What Todd is trying to say is that if a program knows it needs a more
recent version of the O/S (or Tools) it should call GetVersion and
safely exit if the version is too old. The reason he says this is because
too many program require recent O/S yet, crash if not available w/o telling
the user why it is crashing. Everyone ends up thinking it doesn't
work on ROM 3 or theyt don't have enough memory...
