31 *
32 * ValidateISO4217 is a tool to detect differences between the latest ISO 4217
33 * data and and Java's currency data which is based on ISO 4217.
34 * If there is a difference, the following file which includes currency data
35 * may need to be updated.
36 * src/share/classes/java/util/CurrencyData.properties
37 *
38 * ############################################################################
39 *
40 * 1) Make a golden-data file.
41 * From BSi's ISO4217 data (TABLE A1.doc), extract four (or eight, if currency is changing)
42 * fields and save as ./tablea1.txt.
43 * <Country code>\t<Currency code>\t<Numeric code>\t<Minor unit>[\t<Cutover Date>\t<new Currency code>\t<new Numeric code>\t<new Minor unit>]
44 * The Cutover Date is given in SimpleDateFormat's 'yyyy-MM-dd-HH-mm-ss' format in the GMT time zone.
45 *
46 * 2) Compile ValidateISO4217.java
47 *
48 * 3) Execute ValidateISO4217 as follows:
49 * java ValidateISO4217
