These are the programs that come with UZI hacked to run under AmigaOS.
They all work on a file called testdev in the current directory.  This
is a 880KB image that should be copied onto a floppy disc at a track
by track level (i.e. not a a file).
mkfs builds a filesystem
fsck checks a filesystem (and seems IMNSHO dodgy)
ucp simulates a cross between a shell and an ftp session.  It lets you
populate the filesystem before trying to boot MAPUX.  See elsewhere for
a description of what files MAPUX expects to find.
