how do I use hook_block with the form tutorial example?

I have created a form and would like to add a hook_block so I can use the from as a block.

<?php
// $Id$
/**
  * @file
  * Play with the Form API.
  */
/**
  * Implementation of hook_menu().
  */
function formexample_menu() {
   $items['formexample'] = array(
      'title' => 'View the form',
      'page callback' => 'formexample_page',
      'access arguments' => array('access content'),
   );
   return $items;
}

    /**
      * Menu callback.
      * Called when user goes to http://example.com/?q=formexample
      */
    function formexample_page() {
       $output = t('This page contains our example form.');
       // Return the HTML generated from the $form data structure.
       $output .= drupal_get_form('formexample_nameform');
       return $output;
    }
    /**
      * Define a form.
      */
    function formexample_nameform() {
       $form['user_name'] = array(
          '#title' => t('Your Name'),
          '#type' => 'textfield',
          '#description' => t('Please enter your name.'),
       );
       $form['submit'] = array(
          '#type' => 'submit',
          '#value' => t('Submit')
       );
       return $form;
    }
    /**
      * Validate the form.
      */
    function formexample_nameform_validate($form, &$form_state) {
       if ($form_state['values']['user_name'] == 'King Kong') {
          // We notify the form API that this field has failed validation.
          form_set_error('user_name',
            t('King Kong is not allowed to use this form.'));
       }
    }
    /**
      * Handle post-validation form submission.
      */
    function formexample_nameform_submit($form, &$form_state) {
       $name = $form_state['values']['user_name'];
       drupal_set_message(t('Thanks for filling out the form, %name',
          array('%name' => $name)));
	  

}

/**
 * Implementation of hook_block()
 */
function formexample_block($op='list', $delta=0, $edit=array()) {
  switch ($op) {
    case 'list':
      $blocks[0]['info'] = t('Goodreads Bookshelf');
      $blocks['content'] =  ?????
      return $blocks;

  }
}

what do I need to put for $blocks['content'] = to have the form show up as a block?
