on excluding those countries, so that distribution 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 specifi es a version number of this License 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.
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 permission. For software which is
copyrighted by the Free Software 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 promo-
ting the sharing and reuse of software generally.
