Definitely this option.

One thing that may be very important is if people have corrupted databases (they may not realise that they do have a corrupt .bbb file). I'd suggest making sure the translation routine was pretty easy going about this (obviously, it's unlikely the translator will be able to fix the .bbb file, but it would be better if the translator did not just die if it came across some corruption).
