Did I request the --quiet thing?  It seems like there's a
miscommunication.. :-/

I still prefer -v option and not printing descriptions by default - but
want to inform users to use -v option.  However I also want to hear from
others on this.

Btw, it'd better if it can support event glob on the pmu events (or
simply all events) too as this will increase the number of events
significantly.  But this can be a further work.

Thanks,
Namhyung
