Hi Hagen,

Hmm.. maybe we can add support something like above later - "perf
download event" or "perf download blabla".

But I have a different idea - leaving perf download as a plumbing tool,
and add --download option into the perf list to call it internally.
Maybe it can automatically download event file if it didn't find the
file in the local cache.

Looks like 'event-cache' is a more appropriate name IMHO.

Anyway, thank you for the thought and suggestion. :)

Thanks,
Namhyung
