	<div class="explanation">
		<p>The <b>JavaScript Scruncher</b> tool (which makes use of the <a href="../reference/Uize.Build.Scruncher.html"><code>Uize.Build.Scruncher</code></a> module) lets you test the scrunching of JavaScript code. Paste some JavaScript into the <b>"SOURCE CODE"</b> tab and then switch to the <b>"SCRUNCHED CODE"</b> tab to see the scrunched version. Switch to the <b>"SCRUNCHER REPORT"</b> tab to see a summary of the file size savings for different facets of the scrunching operation. To start you off, the <b>"SOURCE CODE"</b> tab is set up with the contents of a Uize module. To learn more about how the scruncher works and the options available, consult the guide <a href="../guides/all-about-scrunching.html">All About Scrunching</a>.</p>
