	It might also be a good time to clarify that the sources are still
	'restricted'.  Legally we can share the sources only with other
	license holders.  However the cost of obtaining the license is vastly
	more affordable now than in a previous era.

	Hmmm, didn't the V7 shell borrow from the V6 shell?  Perhaps not
	completely "based on" (as in starting from a copy and editing away).
