122 | =head1 DESCRIPTION | |
123 | ||
124 | This program is part of mharc, and has the responsibility of performing | |
125 | garbage collection on archive search indexes. | |
126 | ||
127 | Generally, this program will be invoked automatically from C<cron> | |
128 | on a periodic basis. | |
129 | ||
130 | This program will use the C<HTML_DIR> variable from | |
131 | C<E<lt>mharc-rootE<gt>/lib/config.sh> as the root directory to search for | |
132 | searchable archives. | |
