class FileDownloader(object):
    """File Downloader class.

    File downloader objects are the ones responsible of downloading the
    actual video file and writing it to disk if the user has requested
    it, among some other tasks. In most cases there should be one per
    program. As, given a video URL, the downloader doesn't know how to
    extract all the needed information, task that InfoExtractors do, it
    has to pass the URL to one of them.

    For this, file downloader objects have a method that allows
    InfoExtractors to be registered in a given order. When it is passed
    a URL, the file downloader handles it to the first InfoExtractor it
    finds that reports being able to handle it. The InfoExtractor extracts
    all the information about the video or videos the URL refers to, and
    asks the FileDownloader to process the video information, possibly
    downloading the video.

    File downloaders accept a lot of parameters. In order not to saturate
    the object constructor with arguments, it receives a dictionary of
    options instead. These options are available through the params
    attribute for the InfoExtractors to use. The FileDownloader also
    registers itself as the downloader in charge for the InfoExtractors
    that are added to it, so this is a "mutual registration".

    Available options:

    username:          Username for authentication purposes.
    password:          Password for authentication purposes.
    usenetrc:          Use netrc for authentication instead.
    quiet:             Do not print messages to stdout.
    forceurl:          Force printing final URL.
    forcetitle:        Force printing title.
    forcethumbnail:    Force printing thumbnail URL.
    forcedescription:  Force printing description.
    forcefilename:     Force printing final filename.
    simulate:          Do not download the video files.
    format:            Video format code.
    format_limit:      Highest quality format to try.
    outtmpl:           Template for output names.
    restrictfilenames: Do not allow "&" and spaces in file names
    ignoreerrors:      Do not stop on download errors.
    ratelimit:         Download speed limit, in bytes/sec.
    nooverwrites:      Prevent overwriting files.
    retries:           Number of times to retry for HTTP error 5xx
    buffersize:        Size of download buffer in bytes.
    noresizebuffer:    Do not automatically resize the download buffer.
    continuedl:        Try to continue downloads if possible.
    noprogress:        Do not print the progress bar.
    playliststart:     Playlist item to start at.
    playlistend:       Playlist item to end at.
    matchtitle:        Download only matching titles.
    rejecttitle:       Reject downloads for matching titles.
    logtostderr:       Log messages to stderr instead of stdout.
    consoletitle:      Display progress in console window's titlebar.
    nopart:            Do not use temporary .part files.
    updatetime:        Use the Last-modified header to set output file timestamps.
    writedescription:  Write the video description to a .description file
    writeinfojson:     Write the video description to a .info.json file
    writesubtitles:    Write the video subtitles to a .srt file
    subtitleslang:     Language of the subtitles to download
    test:              Download only first bytes to test the downloader.
