   3 # Linux/MacOS X script to install rEFInd
   4 #
   5 # Usage:
   6 #
   7 # ./install.sh [esp]
   8 #
   9 # The "esp" option is valid only on Mac OS X; it causes
  10 # installation to the EFI System Partition (ESP) rather than
  11 # to the current OS X boot partition. Under Linux, this script
  12 # installs to the ESP by default.
