2. The progress bar imitation of linux, modify the reference to some blog, the invasion deleted
3. Other comments, like barrage of reptile-related code in the https://github.com/teleJa/bilibili
4. sys.argv determine that place because some reptiles call the document, if you feel no connection, direct transfer into the video designation on it
