/**
 * To split a previously csv i18n file into simple i18n bundles for the locales defined in {@link #locales}.
 *
 * The order of {@link #locales} will be used to extract for each locale i18n bundle (means the order defined
 * in the csv file is not used). Make sure to use exactly the same order.
