//! Cyrus SASL authentication example (requires `--features cyrus-sasl`).
//!
//! Required:
//! - `SVN_URL=svn://host/repo`
//!
//! Optional:
//! - `SVN_USERNAME` / `SVN_PASSWORD`
//!
//! Notes:
//! - The `cyrus-sasl` feature uses a system-provided `libsasl2` at runtime.
//! - Whether SASL is used depends on what the server offers during auth.
