+=============
 
-:doc:`Smiley Helper <../helpers/smiley_helper>` function ``js_insert_smiley()`` has been deprecated
-since CodeIgniter 1.7.2 and is now removed. You'll need to switch to ``smiley_js()`` instead.
+The :doc:`Smiley Helper <../helpers/smiley_helper>` is a legacy feature from EllisLab's
+ExpressionEngine product. However, it is too specific for a general purpose framework like
+CodeIgniter and as such it is now deprecated.

+Also, the previously deprecated ``js_insert_smiley()`` (since version 1.7.2) is now removed.

+The :doc:`Cart Library <../libraries/cart>`, similarly to the :doc:`Smiley Helper

 CodeIgniter provides a library to help you with certain common functions
 that you may want to use with Javascript. Please note that CodeIgniter
 does not require the jQuery library to run, and that any scripting
 library will work equally well. The jQuery library is simply presented
 as a convenience if you choose to use it.
