Everyone is permitted to copy and distribute verbatim copies<br>
of this license document, but changing it is not allowed.<br>
<br>
Preamble<br>
<br>
The licenses for most software are designed to take away your<br>
freedom to share and change it. By contrast, the GNU General Public<br>
License is intended to guarantee your freedom to share and change free<br>
software--to make sure the software is free for all its users. This<br>
General Public License applies to most of the Free Software<br>
Foundation's software and to any other program whose authors commit to<br>
using it. (Some other Free Software Foundation software is covered by<br>
the GNU Library General Public License instead.) You can apply it to<br>
your programs, too.<br>
<br>
When we speak of free software, we are referring to freedom, not<br>
price. Our General Public Licenses are designed to make sure that you<br>
have the freedom to distribute copies of free software (and charge for<br>
this service if you wish), that you receive source code or can get it<br>
if you want it, that you can change the software or use pieces of it<br>
in new free programs; and that you know you can do these things.<br>
<br>
To protect your rights, we need to make restrictions that forbid<br>
anyone to deny you these rights or to ask you to surrender the rights.<br>
These restrictions translate to certain responsibilities for you if you<br>
distribute copies of the software, or if you modify it.<br>
<br>
For example, if you distribute copies of such a program, whether<br>
gratis or for a fee, you must give the recipients all the rights that<br>
you have. You must make sure that they, too, receive or can get the<br>
source code. And you must show them these terms so they know their<br>
rights.<br>
<br>
We protect your rights with two steps: (1) copyright the software, and<br>
(2) offer you this license which gives you legal permission to copy,<br>
distribute and/or modify the software.<br>
<br>
Also, for each author's protection and ours, we want to make certain<br>
that everyone understands that there is no warranty for this free<br>
software. If the software is modified by someone else and passed on, we<br>
want its recipients to know that what they have is not the original, so<br>
that any problems introduced by others will not reflect on the original<br>
authors' reputations.<br>
<br>
Finally, any free program is threatened constantly by software<br>
patents. We wish to avoid the danger that redistributors of a free<br>
program will individually obtain patent licenses, in effect making the<br>
program proprietary. To prevent this, we have made it clear that any<br>
patent must be licensed for everyone's free use or not licensed at all.<br>
<br>
The precise terms and conditions for copying, distribution and<br>
modification follow.<br>
<br>
GNU GENERAL PUBLIC LICENSE<br>
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION<br>
<br>
0. This License applies to any program or other work which contains<br>
a notice placed by the copyright holder saying it may be distributed<br>
under the terms of this General Public License. The "Program", below,<br>
refers to any such program or work, and a "work based on the Program"<br>
means either the Program or any derivative work under copyright law:<br>
that is to say, a work containing the Program or a portion of it,<br>
either verbatim or with modifications and/or translated into another<br>
language. (Hereinafter, translation is included without limitation in<br>
the term "modification".) Each licensee is addressed as "you".<br>
<br>
Activities other than copying, distribution and modification are not<br>
covered by this License; they are outside its scope. The act of<br>
running the Program is not restricted, and the output from the Program<br>
is covered only if its contents constitute a work based on the<br>
Program (independent of having been made by running the Program).<br>
Whether that is true depends on what the Program does.<br>
<br>
1. You may copy and distribute verbatim copies of the Program's<br>
source code as you receive it, in any medium, provided that you<br>
conspicuously and appropriately publish on each copy an appropriate<br>
copyright notice and disclaimer of warranty; keep intact all the<br>
notices that refer to this License and to the absence of any warranty;<br>
and give any other recipients of the Program a copy of this License<br>
