Allowing only certain arguments in launchfile
Is it possible to make roslaunch throw an exception (or set a flag, or just anything except being completely silent) when an unexpected argument is given on the command line? Expected arguments could mean the ones I declared with <arg name="expected_arg_example" />
or they could be in a list or something like that.
I find it problematic if a user doesn't get notified in any way if he e.g. mistypes or runs into version confusions or something like that.
Best regards,
Johannes
