+Be sure that man pages include a copyright statement and free
+license. The simple all-permissive license is appropriate for simple
+man pages:
+
+@example
+Copying and distribution of this file, with or without modification,
+are permitted in any medium without royalty provided the copyright
+notice and this notice are preserved.
+@end example
+
+For long man pages, with enough explanation and documentation that
+they can be considered true manuals, use the GFDL (@pxref{License for
+Manuals}).
+
+Finally, the GNU help2man program
+(@uref{http://www.gnu.org/software/help2man/}) is one way to automate
+generation of a man page, in this case from @option{--help} output.
+This is sufficient in many cases.
