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 Lesser General Public License instead.)  You can
apply it to your programs, too.
