{Thirty years of literate programming and more?} {Bart Childs} {Don Knuth created Literate Programming about thirty years ago. It could be called a methodology, discipline, paradigm, \dots\ Bentley's ``Programming Pearls'' article about Knuth's book, \textsl{\TeX: The Program}, caused a huge stir in the computing professions. Soon there was announcement of a Literate Programming section for the \textsl{\acro{CACM}}\null. There then appeared a number of ``Literate Programming systems''. The use of the term Literate Programming is often applied to systems that have few of the characteristics of Knuth's \texttt{WEB}. There are at least two systems that are still in use that are quite faithful to the philosophy that Knuth elucidated in his original Pascal based \texttt{WEB} system: \texttt{CWEB} and \texttt{FWEB}. These support at least three languages each. Most other systems are relatively independent of language. I will propose a definition for Literate Programming that will be used in my comments about some of these systems. I will also discuss some items from my archives (or memory) about this and related subjects. Some come from teaching the freshman year of computer science using literate programming. I believe that this style of program development is a great contribution to the goal of creating excellent and maintainable programs. I have often wondered how many of the errors that Knuth has rewarded us for would have even been found if the program had been in the style of Unix ``pretty printing''. In spite of this, it is referenced too little. I will offer my opinions as to why this tragedy persists, what I/we should have done\Dash based on my humble view from my faulty crystal ball. }
