# Tox  is a tool for running tests in multiple virtualenvs.
#
# To run this, from the update repo root directory, execute the following:
# - Install python3.9:  apt install python3.9 python3.9-pip python3.9-venv
# - Create a py39 venv:  python3.9 -m venv .venv
# - Source the venv:  source .venv/bin/activate
# - Install tox in the venv:  pip install tox
# - Run tox:  tox -c software-client/tox.ini
