hexmode

;; 
;; Emacs smart tabs functionality
;;   Intelligently indent with tabs, align with spaces!
;; 
;; Note: Indenting only uses tabs when indent-tabs-mode is non-nil,
;; otherwise it uses spaces as usual.
;; 
;; To use: save as smarttabs.el in your .emacs.d directory, and add
;; "(require 'smarttabs)" to your .emacs file.
