title: How to start/stop Instruments (Time Profiler) programatically?
body: <p>Is there any way to start/stop Instruments profiling programmatically ? I need to profile just a specific section of my OS X code in a reliable way but I can't seem to find any documentation for Instruments which might tell me how I might do this. With CHUD/Shark there was a programming API and a command line tool to support this but I don't see the equivalent for Instruments anywhere ? FWIW I found some old forum posts from around 2009 bemoaning the lack of Instruments functionality in this area but nothing more recent.</p>
