 ;;; Commentary:
 
-;; Support for evaluating clojure code, relies either on Slime or
-;; on Nrepl.el for all eval.
+;; Support for evaluating clojure code
 
 ;; Requirements:
 
 ;; - clojure (at least 1.2.0)
 ;; - clojure-mode
-;; - either cider or nrepl.el or SLIME
+;; - either cider or SLIME
 
-;; For cider, see https://github.com/clojure-emacs/cider
+;; For Cider, 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: http://technomancy.us/126
 
-;; For nREPL:
-;; get clojure with https://github.com/technomancy/leiningen
-;; get nrepl from MELPA (clojure-mode is a dependency).
