#
#	This script rotates isdntrace(8) logfiles and deletes the 
#	oldest ones. isdntrace needs to be started for this to
#	function with the option "-f /var/tmp/isdntrace0", i.e.
#	an entry like:
#		isdn_traceflags="-f /var/tmp/isdntrace0"
#	in /etc/rc.conf will be sufficient. Further, you need to
#	add an entry like this or similar to this:
#		0 0 * * * root /usr/local/etc/doisdnrot 2>&1 | sendmail root
#	to /etc/crontab to rotate the logfiles at every midnight.
