+// IMPORTANT NOTE FOR WXWIDGETS USERS:
+// If you're a wxWidgets user and you're looking at this file to learn how to
+// structure a wxWidgets console application, then you don't have much to learn.
+// This application is used more for testing rather than as sample but
+// basically the following simple block is enough for you to start your
+// own console application:
+
+/*
