I came to love this generic generator top node.
The only issue I have is that I cannot figure how to troubleshoot it.
Is there a way to see the code generated by the command builder?
like a print ('script') or something?

If you want to see the command that's generated for a particular work item, you can ctrl + middle-mouse click on that work item in the TOPs UI. The command line string for the work item will be listed directly in the attribute panel in H19.0 and earlier, and under the Cook Info section in H19.5. That applies to all nodes, not just the generic generator.

Cool thanks @tpetrick. I knew that I must have overlook this somehow.
