How to use Maven 3 mixins?

Question

I was trying to figure out how mixins are defined in Maven 3, but couldn't find anything other than buzz. It is propagated as one of the big new features here and here. I am currently feeling the pain of the hierarchical structure and would like to give it a spin. Does anyone have a pointer to documentation or the source defining the syntax even?

And AFAIK, mixins still aren't there.
