I wonder whether TEX is one of the most bugless codebases in existence. If it is, it's worth studying how Knuth arrived at it and the tools he used (literate programming). Personally, based on what I've seen, I don't like literate programming: code organized into header and source files, divided into modules (ie. classes) by files with some terse accompanying docs in text files seems more programmer-friendly. (Poor programmers can produce crap in both formalisms.)
