1.0->1.1 (18 Dec 2001)

Sophos deleted INTERCHK from the CD so now the script looks for the
DISKIMGS and TOOLS directories to identify the CD as a Sophos one.

If /mnt/cdrom is not mounted when the script runs, mount /dev/cdrom
before checking and unmount it again before exiting.

Virus administrator(s) and sysadmin are now defined at the top of
each script. Define the sysadmin with a leading comma, or leave the
definition completely blank.

1.1->1.2 (07 Aug 2003)

The "top directory" is now explicitly defined at the top of each
script. If you install Sophos in /home/sweep as I do, you will need
to edit this. The current settings match Sophos' default (/usr/local).

Since /usr/local/tmp normally doesn't exist, the scripts will
use $TMPDIR for scribbling if $TOPDIR/tmp doesn't exist.
