Grew emacs mode

The grew emacs mode is defined in the file grew.el You should put this file in a directory that emacs kowns, for instance:

mkdir -p ~/.emacs.d         # Make the directory unless it exists
mv grew.el ~/.emacs.d/      # Move grew.el into that directory

Then add the following lines to your emacs configuration file (usually: ~/.emacs)

;; grew mode
(load-file "~/.emacs.d/grew.el")
(setq auto-mode-alist (cons '("\\.gr[s]?$" . grew-mode) auto-mode-alist))
(autoload 'grew-mode "grew" "Major mode for editing grew files." t)
