 The leftmost iterators are in the outermost for-loop, so the output tuples\n\
 cycle in a manner similar to an odometer (with the rightmost element changing\n\
 on every iteration).\n\n\
+To compute the product of an iterable with itself, specify the number\n\
+of repetitions with the optional repeat keyword argument. For example,\n\
+product(A, repeat=4) means the same as product(A, A, A, A).\n\n\
