PuppetMaster was sold to E Frontier and they incorporated it into Poser 7's actual code. By doing so I'm certain that there had to be some coding changes if they added it directly to the software itself and it's doubtful that Kamalich(SP) who wrote the original Python had anything to do with the merging of the two. I could be wrong. The original was written in Python, Universal Poses I'm pretty sure were written in whatever code they use to code Poser with.
