# PYTHONDONTWRITEBYTECODE=yes keeps Python 2.6+ from creating .pyc and .pyo

# vSwitch, but it causes trouble if you switch from a version with
# foo/__init__.py into an (older) version with plain foo.py, since
# foo/__init__.pyc will cause Python to ignore foo.py.
#
# Python before version 2.6 always creates .pyc files, so if you develop
# with such an older version then you're out of luck.
