Freecom SILVER STORE 2-DRIVE NAS User Manual page 110

The hypothetical commands `show w' and `show c' should show the appropriate parts of
the General Public License. Of course, your program's commands might be different; for
a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school, if any, to
sign a "copyright disclaimer" for the program, if necessary. For more information on this,
and how to apply and follow the GNU GPL, see <http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating 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 License instead of this License. But first, please
read <http://www.gnu.org/philosophy/why-not-lgpl.html>.
