What does bamfdaemon do?

When you open a program, Unity will either pop up a new icon on the launcher(dock) and/or add an arrow to an existing icon. Each icon is not an executable; it is a .desktop file. bamfdaemon helps this by determining whether an arrow needs to be added to an existing icon, or a new icon be popped up, along with other behaviors dependent on application identity.

I think it is related to Unity Integration for websites. I hope I am right ...
