# And if you find yourself getting e-mails, use the following instead:
#    0,10,20,30,40,50 * * * *   /path/to/ihostchk.sh >/dev/null 2>&1
# NOTE: e-mails should only be sent if an error occurs, so the former is
#       the best choice for a cronjob.

State:	*FILE REMOVED*
Log Message:	Removed some un-used code from CVS. We can always resurrect this later if someone feels they want to work on it. Gone are the old perl ihost which isn't needed now, winhost which is broken and shows no sign of being fixed, and DBReporter. If someone wants to revive them, I'll undelete them :-)
