+ <para>
+ If a <option>file</option> is specified, then the zone is
+ read from that file to find the DNSKEY records. If not,
+ then the DNSKEY records for the zone are looked up in the DNS.

+ <para>
+ Check for a DLV record in the specified lookaside domain,
+ instead of checking for a DS record in the zone's parent.
+ For example, to check for DLV records for "example.com"
