-      # Returns a link that will allow unobtrusive JavaScript to dynamical adjust its

-      # into a DOM object whose id can be specified with <tt>options[:update]</tt>. Usually, 
-      # the result would be a partial prepared by the controller with render :partial.
-      #

-      #   #     <a href="#" 
-      #   #        data-remote="true"

-      #
-      #
-      # You can override the generated HTML options by specifying a hash in
-      # <tt>options[:html]</tt>.
-      #
-      #   # Generates:
-      #   #     <a class="fine" 
-      #   #        href="#" 
-      #   #        data-remote="true" 
-      #   #        data-url="http://www.example.com/whatnot"
-      #   #        data-method="delete"

-      #
-      #
-      # You can also specify a hash for <tt>options[:update]</tt> to allow for
-      # easy redirection of output to an other DOM element if a server-side
-      # error occurs:
-      #
-      # Example:
-      #   # Generates: 
-      #   #
-      #   #     <a href="#" 
-      #   #        data-url="http://www.example.com/destroy" 
-      #   #        data-update-success="posts" 
-      #   #        data-update-failure="error" 
-      #   #        data-remote="true">Delete this Post</a>'
-      #   #
-      #   link_to_remote "Delete this post",
-      #     :url => { :action => "destroy"},
-      #     :update => { :success => "posts", :failure => "error" }
-      #
-      # Optionally, you can use the <tt>options[:position]</tt> parameter to
-      # influence how the target DOM element is updated. It must be one of
-      # <tt>:before</tt>, <tt>:top</tt>, <tt>:bottom</tt>, or <tt>:after</tt>.
-      #
-      # Example:
-      #   # Generates:
-      #   #     <a href="#" 
-      #   #        data-remote="true" 
-      #   #        data-url="http://www.example.com/whatnot" 
-      #   #        data-update-position="bottom">Remove Author</a>
-      #   #
-      #   link_to_remote("Remove Author", :url => { :action => "whatnot" }, :position => :bottom)
-      #
-      #
-      # The method used is by default POST. You can also specify GET or you
-      # can simulate PUT or DELETE over POST. All specified with <tt>options[:method]</tt>
-      #
-      # Example:
-      #   # Generates: 
-      #   #     <a href='#'
-      #   #        data-url='/person/4' 
-      #   #        rel='nofollow' 
-      #   #        data-remote='true' 
-      #   #        data-method='delete'>Destroy</a>
-      #   #
-      #   link_to_remote "Destroy", :url => person_url(:id => person), :method => :delete
-      #
-      # By default, these remote requests are processed asynchronous during
-      # which various JavaScript callbacks can be triggered (for progress
-      # indicators and the likes). All callbacks get access to the
-      # <tt>request</tt> object, which holds the underlying XMLHttpRequest.
-      #
-      # To access the server response, use <tt>request.responseText</tt>, to
-      # find out the HTTP status, use <tt>request.status</tt>.
-      #
-      # Example:
-      #   # Generates: 
-      #   #
-      #   #     <a href='#' 
-      #   #        data-url='http://www.example.com/undo?n=5' 
-      #   #        data-oncomplete='undoRequestCompleted(request)' 
-      #   #        data-remote='true'>undo</a>
-      #   #
-      #   link_to_remote "undo",
-      #     :url => { :controller => "words", :action => "undo", :n => word_counter },
-      #     :complete => "undoRequestCompleted(request)"
-      #
-      # The callbacks that may be specified are (in order): 
-      #
-      # <tt>:loading</tt>::       Called when the remote document is being
-      #                           loaded with data by the browser.
-      # <tt>:loaded</tt>::        Called when the browser has finished loading
-      #                           the remote document.
-      # <tt>:interactive</tt>::   Called when the user can interact with the
-      #                           remote document, even though it has not
-      #                           finished loading.
-      # <tt>:success</tt>::       Called when the XMLHttpRequest is completed,
-      #                           and the HTTP status code is in the 2XX range.
-      # <tt>:failure</tt>::       Called when the XMLHttpRequest is completed,
-      #                           and the HTTP status code is not in the 2XX
-      #                           range.
-      # <tt>:complete</tt>::      Called when the XMLHttpRequest is complete
-      #                           (fires after success/failure if they are
-      #                           present).
-      #
-      # You can further refine <tt>:success</tt> and <tt>:failure</tt> by
-      # adding additional callbacks for specific status codes.
-      #
-      # Example:
-      #
-      #   # Generates:  
-      #   #     <a href='/testing/action'
-      #   #        date-remote='true'
-      #   #        data-failure="function(request){alert('HTTP Error '+ request.status +'+!');return false}"
-      #   #        data-404="function(request){alert('Not found...? Wrong URL...?')}"> Hello</a>
-      #   #
-      #   link_to_remote word,
-      #     :url => { :action => "action" },
-      #     404 => "alert('Not found...? Wrong URL...?')",
-      #     :failure => "alert('HTTP Error ' + request.status + '!')"
-      #
-      # A status code callback overrides the success/failure handlers if
-      # present.
-      #
-      # If you for some reason or another need synchronous processing (that'll
-      # block the browser while the request is happening), you can specify
-      # <tt>options[:type] = :synchronous</tt>.
-      #
-      # You can customize further browser side call logic by passing in
-      # JavaScript code snippets via some optional parameters. In their order
-      # of use these are:
-      #
-      # <tt>:confirm</tt>::      Adds confirmation dialog.
-      # <tt>:condition</tt>::    Perform remote request conditionally
-      #                          by this expression. Use this to
-      #                          describe browser-side conditions when
-      #                          request should not be initiated.
-      # <tt>:before</tt>::       Called before request is initiated.
-      # <tt>:after</tt>::        Called immediately after request was
-      #                          initiated and before <tt>:loading</tt>.
-      # <tt>:submit</tt>::       Specifies the DOM element ID that's used
-      #                          as the parent of the form elements. By
-      #                          default this is the current form, but
-      #                          it could just as well be the ID of a
-      #                          table row or any other DOM element.
-      # <tt>:with</tt>::         A JavaScript expression specifying
-      #                          the parameters for the XMLHttpRequest.
-      #                          Any expressions should return a valid
-      #                          URL query string.
-      #
-      #                          Example:
-      #
-      #                            :with => "'name=' + $('name').value"
-      #
-      # You can generate a link that uses the UJS drivers in the general case, while
-      # degrading gracefully to plain link behavior in the absence of
-      # JavaScript by setting <tt>html_options[:href]</tt> to an alternate URL.
-      # Note the extra curly braces around the <tt>options</tt> hash separate
-      # it as the second parameter from <tt>html_options</tt>, the third.

