The PMDF DIRSYNC/DIRBOT utility can be used to run a SYNC_DIRBOT
    channel. If no qualifiers are specified, this is equivalent to

    $ @PMDF_COM:MASTER SYNC_DIRBOT

    Special qualifiers can be used to override the normal operation
    of the channel.

    Using the /LEFTOVERS qualifier forces the DIRBOT to use any
    .OLD LDIF files for directories that do not currently have new
    LDIF files present. When a directory update is forced with the
    /LEFTOVERS switches, and no cookie is available to send back to a
    directory, the cookie value "biscuit" is used. The various sync_
    xxx_master channels know about this value and will accept the
    update.

    The /UPDATE or /NOUPDATE qualifier can be used to control
    just which directories will be sent the results of the DIRBOT
    processing.
