-  module Helpers
-    # Provides a set of helpers for creating JavaScript macros that rely on and often bundle methods from JavaScriptHelper into
-    # larger units. These macros also rely on counterparts in the controller that provide them with their backing. The in-place
-    # editing relies on ActionController::Base.in_place_edit_for and the autocompletion relies on 
-    # ActionController::Base.auto_complete_for.
-    module JavaScriptMacrosHelper      
-      # DEPRECATION WARNING: This method will become a separate plugin when Rails 2.0 ships.
-      #
-      # Adds AJAX autocomplete functionality to the text input field with the 
-      # DOM ID specified by +field_id+.
-      #
-      # This function expects that the called action returns an HTML <ul> list,
-      # or nothing if no entries should be displayed for autocompletion.
-      #
-      # You'll probably want to turn the browser's built-in autocompletion off,
-      # so be sure to include an <tt>autocomplete="off"</tt> attribute with your text
-      # input field.
-      #
-      # The autocompleter object is assigned to a Javascript variable named <tt>field_id</tt>_auto_completer.
-      # This object is useful if you for example want to trigger the auto-complete suggestions through
-      # other means than user input (for that specific case, call the <tt>activate</tt> method on that object). 
-      # 
-      # Required +options+ are:
-      # <tt>:url</tt>::                  URL to call for autocompletion results
-      #                                  in url_for format.
-      # 
-      # Addtional +options+ are:
-      # <tt>:update</tt>::               Specifies the DOM ID of the element whose 
-      #                                  innerHTML should be updated with the autocomplete
-      #                                  entries returned by the AJAX request. 
-      #                                  Defaults to <tt>field_id</tt> + '_auto_complete'
-      # <tt>:with</tt>::                 A JavaScript expression specifying the
-      #                                  parameters for the XMLHttpRequest. This defaults
-      #                                  to 'fieldname=value'.
-      # <tt>:frequency</tt>::            Determines the time to wait after the last keystroke
-      #                                  for the AJAX request to be initiated.
-      # <tt>:indicator</tt>::            Specifies the DOM ID of an element which will be
-      #                                  displayed while autocomplete is running.
-      # <tt>:tokens</tt>::               A string or an array of strings containing
-      #                                  separator tokens for tokenized incremental 
-      #                                  autocompletion. Example: <tt>:tokens => ','</tt> would
-      #                                  allow multiple autocompletion entries, separated
-      #                                  by commas.
-      # <tt>:min_chars</tt>::            The minimum number of characters that should be
-      #                                  in the input field before an Ajax call is made
-      #                                  to the server.
-      # <tt>:on_hide</tt>::              A Javascript expression that is called when the
-      #                                  autocompletion div is hidden. The expression
-      #                                  should take two variables: element and update.
-      #                                  Element is a DOM element for the field, update
-      #                                  is a DOM element for the div from which the
-      #                                  innerHTML is replaced.
-      # <tt>:on_show</tt>::              Like on_hide, only now the expression is called
-      #                                  then the div is shown.
-      # <tt>:after_update_element</tt>:: A Javascript expression that is called when the
-      #                                  user has selected one of the proposed values. 
-      #                                  The expression should take two variables: element and value.
-      #                                  Element is a DOM element for the field, value
-      #                                  is the value selected by the user.
-      # <tt>:select</tt>::               Pick the class of the element from which the value for 
-      #                                  insertion should be extracted. If this is not specified,
-      #                                  the entire element is used.
-      # <tt>:method</tt>::               Specifies the HTTP verb to use when the autocompletion
-      #                                  request is made. Defaults to POST.
