#![cfg_attr(feature="clippy", feature(plugin))]
#![cfg_attr(feature="clippy", plugin(clippy))]
//! Frippy is an IRC bot that runs plugins on each message
//! received.
//!
//! ## Example
//! ```no_run
//! extern crate frippy;
//!
//! frippy::run();
//! ```
//!
//! # Logging
//! Frippy uses the [log](https://docs.rs/log) crate so you can log events
//! which might be of interest.
