Well, if there's enough popular demand I could certainly bring the -cd patches up to date (there have been a few more) and we could get Karl's module working right - the real question is whether the output is enough better from PGPLOT. I've certainly been using PGPLOT for a long time, but I tend to draw over the cheesy Hershey font labels before publication. When Derek was still a graduate student he produced some absolutely phenomenal publication-ready output from Plplot, but I am increasingly shamed that I haven't yet learned how to do that.
