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.
