What are the symlinks for in /etc/ssl/private ? (Ubuntu server)

I want to backup my certificates and I see that there are lot of symlinks in /etc/ssl/private and I'm not sure why they are here. Does anyone have an idea?

I am running Ubuntu Server Jaunty 9.10 and LAMP.

listing, (I renamed my certs to cert*.crt for privacy):
