78 * This function takes two english strings as parameters, singular and plural, as
79 * well as a count. If a localized version exists for the current language, they
80 * are used instead. Discrimination between singular and plural is done using the
81 * localized function if any or the default one. Finally, a string interpolation
82 * is performed using the count as parameter.
