My bad, I was even looking at it other day but when I compiled this
list of packages I looked only in trunk and forgot about the py3k

This made me remember about another two features I think would be
useful to have.
One of these features would allow me to restrict from which packages I
want to collect tests, this is useful even in "flat packages" (no
sub-packages) like tkinter where some of its modules possibly depend
on external packages in order to be tested/executed. This adds the
possibility to skip tests of single modules instead of entire
Other one would be able to check the requirements of a test and decide
to collect it or not based on some parameters given. So I could
collect all the tests that require a GUI, and others that do not, for
example. This adds the possibility to skip single tests, or at least
the possibility to divide the tests before running.
