GNU GENERAL PUBLIC

LICENSE

Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.

59 Temple Place, Suite 330, Boston, MA 02111-1307 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 Library

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

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 modifications 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

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.
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 transferring

a copy, and you may at your option offer warranty

protection 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.

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.)
