  $output .= "<p>The page module is used to create a <i>static page</i>.  Unlike a story, a static page is a persistent web page on your site which usually shortcuts the typical lifecycle of user generated content (i.e. submit -&gt; moderate -&gt; post -&gt; comment).  A static page is usually linked from the main navigation bar, using whatever text the author wishes.  To create a static page without this navigation link, simply skip the form field which requests link text.</p>";
  $output .= "<p>Site pages, unlike many other forms of Drupal content, may be made of PHP code in addition to HTML and text. All Drupal objects and functions are available to a site administrator.</p>";
