 /**
  * 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. More realistic
  * examples might read the data from files or over the web, which uses the
  * same APIs but requires different imports.
  *
  * 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.
