Everyone is permitted to copy and distribute ver-
batim copies of this license document, but chan-
ging 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 inten-
ded 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 free-
dom 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 restric-
tions that forbid anyone to deny you these rights
or to ask you to surrender the rights. These restric-
tions translate into 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 pro-
gram, 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) copy-
right the software, and (2) offer you this license
which gives you legal permission to copy, distri-
bute 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
118
what they have is not the original, so that any pro-
blems 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 individu-
ally 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 pre-
cise 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 copy-
right holder saying it may be distributed under
the terms of this General Public License. The "Pro-
gram", below, refers to any such program or work,
and a "work based on the Program" means either
the Program or any derivative work under copy-
right law: that is to say, a work containing the Pro-
gram or a portion of it, either verbatim or with
modifications and/or translated into another lan-
guage. (Hereinafter, translation is included wit-
hout limitation in the term "modification".) Each
licensee is addressed as "you".
Activities other than copying, distribution and
modification are not covered by this License; they
are outside its scope. The act of running the Pro-
gram 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). Whe-
ther 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 publish on each copy an appropri-
ate 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 trans-
ferring a copy, and you may, at your discretion,
offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Pro-
gram or any portion of it, thus forming a work
