#   S(1)=U(1)+...+U(100), S2=U(2)+...+U(101),... are formed.    \n\

# sequence of independent standard normals, which are converted \n\
# to uniform variables for a KSTEST. The  p-values from ten     \n\
# KSTESTs are given still another KSTEST.                       \n\

# Note well:  -O causes the old diehard version to be run (more or\n\
# less).  Omitting it causes non-overlapping sums to be used and \n\
# directly tests the overall balance of uniform rands.\n\
