I've written a python wrapper (using F2PY) that I've been using for a
few months. I just rolled it together and put it on my website at


The thing to clarify with Nocedal is the 'advertising' clause in it's
conditions of use -- this wouldn't be acceptable as a subroutine you
might not realize you're using.
