;;; acdw-defaults.el --- measured defaults for Emacs -*- lexical-binding: t -*-
;; by C. Duckworth <acdw@acdw.net>

;;; Commentary:

;; I find myself copy-pasting a lot of "boilerplate" type code when
;; bankrupting my Emacs config and starting afresh.  Instead of doing
;; that, I'm putting it here, where it'll be easier to include in my
;; config.

;; Of course, some might say I could just ... stop bankrupting my
;; Emacs.  But like, why would I want to?

;;; Code:
