    <<-EOS.undent
      A fixed appliance is required for libguestfs to work on Mac OS X.
      Unless you choose to build --without-fixed-appliance, it's downloaded for
      you and placed in the following path:
      #{HOMEBREW_PREFIX}/var/libguestfs-appliance

      To use the appliance, add the following to your shell configuration:
      export LIBGUESTFS_PATH=#{HOMEBREW_PREFIX}/var/libguestfs-appliance
      and use libguestfs binaries in the normal way.
