//! Host-side cross-check tool for the kernel QR encoder.
//!
//! Usage: `qrcheck TEXT [VERSION] [MASK]`
//! - with VERSION+MASK: force both and dump the matrix (compared against
//! segno by `tools/qrcheck.py`);
//! - with neither: auto-pick version and best mask, print `v<ver> m<mask>`.
//!
//! Output: first line `v<N> m<N|999>`, then one line per matrix row of
//! `#` (dark) / `.` (light).
#![allow(static_mut_refs)]
#[path = "../../../rsnix/src/qr.rs"]
