	Hi Ian,

	You could give doc a shot:

	http://www.shub-internet.org/brad/dns/index.html
	(ftp://ftp.shub-internet.org/pub/shub/brad/dns/doc-2.2.3.tar.bz2)

	... it's ancient and has never heard of DNSSEC, but it still works great to
	root out discrepancies in delegations (including badly synchronized
	secondaries and mismatches in parent/child NSsets).

	Cheers,
	Phil
