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 consi-
stent 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.
8. If the distribution and/or use of the Program is restricted in certain
countries either by patents or by copyrighted interfaces, the original
copyright holder who places the Program under this License may add an
explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus ex-
cluded. 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 versi-
ons 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
specifies a version number of this License which applies to it and „any
later version“, you have the option of following the terms and conditi-
ons 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 pro-
grams whose distribution conditions are different, write to the author to
ask for permission. For software which is copyrighted by the Free Soft-
ware Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and of
promoting the sharing and reuse of software generally.
