Folks, I too have checked in some stuff today, but in a much
less organized way than Jonathan :-)

I don't think there's anything at all that will affect
people except I am trying to teach the ARK code to use a
particular Unix group (if specified in the XML).  This is
harder than it seems :-( [I might post a question about this
later...], and I'd suggest staying well away from that stuff
until you hear otherwise.
