jbe@494: This function selects which layout should be used when calling slot.render_layout() (as done by request.handler(...)). If nil is selected as layout, then no layout will be used, but the slot named "data" is used plainly. The second argument to slot.set_layout is the content-type which is sent to the browser.
jbe@494: 
jbe@494: The default layout for views is "default". Actions have no default layout, but an explicit call of slot.set_layout(...) (even with nil as first argument) during request handling will cause subsequent calls of slot.layout_is_set() to return true which indicates that content (e.g. via slot.put_into("data", ...)) is available and should be rendered instead of using the action's return value to forward or redirect the user agent.
