[PATCH 2/5] perf tools: Add new perf data command
From: Jiri Olsa
Date: Wed Aug 06 2014 - 08:15:57 EST
Adding new 'perf data' command to provide operations over
data files.
The 'perf data convert' sub command is coming in following patch,
but there's possibility for other useful commands like 'perf data ls'
(to display perf data file in directory in ls style).
