 Get URLs for multiple JS files manually:
                  </p>
                  <pre>include_js 'json2', 'application', :only_url =&gt; true&#x000A;=&gt; ['/javascripts/json2.js', '/javascripts/application.js']</pre>
                  <p>
                  Load JS files with <a href="http://labjs.com">LABjs</a> (hosted either from
                  cdnjs or your own web server, if found in <tt>public/javascripts/</tt>):
                  </p>
                  <pre># config/assets.yml:&#x000A;js:&#x000A;
