// Error handling routines. //
// //
// This file defines a number of global error handling routines: //
// Warning(), Error(), SysError() and Fatal(). They all take a //
// location string (where the error happened) and a printf style format //
// string plus vararg's. In the end these functions call an //
// errorhanlder function. By default DefaultErrorHandler() is used. //
// //
