I see that the rmdstestclient has a -ddict argument which I believe in theory dumps out the data dictionary to a file. I'm having trouble getting this argument to work. I tried running the program with -ddict {output_file} but didn't anything getting written out. I also tried running it with -ddict True since it looks like the default argument is "False" but don't see where the data dictionary is getting outputted to. Has anyone ever gotten this to work? What's the right set of arguments that I should be passing in?
