class Options:
    """
    Options used when invoking the script from another Python script.
    
    Simple container class used when calling get_media() from another Python
    script. The variables corresponds to the command line parameters parsed
    in main() when the script is called directly.
    
    When called from a script there are a few more things to consider:
    
    * Logging is done to 'log'. main() calls setup_log() which sets the
      logging to either stdout or stderr depending on the silent level.
      A user calling get_media() directly can either also use setup_log()
      or configure the log manually.

    * Progress information is printed to 'progress_stream' which defaults to
      sys.stderr but can be changed to any stream.
    
    * Many errors results in calls to system.exit() so catch 'SystemExit'-
      Exceptions to prevent the entire application from exiting if that happens.
