Multipurpose Internet Mail Extensions (MIME)

    The MIME utility is a standalone, user-mode, nonprivileged utility
    that provides MIME interpretation and composition editing.
    Messages in the VMSMAIL MAIL files can be extracted into text files
    and then be read and interpreted using MIME.  MIME formatted text
    files can be composed using MIME, and then sent using VMSMAIL to
    OpenVMS and other systems that have a MIME utility or MIME capable
    MAIL application.
