-# Class Date supplies date objects that support date arithmetic.
-#
-# Date(month,day,year) returns a Date object.  An instance prints as,
-# e.g., 'Mon 16 Aug 1993'.
-#
-# Addition, subtraction, comparison operators, min, max, and sorting
-# all work as expected for date objects:  int+date or date+int returns
-# the date `int' days from `date'; date+date raises an exception;
-# date-int returns the date `int' days before `date'; date2-date1 returns
-# an integer, the number of days from date1 to date2; int-date raises an
-# exception; date1 < date2 is true iff date1 occurs before date2 (&
-# similarly for other comparisons); min(date1,date2) is the earlier of
-# the two dates and max(date1,date2) the later; and date objects can be
-# used as dictionary keys.
-#
-# Date objects support one visible method, date.weekday().  This returns
-# the day of the week the date falls on, as a string.
-#
-# Date objects also have 4 read-only data attributes:
-#   .month  in 1..12
-#   .day    in 1..31
-#   .year   int or long int
-#   .ord    the ordinal of the date relative to an arbitrary staring point
-#
-# The Dates module also supplies function today(), which returns the
-# current date as a date object.
-#
-# Those entranced by calendar trivia will be disappointed, as no attempt
-# has been made to accommodate the Julian (etc) system.  On the other
-# hand, at least this package knows that 2000 is a leap year but 2100
-# isn't, and works fine for years with a hundred decimal digits <wink>.
