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