GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation,
Inc.,

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.
Also, for each author's protection and ours, we want to
