<P> GNU GENERAL PUBLIC LICENSE<BR>
Version 2, June 1991<BR>
<BR>
Copyright (C) 1989, 1991 Free Software Foundation, Inc.<BR>
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA<BR>
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>
along with the Program.<BR>
<BR>
You may charge a fee for the physical act of transferring a copy, and<BR>
you may at your option offer warranty protection in exchange for a fee.<BR>
<BR>
2. You may modify your copy or copies of the Program or any portion<BR>
of it, thus forming a work based on the Program, and copy and<BR>
distribute such modifications or work under the terms of Section 1<BR>
above, provided that you also meet all of these conditions:<BR>
<BR>
a) You must cause the modified files to carry prominent notices<BR>
stating that you changed the files and the date of any change.<BR>
<BR>
b) You must cause any work that you distribute or publish, that in<BR>
whole or in part contains or is derived from the Program or any<BR>
part thereof, to be licensed as a whole at no charge to all third<BR>
parties under the terms of this License.<BR>
<BR>
c) If the modified program normally reads commands interactively<BR>
when run, you must cause it, when started running for such<BR>
interactive use in the most ordinary way, to print or display an<BR>
announcement including an appropriate copyright notice and a<BR>
notice that there is no warranty (or else, saying that you provide<BR>
a warranty) and that users may redistribute the program under<BR>
these conditions, and telling the user how to view a copy of this<BR>
License. (Exception: if the Program itself is interactive but<BR>
does not normally print such an announcement, your work based on<BR>
the Program is not required to print an announcement.)<BR>
<BR>
These requirements apply to the modified work as a whole. If<BR>
identifiable sections of that work are not derived from the Program,<BR>
and can be reasonably considered independent and separate works in<BR>
themselves, then this License, and its terms, do not apply to those<BR>
sections when you distribute them as separate works. But when you<BR>
distribute the same sections as part of a whole which is a work based<BR>
on the Program, the distribution of the whole must be on the terms of<BR>
this License, whose permissions for other licensees extend to the<BR>
entire whole, and thus to each and every part regardless of who wrote it.<BR>
<BR>
Thus, it is not the intent of this section to claim rights or contest<BR>
your rights to work written entirely by you; rather, the intent is to<BR>
exercise the right to control the distribution of derivative or<BR>
collective works based on the Program.<BR>
<BR>
In addition, mere aggregation of another work not based on the Program<BR>
with the Program (or with a work based on the Program) on a volume of<BR>
a storage or distribution medium does not bring the other work under<BR>
the scope of this Lice
