Is there an argument flag that will suppress Rosetta output? Even better, one that will suppress all but errors?
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.
Your answers are so much more complete compared to mine - I guess you're using the verbose flag...
Great, thank you both.
