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

incorporates the limitation as if written in the body of this
License.
9. The Free Software Foundation may publish revised and/

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.
