/** \file plArmatureMod.h
	A modifier which manages multi-channel animation and has a physical body.
	Designed for avatars; also good for vehicles, creatures, etc.
*/

// PLARMATUREMOD
//
// An armature is an object with both a physical presence (physics behavior) and articulated animated parts.
// (The parts are not themselves physical)
// An avatar is a type of armature, as is a critter, and anything else that moves around.
//
// This modifier combines multi-channel animation with blending (inherited from plAGMasterMod)
// with convenience functions for moving a physical body around and some specialized animation support
