Chris,

I like Spirit and have a production system that parses a particular
vendors data packets using it.  Works well.  My only real complaint
about Spirit is that it is quite a slow parser.  This could be
improved by having first / follow set kind of things without an
interface change.  Spirit is quite good at representing the LL
grammars you normal deal with when doing RDP.

Do you have an example of two small grammars that might highlight why
YARD is better?

Matt
