-    By default, the number of colors if 6.  You may specify a
-    value of between 1 and 15 colors.  See the author's notes

-    This program plays mastermind, if you call it by a name ending by
-    'd', otherwise it _solves_ mastermind. Call it without parameters
-    to use 6 digits (colors), or indicate the number of possible digits
-    (you cannot change the number of positions so easily).
+This program plays mastermind, if you call it by a name ending by

-    The number in parentheses is the number of possible combinations,
-    based on previous questions and answers.  If you solve the puzzle,
-    "(1)" indicates that your previous moves are enough to give correct
-    answer.  If the program acts as solver and terminates prematurely,
-    it means that you have mistaken in your answers to its guesses.
-    Question marks indicate the number of digits you have to enter
-    (either 4 when you guess or 2 when computer guesses).

-    Note that the program uses the same code for both player and
-    solver, and the only place where it makes difference is the
-    interactive part. Many obfuscations have been made to achieve
-    this.  An expression giving (bulls * 16 + cows) from two numbers
-    is, however, quite straightforward :-) , as well as the arithmetic
-    of binary coded colors-base numbers is.
