Everyone is permitted to copy and distribute verba-
tim 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 con-
trast, 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 soft-
ware 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 trans-
late 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 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) 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 soft-
ware 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` reputa-
tions.
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, distri-
bution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DIS-
TRIBUTION 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 Pro-
gram 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 modifications
and/or translated into another language. (Hereinaf-
ter, translation is included without limitation in the
term "modification".) Each licensee is addressed as
"you".
Activities other than copying, distribution and modifi-
cation are not covered by this License; they are out-
side its scope. The act of running the Program is not
restricted, and the output from the Program is cov-
ered 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.
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 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 transfer-
ring a copy, and you may at your option offer war-
ranty 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 based
on the Program, and copy and distribute such modi-
fications or work under the terms of Section 1
above, provided that you also meet all of these con-
ditions:
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 com-
mands 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 copy-
right 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 announce-
ment.)
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 Program) on a volume of a stor-
