py2exe functions

For those who don't want to figure out how to use py2exe use the following functions:

def main_is_frozen():
    '''main_is_frozen() returns True when running the exe, and False when running from a script. '''
    import sys, imp
    return (hasattr(sys, "frozen") or # new py2exe
             hasattr(sys, "importers") # old py2exe
             or imp.is_frozen("__main__")) # tools/freeze

def create_exe():
    '''If not an exe then create a single file exe from current script file'''
    if main_is_frozen() == False:
        from distutils.core import setup
        import py2exe, sys

        sys.argv = [sys.argv[0], 'py2exe']

        setup(
              console=[sys.argv[0]],
              zipfile = None,
              options = {
                        'py2exe':{
                                   'bundle_files': 1,
                                   'optimize' : 2,
                                   'compressed' : True
                                 }
                        }
             )
