Code Coverage support for unittest?

[Michael Chermside]

I was reading this:

http://www.amk.ca/python/writing/mx-architecture/#SECTION000800000000000000000

and the author referred to using a modified version of Skip Montanaro's 
trace.py to get CODE COVERAGE reporting for unit tests written using the 
unittest module.

Really? How? I must have missed this in the docs! It sounds great... 
does anyone know the details, or where (if at all) it's documented?
