Attached is complete source for the old cubic spline interpolation
package. Dick Valent was able to dig this up. The package has seven
routines: coeff1, terp1, coeff2, terp2, trip, search, interp. All of
these are part of the HLU distribution, except for coeff2 and terp2.

If you want to stay current, in place of using the cubic spline package,
I would recommend using the more recent functions documented in
the Fitgrid package at:
