Reading from enviroment variables with validation 

This change allows one to set a environment variables prior to executing
the script. This enables end-users to avoid editing the script itself,
which in turns makes it functionally easier. This also enables end-users
to potentially just drop this script into arbitrary environments without
changing the contents (EG: Docker containers or VMs under configuration
management)
