What it's for...
This script is for importing RSLT(slot) files into Blender 3D 2.59. The slots can be imported over a mesh, then moved to the desired position. Slots can also be added and deleted, and it works on routing, container, effect, and IKtarget slots. Additionally, slot flags(for container slots) can also be edited.
