# As of twisted 16.4, trial tries to import the tests as a package (previously
# it loaded the files explicitly), which means they need to be on the
# pythonpath. Our sdist doesn't include the 'tests' package, so normally it
# doesn't work within the tox virtualenv.
#
# As a workaround, we tell tox to do install with 'pip -e', which just
# creates a symlink to the project directory instead of unpacking the sdist.
