'True if the name of a file implies that it is a static resource.
For Java applications specified with web.xml and appengine-web.xml, we
create a staging directory that includes a __static__ hierarchy containing
links to all files that are implied static by the contents of those XML
files. So if a file has been copied into that directory then we can assume
it is static.
Args:
filename: The full path to the file.
Returns:
True if the file should be considered a static resource based on its name.'

    static = ('__static__' + os.sep)
    return (static in filename)
