[ros-users] cturtle action_server debug statements

On the subject of logging, I noticed today that my ~/.ros/log directory 
had grown quite large, and rxgraph was producing particularly verbose 
logs. DEBUG logging seems to be enabled at line 68 of
cturtle/ros/tools/rxgraph/src/rxgraph/__init__.py. Is this level of 
logging intentional?
