Announcement text: 
----------------------------------------------------------------------
A small package of macros for creating cubic spline interpolants in 
Metapost or metafont. Given a list of points they can produce a closed 
or a relaxed spline joining them. Given a list of function values y_j 
at x_j, it can produce the graph of a cubic spline interpolating 
function y=f(x), which is either periodic or relaxed.
