	<para>
		&xmlcatalog; is a command line application allowing users to monitor and
		manipulate <acronym>XML</acronym> and <acronym>SGML</acronym> catalogs. It
		is included in <citerefentry>
			<refentrytitle>libxml</refentrytitle>
			<manvolnum>3</manvolnum>
		</citerefentry>.
	</para>
	<para>
		Its functions can be invoked from a single command from the command line,
		or it can perform multiple functions in interactive mode. It can operate
		on both <acronym>XML</acronym> and <acronym>SGML</acronym> files.
