SMOOTH reads pairs of numbers (x- and y-values) from the standard input
(or the given file), fits a smooth curve to the points, and writes to
the standard output points from the smooth curve.  By default, the
curve is calculated using the "lowness" procedure developed by W.  S. 
Cleveland (see below).  This technique achieves robustness by
decreasing weights on data points which are far from the fitted line. 
An alternate procedure called "split linear smoothing" due to Art Owen
is also provided (with the -s switch).  This technique smooths the data
while preserving sharp discontinuities in slope or value.
