;; By default, CFEngine 3.x syntax is used.
;; You can set it up so either `cfengine2-mode' (2.x and earlier) or
;; (add-to-list 'auto-mode-alist '("^cf\\." . cfengine2-mode))
;; (add-to-list 'auto-mode-alist '("^cfagent.conf\\'" . cfengine2-mode))
+;; It's *highly* recommended that you enable the eldoc minor mode:
+
+;; (add-hook 'cfengine3-mode-hook 'eldoc-mode)
+
+;; You may also find the command `cfengine3-reformat-json-string'
+;; useful, just bind it to a key you prefer. It will take the current
+;; string and reformat it as JSON. So if you're editing JSON inside
+;; the policy, it's a quick way to make it more legible without
+;; manually reindenting it. For instance:
+
+;; (global-set-key [(control f4)] 'cfengine3-reformat-json-string)
+
;; This is not the same as the mode written by Rolf Ebert
;; <ebert@waporo.muc.de>, distributed with cfengine-2.0.5. It does
;; better fontification and indentation, inter alia.
