+;;; 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?
