How to use the ipwb.replay.start function in ipwb

def startReplay(warcFilename):
    global p

                              '/../samples/warcs/' + warcFilename)
    tempFilePath = tempfile.gettempdir() + '/' + ''.join(random.sample(
        string.ascii_uppercase + string.digits * 6, 12)) + '.cdxj'

    open(tempFilePath, 'a').close()  # Create placeholder file for replay

    p = Process(target=replay.start, args=[tempFilePath])
    p.start()
    sleep(5)

    cdxjList = indexer.indexFileAt(pathOfWARC, quiet=True)
    cdxj = '\n'.join(cdxjList)

    with open(tempFilePath, 'w') as f:
        f.write(cdxj)
