Everyone is permitted to copy and distribute verbatim 
copies of this license document, but changing it is not 
allowed.

	 	Preamble

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.

	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 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.

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.

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:
a) You must cause the modified files to carry 
prominent notices stating that you changed the files 
and the date of any change.
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.
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.)
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.

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:
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,
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,
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.)
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. 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.

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.

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.

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.

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. 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. 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. This section 
is intended to make thoroughly clear what is believed 
to be a consequence of the rest of this License.

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.

 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. 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.

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.

	NO WARRANTY

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.

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 END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

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.
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. <one 
line to give the program's name and a brief idea of 
what it does.> Copyright (C) 19yy <name of author> 
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.
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. 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.
Also add information on how to contact you by 
electronic and paper mail. If the program is interactive, 
make it output a short notice like this when it starts in 
an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of 
author. Gnomovision comes with ABSOLUTELY NO 
WARRANTY; for details type `show w'. This is free 
software, and you are welcome to redistribute it under 
certain conditions; type `show c' for details. 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. 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: Yoyodyne, Inc., hereby disclaims all copyright 
interest in the program `Gnomovision' (which makes 
passes at compilers) written by James Hacker.

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.
