The package provides facilities for the conversion of markdown markup to plain TeX. These are provided both in form of a Lua module and in form of plain TeX, LaTeX, and ConTeXt macro packages that enable the direct inclusion of markdown documents inside TeX documents. Architecturally, the package consists of the Lunamark Lua module by John MacFarlane, which was slimmed down and rewritten for the needs of the package. Lunamark provides speedy markdown parsing for the rest of the package. On top of Lunamark sits code for the plain TeX, LaTeX, and ConTeXt formats by Vít Novotný.
