W3TPL/sysdata

About
"Sysdata" syntax is a way of accessing various bits of information provided by the system under different circumstances. Any value prefixed with "@" will be treated as a reference to system data (yes, there are potential conflicts with this form... working on that; they are resolvable).

 * .url: URL for the page
 * @row: information about the current data row
