2 shell scripts handle the job of generating the asciicasts.json used by the player.
They are not bulletproof, and you may need to adjust them to suit your configuration.
Currently they must be used in the root directory of a mawww/golf git clone on your machine.
Create two empty dirs xdokeys and asciicasts.
Firt run convert.sh with a vimgolf id, it will create a .sh file in the xdokeys dir.
Then run rec.sh in tmux providing the same vimgolf id. It will generate a .json file in the asciicasts dir.
