# from the virtualenv and "import distutils" will fail from the py2exe
# build because the "real" distutils files can't be located.
#
# We work around this by monkeypatching the py2exe code finding Python
# modules to replace the found virtualenv distutils modules with the
# original versions via filesystem scanning. This is a bit hacky. But
# it allows us to use virtualenvs for py2exe packaging, which is more
# deterministic and reproducible.
#
# It's worth noting that the common StackOverflow suggestions for this
# problem involve copying the original distutils files into the
# virtualenv or into the staging directory after setup() is invoked.
# The former is very brittle and can easily break setup(). Our hacking
# of the found modules routine has a similar result as copying the files
# manually. But it makes fewer assumptions about how py2exe works and
# is less brittle.
# This only catches virtualenvs made with virtualenv (as opposed to
