Script to update Dell Firmware

There are a few other scripts/tools out there to do this.. but they all seem to have some stupid dependencies (this one is no exception).

#!/bin/bash

# Author: James.Radtke@company.com
# Purpose:  Script to download and apply firmware updates
# Status:   Stable, but likely needs some work

# TODO:     I would like to require a flag to run the REBOOT REQUIRED updates
# Maintained at:   rhnsat01:/root/bin/update_firmware.sh
