**-h**, **--help**

        Print the monitor's options and the available reactors list.

**-r**, **--reactor** *reactor*

        Enables the *reactor*. See **-h** for a list of available reactors.

**-s**, **--self**

        When tracing (**-t**), also print the events that happened during the **rv**
        command itself. If the **rv** command itself generates too many events,
        the tool might get busy processing its own events only.

**-t**, **--trace**

        Trace monitor's events and error.

**-v**, **--verbose**

        Print debug messages.
