Everyone is permitted to copy and distribute verbatim
copies
of this license document, but changing it is not
allowed.
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.
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 restrictions
translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a
program, whether gratis or for a fee, you must give
the recipients all the rights that you have. 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.
We protect your rights with two steps: (1) copyright
the software, and (2) offer you this license which
gives you legal permission to copy, distribute and/or
modify the software.
