+This sample shows how to use the common dialogs available from wxWidgets. 
+It also shows that generic implementations of common dialogs can be exchanged
+with native dialogs and can coexist in one application. The need for generic
+dialogs addition is recognized thanks to setup of below USE_*** setting. Their
+combinations reflects conditions of makefiles and project files to avoid unresolved 
+references during linking. For now some generic dialogs are added in static builds 
+of MSW, MAC and OS2
