                            PREAMBLE

The GNU General Public License is a free, copyleft license for software and
other kinds of works.

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.