-      #                       when the field has changed.
-      # <tt>:function</tt>::  Instead of making a remote call to a URL, you
-      #                       can specify javascript code to be called instead.
-      #                       Note that the value of this option is used as the
-      #                       *body* of the javascript function, a function definition
-      #                       with parameters named element and value will be generated for you
-      #                       for example:
-      #                         observe_field("glass", :frequency => 1, :function => "alert('Element changed')")
-      #                       will generate:
-      #                         new Form.Element.Observer('glass', 1, function(element, value) {alert('Element changed')})
-      #                       The element parameter is the DOM element being observed, and the value is its value at the
-      #                       time the observer is triggered.
-      #
-      # Additional options are:
-      # <tt>:frequency</tt>:: The frequency (in seconds) at which changes to
-      #                       this field will be detected. Not setting this
-      #                       option at all or to a value equal to or less than
-      #                       zero will use event based observation instead of
-      #                       time based observation.
-      # <tt>:update</tt>::    Specifies the DOM ID of the element whose
-      #                       innerHTML should be updated with the
-      #                       XMLHttpRequest response text.
-      # <tt>:with</tt>::      A JavaScript expression specifying the parameters
-      #                       for the XMLHttpRequest. The default is to send the
-      #                       key and value of the observed field. Any custom
-      #                       expressions should return a valid URL query string.
-      #                       The value of the field is stored in the JavaScript
-      #                       variable +value+.
-      #
-      #                       Examples
-      #
-      #                         :with => "'my_custom_key=' + value"
-      #                         :with => "'person[name]=' + prompt('New name')"
-      #                         :with => "Form.Element.serialize('other-field')"
-      #
-      #                       Finally
-      #                         :with => 'name'
-      #                       is shorthand for
-      #                         :with => "'name=' + value"
-      #                       This essentially just changes the key of the parameter.
-      #
-      # Additionally, you may specify any of the options documented in the
-      # <em>Common options</em> section at the top of this document.
-      #
-      # Example:
-      #
-      #   # Sends params: {:title => 'Title of the book'} when the book_title input
-      #   # field is changed.
-      #   observe_field 'book_title',

+      #                           loaded with data by the browser.

