"ocaml_beginners"::[] Getting started with Camlp4

Hi -

I'd like to start playing around with the 3.10 version of Camlp4.
Getting started is difficult because the amount of
information/examples out there is still in its infancy.

In the 3.09 version of Camlp4 I like to visualize the grammar and
figure out which point to extend by typing in:

Grammar.Entry.print Pcaml.expr;;

Is there something similar I can do with Camlp4 3.10? Otherwise, what
methods are people using to figure out the structure of the original
OCaml grammar?

Thanks,

Andy

According to the article about camlp4 3.10 in the OCaml Journal, you do:

# Gram.Entry.print Format.std_formatter Syntax.expr;;
