.SH DESCRIPTION
.I Rlenoise
adds uniform random noise to an image.  The peak-to-peak amplitude of
the noise can be specified with the
.B \-n
flag, the default value is 4.  This program may be
useful for trying to deal with quantization in an output device, if
you are able to trade spatial resolution for color resolution, and you
don't have a good characterization of the quantization function.
