#define __DEBUG_EXT_H__
// this is a dprintf wrapper
//
// there are three kinds of messages:
// flow: used to trace execution
// info: tells things that are important but not an error
// error: used if something has gone wrong
//
// common usage is
// SHOW_{FLOW,INFO,ERROR}( seriousness, format string, parameters... );
// SHOW_{FLOW,INFO,ERROR}0( seriousness, string );
//
// with
// seriousness: the smaller the more serious (0..3)
// format string, parameters: normal printf stuff
//
// to specify the module that created the message you have
// to define a string called
// DEBUG_MSG_PREFIX
// you dynamically speficify the maximum seriousness level by defining
// the following variables/macros
// debug_level_flow
// debug_level_info
// debug_level_error
//
// you _can_ statically specify the maximum seriuosness level by defining
// DEBUG_MAX_LEVEL_FLOW
// DEBUG_MAX_LEVEL_INFO
// DEBUG_MAX_LEVEL_ERRROR
//
// you _can_ ask to delay execution after each printed message
// by defining the duration (in ms) via
// DEBUG_WAIT_ON_MSG (for flow and info)
// DEBUG_WAIT_ON_ERROR (for error)
