I would drop the second line from the manual. It's basically the same error 
repeated at the backend level.

Should the manual point directly to the linux binary? There are binaries for 
Windows and Mac OS X too. Maybe point to the builds directory, and let people 
pick the OS themselves?

I think it would be a good idea to add that you can obtain the list of supported 
models (and a short help) by executing the tool without any arguments.
