//! Opciones de configuración.
//!
//! Example:
//!
//! ```toml
//! [database]
//! db_type = "mysql"
//! db_name = "db"
//! db_user = "user"
//! db_pass = "password"
//! db_host = "localhost"
//! db_port = 3306
//! max_pool_size = 5
//! ```
//!
//! Usage:
//!
//! ```rust
//! use pagetop_seaorm::config;
//!
//! assert_eq!(config::SETTINGS.database.db_host, "localhost");
//! ```
//! See [`pagetop::include_config`] to learn how `PageTop` read configuration files and use
//! settings.
