;;; colorscheme.el --- Syntax highlight and friends -*- lexical-binding: t -*-

;; Author: William Carroll <wpcarro@gmail.com>
;; Version: 0.0.1
;; Package-Requires: ((emacs "24.3"))

;;; Commentary:
;;
;; TODO: Clarify this.
;; Since I have my own definition of "theme", which couples wallpaper, font,
;; with Emacs's traditional notion of the word "theme", I'm choosing to use
;; "colorscheme" to refer to *just* the notion of syntax highlight etc.
