-# This is a tiny helper module, to let "python -m allmydata.test.run_trial
-# ARGS" does the same thing as running "trial ARGS" (unfortunately
-# twisted/scripts/trial.py does not have a '__name__=="__main__"' clause).
-#
-# This makes it easier to run trial under coverage from tox:
-# * "coverage run trial ARGS" is how you'd usually do it
-# * but "trial" must be the one in tox's virtualenv
-# * "coverage run `which trial` ARGS" works from a shell
-# * but tox doesn't use a shell
-# So use:
-#  "coverage run -m allmydata.test.run_trial ARGS"
