This file creates a new mode (based on python-mode) to highlight keywords specific to Enaml files. Just copy the file enaml.el to a location in your load-path (typically "~/.emacs.d" for an individual user). Then add the following lines to your .emacs file:
(require 'enaml)
(setq auto-mode-alist (cons '("\\.enaml$" . enaml-mode) auto-mode-alist))
Inline python code should still be highlighted as in python-mode.
