Very good question, I often had the feeling to ask that question, but I
didn't dare ;-)

That is one of the problems,
the other problem is to know that you have to refer to "numpy" !!
I understand that it's very difficult to get a homogeneous help
on the other hand, it shouldn't be too difficult to generate some kind
where all functions from all packages in the Python directory are gathered.
So I really wonder if some one hasn't done that yet.
