	First pass at have a "listen" directive for reading the detail file:

	listen {
		type = detail
		file = ${logdir}/blah/detail
	}

	It requires sending an initial RADIUS packet to get it to start
	reading the detail file, and the locking algorithm is the
	new one as posted by Miquel, not the old one.  So don't try
	running this in a "live" system as yet.

	But it works.
