+    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.
