''' List streams in the <hwp5file>.

Usage::

    hwp5proc ls [--loglevel=<loglevel>] [--logfile=<logfile>]
                [--vstreams | --ole]
                <hwp5file>
    hwp5proc ls --help

Options::

    -h --help               Show this screen
       --loglevel=<level>   Set log level.
       --logfile=<file>     Set log file.

       --vstreams           Process with virtual streams (i.e. parsed/converted
                            form of real streams)
       --ole                Treat <hwpfile> as an OLE Compound File. As a
                            result, some streams will be presented as-is. (i.e.
                            not decompressed)

Example: List without virtual streams::

    $ hwp5proc ls sample/sample-5017.hwp
