  def caveats; <<-EOS.undent
    Plowshare 4 requires Bash 4+. OS X ships with an old Bash 3 version.
    To install Bash 4:
      brew install bash
    EOS
  end
end

# This patch makes sure GNUtools are used on OSX.
# gnu-getopt is keg-only hence the backtick expansion.
# These aliases only exist for the duration of plowshare,
# inside the plowshare shells. Normal operation of bash is
# unaffected - getopt will still find the version supplied
# by OSX in other shells, for example.
