To give a short example of this feature, create the following module:

<?php

  $modifiers[] = "customer"; // This module modifies the customer node.

  class mod_myextensions extends atkModule
  {
     function customer_modifier(&$node)
     {
        $node->add(new atkAttribute("taxcode"));
     }
  }

?>

Put this code in module.inc in a directory named myextensions (or 
whatever you name your module). Then, in config.inc.php, put this line:

module("myextensions", "../path/to/your/modules/myextensions/");

No, don't add them to config.modules.inc. Put them in config.inc.php, so 
you only have to migrate your config.inc.php file when a new Achievo is 
released.

Don't give away all the fun yet :)
