/**
 * @fileoverview
 * Registers a language handler for Clojure.
 *
 *
 * To use, include prettify.js and this file in your HTML page.
 * Then put your code in an HTML tag like
 *      <pre class="prettyprint lang-lisp">(my lisp code)</pre>
 * The lang-cl class identifies the language as common lisp.
 * This file supports the following language extensions:
 *     lang-clj - Clojure
 *
 *
 * I used lang-lisp.js as the basis for this adding the clojure specific
 * keywords and syntax.
 *
 * "Name"    = 'Clojure'
 * "Author"  = 'Rich Hickey'
 * "Version" = '1.2'
 * "About"   = 'Clojure is a lisp for the jvm with concurrency primitives and a richer set of types.'
 *
 *
 * I used <a href="http://clojure.org/Reference">Clojure.org Reference</a> as
 * the basis for the reserved word list.
