This plugin defines one command: /suicide. It kills the person who types the command.
This plugin may eventually define other unique commands that allow players to kill themselves in creative ways (slow death by poison?). It will never add commands that affect other players or the environment.
Since this plugin is so small and simple, I have simply bundled the source code inside the plugin's jar, CBSuicide.jar. Eventually I will put the source code in a repository so people can find it and clone it more easily.
By default, everyone should have access to the /suicide command without any special configuration. If you would like to restrict access to the command, there is one permission: cbsuicide.suicide.
Please don't kill yourself in real life. If you feel lost, please call the free and confidential hotline 1-800-273-8255 or go to http://www.afsp.org/i-am/struggling. Let's reach the end game together. :)
