  def install
    # ucon64's normal install process installs the discmage library in
    # the user's home folder. We want to store it inside the prefix, so
    # we have to change the default value of ~/.ucon64rc to point to it.
    # .ucon64rc is generated by the binary, so we adjust the default that
    # is set when no .ucon64rc exists.
