Well, strip out all the tree building, actions, etc, and you've got a
plain text version of the EBNF grammar... then you could just use a tool
to prettify it (convert it to whatever you like to do such things in -
LaTeX or whatever).

Of course, if you want pure BNF rather than EBNF, it's a bigger job...
