motd should not be displayed when input is piped from another command

[nagarajasr]

i am trying to pipe a JSON string through generate-schema cli, like this:
echo '{a: "b"}' | generate-schema
the output includes the 'motd' welcome and usage message which makes it inconvenient to pipe the output to another command. i would like to do this:
echo '{a: "b"}' | generate-schema | do_something_useful_with_schema

could you please add a cli option (say, '-q' for quiet) so that generate-schema can be used seamlessly in a pipeline?

thanks
