=head1 NAME
pam_getenv - get environment variables from /etc/environment
=head1 SYNOPSIS
pam_getenv B<[-l] [-s]> I<env_var>
=head1 DESCRIPTION
This tool will print out the value of I<env_var> from F</etc/environment>. It will attempt to expand environment variable references in the definition of I<env_var> but will fail if PAM items are expanded.
The B<-l> option indicates the script should return an environment variable related to default locale information.
The B<-s> option indicates that the script should return an
system default environment variable.
Currently neither the B<-l> or B<-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.
