+;;; terminal.el --- My cobbled together terminal -*- lexical-binding: t -*-
+;; Author: William Carroll <wpcarro@gmail.com>
+
+;;; Commentary:
+;; My attempts at creating a sane Emacs terminal.  Most of this work was created
+;; before I discovered and fully adopted EXWM.  Prior to this, the appeal of
+;; having terminals inside of Emacs was appealing.  So appealing in fact that I
+;; was willing to work with inferior alternatives to non-Emacs terminals
+;; (e.g. `ansi-term') instead of GUI alternatives like `alacritty` because the
+;; productivity gains of having a terminal inside of Emacs might outweigh the
+;; shortcomings of that particular terminal.
+;;
+;; All of this changed, however, after discovering EXWM, since I can embed X11
+;; GUI windows inside of Emacs.  Therefore, most of this module is maintained
+;; for historical purposes.
+;;
+;; Benefits of `ansi-term':
+;; - Color scheme remains consistent between Emacs and terminal.
+;; - Same applies to my fonts.
+;;
+;; Downsides of `ansi-term':
+;; - Paging feels sluggish with programs like `cat` and `less`.
+;; - KBDs don't provide 100% coverage of what I expect from a terminal since
+;;   they were created to cooperate with Emacs.
