$ histo -h
usage: histo [-h] [-b [num_bins]] [-f [l/s/n]] [-o [1/0]] [-x [n/e/u]]
[infile]
quick cmd-line histogram plotter
positional arguments:
infile input file object
optional arguments:
-h, --help show this help message and exit
-b [num_bins] number of bins
-f [l/s/n] nonlinear transf to apply (l = log, s = sqrt, n = negative
reciprocal)
-o [1/0] omit header row (ignored in demo mode)
-x [n/e/u] run with demo data (n = normal, e = exp, u = unif)
