;;; wip.el --- test code -*- lexical-binding: t; coding: utf-8; -*-
;; author: Craig Jennings <c@cjennings.net>
;;
;;; Commentary:
;;
;; Work-in-progress and experimental code testing area. This file contains
;; code that is being actively developed or tested before being promoted
;; to stable configuration modules. Functions here may be incomplete,
;; buggy, or subject to significant changes. Include this file at the end
;; of init.el so that if something breaks, most of the Emacs config has
;; already loaded. Once code has been tested and proven stable, graduate
;; it into the appropriate configuration module. Do not rely on this code
;; for production use.
