bat-cli 0.18.0

//! `init` and `reload`: set up a bat project, and refresh its metadata.
//!
//! bat-cli produces Miro diagrams, so a project is just `Bat.toml`, a
//! `BatMetadata.json` cache and a `figures/` directory, all at the root of the
//! audited repository. It creates no branches and no commits: what you do with
//! version control is yours to decide.
