1//! The Composer registry: `g1t.sh/-/composer/<workspace>/`, one per
2//! workspace, built from its repositories (composer.rs says how).
3//!
4//! ```sh
5//! composer config repositories.acme composer https://g1t.sh/-/composer/acme/
6//! composer config --global --auth http-basic.g1t.sh <you> <g1t token>
7//! composer require acme/lib
8//! ```
9//!
10//! Nothing is uploaded. A repository's versions are read again when it is
11//! pushed to (`git.push`), restored, renamed or moved, and once for every
12//! repository by the backfill; a request only reads what that left. A zip
13//! of a commit is made the first time it is asked for, and kept by its
14//! digest like every file here.
