-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 a renewed alternative implementation 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 3.7 is expected to remove it
-altogether. Its predecessor function :py:func:`platform.dist` was already
-deprecated since Python 2.6 and is also expected to be removed in Python 3.7.
-Still, there are many cases in which access to OS distribution information
-is needed. See `Python issue 1322 <https://bugs.python.org/issue1322>`_ for
-more information.

-    If you have a need to get distros for reliable IDs added into this set,
-    or if you find that the :func:`distro.id` function returns a different
-    distro ID for one of the listed distros, please create an issue in the
-    `distro issue tracker`_.
-
-    **Lookup hierarchy and transformations:**
-
-    First, the ID is obtained from the following sources, in the specified

-
-    * the value of the "ID" attribute of the os-release file,

-    * the value of the "Distributor ID" attribute returned by the lsb_release
-      command,
-
-    * the first part of the file name of the distro release file,
-
-    The so determined ID value then passes the following transformations,
-    before it is returned by this method:
-
-    * it is translated to lower case,
-
-    * blanks (which should not be there anyway) are translated to underscores,
-
-    * a normalization of the ID is performed, based upon
-      `normalization tables`_. The purpose of this normalization is to ensure
-      that the ID is as reliable as possible, even across incompatible changes
-      in the OS distributions. A common reason for an incompatible change is
-      the addition of an os-release file, or the addition of the lsb_release
-      command, with ID values that differ from what was previously determined
-      from the distro release file name.
