[PATCH 07/10] perf/trace/scripting: don't show script start/stop messages by default

From: Arnaldo Carvalho de Melo
Date: Mon May 10 2010 - 18:57:11 EST


From: Tom Zanussi <tzanussi@xxxxxxxxx>

Only print the script start/stop messages in verbose mode - users
normally don't care and it just clutters up the output.
