+;;; Commentary:
+;;;
+;;; TODO Make that big regexp for x86 assembly instructions actually match
+;;; inside comments, where they actually appear. Right now, the syntax table
+;;; entries for the comments overrides the font-lock keywords.
+;;;
+;;; Code:
+(defvar hex0-mode-hook nil)
+
+(defvar hex0-mode-map
+  (make-keymap)
+  "Keymap for hex0 major mode.")
+
+;;;###autoload
+(add-to-list 'auto-mode-alist '("\\.hex0\\'" . hex0-mode))
