74 * Tracing facilities for MIG generated stubs.
75 *
76 * At the moment, there is only a printf, which is
77 * activated through the runtime switch:
78 * 	mig_tracing to call MigEventTracer
79 * 	mig_errors to call MigEventErrors
80 * For this to work, MIG has to run with the -L option,
81 * and the mig_debug flags has to be selected
82 *
83 * In the future, it will be possible to collect infos
84 * on the use of MACH IPC with an application similar
85 * to netstat.
86 *
87 * A new option will be generated accordingly to the
88 * kernel configuration rules, e.g
89 *	#include <mig_log.h>
