Used this in a plugin:

$upgrader = new Plugin_Upgrader();
$options = array( 'package' => $url,
		'destination'		=> WP_PLUGIN_DIR .'/' . $folder,
		'clear_destination' => true,
		'clear_working'		=> false,
		'is_multi'			=> false,
		'hook_extra'		=> array()


$url is the url on plugin download page, $folder is the actual plugin
folder name.
