## Overview

Git is a distributed revision-control system exposed as a command suite, spanning worktree changes, history and comparison, refs, and repository synchronization. Its internal repository context coordinates configuration, object access and refs; object storage and ref backends provide durable state. The README documents these product capabilities, while the sampled excerpts are sparse and do not show the main command-dispatch path. Accordingly, capability links are documented at a broad level; internal links are limited to relationships visible in the source index or excerpts.

Main entry points: [`git.c`](https://github.com/batman1batman/git/blob/master/git.c) (Git command suite), [`repository.c`](https://github.com/batman1batman/git/blob/master/repository.c) (Repository context), [`builtin/fetch.c`](https://github.com/batman1batman/git/blob/master/builtin/fetch.c) (Fetch and pull), [`builtin/push.c`](https://github.com/batman1batman/git/blob/master/builtin/push.c) (Push and send)
