+Called by wxWidgets to create the default configuration object for the
+application. The default version creates a registry-based 
+\helpref{wxRegConfig}{wxconfigbase} class under MSW and 
+\helpref{wxFileConfig}{wxfileconfig} under all other platforms. The 
+\helpref{wxApp}{wxapp} \helpref{GetAppName()}{wxappgetappname} and 
+\helpref{GetVendorName()}{wxappgetvendorname} methods are used to determine the
+registry key or file name.
