**Summary:** `voc` is a literate‑programming tool that lets JavaScript (and other compile‑to‑JS) developers embed executable Markdown code blocks in their documentation, automatically processing them with language‑specific handlers. It’s aimed at developers who want to write self‑documenting, runnable code examples for JS‑centric or compile‑to‑JS projects (e.g., CoffeeScript, TypeScript, Makefiles).
