;; Set up slime-js
;;
;; To install, see https://github.com/swank-js/swank-js/wiki/Installation
;;
;; This is what I did:
;;
;; npm install swank-js -g
;; M-x package-install slime-js
;;
;; The slime-js version in marmalade requires swank 2010.04.04, or at least
;; one prior to the breaking change in 2011.
;;
;; It also requires js2-mode, which is a good choice in either case. I highly
;; recommend this fork:
;;
;; https://github.com/mooz/js2-mode
;;
;; My settings found in this file also requires js2-refactor:
;;
;; https://github.com/magnars/js2-refactor.el
;;
;; I have included this file in init.el like so:
;;
;; (add-hook 'after-init-hook
;; #'(lambda ()
;; (when (locate-library "slime-js")
;; (require 'setup-slime-js))))
;;
