# @TODO: Get rid of this if possible in Debian Buster.

# Do not install setuptools when creating the virtual environment -

# otherwise it will also install Debian-specific pkg-resources

# package. The pkg-resources package can be removed, but this breaks

# the package downloading via pip.

#

# Install setuptools later on via separate pip invocation.

#

# The pkg-resources package is also annoying because it shows-up in

# the output of the pip freeze command, and also interferes with the

# virtual environment management using pip-tools.
