-This is an event handler function called when the operating system or GUI session is

-at this point.
+This virtual function is where the execution of a program written in wxWidgets
+starts. The default implementation just enters the main loop and starts
+handling the events until it terminates, either because 
+\helpref{ExitMainLoop}{wxappexitmainloop} has been explicitly called or because
