That's normal, everyone does, at some point. Especially when you start
having Parameterized Modules (called Functors in ML) all over the
place.

For a comprehensive source of information, there is the OCaml manual:

http://caml.inria.fr/pub/docs/manual-ocaml/manual004.html

For a tutorial on modules, I would recommend Chapter 14 of "Developing
Applications With Objective Caml":

http://caml.inria.fr/pub/docs/oreilly-book/html/index.html


Hope this helps,
