+    System options can be set by the program itself using SetOption() method
+    and they also can be set from the program environment by defining an
+    environment variable @c wx_option to set the given option for all wxWidgets
+    applications or @c wx_appname_option to set it just for the application
+    with the given name (as returned by wxApp::GetAppName()). Notice that any
