    <para><command>dnssec-checkds</command>
      verifies the correctness of Delegation Signer (DS) or DNSSEC
      Lookaside Validation (DLV) resource records for keys in a specified
      zone.

	<listitem>
	  <para>
	    Specify a digest algorithm to use when converting the
	    zone's DNSKEY records to expected DS or DLV records. This
	    option can be repeated, so that multiple records are
	    checked for each DNSKEY record.
          </para>
          <para>
            The <replaceable>algorithm</replaceable> must be one of
            SHA-1, SHA-256, or SHA-384.  These values are case insensitive,
            and the hyphen may be omitted.  If no algorithm is specified,
            the default is SHA-256.

            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.

            Check for a DLV record in the specified lookaside domain,
