Everyone is permitted to copy and distribute verbatim cop-
ies of this license document, but changing it is not allowed.
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 free-
dom 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 cov-
ered 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 free-
dom, not price. Our General Public Licenses are designed
to make sure that you have the freedom to distribute cop-
ies 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 sur-
render the rights. These restrictions translate to certain
responsibilities for you if you distribute copies of the soft-
ware, 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 origi-
nal authors' reputations.
Finally, any free program is threatened constantly by soft-
ware patents. We wish to avoid the danger that redistribu-
tors of a free program will individually obtain patent licens-
es, in effect making the program proprietary. To prevent
this, we have made it clear that any patent must be

GNU GENERAL PUBLIC LICENSE

Preamble
Version 2, June 1991
licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution
and modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION
AND MODIFICATION
0. 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 modi-
fications 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 modifica-
tion 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 (inde-
pendent of having been made by running the program).
Whether that is true depends on what the program
does.
1. You may copy and distribute verbatim copies of the
program's source code as you receive it, in any medium,
provided that you conspicuously and appropriately pub-
lish on each copy an appropriate copyright notice and
disclaimer of warranty; keep intact all the notices that
refer to this license and to the absence of any warranty;
and give any other recipients of the program a copy of
this license along with the Program.
You may charge a fee for the physical act of transferring
a copy, and you may at your option offer warranty pro-
tection in exchange for a fee.
2. You may modify your copy or copies of the program or
any portion of it, thus forming a work based on the
Program, and copy and distribute such modifications or
work under the terms of section 1 above, provided that
you also meet all of these conditions:
a) You must cause the modified files to carry prominent
notices stating that you changed the files and the
date of any change.
