 Use the latest (beta) version by putting `"git_function_history" = { git = 'https://github.com/mendelsshop/git_function_history' }` in your cargo.toml under `[dependencies]` section.
 Use the latest [crates.io](https://crates.io/crates/git_function_history) (also beta) by putting `git_function_history = "0.5.4"` in your cargo.toml under `[dependencies]` section.
