pam_getenv [-l] [-s] env_var
This tool will print out the value of env_var from /etc/environment.

The -l option indicates the script should return an environment
variable related to default locale information.
The -s option indicates that the script should return an system default
Currently neither the -l or -s options do anything. They are included
because future versions of Debian may have a separate repository for
the initial environment used by init scripts and for system locale
information. These options will allow this script to be a stable
interface even in that environment.
