Initial darwin documentation archeology.

This is what I could recover of the darwin configuration as it stands on Mini18-Alpha at SimSpace.

I believe this is sufficient for someone skilled in the art to reproduce it without access to the machine, but clearly there are a few holes I don't feel qualified to fill in without trying to set it up again.

@bgamari points out the config could be improved with cores and jobs changing.

@carter Perhaps you could fill in some details?
