-Dropping support for legacy Python versions
--------------------------------------------
-
-To drop support for Python 2.7 up to 3.6 several steps have to be done as
-documented at https://zope.dev/developer/python2.html#how-to-drop-support.
-There is a script to ease this process.
-
-Preparation
-+++++++++++
-
-* The package to remove legacy python support from has to have a ``.meta.toml``
-  file aka it must be under control of the ``config-package.py`` script.
-
-Usage
-+++++
-
-To run the script call::
-
-    $ bin/python drop-legacy-python.py <path-to-package>
-
-Additional optional parameters, see above at ``config-package.py`` for a
-descriptions of them:
-
-* ``--branch``
-
-You can call the script interactively by passing the argument
-``--interactive``, this will let the various scripts prompt for information and
-prevent automatic commits and pushes. That way all changes can be viewed before
-committing them.
