## Overview

Pack is an interactive Arch Linux package manager. The user launches its terminal UI, selects a package operation or list, searches and selects packages, optionally reviews details, then confirms actions that run through pacman or yay. Package discovery also supports installed, AUR, orphaned, and recent lists; available packages are cached. The sampled code shows the UI and package-manager ownership, but not all detail-loading and command branches, so uncertain wiring is omitted.

Main entry points: [`src/package.rs`](https://github.com/elrondforwin/pack-rs/blob/main/src/package.rs) (Package manager), [`src/main.rs`](https://github.com/elrondforwin/pack-rs/blob/main/src/main.rs) (UI and workflow), [`src/cache.rs`](https://github.com/elrondforwin/pack-rs/blob/main/src/cache.rs) (Package cache)
