/UPDATE=dirlist
       /NOUPDATE=dirlist

    By default, if neither /UPDATE nor /NOUPDATE is specified,
    the DIRBOT sends its updates resulting from processing as
    normal, as specified in its option file. Use of /UPDATE or
    /NOUPDATE can be used to override the normal handling. Specifying
    /UPDATE=(dir1,dir2,...) will cause the updates to be sent only
    to the specified list of directories dir1,dir2,.... Specifying
    /NOUPDATE=(dir1,dir2,...) will cause the updates to be sent
    to all directories except the specified list of directories
    dir1,dir2,....
