  ## TODO: uncomment this on the last point release on 5.x
  #
  #   self.post_install_message = <<-"EOM"
  # NOTE: minitest 5 will be the last in the minitest family to support
  #       ruby 1.8 and 1.9 (and maybe 2.0?). If you need to keep using 1.8
  #       or 1.9, you need to pin your dependency to minitest with
  #       something like "~> 5.0".
  #
  #       Further, minitest 6 will be dropping the following:
  #
  #       + MiniTest (it's been Minitest for *years*)
  #       + MiniTest::Unit
  #       + MiniTest::Unit::TestCase
  #       + assert_send (unless you argue for it well)
  #   EOM
