Ahh, yes. We do actually want that. So yes, we should make only stage 3
have the multiple entries.

Yes, I find the index to be very nice to work with - it basically allows
you to work with multiple trees in one go, instead of working one file at
a time. You just slurp in any number of trees (with some trivial rules
about which stage they go in), and then you can just walk through each
filename and efficiently handle one file at a time without re-doing the
tree thing. Very nice.
