title: Using jsx command-line compiler -- won't compile to file
body: <p>I have what is probably a simple jsx question, so please forgive my stupidity.</p>
  
  <p>I'm playing with React's jsx command-line compiler. I have a VERY simple JSX file that looks like this:</p>
  
  <pre><code>var helloWorld = React.createClass({
      render: function() {
          return &lt;div&gt;hello&lt;/div&gt;
      }
  })
  </code></pre>
  
  <p>If I type the following in the command-line, it compiles (and shows me the result in the console): <code>jsx test.jsx</code></p>
  
  <p>I want to output this file to <code>test.js</code>. But if I try the command <code>jsx test.jsx test.js</code> nothing happens -- it only outputs the help information for the <code>jsx</code> command.</p>
  
  <p>Any ideas? I feel like it should be obvious.</p>
