//! Simple echo bot. Every text message sent to the bot gets echoed back.
//!
//! This runs as a bot (not your personal account), so it only receives
//! messages that people send directly to it. Safe to leave running.
//!
//! Run:
//!   cargo run --example echo_bot
//!
//! Fill in API_ID, API_HASH and BOT_TOKEN below.
//! Get API credentials from https://my.telegram.org
//! Get a bot token from @BotFather on Telegram.
