[Discuss-gnuradio] Mechanism to build in command line help into the flowgraph?

[Monahan-Mitchell, Tim]

I have testers that might not see the graphical version of the flowgraph they 
are testing. To them, they run the flowgraph on the command line, passing in 
various parameter values using the Short IDs set up in the original flowgraph 
and built by GRC for the target.

Is there a way, for example, to pass in "-h" or similar and the flowgraph spits 
out help text documentation and exits?

I would want this to be created without manually changing the files that GRC 
produces when it builds the flowgraph.

Thanks in advance,
Tim Monahan-Mitchell
