Modernized, complete, self-contained TeX/LaTeX engine powered by XeTeX and TeXLive, written in Rust with a focus on reproducible builds and not requiring a separate, multi-gigabyte TeX Live installation — it fetches only the packages a given document actually needs, on demand, from a versioned bundle. Used by pandoc as one of its selectable PDF-producing backend engines. Aimed at users who find installing and maintaining a full TeX distribution more friction than the documents warrant.
