 This is a [Cargo](https://doc.rust-lang.org/cargo/) helper command which automatically creates binary [Debian packages](https://www.debian.org/doc/debian-policy/ch-binary.html) (`.deb`) from Cargo projects.

-> [!NOTE]
-> cargo-deb uses the [xz2](https://lib.rs/crates/xz2) crate that bundles an old safe version of liblzma 5.2 by the original maintainer, and a simple Cargo-based build script.
-> It is **unaffected** by the CVE-2024-3094.

 ## Installation
 
 ```sh
 rustup update   # Debian's Rust is too outdated, use rustup.rs
 cargo install cargo-deb
 ```
 
-Requires Rust 1.63+, and optionally `dpkg`, `dpkg-dev` and `liblzma-dev`. Compatible with Ubuntu. If the LZMA dependency causes you headaches, try `cargo install cargo-deb --no-default-features`.
