Re: Grammar railroad diagram

Hello Andres !

There is two ways to achieve it:

-1 I just add the bison grammar in CocoR format here 
https://github.com/mingodad/CocoR-CPP in the examples folder.

-2 I created an small extension to Bison to do the same and published 
the patch here 
https://github.com/mingodad/bison/commit/da84329ebe5f4bc111ef34b2d46088b655a217f3 
(bison -e yourgramar.y)

And optionally to have the best railroad diagram we need to add the 
"Tokens" manually.

Cheers !
