 # AURCache
 
 AURCache is a build server and repository for Archlinux packages sourced from the AUR (Arch User Repository). It features a Flutter frontend and Rust backend, enabling users to add packages for building and subsequently serves them as a pacman repository. Notably, AURCache automatically detects when a package is out of date and displays it within the frontend.
