It's up: https://github.com/jsatellite/tlb2d/tree/master/src/tlb2d

There's probably a few bugs, and type libraries have a tendency 
to re-define existing types so you'll have to comment those out. 
Also it doesn't generate dependencies, but it does list them at 
the top of the generated module so you can run the tool on those 
type libraries manually.
