title: How to change Clojure or Lein's Clojure default version?
body: <p>I'm not sure why but when I enter the REPL through <code>$ clojure</code> or <code>$ lein repl</code>, <code>&gt;(clojure-version)</code> says '1.2.1'. I want it to say '1.5'.</p>
  
  <p>Version 1.5 works fine in my projects managed by lein. I just want to tell lein to always use 1.5 by default, instead of 1.2.</p>
