    # smlnj is much easier to build if we do so in the directory where it
    # will be installed.  Thus, we're moving it to the prefix to be built
    # there.

  def caveats
    <<-EOS.undent
    This formula spews ML files all over lib, and puts hidden subfolders in bin.
    Because of this, we've installed it to:
      #{libexec}
    and we haven't linked it into #{HOMEBREW_PREFIX}

    You'll need to add:
      #{libexec}/bin
    to your PATH.

    Improvements are welcome.
