This package is an extension to the {@see java.util.prefs "Java Preferences API"}, it allows applications to store and retrieve user and system preference and configuration data, relieving Preference's requirements to specify default values.
This data is stored persistently in an implementation-dependent backing store. There are two separate trees of preference nodes, one for user preferences and one for system preferences.
The backing store implementaion is specified by the "" system property (the factory's class name, see the {@link sanscreen.system.prefs.PreferencesExtFactory}).
