+This patch makes a number of changes to the SWIG python module.
+
+1. Add -apply option, and change the default code output to use the
+   foo(*args, **kw) calling syntax instead of using apply().  If the
+   -apply option is given then code is generated as before.  This is
+   very similar to Patch #737281 but the new -modern option makes the
+   second half of that patch unnecessary so it is not included here.
+
+2. Add -new_repr option.  This is the same as my Patch #797002 which I
+   will mark as closed since it is no longer needed.  When this new
+   option is used then the __repr__ methods that are generated for
+   proxy classes will be more informative and give details about the
+   python class and the C++ class.
+
+3. Add %feature("addtofunc").  It allows you to insert one or more
+   lines of code inside the shadow method or function that is already
+   generated, instead of replacing the whole thing like
+   %feature("shadow") does.  For __init__ it goes at the end, for
+   __del__ it goes at the begining and for all others the code
+   generated is expanded out to be like
+
+    def Bar(*args, **kwargs):
+        val = _module.Foo_Bar(*args, **kwargs)
+        return val
+
+   and the "addtofunc" code is inserted just before the return
+   statement. If the feature is not used for a particular method or
+   function then the shorter code is generated just like before.
+
+4. A little bit of refactoring to make implementing addtofunc a little
+   easier.
+
+5. Added a -modern command-line flag that will cause SWIG to omit the
+   cruft in the proxy modules that allows it to work with versions of
+   Python prior to 2.2.  The result is a simpler, cleaner and faster
+   python proxy module, but one that requires Python 2.2 or greater.
+   For most of us this requirement is easy to live with!
+
+
+I've been using and greatly benefiting from all these features with
+wxPython for the last few weeks and have had no problems.
+
+This patch depends upon Patch #829317.
