  def caveats; <<-EOS.undent
    For SleepWatcher to work, you will need to read the following:

      #{prefix}/ReadMe.rtf

    Ignore information about installing the binary and man page,
    but read information regarding setup of the launchd files which
    are installed here:

      #{Dir[(prefix + '*.plist')].join("\n      ")}

    These are the examples provided by the author.
