<para>
The xmllint program parses one or more XML files, specified on the
command line as <replaceable>xmlfile</replaceable>. 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.
