* Summary
  I've really been wanting to have a nicely formatted emacs config file and this is my attempt at it.
* Required Magic
** Lexical Binding

   #+BEGIN_SRC emacs-lisp :results silent
     ;;; -*- lexical-binding: t -*-
     ;;; DO NOT EDIT THIS FILE DIRECTLY
     ;;; EDIT ~init.org~ instead
   #+END_SRC

** The Magical Glue

   The following auto compiles the emacs-lisp within the =init.org= file.
   Simply run `org-babel-tangle` to make it RAIN!

   #+BEGIN_SRC emacs-lisp :results silent
     ;; (setq byte-compile-warnings nil)
     (defun tangle-init ()
       "If the current buffer is 'init.org' the code-blocks are tangled, and the tangled file is compiled."
       (when (equal (buffer-file-name)
                    (expand-file-name (concat user-emacs-directory "init.org")))
         ;; Avoid running hooks when tangling.
         (let ((prog-mode-hook nil))
           (org-babel-tangle)
           (byte-compile-file (concat user-emacs-directory "init.el")))))

     (add-hook 'after-save-hook 'tangle-init)
   #+END_SRC
