;;;  Provide an emacs mode for interfacing to the festival speech
;;;  synthesizer system
;;;
;;;  I've looked at many examples from the emacs Lisp directory
;;;  copying relevant bits from here and there, so this can only
;;;  reasonably inherit the GNU licence (GPL)
;;;
;;;  Setup:
;;;  In your .emacs add the following 2 lines to get a Say menu:
;;;
;;;  (autoload 'say-minor-mode "festival" "Menu for using Festival." t)
;;;  (say-minor-mode t)
;;;  (setq auto-mode-alist 
;;;     (append '(("\\.festivalrc$" . scheme-mode)) auto-mode-alist))
;;;
;;;  The following gives you pretty colors in emacs-19 if you are into
;;;  such things 
;;;  ;;;  Some colors for scheme mode
;;;  (hilit-set-mode-patterns
;;;   '(scheme-mode)
;;;   '(
;;;     (";.*" nil comment)
;;;     (hilit-string-find ?\\ string)
