  23   * CKEditor Module for Drupal 6.x
  24   *
  25   * This module allows Drupal to replace textarea fields with CKEditor.
  26   *
  27   * CKEditor is an online rich text editor that can be embedded inside web pages.
  28   * It is a WYSIWYG (What You See Is What You Get) editor which means that the
  29   * text edited in it looks as similar as possible to the results end users will
  30   * see after the document gets published. It brings to the Web popular editing
  31   * features found in desktop word processors such as Microsoft Word and
  32   * OpenOffice.org Writer. CKEditor is truly lightweight and does not require any
  33   * kind of installation on the client computer.
