Rewrite the way parsing sub arguments is made to simplify code and improve maintenability Add -y (NIS) to userdel/usermod pw userdel -r <rootdir> now deletes directories in the rootdir Only parse pw.conf when needed Reject usermod and userdel if the user concerned is not on the user database supposed to be manipulated
