-;;; haml-mode.el --- Major mode for editing Haml files
-
-;; Copyright (c) 2007, 2008 Nathan Weizenbaum
-
-;; Author: Nathan Weizenbaum
-;; URL: http://github.com/nex3/haml/tree/master
-;; Version: 3.0.14
-;; Created: 2007-03-08
-;; By: Nathan Weizenbaum
-;; Keywords: markup, language, html
-
-;;; Commentary:
-
-;; Because Haml's indentation schema is similar
-;; to that of YAML and Python, many indentation-related
-;; functions are similar to those in yaml-mode and python-mode.
-
-;; To install, save this on your load path and add the following to
-;; your .emacs file:
-;;
-;; (require 'haml-mode)
