> The FSTs produced by Builder can be further shrunk if you are willing
> to spend highish transient RAM to do so... our Builder today tries
> hard not to use much RAM (and has options to tweak down the RAM usage,
> in exchange for somewhat lager FST), even when building immense FSTs.
> But for apps that can afford highish transient RAM to get a smaller
> net FST, I think we should offer packing.
