How to programatically get current battery level with COCOA

Question

How can I get the current battery level using the cocoa framework running with Leopard?

Currently I am getting it running a NSTask with:

pmset -g ps | grep -o -e [0-9]*% | sed -e 's/%//g'

But i think this is a clumsy way of doing this.

Thanks

I believe this question has been asked here before... Here's some links:

It limited my number of links because I'm new... but you should find more links there
