some small example using s-expressions

[Ashish Agarwal]

In _oasis, add sexplib.syntax to BuildDepends.

Make your _tags file like this:

$ cat _tags
# OASIS_START
# OASIS_STOP

<.ml{,i}>: syntax_camlp4o

Then, create some type defs:

$ cat a.ml
type t = A | B of int
with sexp

And similarly add "with sexp" in your .mli files if you want the sexp
converters available in the interface. You'll get extra functions t_of_sexp
and sexp_of_t. Biocaml does this, so you can see that code for an example.
