 /* TODO Automatically add Drupal.settings.basePath  
    In Drupal 5, you would have to add the base path to Drupal.settings yourself  
    if you needed it (it's needed for just about every AHAH/AJAX enabled module  
    if you did it right). Now in Drupal 6, it's added automatically. You can always  
    find it at Drupal.settings.basePath (actually, as soon as drupal_add_js() is  
    called at least once, so this is similar to the way we automatically add  
    drupal.js and jquery.js. */  
   
 /* TODO db_next_id() is gone, and replaced as db_last_insert_id()  
    Since db_next_id() introduce some problems, and the use of this function  
    can be replaced by database level auto increment handling, db_next_id()  
    is now gone and replaced as db_last_insert_id() with help of serial type  
    under Schema API (check out http://drupal.org/node/149176 for more details).  
    Please refer to drupal_write_record() as demonstration. */  
   
 /* TODO FormAPI image buttons are now supported.  
    FormAPI now offers the 'image_button' element type, allowing developers to  
    use icons or other custom images in place of traditional HTML submit buttons.  
   
 $form['my_image_button'] = array(  
   '#type'         => 'image_button',  
   '#title'        => t('My button'),  
   '#return_value' => 'my_data',  
   '#src'          => 'my/image/path.jpg',  
 ); */  
   
 /* TODO hook_nodeapi('submit') has been replaced by op='presave'  
    There is no longer a 'submit' op for nodeapi. Instead you may use the newly  
    created 'presave' op. Note, however, that this op is invoked at the beginning  
    of node_save(), in contrast to op='submit' which was invoked at the end of  
    node_submit(). Thus 'presave' operations will be performed on nodes that are  
    saved programatically via node_save(), while in Drupal 5.x op='submit' was  
    only applied to nodes saved via the node form. Note that the node form is now,  
    in effect, a multistep form (for example when previewing), so if you need to  
    fix up the data in the node for re-building the form, use a #submit function  
    added to the node form's $form array. */  
   
 /* TODO Change 'Submit' to 'Save' on buttons  
    It has been agreed on that the description 'Submit' for a button is not a  
    good choice since it does not indicate what actually happens. While for  
    example on node editing forms, 'Preview' and 'Delete' describe exactly what  
    will happen when the user clicks on the button, 'Submit' only gives a vague  
    idea. When labelling your buttons, make sure that it is clear what this  
    button does when the user clicks on it. */  
   
 /* TODO Node previews and adding form fields to the node form.  
    There is a subtle but important difference in the way node previews (and other  
    such operations) are carried out when adding or editing a node. With the new  
    Forms API, the node form is handled as a multi-step form. When the node form  
    is previewed, all the form values are submitted, and the form is rebuilt with  
    those form values put into $form['#node']. Thus, form elements that are added  
    to the node form will lose any user input unless they set their '#default_value'  
    elements using this embedded node object. */  
   
 /* TODO New user_mail_tokens() method may be useful.  
    user.module now provides a user_mail_tokens() function to return an array  
    of the tokens available for the email notification messages it sends when  
    accounts are created, activated, blocked, etc. Contributed modules that  
    wish to make use of the same tokens for their own needs are encouraged  
    to use this function. */  
   
 /* TODO  
    There is a new hook_watchdog in core. This means that contributed modules  
    can implement hook_watchdog to log Drupal events to custom destinations.  
    Two core modules are included, dblog.module (formerly known as watchdog.module),  
    and syslog.module. Other modules in contrib include an emaillog.module,  
    included in the logging_alerts module. See syslog or emaillog for an  
    example on how to implement hook_watchdog.  
 function example_watchdog($log = array()) {  
   if ($log['severity'] == WATCHDOG_ALERT) {  
     mysms_send($log['user']->uid,  
       $log['type'],  
       $log['message'],  
       $log['variables'],  
       $log['severity'],  
       $log['referer'],  
       $log['ip'],  
       format_date($log['timestamp']));  
   }  
 } */  
   
 /* TODO Implement the hook_theme registry. Combine all theme registry entries  
    into one hook_theme function in each corresponding module file.  
 function cck_field_privacy_theme() {  
   return array(  
   );  
 }; */  
   
   
 /* TODO  
    An argument for replacements has been added to format_plural(),  
    escaping and/or theming the values just as done with t().*/  
   
 /* TODO You may want to take advantage of new form-specific alter hooks.  
    The hook_form_alter() is complemented by hook_form_$form-id_alter().  
    Optionally, modules can implement form-specific alteration functions rather  
    than a single hook_form_alter() with many conditional switch statements.  
    This is optional, and is most useful for tidying the code of modules that  
    alter many forms to customize a site's operations.  
    The new function names are built using the following format:  
    [your-module-name]_form_[$form_id]_alter. */
