[Jprogramming] LBFGS addon

['Jon Hough' via Programming]

I was wondering whether the math addons contained an implementation of the LBFGS algorithm. I couldn't find anything, except this cryptic
entry in the wiki:
http://code.jsoftware.com/wiki/Addons/math/lbfgs

Looking through the math addon files I couldn't find anything resembling this.
Does such an addon exist anywhere?

Thanks,
Jon
