There is a hidden gotcha here if you use csh. If the directory to a cd
which is inside the first ()'s is not a full path name, i.e., relies on
cdpath for expansion, the tar chokes. Reason?

	cd echos the path name when the expansion uses cdpath

This is arguably a case for making cd print to stderr or shutting up
totally.

By using rsh and using the B option on the tars, you get a nice
intermachine copier. It has the advantage over rcp of preserving the
times.
