# Use -gt 1 to consume two arguments per pass in the loop (e.g. each
# argument has a corresponding value to go with it).
# Use -gt 0 to consume one or more arguments per pass in the loop (e.g.
# some arguments don't have a corresponding value to go with it such
# as in the --default example).
# note: if this is set to -gt 0 the /etc/hosts part is not recognized ( may be a bug )
