I agree with Martin. I would be happy with .R initially and later we could
add other suffixes if we have different data formats. I was just going to
slurp them in through source.

I agree post 0.60 release (but somethings will have to slip in to the Windows
release of 0.60. I can't believe how hard it is to keep the two in sync. It 
would be handy if we could put the .R's on the data files before the release.
I could live with messy documentation but I really don't want to drop down
into the nuts and bolts of some of the windows dialog code.
