You bring up a valid concern.  It is not easy for an ULTRIX customer
today to figure out what version of the basesystem is running on a
workstation.  This concern will likely be addressed in an upcoming
release.  In the interim, here is how I map UWS (ULTRIX workstation
software) versions to ULTRIX base-system versions:

	UWS Version	Inferred ULTRIX version
	~~~~~~~~~~~	~~~~~~~~~~~~~~~~~~~~~~~
	    1.1			2.2
	    1.2			2.3
	    2.0			3.0
	    2.1			3.1

While I believe the above to be accurate, any errors are mine and
not my employer's.  (standard disclaimer)
