mdBook architecture explained

Create a book from Markdown files. Like GitBook, implemented in Rust. This page explains the architecture RepoLens read from rust-lang/mdBook at 43b8aee. It is a static, deterministic scan: modules, files, and the document set. No API key is used.

How the code is grouped

mdBook is scanned as Rust under its public license (MPL-2.0). RepoLens groups files into modules from the repository layout, then writes the same document set it writes for a local project.
