When I use _ as a prefix for a class name (see also this and this), the class becomes non-public and is not displayed by pydoc:
class _DoNotShowMeInPydoc:
"""Class Documentation which is not displayed"""
That's just what I want, because this class is used only internally and is of no importance for people who use the module.
But - what if someone comes along who wants to know about the internals of my module, which are (of course) also documented. Is there a flag or an option for pydoc to display the non-public classes?
