+\section{\module{pkgutil} ---
+ Package extension utility}

+\versionadded{2.3}
+
+\begin{notice}[warning]
+ This is an experimental module. It may be withdrawn or completely
+ changed up to an including the release of Python 2.3 beta 1.
+\end{notice}
+
+This module provides a single function:
+
+\begin{funcdesc}{extend_path}{path, name}
+ Extend the search path for the modules which comprise a package.
+ Intended use is to place the following code in a package's
+ \file{__init__.py}:
+
+\begin{verbatim}
+from pkgutil import extend_path
+__path__ = extend_path(__path__, __name__)
+\end{verbatim}
+
+ This will add to the package's \code{__path__} all subdirectories of
+ directories on \code{sys.path} named after the package. This is
+ useful if one wants to distribute different parts of a single
+ logical package as multiple directories.
+
+ It also looks for \file{*.pkg} files beginning where \code{*}
+ matches the \var{name} argument. This feature is similar to
+ \file{*.pth} files (see the \refmodule{site} module for more
+ information), except that it doesn't special-case lines starting
+ with \code{import}. A \file{*.pkg} file is trusted at face value:
+ apart from checking for duplicates, all entries found in a
+ \file{*.pkg} file are added to the path, regardless of whether they
+ exist the filesystem. (This is a feature.)
+
+ If the input path is not a list (as is the case for frozen
+ packages) it is returned unchanged. The input path is not
+ modified; an extended copy is returned. Items are only appended
+ to the copy at the end.
+
+ It is assumed that \code{sys.path} is a sequence. Items of
+ \code{sys.path} that are not (Unicode or 8-bit) strings referring to
+ existing directories are ignored. Unicode items on \code{sys.path}
+ that cause errors when used as filenames may cause this function to
+ raise an exception (in line with \function{os.path.isdir()} behavior).
+\end{funcdesc}
