[tdegeus]

Describe the bug

I have a Python module generated with pybind11. Because of reasons I am from to have GooseFEM/__init__.py

from ._GooseFEM import

with my entire module in _GooseFEM.

This works fine, also for .. automodule::, but the the output of

.. autosummary::
   :recursive:

   GooseFEM

is empty
