The default is 1.
.It Fl r Ar repeats
Repeat the binning several times, with one realization per line of output.
+.It Fl R
+Show the output as ratios (in the range [0;1]) instead of counts.
.It Fl s Ar seed
Seed the pseudo-random number generator with this value, which is used
to generate reproducable binning.
