not accept this License. Therefore, by modifying or dis-
tributing the Program (or any work based on the Pro-
gram), you indicate your acceptance of this License to do
so, and all its terms and conditions for copying, distribut-
ing 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, dis-
tribute 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 lim-
ited 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 can-
not distribute so as to satisfy simultaneously your obliga-
tions under this License and any other pertinent obliga-
tions, 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 unenforce-
able 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 soft-
ware distribution system, which is implemented by pub-
lic 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 cop-
yrighted 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 a 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 ver-
sion 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 Foun-
96
dation, write to the Free Software Foundation; we some-
times 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 PRO-
GRAM "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 GEN-
ERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAM-
AGES 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 FAIL-
URE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY
HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAM-
AGES.
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.>
