  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.
