26;;; Commentary:
27;;
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)
31
9f812d23
SM		 32;;; Bugs/todo:
33
34;; - Only uses "Makefile", not "makefile" or "GNUmakefile"
35;; (from http://bugs.debian.org/337339).
