+test_description='parallel-checkout: attributes
+
+Verify that parallel-checkout correctly creates files that require
+conversions, as specified in .gitattributes. The main point here is
+to check that the conv_attr data is correctly sent to the workers
+and that it contains sufficient information to smudge files
+properly (without access to the index or attribute stack).
