 and maybe some pictures of your cat doing funny stuff. Since this is
 all of vital importance, you need to back it up.

 One caveat: it's way more efficient to do this:
 
-  # do two things per file
-  directory.files.each do |file|
-    do_one_thing(file)
-    do_another_thing(file)
-  end
+    # do two things per file
+    directory.files.each do |file|

+      do_one_thing(file)
+    end.each do |file|

 The reason is that the list of files might be large. Really
