Libertarians and abortion?

OK, I've got a question, if you all are willing. I'm quite new to libertarianism, and if I'm wrong, please say something. I like to learn.

What is your position as a libertarian on abortion? Given that the fundamental belief of libertarianism is that no one should be deprived of his life, liberty, or property, doesn't that apply to the unborn child as well? Is not abortion depriving a child at a chance at life, and therefor immoral?
