     """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".

+
+    YoutubeDL 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, YoutubeDL objects have a method that allows
+    InfoExtractors to be registered in a given order. When it is passed
+    a URL, the YoutubeDL object 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
+    YoutubeDL process the extracted information, possibly using a File
+    Downloader to download the video.
+
+    YoutubeDL objects 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 YoutubeDL 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.
+    videopassword:     Password for acces a video.
+    usenetrc:          Use netrc for authentication instead.
+    verbose:           Print additional info to stdout.
+    quiet:             Do not print messages to stdout.
+    forceurl:          Force printing final URL.
+    forcetitle:        Force printing title.
+    forceid:           Force printing ID.
+    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.
+    nooverwrites:      Prevent overwriting files.
+    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.
+    writedescription:  Write the video description to a .description file
+    writeinfojson:     Write the video description to a .info.json file
+    writethumbnail:    Write the thumbnail image to a file
