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 Lesser General Public License instead.)

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.

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.

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.

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 under the terms of Section 1 above.

3. You may copy and distribute the Program (or a work based on it)
in object code or executable form provided that you also do one of
the following:
a) Accompany it with the complete corresponding machine-readable
source code.
b) Accompany it with a written offer, valid for at least three years,
to give any third party a complete machine-readable copy of the
corresponding source code.
c) Accompany it with the information you received as to the offer
to distribute corresponding source code.

4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.

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.

6. Each time you redistribute the Program, the recipient
automatically receives a license from the original licensor.

7. If conditions are imposed on you that contradict the conditions
of this License, they do not excuse you from the conditions 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 may add an explicit geographical
distribution limitation.

9. The Free Software Foundation may publish revised and/or new
versions of the General Public License from time to time.

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.

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.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER BE LIABLE FOR DAMAGES ARISING OUT
OF THE USE OR INABILITY TO USE THE PROGRAM.
