[ghost stip (do not use), 2014/05/23 00:40:23]

it would be ideal to use
http://chrome-build-extract.appspot.com/get_builds?builder=linux_perf_bisect_...
 (fill in builder as appropriate) as it's a good mirror of what is happening on
the tryserver.

Thank you Mike,
 Can bisect bot on master4 access this site?
Where can I get more information about chrome-build-extract.appspot, I would
like to get a status of particular build not all build, is there a way to do
this?
