why system lack moveit_setup_assistant package

edit

Hi, when i use the command:

roslaunch moveit_setup_assistant setup_assistant.launch

the warning information as followed:

[setup_assistant.launch] is neither a launch file in package [moveit_setup_assistant] nor is [moveit_setup_assistant] a launch file name
The traceback for the exception was written to the log file

then i use echo $ROS_PACKAGE_PATH, output the following infomation /home/fhg/catkin_ws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks

the moveit has been installed in my unbuntu 14.04 64bit system

rospack find move +//fast double click tab key,then out put:

moveit_core                     moveit_planners_ompl            moveit_ros_manipulation         moveit_ros_planning             moveit_ros_visualization
moveit_fake_controller_manager  moveit_ros_benchmarks           moveit_ros_move_group           moveit_ros_planning_interface   moveit_ros_warehouse
moveit_msgs                     moveit_ros_benchmarks_gui       moveit_ros_perception           moveit_ros_robot_interaction    moveit_visual_tools

then i use rospack find command to check and find there are no moveit_setup_assistant package in my system.

So,i decided to install the package use the following command:

fhg@fhg-ThinkPad-T500:~$ sudo apt-get install ros-indigo-moveit-setup-assistant
