// more control over what's shown in the admin with the other arguments. To build your | |
// own UI, set this to FALSE. | |

// the post type screen be a sub-menu. | |

// this results in many extra capabilities that you probably don't need. The following is how | |
// I set up capabilities for many post types, which only uses three basic capabilities you need | |
