/**
 * A utility program to take locale data represented as a Dart map whose keys
 * are locale names and write it into individual JSON files named by locale.
 * This should be run any time the locale data changes.
 *
 * The files are written under "data/dates", in two subdirectories, "symbols"
 * and "patterns". In "data/dates" it will also generate "localeList.dart",
 * which is sourced by the date_symbol_data... files.
