Revision 1.1, Sat Jun 22 08:54:13 2013 UTC (8 years, 5 months ago) by schwarze
Branch: MAIN
CVS Tags: VERSION_1_12_3, VERSION_1_12_2

A very simple utility script to automatically compare groff and mandoc
output on collections of manual source files.  I'm using this for quite
some time now, and it has proven to be rather useful.

Obviously, this will not be installed on user's systems.
