VHS interesting, because you declaratively specify what you are recording and version control it. However, I quickly hit a painful limitation, viz.: if a command takes non-trivial amount of time to run, you need to hack it by using `Sleep` to wait for command output. So I'm not fully convinced to switch from asciinema.
