This seems similar to the recursive MPD problem. At least with the lich.dat
example the files weren't really recursive. It was just a matter of
the ring2.dat file in the local MPD scope supplanting the ring2.dat from the
global parts/primitives scope.
Perhaps when parsing we should (internally to the program) tack the name of
the MPD file onto the name of the subfile to keep the scope local. This way
we could tell house1.mpd.roof.dat apart from house2.mpd.roof.dat. Also
lich.mpd.ring2.dat is now different from p/ring2.dat
Of course this falls into the you implement it and I merely port it category
so feel free to tear this idea apart. :^)

| 1. Are the files in an MPD public or private? Consider this example with three files: town.dat 1 16 -40 0 0 1 0 0 0 1 0 0 0 1 house1.mpd 1 16 40 0 0 1 0 0 0 1 0 0 0 1 house2.mpd house1.mpd 0 FILE house1.dat 1 4 0 0 0 1 0 0 0 1 0 0 0 1 3003.DAT 1 4 0 (...)
