## Installation

exa is written in [Rust](http://www.rust-lang.org).
Once you have it set up, a simple `make install` will compile exa and install it into `/usr/local/bin`.

exa depends on [libgit2](https://github.com/alexcrichton/git2-rs) for certain features.
If you’re unable to compile libgit2, you can opt out of Git support by running `cargo build --release --no-default-features`.
