# The mysql-python library is always required for the MySQL engine. We
# depend on it conditionally here because otherwise repoman will balk at
# the potential conflict between PYTHON_TARGETS and USE=mysql. But as a
# result, if you try to use the MySQL engine with python-3.x, it just
# won't work because you'll be missing the library.
