# @(#)/usr/local/share/etc/env.src  1999-08-07 Markus Gyger <mgyger@gmu.edu>

# This file can be sourced in by different flavours of shells (newer sh,
# ksh, bash, csh, tcsh, etc.) on various OS (Solaris, HP-UX, etc.) so that
# environment variables can be defined in one place and the environments
# of the different shells don't get out of sync.
#
# Put the following at the end of /etc/profile to enable it on sh-like shells:
#
#   if [ -r /usr/local/share/etc/env.src ]
#   then . /usr/local/share/etc/env.src
#   fi
#
# and append the following to /etc/.login for the csh-like shells:
#
#   if (-r /usr/local/share/etc/env.src) source /usr/local/share/etc/env.src
#
# Available keywords (commands):
#
#   setenv   <VAR> <value>      # set environment variable
#   unsetenv <VAR>              # undef environment variable
#   ifndef   <VAR> <value>      # set variable only if not defined yet
#   ifnull   <VAR> <value>      # set variable if not defined or empty
#   append   <VAR> <path>       # append  path separated by :
#   prepend  <VAR> <path>       # prepend path separated by :

# The following sets up above mentioned commands if they are not native
# to the used shell already. It looks a bit cryptic because some shells
# are rather buggy...
