I started on a hybrid EMBL parser which combined tag-value and
JFlex/CUP for the feature table, but gave it up for more interesting
things. (It was a real drag trying to get conflicts in the feature
table BNF to resolve and then there's the syntax errors in the DB
itself.)
I'd help with this. I'm messing with the same thing in Lisp, so it
would be an interesting excercise. (Dammit! I *swore* I'd never do
another EMBL parser!)
