Human meta-rig

I am viewing a great tutorial at Blender Cookie which refers to a “Human Meta-Rig” which is found in the Add menu / Armature. But my version 2.62 doesn’t seem to include it.

Does anyone know where I can find this item and how to get it to show up in the Add menu?

Thanks for any clues.

Enable the Rigify addon from the File / User Preferences / Addons / Rigging panel

Thanks again, Richard.
