Deleting the entire cache probably would have worked fine if
DebTorrent was not running. Just remember to do an apt-get update
after you restart it so it can find the right torrents again.

I don't think anything needs to be kept if you're removing all the
downloaded packages in the cache. For more advanced ideas, see this
