According to the tox documentation, it is a "virtualenv management tool". So, when I create a new project, do I still need virtualenv if tox can do a better job for multiple Python versions virtual environment setup?
As a follow-up to @sinoroc's answer:
You can also use tox to create a development environment with the following command:
tox devenv my-dev-env
where my-dev-env is an arbitrary path name of your choice in which tox will to create the virtual environment. So in this case tox will create a virtual environment in the my-dev-env directory.
