Example default bukkit permissions.yml

permissions.yml

server.basics:
  default: true
  children:
    arena.leave: true
    arena.join.arena: true
    arena.join.skirmish: true
    arena.join.battleground: true
    arena.join.colosseum: true
    arena.join.tourney: true
    arena.join.freeforall: true
    arena.join.deathmatch: true
    arena.join.spleef: true
    arena.join.paintball: true
    arena.class.use.gladiator: true
    arena.class.use.archer: true
    arena.class.use.monk: true
    

is this how you actually put permissions?
