/// A server which catches some runtime errors in your app.
/**
 * This server traces each request and dumps helpful info to a browser if
 * an error occurs. The errors which are acknowledged at the moment are
 * exceptions and your handler returning non-zero. You can fake an error
 * by appending 'debug=1' to the passed form variables.
 *
 * When an error is caught, details about that, the request that caused it and
 * the response (along with headers) are dumped to the client in a browser-
 * friendly way,
