17//! Semantics of the shell language.
18//!
19//! This crate defines the standard semantics for the shell language. The core
20//! of the semantics is command execution and word expansion.
21//! A command can be executed by calling
22//! [`Command::execute`](command::Command::execute).
23//! A word can be expanded by using functions and traits defined in
24//! [`expansion`].
25//!
26//! The [`read_eval_loop`] reads, parses, and executes commands from an input.
27//! It is a utility for running a shell script.
