 If writing support code in C isn't enough, it is also possible to write code in
 Python.  This code gets inserted in to the <tt>.py</tt> file created by SWIG.   One
 use of Python code might be to supply a high-level interface to certain functions.

 soon enough.  For now, think of this example as an illustration of
 what can be done without having to rely on any of the more advanced
 customization features.
 
+<p>Sometimes you may want to replace or modify the wrapper function
+that SWIG creates in the proxy <tt>.py</tt> file.  The Python module
+in SWIG provides some features that enable you do do this.  First, to
+entirely replace a proxy function you can use
+<tt>%feature("shadow")</tt>.  For example:
+
+<blockquote>
+<pre>
+%module example
+%rename(bar_id) bar(int,double);
+
+// Rewrite bar() to allow some nice overloading
+
+%feature("shadow") Foo::bar(int) %{
+def bar(*args):
+    if len(args) == 3:
+         return apply(examplec.Foo_bar_id,args)
+    return apply(examplec.Foo_bar,args)
+%}
+    
+class Foo {
+public:
+    int bar(int x);
+    int bar(int x, double y);
+}
+</pre>
+</blockquote>
+
+
+Often the proxy function created by SWIG is fine, but you simply want
+to add code to it without touching the rest of the generated function
+body.  For these cases SWIG provides the "pythonprepend" and
+"pythonappend" features which do exactly as their names suggest.  The
+"pythonprepend" feature will insert its value at the begining of the
+proxy function, and "pythonappend" will insert code at the end of the
+proxy, just before the return statement.

