`dbi_example.ml' is a program which uses the DBI. It requires access
to a database where it can create temporary tables and execute some
simple queries.

Run it interactively just by typing:

	./dbi_example --help

Note at the moment it probably only works with PostgreSQL, or perhaps
Oracle, because we use ANSI-specific data type names.

An example run with PostgreSQL:

	./dbi_example --driver postgres rich

An example run with PostgreSQL using the Perl DBD (requires Perl4Caml
>= 0.3.6 to be installed):

	./dbi_example --driver perl dbi:Pg:dbname=rich
