;;
;; Syntax check erlang source code on the fly (integrates with flymake).
;;
;; Start using flymake with erlang by putting the following somewhere
;; in your .emacs file:
;;
;; (require 'erlang-flymake)
;;
;; Flymake is rather eager and does its syntax checks frequently by
;; default and if you are bothered by this, you might want to put the
;; following in your .emacs as well:
;;
;; (erlang-flymake-only-on-save)
;;
;; There are a couple of variables which control the compilation options:
;; * erlang-flymake-get-code-path-dirs-function
;; * erlang-flymake-get-include-dirs-function
;; * erlang-flymake-extra-opts
;;
;; This code is inspired by http://www.emacswiki.org/emacs/FlymakeErlang.
