/**
 * ID3 XML output.

 * @author Ryan Cummins <ryan@zenmedia.co.uk>
 *
 * How to use:
 *
 * When calling this script you need to send an XML request of:
 *
 * <?xml version="1.0" encoding="ISO-8859-1"?>
 * <playlist>
 *      <request action="listMusic" directory="music" /> ** you can add multiple requests here if you want to scan more than one directory.
 * </playlist>
