<P align=center><BIG>GNU GENERAL PUBLIC LICENSE</BIG>
<P align=center>Version 2, June 1991<BR>Copyright (C) 1989, 1991 Free
Software Foundation, Inc.<BR>675 Mass Ave, Cambridge, MA 02139, USA<BR>
<P align=left>Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
<P>
<P><BIG>Preamble</BIG><BR>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.
<P>
<P>GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING,
DISTRIBUTION AND MODIFICATION
<P>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.
<P>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.
<P>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:<BR>a) You must cause the modified
files to carry prominent notices stating that you changed the files and
the date of any change.<BR>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.<BR>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.)<BR>These requirements apply to the modified
work as a whole. If identifiable sections of that work are not derived
from the Program, and can be reasonably considered independent and
separate works in themselves, then this License, and its terms, do not
apply to those sections when you distribute them as separate works. But
when you distribute the same sections as part of a whole which is a work
based on the Program, the distribution of the whole must be on the terms
of this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise
the right to control the distribution of derivative or collective works
based on the Program. In addition, mere aggregation of another work not
based on the Program with the Program (or with a work based on the
Program) on a volume of a storage or distribution medium does not bring
the other work under the scope of this License.
<P>3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the
following:<BR>a) Accompany it with the complete corresponding
machine-readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software
