"""bfos operator console — thin entry point (sh/Python polyglot).

The file is valid POSIX shell *and* valid Python:

* run as ``admin/bf`` (or as the ``bf`` symlink that
  ``admin/bf-bootstrap.sh`` creates), the shell line above checks that
  ``python3`` exists and, when it does not, prints a Turkish error and points at
  the proven bash console (``admin/bf-menu``) — a device without Python is still
  operational,
* everything after that line is the Python entry point: it puts the repository
  root on ``sys.path`` and calls :func:`bfos.cli.main`. Nothing else lives here;
  all logic is in the ``bfos`` package next to it.

Usage: sudo bfos [--full] [--dry-run] [--check] [--repo YOL] [--version] [--lang tr]
