airs-cli 0.4.1

//! `runtime profiles create`, `update <nameOrId>` and `delete|rm <nameOrId>` (DESIGN
//! §13.12–§13.14).
//!
//! Argument checks run in planning (exit 2); `--config` files and the flag-built body are
//! read and validated before the tenant; `update` reads the profile once, last, and
//! writes the body computed from that read (§13.4).
