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

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
