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.
