   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) <year> <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) year 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. 

    signature of Ty Coon, 1 April 1989

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.
