+module InPlaceMacrosHelper
+  # Makes an HTML element specified by the DOM ID +field_id+ become an in-place
+  # editor of a property.
+  #
+  # A form is automatically created and displayed when the user clicks the element,
+  # something like this:
+  #   <form id="myElement-in-place-edit-form" target="specified url">
+  #     <input name="value" text="The content of myElement"/>
+  #     <input type="submit" value="ok"/>
+  #     <a onclick="javascript to cancel the editing">cancel</a>
+  #   </form>
+  # 
+  # The form is serialized and sent to the server using an AJAX call, the action on
+  # the server should process the value and return the updated value in the body of
+  # the reponse. The element will automatically be updated with the changed value
+  # (as returned from the server).
+  # 
+  # Required +options+ are:
+  # <tt>:url</tt>::       Specifies the url where the updated value should
+  #                       be sent after the user presses "ok".
+  # 
+  # Addtional +options+ are:
+  # <tt>:rows</tt>::              Number of rows (more than 1 will use a TEXTAREA)
+  # <tt>:cols</tt>::              Number of characters the text input should span (works for both INPUT and TEXTAREA)
+  # <tt>:size</tt>::              Synonym for :cols when using a single line text input.
+  # <tt>:cancel_text</tt>::       The text on the cancel link. (default: "cancel")
+  # <tt>:save_text</tt>::         The text on the save link. (default: "ok")
+  # <tt>:loading_text</tt>::      The text to display while the data is being loaded from the server (default: "Loading...")
+  # <tt>:saving_text</tt>::       The text to display when submitting to the server (default: "Saving...")
+  # <tt>:external_control</tt>::  The id of an external control used to enter edit mode.
+  # <tt>:load_text_url</tt>::     URL where initial value of editor (content) is retrieved.
+  # <tt>:options</tt>::           Pass through options to the AJAX call (see prototype's Ajax.Updater)
+  # <tt>:with</tt>::              JavaScript snippet that should return what is to be sent
+  #                               in the AJAX call, +form+ is an implicit parameter
+  # <tt>:script</tt>::            Instructs the in-place editor to evaluate the remote JavaScript response (default: false)
+  # <tt>:click_to_edit_text</tt>::The text shown during mouseover the editable text (default: "Click to edit")
