+I. DESCRIPTION
+
+    KCFinder is an alternative to the CKFinder Web file manager. It can be
+    integrated into FCKeditor, CKEditor, and TinyMCE WYSIWYG web editors or
+    your custom web applications to upload and manage images, flash movies,
+    and other files that can be embedded in an editor's generated HTML
+    content. Only PHP server-side scripting is supported.
