Keyboard backlit light control from command line

I haven't found a great solution yet. Here is some information that can help:

• Apparently there is a solution for Ubuntu on MacBooks.

• Lab Tick runs on OS X but unfortunately not command-line (nor open source).

• brightness is free software to control the display brightness.

This turns off automatic backlight in low light:

defaults write com.apple.BezelServices kDim -bool false

This turns off keyboard illumination when computer is not used for 1 second:

defaults write com.apple.BezelServices kDimTime -int 1

But ideally I would just turn off the illumination under all circumstances. And I haven't found a CLI solution for that - yet.
