-:mod:`UserDict` --- Class wrapper for dictionary objects
-========================================================
-
-.. module:: UserDict
-   :synopsis: Class wrapper for dictionary objects.
-
-
-The module defines a mixin,  :class:`DictMixin`, defining all dictionary methods
-for classes that already have a minimum mapping interface.  This greatly
-simplifies writing classes that need to be substitutable for dictionaries (such
-as the shelve module).
-
-This also module defines a class, :class:`UserDict`, that acts as a wrapper
-around dictionary objects.  The need for this class has been largely supplanted
-by the ability to subclass directly from :class:`dict` (a feature that became
-available starting with Python version 2.2).  Prior to the introduction of
-:class:`dict`, the :class:`UserDict` class was used to create dictionary-like
-sub-classes that obtained new behaviors by overriding existing methods or adding
-new ones.
-
-The :mod:`UserDict` module defines the :class:`UserDict` class and
-:class:`DictMixin`:
-
-
-.. class:: UserDict([initialdata])
-
-   Class that simulates a dictionary.  The instance's contents are kept in a
-   regular dictionary, which is accessible via the :attr:`data` attribute of
-   :class:`UserDict` instances.  If *initialdata* is provided, :attr:`data` is
-   initialized with its contents; note that a reference to *initialdata* will not
-   be kept, allowing it be used for other purposes.
-
-   .. note::
-
-      For backward compatibility, instances of :class:`UserDict` are not
-      iterable.
-
-
-.. class:: IterableUserDict([initialdata])
-
-   Subclass of :class:`UserDict` that supports direct iteration (e.g.  ``for key in
-   myDict``).
-
-In addition to supporting the methods and operations of mappings (see section
-:ref:`typesmapping`), :class:`UserDict` and :class:`IterableUserDict` instances
-provide the following attribute:
-
-
-.. attribute:: IterableUserDict.data
-
-   A real dictionary used to store the contents of the :class:`UserDict` class.
