snapPointOrient

"This script is similar to what Max's 'Align Tool' does - except you can bind this to a nice hotkey or toolbar button. This will take all selected objects and snap them all to the position and orientation of the last selected object.

Useful for rigging where you may need to quickly align an object to another - and you don't want to keep bringing up the align window and resetting options. Also unlike the built-in Align Tool - this will allow you to snap in a hierarchy so you can snap a parent object(s) - to a childs original position.
Version 1.10 Fixes a bug where the snap might not occur right for mirrored bones or bones. "
