		<span class="command"><strong>xmlcatalog</strong></span> is a command line application allowing users to monitor and

		is included in <span class="citerefentry"><span class="refentrytitle">libxml</span>(3)</span>.
	</p><p>
		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 class="acronym">XML</acronym> and <acronym class="acronym">SGML</acronym> files.

		Invoking <span class="command"><strong>xmlcatalog</strong></span> non-interactively without a designated action
		(imposed with options like <code class="option">--add</code>) will result in a lookup
		of the catalog entry for <em class="replaceable"><code>ENTITIES</code></em> in the
		catalog denoted with <em class="replaceable"><code>CATALOGFILE</code></em>. The
		corresponding entries will be output to the command line. This mode of
		operation, together with <code class="option">--shell</code> mode and non-modifying
		(i.e. without <code class="option">--noout</code>) direct actions, allows for
		a special shortcut of the void <em class="replaceable"><code>CATALOGFILE</code></em>
		specification (possibly expressed as "" in the shell
		environment) appointing the default system catalog. That simplifies the
		handling when its exact location is irrelevant but the respective built-in
		still needs to be consulted.
