//! The five output parsers, plus the unknown-format case.
//!
//! Wired in via `#[cfg(test)] mod tests;` in the parent module. These files were
//! orphaned once - present on disk but reachable by no `mod` declaration, so
//! cargo never compiled them and appending invalid Rust did not fail the build.
//! If you add a file here, declare it in this directory's `mod.rs`.
