And one last request... Since I'm manually including easy_tokens.mly  
in the menhir command line I tell ocamlbuild to ignore it with - 
ignore Easy_tokens. I do open Easy_tokens in the lexer.

How can I make the lexer module depend on the parser so that the  
parser is always built first?

This is what happens now. Have I painted myself into a corner?

ocamlfind ocamlc -package ounit -c -o easy_lexer.cmo easy_lexer.ml
+ ocamlfind ocamlc -package ounit -c -o easy_lexer.cmo easy_lexer.ml
File "easy_lexer.mll", line 6, characters 2-18:
Unbound module Easy_tokens
Command exited with code 2.

	Thanks, Joel
