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.
