 libgit2 bindings for Rust.

+
+## Features
+
+By default, git2 includes support for working with local repositories, but does
+not include network support (e.g. cloning remote repositories). If you want to
+use features that require network support, you may need the `"https"` and/or
+`"ssh"` features. If you support user-provided repository URLs, you probably
+want to enable both.
