-cross-project testing tool for Python.
+The `py.test`` testing tool makes it easy to write small tests, yet
+scales to support complex functional testing.  It provides
 
-Platforms: Linux, Win32, OSX
+- `auto-discovery
+  <http://pytest.org/latest/goodpractises.html#python-test-discovery>`_
+  of test modules and functions,
+- detailed info on failing `assert statements <http://pytest.org/latest/assert.html>`_ (no need to remember ``self.assert*`` names)
+- `modular fixtures <http://pytest.org/latest/fixture.html>`_  for
+  managing small or parametrized long-lived test resources.
+- multi-paradigm support: you can use ``py.test`` to run test suites based
+  on `unittest <http://pytest.org/latest/unittest.html>`_ (or trial),
+  `nose <http://pytest.org/latest/nose.html>`_
+- single-source compatibility to Python2.4 all the way up to Python3.3,
+  PyPy and Jython.
 
-Interpreters: Python versions 2.4 through to 3.3, Jython 2.5.1 and PyPy-1.9
+- many `external plugins <http://pytest.org/latest/plugins.html#installing-external-plugins-searching>`_.
 
-Bugs and issues: http://bitbucket.org/hpk42/pytest/issues/
+A simple example for a test::
 
-Web page: http://pytest.org
+    # content of test_module.py
+    def test_function():
+        i = 4
+        assert i == 3
+
+which can be run with ``py.test test_module.py``.  See `getting-started <http://pytest.org/latest/getting-started.html#our-first-test-run>`_ for more examples.
