Knuth describes a *practitioner* in the introduction of his 1984 paper[fn:knuth-1984], as an essayist concerned with exposition and excellence of style. Someone who carefully selects the name for each variable and describes their meaning. They will strive for a program that is comprehensible because concepts are introduced in a manner best for human understanding.

Programming paradigm in which a computer program is given an explanation of its logic in a natural language, such as English, interspersed with snippets of macros and traditional source code, from which compilable source code can be generated.

Illustrated above we see the process of *weaving* and *tangling* the literate source file ~org~, and how each of the produced components is handled respectively. It's not difficult to imagine a situation where an update to a program would update the all of the interested parties. Source code is typically built and tested without requiring the documentation, and in the same sense someone providing support for an application should not be required to dig through the source code to locate documentation.

| doc | Human readable documentation |
