;;; 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.
