----------------------------------------

I'm looking to utilize an annotation based lib such as [Picocli|https://picocli.info/] (ASF licensed) to help enhance our command line tools (and the pdfbox-app) as I think that's more descriptive. Thoughts?
Otherwise I'll go with Apache Commons CLI

> The command line tools shall be enhanced to have the same behavior across all tools.
> From the discussion on the dev mailing list
> - add an -h option to print the usage
> - print the usage to System.err and use an exit code of 1 if there was an invalid command line parameter
> - print messages on exceptions to System.err
> - rethrow the exception so java can handle it if it will terminate afterwards anyway
> - use an exit code of 1if rethrowing doesn't make sense
