For a while now, I'd been meaning to convert my .emacs to the exciting, new style using org mode's literate programming capabilities.

I'd been impressed by the clarity of Sacha Chua's and, while I haven't quite hit that level of cleanliness, yet, I feel much better about how mine looks, now. I also started using John Wiegley's use-package, which I don't completely understand, yet, but it seems to be a real boon for cleaning up loading and configuring packages.

Even setting up slime, which I use through the quicklisp setup, is easy to load:

(use-package slime
:load-path "~/quicklisp/slime-helper.el")
