		<title>The &DB2LaTeX; mapping system <filename>latex.mapping.xsl</filename></title>
		<partintro>
			<section><title>Introduction</title>
			<para>The &DB2LaTeX; mapping system centralises the mapping
			of &DocBook; tags (e.g. <doc:db>chapter</doc:db>)
			to &LaTeX; commands (e.g. <function condition="latex">chapter</function>).
			It uses an auxiliary file, <filename>latex.mapping.xml</filename>,
			to define the start and end of each mapping.
			You can override this <quote>mapping file</quote>
			in order to customise &DB2LaTeX;.</para>
