How to use the greenlet.__version__ function in greenlet

def test_version(self):
        upfile = lambda p: os.path.join(os.path.dirname(__file__), "..", p)
        hversion, = re.findall('GREENLET_VERSION "(.*)"', readfile(upfile("greenlet.h")))
        sversion = readclose(os.popen("%s %s --version" % (sys.executable, upfile("setup.py")))).strip()
        self.assertFalse(sversion != hversion)
        self.assertFalse(sversion != greenlet.__version__)