+      #                           the remote document.
+      # <tt>:interactive</tt>::   Called when the user can interact with the
+      #                           remote document, even though it has not
+      #                           finished loading.
+      # <tt>:success</tt>::       Called when the XMLHttpRequest is completed,
+      #                           and the HTTP status code is in the 2XX range.
+      # <tt>:failure</tt>::       Called when the XMLHttpRequest is completed,

+      #                           range.

+      #
+      # You can further refine <tt>:success</tt> and <tt>:failure</tt> by

+      # A status code callback overrides the success/failure handlers if

+      #
+      # If you for some reason or another need synchronous processing (that'll

+      # JavaScript code snippets via some optional parameters. In their order
+      # of use these are:
+      #
+      # <tt>:confirm</tt>::      Adds confirmation dialog.
+      # <tt>:condition</tt>::    Perform remote request conditionally
+      #                          by this expression. Use this to
+      #                          describe browser-side conditions when
+      #                          request should not be initiated.
+      # <tt>:before</tt>::       Called before request is initiated.
+      # <tt>:after</tt>::        Called immediately after request was
+      #                          initiated and before <tt>:loading</tt>.
+      # <tt>:submit</tt>::       Specifies the DOM element ID that's used
+      #                          as the parent of the form elements. By
+      #                          default this is the current form, but
+      #                          it could just as well be the ID of a
+      #                          table row or any other DOM element.
+      # <tt>:with</tt>::         A JavaScript expression specifying
+      #                          the parameters for the XMLHttpRequest.
+      #                          Any expressions should return a valid
+      #                          URL query string.
+      #
+      #                          Example:
+      #
+      #                            :with => "'name=' + $('name').value"
+      #
+      # You can generate a link that uses AJAX in the general case, while
+      # degrading gracefully to plain link behavior in the absence of
+      # JavaScript by setting <tt>html_options[:href]</tt> to an alternate URL.
+      # Note the extra curly braces around the <tt>options</tt> hash separate
+      # it as the second parameter from <tt>html_options</tt>, the third.
+      #
+      # Example:
+      #   link_to_remote "Delete this post",
+      #     { :update => "posts", :url => { :action => "destroy", :id => post.id } },

+      # Periodically calls the specified url (<tt>options[:url]</tt>) every
+      # <tt>options[:frequency]</tt> seconds (default is 10). Usually used to

+      # of the remote call. The options for specifying the target with <tt>:url</tt>
+      # and defining callbacks is the same as link_to_remote.
+      # Examples:
+      #  # Call get_averages and put its results in 'avg' every 10 seconds
+      #  # Generates:
+      #  #      new PeriodicalExecuter(function() {new Ajax.Updater('avg', '/grades/get_averages',

+      #  # Call invoice every 10 seconds with the id of the customer
+      #  # If it succeeds, update the invoice DIV; if it fails, update the error DIV
+      #  # Generates:
+      #  #      new PeriodicalExecuter(function() {new Ajax.Updater({success:'invoice',failure:'error'},
+      #  #      '/testing/invoice/16', {asynchronous:true, evalScripts:true})}, 10)

+      #     :update => { :success => "invoice", :failure => "error" }
+      #
+      #  # Call update every 20 seconds and update the new_block DIV
+      #  # Generates:
+      #  # new PeriodicalExecuter(function() {new Ajax.Updater('news_block', 'update', {asynchronous:true, evalScripts:true})}, 20)

+      #
+      # The Hash passed to the <tt>:html</tt> key is equivalent to the options (2nd)
+      # argument in the FormTagHelper.form_tag method.
