//! # baracuda-cutlass-sys
//!
//! Header acquisition for NVIDIA CUTLASS as a baracuda workspace dependency.
//!
//! At build time, this crate sparse-checks-out CUTLASS headers from
//! <https://github.com/NVIDIA/cutlass> into a file-locked global cache and
//! emits Cargo metadata so downstream `build.rs` files (notably
//! [`baracuda-forge`]) and `cc` / `bindgen` invocations can locate the
//! headers without hand-rolling path discovery.
//!
//! CUTLASS is template-only C++; there is no stable C ABI to bind to.
//! Accordingly, this crate exposes no FFI types — its job is to make the
//! headers available, not to wrap them.
//!
//! See the crate `README.md` for version-selection knobs (the `cutlass-2-11`
//! feature, the `CUTLASS_DIR` and `BARACUDA_CUTLASS_COMMIT` env vars).
//!
//! [`baracuda-forge`]: https://docs.rs/baracuda-forge
