Is a-shell includes Jigdo (jigsaw downloader based on wget)? If not please, add it.

To start it after its install, use the command:
jigdo-lite

Why is this downloader if you have also many applications to download huge files?

The principal benefit of jigdo is updating the huge ISO files without downloading the whole ISO file. It does not mean that jigdo can run contents of the ISO file (OS installer, video collection or others). It is only downloader\updater.
