//! Generates `python/sassy/__init__.pyi` using pyo3-introspection.
//!
//! First build the extension. On macOS, `-undefined dynamic_lookup` is required to
//! defer Python symbol resolution to load time (Linux does not need this):
//!
//!   # macOS
//!   RUSTFLAGS="-C link-arg=-undefined -C link-arg=dynamic_lookup" cargo build --features python
//!   # Linux
//!   cargo build --features python
//!
//! Then run from the repo root, passing the path to the compiled extension:
//!   cargo run --features python-stubs --bin gen_stubs -- target/debug/libsassy.dylib   # macOS
//!   cargo run --features python-stubs --bin gen_stubs -- target/debug/libsassy.so      # Linux
