Cerberos is game server watch application. The general idea is to ease the administration of dedicated servers, especialy kicking and banning players not willing to applay server rules.
Yeah Cerberos do some things on his own, but you have to teach him some stuff also, like words you want him to trigger those punishments.
Cerberos is still under development and hopefully will be...
Hope you will find him effective and helpfull while running your game servers!!!
