Literate programing is used to tangle text and code. You tangle the document and the code blocks are pulled out to create a working program. But Orgmode's Babel, iPython and Wolfram's Computational Essays are literate computing, with code being executed in the document. Howard Abrams has extended the concept to create literate devops (https://www.youtube.com/watch?v=dljNabciEGg https://www.youtube.com/watch?v=dljNabciEGg) using orgmode babel where the code in the document is used to configure software running on local or remote servers. I use Babel as part of my daily workflow. Very cool stuff.
