Suppressing the "usage: " message

[pitosalas]

I have a simple tool which prints a prompt and the user types commands. I am using click to parse the commands. When I type "help" I get this output. I don't want to see the "Usage" line because it is incorrect and unnecessary. I cant find what is triggering it.
