    \brief The QRomanCalendar class is a shared base for calendars based on the
    ancient Roman calendar.

    \section1

    Calendars based on the ancient Roman calendar share the names of months,
    whose lengths depend in a common way on whether the year is a leap
    year. They differ in how they determine which years are leap years.
