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.

GNU GENERAL PUBLIC LICENSE
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.
