Perhaps the most insane example of literate programming is Axiom [https://en.wikipedia.org/wiki/Axiom_(computer_algebra_system) https://en.wikipedia.org/wiki/Axiom_(computer_algebra_system...], which is several books worth. It wasn't originally written in literate style, but it was a very large codebase which almost nobody understood. Tim Daly put an enormous amount of effort into making it literate, so that anybody can be introduced to it.
