  def message; <<-EOS.undent
    The version of Freetype that comes with Leopard is too old to build MuPDF
    against. It is possible to get MuPDF working on Leopard using the Freetype
    formula from Homebrew-Dupes and some tweaks to the Makefile.

    Doing so is left as an exercise for the reader.

    # MuPDF comes with some handy command-line tools. However, their names can
    # clash with other tools installed by formulae such as Poppler. So, we
    # add a `mu` prefix to every binary that starts with `pdf`.
    bin.entries.select{ |b| b.basename.to_s.match /^pdf/ }.each do |p|
      mv bin + p, bin + ('mu' + p.basename.to_s)
    end
  end

  def caveats; <<-EOS.undent
    All MuPDF command line tools have been prefixed with `mu` to prevent name
    clashes with other PDF packages.

Remove some Makefile rules that Homebrew takes care of through CFLAGS and
LDFLAGS. MuPDF doesn't look at CPPFLAGS, so we piggyback it onto CFLAGS.
