Controling where it's held

I want to write a script that will change the position of where an item is attached (i.e. where it's being held as opposed to the place it's attached to).

For example I want my av to have a staff (read wand), that is held like a quterstaff (in the center), when carred but when being used it's held the end.

So any pointers as to how I could write this would be greatfully recived.

I believe this would have to use custom animations to adjust the part of the AV that the staff is actually attached to, to move it in the orientation you want.

The way I've seen this done is to have two linked prims, one for each position, and the script just controls which one is visible at any given time. This allows users who are experienced at editing such things to position them independently, something that they can't do with an animation.
