dust/src/lib.rs

//! The Dust library is used to implement the Dust language, `src/main.rs` implements the command
//! line binary.
//!
//! Using this library is simple and straightforward, see the [inferface] module for instructions on
//! interpreting Dust code. Most of the language's features are implemented in the [tools] module.
