The article discusses the concept of literate programming, introduced by Donald Knuth, and how it was demonstrated through a programming example. The example was criticized by Douglas McIlroy, who provided a simpler solution using shell scripting. However, the article argues that Knuth's example was misrepresented and that his goal was to demonstrate the literate programming technique, not to provide the most efficient solution. The article also explores the differences between Knuth's and McIlroy's approaches and their implications for programming.
