I suspect this is the wrong question to be asking.  Are you really wanting
to print "10.5" or "10.6"?  Or are you asking because feature X is not
available on older versions?  Or does feature Y exist but crash
frequently?  Is feature Y's fix readily detectable?

Feature-specific tests that probe for functionality often perform better
than hard coded lookup tables of known configurations (that don't handle
unusual configurations and aren't updated in the future)...
