    <para>
      <command>dnstap-read</command>
      reads <command>dnstap</command> data from a specified file
      and prints it in a human-readable format.  By default,
      <command>dnstap</command> data is printed in a short summary
      format, but if the <option>-y</option> option is specified,
      then a longer and more detailed YAML format is used instead.
