   "@brief A datablock that specifies an Animation Clip effect.\n\n"

   "An Animation Clip forces a target ShapeBase-derived object, such as Player or AIPlayer, to perform a particular "
   "animation sequence. Animation Clip does not supply any new animation data, but simply selects, by name, a "
   "sequence that is already defined in the target. Animation Clip can also target afxModel effects within the same "
   "choreographer."
   "\n\n"

   "The target of an Animation Clip is the constraint source object specified by the posConstraint field of the enclosing "
   "effect wrapper. The target must be a ShapeBase-derived object, or an afxModel and it must contain an animation "
   "sequence with the same name as the clipName field."
   "\n\n"

   "Animation Clip controls the rate of animation playback and can even play a sequence in reverse. When an Animation "
   "Clip selects a blended animation sequence, it is mixed with the current animation instead of replacing it. Animation "
   "Clips can be used to activate multiple, overlapping blend sequences."
   "\n\n"

   "Normally when an Animation Clip is applied to a user-controlled Player, any interactive user actions will override the "
   "animation selected by the clip, but Animation Clips can be configured to temporarily block out some user actions for "
   "the duration of the clip."
