+-----------

+logargs.sh

+

+line arguments it is trying to use.
+
+mkcdb.pl
+--------
+
+A Perl script for a converting flat file into a format that is suitable for

+cdbmake-12 awk script.
+
+ratelimit.pl
+------------
+

+reasonable limit would be before deploying the feature.
+
+unknownuser.sh
+--------------
+
