Hi, guys. What do you about redsvd?

Will eigen incorporate derived projects like this?

I did not know about this project, but it sounds really great. Now I know where to send people asking for such features!

Sure. But..., in case you didn't notice, I had a question followed
What's Eigen's attitude about incorporating or cooperating with these related projects?

I'm personally very open and it would indeed make sense to have this kind of projects inside Eigen itself.
