 /**
  * Generates a tag cloud (heatmap) from provided data.
  *
- * The text size is set by the 'smallest' and 'largest' arguments, which will
- * use the 'unit' argument value for the CSS text size unit. The 'format'
- * argument can be 'flat' (default), 'list', or 'array'. The flat value for the
- * 'format' argument will separate tags with spaces. The list value for the
- * 'format' argument will format the tags in a UL HTML list. The array value for
- * the 'format' argument will return in PHP array type format.
- *
- * The {@see 'tag_cloud_sort'} filter allows you to override the sorting.
- * Passed to the filter: $tags array and $args array, has to return the $tags array
- * after sorting it.
- *
- * The 'orderby' argument will accept 'name' or 'count' and defaults to 'name'.
- * The 'order' is the direction to sort, defaults to 'ASC' and can be 'DESC' or
- * 'RAND'.
- *
- * The 'number' argument is how many tags to return. By default, the limit will
- * be to return the entire tag cloud list.
- *
- * The 'topic_count_text' argument is a nooped plural from _n_noop() to generate the
- * text for the tooltip of the tag link.
- *
- * The 'topic_count_text_callback' argument is a function, which given the count
- * of the posts with that tag returns a text for the tooltip of the tag link.
- *
  * @todo Complete functionality.
  * @since 2.3.0
