There are a couple of functions from `pathutils
<http://www.voidspace.org.uk/python/pathutils.html>`_ that do this
(originally supplied by Thomas Heller I believe) :

def main_is_frozen():
    """Return ``True`` if we're running from a frozen program."""
    import imp
    return (
        # new py2exe
        hasattr(sys, "frozen") or
        # tools/freeze
        imp.is_frozen("__main__"))

def get_main_dir():
    """Return the script directory - whether we're frozen or not."""
    if main_is_frozen():
        return os.path.abspath(os.path.dirname(sys.executable))
    return os.path.abspath(os.path.dirname(sys.argv[0]))

just call ``get_main_dir()`` and it works consistently with py2exe'd
scripts and normal scripts.

All the best,
