This file is meant to be invoked by a toplevel and performs initialization
of OCaml Batteries Included and its libraries.

Initialization consists of
- loading Findlib
- loading dependencies
- loading the contents of the on-line help system
- printing a welcome message

This file is loaded by the magic line in the ocamlinit file.
