;;; early-init.el -*- lexical-binding: t; coding: utf-8-unix -*-
;; Author: Case Duckworth <acdw@acdw.net>
;; Created: Sometime during Covid-19, 2020
;; Keywords: configuration

;;; Comentary:
;; Starting with Emacs 27.1, `early-init' is sourced before `package'
;; or any frames. So those are the settings I run in this file.
;;; Code:
;;; Add `acdw.el'
(push (expand-file-name "lisp/" user-emacs-directory)
load-path)
