gnome-bluetooth is a fork of bluez-gnome focused on integration with the GNOME desktop environment (see also this blog entry for details).
gnome-bluetooth is the historical name of the first GNOME focused Bluetooth effort for Linux. As such, when the need came to name this project, we selected something that was still in the peoples minds. You can find historical versions of gnome-bluetooth in the GNOME git repository.
gnome-bluetooth does not include the bluez-gnome analyzer, or the proximity tool.
The original GNOME Bluetooth was developed by Edd Dumbill, bluez-gnome was developed by Marcel Holtmann. The current primary maintainer is now Bastien Nocera. The software is free, licensed under the GPL for the programs, and LGPL for the libraries. See individual source files for copyright information.
