This is the next generation Razer device configuration tool bringing the Razer gaming experience to the free open source world. This utility is a replacement for the old deathaddercfg tool. The tool architecture is based on "razerd", which is a background daemon doing all of the lowlevel privileged hardware accesses. The user interface tools are "razercfg", a commandline tool; and "qrazercfg", a QT4 based graphical device configuration tool.
