     DESCRIPTION
          /etc/dumptab is an ASCII file containing an entry describing
          media characteristics for each medium made available to
          dump2.

          This table file contains lines in one of three formats:

            a.  comment lines (must start with a "#")

            b.  lines specifying the capacity of the medium:

                       <medium-name>  <buffer-size>  <capacity>

            c.  lines giving the density, tape length, and IRG for the
                medium:

                <medium-name>  <buffer-size>  <density>  <tape-length>  <IRG>

          Fields are separated by white space.  The fields are
          desribed below:

          medium-name
                    descriptive label for the medium.

          buffer-size

                    to the medium.

          capacity  formatted capacity of the medium (in bytes).  The
                    capacity can also be specified as a number
                    followed by a upper or lowercase b, k, m, or to
                    indicate bytes, kilobytes, megabytes, or
                    gigabytes, respectively.

          density   density at which data is written to the device (in
                    bpi).

          tape-length

          IRG       inter-record gap size used by the device (in
