| * recalculated. It's an optimization Excel uses to determine if it |
| * needs to recalculate the spreadsheet when it's opened. So far, only |
| * the two engine ids {@code 0x80 0x38 0x01 0x00} |
| * and {@code 0x60 0x69 0x01 0x00} have been seen. |
| * A value of {@code 0x00} will cause Excel to recalculate |
| * all formulas on the next load.<p> |
