+# This helper function will take a wxPython object and convert it to
+# another wxPython object type. This will not be able to create objects
+# that are derived from wxPython classes by the user, only those that are
+# actually part of wxPython and directly corespond to C++ objects.
+#
+# This is useful in situations where some method returns a generic
+# type such as wxWindow, but you know that it is actually some
+# derived type such as a wxTextCtrl. You can't call wxTextCtrl specific
+# methods on a wxWindow object, but you can use this function to
+# create a wxTextCtrl object that will pass the same pointer to
+# the C++ code. You use it like this:
+#
+# textCtrl = wxPyTypeCast(window, "wxTextCtrl")
+#
+#
+# WARNING: Using this function to type cast objects into types that
+# they are not is not recommended and is likely to cause your
+# program to crash... Hard.
