Subject: [PATCH 3/3] Use entry_points instead of scripts

As decribed in https://click.palletsprojects.com/en/7.x/setuptools/ shebangs only work in
unix and OSX (and in cygwin on windows). By using the entry_points mechanism
Python will handle all cross-platform issues making it useable for everybody.
