Thanks.  There also is a tool that (for historic reason) comes with "py",
namely py.convert_unittest, which is always installed with py.test.
Can you imagine to do a proper pytest_convert_unittest repository which
we can then link prominently from pytest.org?  I am sure there are others
who are interested in this.
