Private spacemacs layer to try out Chris Done's Intero mode for haskell

packages.el

;; 1. place this in ~/.emacs.d/private/intero/packages.el

;; 2. add intero, syntax-checking and auto-completion to your
;; ~/.spacemacs layer configuration & remove the haskell layer
;; if you were using that before

;; 3. make sure you have stack installed http://haskellstack.org

;; 4. fire up emacs & open up a stack project's source files
