+//! A relatively simple bot for demonstrating some of Azalea's capabilities.
+//!
+//! ## Usage
+//!
+//! - Modify the consts below if necessary.
+//! - Run `cargo r --example testbot -- [arguments]`. (see below)
+//! - Commands are prefixed with `!` in chat. You can send them either in public
+//!   chat or as a /msg.
+//! - Some commands to try are `!goto`, `!killaura true`, `!down`. Check the
+//!   `commands` directory to see all of them.
+//!
+//! ### Arguments
+//!
+//! - `--owner` or `-O`: The username of the player who owns the bot. The bot
+//!   will ignore commands from other players.
+//! - `--account` or `-A`: The username or email of the bot.
+//! - `--server` or `-S`: The address of the server to join.
+//! - `--pathfinder-debug-particles` or `-P`: Whether the bot should run
+//!   /particle a ton of times to show where it's pathfinding to. You should
+//!   only have this on if the bot has operator permissions, otherwise it'll
+//!   just spam the server console unnecessarily.
