Subject: [PATCH 4/7] perf scripts: Export a find_scripts() function
Date: Mon,  3 Sep 2012 16:14:30 +0800	[thread overview]
Message-ID: <1346660073-20279-5-git-send-email-feng.tang@intel.com> (raw)
In-Reply-To: <1346660073-20279-1-git-send-email-feng.tang@intel.com>

So that other perf commands/browser has a way to dig out the available
scripts info in system, this is a preparation for the script browser.
