{\bf\large Preamble}

\end{center}

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 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.
