It's a very old posing script made by Bushi a long time ago. I still find it usefull for some poses. From the included PDF:

"PoseGenie is a PoserPython script for use with Poser ProPack and Poser 5,
The script was developed as a tool to make posing figures easier and with better
results then positioning by hand. It uses a Genetic Algorithm to quickly sift
through a very large number of possible joint rotation combinations to select a
solution for a given pose. The user selects the actors (body parts) to pose and
positions three spheres that control where the actors are to be located.
PoseGenie then sieves through the possible combinations of joint rotations that
will result in the proper positioning with the fewest number of total degrees in the
joint rotations. The script can also set limits on the range of motion in the figure’s
joints so that the Genetic Algorithm can be channeled to produce a desired pose."
