><P
> 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.
</P
><P
> 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.
</P
><P
> 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.
</P
><P
> 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.
</P
><P
> We protect your rights with two steps:
<P
></P
><OL
TYPE="1"
><LI
><P
> copyright the software, and
</P
></LI
><LI
><P
> offer you this license which gives you legal permission to
copy, distribute and/or modify the software.
</P
></LI
></OL
>
</P
><P
> 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.
</P
><P
> 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.
</P
><P
> The precise terms and conditions for copying, distribution and
modification follow.
