#![no_std]

//! Embed git information in your code at compile-time.
//!
//! ```
//! use git_version::git_version;
//! const GIT_VERSION : &str = git_version!();
//! ```
//!
//! The version number will have a `-modified` suffix if your git worktree had
//! untracked or changed files.
//!
//! These macros do not depend on libgit, but simply uses the `git` binary directly.
//! So you must have `git` installed somewhere in your `PATH`.

/// ```no_compile
/// const VERSION : &str = git_describe!("--always", "--dirty");

/// ```no_compile
