# therefore the generated Python module is not copied into the build

# Bugs: https://bugs.python.org/issue1016626
# https://bugs.python.org/issue2624
# Workaround:
# https://stackoverflow.com/questions/12491328/python-distutils-not-include-the-swig-generated-module
#
# To install to multiple Python installations or to alternate ones run the
# following three commands (yes, run the build one twice):
#
# /path/to/pythonX.Y setup.py build
# /path/to/pythonX.Y setup.py build
# /path/to/pythonX.Y setup.py install
#
# It is highly likely that this will need to be run as root or with sudo (or
# sudo -H). It may or may not work with venv. and outside a virtualenv
