[GNU GENERAL PUBLIC LICENSE]

Version 2, June 1991

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 ser vice 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.

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

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
