+;; Flymake is a minor Emacs mode performing on-the-fly syntax checks.
+;;
+;; This file contains the most original implementation of flymake's
+;; main source of on-the-fly diagnostic info, the external syntax
+;; checker backend.
+;;
+;;; Bugs/todo:
+
+;; - Only uses "Makefile", not "makefile" or "GNUmakefile"

;;; Commentary:
;;
-;; Flymake is a minor Emacs mode performing on-the-fly syntax checks
-;; using the external syntax check tool (for C/C++ this is usually the
-;; compiler).
-
-;;; Bugs/todo:
-
-;; - Only uses "Makefile", not "makefile" or "GNUmakefile"
-;; (from http://bugs.debian.org/337339).
+;; Flymake is a minor Emacs mode performing on-the-fly syntax checks.
+;;
+;; It collects diagnostic information for multiple sources and
+;; visually annotates the relevant lines in the buffer.
+;;
+;; This file is just a stub for that loads the UI and backends, which
+;; could also be loaded separately.
