+Utility to for advanced configuration of the following Razer mice: Copperhead
+Lachesis (Classic), DeathAdder (Classic, 3500 DPI, Black Edition, 2013), Taipan
+Naga (Classic, 2012, 2014, Hex), Krait, Boomslang CE. The tool architecture is

+commandline tool; and "qrazercfg", a QT4 based graphical device configuration
+tool.
