    longDescription = ''
      rEFInd is a graphical boot manager for EFI- and UEFI-based
      computers, such as all Intel-based Macs and recent (most 2011
      and later) PCs. rEFInd presents a boot menu showing all the EFI
      boot loaders on the EFI-accessible partitions, and optionally
      BIOS-bootable partitions on Macs. EFI-compatbile OSes, including
      Linux, provide boot loaders that rEFInd can detect and
      launch. rEFInd can launch Linux EFI boot loaders such as ELILO,
      GRUB Legacy, GRUB 2, and 3.3.0 and later kernels with EFI stub
      support. EFI filesystem drivers for ext2/3/4fs, ReiserFS, HFS+,
      and ISO-9660 enable rEFInd to read boot loaders from these
      filesystems, too. rEFInd's ability to detect boot loaders at
      runtime makes it very easy to use, particularly when paired with
      Linux kernels that provide EFI stub support.
