Adjust display brightness from the Terminal

Does anyone know of a fully-functional way of adjusting my MacBook Pro's display brightness using the Terminal? The binary I was using in Snow Leopard no longer works.


No AppleScripts or UI Scripting, please, but rather a genuine command-line tool.


Thanks 🙂
