/**
* Provides a driver to convert MARCXML records to MARC format.
*
* <p>
* The following example reads input.xml and writes output to the console:
* </p>
*
* <pre>
* java org.marc4j.util.XmlMarcDriver input.xml
* </pre>
*
* <p>
* The following example reads input.xml, converts UTF-8 and writes output in
* MARC-8 to output.mrc:
* </p>
*
* <pre>
* java org.marc4j.util.XmlMarcDriver -convert MARC8 -out output.mrc input.xml
* </pre>
*
* <p>
* It is possible to pre-process the input file using an XSLT stylesheet. The
* transformation should produce valid MARCXML. The following example transforms
* a MODS file to MARCXML and outputs MARC records.
* </p>
*
* <pre>
* java org.marc4j.util.XmlMarcDriver -convert MARC8 -out output.mrc -xsl http://www.loc.gov/standards/marcxml/xslt/MODS2MARC21slim.xsl modsfile.xml
* </pre>
*
* <p>
* For usage, run from the command-line with the following command:
* </p>
*
* <pre>
* java org.marc4j.util.XmlMarcDriver -usage
* </pre>
*
* <p>
* Check the home page for <a href="http://www.loc.gov/standards/marcxml/">
* MARCXML </a> for more information about the MARCXML format.
