- * This provides a basic example of internationalization usage. It uses the
- * local variant of all the facilities, meaning that libraries with the
- * data for all the locales are directly imported by the program. Once lazy
- * loading is available, we expect this to be the preferred mode, with
- * the initialization code actually loading the specific libraries needed.
- *
- * This defines messages for an English locale directly in the program and
- * has separate libraries that define German and Thai messages that say more or
- * less the same thing, and prints the message with the date and time in it
- * formatted appropriately for the locale.
