     DESCRIPTION
          The floppy disk interface serves a one-level directory giv-
          ing access to up to four floppy disk drives.  Each drive is
          represented by a data and control file.  There are no parti-
          tions.

          Messages accepted by the ctl file include:

          eject   Eject the floppy, if possible.
          reset   Reset the drive.
          format type
                  Format the floppy.  The type sets the density and
                  type of disk to be formatted; see format(8).

          A read of the ctl file returns a string describing the form
          factor of the disk, one of 3½DD, 3½HD, 5¼DD, or 5¼HD.
