+;;; eshell-dat.el --- A better `cat' for Eshell -*- lexical-binding: t -*-
+
+;;; Commentary:
+
+;; An alternative to `eshell/cat'.  If you `dat' an image file it will be
+;; displayed as a thumbnail in the terminal similar to Kitty's "icat" or the
+;; "catimg" command.  If you Dat a file it will be shown with syntax
+;; highlighting, sort of like how the "bat" command can be configured.
+
+;; This is mostly lifted directly from
+;; https://emacs.stackexchange.com/questions/3432/display-images-in-eshell-with-iimage-mode
+;; and also a bit from https://github.com/manateelazycat/aweshell/blob/d246df619573ca3f46070cc0ac82d024271ed243/aweshell.el#L775
