      <span class="application">xmlcatalog</span> is a command line application
      allowing users to monitor and manipulate <span class="acronym">XML</span> and
      <span class="acronym">SGML</span> catalogs. It is included in
      <span class="application">libxml2</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 <span class="acronym">XML</span> and <span class="acronym">SGML</span> files.
