 It also clobbers /tmp/differ for good measure.
 
 As you can see, this isn't quite what we're going for.
 
 You'll want to modify diff.py, using the editor you selected earlier.
 You'll probably want to consult the |difflib| documentation.
 I would suggest you check out the HtmlDiff class and make use of
 the make_file member function. Note our goal is to create a
 full HTML diff, so the make_table function is insufficient.

+The splitlines function may also come in handy.
 
 You can test diff.py manually as you would in a normal UNIX environment.
 It can be run like this::
 
   ./diff.py before.txt after.txt out.html
 
-Once everything is working diff.html will contain an html diff.
+Once everything is working, diff.html will contain an html diff.
 After the initial `make` you can hit "Run" to test your changes.
 
 Now get to it, and good luck!
 
 
 What you've learned
 -------------------
 
 While the details of building and packaging Python have been
 insulated from you for the purpose of this exercise, the key take-home lesson
 is how easy it is to leverage Python using PNaCl.
 As you've likely experienced, the initial start time is non-trivial.
 We're working on improving this, both by improving PNaCl,
 and our Python port.
 
 The same approach to deploying Python apps can be used for the other
 interpreted languages that have been ported to PNaCl.
 
 Check out the range of interpreters, libraries, and tools
 `already ported to PNaCl and ready to be integrated with your Web App
 <https://code.google.com/p/naclports/wiki/PortList>`_.
 
 While our in-browser environment is rapidly evolving
 to become a complete development solution,
 for the broadest range of development options, check out the
 `NaCl SDK
