# This is a demo for the problem in https://github.com/pleiszenburg/wenv/issues/14
#
# it builds yamlreader into an executable. First on Linux and then in wine.
#
# Building it in wine fails, I hope that this test case helps to extend wenv to support this sort of "cross building"
# to allow creating Windows executables from Python programs without actually running Windows, e.g. in a CI pipeline.
#
# Build like this: docker build .
#
# Optionally set the Pyhon version like this: docker build --build-arg PYTHONVERSION=3.8.1 .
