There's also the trace module in the Python standard library starting
with Python 2.3.  (It was in Tools/scripts in earlier Pythons.)  The
Zope and ZODB test.py script is hooked up to use that module by using
the -T option.

"python test.py -T" will run the tests and produce annotated coverage
files in the cover directory.  It will also print a summary of all
modules and percentage covered.

I added a little feature to the 2.3 version that deals with
multi-threaded apps that use the threading module.
