The setConstraint command sets the constraint offset for all selected nodes based on the position and rotation of the nodes at the current frame. Selected nodes may be constraints or sources of constraints.
Used often during fine tuning the setup of a skeleton to adjust the relationship between markers and bones.

//With a marker selected, execute the setConstraint command to
// update the constraint offset
