monkeyc-mode is a major mode for editing Monkey C file. Adds syntax highlighting.
Download the monkeyc-mode.el and
save the file where Emacs can find it (i.e., a directory in your
load-path). You can then configure monkeyc-mode to load automatically by adding the following to your init file:
(add-to-list 'load-path "/your/path/to/monkeyc-mode/")
(require 'monkeyc-mode)
(add-to-list 'auto-mode-alist '("\\.mc\\'" . monkeyc-mode))
