as noted in that paper, i borrowed the distinction
from the EMAS group, particularly their paper
``An Experiment in Doing it Again, But Very Well This Time''
(CSR-18-77 University of Edinburgh):

	By re-implementation, we mean re-programming and altering the
	structure of an existing system where necessary, so as to better implement
	the function of that system.  We distinguish re-implementation from two
	other activities.  These are the transportation of an existing system to
	new hardware, and the design of a new system.  If we transport a system,
	we leave its function and its structure unaltered.  Re-implementation is
	not merely a combination of transportation and re-design, but is a
	unique activity in its own right.  It is doing it again, but very well this time.
