impose any further restrictions on the recipients’ exercise of
the rights granted herein. You are not responsible for enforcing
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), conditions are imposed on you (whether by
court order, agreement 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 Program at all. For example, if a patent
license would not permit royalty-free redistribution of the
Program by 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 any 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 soware distribution system, which is implemented
by public license practices. Many people have made generous
contributions to the wide range of soware 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 soware through any other system and a licensee
cannot impose that choice. is 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. e Free Soware 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 Soware
Foundation. If the Program does not specify a version number
of this License, you may choose any version ever published by
the Free Soware 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 soware which
is copyrighted by the Free Soware Foundation, write to the
Free Soware 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 soware and of
promoting the sharing and reuse of soware generally.

How to Apply ese Terms to Your 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 soware which everyone can redistribute and
change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source le to most eectively
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 a brief idea of what
it does.
Copyright (C) <year><name of author>
is program is free soware; you can redistribute it and/or
modify it under the terms of the gnU general Public License
as published by the Free Soware Foundation; either version 2
of the License, or (at your option) any later version.
is program is distributed in the hope that it will be useful,
but WITHOUT AnY WArrAnTY; without even the implied
warranty of MErCHAnTABILITY or FITnESS FOr A
PArTICULAr PUrPOSE. See the gnU general Public
License for more details.
You should have received a copy of the gnU general Public
License along with this program; if not, write to the Free
Soware Foundation, Inc., 59 Temple Place, Suite 330, Boston,
MA 02111-1307 USA
Also add information on how to contact you by electronic and
paper mail.
If the program is interactive, make it output a short notice like
this when it starts in an interactive mode:
gnomovision version 69, Copyright (C) year name of author
gnomovision comes with ABSOLUTELY nO WArrAnTY; for
details type ‘show w’. is is free soware, and you are welcome
to redistribute it under certain conditions; type ‘show c’ for
details.
e hypothetical commands ‘show w’ and ‘show c’ should show
the appropriate parts of the general Public License. Of course,
the commands you use may be called something other than
‘show w’ and ‘show c’; they could even be mouse-clicks or menu
items--whatever suits your program.
You should also get your employer (if you work as a
programmer) or your school, if any, to sign a “copyright
disclaimer” for the program, if necessary. Here is a sample; alter
the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
program ‘gnomovision’ (which makes passes at compilers)
written by James Hacker.

is general Public License does not permit incorporating
you program into proprietary programs. If your program is
subroutine library, you may consider it more useful to permit
linking proprietary applications with the library. If this is what
you want to do,
use the gnU Library general Public License instead of this
License.
