## Project history and usage

Mmark is Miek Gieben's Go-based Markdown processor for IETF authoring. Its upstream material describes it as a powerful Markdown processor geared toward IETF documents, but also usable for books and technical documentation. The IETF authors' tools catalog lists mmark as a Markdown-to-RFCXML tool, credits Miek Gieben as author and maintainer, and classifies it as a maintained command-line/build tool.

### Project history

The tool's main milestone is support for the RFC 7991 XML vocabulary used by xml2rfc v3. Mmark takes an extended Markdown dialect with title blocks, special sections, citations, XML references, BCP14 keyword handling, captions, figures, includes, indexes, and cross references, then emits RFCXML, HTML5, or manual-page output. The generated RFCXML is meant to be passed to xml2rfc for final text, HTML, PDF, or other RFC outputs.

### How it is used

Mmark belongs to the small ecosystem of tools that let IETF authors write Internet-Drafts in lightweight text formats instead of raw XML. It sits near kramdown-rfc and metanorma-ietf, with a package-manager niche as a single CLI for authors who want local Markdown-to-RFCXML conversion in scripts, Makefiles, and continuous document builds.
