title: Configure Rails to use different js in development and production
body: <p>I want Rails to inject different js files in development and production modes.</p>
  
  <p>Example:</p>
  
  <p>Development:</p>
  
  <pre><code>&lt;script src="/javascripts/jquery.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;script src="/javascripts/myscripts.js" type="text/javascript"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Production:</p>
  
  <pre><code>&lt;script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;script src="/javascripts/myscripts.min.js" type="text/javascript"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Is it possible to achieve it in Rails 3?</p>
  
  <p>Regards,
  Alexey Zakharov</p>
