	<title>DESCRIPTION</title>
	<para>
		&xsltproc; is a command line tool for applying <acronym>XSLT</acronym>
		stylesheets to <acronym>XML</acronym> documents. It is part
		of <citerefentry>
			<refentrytitle>libxslt</refentrytitle>
			<manvolnum>3</manvolnum>
		</citerefentry>, the XSLT C library for GNOME.
		While it was developed as part of the GNOME project, it can operate
		independently of the GNOME desktop.
	</para>
	<para>
		&xsltproc; is invoked from the command line with the name of the
		stylesheet to be used followed by the name of the file or files to which
		the stylesheet is to be applied. It will use the standard input if a
		filename provided is <emphasis role="bold">-</emphasis> .
	</para>
	<para>
		If a stylesheet is included in an <acronym>XML</acronym> document with a
		Stylesheet Processing Instruction, no stylesheet need to be named at the
		command line. &xsltproc; will automatically detect the included stylesheet
		and use it.
	</para>
	<para>
		By default, output is to <filename class="devicefile">stdout</filename>.
		You can specify a file for output using
		the <option>-o</option> or <option>--output</option> option.
