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