;;; Commentary:
;; I /was/ going to convert this to org-mode, but then I found this
;; page: https://yiufung.net/post/pure-emacs-lisp-init-skeleton/,
;; which pointed out that I could use `outline-mode' (or in my case,
;; `outshine') to fold and navigate a pure-elisp `init.el'. So that's
;; what I'm doing.
;;; Basic emacs config & built-in packages
;;;; /Really/ basic emacs config
;; I /did/ use `better-defaults', but it turns out that that package
;; is (a) short and (b) mostly overriden by other settings.
