pydoc injecting python submodules content to main module

I have a module dlprim

dlprim/
  __init__.py
  netconfig.py
  _pydlprim.so

its __init__.py incldes:

from ._pydlprim import *
from .netconfig import *

where ._pydlprim is boost.pythom module and .netconfig is submodule.

If I generate a documentation with pydoc -w dlprim - it does not include classes from _pydlprim and netconfig.py so in order to generate them all I need to run pydoc -w dlprim dlprim.netconfig dlprim._pydlprim

But I get 3 separate files each in different namespace I want all of the classes to be found under dlprim module and namespace in pydoc.

How can I do it, or is there an alternative for this?
