+            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.

+            For example, to check for DLV records for "example.com"
+            in ISC's DLV zone, use:
