Help - Glossary - L - Literate Programming
This is a term and a concept of Donald Knuth. The idea is that one could and should try to write one's program-code as if it is literature, rather like a mathematics text, which tends to consist of non-formal text in some natural language like English and formal text in some fragment of mathematics.
The same approach is by Knuth recommended for producing documented readable code. It seems to me this may not be the way to write code in C, but it might work in an environment like Squeak.
