Drupal - Manu

It's so simple to make a menu in Drupal, just like this below:

<?php

function mac_menu(){

    $item = array();

    $item['mac/main'] = array(

        'title' => 'Mac Menu',

        'page callback' => 'main',

        'access callback' => TRUE,

    );

    return $item;

}

function main(){

    return t('Hello. This is mac main menu');

}
