I modified the original rundig script for the update dig task.
After rundig is done, I will manually copy/move .work files ...
Here is the rundig.update:
# $Id: rundig,v 1.7 1999/01/31 04:27:02 ghutchis Exp $
# This is a sample script to create a search database for ht://Dig.
$BINDIR/htdig -s -a
$BINDIR/htmerge -s -a
