;;; Commentary:

;; Extract the code from source blocks out into raw source-code files.

;;; Code:
(require 'org-babel)

(defvar org-babel-tangle-langs nil
  "Association list matching source-block languages.  The car of
each element should be a string indicating the source block
language, and the cdr should be a list containing the extension
and shebang(#!) line to use when writing out the language to
file.")
