Uploading objects into Alice library...

I'm new to Alice and actually not familliar with it.
What I'm asking about is how to upload your objects into Alice library?
As I'm going to create them using Auto Desk Maya program. Knowing that you have to apply methods to different parts of your object, such as Arms, legs, and almost anything. How to integrate them as a whole charachter and yet have the ability to animate and move each part alone?
Thank you
