"Literate programming (LP) offers 2 classical operations:

    Tangle: Extract the source code blocks and generate real working code files for further compilation or execution, eventually outside of Emacs.

    Weave: Export the whole Org file as literate, human-readable documentation (generally in HTML or LaTeX)."
