-: > What is a portable (if inefficient or inelegant) replacement for `update'?
-: 
-: `update' was born to replace the GNU-standard move-if-change shell 
-: script

I didn't know about move-if-change, thanks!

But, it seems that `update' and `move-if-change' are different
enough to be dangerous:

        update:  copy src -> dest

        move-if-change: _move_ src -> dest
                        _remove_ src if src==dest       (ouch!)
