The settings dialog contains simple instructions, a pop-up menu, and a check box. The pop-up menu contains the names of all the languages in the common dictionary folder. The language that is selected here is used for the default language.
If the user changes the language in the pop-up menu and the check box is on, the Blithe Settings application sends a message to all running applications. Blithe-aware applications should react to this message by updating all necessary text.
