| 70 | * At the moment, there is only a printf, which is | |
| 71 | * activated through the runtime switch: | |
| 72 | * mig_tracing to call MigEventTracer | |
| 73 | * mig_errors to call MigEventErrors | |
| 74 | * For this to work, MIG has to run with the -L option, | |
| 75 | * and the mig_debug flags has to be selected | |

| 77 | * In the future, it will be possible to collect infos | |
| 78 | * on the use of MACH IPC with an application similar | |
| 79 | * to netstat. | |
