What does the command 'catkin_init_workspace' do?
In reading different accounts of how to create a ROS workspace (in Hydro), I encountered a discrepancy. In the ROS tutorial sequence, a command 'catkin_init_workspace' is executed before going on to the 'build' process. In other accounts of the process, this step is not mentioned. I have not been able to find detailed documentation on this command. What exactly does it do?
