	// This is a hack to enable google-code-prettify to work with maven.
	//
	// The problem is that maven, when building the site, replaces:
	// <pre class="prettyprint">...</pre>
	// with:
	// <div class="prettyprint"><pre>...</pre></div>
	//
	// Effectively, it removes the class parameter from the <pre> element, which
	// is required for google-code-prettify to work.
	// 
	// This hack restores the class of all <pre> elements which are the child of 
	// a <div class="prettyprint">.
	//
