Calling pylink command line causes confusing error about pylink

[hkpeprah]

Hm, I get a different message when I do this:

$ /Users/ford/dev/square $ pylink
usage: pylink [-h] [--version] [-v]
              {emulator,info,firmware,flash,unlock,erase,license} ...
pylink: error: too few arguments

Is this on the latest version?

This seems to have popped up again on the latest 0.11.1 release on Arch Linux running Python 3.9.7. Fails in an AUR package build chroot, fails on my host system, and fails in a venv with requirements.txt installed.

Haven't had a chance to dig in to it yet, but seems to be an issue with Python 2/3 argparse as Python 2.7.18 works fine:
