16//! Command-line interface and tools for [NautilusTrader](https://nautilustrader.io).
17//!
18//! The `nautilus-cli` crate provides a command-line interface for managing and
19//! operating NautilusTrader installations. It includes tools for database management,
20//! system configuration, and operational utilities:
21//!
22//! - Database initialization and management commands.
23//! - PostgreSQL schema setup and maintenance.
24//! - Configuration validation and setup utilities.
25//! - System administration and operational tools.
26//!
27//! # NautilusTrader
28//!
29//! [NautilusTrader](https://nautilustrader.io) is an open-source, production-grade, Rust-native
30//! engine for multi-asset, multi-venue trading systems.
31//!
32//! The system spans research, deterministic simulation, and live execution within a single
33//! event-driven architecture, providing research-to-live semantic parity.
34//!
35//! # Feature Flags
36//!
37//! This crate provides feature flags to control source code inclusion during compilation,
38//! depending on the intended use case:
39//!
40//! - `defi`: Enables blockchain/DeFi commands including block sync, DEX pool sync, and pool
41//!   analysis.
