## Overview

This is a small Spigot example plugin. On enable, the plugin registers its join-event listener and installs the `/echo` command executor; join events and echo commands broadcast messages through Bukkit. The README documents the player-facing command behavior. The plugin descriptor is present in the tree, but its contents were not sampled, so its specific declarations are not shown.
