<?php
function hook_node_type($op, $info) {

  switch ($op) {
    case 'delete':
      variable_del('comment_' . $info->type);
      break;
    case 'update':
      if (!empty($info->old_type) && $info->old_type != $info->type) {
        $setting = variable_get('comment_' . $info->old_type, COMMENT_NODE_READ_WRITE);
        variable_del('comment_' . $info->old_type);
        variable_set('comment_' . $info->type, $setting);
      }
