When I made the first pre command script, I opted to use a class to
represent the unattended install setup, and other pre commands followed
this style. Since the code is small, I see no problem in putting it
under __main__ altogether. So Jason, you can remove the code from the
class and put it under __main__, please.

Other than the issues pointed out, looks good.
