## @deftypefnx{Function File} rolldices (@var{n}, @var{nrep}, @var{delay})
## Returns @var{n} random numbers from the 1:6 range, displaying a visual selection
## effect.
##
## @var{nrep} sets the number of rolls, @var{delay} specifies time between
## successive rolls in seconds. Default is nrep = 25 and delay = 0.1.
##
## Requires a terminal with ANSI escape sequences enabled.
