Sudo (superuser do) allows a system administrator to give certain users (or
groups of users) the ability to run some (or all) commands as root while
logging all commands and arguments. Sudo operates on a per-command basis, it
is not a replacement for the shell. 

The latest version of sudo is cu-sudo v1.5.  There is a web page for sudo at
<http://www.courtesan.com/courtesan/products/sudo/sudo.html>.  The program
itself can be obtained from <ftp://ftp.courtesan.com/pub/sudo/>.  Sudo's
author, Todd Miller < Todd.Miller@courtesan.com> reports that sudo works on
both AIX 3.2.X and 4.1.X.
