;;; Commentary:
|
|
|
|
;;; support for evaluating clojure code, relies on slime for all eval
|
|
|
|
;;; Requirements:
|
|
|
|
;;; - clojure (at least 1.2.0)
|
|
;;; - clojure-mode
|
|
;;; - slime
|
|
|
|
;;; By far, 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
