Animating Armatures with ActionScript

For information about animating armatures with ActionScript, see the fl.ik classes in the ActionScript 3.0 Language and Components Reference.

I’ve looked through the docs, but I can’t find the way to animate an armature. I can only find read-only values. Does anyone have a better resource?

I’m using IKManager.trackAllArmatures() to move the armiture, then record all the moves in an XML file, so that I can have complex repeating animations, and I can reuse the same animation with different skins/graphics. But I can’t get that extra step…
