| * A class encapsulating a currency, as defined by ISO 4217. A |
| * <tt>Currency</tt> object can be created given a <tt>Locale</tt> or |
| * given an ISO 4217 code. Once created, the <tt>Currency</tt> object |
| * can return various data necessary to its proper display: |

| * <li>The number of fraction digits to display |
| * <li>A rounding increment |
