 /** Trivial demo for the bck2brwsr project. First of all start

  * with <a href="TestPage.html">your XHTML page</a>. Include there

  * a script that will <em>boot Java</em> in your browser.

  * <p>

  * Then use <code>@Page</code> annotation to 

  * generate a Java representation of elements with IDs in that page.

  * Depending on the type of the elements, they will have different 

  * methods (e.g. <code>PG_TITLE</code> has <code>setText</code>, etc.).

  * Use <code>@OnClick</code> annotation to associate behavior

  * with existing elements. Use the generated elements

  * (<code>PG_TITLE</code>, <code>PG_TEXT</code>) to modify the page.

  * <p>

  * Everything is type-safe. As soon as somebody modifies the page and

  * removes the IDs or re-assigns them to wrong elements. Java compiler

  * will emit an error.

  * <p>

  * Welcome to the type-safe HTML5 world!
