I don't think anyone was suggesting there was anything secretive about it -- after all I work for NOAA too!

I just didn't see the code on a quick glance at the page. And in any case, old FORTRAN code for a few command line utilities doesn't quite satisfy the need for a library -- though I'm sure it's worth looking at and testing against.

Anyway, this all started because people ask about it a lot, and while pointing them to that page will answer the questions, it won't be as easy for folks as a C lib with a clean API -- it's not that big a deal, only a handful of functions, really.
