gsl-histogram  is  a  demonstration  program  for  the GNU Scientific Library.  It takes three arguments,
       specifying the upper and lower bounds of the histogram and the number of bins.   It  then  reads  numbers
       from  `stdin', one line at a time, and adds them to the histogram.  When there is no more data to read it
       prints out the accumulated histogram using gsl_histogram_fprintf.  If  n  is  unspecified  then  bins  of
       integer width are used.

       Here  is  an example.  We generate 10000 random samples from a Cauchy distribution with a width of 30 and
       histogram them over the range -100 to 100, using 200 bins.

            gsl-randist 0 10000 cauchy 30 | gsl-histogram -100 100 200 > histogram.dat

       A plot of the resulting  histogram  will  show  the  familiar  shape  of  the  Cauchy  distribution  with
       fluctuations caused by the finite sample size.
