 * Note that this function uses the 'acme_' prefix to serve as an
 * example for how to use the function within a theme. If this were
 * to be within a class, then the prefix would not be necessary.

 * @param    int    $id    The ID of the post to check
 * @return   bool          True if the post exists; otherwise, false.
 * @since    1.0.0
