+ * Convert java DateFormat patterns into Excel custom number formats.
+ * For example, to format a date in excel using the "dd MMMM, yyyy" pattern and Japanese
+ * locale, use the following code:
+ *
+ * <pre><code>
+ * // returns "[$-0411]dd MMMM, yyyy;@" where the [$-0411] prefix tells Excel to use the Japanese locale
+ * String excelFormatPattern = DateFormatConverter.convert(Locale.JAPANESE, "dd MMMM, yyyy");
+ *
+ * CellStyle cellStyle = workbook.createCellStyle();
+ *
+ * DataFormat poiFormat = workbook.createDataFormat();
+ * cellStyle.setDataFormat(poiFormat.getFormat(excelFormatPattern));
+ * cell.setCellValue(new Date());
+ * cell.setCellStyle(cellStyle); // formats date as '2012\u5e743\u670817\u65e5'
+ *
+ * </code></pre>
