/**
 * @file
 * Bartik's theme implementation to display a node.
 *
 ******************
 * Basic variables:
 ******************
 *
 * The following variables contain HTML-safe strings which can be printed in
 * the template file using a syntax like <?php print $variable; ?>
 *
 * - $title: The title of the node.
 * - $user_picture: The node author's picture from user-picture.tpl.php.
 * - $date: Formatted creation date. Preprocess functions can reformat it by
 *   calling format_date() with the desired parameters on the $created variable.
 * - $name: Themed username of node author output from theme_username().
 * - $node_url: Direct url of the current node.
 * - $submitted: Submission information created from $name and $date during
 *   template_preprocess_node(). Only print this when the $display_submitted
 *   variable is TRUE, since otherwise the site administrator has requested
 *   that it not be displayed.
 * - $classes: String of classes that can be used to style contextually through
 *   CSS. It can be manipulated through the variable $classes_array from
 *   preprocess functions. The default values can be one or more of the
 *   following:
 *   - node: The current template type, i.e., "theming hook".
 *   - node-[type]: The current node type. For example, if the node is a
 *     "Blog entry" it would result in "node-blog". Note that the machine
 *     name will often be in a short form of the human readable label.
 *   - node-teaser: Nodes in teaser form.
 *   - node-preview: Nodes in preview mode.
 *   The following are controlled through the node publishing options.
 *   - node-promoted: Nodes promoted to the front page.
 *   - node-sticky: Nodes ordered above other non-sticky nodes in teaser
 *     listings.
 *   - node-unpublished: Unpublished nodes visible only to administrators.
 *
 * Some of the most important variables required to theme the node are provided
 * as renderable arrays (in the "Advanced variables" section below), for
 * maximum flexibility in the theming layer. For convenience, however, we
 * define basic variables here based on the way we want to render these arrays
 * in this particular template file. As above, these all contain HTML-safe
 * strings which can be printed in the template file using a syntax like
 * <?php print $variable; ?>
 *
 * - $title_prefix_html: HTML that is populated by modules and intended to be
 *   displayed in front of the main title tag that appears in the template.
 *   (This is a rendered version of the $title_prefix array, which can be found
 *   in the "Advanced variables" section below.)
 * - $title_suffix_html: HTML that is populated by modules and intended to be
 *   displayed after the main title tag that appears in the template. (This is
 *   a rendered version of the $title_suffix array, which can be found in the
 *   "Advanced variables" section below.)
 * - $comments_html: HTML containing the comments associated with the node.
 * - $links_html: HTML containing the links associated with the node, such as a
 *   "Read more" link.
 * - $content_html: HTML containing the rendered content of the node, excluding
 *   the comments and links. (This and the variables above it are rendered from
 *   the $content array, which can be found in the "Advanced variables" section
 *   below.)
 *
 ****************
 * Boolean flags:
 ****************
 *
 * The following variables can only take on true/false values and are often
 * used in the template file with a syntax like:
 * <?php if ($variable): ?>
 *   ...
 * <?php endif; ?>
 * to decide whether or not other variables or HTML should be printed.
 *
 * - $teaser: Flag for the teaser state.
 * - $page: Flag for the full page state.
 * - $promote: Flag for front page promotion state.
 * - $sticky: Flags for sticky post setting.
 * - $status: Flag for published status.
 * - $comment: State of comment settings for the node.
 * - $display_submitted: Flag for whether submission information (contained in
 *   the $submitted variable) should be displayed.
 * - $readmore: Flags true if the teaser content of the node cannot hold the
 *   main body content.
 * - $is_front: Flags true when presented in the front page.
 * - $logged_in: Flags true when the current user is a logged-in member.
 * - $is_admin: Flags true when the current user is an administrator.
 *
 *********************
 * Advanced variables:
 *********************
 *
 * The following variables contain renderable arrays which can be printed in
 * the template file using a syntax like <?php print render($variable); ?>. To
 * print part of the array's content without touching the rest, use a syntax
 * like <?php print render($variable['some_key']); ?>. To temporarily suppress
 * the printing of a given element, use <?php hide($variable['some_key']); ?>.
 *
 * - $content: An array of node items making up the main content of the node.
 * - $title_prefix: An array containing additional output populated by modules,
 *   intended to be displayed in front of the main title tag that appears in
 *   the template.
 * - $title_suffix: An array containing additional output populated by modules,
 *   intended to be displayed after the main title tag that appears in the
 *   template.
 *
 * For the specific needs of this template file, these variables are rendered
 * in a particular way, and the resulting HTML strings are stored in new
 * variables (listed in the "Basic variables" section above) which are then
 * printed to the template file directly. The PHP code below shows how this is
 * done and can be modified for more advanced use cases (e.g., if you want to
 * render the variables differently).
 *
 *****************************************************************************/
  // PHP code to prepare the variables described above.
  // This is used for the limited purpose of defining simple, easy-to-print
  // variables that are specific to this template and derived from the
  // renderable arrays provided to us. In general, PHP code to add new
  // variables or for more advanced use cases belongs in a preprocess function
  // in the theme's template.php file, e.g. bartik_preprocess_node(), rather
  // than here.
  $title_prefix_html = render($title_prefix);
  $title_suffix_html = render($title_suffix);
  $comments_html = render($content['comments']);
  // Remove the "Add new comment" link on the teaser page or if the comment
  // form is being displayed on the same page.
  if ($teaser || !empty($content['comments']['comment_form'])) {
    unset($content['links']['comment']['#links']['comment-add']);
  }
  $links_html = render($content['links']);
  $content_html = render($content);
/******************************************************************************
 *
 ******************
 * Other variables:
 ******************
 *
 * The following variables are less commonly used.
 *
 * - $node: Full node object. Contains data that may not be safe.
 * - $type: Node type, i.e. story, page, blog, etc.
 * - $view_mode: The node's view mode, e.g. 'full', 'teaser'...
 * - $comment_count: Number of comments attached to the node.
 * - $uid: User ID of the node author.
 * - $created: Time the node was published formatted in Unix timestamp.
 * - $classes_array: Array of html class attribute values. It is flattened
 *   into a string within the variable $classes.
 * - $zebra: Outputs either "even" or "odd". Useful for zebra striping in
 *   teaser listings.
 * - $id: Position of the node. Increments each time it's output.
 *
 ******************
 * Field variables:
 ******************
 *
 * For each field instance attached to the node a corresponding variable is
 * defined, e.g. $node->body becomes $body. When needing to access a field's
 * raw values, developers/themers are strongly encouraged to use these
 * variables. Otherwise they will have to explicitly specify the desired field
 * language, e.g. $node->body['en'], thus overriding any language negotiation
 * rule that was previously applied.

 * @see template_preprocess_node()
