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 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 promoting the
sharing and reuse of software generally.

How to Apply These 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 software 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 file to most effectively
convey the exclusion of warranty ; and each file 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.

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

Preamble
The GNU General Public License is a free, copyleft license
for software and other kinds of works. The licenses for
most software and other practical works are designed to
take away your freedom to share and change the works.
By contrast, the GNU General Public License is intended to
guarantee your freedom to share and change all versions of
a program--to make sure it remains free software for all its
users.
We, the Free Software Foundation, use the GNU General
Public License for most of our software; it applies also to any
other work released this way by its authors.
You can apply it to your programs, too. When we speak of
free software, we are referring to freedom, not price. Our
General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and
charge for them if you wish), that you receive source code or
can get it if you want it, that you can change the software or
use pieces of it in new free programs, and that you know you
can do these things.
