@ -22,6 +22,10 @@ Display the help and exit.
Set the window geometry. If a parameter is omitted it's filled with the default value.
=item B<-m> I<monitor>B<:>I<monitor>B<:>I<...>
Set monitors to be used and in what order. Positive numeric arguments only, separated by colons.
=item B<-b>
Dock the bar at the bottom of the screen.
