  96     """YoutubeDL class.
  97
  98     YoutubeDL objects are the ones responsible of downloading the
  99     actual video file and writing it to disk if the user has requested
 100     it, among some other tasks. In most cases there should be one per
 101     program. As, given a video URL, the downloader doesn't know how to
 102     extract all the needed information, task that InfoExtractors do, it
 103     has to pass the URL to one of them.
 104
 105     For this, YoutubeDL objects have a method that allows
 106     InfoExtractors to be registered in a given order. When it is passed
 107     a URL, the YoutubeDL object handles it to the first InfoExtractor it
 108     finds that reports being able to handle it. The InfoExtractor extracts
 109     all the information about the video or videos the URL refers to, and
 110     YoutubeDL process the extracted information, possibly using a File
 111     Downloader to download the video.
 112
 113     YoutubeDL objects accept a lot of parameters. In order not to saturate
 114     the object constructor with arguments, it receives a dictionary of
 115     options instead. These options are available through the params
 116     attribute for the InfoExtractors to use. The YoutubeDL also
 117     registers itself as the downloader in charge for the InfoExtractors
 118     that are added to it, so this is a "mutual registration".
