/**
|

* Provides AJAX-like page updating via AHAH (Asynchronous HTML and HTTP).
|
||||
*
|
||||
* AHAH is a method of making a request via Javascript while viewing an HTML
|
||||
* page. The request returns a small chunk of HTML, which is then directly
|
||||
* injected into the page.
|
||||
*
|
||||
* Drupal uses this file to enhance form elements with #ahah[path] and
|
||||
* #ahah[wrapper] properties. If set, this file will automatically be included
|
||||
* to provide AHAH capabilities.
