I agree. I believe you may have the rights now.

A bit more investigation later, I ended up installing the META file
under /usr/lib/ocaml/mcl (I didn't know META had to go under a directory
with the same name as the package under ocaml). It seemed like ocamlfind
list wouldn't display "mcl", so I did `XMETAExtraLines: directory = "^"`
in _oasis and now I see mcl under ocamlfind list.

Thanks for the help. Although, do feel free to push any changes /
improvements you feel necessary.

Kind regards,
Shayan Doust
