (Some other Free 
Software Foundation software is covered by the GNU Library General Pub-
lic License instead.)  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 this service 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 make restrictions that forbid anyone to 
deny you these rights or to ask you to surrender the rights. These restric-
tions translate to certain responsibilities for you if you distribute copies of 
the software, or if you modify it.