+<H2><a name="Python_nn65"></a>26.10 Docstring Features</H2>
+
+Usign docstrings in Python code is becoming more and more important
+ans more tools are coming on the scene that take advantage of them,
+everything from full-blown documentaiton generators to class browsers
+and popup call-tips in Python-aware IDEs.  Given the way that SWIG
+generates the proxy code by default, your users will normally get
+something like <tt>"function_name(*args)"</tt> in the popup calltip of
+their IDE which is next to useless when the real function prototype
+might be something like this:
+
+<blockquote>
+<pre>
+bool function_name(int x, int y, Foo* foo=NULL, Bar* bar=NULL);
+</pre>
+</blockquote>
+
+The features described in this section make it easy for you to add
+docstrings to your modules, functions and methods that can then be
+used by the various tools out there to make the programming experience
+of your users much simpler.
+
+
+<H3><a name="Python_nn66"></a>26.10.1 Module docstring</H3>
+
+Python allows a docstring at the begining of the <tt>.py</tt> file
+before any other statements, and it is typically used to give a
+general description of the entire module.  SWIG supports this by
+setting an option of the <tt>%module</tt> directive.  For example:
+
+<blockquote>
+<pre>
+%module(docstring="This is the example module's docstring") example
+</pre>
+</blockquote>
+
+When you have more than just a line or so then you can retain the easy
+readability of the <tt>%module</tt> directive by using a macro.  For
+example:
+
+<blockquote>
+<pre>
+%define DOCSTRING
+"The `XmlResource` class allows program resources defining menus, 
+layout of controls on a panel, etc. to be loaded from an XML file."
+%enddef
+
+%module(docstring=DOCSTRING) xrc
+</pre>
+</blockquote>
+
+
+<H3><a name="Python_nn67"></a>26.10.2 %feature("autodoc")</H3>
+
+As alluded to above SWIG will generate all the function and method
+proxy wrappers with just "*args" (or "*args, **kwargs" if the -keyword
+option is used) for a parameter list and will then sort out the
+individual parameters in the C wrapper code.  This is nice and simple
+for the wrapper code, but makes it difficult to be programmer and tool
+friendly as anyone looking at the <tt>.py</tt> file will not be able
+to find out anything about the parameters that the fuctions accept.
+
+<p>But since SWIG does know everything about the fucntion it is
+possible to generate a docstring containing the parameter types, names
+and default values. Since many of the doctring tools are adopting a
+standard of recognizing if the first thing in the docstring is a
+function prototype then using that instead of what they found from
+introspeciton, then life is good once more.
+
+<p>SWIG's Python module provides support for the "autodoc" feature,
+which when attached to a node in the parse tree will cause a docstring
+to be generated that includes the name of the funciton, parameter
+names, default values if any, and return type if any. There are also
+three options for autodoc controlled by the value given to the
+feature, described below.
+
+<H4>%feature("autodoc", "0")</H4>
+
+When the "0" option is given then the types of the parameters will
+<em>not</em> be included in the autodoc string.  For example, given
+this function prototype:
+
+<blockquote>
+<pre>
+%feature("autodoc", "0");
+bool function_name(int x, int y, Foo* foo=NULL, Bar* bar=NULL);
+</pre>
+</blockquote>
+
+Then Python code like this will be generated:
+
+<blockquote>
+<pre>
+def function_name(*args, **kwargs):
+    """function_name(x, y, foo=None, bar=None) -> bool"""
+    ...
+</pre>
+</blockquote>
+
+
+<H4>%feature("autodoc", "1")</H4>
+
+When the "1" option is used then the parameter types <em>will</em> be
+used in the autodoc string.  In addition, an atempt is made to
+simplify the type name such that it makes more sense to the Python
+user.  Pointer, reference and const info is removed,
+<tt>%rename</tt>'s are evaluated, etc.  (This is not always
+successful, but works most of the time.  See the next section for what
+to do when it doesn't.)  Given the example above, then turning on the
+parameter types with the "1" option will result in Python code like
+this:
+
+<blockquote>
+<pre>
+def function_name(*args, **kwargs):
+    """function_name(int x, int y, Foo foo=None, Bar bar=None) -> bool"""
+    ...
+</pre>
+</blockquote>
+
+
+
+<H4>%feature("autodoc", "docstring")</H4>
+
+Finally, there are times when the automatically generated autodoc
+string will make no sense for a Python programmer, particularly when a
+typemap is involved.  So if you give an explicit value for the autodoc
+feature then that string will be used in place of the automatically
+generated string.  For example:
+
+<blockquote>
+<pre>
+%feature("autodoc", "GetPosition() -> (x, y)") GetPosition;
+void GetPosition(int* OUTPUT, int* OUTPUT);
+</pre>
+</blockquote>
+
+
+<H3><a name="Python_nn68"></a>26.10.3 %feature("docstring")</H3>
+
+In addition to the autodoc strings described above, you can also
+attach any arbitrary descriptive text to a node in the parse tree with
+the "docstring" feature.  When the proxy module is generated then any
+docstring associated with classes, function or methods are output.
+If an item already has an autodoc string then it is combined with the
+docstring and they are output together.  If the docstring is all on a
+single line then it is output like this::
+
+<blockquote>
+<pre>
+"""This is the docstring"""
+</pre>
+</blockquote>
+
+Otherwise, to aid readability it is output like this:
+
+<blockquote>
+<pre>
+"""
+This is a multi-line docstring
+with more than one line.
+"""
+</pre>
+</blockquote>
+
+<H2><a name="Python_nn70"></a>26.11 Python Packages</H2>
+
+Using the <tt>package</tt> option of the <tt>%module</tt> directive
+allows you to specify what Python package that the module will be
+living in when installed. 
+
+<blockquote>
+<pre>
+%module(package="wx") xrc
+</pre>
+</blockquote>
+
+This is useful when the <tt>.i</tt> file is <tt>%import</tt>ed by
+another <tt>.i</tt> file.  By default SWIG will assume that the
+importer is able to find the importee with just the module name, but
+if they live in separate Python packages then that won't work.
+However if the importee specifies what its package is with the
+<tt>%module</tt> option then the Python code generated for the
+importer will use that package name when importing the other module
+and also in base class declarations, etc. if the pacakge name is
+different than its own.
