I would just like to point out that on most unix systems, mv is also
simply a link to cp and ln.  It could have been implemented this way
on the UNIX-PC also, but the implementers chose to give us two
identical programs in /bin.  One is the linked cp and ln, the other
is mv.  They are byte for byte identical.  The only difference
is the permissions.  Mv is set uid'ed.

If space becomes a premium on the floppy, a few blocks could be saved
by linking mv to cp and ln, then changing permissions on them to
match /bin/mv on the HD (4755, root owner).
