not sure if tech-userlevel is a good place to ask this.

	does UCB license change (from 4-clause to 3-clause) cover code that is
	not originally shipped with 4.4BSD?  here we are changing license on
	BIND8 (BIND8 was not in 4.4BSD, BIND4 was), ISC DHCP and tcpdump.
	files *may* have derived from 4.4BSD code, but i'm just not sure if
	these BIND8 source code are covered by UCB license change.
