    This command extracts information from the Info dictionary of a PDF file as well
    as some other useful information like the used PDF version and encryption information.

    If the --check option is specified, the PDF file will also be checked for parse and
    validation errors. And if the process doesn't abort, HexaPDF is still able to handle the
    file by correcting the errors.
