A useful plugin for Minecraft prison servers.
Stable release! It implements the following features, so far:

• Equips orange leather armor to all prisoners upon connecting to the server and upon respawn.
• It generates a banned_items.yml file which can be configured to ban certain items for prisoners.
• It prevents the modificaiton of prisoner armor (they cannot equip/un-equip the default prisoner armor).
• It prevents banned items from being used, equipped in hand, transferred to storage or even crafted by prisoners.
• To enable the prisoner features players who are considered prisoners should have the permission nvus.prisoner.
• Just in case, all non-prisoners and players who are no longer considered a prisoner should have the permission nvus.prisoner NEGATED.
