In this class, we will follow Jon as he demonstrates binary rewriting.
To get ready for this class:

(1) Please fetch Jon's demo and slide kit

(2) Untar it:
    $ tar -xzvf howell.tar.gz

(3) Build his kit on a 32-bit machine.

    (a) Here is a list of 32-bit UTCS machines:
	http://apps.cs.utexas.edu/unixlabstatus/

    (b) Here are the build instructions:
	    $ cd howell
	    $ make

(4) Test that the code built properly:
    $ cd build
    $ ./hello_rewritten
	(you should see something that looks like, but is not, "hello
	world")

(5) If the code did not build properly, then please send the course
staff email.

(6) Please skim the code and skim Jon's lecture notes, in preparation
for his demo. Laptops are encouraged for this class.
