# Example shell usage to populate environment in a sourced script:
# for line in $(linuxcnc_var all) ; do
# name=${line%%=*}

# echo "name=$name value=$value"
# export "$name"="$value"

# Example tcl usage:
# foreach line [exec linuxcnc_var all] {
# set l [split $line =]
# set name [lindex $l 0]
# set value [lindex $l 1]
# set V($name) $value
# }

# Example python usage:
# import subprocess
# s = subprocess.Popen(['linuxcnc_var','all']
# ,stdout=subprocess.PIPE
# ,stderr=subprocess.PIPE
# p,e = s.communicate()
# v={}
# for line in p.split('\n'):
