+      A GNOME based system that will allow a superuser to configure 
+      compressed and uncompressed files and/or file systems to be backed 
+      up with a supported media in the system.  This should be able to 
+      perform via find commands generating a list of files that are passed 
+      to tar, dd, cpio, cp, gzip, etc., to be directed to the tape machine 
+      or via operations performed on the filesystem itself. Email 
+      notification and GUI status display very important.
