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.

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. If you cannot distribute so as to
satisfy simultaneously your obligations under this License

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.

public license practices. Many people have made generous
