Hi Scot,

I've added some simplifying functions to the literate programming
functionality of org-babel.  It should now be easy to embed your elisp
initialization into org-mode files.  Specifically there is now a new
`org-babel-load-file' function which can load the elisp portions of
org-mode files in the same manner as the normal `load-file' command.

To use this you need to clone the latest version of org-babel[1], and
then add the following to your emacs initialization (this worked for me
when a base emacs "emacs -Q").

--8<---------------cut here---------------start------------->8---
(add-to-list 'load-path "~/path/to/org/lisp")
(add-to-list 'load-path "~/path/to/org-babel/lisp")
(require 'org-babel-init)
;; now you can load your org-mode files with embedded elisp
(org-babel-load-file "~/path/to/org-mode-file.org")
;; for example
(org-babel-load-file "~/path/to/org-babel/test-tangle.org")
--8<---------------cut here---------------end--------------->8---

Hopefully this will provide the literate programming functionality
without too much trouble.

Cheers -- Eric
