+# Acey Ducey
+#
+# From: BASIC Computer Games (1978)
+#       Edited by David Ahl
+#
+# "This is a simulation of the Acey Ducey card game.
+#  In the game, the dealer (the computer) deals two
+#  cards face up.  You have an option to bet or not to
+#  bet depending on whether or not you feel the next
+#  card dealt will have a value between the first two.
+#
+# "Your initial money is set to $100. The game keeps
+#  going on until you lose all your money or interrupt
+#  the program.
+#
+# "The original BASIC program author was Bill Palmby
+#  of Prairie View, Illinois."
+#
+# Ruby port by Christopher Oezbek, 2021
+#
+# This uses the following techniques:
+#
+#  - The programm largely consists of a GAME LOOP,
+#    which is used to represent one round.
+#  - The Kernel function rand(Range) is used to get an
+#    Integer in the (inclusive) Range of 2 to 14.
+#  - To ensure the user enters a proper Integer
+#    via the console, an inline 'rescue' statement is
+#    used.
+#  - To capture the long text in the introduction, a
+#    squiggly HEREDOC string declaration <<~ is used.
