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.
