//!
//! ## Overview
//!
//! The Parity EVM interpreter binary is a tool in the Parity
//! Ethereum toolchain. It is an EVM implementation for Parity Ethereum that
//! is used to run a standalone version of the EVM interpreter.
//!
//! ## Usage
//!
//! The evmbin tool is not distributed with regular Parity Ethereum releases
//! so you need to build it from source and run it like so:
//!
//! ```bash
//! cargo build -p evmbin --release
//! ./target/release/parity-evm --help
//! ```
