This is a completely wretched thing that implements a RDF-ish database. It works by generating zillions of tiny files. We should never ever really use this; it's just for playing. If we actually ever do ship this, I will be forced to spend the rest of my life hunting down every copy on every machine in the world and eradicating it.
