+\section{Standard Modules \sectcode{UserDict} and \sectcode{UserList}}
+Each of these modules defines a class that acts as a wrapper around
+either dictionary or list objects.  They're useful base classes for
+your own dictionary-like or list-like classes, which can inherit from
+them and override existing methods or add new ones.  In this way one
+can add new behaviours to dictionaries or lists.

+The \code{UserDict} module defines the \code{UserDict} class:
+
+\begin{funcdesc}{UserDict}{}
+Return a class instance that simulates a dictionary.  The instance's
+contents are kept in a regular dictionary, which is accessible via the
+\code{data} attribute of \code{UserDict} instances.
+\end{funcdesc}
+
+\renewcommand{\indexsubitem}{(in module UserList)}
+The \code{UserList} module defines the \code{UserList} class:
+
+\begin{funcdesc}{UserList}{\optional{list}}
+Return a class instance that simulates a list.  The instance's
+contents are kept in a regular list, which is accessible via the
+\code{data} attribute of \code{UserList} instances.  The instance's
+contents are initially set to c copy of \var{list}, defaulting to the
+empty list \code{[]}.  \var{list} can be either a regular Python list,
+or an instance of \code{UserList} (or a subclass).
