gecong1973 d597dab65c Using sys.exit(main()) instead of main()
As we known, Exceptions are raised by the sys.exit() function.
When they are not handled, no stack traceback is printed in the
Python interpreter. In this patch we have known main() got return
values(eg:0, 1), but it can't specifies exit status when terminate
the main thread by unusing sys.exit(). So when using sys.exit(main())
instead of main() may be more readable and reasonable.

Mistral development environment setup is complete.
Mistral development uses virtualenv to track and manage Python dependencies

To activate the Mistral virtualenv for the extent of your current shell
session you can run:
$ source %s/bin/activate
Or, if you prefer, you can run commands in the virtualenv on a case by case
basis by running:
$ %s/tools/with_venv.sh <your command>
Also, make test will automatically use the virtualenv.
