This page is incredibly useful, but Eric stopped maintaining it in 1999!
I wonder if any enterprising good-willed people reading this list might
consider contacting Eric and taking over its maintenance.

But how do I get this JHU library? All I can see are the headers for

Here is a link with some good explanations and code samples:

Alternatively, you could use Ray Sterner's SUNALTAZI procedure from the
