|Power load test now uses a pre-packed extension (extension.crx).
|Therefore, changes to the unpacked extension either on client or on server
|will not be used.
|In order to update extension.crx, use chrome's built in packer. You must close
|all chrome windows before running this command.
|Alternatively, extension developer mode will provide a
|GUI way of doing the same task.
|The extension will not automatically begin the test if run manually. Instead,
|it will attempt to load localhost:8001/testparams.html, which will not exist
|if the test isn't run with autotest.
|If running manually, click on the power_LoadTest extension icon to begin the
|test with default settings (3600 second test).
