12/// A server which catches some runtime errors in your app.
13/**
14 * This server traces each request and dumps helpful info to a browser if
15 * an error occurs. The errors which are acknowledged at the moment are
16 * exceptions and your handler returning non-zero. You can fake an error
17 * by appending 'debug=1' to the passed form variables.
18 *
19 * When an error is caught, details about that, the request that caused it and
20 * the response (along with headers) are dumped to the client in a browser-
21 * friendly way, 
22 *
