{\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.

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.

Also, for each author's protection and ours, we want to make certain that

everyone understands that there is no warranty for this Free Software. If

the software is modified by someone else and passed on, we want its

recipients to know that what they have is not the original, so that any

problems introduced by others will not reflect on the original authors'

reputations.

Finally, any Free program is threatened constantly by software patents.

We wish to avoid the danger that redistributors of a Free program will

individually obtain patent licenses, in effect making the program

proprietary. To prevent this, we have made it clear that any patent must

be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and

modification follow.

\item

This License applies to any program or other work which contains a notice

placed by the copyright holder saying it may be distributed under the

terms of this General Public License. The ``Program,'' below, refers to

any such program or work, and a ``work based on the Program'' means either

the Program or any derivative work under copyright law: that is to say, a

work containing the Program or a portion of it, either verbatim or with

modifications and/or translated into another language. (Hereinafter,

translation is included without limitation in the term ``modification.'')

Each licensee is addressed as ``you.''

Activities other than copying, distribution and modification are not
