"""One-off check on the ProPresenter Mac: link a message into a playlist via a restart.

Usage (on the ProP Mac):
  /usr/bin/python3 test_restart_link.py <message-notes.pyz> "<notes title>" YYYY-MM-DD "<presentation name>"
Refuses to run if anything is on screen. Prints whether the link is in ProPresenter's
playlist file after ProPresenter is running again (and still there 60 s later).
