Yeah, I don't have one either. Similarly, I couldn't find anything
applicable to the PG implementation except references to the paper.
Wikipedia has the algorithm itself
(http://en.wikipedia.org/wiki/Kruskal's_algorithm), but I was more
interested in the actual applicability to PG and any issues they ran
into.
