p;        <body>
                    <script language="javascript" type="text/javascript" src="js_inline_debugger.js"></script>
                    </body>
                    </html>
    Instruction:
                    It is a simple javascript inline debugger. You must add xhtml1-transitional dtd to your
                    html document if you wanna to use the script.
