Summary : Allows restricted root access for specified users.

Description : 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. Features include: the ability to restrict
: what commands a user may run on a per-host basis, copious logging of each
: command (providing a clear audit trail of who did what), a configurable timeout
: of the sudo command, and the ability to use the same configuration file
: (sudoers) on many different machines.
