+// Definitions for the Roman calendar
+// TODO The 5.5.1 gedcom spec mentions this calendar, but gives no details of
+// how it is to be represented....  This class is just a place holder so that
+// webtrees won't compain if it receives one.
+//
+// NOTE: Since different calendars start their days at different times, (civil
+// midnight, solar midnight, sunset, sunrise, etc.), we convert on the basis of
+// midday.
