Many of you are probably familiar with drupal_execute(). However, those familiar with it from Drupal 5.x days will have to watch a new feature in Drupal 6.x.
Here's an example of an item in a hook_menu() implementation in the Taxonomy module for Drupal 6.x:
<?php
$items['admin/content/taxonomy/add/vocabulary'] = array(
'title' => 'Add vocabulary',
'page callback' => 'drupal_get_form',
'page arguments' => array('taxonomy_form_vocabulary'),
