configure leiningen to use library when repl starts

[Andy Smith]

Hi,

 total newbie here and have come unstuck with the repl configuration. How can I configure my leiningen project's clj file to call '(use 'clojure.math.numeric-tower)' when the repl is started with 'lein repl'? I have tried adding the command to the repl-options but I get a java exception when I start the repl :

(defproject test "1.0.0-SNAPSHOT"
  :description "FIXME: write description"
  :dependencies [[org.clojure/clojure "1.3.0"]
                 [org.clojure/math.numeric-tower "0.0.2"]])
  :repl-options {
                 :init (clojure.core/use 'clojure.math.numeric-tower)}

Something that works is putting ":injections [(require 'clojure.repl)]" in .lein/profiles.clj.

It works (as evidenced by (doc ...) working in "lein repl") but I don't know if that is the correct approach.
