;;; Commentary:
;;
;; To Do:
;;
-;; * makefile-backslash-region should be given better behavior.
-;; * Consider binding C-c C-c to comment-region (like cc-mode).
+;; * Add missing doc strings, improve terse doc strings.
;; * Eliminate electric stuff entirely.
;; * It might be nice to highlight targets differently depending on
;; whether they are up-to-date or not. Not sure how this would
;;; Code:
-(provide 'makefile)
-
;; Sadly we need this for a macro.
