 * Available variables:
 * - $author: Comment author. Can be link or plain text.
 * - $content: Body of the comment.

 * - $unpublished: An unpublished comment visible only to administrators.
 * - $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:
 *   - comment: The current template type, i.e., "theming hook".
 *   - comment-by-anonymous: Comment by an unregistered user.
 *   - comment-by-node-author: Comment by the author of the parent node.

 *   - odd: An odd-numbered comment in the list of displayed comments.
 *   - even: An even-numbered comment in the list of displayed comments.

 *   - comment-by-viewer: Comment by the user currently viewing the page.
 *   - comment-unpublished: An unpublished comment visible only to administrators.
 *   - comment-new: New comment since the last visit.
 *
 * These two variables are provided for context:
 * - $comment: Full comment object.
 * - $node: Node object the comments are attached to.
 *
 * Other variables:
 * - $classes_array: Array of html class attribute values. It is flattened
 *   into a string within the variable $classes.
 *
 * The following variables are deprecated and will be removed in Drupal 7:
 * - $date: Formatted date and time for when the comment was created.
 * - $submitted: By line with date and time.
