What is cpx and how does it compare to cp?

cpx is a Rust rewrite of cp, up to 5x faster with progress bars, resumes, and excludes. Install via Cargo; use like `cpx -r src dst`.

Is cpx safe for production file copies?

Yes — checksum-verified resumes, graceful interrupts. Benchmarks prove speed without corruption.

Not fully (no remotes/deltas), but killer for local transfers. Pairs great.
