GNU GENERAL PUBLIC LICENSE

</h2>
Version 2, June 1991
<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 of this license document,
but changing it is not allowed.
<br />
<br />
<p>
Preamble</p>
<p>
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.
<br />
</p>
<p>
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.
<br />
</p>
<p>
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.
<br />
<br />
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.
<br />
<br />
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.
<br />
<br />
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.
<br />
<br />
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.
<br />
<br />
The precise terms and conditions for copying, distribution and modification follow.
<br />
</p>
<p>
GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
<br />
<br />
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".
<br />
<br />
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.
<br />
<br />
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.
<br />
<br />
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.
<br />
<br />
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 />
<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.
<br />
<br />
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.
<br />
<br />
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.
<br />
<br />
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 interchange; or,
<br />
b) Accompany it with a written offer, valid for at least three years, to give any
third party, for a charge no more than your cost of physically performing source
distribution, a complete machine-readable copy of the corresponding source code,
to be distributed under the terms of Sections 1 and 2 above on a medium customarily
used for software interchange; or,
<br />
c) Accompany it with the information you received as to the offer to distribute
corresponding source code. (This alternative is allowed only for noncommercial distribution
and only if you received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
<br />
<br />
The source code for a work means the preferred form of the work for making modifications
to it. For an executable work, complete source code means all the source code for
all modules it contains, plus any associated interface definition files, plus the
scripts used to control compilation and installation of the executable. However,
as a special exception, the source code distributed need not include anything that
is normally distributed (in either source or binary form) with the major components
(compiler, kernel, and so on) of the operating system on which the executable runs,
unless that component itself accompanies the executable.
<br />
<br />
If distribution of executable or object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the source code
from the same place counts as distribution of the source code, even though third
parties are not compelled to copy the source along with the object code.
<br />
<br />
4. You may not copy, modify, sublicense, or distribute the Program except as expressly
provided under this License. Any attempt otherwise to copy, modify, sublicense or
distribute the Program is void, and will automatically terminate your rights under
this License. However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such parties remain
in full compliance.
<br />
<br />
5. You are not required to accept this License, since you have not signed it. However,
nothing else grants you permission to modify or distribute the Program or its derivative
works. These actions are prohibited by law if you do not accept this License. Therefore,
by modifying or distributing the Program (or any work based on the Program), you
indicate your acceptance of this License to do so, and all its terms and conditions
for copying, distributing or modifying the Program or works based on it.
<br />
<br />
6. Each time you redistribute the Program (or any work based on the Program), the
recipient automatically receives a license from the original licensor to copy, distribute
or modify the Program subject to these terms and conditions. You may not impose
any further restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to this License.
<br />
<br />
7. If, as a consequence of a court judgment or allegation of patent infringement
or for any other reason (not limited to patent issues), conditions are imposed on
you (whether by court order, agreement or otherwise) that contradict the conditions
of this License, they do not excuse you from the conditions of this License. If
you cannot distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may not distribute
the Program at all. For example, if a patent license would not permit royalty-free
redistribution of the Program by all those who receive copies directly or indirectly
through you, then the only way you could satisfy both it and this License would
be to refrain entirely from distribution of the Program.
<br />
<br />
If any portion of this section is held invalid or unenforceable under any particular
circumstance, the balance of the section is intended to apply and the section as
a whole is intended to apply in other circumstances.
<br />
<br />
It is not the purpose of this section to induce you to infringe any patents or other
property right claims or to contest validity of any such claims; this section has
the sole purpose of protecting the integrity of the free software distribution system,
which is implemented by public license practices. Many people have made generous
contributions to the wide range of software distributed through that system in reliance
on consistent application of that system; it is up to the author/donor to decide
if he or she is willing to distribute software through any other system and a licensee
cannot impose that choice.
<br />
<br />
This section is intended to make thoroughly clear what is believed to be a consequence
of the rest of this License.
<br />
<br />
8. If the distribution and/or use of the Program is restricted in certain countries
either by patents or by copyrighted interfaces, the original copyright holder who
places the Program under this License may add an explicit geographical distribution
limitation excluding those countries, so that distribution is permitted only in
or among countries not thus excluded. In such case, this License incorporates the
limitation as if written in the body of this License.
<br />
<br />
9. The Free Software Foundation may publish revised and/or new versions of the General
Public License from time to time. Such new versions will be similar in spirit to
the present version, but may differ in detail to address new problems or concerns.
<br />
<br />
Each version is given a distinguishing version number. If the Program specifies
a version number of this License which applies to it and "any later version", you
have the option of following the terms and conditions either of that version or
of any later version published by the Free Software Foundation. If the Program does
not specify a version number of this License, you may choose any version ever published
by the Free Software Foundation.
<br />
<br />
10. If you wish to incorporate parts of the Program into other free programs whose
distribution conditions are different, write to the author to ask for permission.
For software which is copyrighted by the Free Software Foundation, write to the
Free Software Foundation; we sometimes make exceptions for this. Our decision will
be guided by the two goals of preserving the free status of all derivatives of our
free software and of promoting the sharing and reuse of software generally.
<br />
<br />
NO WARRANTY
<br />
<br />
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE
PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED
IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS"
WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED
TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.
THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD
THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR
OR CORRECTION.
<br />
<br />
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY
COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM
AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE
OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE
WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF
THE POSSIBILITY OF SUCH DAMAGES.
<br />
<br />
END OF TERMS AND CONDITIONS
<br />
<br />
How to Apply These Terms to Your New Programs
<br />
<br />
If you develop a new program, and you want it to be of the greatest possible use
to the public, the best way to achieve this is to make it free software which everyone
can redistribute and change under these terms.
<br />
<br />
To do so, attach the following notices to the program. It is safest to attach them
to the start of each source file to most effectively convey the exclusion of warranty;
and each file should have at least the "copyright" line and a pointer to where the
full notice is found. <br />
<br /></p>
<blockquote><p>
<one line to give the program's name and a brief idea of what it does.><br/>
Copyright (C) <year> <name of author>
</p>
<p>
This program is free software; you can redistribute it and/or modify it under the
terms of the GNU General Public License as published by the Free Software Foundation;
either version 2 of the License, or (at your option) any later version.
</p>
<p>
This program
is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without
even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
See the GNU General Public License for more details.
</p>
<p>
You should have received a
copy of the GNU General Public License along with this program; if not, write to
the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307
USA </p>
</blockquote>
<p>
Also add information on how to contact you by electronic and paper mail.
</p>
<p>
If
the program is interactive, make it output a short notice like this when it starts
in an interactive mode:
</p>
<blockquote>
Gnomovision version 69, Copyright (C) year name of author
<br />
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.<br />
This is
free software, and you are welcome to redistribute it under certain conditions;
type `show c' for details.
</blockquote>
<p>
The hypothetical commands `show w' and `show c' should
show the appropriate parts of the General Public License. Of course, the commands
you use may be called something other than `show w' and `show c'; they could even
be mouse-clicks or menu items
-whatever suits your program.
</p>
<p>
You should also get
your employer (if you work as a programmer) or your school, if any, to sign a "copyright
disclaimer" for the program, if necessary. Here is a sample; alter the names:
</p>
<blockquote>
<p>
Yoyodyne,
Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which
makes passes at compilers) written by James Hacker.</p>
<p>
<signature of Ty Coon>,
1 April 1989 <br />Ty Coon, President of Vice
</p>
</blockquote>
<p>
This General Public License does not permit
incorporating your program into proprietary programs. If your program is a subroutine
library, you may consider it more useful to permit linking proprietary applications
with the library. If this is what you want to do, use the GNU Library General Public
License instead of this License.
