/**
 * #GtkCalendar is a widget that displays a Gregorian calendar, one month
 * at a time. It can be created with gtk_calendar_new().
 * 
 * The month and year currently displayed can be altered with
 * gtk_calendar_select_month(). The exact day can be selected from the
 * displayed month using gtk_calendar_select_day().
 * 
 * To place a visual marker on a particular day, use gtk_calendar_mark_day()
 * and to remove the marker, gtk_calendar_unmark_day(). Alternative, all
 * marks can be cleared with gtk_calendar_clear_marks().
 * 
 * The way in which the calendar itself is displayed can be altered using
 * gtk_calendar_set_display_options().
 * 
 * The selected date can be retrieved from a #GtkCalendar using
 * gtk_calendar_get_date().
 * 
 * Users should be aware that, although the Gregorian calendar is the
 * legal calendar in most countries, it was adopted progressively
 * between 1582 and 1929. Display before these dates is likely to be
 * historically incorrect.
