- * integers are the fraction digits for each currency, and the
- * rounding increment. The fraction digits must be an integer
- * from 0..9. If there is no rounding, the rounding incrementis
- * zero. Otherwise the rounding increment is given in units of
- * 10^(-fraction_digits). The special tag "DEFAULT" gives the
- * meta data for all currencies not otherwise listed.
