Has anyone used FITPACK (spline fitting by Dierckx)?

In 1987 a FORTRAN subroutine package was created that fits points to surfaces using cubic splines (though more of a subdivision scheme it appears than a parametric surface).

The author published a book (Paul Dierckx - Curve and Surface Fitting with Splines).

I'm curious:

1) If it's still useful enough to charge $100 for the book 25 years later, hasn't anyone ported it to C++?
2) Are there limitations to consider versus using Catmull Rom surfaces or NURBS?
3) Is localized control possible?

Thanks,
