+\section{Built-in Module \sectcode{ni}}
+\label{module-ni}
+\bimodindex{ni}
+
+The \code{ni} module defines a new importing scheme, which supports
+packages containing several Python modules.  To enable package
+support, execute \code{import ni} before importing any packages.  Importing
+this module automatically installs the relevant import hooks.  There
+are no publicly-usable functions or variables in the \code{ni} module.
+
+To create a package named \code{spam} containing sub-modules \code{ham}, \code{bacon} and
+\code{eggs}, create a directory \file{spam} somewhere on Python's module search
+path, as given in \code{sys.path}.  Then, create files called \file{ham.py}, \file{bacon.py} and
+\file{eggs.py} inside \file{spam}.
+
+To import module \code{ham} from package \code{spam} and use function
+\code{hamneggs()} from that module, you can use any of the following
+possibilities:
+
+\bcode\begin{verbatim}
+import spam.ham		# *not* "import spam" !!!
+spam.ham.hamneggs()
+\end{verbatim}\ecode
+%
+\bcode\begin{verbatim}
+from spam import ham
+ham.hamneggs()
+\end{verbatim}\ecode
+%
+\bcode\begin{verbatim}
+from spam.ham import hamneggs
+hamneggs()
+\end{verbatim}\ecode
+%
+\code{import spam} creates an
+empty package named \code{spam} if one does not already exist, but it does
+\emph{not} automatically import \code{spam}'s submodules.  
+The only submodule that is guaranteed to be imported is
+\code{spam.__init__}, if it exists; it would be in a file named
+\file{__init__.py} in the \file{spam} directory.  Note that
+\code{spam.__init__} is a submodule of package spam.  It can refer to
+spam's namespace as \code{__} (two underscores):
+
+\bcode\begin{verbatim}
+__.spam_inited = 1		# Set a package-level variable
+\end{verbatim}\ecode
+%
+Additional initialization code (setting up variables, importing other
+submodules) can be performed in \file{spam/__init__.py}.
