Quarkdown — Open-source Markdown supertool for books, slides, PDFs, docs, and presentations

Quarkdown is an open-source Markdown-based typesetting system designed for creating books, PDFs, slides, documentation, knowledge bases, and presentations from a single source.

Unlike traditional Markdown tools, Quarkdown adds scripting, functions, variables, layouts, and advanced document features while keeping a relatively clean Markdown syntax.
