//! Support for the SMT-LIBv2 language.
//!
//! This module provides support for the concrete syntax of the SMT-LIBv2 language.
//! * the [ast] submodule provides types to represent a detailed abstract syntax tree of an
//! SMT-LIBv2 source file, together with their [Parsable](crate::formally::io::parse::Parsable)
//! and [Print](crate::formally::io::print::Print) instances.
//! * the [interpreter] submodule provides the [Interpreter](interpreter::Interpreter) type which is
//! in charge of actually executing SMT-LIBv2 commands.
