31.     --  Gtk_Calendar is a widget that displays a calendar, one month at a time. It

32.     --  can be created with Gtk_New.

33.     --

34.     --  The month and year currently displayed can be altered with Select_Month.

35.     --  The exact day can be selected from the displayed month using Select_Day.

36.     --

37.     --  The way in which the calendar itself is displayed can be altered using

38.     --  Display_Options.

39.     --

40.     --  The selected date can be retrieved from a Gtk_Calendar using Get_Date.

41.     --

42.     --  If performing many 'mark' operations, the calendar can be frozen to

43.     --  prevent flicker, using Freeze, and 'thawed' again using Thaw.
