;;; Commentary:
;; Org-Babel support for evaluating ocaml source code. This one will
;; be sort of tricky because ocaml programs must be compiled before
;; they can be run, but ocaml code can also be run through an
;; interactive interpreter.
;;
;; For now lets only allow evaluation using the ocaml interpreter.
