How to use the watchmaker.utils.urllib.parse.urlunparse function in watchmaker

    # Handle case where path does not contain a scheme
    # i.e. '/abspath/foo' or 'relpath/foo'
    # Do not test `if parts.scheme` because of how urlparse handles Windows
    # file paths -- i.e. 'C:\\foo' => scheme = 'c' :(
    return uri.scheme if '://' in urllib.parse.urlunparse(uri) else 'file'

def uri_from_filepath(filepath):
