+%description
+Controller for setting the control mode of KUKA robots at runtime. Part of the
+kuka_drivers stack for ROS 2 (humble). This package builds the
+kuka_control_mode_handler pluginlib plugin (a ros2_control controller) from
+the kuka_drivers monorepo (subdirectory controllers/kuka_control_mode_handler).
