+;;; Commentary:
+
+;; This file exists solely for tangling a Makefile from org-mode files.
+
+;;; Code:
+(require 'ob)
+
+(defvar org-babel-default-header-args:makefile '())
+
+(defun org-babel-execute:makefile (body params)
+  "Execute a block of makefile code.
+This function is called by `org-babel-execute-src-block'."
+  body)
+
+(defun org-babel-prep-session:makefile (session params)
+  "Return an error if the :session header argument is set.  Make
+does not support sessions."
+  (error "Makefile sessions are nonsensical"))
+
+(provide 'ob-makefile)
