Add "./unrealircd croncheck" which will start UnrealIRCd if it isn't running and bail out quietly otherwise. This can be used from *surprise!* crontab. The old broken cron script has been removed. (#4508)

-# This is a script suitable for use in a crontab.  It checks to make sure
-# your ircd is running.  YOU NEED A SEPARATE CRON JOB FOR EACH IRCD.  If your
-# ircd isn't found, it'll try to start it back up.
-#
-# You'll need to edit this script for your ircd.
-#
-# To check for your ircd every 10 minutes, put the following line in your
-# crontab:
-#    0,10,20,30,40,50 * * * *   /home/mydir/ircdchk
-# And if you don't want to get email from crontab when it checks you ircd,
-# put the following in your crontab:
-#    0,10,20,30,40,50 * * * *   /home/mydir/ircdchk >/dev/null 2>&1
