# Maintainer notes:
# - yes, we have to do the trickery with the move for the python functions
#   since the build and test frameworks deduce various settings from the path
#   and they can't be tricked by a symlink. And we also need
#   SUPPORT_PYTHON_ABIS=1 otherwise we can't get pyc/pyo anymore the sane way.
