  24   * FCKeditor Module for Drupal 6.x
  25   *
  26   * This module allows Drupal to replace textarea fields with FCKeditor.
  27   *
  28   * This HTML text editor brings to the web many of the powerful functionalities
  29   * of known desktop editors like Word. It's really  lightweight and doesn't
  30   * require any kind of installation on the client computer.
