However it's done in a horrible way.. it appends the cluster crontab file with the local one and adds '#clustercronData' to each line from the cluster crontab. Resulting in a Tru (pun intended) mess. ------------------------------------------------------- This SF.Net email is sponsored by: YOU BE THE JUDGE.
