+    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
+    characters not allowed in the environment variables names, such as periods
+    and dashes, should be replaced with underscores. E.g. to define a system
+    option "foo-bar" you need to define the environment variable "wx_foo_bar".

+        and can be changed by overriding wxApp::OnAssertFailure() but setting
+        this option allows to change it without modifying the program code and
+        also applies to asserts which may happen before the wxApp object
+        creation or after its destruction.
