To add to what Steven said above, there is also options to mute/unmute channels by level (Debug/Normal/Warning/Error). You can set the overall level with the -out:level flag, which takes a numeric level (0 – fatal, 100 – error, 200 – warning, 300 – info, 400 – debug, 500 – trace). Also, in addition to the -out:mute/-out:unmute flags, there are -out:mute_warning/-out:unmute_warning and -out:unmute_error with the same syntax.
