<title>DESCRIPTION</title>
<para>
The &xmllint; program parses one or more <acronym>XML</acronym> files,
specified on the command line as <replaceable>XML-FILE</replaceable>

is <emphasis role="bold">-</emphasis> ). It prints various types of
output, depending upon the options selected. It is useful for detecting
errors both in <acronym>XML</acronym> code and in
the <acronym>XML</acronym> parser itself.
