-# virtualenv installs custom distutils/__init__.py and
-# distutils/distutils.cfg files which essentially proxy back to the
-# "real" distutils in the main Python install. The presence of this
-# directory causes py2exe to pick up the "hacked" distutils package
-# 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
-# venv, which is likely what Python 3 uses).
