""" The ``distro`` package (``distro`` stands for Linux Distribution) provides information about the Linux distribution it runs on, such as a reliable machine-readable distro ID, or version information. It is the recommended replacement for Python's original :py:func:`platform.linux_distribution` function, but it provides much more functionality. An alternative implementation became necessary because Python 3.5 deprecated this function, and Python 3.8 will remove it altogether. Its predecessor function :py:func:`platform.dist` was already deprecated since Python 2.6 and will also be removed in Python 3.8. Still, there are many cases in which access to OS distribution information is needed. See `Python issue 1322 `_ for more information.
