;;; sass-mode.el --- Major mode for editing Sass files
|

;; Copyright (c) 2007, 2008 Nathan Weizenbaum

;; Author: Nathan Weizenbaum
|
||||
;; URL: http://github.com/nex3/haml/tree/master
|
||||
;; Version: 1.0
|
||||
;; Keywords: markup, language
|
||||
|
||||
;;; Commentary:
|
||||
|
||||
;; Because Sass'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:
|
||||
;;
|
||||
