Example code for doing activate/deactivate/uninstall hooks in a WordPress plugin

activate-deactivate-uninstall-example.php

<?php

// Change /*CUSTOMIZE_THIS*/ to a unique name (two places). Go ahead, make it long.
// Like, your initials, and your full plugin name.
// e.g. MTJ_Some_Awesome_Plugin_Controller

/*CUSTOMIZE_THIS*/_Controller::init();

class /*CUSTOMIZE_THIS*/_Controller {
	function init() {
		register_activation_hook(   __FILE__, array( __CLASS__, 'activate'   ) );
		register_deactivation_hook( __FILE__, array( __CLASS__, 'deactivate' ) );
	}
	function activate() {
		// Add options, initiate cron jobs here
		register_uninstall_hook( __FILE__, array( __CLASS__, 'uninstall' ) );
	}
	function deactivate() {
		// Remove cron jobs here
	}
	function uninstall() {
		// Delete options here
	}
}

When is the uninstall hook fired? I seem not to be able to fire it.
