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
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 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 di󱐯er in detail to address new problems or
concerns.
Each version is given a distinguishing version number. If the
Program speci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 di󱐯erent,
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.
