GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
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 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.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
MODIFICATION
Activities other than copying, distribution and modification
are not covered by this License; they are outside its scope.
The act of running the Program is not restricted, and the
output from the Program is covered only if its contents
constitute a work based on the Program (independent of
having been made by running the Program). Whether that is
true depends on what the Program does.
You may charge a fee for the physical act of transferring a
copy, and you may at your option offer warranty protection
in exchange for a fee.
a) You must cause the modified files to carry prominent
notices stating that you changed the files and the date of any
change.
b) You must cause any work that you distribute or publish,
that in whole or in part contains or is derived from the
Program or any part thereof, to be licensed as a whole at no
charge to all third parties under the terms of this License.
c) If the modified program normally reads commands
interactively when run, you must cause it, when started
running for such interactive use in the most ordinary way, to
print or display an announcement including an appropriate
copyright notice and a notice that there is no warranty (or
else, saying that you provide a warranty) and that users may
redistribute the program under these conditions, and telling
the user how to view a copy of this License. (Exception: if the
Program itself is interactive but does not normally print such
an announcement, your work based on the Program is not
required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the
Program, and can be reasonably considered independent
and separate works in themselves, then this License, and its
terms, do not apply to those sections when you distribute
them as separate works. But when you distribute the same
sections as part of a whole which is a work based on the
Program, the distribution of the whole must be on the terms
of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part
regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or
contest your rights to work written entirely by you; rather,
the intent is to exercise the right to control the distribution of
derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on
the Program with the Program (or with a work based on the
