How does VRF relate to VPN?

In the world of extranets (hub and spoke), what is a VRF in relation to VPN? I am trying to understand multiple VPNs and MPLS networks.
A VRF (VPN Routing and Forwarding) is a component of a VPN. A VPN is used to connect offices and users together so that they can exchange data. In order to figure out how to route traffic between sites, the VPN needs to build routing information so that packets will be correctly routed between sites.
