do we want to mandate the BASH_COMPAT aspect in PMS ?
or at least make into a recommendation ?

  local maj=4 min=2
  if ([[ ${BASH_VERSINFO[0]} -lt ${maj} ]] ||
      [[ ${BASH_VERSINFO[0]} -eq ${maj} && ${BASH_VERSINFO[1]} -lt ${min ]]) ; then
    die ">=bash-${maj}.${min} is required"
  fi
  BASH_COMPAT="${maj}.${min}"
