make­prog – A lit­er­ate sys­tem for TeX pro­gram­ming

A lit­er­ate pro­gram­ming sys­tem strongly in­flu­enced by the ideas of Knuth's web sys­tem, but de­signed for pro­cess­ing TeX-based sources (doc­u­men­ta­tion pro­cess­ing is pro­vided in both Plain TeX and LaTeX).
In con­trast to the LaTeX project’s doc and doc­strip, but in com­mon with Knuth's sys­tem, there is a sep­a­rate pro­gram (make­prog) for pro­duc­ing code to run (equiv­a­lent to Knuth's tan­gle). How­ever, make­prog doesn't re­ar­range code in the way that tan­gle does.
