I was referring to the following bits of the subprocess module used in
the above code:
subprocess.mswindows
subprocess.STARTUPINFO()
subprocess.STARTF_USESHOWWINDOW
subprocess.SW_HIDE

none of which are mentioned in the module's docs:
http://docs.python.org/dev/py3k/library/subprocess.html

Cheers,
Chris
