When you download a "collection" (2-MAN..., LINUX-MAN..., FULL-MAN...) you can choose which torrents you want to dl like in a regular torrent. When you are done downloading them you remove that torrent and instead add all the "small" .torrents (1-A.torrent) that come with the collection. That way the library can be expanded daily.
