just is a command runner for saving and executing project-specific commands. Recipes are stored in a justfile with syntax inspired by make. Unlike make, just is not a build system. Building requires rust-opt (Rust 1.89 or newer). Cargo uses the supplied vendor archive and Cargo.lock without downloading dependencies. Rust is not required at runtime. Run just --list to list recipes and just RECIPE to run one. Recipes use sh by default; recipes using other interpreters need those installed. Only run justfiles you trust, since recipes execute arbitrary commands. The package includes a man page, Bash/Zsh/Fish completions, and examples under /usr/doc/just-*/.
