[Boost-users] Is boost a library or a framework?

Hi, My head has been spinning lately on trying to nail down the difference between a library and a framework. One of my co-workers calls Boost a framework because it is a collaboration of components, and the fact that boost is so large makes it a framework. However, boost boasts itself as a library and I'm just wondering why it is such. One definition I read for a framework is that it has no requirement to be minimal, and boost is a fairly un-minimal library.
