You've pointed out something useful: a quick attempt (by me, in this
case) to describe the algorithm isn't worth much, less so if it's
already well-documented. Hopefully the original poster can consult a
more authoritative reference on the topic. Fortunately, that was also
one of my points :-)

The implementation itself seems to do the job the OP asked. I hope
it's useful in some form.
