The module pkgutil has no documentation of functions added after its
introduction, in the official python documentation collection.

http://docs.python.org/dev/py3k/library/pkgutil.html

The module is well documented with docstrings.

I assume the module's exposed functions, some very useful, are open for
public use, for example pkgutil.iter_modules and .walk_packages.

Is all that is required copying the docstrings into the documentation?
If someone believes only Python insight and knowledge of reST sytax is
enough to make some passable documentation from the existing docstrings,
I could submit a patch for that.
