+"""This plugin provides test results in the standard XUnit XML format.
+
+It's designed for the `Jenkins`_ (previously Hudson) continuous build
+system, but will probably work for anything else that understands an
+XUnit-formatted XML representation of test results.
+
+Add this shell command to your builder ::
+
+    nosetests --with-xunit
+
+And by default a file named nosetests.xml will be written to the
+working directory.
+
+In a Jenkins builder, tick the box named "Publish JUnit test result report"
+under the Post-build Actions and enter this value for Test report XMLs::
+
+    **/nosetests.xml
+
+If you need to change the name or location of the file, you can set the
+``--xunit-file`` option.
+
+Here is an abbreviated version of what an XML test report might look like::
+
+    <?xml version="1.0" encoding="UTF-8"?>
+    <testsuite name="nosetests" tests="1" errors="1" failures="0" skip="0">
+        <testcase classname="path_to_test_suite.TestSomething"
