Add console script and -m starter for command-line usage

Hope this is helpful, it was the one piece missing for me.

I don’t have a problem, but for curiosity, what is the use case? If you’re using the shell, you should know what that shell is. If this is for a script, the script should declare that too…?

Ah yes, but... I may have another script running that calls a shell command to find its shell (e.g. via subprocess.run(shell=True)); and that command has been missing in my toolbox so far, but could be shellingham (or a Python environment with the library installed, via -m). I can pick up the stdout and do my thing. This kind of stuff happens all the time in my work!
