* ############################################################################
*
*  ValidateISO4217 is a tool to detect differences between the latest ISO 4217
*  data and Java's currency data which is based on ISO 4217.
*  If there is a difference, the following file which includes currency data
*  may need to be updated.
*      src/share/classes/java/util/CurrencyData.properties
*
* ############################################################################
*
* 1) Make a golden-data file.
*      From BSi's ISO4217 data (TABLE A1.doc), extract four (or eight, if currency is changing)
*      fields and save as ./tablea1.txt.
*        <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>]
*      The Cutover Date is given in SimpleDateFormat's 'yyyy-MM-dd-HH-mm-ss' format in the GMT time zone.
*
* 2) Compile ValidateISO4217.java
*
* 3) Execute ValidateISO4217 as follows:
*      java ValidateISO4217
