It probably means that one object (A) contains another object (B).
When you call certain methods on object A, those methods call methods
in B, and return B's results to A's caller.

>From that docstring:

A.__call__() will run B()
A.__cmp__(C) will run cmp(B, C)

etc.

In other words python code which runs A() will be running the
equivalent of A.B(), where A can do other things besides calling B()
if it wants to.
