reinhardt-admin-cli 0.1.3

#![warn(missing_docs)]

//! Reinhardt Admin CLI
//!
//! Global command-line tool for Reinhardt project management.
//! This is the equivalent of Django's `django-admin` command.
//!
//! ## Installation
//!
//! While Reinhardt is on a pre-release (`-rc.*` / `-alpha.*`),
//! `cargo install` requires an explicit `--version` because pre-releases
//! are not selected by default. Once `0.1.0` stable ships, `--version`
//! becomes optional. The literal below is auto-bumped by release-plz on
//! each release.
//!
//! <!-- reinhardt-version-sync -->
//! ```bash
//! cargo install reinhardt-admin-cli --version "0.1.3"
//! ```
//!
//! ## Usage
//!
//! ```bash
//! reinhardt-admin startproject myproject --with-rest
//! reinhardt-admin startproject myproject --with-pages
//! reinhardt-admin startapp myapp --with-rest
//! reinhardt-formatter fmt src/
//! reinhardt-admin --help
//! ```
