> bash is just fine (yes, it is)

No, it's not. It's 2020, we need to stop it with the stringly-typed, footgun-filled madness that is bash scripting. We deserve better than this.

Unless I'm missing something, this README example already contains a bug:

    template $(dirname $0)/motd.template > /etc/motd

This will fail if the script path contains a space.
