+=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.
