terminal screencast

• Install with sudo pip3 install asciinema or sudo apt-get install asciinema or whatever
  
• Make a new recording and save it to a local file:
  asciinema rec {{path/to/file}}.cast
  
• Replay a terminal recording from a local file:
  asciinema play {{path/to/file}}.cast
  
• Only replay, no going backwards
