 ## DESCRIPTION
 **youtube-dl** is a small command-line program to download videos from
 YouTube.com and a few more sites. It requires the Python interpreter, version
-2.x (x being at least 5), and it is not platform specific. It should work in
+2.x (x being at least 6), and it is not platform specific. It should work in
 your Unix box, in Windows or in Mac OS X. It is released to the public domain,
 which means you can modify it, redistribute it or use it however you like.

+	"""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.
+	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
+	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

+
+	Information extractors are the classes that, given a URL, extract
+	information from the video (or videos) the URL refers to. This
+	information includes the real video URL, the video title and simplified
+	title, author and others. The information is stored in a dictionary
+	which is then passed to the FileDownloader. The FileDownloader
+	processes this information possibly downloading the video to the file
+	system, among other possible outcomes. The dictionaries must include
+	the following fields:
+
+	id:		Video identifier.
+	url:		Final video URL.
+	uploader:	Nickname of the video uploader.
+	title:		Literal title.
+	ext:		Video filename extension.
+	format:		Video format.
+	player_url:	SWF Player URL (may be None).
+
+	The following fields are optional. Their primary purpose is to allow
+	youtube-dl to serve as the backend for a video search function, such
+	as the one in youtube2mp3.  They are only used when their respective
+	forced printing functions are called:
+
+	thumbnail:	Full URL to a video thumbnail image.
+	description:	One-line video description.
+
+	Subclasses of this one should re-define the _real_initialize() and
+	_real_extract() methods and define a _VALID_URL regexp.
+	Probably, they should also be added to the list of extractors.

-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.
-	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
-	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

-
-	Information extractors are the classes that, given a URL, extract
-	information from the video (or videos) the URL refers to. This
-	information includes the real video URL, the video title and simplified
-	title, author and others. The information is stored in a dictionary
-	which is then passed to the FileDownloader. The FileDownloader
-	processes this information possibly downloading the video to the file
-	system, among other possible outcomes. The dictionaries must include
-	the following fields:
-
-	id:		Video identifier.
-	url:		Final video URL.
-	uploader:	Nickname of the video uploader.
-	title:		Literal title.
-	stitle:		Simplified title.
-	ext:		Video filename extension.
-	format:		Video format.
-	player_url:	SWF Player URL (may be None).
-
-	The following fields are optional. Their primary purpose is to allow
-	youtube-dl to serve as the backend for a video search function, such
-	as the one in youtube2mp3.  They are only used when their respective
-	forced printing functions are called:
-
-	thumbnail:	Full URL to a video thumbnail image.
-	description:	One-line video description.
-
-	Subclasses of this one should re-define the _real_initialize() and
-	_real_extract() methods and define a _VALID_URL regexp.
-	Probably, they should also be added to the list of extractors.
