This is a new file, but (obviously) copied from EnableGPUHandler.cpp. Don't be
fooled by the clever script.

Maybe check the return from sscanf?

if (sscanf(commands[1].c_str(), "%d", &mode) != 1) {
   return SendError(connection, "Unable to parse request");
}

 
-    bool success = request->enableGPU(enable);
