The flake in [`mcpp-community/nix-mcpp`](https://github.com/mcpp-community/nix-mcpp)
packages the same prebuilt release binary for Linux x86_64 / aarch64 and macOS
on Apple silicon, and follows each stable release. Its overlay adds
`pkgs.mcpp-bin`: nixpkgs' `mcpp` is an unrelated C preprocessor. Per-user data
still lives in `~/.mcpp/`.

[`mcpp-community/nix-mcpp`](https://github.com/mcpp-community/nix-mcpp) 中的 flake 打包的是同一份预编译 release 二进制，支持 Linux x86_64 / aarch64 与 Apple 芯片上的 macOS，并跟随每个稳定版更新。它的 overlay 提供 `pkgs.mcpp-bin`，因为 nixpkgs 中的 `mcpp` 是一个无关的 C 预处理器。每个用户的数据仍在各自的 `~/.mcpp/` 中。
