//! Translates a shell script into a command-stream module with `$fy`.
//!
//! ```sh
//! cargo run --example fy_translate -- ../fixtures/fy/sample.sh
//! ```
//!
//! The translation is rule-based: the script is first formalized as a
//! link-foundation/meta-language links network, then rewritten into JavaScript
//! by a `TranslationRuleSet`. Diagnostics for untranslated constructs go to
//! stderr, so the stdout stream is exactly the translated module.
