Lore overrides have been included with binlore's source up to now, but this hasn't worked very well. (It isn't as easy to self-service for people working in nixpkgs, and its use of partial pnames for matching breaks down around some edge cases like version numbers appearing early in perl pnames, or multiple packages having identical pnames.)
