My only suggestion is: don't generate binary intermediate files,
generate human readable text files instead (read Bently's "Programming
Pearls" and "More Programming Pearls" for why).


Provide a perl module to parse these tables into perl structures
and generate xvcg/dotty or whatever graph files from them.


I think this could be quite useful for "visualising" grammars.
