Usage: $_ME <URI>
$_ME is a wrapper for xmlcatalog. It tries to resolve <URI>
via the catalogs defined in the variable XML_CATALOG_FILES. The catalogs
are used in the order they appear in XML_CATALOG_FILES. Once the URI
is resoved, remaining catalogs are ignored.
Returs 0 and the path to the catalog upon success,
returns 1 if the <URI> could not be resolved.
