+;;; flymakemsg.el --- Show flymake compile errors in echo area
+;;
+;; Author: Lennart Borgman (lennart O borgman A gmail O com)
+;; Created: 2009-11-21 Sat
+;; Version: 0.1
+;; Last-Updated: 2009-11-21 Sat
+;; URL:
+;; Keywords:
+;; Compatibility:
+;;
+;; Features that might be required by this library:
+;;
+  ;; `backquote', `bytecomp'.
+;;
+;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
+;;
+;;; Commentary:
+;;
+;; Show flymake error messages in minibuffer when point is on a
+;; flymake error overlay.
+;;
+;; To use it just load this file. Put this in .emacs:
+;;
+;;   (require 'flymakemsg)
+;;
+;; This file run `defadvice' on some functions in `flymake-mode'.
+;; This code started from an idea in a paste.
+;;
+;; Note: This code breaks Emacs conventions since it does the
+;; defadvising when you just loads this file.
