Mdump and st together provide a coherent method for organizing multiple
instances of dump(8) onto a single magnetic tape volume.

Several assumptions have been made: 1) filesystems are backed up on a
daily basis capturing changes made in the last 24 hours or since the
last weekly.  Weekly tapes capture all changes made since the last 
level 0 dump.

To install, edit the #defines's in mdump.c to properly reflect the
desired commands.  The dump command issued via a system() call is
built in the wrt_dmp() procedure.

Copy dumptab.h to /usr/include.

Edit etc.dumptab to reflect the order desired in dumping filesystems
and the day-of-week for the weekly dump.  I recommend putting the
smaller filesystems first on the tape.  Should the tape volume overflow,
a smaller number of individual tapes will be needed to dump the
remaining filesystems.

Copy etc.dumptab to /etc/dumptab.

Run "make", then "make install".
