chrome/test/pyautolib should not refer to chrome/test/functional. This indicates
a layering violation

[yihongg, 2012/08/08 01:04:48]

This is to construct a bash script which contains suid-python mock_pref_pane.py
to replace the actual pref_pane script on mac. I think this is fine. Please let
me know if I misunderstand anything.

main() -> Main()

main is unusually long. Please refactor it to a set of classes per platform and
a base abstract class. The derived classes carry the implementation for that
platform.

[yihongg, 2012/08/08 01:04:48]

Put the majority code in ChromotingHelper and used XXXMac and XXXWindows to
differentiate things that have to be done on different platforms.

on all platforms?

[yihongg, 2012/08/08 01:04:48]

Currently mainly mac and windows. install/uninstall/replace pref pane apply on
mac. install/uninstall apply on windows.

The flow is too difficult to follow. Please refer to the refactoring comment in
