;;; Commentary:

;; Support for evaluating clojure code

;; Requirements:

;; - clojure (at least 1.2.0)
;; - clojure-mode
;; - inf-clojure, cider or SLIME

;; For clojure-mode, see https://github.com/clojure-emacs/clojure-mode
;; For cider, see https://github.com/clojure-emacs/cider
;; For inf-clojure, see https://github.com/clojure-emacs/cider

;; For SLIME, the best way to install these components is by following
;; the directions as set out by Phil Hagelberg (Technomancy) on the
;; web page: https://technomancy.us/126
