Lately I've been wanting a torrent client with the same model of mpd. I currently use rtorrent, but I find the configuration confusing, and having to run it in a detached screen/tmux session feels needless. And I'm not even going to mention the endless trouble I've had when trying to set rutorrent up. Unfortunately I'm quite busy with both uni and other projects, but one day... (it goes without saying that I'd use libgbt).

EDIT: I want this so I would be able to do everything I want through a CLI, but this might also be possible with rtorrent and its XMLRPC interface. I'll have to investigate this further.

EDIT2: I'd aptly name it gbtd, methinks.
