    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\xd5 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 Public 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
