I have the following `tox.ini` file:

```
[tox]
envlist = flake8,py{35,36,37,38}{,-keyring}

[testenv]
usedevelop = True
install_command = pip install -U {opts} {packages}
deps =
    .[test]
    keyring: .[keyring]
setenv =
    COVERAGE_FILE = .coverage.{envname}
commands=
    pytest {toxinidir}/tests -n 4 {posargs}

[testenv:flake8]
basepython = python3
deps = flake8
commands=
    flake8 src tests

[flake8]
ignore: F401,E402,E501,W605,W503

```

When I run the `tox` command, it creates a `.tox` folder containing a folder for every environment specified in the `[tox]` section of the `tox.ini`.

I would like to automatically get rid of these particular folders after the test have succeeded when running `tox` without having to manually run `rm -rf .tox/NAME_OF_THE_ENV`. I have searched through the tox documentation but I have found nothing.

Is it possible to do so? If yes, how?
