//! `gflights` — command-line interface for the gflights library.
//!
//! # Usage
//!
//! **One-shot mode** — pass a subcommand directly:
//! ```text
//! gflights search --from LHR --to JFK --date 2025-08-01 [OPTIONS]
//! gflights graph  --from LHR --to JFK --date 2025-08-01 [--months 3]
//! gflights offer  --from LHR --to JFK --date 2025-08-01
//! ```
//!
//! **Interactive mode** — run `gflights` with no arguments to enter a REPL:
//! ```text
//! gflights> search --from LHR --to JFK --date 2025-08-01
//! gflights> graph  --from MXP --to SYD --date 2025-09-01 --months 2
//! gflights> dgrid  --from LHR --to JFK --dep-start 2025-08-01 --dep-end 2025-08-07 --ret-start 2025-08-10 --ret-end 2025-08-17
//! gflights> quit
//! ```
