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.

The 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

your program into proprietary programs. If your program
is a 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 Lesser General Public
