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 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 specifies a version number of this
License which applies to it and "any later version", you have the option of following the terms and condi-
tions 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 promoting the sharing and reuse of software generally.
