    commands:
        get_tasks       Get the list of tasks. This is not formatted, i.e. you'll
                        have to pipe it yourself through a formatter.
        put_document    Uploads the document under <file> to your paperless
                        instance.

    return values:
        If everything went alright, $(basename "$0") returns 0. Every other return
        value indicates an error.
