Armature Rigging Modules is a Blender add-on for modular rigging of almost any armature. It sets up rigging for arms, legs, feet, hands, spines and heads with scripted mechanics, and works on existing armatures.

Armature Deform Controls is a Blender add-on from Jim Kroovy for working with existing skeletal assets from other applications. It sets up bones that indirectly manipulate the source armature's original bones with Blender-friendly orientations.
