+/**
+ * The Minguo calendar system.
+ *
+ * This chronology defines the rules of the Minguo calendar system.
+ * This calendar system is primarily used in the Republic of China, often known as Taiwan.
+ * Dates are aligned such that {@code 0001-01-01 (Minguo)} is {@code 1912-01-01 (ISO)}.
+ *
+ * The fields are defined as follows:
+ *
+ * - era - There are two eras, the current 'Republic' (ERA_ROC) and the previous era (ERA_BEFORE_ROC).
+ *
- year-of-era - The year-of-era for the current era increases uniformly from the epoch at year one.
+ * For the previous era the year increases from one as time goes backwards.
+ * The value for the current era is equal to the ISO proleptic-year minus 1911.
+ *
- proleptic-year - The proleptic year is the same as the year-of-era for the
+ * current era. For the previous era, years have zero, then negative values.
+ * The value is equal to the ISO proleptic-year minus 1911.
+ *
- month-of-year - The Minguo month-of-year exactly matches ISO.
+ *
- day-of-month - The Minguo day-of-month exactly matches ISO.
+ *
- day-of-year - The Minguo day-of-year exactly matches ISO.
+ *
- leap-year - The Minguo leap-year pattern exactly matches ISO, such that the two calendars
+ * are never out of step.
+ *
+ *
+ *
Specification for implementors
+ * This class is immutable and thread-safe.
+ *
+ * @since 1.8
