Program name : '=script='  ('=bin=')

   Function : generating Gaussian random variables by Box-Muller method.

   Output to STDOUT :  
      1. The generated Gaussian random number(s).

   Output to STDERR : 
      2. The random seed used. 
      3. The sums of the generated numbers and the square of them.

   Options : 
     -m N : Mean. Default is 0.
     -d N : Standard Deviation. Default is 1.
     -v N : Variance. Default is 1. -d is given more priority.
     -. N : The decimal places after the decimal point.

     -g N : How many numbers you need. Default : 6　. "inf" can be given.
     -s N : Random seed specification. Seemingly the residual divided by 2^32 is essential.
     -l   : Outputs variables by the log normal distribution instead of the normal distribution.

     -1   : Only output the random number without other secondary information.
     -:   ; Attach serial number from 1. 
     -@ N : Waiting time in seconds (that can be spedicifed 6 digits under decimal points).
