Appendix
modifying or distributing the Program
(or any work based on the Pr ogram),
you indicate your acceptance of this
License to do so, and all its terms and
conditions for copying, distributing or
modifying the Program or w orks based
on it.
6. Each time you redistribute the P rogram
(or any work based on the Pr ogram),
the recipient automatically receives
a license from the original licensor to
copy, distribute or modify the P rogram
subject to these terms and conditions.
Y ou may not impose any further
restrictions on the recipients’ exercise of
the rights granted herein. Y ou are not
responsible for enfor cing compliance
by third parties to this License.
7. If, as a consequence of a court
judgment or allegation of patent
infringement or for any other reason
(not limited to patent issues), condit ions
are imposed on you (whether by
court order, agr eement or otherwise)
that contradict the conditions of
this License, they do not excuse you
from the conditions of this License. If
you cannot distribute so as to satisfy
simultaneously your obligations under
this License and any other pertinent
obligations, then as a consequence you
may not distribute the Prog ram at all.
For example , if a patent license would
not permit royalty-free redistribution of
the Program b y all those who receive
copies directly or indirectly through
you, then the only way you could satisfy
both it and this License would be to
refrain entirely from distribution of the
Program.
If any portion of this section is held
invalid or unenforceable under an y
particular 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 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 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 r estricted in certain
countries either by patents or by
copyrighted interfaces, the original
copyright holder who places the
Program under this License ma y 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 F ree 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
dier in detail to address new problems
or concerns.
Each version is given a distinguishing
version number . If the Pr ogram species
a version number of this License which
applies to it and “ any later v ersion” , you
have the option of following the terms
and conditions either of that version
or of any later version published by
the Free Software F oundation. If the
Program does not specify a v ersion
number of this License, yo u may choose
any version ever published by the F ree
Software Foundation.
10. If you wish to incorporate parts of
the Program int o other free programs
whose distribution conditions are
dierent, write to the author to ask
for permission. F or software which
is copyrighted by the Fr ee Software
Foundation, write to the F ree 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.

How to Apply These T erms to Y our New
Programs
If you develop a new program, and you
want it to be of the greatest possible use to
the public, the best way to achieve this is to
make it free software which everyone can
redistribute and change under these terms.
T o do so, attach the f ollowing notices to the
program. It is safest to attach them to the
start of each source le to most eectively
convey the exclusion of warranty; and each
le should have at least the “ copyright ” line
and a pointer to where the full notice is
found.
<one line to give the program ’ s name
and an idea of what it does.>
