Doctest coverage works with nose
(http://somethingaboutorange.com/projects/mrl/nose or easy_install
nose).

Example:

foo.py:

def foo():
    return 'a'

def bar():
    return 'b'

test.txt:

These doctests excercise the 'foo' module.

    >>> import foo
    >>> foo.foo()
    'a'

run:

nosetests -v --with-doctest --doctest-extension=txt --with-coverage
--cover-package=foo

output:

Doctest: test.txt ... ok
