I'd just like to state that I'd also like to be able to export stl files from the command line to do automated checking for parts with bad BFC winding and parts that aren't watertight in the entire library using already existing freely available utilities. That's the only thing technically keeping the LDraw library from being 3d printer ready (besides the fact that most commonly available 3d printers aren't accurate enough to reproduce parts with anywhere near the required tolerances for actual use, but hopefully that'll resolve itself eventually).
Many thanks for all your excellent work over the years.
