-This represents singleton object for accessing errorStream, outStream in methods used by CLI, that do not have any reference to streams of CLI command (or CLI context) object.
+I represent an object to manage notifications to user when ran in CLI mode.
+
+I can act as the PharoLauncher default application (see PharoLauncherApplication class>>#default).
+I only have a minimal set of methods to provide some polymorphism with an SpApplication and avoid UI interactions.
