+ * <p/>
+ * <p/>
+ * <b>Features + limitations: </b>
+ * <ul>
+ * <p/>
+ * <li>Only one Java file</li>
+ * <li>Java 5 compatible</li>
+ * <li>Released as open source, Modified BSD licence</li>
+ * <li>No fixed config files, logging, authorization etc. (Implement yourself if you need them.)</li>
+ * <li>Supports parameter parsing of GET and POST methods (+ rudimentary PUT support in 1.25)</li>
+ * <li>Supports both dynamic content and file serving</li>
+ * <li>Supports file upload (since version 1.2, 2010)</li>
+ * <li>Supports partial content (streaming)</li>
+ * <li>Supports ETags</li>
+ * <li>Never caches anything</li>
+ * <li>Doesn't limit bandwidth, request time or simultaneous connections</li>
+ * <li>Default code serves files and shows all HTTP parameters and headers</li>
+ * <li>File server supports directory listing, index.html and index.htm</li>
+ * <li>File server supports partial content (streaming)</li>
+ * <li>File server supports ETags</li>
+ * <li>File server does the 301 redirection trick for directories without '/'</li>
+ * <li>File server supports simple skipping for files (continue download)</li>
+ * <li>File server serves also very long files without memory overhead</li>
+ * <li>Contains a built-in list of most common mime types</li>
+ * <li>All header names are converted lowercase so they don't vary between browsers/clients</li>
+ * <p/>
+ * </ul>
+ * <p/>
+ * <p/>
+ * <b>How to use: </b>
