Specifications

only way you could satisfy both it and this License would be to refrain en-
tirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any par-
ticular 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 sec-
tion has the sole purpose of protecting the integrity of the free software dis-
tribution system, which is implemented by public license practices. Many
people have made generous contributions to the wide range of software dis-
tributed through that system in reliance on consistent application of that sys-
tem; 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.
8. If the distribution and/or use of the Program is restricted in certain coun-
tries either by patents or by copyrighted interfaces, the original copyright
holder who places the Program under this License may add an explicit ge-
ographical distribution limitation excluding those countries, so that distri-
bution is permitted only in or among countries not thus excluded. In such
case, this License incorporates the limitation as if written in the body of this
License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will be
similar in spirit to the present version, but may differ in detail to address
new problems or concerns.
Each version is given a distinguishing version number. If the Program spec-
ifies a version number of this License which applies to it and “any later ver-
sion”, 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.
10. If you wish to incorporate parts of the Program into other free programs
whose distribution conditions are different, write to the author to ask for per-
mission. For software which is copyrighted by the Free Software Foundation,
write to the Free Software Foundation; we sometimes make exceptions for this.
