 <refsect1><title>DESCRIPTION</title>
  <para>
   <command>yaz-marcdump</command> reads MARC records from one or
   more files.
   It parses each record and supports output in line-format, 
   ISO2709, MARCXML, MarcXchange as well as Hex output.
  </para>
  <para>
   This utility parses records ISO2709(raw MARC) as well as XML
   if that is structured as MARCXML/MarcXchange.
  </para>
  <note>
   <para>
    As of YAZ 2.1.18, OAI-MARC is no longer supported.
    OAI-MARC is deprecated. Use MARCXML instead.
   </para>
  </note>
  <para>
   By default, each record is written to standard output in a line
   format with newline for each field, $x for each subfield x.
   The output format may be changed with option <literal>-o</literal>,
  </para>
  <para>
   <command>yaz-marcdump</command> can also be requested to perform
   character set conversion of each record.
  </para>

    <term>-l <replaceable>leaderspec</replaceable></term>
    <listitem><para>
      Specify a simple modification string for MARC leader. The
      <replaceable>leaderspec</replaceable> is a list of pos=value
      pairs, where pos is an integer offset (0 - 23) for leader. Value
      is either a quoted string or an integer (character value in decimal).
      Pairs are comma separated. For example, to set leader at offset 9
      to a, use <literal>9=a</literal>.

   <varlistentry>
    <term>-s <replaceable>prefix</replaceable></term>
    <listitem><para>
      Writes a chunk of records to a separate file with prefix given,
      i.e. splits a record batch into files with only at most
      "chunk" ISO2709 record per file. By default chunk is 1 (one record
      per file). See option <literal>-C</literal>.

  <para>
   The following command converts MARC21/USMARC in MARC-8 encoding to
   MARC21/USMARC in UTF-8 encoding. Leader offset 9 is set to 'a'.
   Both input and output records are ISO2709 encoded.
   <screen>
    yaz-marcdump -f MARC-8 -t UTF-8 -o marc -l 9=97 marc21.raw >marc21.utf8.raw
   </screen>
  </para>
  <para>
   The same records may be converted to MARCXML instead in UTF-8:
   <screen>
    yaz-marcdump -f MARC-8 -t UTF-8 -o marcxml marc21.raw >marcxml.xml
   </screen>
