The DCF utility is used by PMDF-MR to convert WPS and DX
    message bodyparts to ASCII. This facility is built from document
    conversion software supplied as part of the MRGATE kit (version
    3.1 or 3.2), the Message Router VMS MAIL gateway. PMDF-MR will
    function without this utility but it will be unable to convert
    WPS and DX bodyparts to ASCII.
