//! `tests/data/` for the unit tests: a path into it, and a copy of a file
//! there for a test that edits it.
//!
//! The reference C library is a dependency of the crosscheck package alone, so
//! a unit test that needs a C-written input reads a committed one under
//! `tests/data/c/`, written by `crates/crosscheck/tests/c_test_data.rs`. In the
//! other direction `src/repack.rs` commits a file it writes through a
//! crate-private seam under `tests/data/pure/`, for that package to read with
//! the C library. `just test-data` rewrites both.

/// Set, a unit test that commits a file rewrites it instead of checking it.
