Testing if a script is run via sudo

Is tehre a way to test if a ruby script is run as a sudoer user ?

For the time being i'm using a zsh script to test that however I'd like
using ruby only.

the zsh i'm using :
#! /usr/bin/env zsh

[ "$SUDO_USER" -a `id -u` -eq 0 ] || {
  echo "false"
  exit 0
}
echo "true"
exit 0

on my system, echo $USER gives root under sudo (mac os x).

So in ruby:

ENV['USER']

will return root under sudo user, and my name normally.

Note that here i have done a "sudo bash" first.

A cleaner way would be to use the Process::UID module, namely the #eid method.
