# Diehard Craps Test\n\
# This is the CRAPS TEST. It plays 200,000 games of craps, finds \n\
# the number of wins and the number of throws necessary to end \n\
# each game. The number of wins should be (very close to) a \n\
# normal with mean 200000p and variance 200000p(1-p), with \n\
# p=244/495. Throws necessary to complete the game can vary \n\
# from 1 to infinity, but counts for all>21 are lumped with 21. \n\
# A chi-square test is made on the no.-of-throws cell counts. \n\
# Each 32-bit integer from the test file provides the value for \n\
# the throw of a die, by floating to [0,1), multiplying by 6 \n\
# and taking 1 plus the integer part of the result. \n\
