 If you're on the ball, you've probably already guessed that you need to create
-a file called F<share/web/templates/fragments/page_of_posts> containing:
-
-  <%args>
-  $page => 1
-  </%args>
-  <%init>
-  my $posts = MyWeblog::Model::PostCollection->new();
-  $posts->unlimit();
-  $posts->set_page_info( current_page => $page,
-                         per_page     => 15
-                       );
-  $m->out("No items found.") if ($posts->pager->total_entries == 0);
+a template called C</fragments/page_of_posts>. Make it contain the following:
 
-  </%init>
-  % if ($posts->pager->last_page > 1) {
-     Page <% $page %> of <% $posts->pager->last_page %>
-  % }
-  <dl class="list">
-  % while (my $post = $posts->next) {
-   <dt><% $post->title %></dt>
-   <dd><% $post->body %></dd>
-  % }
-  </dl>
-
-  % if ($posts->pager->previous_page) {
-    <% Jifty->web->link( label => "Previous Page", onclick => { args => { page => $posts->pager->previous_page } } ) %>
-  % }
-  % if ($posts->pager->next_page) {
-    <% Jifty->web->link( label => "Next Page", onclick => { args => { page => $posts->pager->next_page } } ) %>
-  % }

-Now fire up your Jifty webserver again. Go create a post by browsing C</post>
-on your webserver. Create more than 15 posts, and notice how Jifty gives you
-AJAX C<Next Page> and C<Previous Page> buttons for you. Turn off javascript or
-view the page in lynx, and notice how the AJAX automatically falls-back to page
-loads for you. All for free, thanks to Jifty!
