Thanks for your great effort, BTW.

Confused by the requirement:

;; To activate ob-prolog add the following to your init.el file:
;;
;;  (eval-after-load 'org
;;    '(require 'org-prolog))

My Emacs ( 24.5.1) gives an error with this line. I know I'm probably
missing something obvious, but what is org-prolog?
