     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
