    <title>DESCRIPTION</title>
    <para>
      <command>named-journalprint</command>
      prints the contents of a zone journal file in a human-readable
      form. 
    </para>
    <para>
      Journal files are automatically created by <command>named</command> 
      when changes are made to dynamic zones (e.g., by
      <command>nsupdate</command>).  They record each addition
      or deletion of a resource record, in binary format, allowing the
      changes to be re-applied to the zone when the server is
      restarted after a shutdown or crash.  By default, the name of
      the journal file is formed by appending the extension
      <filename>.jnl</filename> to the name of the corresponding
      zone file.
    </para>
    <para>
      <command>named-journalprint</command> converts the contents of a given
      journal file into a human-readable text format.  Each line begins
      with "add" or "del", to indicate whether the record was added or
      deleted, and continues with the resource record in master-file
      format.
