> Enhance command line tools
> --------------------------
>
> Key: PDFBOX-2602
> URL: https://issues.apache.org/jira/browse/PDFBOX-2602
> Project: PDFBox
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 1.8.8, 2.0.0
> Reporter: Maruan Sahyoun
> Assignee: Maruan Sahyoun
> Priority: Minor
> Fix For: 3.0.0 PDFBox
>
>
> 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
> Additional input:
