Hi

I have been following the threads about sexplib/deriving with interest and
have a question
about using sexplib with existing libraries.

Example: If I want to use sexplib with values of type Netdate.t (a date type
from the ocamlnet
library) and try the following:

   type v = { name : string; created_at : Netdate.t} with sexp

then I get the following error when compiling:

     Unbound value Netdate.t_of_sexp

My question is, what is the easiest way to generate the sexp functions for
Netdate.t,
without modifying the code of the Netdate library ?

Best regards
Anders
