Latest change 2f952519db76ba7dd8b099a09ebda909d137ea5e - feat: scaffold pure-Rust zero-dep AkurAI VPN workspace (v0.0.1) by Ólafur Búi Ólafsson

//! `akurai-admin` — the AkurAI VPN admin CLI.
//!
//! Drives the control plane: pre-auth keys, route approval, public ingress,
//! device management, and ACL edits. This is a 0.0.1 skeleton: every
//! subcommand parses its surface and prints usage, then reports that the action
//! is not yet implemented. Argument parsing is hand-rolled to keep the
//! zero-dependency promise.
