dynparam dump recursively?

edit

Hello,

I would like to dump all dynamically reconfigurable parameters under the /move_base parameter space including those for the planner (e.g. DWAPlannerROS), the global_costmap, etc. However, if I run the command:

$  rosrun dynamic_reconfigure dynparam dump /move_base move_base.yaml

I only get the parameters in the top-level /move_base name space in the file move_base.yaml. Is there a way to have dynparam dump "drill down" through the /move_base namespace and save everything?

Thanks,
patrick
