+
+	- trace: pretty printed trace output in a single column
+	- trace_fields: fields in tracepoints in separate columns

+	field will be shown only for the event has the field.  The event name
+	supports substring match so user doesn't need to specify full subsystem

+	So '%1' is the first event, '%2' is the second, and so on.
+
+	The field name can have '/raw' suffix which disables pretty printing
+	and shows raw field value like hex numbers.  The --raw-trace option
