2*173a3b01SDaniel Bristot de Oliveira
3*173a3b01SDaniel Bristot de Oliveira        Set the automatic trace mode. This mode sets some commonly used options
4*173a3b01SDaniel Bristot de Oliveira        while debugging the system. It is equivalent to use **-T** *us* **-s** *us*
5*173a3b01SDaniel Bristot de Oliveira        **-t**. By default, *timerlat* tracer uses FIFO:95 for *timerlat* threads,
6*173a3b01SDaniel Bristot de Oliveira        thus equilavent to **-P** *f:95*.
