fmt architecture explained
A modern formatting library for C++. This page explains the architecture RepoLens read from fmtlib/fmt at 0fc3163. It is a static, deterministic scan: modules, files, and the document set. No API key is used.

How the code is grouped
fmt is scanned as C++ under its public license (MIT). RepoLens groups files into modules from the repository layout, then writes the same document set it writes for a local project.
