"""Run Manual Test Bisect Tool
An example usage:
tools/run-bisect-manual-test.py -g 201281 -b 201290
On Linux platform, follow the instructions in this document
https://code.google.com/p/chromium/wiki/LinuxSUIDSandboxDevelopment
to setup the sandbox manually before running the script. Otherwise the script
fails to launch Chrome and exits with an error.
This script serves a similar function to bisect-builds.py, except it uses
the bisect_perf_regression.py. This means that that it can obtain builds of
Chromium for revisions where builds aren't available in cloud storage.
