In daily work, when we need to know how to use a command tool(for example: kubectl), we simply execute kubectl -h or just kubectl, then the help information will be shown on the screen. However, kubectl-neat cannot be executed like that which is a little confusing if someone uses the tool directly without reading README.md carefully.

Hi @w0nwig thanks for taking the time to open this issue. kubectl-neat should print help info when the -h or --help flags are used. did that not work for you?

I mean when i simply execute kubectl-neat (without -h or --help), there's no output cause the program is waiting for stdin which is a little weird if i don't know The Default Value Of InputFile Is '-'. When i use other tools like kubectl and type kubectl on the console, my purpose is to see the help info of this tool.

The output will be like below when i type kubectl:

MacBook-Pro-WRJ:~ wrj$ kubectl
kubectl controls the Kubernetes cluster manager.
