title: Do I have to reference TypeScript definition in every file?
body: <p>Is there a way to tell TypeScript to use a certain file (or set of files) as a definition for everything compiled?</p>
  <p>My only alternative currently is to add something like this in every single TypeScript file (which seems clunky):</p>
  <pre><code>/// &lt;reference path=&quot;DefinitelyTyped/requirejs/require.d.ts&quot; /&gt;
  </code></pre>
