+ * The formatted output of a list of bookmarks.
+ *
+ * The $bookmarks array must contain bookmark objects and will be iterated over
+ * to retrieve the bookmark to be used in the output.
+ *
+ * The output is formatted as HTML with no way to change that format. However,
+ * what is between, before, and after can be changed. The link itself will be
+ * HTML.
+ *
+ * This function is used internally by wp_list_bookmarks() and should not be
+ * used by themes.
+ *
+ * The defaults for overwriting are:
+ * 'show_updated' - Default is 0 (integer). Will show the time of when the
+ *		bookmark was last updated.
+ * 'show_description' - Default is 0 (integer). Whether to show the description
+ *		of the bookmark.
+ * 'show_images' - Default is 1 (integer). Whether to show link image if
+ *		available.
+ * 'show_name' - Default is 0 (integer). Whether to show link name if
+ *		available.
+ * 'before' - Default is '<li>' (string). The html or text to prepend to each
+ *		bookmarks.
+ * 'after' - Default is '</li>' (string). The html or text to append to each
+ *		bookmarks.
+ * 'link_before' - Default is '' (string). The html or text to prepend to each
+ *		bookmarks inside the <a> tag.
+ * 'link_after' - Default is '' (string). The html or text to append to each
+ *		bookmarks inside the <a> tag.
+ * 'between' - Default is '\n' (string). The string for use in between the link,
+ *		description, and image.
+ * 'show_rating' - Default is 0 (integer). Whether to show the link rating.
+ *
+ * @since 2.1.0
+ * @access private
