25 ;;; Commentary:
27 ;; Flymake is a minor Emacs mode performing on-the-fly syntax checks
28 ;; using the external syntax check tool (for C/C++ this is usually the
29 ;; compiler).
31 ;;; Bugs/todo:
33 ;; - Only uses "Makefile", not "makefile" or "GNUmakefile"
34 ;; (from http://bugs.debian.org/337339).
