+Running the tests is simple. Make sure you have nose installed and run

+The script can take any of the usual `nosetest arguments`_, such as
+
+===================  ===========
+``-v``               increase verbosity
+``-d``               detailed error messages
+``--with-coverage``  enable collecting coverage information
+===================  ===========
+
+To run a single test from the command line, you can provide a
+dot-separated path to the module followed by the function separated by
+a colon, eg.  (this is assuming the test is installed)::
+
+  python tests.py matplotlib.tests.test_simplification:test_clipping
+
+An alternative implementation that does not look at command line
+arguments works from within Python::
 
   import matplotlib
   matplotlib.test()
