1;;; +emacs.el --- measured defaults for Emacs -*- lexical-binding: t -*-

3;;; Commentary:

5;; I find myself copy-pasting a lot of "boilerplate" type code when
6;; bankrupting my Emacs config and starting afresh. Instead of doing
7;; that, I'm putting it here, where it'll be easier to include in my
8;; config.
9
10;; Of course, some might say I could just ... stop bankrupting my
11;; Emacs. But like, why would I want to?
