GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Soware Foundaon, Inc.
51 Franklin Street, Fih Floor, Boston, MA 02110-1301, USA
Everyone is permied to copy and distribute verbam copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most soware 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 soware--to make sure the soware is free for all its users. This General Public License applies to most
of the Free Soware Foundaon’s soware and to any other program whose authors commit to using it. (Some other Free Soware Foundaon soware is
covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.
When we speak of free soware, 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 soware (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
so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 restricons that forbid anyone to deny you these rights or to ask you to surrender the rights. These restricons
translate to certain responsibilies for you if you distribute copies of the soware, or if you modify it.
For example, if you distribute copies of such a program, whether gras 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 soware, and (2) oer you this license which gives you legal permission to copy, distribute and/or
modify the soware.
Also, for each author’s protecon and ours, we want to make certain that everyone understands that there is no warranty for this free soware. If the
soware is modied 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 reect on the original authors’ reputaons.
Finally, any free program is threatened constantly by soware patents. We wish to avoid the danger that redistributors of a free program will individually
obtain patent licenses, in eect 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 condions for copying, distribuon and modicaon 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 noce 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
derivave work under copyright law: that is to say, a work containing the Program or a poron of it, either verbam or with modicaons and/or translated
into another language. (Hereinaer, translaon is included without limitaon in the term “modicaon”.) Each licensee is addressed as “you”.
Acvies other than copying, distribuon and modicaon 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 constute 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 verbam 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 noce and disclaimer of warranty; keep intact all the noces 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 opon oer warranty protecon in exchange for a fee.
2. You may modify your copy or copies of the Program or any poron of it, thus forming a work based on the Program, and copy and distribute such
modicaons or work under the terms of Secon 1 above, provided that you also meet all of these condions:
