cmdln.py https://pypi.python.org/pypi/cmdln was used in creator.py to parse image plugin options and arguments. There is no need in such a sofisticated API to do this simple task. Standard option parser optparse.OptionParser can do it just fine. Modified Creator class to work with option parser. Removed cmdln.py from the wic codebase.
