;; Commentary:

;; This file implements basic emacs support for webby, a website compiler written
;; in ruby.  Webby can be found at http://webby.rubyforge.org/.
;;
;; This is a very early release with few features. The interface is
;; still subject to change, although changes will be done only for a
;; good reason. Documentation is still very sparse.
