+# The coverage report is only accurate when ran inside a virtualenv
+# created with the --no-site-packages option. When it's not the case,
+# the built-in ignore list is not accurate and third party packages
+# show-up in the report, lowering the overall coverage.

+# starting with /usr/lib/python2.6 while the path in the coverage
+# report starts with /usr/share/pyshared.
