/**
 * Blast2XML is an application for the conversion native output from
 * BLAST-like bioinformatics software into an XML format.
 * <p>
 * For currently supported bioinformatics programs, please see the
 * documentation for the BlastLikeSaxParser.
 * This class simply wraps the functionality of BlastLikeToXMLConverter.
 * Please see the documentation of this  class for a documented example
 * of how to use the parsing framework.
 * <p>
 * The XML produced should validate against the biojava
 * BlastLikeDataSetCollection DTD.
 * <p>
 * Usage is:<pre><font color="#0000FF">
 * java Blast2XML &lt;blastlike pathname&gt; [-mode &lt;strict|lazy&gt;]
 * </font></pre>
 * -mode is optional paramater. Choosing strict mode will mean the
 * application throws exceptions if the precise version of a given
 * piece of bioinformatics software is not recognised. Lazy mode will
 * attempt to parse the file regardless of version number.
 * <p>
 * For programs currently supported, please see the documentation
 * for the BlastLikeSAXParser.
