While learning OCaml, I just coded a small program that dumps
the full content of a cmi file. I find this more usefull than
ocamlbrowser or to use the toplevel to have a small command line
driven dumper, and it was also a good pretext to have a look
under the cover.

The problem is : most of the usefull types and functions are
installed in the toplevellib.cma but I can't use this without
the proper cmi files (I need config.cmi for cmi_magic_number,
printtyp.cmi and typemod.cmi for printing signatures, but
env.cmi would be nice to have as well for read_signature).

Of course I can use those left in ocaml-3.11.1 directory after
compilation, but having them installed would help the creation
and distribution of such tools.

But maybe there is an other way to use toplevellib.cma that I'm
unaware of ? If not, then why not install these cmi files along
with toplevellib ?

Anyway, if anyone is interrested the tool is attached.
