What it does
Mine a spawner with Silk Touch to collect it with its stored spawner data intact. If the server cannot preserve that data, the plugin leaves the spawner in place rather than silently converting it into an empty spawner.
/spawnerminer reload reloads settings (permission: spawnerminer.admin). Tab suggests reload to admins. spawnerminer.use controls use (enabled by default).
Set require-silk-touch and customize messages in config.yml. Reload with /spawnerminer reload.
