-# This is the configuration file for pam_env, a PAM module to load in
-# a configurable list of environment variables for a
-#
-# The original idea for this came from Andrew G. Morgan ...
-#<quote>
-# Mmm. Perhaps you might like to write a pam_env module that reads a
-# default environment from a file? I can see that as REALLY
-# useful... Note it would be an "auth" module that returns PAM_IGNORE
-# for the auth part and sets the environment returning PAM_SUCCESS in
-# the setcred function...

-# What I wanted was the REMOTEHOST variable set, purely for selfish
-# reasons, and AGM didn't want it added to the SimpleApps login
-# program (which is where I added the patch). So, my first concern is
-# that variable, from there there are numerous others that might/would
-# be useful to be set: NNTPSERVER, LESS, PATH, PAGER, MANPAGER .....
-#
-# Of course, these are a different kind of variable than REMOTEHOST in
-# that they are things that are likely to be configured by
-# administrators rather than set by logging in, how to treat them both
-# in the same config file?
-#
-# Here is my idea:
-#
-# Each line starts with the variable name, there are then two possible
-# options for each variable DEFAULT and OVERRIDE.
-# DEFAULT allows and administrator to set the value of the
-# variable to some default value, if none is supplied then the empty
-# string is assumed. The OVERRIDE option tells pam_env that it should
-# enter in its value (overriding the default value) if there is one
-# to use. OVERRIDE is not used, "" is assumed and no override will be
-# done.
-#
-# VARIABLE [DEFAULT=[value]] [OVERRIDE=[value]]
-#
-# (Possibly non-existent) environment variables may be used in values
-# using the ${string} syntax and (possibly non-existent) PAM_ITEMs may
-# be used in values using the @{string} syntax. Both the $ and @
-# characters can be backslash escaped to be used as literal values
-# values can be delimited with "", escaped " not supported.
-#
-#
-# First, some special variables
-#
-# Set the REMOTEHOST variable for any hosts that are remote, default
-# to "localhost" rather than not being set at all
-REMOTEHOST DEFAULT=localhost OVERRIDE=@{PAM_RHOST}
-#
-# Set the DISPLAY variable if it seems reasonable
-DISPLAY DEFAULT=${REMOTEHOST}:0.0 OVERRIDE=${DISPLAY}
-#
-#
-# Now some simple variables
-#
-PAGER DEFAULT=less
-MANPAGER DEFAULT=less
-LESS DEFAULT="M q e h15 z23 b80"
-NNTPSERVER DEFAULT=localhost
-PATH DEFAULT=${HOME}/bin:/usr/local/bin:/bin\
-:/usr/bin:/usr/local/bin/X11:/usr/bin/X11
-#
-# silly examples of escaped variables, just to show how they work.
