Cool!

I have not looked into all the details, from the surface, LGTM.

However, I note that:

On a side note, have you tried to replace boot/ocamlc (and friends) with
the bootstrapped ones (camlboot -> ocaml-4.07 -> *).  Other said, what
is the most affordable path to exploit camlboot and have a good
bootstrapping story for OCaml.


Cheers,
simon
