Anu wrote this in one of his explanation paragraphs: Listat grew out of a sed, awk and shell hack I put together
Ok--I can understand that Listat is something that grew out of something he put together, and I think "hack" means that it was sort of put together of pieces that weren't necessarily designed to work together. But what on earth is "sed, awk and shell"? That sounds SO strange, to me!
