    localization   Localization of the downloaded file, defaults to '~/Downloads'.

    extra          Currently it only accepts two options, and it can't be mixed:
        w              Downloads the video with the worst audio available
        nv             No video, downloads only audio
        na             No audio, downloads only video
        mp4            Download video in MP4 format
Current Aliases:
    alias dv2="dv 240"
    alias dv3="dv 360"
    ...
    alias dv10="dv 1080"

Note:
You cannot change the order of the arguments, because I'm lazy, but I accept PRs!
