"""
Compatibility stub for the stdlib 'telnetlib' module.

Python 3.13+ on some platforms may not include the 'telnetlib' module or it may
be removed/deprecated. Some projects (like napalm) import telnetlib at module
import time even when Telnet functionality is optional. To avoid ImportError
during test collection or import-time, provide a minimal stub module here.

This stub does NOT provide a full telnet implementation. If code actually
attempts to use Telnet functionality under Python versions without stdlib
telnetlib, an informative RuntimeError will be raised.

This file is intentionally small and conservative to cause minimal behavior
change while fixing import-time errors.
