//! Read-only git repository explorer library.
//!
//! This library provides a more Rustic interface for libgit2, built
//! on the `git2` bindings.  If you want more low-level access to your
//! repository, consider using that library instead.
//!
//! supergit aims to make queries into a git repo as typed and easy as
//! possible.  Start by creating a
//! [`Repository`](struct.Repository.html), and enumerating or
//! fetching [`Branch`](struct.Branch.html)es that you are interested
//! in.
//!
//! Unlike `libgit2`, this library can resolve reverse dependencies
//! between files, and their commit history.  Some of these functions
//! are very computationally intensive, and will be marked with their
//! runtime cost.
