Supported systems include Unix, VMS, Mac,and Win32.  These modules all offer a <tt class="literal">catfile</tt> class method thatcatenates together each path component using the specified platform'spath separator.  The <tt class="literal">File::Spec</tt> module returns different resultsdepending on your current platform.  The others return resultsspecific to that platform.
