We did this sort of thing with C compilers, too.  The idea is:
	PHASE 0 (existing practice):  All applications use "awk".
	PHASE 1:  New awk installed as "nawk", old awk remains as "awk",
		"oawk" linked to "awk".
	PHASE 2 (transition):  Applications that require the new
		behavior invoke "nawk".  Old applications are tested
		against "nawk" and if they really do require the old
		version, they are changed to invoke "oawk"; otherwise
		they continue to invoke "awk".
	PHASE 3: "awk" is changed to be a link to "nawk".
	PHASE 4 (catch-up):  Applications that rely on "oawk"-specific
		behavior are updated to work with regular (new) "awk".
